My iPhone 3Gs always crash apps since a week ago. And today, it can't open anything that I need. So, I decided to recover it so I will start it over. I started with Tinyumbrella in TSS server and a 6.1.2 ipsw with my shah stitched to it. It seemed to work in the beginning, but when it started to prepair for the recovery, the phone seemed to boot normally and iTunes poped up a message showed "iTunes 無法拷貝來自 iPhone「iPhone」的診斷資訊，因為從裝置進行讀取時發生錯誤。" which roughly means "iTunes can't copy diagnostic information from iPhone "iPhone", because an error occurred when reading it" Then, the iPhone really booted up normally. But when I turn it off and on, it went into recovery mode and stuck in it. I obviously unstucked it. It repeated many times as I tried on with different cables and ports.:(
P.S. If you have any ways to fix those fxxking crashes without recovering, it would always be better.
