Winpwn][bootneuter] Error (21) and old problems with bb. HELP, PLEASE!!!
Hi, I'm having some problems with a new iPhone. This phone was bought by a friend and one person tried to unlock it. But I don't know how he proceded and this iPhone have some issues with the baseband (i'm think right now that he used ziphone).
Ok, the phone have some times of completely signal, but too many times of no service an, i'd seen one time of "no sim".
After donig too many things, like downgrading upgrading, erasing, writing, downgradig upgrading, my last hope was the 2.0 bootneuter and the newer baseband. But i have error 21 in bootneuter and apears that the bb has not been upgraded properly.
Uhm, the bootloader is always fine.. .
I aprecciate some help... i don't think that is a hardware problem. I'm whit this iPhone at least 1 month and tried everything.. please help-me.. I'm think in something that rewrites completely the basebando.. manually.. don't know.
