How To Install TWRP Recovery on HTC One M9

HTC One M9 TWRP Recovery

Update (July 28, 2015): Well, this post is being updated with the latest version of TWRP recovery, which solves many, many things and provide answer to many, many things. Ok, not that many things, but still, be sure to install TWRP v2.8.7.0 linked below. And, even more important! once you install the TWRP recovery, don’t mount the system as read-write. Keep it as read-only. From TWRP v2.8.7.0 and higher, TWRP doesn’t mount system as read-write if it detects that it was never mounted. It gives you opportunity to take a backup of system, so, grab it with both hands. Create a backup now! And then go on and mount system as read-write, and then whatever you wanted to, including flashing SuperSU file to gain root access. But be sure to create backup before mounting system as read-write.

If you have understood what’s said in this paragraph, then only go ahead to TWRP recovery installation and take care to create backup before mounting the system as read-write or installing any zip file.
