OnePlus One owners (well, those who’ve managed to get their hands on a OnePlus One) are necessarily a bit more prone to living on the edge than the typical Android user, and for them, good news! There’s an official alpha release of an Android 5.0 Lollipop ROM available for OPO users today. Of course, as an alpha, it’s a bit buggy, but it is available now.
We’ve linked to the instructions below (from the OnePlus One forums), but it’s important to stress this is very much an alpha, with OPO saying the following:
It’s so early, in fact, that this build contains no extras beyond the stock features of AOSP Lollipop. It’s the base that we will continue to build upon, improve, and customize as we stabilize core functionalities on the latest firmware updates. As we look towards the official ROM release in the near future, we will keep to our promise and deliver an experience that is customizable, yet bloat-free with stock-Android-like simplicity by default; we wouldn’t ask you to settle for anything less.
Issues are said to include unstable WiFi, hit and miss camera performance, crashes and problems with capacitive keys working properly. On the plus side, though, OnePlus’ warranty covers flashing custom ROMs onto the OnePlus One, so if you manage to screw something up, you’re still covered there. As with all things though, be careful when trying out experimental ROMs such as this.
If you’re keen to give it a go, we’ve repeated the instructions here, or you can go to the OnePlus source link below for further information.
Download Oneplus_community.zip (you can find the link below) and copy the file to your phone. On a Mac, you can use Android File Transfer. If you have TWRP installed, you should see a TWRP folder, and that’s where you want to place the zip.
Boot into TWRP recovery. You can do this on your OPO by holding both the volume down and power buttons.
Once you are in the recovery interface, the first thing you want to do is go to Wipe and do a factory reset to clean your data, cache, and Dalvik. Note that you will lose all of your files so make sure everything is backed up before continuing.
After the wipe, go to install and find the zip you copied to your device and confirm flash. This should flash the ROM to your device.
After flash is complete. Clear your cache again. If you have GApps, install it now. Reboot your phone.
You should now be booted into the new ROM. Enjoy.
