No thanks to AT&T, owners of the carrier-branded HTC One X can now unlock their phone's bootloader on the HTCdev website. The process works by altering the handset's identifier, which causes the One X to appear as a Rogers unit on HTC's servers. While the instructions should be quite simple for those with the proper knowhow, they require knowledge and proper configuration of ADB, use of a hex editor and a rooted handset. Many users have already reported success with this method, but keep in mind that AT&T might not smile on the trickery if you ever need to seek warranty repair. Naturally, all of this frustration could've been easily avoided had Ma Bell simply considered the needs of power users in the first place, but until the day comes when the carrier rights its ways, just know that eager hackers have a tendency to come out on top.
