Install TWRP Recovery and Root HTC U Ultra

The HTC U Ultra has been in the market for a while and as expected, it now has a custom TWRP build ready to be installed. You will, of course, need to unlock the bootloader first. Once the bootloader is unlocked, you are free to install the TWRP recovery and flash away some sweet ROMs or mods and even root it. There are other custom recoveries out there too but if you’ve ever used custom recoveries you probably know the advantages TWRP offers.

This TWRP build for the HTC U Ultra comes from XDA developer  Captain_Throwback. You can expect some minor bugs here and there which shall be ironed out in time. Currently, the only known bug is that you can’t Reboot to recovery from the Reboot menu of the recovery. The only possible reboot is rebooting to the system.

Warning: Rooting and installing custom recoveries are risky procedures, however simple they seem like. If things don’t pan out as planned you might end up bricking your device. It’s very much possible to bring it back up by flashing the stock firmware by HTC again. In any case, DroidViews or the developer don’t take any responsibility if you choose to install this recovery on your device. Thus, can not be held responsible. The procedure described below voids your warranty.

Before we go ahead and show you how to root your HTC U Ultra, there’s something you should consider. Rooting with SuperSU 2.79 shouldn’t, in theory, trip the SafetyNet meaning you should still be able to download and use NetFlix, Snapchat, Android Pay and any other such apps. That is as long as you don’t install any mods or make any changes to the system partition, including removing system apps. If you want to do all of that, you should root your HTC U Ultra using the MagiskSU instead.
