We like remind our readers that this PACMAN Android Marshmallow ROM is an experimental version, so it might contain some bugs. Users are advised to exercise caution before going ahead with this custom ROM installation.

Prerequisites [Things to remember before installing the Custom ROM]:

  • This new PACMAN Android v6.0 Marshmallow custom ROM has to be installed only on OnePlus One aka Bacon models; if tried on other devices, it might get them bricked [To check your device model: Go to Settings >> About phone >> Model Number]
  • Make sure the device is rooted (Bootloader unlocked) before going forward. [How to unlock Bootloader]
  • Though installing this custom ROM improves the device's performance and UI experiences, it voids the company warranty, and the company will no longer be liable to provide updates in future [users can restore warranty by flashing the device with stock-ROM].
  • Installation of the custom ROM requires clearing of memory in the smartphone. So make sure to back up all the data by installing Clockwork Mod (CWM) Recovery/ TWRP.
  • Make sure you have installed USB drivers on the PC, or else the device would not be recognised by the computer.
  • Make sure your device has more than 80% battery, or else there is a chance of the smartphone getting temporarily bricked if the installation process is interrupted midway.

[Disclaimer: This procedure is very technical and should be performed by a person with sound knowledge of rooting (or manual software installation on) Android devices. If the step-by-step installation process is not followed properly, there are chances of the smartphone getting bricked or becoming permanently irreparable. IBTimes India cannot be held responsible for any damage or claims from readers if the procedure does not yield the required results or if the smartphone is bricked. Hence, users are advised to proceed with caution.]
