[LF] Iphone fixing wizard

[Paranoid]

Hi guys,

I recently bought a second hand Iphone 4s which had some errors. I assumed I could fix it since I've done some Iphone/Ipod fixing in the past. I got past two of them but now it seems it can't restore because it gets an unexpected error (-1). I browed around for a couple of days and I'm assuming this is hardware based since I already took everything apart with only the motherboard connected and then it still has the same issue. From what I've read I understand that this could be because it was jailbroken on a certain baseband and someone tried to update it to the newest firmware 6.1.3 which screwed with the baseband somehow. Of course I have no clue what else could have happened with the phone but it is in very good condition and everything else probably works except now nothing works of course ^^

I've read it could be fixed by reballing (reflowing, etc.) the baseband with an other one, together with the AND ram or something, this is not really my field of expertise. But then again, no guarantee if that might work.

So finally the question, are there any Iphone wizards out here (since this is almost a worldwide forum) who could have some insight or equipment to deal with this kind of stuff?

You would have my eternal gratitude

If not, I guess I can still sell it as-is or for parts.

Thanks muchachos! Jalapeņos for everyone!

Have you restored it in recovery mode or DFU mode? If you're trying at the screen with the itunes logo and cable I'd try to put it into dfu mode first, then do a restore.

The screen should be totally black and off while in DFU mode and nothing should be showing, but the computer will pick up the phone as long as it is properly in DFU.

If that doesn't work then try it another time or two, if that doesn't work then it is most likely an issue with the main board.

As far as reflowing or reballing the phone I've never really found it worth it to do that, I work repairing phones, although I've heard of people doing it in their oven at home on the 3gs to fix the wifi not working.

You could try it if you wanted to.
