Nexus 10 4.2.2 Jelly Bean update

The Nexus 10 is one of the few Android devices to receive official Android 4.2 firmware out-of-the-box, soon followed by the official release of the latest Android 4.2.1 update.

Users of the flagship tablet are in for a double treat, as the Nexus device gets yet another custom ROM Android 4.2.1 update with the release of CyanogenMod 10.1 (CM10.1). The CM10.1 ROM brings a plethora of exciting feature enhancements and system-level tweaks that promise the ultimate Android experience.


The software and the instructions provided in this guide are meant for reference purpose only. IBTimes UK will not be held responsible if you damage or brick your device. Users are advised to proceed at their own risk.


  • The CM10.1 ROM and the instructions provided in this guide are applicable to the Nexus 10 model only and will not work on any other model. Verify your device's model number by navigating to Settings > About Tablet.
  • Verify that the correct USB drivers are installed for Nexus 10 on your computer. Download Samsung Nexus 10 USB drivers.
  • IBTimes UK advises users to back up apps, important data and settings to avoid risk of data loss while flashing the CM10.1 ROM on the Nexus 10 tablet. Users who have already installed a custom recovery tool such as ClockworkMod or TWRP are strongly recommended to back up data using one of these tools, as they create a complete image of the existing ROM on the device.
  • Enable USB debugging mode on your tablet by navigating to Settings > Developer Options. Nevertheless, if you are already running the device on Android 4.2, then you need to perform the following steps to enable USB debugging option:

o Go to Settings> About Phone

o Scroll down to the bottom and select Build number

o Tap "Build number" about seven times. Right after the third tap, you will see a message box indicating that you are only four taps away from being a developer. Continue tapping four more times.

o Now, navigate to Settings > Developer Options and check the USB debugging option.

  • Make sure that the phone's battery has at least 85 percent charge to prevent unexpected device shutdown (due to battery drain) while flashing the CM10.1 ROM on your Nexus 10.
  • Ensure that your device is rooted with ClockworkMod Recovery (CWM) installed on it, before proceeding with the ROM installation procedure.
