[HTC One X] AngelDeath:
Greets all, I just rooted my HOX that was returned to me, and I unlocked the bootloader and rooted it. So I decided to look at the build prop just to be curious, and the Bold section caught my eye.

Again I am just trying to help, it maybe something, it maybe nothing, but This rom is really starting to look a bit odd with some of the things in the build prop.

Again, this is untouched, unmodified build prop to the ROM: 2.17.1900.1 they installed back onto my Unbranded International HOX after they repaired it.

The Main Key here is, My HOX is an International Quad Core, not a US version, on top of this it has a CID of HTC__001, it has an HBoot version of 1.12, it was sent to a US repair center in Houston Texas for repair, they "Locked" my bootloader, and installed this rom on my phone, could this be a clue on possibly not needing "S-OFF" to flash roms from another region?
