Nexus 10 Gets Android 4.2.1 Jelly Bean Update with Official CyanogenMod 10.1 Nightly ROM

Nexus 10 users can finally enjoy highly stable build of official CyanogenMod 10.1 (CM10.1) nightly ROM, with due credit to the industrious CyanogenMod team. The unofficial nightly builds of CyanogenMod 10.1 ROM were rolled out earlier for the same device. The updated official CM10.1 nightly ROM brings a host of exciting features taken from original AOSP release of Android 4.2.1 Jelly Bean.

NOTE: As this is a nightly release which is still under development, it may harbour a few untested bugs or broken features such as FC errors, boot loops or boot failure. Just reinstall the stock firmware or another stable custom ROM to fix the issue. IBTimes UK will not be held liable if you damage or brick your device during or after firmware installation.
