after my iphone started to reboot every 2 minutes randomly, i decides to restore and update it.
i downloaded the 7.0.4 ipsw through itunes and hit the update button..
when i was mid updating i got error 29:
You must login or register to view this content.
i rebooted it to retry, and it got in recovery mode so i restored and updated the phone.
now it keeps giving error 29, and is in a recovery loop
i read something about a battery change, i still have original battery do i have to replace it??
thanks in advance!!!

Moved to the iOS Questions and Help section.

Yeah mine appeared to have no OS on it either but try doing fix recovery and then exit recovery

I cant fix/kick iout of recovery, as there is currently NO WAY to install OS on the phone, every way to install/update OS results in error 29 mid updating

Take it to apple store? Setup an appointment with the genius bar.
