I posted this question in the official apple forums but it seems like all people do is just add more questions to the original inquiry rather than actually answer the question, so I'm hoping I can find the answer here. I have an Iphone 4 with ios 5.1.1. About a month ago, my iphone suffered water damage. I turned it off and nursed it back to health using the dry rice method. 2 days later I switched on my phone and it seemed like my Iphone returned to normal. 3 days ago I turned my phone off for what i'm pretty sure was the first time since I recovered it from the water damage. Iphone won't turn on without being connected to power, although it says it's on 100% battery when it does turn on. It goes to front screen and... you know the drill, activation required message. I'm almost certain it wouldn't have happened had I not turn my phone off. My phone is unusable. I have managed to bring it to DFU mode and have the option to recover if I upgrade to ios 6, however before I do it I want to make sure this is the only necessary step to take. Reason being I enjoy using ios 5 and don't want to change it. any ideas on how to rescue my iphone without upgrading the operating system? I'll appreciate any help!
