Halloween was a wonderful day for every Android-fanboy this time round as it was when Google released the Nexus 5 and along with it Android 4.4 KitKat. Although, for some (Galaxy Nexus owners), it wasn’t as good a day. Google officially announced that it’s Galaxy Nexus (both GSM and Verizon variants) would not receive any Android 4.4 KitKat goodness. To put it in another way, the Galaxy Nexuses will be stuck on Android 4.3 for eternity; ..and then the good Lord said, “let there be XDA”.
According to XDA Developers, the following AOSP ROM is quite stable (it is!) with the exception of a few isolated issues like animation and graphical glitches (did not bother us much) which will be fixed in the upcoming releases.
Pre-requisites to flashing this ROM
- Back up data and settings using a recommended custom recovery tool, like ClockworkMod (CWM) or TWRP, as it creates a complete image of the existing phone setup.
- Ensure USB debugging mode is enabled on the phone, by navigating to Settings > Developer Options (if you don’t see Developer Options, follow this pastie -> http://bit.ly/1h0xTLg)
- You must be rooted on your current firmware before updating and have a custom recovery installed. We suggest using ClockworkMod recovery.
