Nexus 4 Gets Android 4.2.2 Jelly Bean Update via CyanogenMod 10.1 M3 ROM [How to Install] .

Nexus 4 users can now enjoy the latest custom build of Android 4.2.2 (Jelly Bean) update, thanks to the release of CyanogenMod 10.1 Milestone 3 (CM10.1 M3) ROM. The latest CM10.1 M3 release brings a host of bug-fixes and several new features over its previous iteration.

It is reportedly the most stable variant of all the nightly builds released since CM10.1 M2 release. The third iteration of CyanogenMod 10.1 Milestone (M3) release promises to offer improved stability, better Google services, enhanced keyboard functionality and many such optimisations. As this is a custom release, the firmware installation requires a custom recovery tool such as ClockworkMod (CWM) or TWRP to be installed on the handset.

  • CyanogenMod 10.1 M3 ROM and the instructions provided in this guide are meant for the LG Nexus 4 model only. It will not work on any other device. Verify the device's model number by navigating to Settings > About Phone.
  • Verify if correct USB drivers are installed for the phone on computer (download LG Nexus 4 USB drivers).

  • Make sure the device has at least 85 percent battery charge to prevent unexpected device shutdown (due to battery drain) during firmware installation.
  • The phone will not be recognised by Samsung KIES after installing this ROM, as it is a custom firmware.
  • Do a Dalvik Cache Wipe before continuing from recovery mode.
