- This new CyanogenMod CM12 custom ROM has to be installed on the HTC One M7(GSM) model only; if tried on other devices, it might get bricked [To check your device model: Go to Settings >> About phone >> model number]
- Make sure your device has more than 80% battery, or else there is chance of smartphone getting temporarily bricked if the installation process is interrupted midway.
- Users make sure they have installed USB drivers on the PC, or else your phone (HTC One M7) smartphone will not be recognised 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.
- Though installing custom ROM improve 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].
