Link Safe

S-OFF access to your HTC One device enables you to modify and tweak your ROM without the constraints of the NAND lock enforced by S-ON. It also lets you perform actions such as changing your CID to enable you to flash ROM updates from a different region. Unfortunately, it has been

impossible to S-OFF your device if you are using bootloader 1.54, but that is no longer the case!

Rumrunner, which runs on Linux (including Live CD) or Windows, enables you to S-OFF your device as well as unlocking the bootloader and installing root. A huge number of software releases are supported on both the GSM and CDMA variants of the One. It is important that you flash the Rumrunner tool that matches your software version. When you have S-OFF, make sure you are

careful, particularly if carrying out operations that modify the hboot on your Android device. Full,

unprotected access means it’s easier for things to go wrong! Odex your.
