I'm a very new android user, so please forgive my ignorance.
I'm using a sim unlocked AT&T M8 outside USA with a different carrier. Right now, the bootloader is Locked, CID is 11111111 and S-OFF. I've downloaded the official marshmallow RUU for the unlocked version of m8 from htc website.
I follow the install instructions until the update actually starts. Then it stops after about 10-20 seconds and shows Error 155: unknown error and enters into the recovery steps (in the RUU).
Can someone please help me out with this? I will never receive the OTA's since I'm not using an AT&T sim. So RUU is the only other option left. Thanks a lot in advance.
