Install Lollipop Based AOSP ROM on Nexus 4 and Root it

1

The Android 5.0 Lollipop OTA update is delayed to November 12, so the Nexus users have to linger around for another long week. However, this doesn’t mean that they should sit idle as many AOSP build ROMs are already making their way to the developer forums. So chances are you’ll find an AOSP based Android 5.0 ROM if you hold a device which is popular enough to draw the developer’s attention.

Nexus 4 users seems to be lucky in this case, thanks to C-o-M over at XDA for the first AOSP based Android 5.0 ROM ever. To Sweeten the pot, the developer also providing a pre-rooted ROM along with the non-rooted build but we seriously doubt anyone would go for the non-rooted build. The ROM is a preliminary build and we don’t see any major issues expect for the limited Gapps package which is currently available. Anyway, no one can stop a lollipop-hungry Nexus user, so grab the ROM from the download link below and flash it.
