Need help with tethered downgrade:
Since I upgraded my Original iPad to iOS 5,the system is very,very slow,unstable,and unusable.
I don't have any shahs backed up ,so I thought I couldn't downgrade to previous version of iOS.
But I found out that making a custom firmware of previous version of iOS and get into pwned DFU mode ,I can finish the downgrade.But the device is in DFU loop.
I tried to use redsn0w to boot tethered and it worked.It boot into an iOS version that is not currently signed and I don't have shsh for.The sleep bug can be fixed by a cydia package called"PreventSleep".
But after several times of reboot,ofcourse,I still can get out of DFU mode with redsn0w.But just the screen doesn't light up and Multitouch doesn't work.(It's not in DFU mode.Normal mode.iTunes can even sync with the device,and voiceover would work.)
So,although I can boot up to the system,I can't use it.Reboot wouldn't work and the only way to get it back is restore to modern iOS version (which is slow,and unstable.)
Can anyone tell me how to let me use previous version of iOS tetheredly?
