I have a huge problem with my iPhone 3GS: - Orange FR Sim Lock - New BR - BB 05.14.02 (after Redsn0w Ipad BB Downgrade)
The whole restoring process of sn0wbreeze CFW 6.1.2 (hacktivated) works properly without any iTunes failure messages. After the installation, iTunes says that the process is finished successfully. Furthermore, the evasi0n Jailbreak in the end of the installation is successful.
The Problem: My iPhone is restarting all the time when it is connected to the computer. This stuck is starting directly after the successful installation process. The Apple Logo appears for around 20 seconds to one minute, then the display is getting dark (but still on) for 20 seconds to one minute, apple logo, dark,.. When the iPhone is not connected, the loop stops after some time and the display stays black. I also tried to restore iOS 4.1 CFW and 4.1 Original Firmware and the problem is the same. I can't turn off the phone by power button and my only chance to enter DFU Mode is the redsn0w "DFU IPSW" function. Nevertheless, I am still able to enter Recovery Mode using the power button.
The Past: I've tried out iPad BB, Original Apple iOS 6.x and 4.x FW, downgrading to iPad BB with redsn0w, downgrading from iPad BB to 05.14.02 with redsn0w.
Besides I deleted once the "com.apple.SystemPowerProfileDefaults.plist" located in /System/Library/CoreServices/powerd.bundle/ after saving a copy to my computer because I read somewhere that it might help.
I have the chance to change data in the system directory of my iphone using "iExplorer". I already have replaced the "com.apple.SystemPowerProfileDefaults.plist" file with the one I have saved before.
And Now? I don't know what to do anymore to solve the problem. I have read that a short-circuit of the iPhone battery might help. As I can't break much anymore, I even think about it. Do you have a recommendation for me, how to make my iPhone usable again?
