After the controversy with Cyanogen in India the OnePlus had guaranteed consumers to make an alternate ROM based on Android 5.0 Lollipop. At that time the company also assured that it will push out an alternate ROM in December 2014 which will replace the Cyanogen OS on their devices.
OnePlus has now released an alpha build of the ROM on its own forums for OnePlus One, and is available to download. In silence OnePlus had been working on its own Android 5.0 Lollipop based ROM for the OnePlus One. The ROM looks very much the same to stock Android Lollipop on Nexus devices but it has no major changes in comparison with Android Lollipop.
The ROM is available to download, but before download you have to know that this is very early build by Oneplus. Oneplus has declared it as a community preview as we saw from Google with the L preview a few months ago. Oneplus stated in its blog “It’s so early, in fact, that this build contains no extras beyond the stock features of AOSP Lollipop”.
The company has guided users to install the custom ROM with the guidance to proceed at their own risk.
1. Data roaming is on by default. Make sure to turn if off to avoid potential charges.
2. Camera and video may be unstable. This build supports 4k video, however quality may be low as we are still fine-tuning the camera
3. As always, flashing a custom ROM incurs the risk of bricking your phone. Make sure you know what you’re doing and backup everything.
5. If using the new app pinning feature in L, make sure to turn on the software keys first. Otherwise, you will have to reboot your machine.
6. On first boot, startup time will be a bit slow. Rest assured we will speed things up in the future.
7. Capacitive keys do not turn off when you enable software keys.
8. Clock crashes periodically.
9. Wi-Fi may be unstable.
