iOS users have to deal with DFU mode, recovery mode and iOS stuck every now and then - there is even a redsn0w WTF mode. Maybe you need to put iDevice in recovery mode because you can’t update or restore iPhone, iPad or iPod, use recovery mode to fix Apple logo screen stuck, force iPhone to restart in case of DFU mode stuck/black screen of death, etc.

Tenorshare ReiBoot is a wonderful solution to all these problems, making it possible to induce the recovery mode and DFU mode, as well as exit either in an effortless manner, in a one-click operation. If your device is already in recovery mode or DFU mode, ReiBoot will identify it accordingly, allowing you get out of both modes with the same easy one click operation.

While trying to fix an Apple iPhone 3G stuck at boot logo because of a corrupt baseband, I frequently encountered "iPhone 3G (WTF Mode)" error in redsn0w never seen before (as shown below). The older redsn0w version which worked well with this old hardware (Apple iPhone 3G) showed no solution to the problem but thankfully the newer one pointed at the right direction.
