Taiwanese company HTC is yet to release the Android 5.0 Lollipop to the 2014 flagship phone One M8. Tech-savvy users, who are impatient to wait for the official update, can try installing the new CyanogenMod based Android 5.0 Lollipop custom ROM.
This new custom ROM is developed by a XDA Developer forum's recognized senior member going by the moniker, 'noname55804'.
It is 257.3MB in size and this firmware is based on the AOSP (Android Open Source Project) 5.0 Lollipop. This is an experimental Alpha CM12 (unstable) version, so some issues are yet to be fixed.
We advise our readers go through the whole tutorial article first before going ahead with the custom ROM installation.
Prerequisites (things to remember before installing Custom ROM)
- This new CyanogenMod Android 5.0 Lollipop CM12 firmware has to be installed on the HTC One M8 only; if tried on other devices, it might get bricked [To check your device model: Go to Settings >> About phone >> model number]
- Make sure the device is rooted before going forward for custom ROM installation. [Also read: How to Root HTC One M8 with Android 4.4 KitKat via CF-Auto-Root Tool]
- Users make sure they have installed USB drivers on the PC, or else your smartphone (HTC One M8) will not be recognized by the computer.
- Installation of custom ROM requires clearing of memory in the smartphone, so make sure to back all the data by installing Clockwork Mod (CWM) Recovery/ TWRP in the smartphone.
- Make sure your device has more than 80 percent battery, or else there is chance of smartphone getting temporarily bricked if the installation process is interrupted in the mid-way.
- Though installing custom ROM improves the device's performance and UI experiences, it makes the company warranty void and they will no longer be liable to provide updates in future [users can restore warranty by flashing the device with stock-ROM].
