HTC One (M8) Tastes Android 7.1 Nougat Update, Here’s How to Install CyanogenMod 14.1 Cutom ROM

Although it’s more than two years old, HTC One (M8) is still a pretty capable device. It is no longer planned for upgrades by HTC, and there’s also that news about Qualcomm not releasing updated graphic drivers for Snapdragon 801-based devices, keeping them from getting Android Nougat. At the moment, the phone can only run Android Marshmallow-based official ROM.

Nevertheless, people behind CyanogenMod managed to bring Nougat 7.1 to the One (M8) via CyanogenMod 14.1 custom ROM. The ROM is still in Alpha build, with some things not working and some working not exactly as intended. Be careful, since flashing can brick the device, with other problems also being possible to appear. As we already said, the custom ROM is still in Alpha version and contains some known bugs. Here’s the list of what’s working and list of known bugs:

Working: System stays alive, Wifi, Phone, Data, Sound, Camera, GPS.

Known bugs: Assisted GPS – (GPS works, but AGPS does not), It takes a while for the SIM to be recognized.

[Disclaimer: flashing unofficial ROMs is a very technical procedure and should only be performed by a person with deep knowledge of rooting and manually installing Android software. If the procedure is not done properly, it can lead to the smartphone getting bricked, even getting permanently irreparable. Mobipicker.com can’t be held responsible for any potential damage the installing procedure might cause on the device. Proceed with caution.]

If you plan on bringing the latest CyanogenMod 14.1 to your HTC One (M8) device, here’s how to do it.

Firstly, you must download the following files:

HTC One (M8) Android v7.1 Nougat-based CyanogenMod [unofficial] CM 14.1 custom ROM – Download link

USB Driver – Download Link

Google Apps – Download Link

Before commencing installation procedure, make sure you check out prerequisites.

• Make sure the device is rooted before starting ROM installation.
• Make sure the USB driver is installed in the PC or else your device will not be recognized by the computer.
• Make sure your device has more than 80 percent battery, or else there is a chance of the phone getting bricked if the installation procedure is interrupted before finished.
• This CyanogenMod CM 14.1 Android v7.1 Nougat custom ROM series has to be installed on HTC One (M8) GSM model only, if tried on other devices, it might brick them [to check your device model: Go to Settings >> About phone >> model number].
• Though installing a 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 the warranty by flashing the device with stock-ROM].
• Installation of custom ROM requires clearing memory in the phone, so make sure you back all the data by installing Clockwork Mod (CWM) Recovery/ TWRP in the smartphone.
