I'm trying to revert my HTC One back to stock.
HBOOT - 1.44.0000
RADIO - 4A.13.3231.27
MAINVAR - 1.28.771.6
Carrier - Three UK
I cannot seem to find an RUU for my device?
I'm stuck on the Bootloader screen & unable to boot up due to "Security Warning" appearing when I try. I've figured out this is due to the fact I've got a custom ROM on my device (Google Play ARHD)... I've tried installing RUU M7 UL JB 50 HTC Europe 1.28.401.7 Radio 4A.13.3231.27 10.31.1131.05 Release 310878 Signed but I get an error on the installer saying Error 131 : Customer ID Error You are trying wrong region rom
Can anyone help me please? I'm kinda stuck here.
