My wife tried to do the OTA update, but the phone had custom rom and the phone is now bricked.
It is relocked and s-off
I downloaded RUU_M7_UL_JB_50_BrightstarUS_WWE_1.29.1540.16.exe (Developer Edition)
and RUU_M7_UL_JB_50_BrightstarUS_WWE_1.29.1540.3.exe (Developer Edition)
However, none of them worked. It gives me error 140: bootloader version error. I know it has something about downgrading, but im not sure what to do.
its been 5 hours since Im trying to unbrick it, but unsuccessful so far.
I will greatly appreciate any solution.
here are some info of the phone.
