Installing a custom recovery on the HTC One M8 smartphone is going to wipe the stock recovery and replace it with a new one that can do all the same things as the original version and then some. Most of the additional features available from a custom recovery are to help developers and people wanting to flash files. These files are often new ROMs, kernels, rooting files and so forth.

REQUIREMENTS

• You must unlock the bootloader on the HTC One M8 smartphone by visiting the HTCDev.com website if you have not done so already. You cannot install a custom recovery on this smartphone without the bootloader unlocked first.
• You need to have a computer that is running on a version of the Windows operating system to use this guide because the ADB available in our guides is the version that works on Windows. There are other versions of ADB out there for Mac and Linux but not only do you need to download the different files to set them up but you also need to follow a different set of instructions. Still, if you do use any of the other versions of ADB and you know what your commands are, you can use the TWRP file that is available in this guide to flash the custom recovery on your HTC One M8 smartphone from the Mac or Linux operating system instead.

BEFORE WE BEGIN

• You need to unlock the Developer Options menu and then enable the USB Debugging Mode before you connect the HTC One M8 smartphone to the computer with the USB cable if you have not done that already. Sometimes, people, have it locked and sometimes it is already unlocked for people.
