Developer behind Tiny Umbrella, Notcom has just released an updated version of Fixrecovery which will help you in getting out of Recovery loop once restored to iOS 4.3 on iPhone. Thought he has not yet updated TU with a recovery exit solution, he has just released a separate utility called FixRecovery for Windows and Mac OS X to do the same.
The steps are as follows.
Step 1: Once you’ve restored your device to 4.2.1 or 4.3 and have entered the ‘recovery loop’
Step 2: Close iTunes if it’s running.
Step 3: Put your iPhone in DFU mode:
Hold POWER and HOME buttons for 10 seconds.
Release Power Button while keep holding Home button for 15 Sec.
Step 4: Extract the downloaded FixRecovery zip file. You will find two exe files – fixrecovery43.exe and fixrecovery421.exe.
Step 5: That’s it you should see the activation screen shortly.
Note that this app does NOT hactivate your device. You must have a valid/official sim to activate your phone.
