[Q] SIM-Unlock Issues
HTC HBoot 1.55, Bootloader Unlocked, Rumrunner S-OFFed, SIM LOCKED
Unlock sites such as 247unlock can't find an unlock code. Any solutions?
I purchased my T-mobile HTC One 32gb for use on a Canadian Wind Carrier in August, paid for an unlock code via 247unlock, worked great, used it trouble free for 4 months; everything was stock. Until November 1, when the phone received the OTA 4.3 update; worked great for one week than it bricked itself when the battery dropped under 10%, would not boot up not matter what I tried...literally tried everything.
Ended up sending it back to HTC, they repaired it free of charge, sent it back, and now it's locked again. The problem is that I can't seem to find an unlocking service that can unlock it. I am 100% that it is the same device as the Serial No. is the same but the IMEI seems to have changed, as it is different from my records. Is that unheard of?
Out of desperation; I scoured the internet, a couple websites make mention of using S-OFF to sim unlock the phone; so I unlocked the bootloader via htcdevs, and S-OFFed the phone via Rumrunner (1.55 Hboot, which only worked after I flashed it to Viper, stock wouldn't S-Off). So, where do I go now? What can I possibly do to unlock this phone?
