I want to install a new ROM (HTC_One_X-_MaximusHD_21.0.0.zip), and (Kernel+Flasher+21.0.0.zip). I tried flashing the kernel and ROM but my phone won't boot after over 10 mins, so I restored backup.
I want to Install ROM (HTC_One_X-_MaximusHD_21.0.0.zip) but I read in the ROM install guide that I need HBoot of 1.3x or higher to be able to install ROM successfully.
I have downloaded software update OTA but unable to install (Error: Installation Aborted).
Please I need help on how to change my Hboot to 1.3x or higher in order to install ROM.
N/B I have S-OFF and unlocked bootloader.

Thanks in advance
