Ever upgraded your device to a firmware then you regretted later? This guide can help you resolve the problem. I’ll be downgrading my iPod touch 2G (this works on every device) from iPhone OS 3.1 BETA 7C106c to iPhone OS 3.0 7A341.
First, plug your device into your computer and open iTunes.
If you already have your device’s Restore Image (.ipsw) place it somewhere handy like your Desktop for quick access. If you don’t have it, grab yourself a copy over here.
Restore your device to the old OS (in this case, iPhone OS 3.0). Don’t unplug or do anything to your device during the restore and after unless told to. Let it finish. You will get an error, this is actually good. Don’t unplug or do anything to your device yet.
Download iRecovery (Mac or Windows).
Note: Mac users, copy the “libusb-0.1.4.dylib” file to “/usr/local/lib/“ (Apple + Shift + G) before using the executable.
Extract the zip on your desktop. Put the iRecovery executable on your desktop. Open Terminal (Apple + U). Enter the following: “cd ~/Desktop” *return* “./iRecovery -s” *return* “fsboot” *return* “exit” *return*. You can then close Terminal.
Windows users: Run the libusb installer first then run iRecovery from the iRecovery_SVN folder.
Once you’re done with iRecovery your device is safely restored to iPhone 3.0 (in this example).
WARNING: PLANET-IPHONES.COM NOR THE AUTHOR IS RESPONSIBLE FOR ANY DAMAGE DONE TO THE DEVICE.
HELP!!: Windows users: Run the libusb installer first (this step block the usbs) and i can’t run the next step run iRecovery from the iRecovery_SVN
has anyone tried this?
I did, on an iPod touch 2G and iPhone 3G, works like a charm and a friend of mine did it on a 3GS except he had an issue (apparently 3GS-only error) where he couldn’t reboot his phone without having to re-do the procedure.
can u please break the steps down on a mac i donnt get what to do
Need urgent help for an 3gs/4.2.1/ipad BB. I have an iphone whose bb was 05.15.05. I used the 4.2.1 fw to upgrade and then used redsn0w to update the ipad bb and jailbreak it. The phone came up with network and is working fine. However, I can find a few problems with it:
-Push doesnt work at all. I have installed push doctor **mod edit: please don’t post repos containing warez**
-The phone crashes a lot more times than expected.
-Applications like fontswap when opened, they crash and the screen comes back to the lockscreen.
I read a few posts around where in it talks about downgrading the phone to 4.1 and then using tiny umbrella to kick out of the recovery mode etc.
I would like to know if that will help me fix the problems? Also I would like to know if there will be a fix for the ipad bb problems around?
Thanks for ur help!
