iPhone 3GS old bootrom error 29

my iphone is old bootrom and the problem with him that i think he doesn't take charge, i can't check it because when i turn on the iphone he gets into recovery mode, but when i plug the iphone to the computer i'm getting error 29 while trying to restore. i guess that the battery was changed and that it doesn't have the original battery.

which battery will be ok for iphone 3gs old bootrom so that i will be able to skip error 29 ? give me please APN.



after replacing APN 616-0435 with APN 616-0431 battery i'm getting now with both batteries "Error -1" .

i think that it is because that battery doesn't take charge, maybe the port is broken ?

You need to put your phone in DFU-mode and than restore.

First connect USB, then hold home and power button together, after about 7 seconds the phone will turn off, keep holding home and power for another 3 seconds, now release the power button while holding the home button for another 10 seconds.

The phone should be off with a completely darkscreen, itunes should give a message that your phone is in recovery-mode and should be restored. You can now restore your phone by hitting restore or you can download the IPSW firmware and select it manual by holding ALT(mac) or SHIFT(win) and click on restore.

IPSW firmware can be downloaded from here:
