Prerequisites (things to remember before installing Custom ROM)

  • This new Resurrection Remix Android 6.0 Marshmallow custom ROM series has to be installed on HTC One (M7) 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 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 M7) will not be recognised by the computer.
  • Make sure your device has more than 80% battery, or else there is a chance of the tablet getting temporarily bricked if the installation process is interrupted midway.
