Is it possible to reset phone motherboard?
Hi, I bought an iPhone 4 (gsm) believing that it had a battery issue. Turns out it had been jb using greenpoison, I just want the original iOS back. If I put it into recovery mode or dfu mode iTunes detects it, but won't restore it. I have tried other cables, other computers but still get error 21, 1601, 1602 or 3194. Even after editing host file & turning off firewall and anti virus software.
My question is this: Is there a reset button/switch on the motherboard itself? If so, where is it & what is the best way to use it? Thanks to anyone who can help
Is this a good question?
