Downgrade iPhone Firmware 2.2 To 2.1

ziphone by kirem gets stuck on recovery mode.. how long is it supposed to take to downgrade the baseband?

Got stuck, I don't think it accessed the iphone as the recovery mode splash didn't change.

i tried it and i got that error message shown in the screenshot (i didnt follow that link to get ziphone i used a different version that has that same look) well i got that same error "This application has requested the Runtime to terminate in an unusual way" and i just figured it probobly wasnt gonna work and stopped there but it didnt make my phone stuck i dont think it did anything to it...

I get the same screens as above - including the 1013 error which is exactly what I got before and it does not restore 2.1
In fact ziphone does not appear to do anything :(

Tried again (this time I selected iErase as well.
Still got the 1013 Error but it worked! :D

I'm now back to 2.1

Yay!!!

Many thanks

are you sure because i tried that and i keep getting stuck on the recovery screen...is it supposed to do that? if so how long and could you please post the link you used to download zphone? thanks!

I followed this process step by step. The ZiPhone programme did stay on but as iTunes launched and wanted me to restore the firmware, I went on to step 2. The ZiPhone programme then closed a couple of minutes into step 2. Then went on to step 3 after click OK on the error and hey presto my iPhone is back in 2.1 and fully jailbroken.

But....it appears the the baseband didn't get downgraded. What this means is the iPhone is now on firmware 2.1 and i can use it with Itunes etc. However my turbosim still doesn't work.

Does anyone have any ideas??

I followed the instructions closely the quickpwn and itunes steps were flawless however the initial step with ZiPhone doesnt work. It just sits there after putting your phone into recovery mode and doesnt do anything.

Are there any better instructions or a link to ZiPhone that actually works??

I also followed the instructions but Ziphone get stuck after putting the phone into recovery mode

Any suggestions?

I too am having the same issue as other posters. I can successfully downgrade to 2.1 but the baseband is not downgraded either which means I can't use my turbosim :( I'm not sure that there is any solution to this as from what I can gather the baseband cannot be downgraded in 2.2. Please someone tell me I'm wrong?

i used pwntools and that worked as well to restore the 2.1 firmware and ipod and wifi capabilities, but only for the firmware, i think we're going to have to wait for a baseband solution

how is everybody getting that ziphone thing to work its not working for me...=( can someone post step by step instructions please

can not get it to downgrade, been trying for hours :(

I think it's time to give up and wait for the Dev Boys to come up with something that works. I've been trying all last night and all day today and cannot get the baseband to downgrade.

I suggest you just enjoy your iPhone as an iTouch until a reliable baseband downgrade method is posted or the TurboSIM people release a hardware sim hack that works on 2.2 firmware.

do you know if exists a version of
ZiPhone patched by kIREmK
for mac ??
thank's

I've had my iPhone 3G for a while, and since I'm supporting it in 2nd line I've kept it original. But yesterday I finally decided to jailbreak my iPhone. Well, it was nice and I found out how much a locked iPhone is missing.
Well, not having the time to scan iPhoneforums and such I got the news that the 2.2 FW was released and asked if I wanted to upgrade to it. So I did. And about 2 mins after hitting the upgrade button my friends shouts on MSN "Whatever you do, do NOT upgrade your FW"... Well.. What can I say. Can't downgrade it =/ Been trying since yesterday. Can't get ZiPhone to work either (running Vista Ultiamte)... Guees I'm stuck with a 10% iPhone for a while...

Cheers

This is fake, its a solution for 2G phones, copied and labeled 3G, which it dont work for.
When you get 2.2 you get a new baseband, its not (as of today) possible to downgrade.

If you use Turbosim/Rebelsim or any other hardware-unlock method, your screwed.

You can still downgrade to 2.1 and use WiFi, but as for using it as a phone, either your hard-unlock provider need to make a new firmare, dev team, or your really screwed (never gonna get the phone to work again with your non-auth provider)

This just does not work.

I managed to get it not working as a phone at all on 2.1 so have reverted to 2.2. At least I can use it on O2 on 2.2 :(

The Dev Team did warn us not to upgrade so owe us nothing. They might decide not to bother hacking 2.2! I hope they think we're worth it!

Don't even ask me I used the applications in here and I was getting really frustrated after having to go back to 2.2 many times and starting again I finally kinda got got quickpwn working but then it quit and I was in restore mode and when I tried to upgrade again to 2.2 it came with error 2001. I figured I'd try DFU mode and Im not sure if I did the right button sequence but it got the apple and went into the 2.1 software! So surprised but unjailbroken. Thats fine I have a mac so I did it with pwnage tool. Just wondering if my baseband is downgraded or not.

Settings/About-> modemfirmware = 02.28.00 = version 2.2

im using a mac and i have quickpwn 2.1

i had 2.2 and wanted jailbreak back...i plugged it into quickpwn and it recognized my iphone 3g right away and i proceeded it act like it was 2.1 and i wanted to jailbreak.. i put it into recovery mode and and it uploaded my 2.1 jailbreaken software easily by itself

i have 2.2 and now it has cydia and installer....i used quickpwn 2.1 and everything is the same its weird

so are we completely hopeless to unlock or is there still some hope

The Dev-Team do work fast, and preliminary results are already in.
In their latest blog they mention a new way to hack the upgrade to 2.2,
and go on saying that the baseband problem should be resulted in the "near future"
after they perform enough testing....

http://blog.iphone-dev.org/

some of us here in Israel are also desperately waiting with iTouches to return to their old iPhone states...

So many jumped to upgrade to 2.2 so fast...especially when Dev Team can't unlock 2.1 yet????

We know we were stupid.
I didn't expect 2.2 to stop my SIM Adapter working though. We live and learn.
But I doubt we are that high on the Dev Teams priority list.

Yes, I was really stupid to update it. Aftre that I've tried using this method, but no luck. Baseband downgrade is impossible right now.

The problem is, after I restored my iphone 3g, I couldn't activate my iphone again, so only emergency call, which means one step back instead of returning to the initial setting.

I spent one day to go back at least to the "ipod touch" status, but it was not possible. Finally with QuickPWN I was able to activate, so right now I have an iPhone 3G with Cydia and Installer, and 2.2 firmware with the most actual basband, which is 2.28.00

I think we have to wait for an another proxy sim solution. This baseband will take forever to be unlocked I suppose.

Right now, my aim is to sell this iPhone as soon as possible, and buy an official sim unlocked iPhone from Italy, Turkey or Belgium...

I followed the instructions and it doesn't downgrade the baseband... It's back to 2.1 and unlocked, but still has the 2.28.00

I think we have to wait for a way to go back to the baseband, Right now, it is not possible.

My question is, are we going to see another proxy-sim update?

HELP--How to you downgrade the iphone 2.2 baseband? I have downloaded the back to 2.1 but need a lower baseband!! What do I do?

Right now, there is no way of going back to the old baseband. I know it sucks, but we can only wait....

It's our own fault - guess we shouldn't have been so impatient. You can now upgrade tp 2.2 without upgrading the BaseBand. Unfortunately there is no way to downgrade at the moment an das of yet the SIM adapters don't work. I wonder which will come first!

I downloaded the ZiPhone software from here

http://www.4shared.com/get/66726207/2b0bc301/_En__ZiPhone_patched_by_kIREmK_040504_G.htm

There are a lot of folks who need help getting back our Iphones- Hopefully, someone will find a way to get the proxy sim problem fixed. I miss my iphone already. Haven't seen any solutions that work on the web as of yet.

I made same mistake and upgraded I phone and now my turbosim does not work, by reading this discussion, I came to conclusion that there is no point since i will not be able to downgrade base board and my turbosim will not work, if any one know the go around please post here

Is anyone know when can run any software to downgrade baseband and do turbo sim works again ?

Yes I managed to update to 2.2 I have a UK 3G iphone which I was using in Thailand with a turbosim and it came up with 'No service' message......my only excuse is pure ignorance :P

I'm gutted but it still works with the O2 sim card, which I suppose is a blessing, but I really can't afford to pay thier ridiculous roaming charges (I'm not as rich as apple!!!) so I am hoping some clever peps out there come out with a turbosim that will work with 2.2 and trust me after that I will never even keep the bloody thing in the same room as a computer with itunes on it let alone update it!!

Hmm its just put me off buying another apple product again, not a great way to treat customers who have spent alot of money!!!

Sam

please don't waste your time with this damn blog; it's fake.. rip off, works with no one. ZIPHONE isn't working...

Allright, done is done .. right now im sitting on an AT&T iphone in sweden.
When i realized that my iphone didn't find my operator i tryed to restore it in itunes, hoping that it would help. Now i have a phone that i can't even register (and use as a ipod touch).
My question though, if anybody has an idee ... would my "unregisterd" iphone be any harder to unlock if the iphone dev would come up with a solution ?
Another question is: probebly the iphone dev team will try to come up with a solution. iPhones that are sold from now on will use the 2.2 firmware and for thouse user a new hack will be necessary? I mean it probebly is of high priority?

Tor-Björn, Sweden

Hi Björn,

I've made the same mistake and lost the activation of the iphone. I tried very hard to return it back, and the I was able to jailbreak it finally.

Use QuickPWN and firmware 2.2

I made it on a Mac...

I hope another sim proxy will be available soon...

nymphe, Germany

What is the advantage of having Modem Firmware 02.11.07 instead of 02.28.00?

I thot the iphone dev team is working on Modem Firmware 01.45?

02.28.00 doesn't work with the sim prxies, like Turbo Sim or Gevey 3G...

Nice to hear! Just so I understand you correct. You jailbreaked your unregisterd 2.2 (the phone is stuck, saing the SIM ain't correct, right after you enter the PIN) with QuickPWN so that you can use it as a ipod touch. The network connection is still lost, do I understand you right?
That would be a nice improvment though, untill someone hopefully solves the baseband.

Tor-Björn

I bought my iphone from a guy in craigslist in USA. It was activated so I was able to use it as an ipod touch.

After that I went back to Germany, I bought a Gevey 3g sim proxy, I was able to use my provider. (E-plus)

Friday night I updated it through iTunes, I never thought the simproxy won't work, but after I made all of my settings, I realized that it won't work with my sim proxy. It awsn't jailbroken until then.

So, I came to this web site, I learned that there was a baseband update which screwed me, and I tried to make a downgrade. I had my girlfriends macbook with Vista on it, so I tried this modified ziPhone, but without luck.

With trying restoring the firmware I lost my activation too. So this should be your status right now.

After that I tried everything, but I couldn't install jailbroken 2.1. Actually, I couldn't install unaltered 2.1 firmware, neither.

Couple of hours later, I gave up and installed 2.2 for the 4th time with looking at the emergency call option..

As a final method, I used QuickPWN, so it hacked the 2.2 firmware, put Cydia and Installer in it, removed the activation and put it into the iPhone.

Finally, iTunes restored everything back to my iphone. What I can do now is only waiting for an another sim proxy solution. I don't think dev team can break the sim lock soon. They are still trying to hack the sim lock of the old firmware. The new one? It will definetely take a very very long time.

I hope it will work for you. I am following this page, if you have problems, just send a post here.

nymphe

Thanks, I will try that right now. Only difference is that I have tryed to jailbreak my phone with pwnagetool 2.2.1 without any luck. It is still unactivated.
Get back with the result!

"Couple of hours later, I gave up and installed 2.2 for the 4th time with looking at the emergency call option.."

How do you install the 2.2 after restoring the iPhone? Since mine is unactive, the update to 2.2 don't even show in itunes?

hi,

First of all, you have to download 2.2 ipsw file from apple. You can find the link very easily if you google.

After that, you have to enter your iphone in recovery mode (or dfu mode by pressing both of the buttons for 10 seconds and then relasing the power button, and keep the home button 10 seconds more.

In order to be able to choose 2.2 fimrware, you have to click on Restore button in iTunes with option (on a mac) or shift (on a pc)- Then it will ask the location of the ipsw file you've downloaded.

nymphe

Tanks alot, that worked just fine.

At least know I can enjoy the calander and the other programs at home with wifi connection!

Do you know if the at&t iphone will work with european operators that have the iphone.
Then in worst case senario I could always switch to Telia (Swedish operator that have the iphone) if a new proxy-sim or a bandbase downgrade doesn't show up.

I am happy to hear that.

I don't think so. I haven't tried it, yet, but there is a sim lock for AT&T. They don't put other phones in it.

I'll try with my Turkcell card at home. Turkcell is one of the providers in Turkey which are selling official iPhones. (with ridiculous prices of course)

But I don't give 1% chance for it... As I said earlier, I am desperately waiting for the sim proxy update.

nymphe
(still in Germany, but at work, there is a proxy which sets US flag:)

Guess the pwnagetool 2.2.1 installed the 2.2 firmware without register it, because i didn't have to restore it to 2.2.
QuickPWN 2.2 however did the job! Again, thanks alot and hopefully someone else will get to use this information!

Tor-Björn

There are no way to downgrade modem firmware. Its stay on 02.28.00 and ***SIM can't work, as hope so, yet.

So this is nothing!

There is one way to get it working again only for US though.

Break your iphone to a point of no return, won't boot or can't restore.
bring it to apple store for a exchange,
now pray and hope that the replacement still has 2.1 firmware on it,
and a very good chance of that happening, since most exchange iphone
are not brand new so of speak.

Of course, if you get a replacement with a 2.2 firmware, well what can I say :D

I have tried all firmwares 1.1.4, 2.0, 2.0.1, 2.0.2, 2.1 & now 2.2 but cant rid of NO SERVICE error. I did jailbroken with winpwn (iclarified)and then tried custom firmwares without checking off youtube activate option and activate iphone option, but it didnt work either. lastly I tried downgrade baseband with Kiphone GUI but still no service. Its being 15 days now Iam trying hard to get the service but Iam reallyt pissed off.!!
Please halp me out guys..!!!!

dow do i install the software ZiPhone patched by kIREmK (Pls. read this comment).
PwnageTool 2.2., on a mac?????

unfortunately, tehere is no way installing ziPhone on a mac. If you can, use boot camp.

nymphe

Excuse me, didn't we all pay for these phones? Shouldn't we be allowed to do whatever we desire with the phone (at our own risk)? Apple and AT&T can shove this thing up their asses, I'm going NOKIA.

http://rebelsimcard.com/virtu/blog/?p=13

according to this blog entry, rebel sim functions with the 2.2 firmware, but without 3g. I don't need 3g internet, I want to be able to use my iphone as a phone..

can someone test it, whether rebel sim works?

nymphe

Hehe, see you out searching for a solution as well.
Feels good not beeing alone =)
This I must say is the best news I've got since friday afternoon! Think I wait a couple a days and read some more though..

Tor-Björn

This could be something:

http://rebelsimcard.com/virtu/index.php?page=shop.product_details&flypage=flypage.tpl&product_id=154&category_id=36&option=com_virtuemart&Itemid=1

It sounds like they are pretty confident that the will succeed with the full unlock of the new BB so you want to upgrade.

Tor-Björn

I just read a post with a guy i portugal that use rebel simcard with the 2.2
Sounded like he had no problem at all. Posted to see if he has 3G as well.

Post back

Tor-Björn

:) We are not alone Björn :)

Well, as I mentioned before, I don't need the speed of 3g internet (yet). Actually my mobile service provider doesn't have 3g internet.

If the rebel sim works good, then it makes sense to use it. But it is not cheap. It is something you need to pay every time apple makes an update. Therefore iphone-dev-team are right, those sim proxies can not be trusted. As I said earlier, I am going to sell this thing as soon as possible, but first, I need a working phone...

Keep on feeding the news... We need more confirmations about this.

nymphe

I download the file' open it with power archiver but when I start the "start" file it is open a dos window that says "searching for iphone"
there is no any window as shown on the instructions???
after it is find my iphone it is make "dfu" and then the itunes opened and ask me to do a restore to the phone.
Please people what should I do? how can I run the ZiPhone patched that will open a window as describe here?

thanks

....you guys are not alone....xD

I have a same fu*king problem. And form what i had found there is no way to downgrade from 2.2 baseband to any lower one....so.....now i have "iTouch"...good thing is i didn't sell my other phone - Nokia 3310 (ooouuuuuu yeaaaaa...old school xD). So i will be patient and wait for some solution for this problem. Hope dev team will think of something.

Cheers

I have tested 4 of Rebel sim cards on 2 iphones and can assure you they don't work.

I even updated them to the latest rebel firmware.

All that happens is the signal comes on for about 4 seconds then says no service. It's just another way of them getting money out of you to by a programmer of them.

It's a waiting game until either a baseband downgrade or a new any network device comes out.

Fingers crossed and lets hope its soon.

by the way any one who wants to get there iphone out of recovery mode just

1. switch the phone off by holding power and home page
2.download and run quickpwn.
3. power iphone by howing powerbuton 2 secs
4 quickpwn will detect the phone and restart as normal. There is no need to do anything else . so shut down quickpwn

Thank you UK, for your informative post.

Apperantly we have to win this waiting game....

nymphe

Looking for a despreate solution, I found this from AnySim:
http://www.ukphoneshop.com/news/mobile-phone-unlocking/iphone-3g-22-unlock/1034/

IMO i think what they mean by 2.2 unlock is for the 1st Gen iphone not for the 3G, but if anyone can confirm this or test it out it would be of great help.

Looks like these guys are on to it. HTey do not show the baseband version however so guess it could be fake..

http://www.youtube.com/watch?v=jRtpTaQ75zo&eurl=http://www.i-smartphone.biz/&feature=player_embedded

Even if there are no solution at this point, at least I feel like there are going to be one soon! Let's hope I'm right =)

Tor-Björn

I wrote to TheMOTT.com asking to see if their adapter works with the new baseband, and this is what they replied:

"Hi, We will have an update unlock adapter within 1wks time to support the Stock Baseband update and you will see it verified with a video to prove that its working.

Best Wishes,

TheMott.com"

we might just be in luck next week... or maybe not.

Hi everybody. After struggling for hours to downgrade my iphone from version 2.2 to version 2.1 I finally found the real way to do it.

I made a small step by step video to walk you through the process. All the links to download the files you will need are also in the link below. Hope it helps everybody. Thanks.

check this:http://www.ukphoneshop.com/news/mobile-phone-unlocking/any-network-release-unlocking-for-iphone-3g-22-with-baseband-update/1035/
they said that they unlocked 3g 2.2 baseband with v3 simcard!!

We Dont need a downgrade, with a downgrade all we are doing is backtracking our phones, therefore, no new technology will be available for us, what we do need is a new sim proxy, so whipp out the cash and stop being chep and buying 18 dollar sim unlockers, pay the Extra 10 for a AnyNetwork sim.

(dont mean to sound rude, but its true, neither Gevey or RebelSim have cared, dont even mention Turbo Sim, their wating on what we're waiting, to copy it off, so lets just bombared AnyNetwork with email letting them know we want a SIM THAT WORKS SO GET US ONE AND WE'LL PAY THE PRICE).
Jeff.

.....any solutions guys?!?!?

I didn't find nothing real. :(

FriX

great news...

hope the price is not too high, though...

nymphe

I am new to the mac world and never used an iphone (Always been A Nokia guy). So got an iphone and what a fu* up.! I pay for the phone and they control where I could use it. Again I was stupid.

Back to nokia

Hi guys,
I just wanted to know if there exists already a solution for our problem? What about the guys from dev-team? I searched in different forums but it seems that nobody has a solution ready... But I don't want to use my iPhone 3G just as an iPod Touch!!!
What do you think, when will we be able to use our iPhones again?
Nicholas

....maybe there is hope for us....

I see ebay has got the turbo sim's for 2.2 now!

... but I don't want to buy a new turbo-sim! no software solution out there?

Just placed a order for the any-network v3 proxy-sim.
This is the only solution to unlock the iphone 2.2 with upgraded baseband at this time!

Tor-Björn

Yes...there is NEW turbosim for 2.2 because old one doesn't work. Hm...i don't know about that...

FriX

Hi Björn,

How much did you pay for the proxy sim? I am waiting for your comments, too :)

nymphe

Nouveau fimware pour la rebelle sim card..

QQ sais si sa marche ???

http://rebelsimcard.com/virtu/

http://rebelsimcard.com/virtu/blog/

Sébiichou

For what I understand, neither turbosim nor rebelsimcard works with 2.2
The any-network v3 cost £29.90 if you buy one or two. With shipment it total up to £36.90

Tor-Björn

...ok...i've also ordered one v3 card from any-network.... It costs £36.90 but small price if this will bring my iphone to life... So...i will wait and report.

FriX

those cards are really expensive...

I think I am going to wait until price drops. I don't want to give 20-40 EUR each time Apple updates this.

nymphe

I also ordered the new V3 card from any-network. for me, 37 pounds is a small price to pay for a fully functional 3G iphone.
the pictures in the any-network site show that it works with the orange network, which is what we have here in israel.
please keep up posted if anyone got it and saw whether it works. mine should probably take about a week to mail to here.
can't wait....

That's the wrong file you need to hunt down the proper file. The .exe needs to be an icon of a orange ipod. So hunt for has many "ZiPhone patched by kIREmK" has you can. It is the right GUI. It did take me a few hours to find this.

Google this, there are loads of links

ZiPhone patched by kIREmK 04.05.04_G

Do you think that if downgrading the iPhone 3G's baseband was this easy, the Dev-Team would know? The Dev-Team are the only ones who know how to downgrade the baseband. KiPhone doesn't even work with 2.x firmwares. If you wanted to be unlocked, you shouldn't have upgraded to 2.2. Stupid losers.

Alot of people did not know because they woke up and saw there was an update available. There were no warnings, but luckly..some of else have the cash to walk out and buy a new iphone with the old firmware.

I"m really not sure what rock you crawled out from, but don't call people losers when you don't know their circumstances. Your probably some kid living at home, picking his nose, and asking your parents for your allowance.

Everyone doesn't have to keep on say that after 2.2 update can't get service.
Can jailbreak 3g phone with 2.2 OS.
Phone function work work unless a solution comes out soon.

1. Can jailbreak 2.2, even u updated via itunes.

2. For phone function (due to baseband upgrade)

- wait for the new sims
or
- wait for a new app to downgrade baseband.

Period, I hope to see any if the solutions posted, not the same old problems we all know.

I tried this i hope it works....

http://www.uploading.com/files/VMT6DJRB/[En]_ZiPhone_patched_by_kIREmK_04.05.04_G.rar.html

Works a treat....

My iPhone was basically normal! It had only been jailbroken a while, I updated to 2.2, and it worked, but i got a no service error, now I get a No sim error, and its stuck in DFU mode.... wtf?

Hey ALL,

I have found a supplier of Turbo SIM cards that work 100% with the 2.2 update!! SERIOUSLY!! I have the pictures to prove it!! I have tried it out over 20 times with T-Mobile and they work like a charm!! Contact me at phoneunlockdoc at yahoo dot com.

Dear All,
i am also one of you who are using their Iphone 3g as Itouch. update me if you gets any solution to overcome with this problem.my id is anurag.g@hcl.in

Yes, the new sim is out.

1. 3G iphone updated to 2.2 via itunes

2. Jail broke 2.2 with qpwn.

3. No service= expensive ipod

4. Had no service until today 12/1...

5. Found the new sim that works for 2.2 update + baseband update

However, after 2.2 update (including baseband update) u have to jail break it with qpwn 2.2.

The reception is so full !!!

Thanks to the brain'rs of the iphone.
