Popular ROM developer community AICP (Android Ice Cold Project) has released v6.0.1 Marshmallow based custom firmware to the OnePlus One.

It is around 285MB in size and comes with Doze power saving feature, new security boot system of Android Marshmallow, and also numerous value-added options to enhance user-experience on the 2014 flagship smartphone.

Prerequisites [Things to remember before installing Custom ROM]:

  • This new AICP Android 6.0.1 Marshmallow custom ROM has to be installed only on OnePlus One aka Bacon models only; if tried on other devices, it might brick them [To check your device model: Go to Settings >> About phone >> Model Number]
  • Make sure the device is rooted (Bootloader unlocked) before going ahead. [How to unlock Bootloader]
  • Though installing custom ROM improves the device's performance and UI experiences, it makes the company warranty void and will no longer be liable to provide updates in future [users can restore warranty by flashing the device with stock-ROM].
  • 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.
  • Make sure you have installed USB drivers on the PC, or else the device will not be recognised by the computer.
  • Make sure your device has more than 80 percent battery, or else there are chances of the smartphone getting temporarily bricked if the installation process is interrupted mid-way.

If the step-by-step installation process is not followed properly, there are chances of the smartphone getting bricked or being 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.]
