Verizon is the first US carrier to get the HTC One M8 on its wireless transmissions, if by a nose. Even if, it took the people at Team Win Recovery Project (TWRP) a little more to get their highly adored TWRP custom recovery onto the Verizon variant of the handset, most likely because the fact that it requires a little more effort to get around the carrier’s locks. Yet whatever the reason, it is here, and ROM devotees on Big Red will without a doubt be thankful.
To install the custom recovery on any Android Smartphone you will require an unlocked bootloader, which is not as simple as most HTC hardware (because Verizon doesn’t allow you to do these kind of changes). The current trusted method is to utilize Justin Case’s Weaksauce HTC M8 root and the Firewater S-Off tool. This seems little complex to follow, so be careful that there is a clear possibility that you can damage brick your handset and even void your guarantee all at once. If that does not matter for you, you can head over to XDA developer forums to follow the steps to install TWRP recovery with ease. Once after completion, you can install it through fastboot, ADB, or by means of this GooManager application using your Android Smartphone itself.
Here is the XDA link to find everything about the TWRP for the HTC One M8.
There are now some energizing things happening in the HTC One M8 selling scene, including a conversion of the standard GSM model into a Google Play Edition. That specific tweak likely won’t work for Verizon’s CDMA handset, however atleast one user is now taking a shot at a “clean” GPE ROM. Coincidentally, if ClockWorkMod recovery is more your pace, there is an unofficial ROM that is available as well.
