S2 boot hang
I've been a long time lurker but I have finally registered to ask an important question (well to me anyway)
I fixed one of my friends' LCD and got it working. It turned on and went to the lock screen, all buttons worked but I could not do anything else as there was a password. So today I returned the phone back to him and he about half an hour later he told me he could not get pass the "S" boot logo.
I don't think that I had broken anything while fixing the phone as it booted up successfully multiple times and it is a genuine lcd. So what do you guys think? From previous testing I know that I can get into recovery and download mode so do you think I should factory reset the phone? Will that fix it? From experience I know that some phones are sometimes problematic and require a factory reset after even a general repair. However, he does not have a backup of any of the data and I don't think he would like to lose any data. Is there anyway to get pass this?
I also don't know what firmware it is on nor if it is rooted.
