It's been a little over two weeks since Google officially began rolling out v6.0 Android OS update to Nexus series device.
Even rivals HTC, Motorola, Sony, and Huawei have confirmed that they will release the firmware soon. But there is no official word from the company on when the update will be made available to the popular flagship smartphone OnePlus One.
However, an industrious XDA Developer Forum senior member, who goes by the moniker 'updateing', has reportedly tweaked AOSP (Android Open Source Project) v6.0 Marshmallow, to make it compatible to the OnePlus One.
OnePlus One owners, who don't seem to be really patient, then can go ahead and flash the custom ROM to explore the all new features of Marshmallow.
That being said, we would like to advise our readers to exercise caution as this home-made firmware has some bugs in it. The good news is that they are said to be benign and will not affect over-all functioning of the device.
Here are the few issues reported in AOSP v6.0 Marshmallow for OnePlus One:
- Stock camera does not work (users are advised to install either OppoCamera port or CameraNextMod)
- Battery drains... a little faster? (no serious issue)
- The ROM comes with one generation old Launcher-2 (Launcher3 will be added later version)
- Picture in apps are sometimes get automatically zoomed out (and distorted) and cannot be zoomed in. Is this a common problem among AOSP-based Marshmallow ROMs? I tried AOSP and CAF sources, and they both have the same issue
- Security related: SELinux is disabled. HW Crypto is not working. Software-based credentials storage
- No gestures (DT2W etc)
Prerequisites [Things to remember before installing Custom ROM]:
- This new custom ROM has to be installed on OnePlus One aka Bacon models only; if tried on other devices, they might get 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 custom ROM improves the device's performance and UI experiences, it makes the company warranty void and it 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 is a chance of the smartphone getting temporarily bricked if the installation process is interrupted mid-way.
