How to install Android Marshmallow on HTC One (M8) via Blues custom ROM

Custom ROM developer Blues has released the Android Marshmallow-based firmware to HTC One (M8).

HTC device owners who are bored with Sense UI and want to explore different interface on One M8 can try installing the Blues custom ROM.

Blues firmware offers visually appealing interface with coloured Navbar, network traffic monitor, performance tweaks and numerous other value-added features.

Prerequisites (things to remember before installing Custom ROM)

• Though installing custom ROM improves the device's performance and UI experiences, it makes the company warranty void; the company will no longer be liable to provide updates in future [users can restore warranty by flashing the device with stock-ROM].

• Make sure the device is rooted before going ahead with custom ROM installation.

• Installation of custom ROM requires clearing memory in the phone, so make sure to back all the data by installing Clockwork Mod (CWM) Recovery/TWRP in the smartphone.

• Make sure USB driver is installed in the PC or else your device (HTC One M8) will not be recognised by the computer.

• Make sure your device has more than 80% battery.
