One of the risks involved with unlocking today’s HTC devices is that despite your right to hack your device, unlocking the bootloader using HTC’s method involves effectively losing your warranty. This can cause a number of problems. The biggest of which is if the phone has a legitimate problem, HTC may not replace it even if it’s a factory defect. Users can sometimes revert the phone to stock and get a replacement, but often it won’t work.
AT&T and Rogers HTC One X owners can get around this little problem with a tutorial written by XDA Senior Member 18th.abn that doesn’t go through HTCDev. The process is a little complicated. However, if you don’t want HTC to know you’re unlocking the bootloader, it’s the only way.
Users are required to download spoofed partitions and push them to the One X. Next, users push a modified unlock code through the bootloader. This will unlock the bootloader without dealing with HTCDev at all. 18th.abn does say that there’s a script in the works, but until it’s completed users will have to do all this by hand. Originally created for the AT&T One X, support for the Rogers variant was added by XDA Senior Member niceppl.
