Now that you’ve landed here, to install TWRP recovery your HTC Bolt, or the HTC 10 Evo, as it’s known outside USA, we can assume that you are looking to either root it or flash custom ROMs or mods on it. Well, welcome to the world of Android modding.

Make sure that that you must have unlocked your bootloader of your device.

Flashing a custom Recovery enables you to do a whole range of things that HTC generally does not want people to do.

This includes removing the stock ROM from the OEM and flashing (or installing) a custom ROM. A custom ROM is a modified version of the Android OS made by developers or by other people who do it for a hobby.

Now that we’ve established what a ROM is, let’s get back to a custom Recovery. TWRP is not your standard run of the mill recovery. Carrying a range of functions, the TWRP recovery is a powerful tool that essentially let’s you install, backup or restore ROMs. Alongside that, you can use the in built file manager, and carry out other basic tasks and tweaking.
