If you have grand plans for your HTC One X9 smartphone and would like to start flashing new ROMs and kernels, then you need to get a custom recovery image installed before you can do that. Likewise, anyone who is interested in installing root apps will know that they need to get access to the root user account that Linux kernels have before they can do that. That’s possible to do by flashing the SuperSU by Chainfire from the custom recovery image also.

Here is what one needs to install TWRP Recovery on HTC One X9 smartphones so installing SuperSU for root access and flashing new ROMs and kernels is all possible.

REQUIREMENTS

• You need to have unlocked the HTC One X9 bootloader on the smartphone before you can follow this guide to install a custom recovery image.
• You need a computer that runs on a version of the Windows operating system to use this guide because the ADB available in this guide only installs on Windows operating systems. It is possible to install ADB on other operating systems and run different commands for ADB from those too. If you plan on going down that route, you can flash the same custom recovery image file available in this guide from your other ADB as long as you have the right commands for doing it.

BEFORE WE BEGIN

• Make sure that you have the Developer Options menu on the HTC One X9 smartphone unlocked and the USB Debugging Mode enabled from the Developer Options menu so that the Android software that is running on your device allows you to make the necessary changes to it for the rooting to work.
