iPhone 3GS 3.1.2 won't start
Hi, I have an iPhone 3GS (OS 3.1.2) that was jailbroken about 6months ago using BlackRa1n.
I have been using it ever since without any problems, until yesterday. Just after the recent Rock update (and also some other contents included) I did a soft-reboot through Rock (the one that automatically starts after major updates) and everything worked fine. I then wanted to do a manual reboot a couple of minutes later (after updating appulous and noticing it did not work, which I later found out to be because of the service being shutdown). The iPhone turned off normally without any problems but when I tried to start it, it just turns itself off after about 8-10seconds of start-up.
I have no real clue what might have caused this problem, and I would like to ask for different ways of managing this problem. I would obviously prefer to fix it without losing applications, contacts and all the other data (my backup is about 4months old and I currently do not have access to it). I have also tried charging it during startup, but the start still aborts.
How do I fix the phone?
Best regards, Faithless
