Manually flashing the Android 4.2.2 OTA
The Android 4.2.2 update is just rolling out to select devices. If you don’t want to wait any longer, here are the instructions to flash it manually. There are different methods available like for instance using adb sideload when you don’t have root. However I have root and I’m always flashing new OTAs from ClockworkMod, so I’m describing this method only.
You need to have the following prerequisites:
- The previous Android 4.2.1 is already running
- ClockworkMod recovery (or a similar custom recovery) is already on your device
- A computer with the adb tool available (I assume you have this already)
- USB debugging is enabled on your device
If you have modified your system then you can’t flash the OTA. So first make sure that you have restored any framework modifications, undo any build.prop patches, and hopefully you didn’t delete any system apps (installing new system apps is fine, just don’t modify any existing files).
Now download the update ZIP for your device:
Galaxy Nexus GSM:
Nexus 7 WiFi:
Copy it to your SD card:
adb push 472aafeb9fe3.signed-takju-JDQ39-from-JOP40D.472aafeb.zip /sdcard/
adb push de8b8d101614.signed-occam-JDQ39-from-JOP40D.de8b8d10.zip /sdcard/
adb push 6ece895ecb23.signed-nakasi-JDQ39-from-JOP40D.6ece895e.zip /sdcard/
adb push eaef14432ff5.signed-mantaray-JDQ39-from-JOP40D.eaef1443.zip /sdcard/
And then reboot into recovery:
adb reboot recovery
Now select ‘install zip from sdcard’, ‘choose zip from ‘sdcard’, select ’0/’ (this is the SD card for the device owner), and scroll down until you see the update ZIP. Select ‘Yes – Install’
This will take a while. When it has succeeded then select ‘Go back’ and ‘reboot system now’. The recovery will ask you to disable the stock recovery. If you don’t do this then you’ll lose your custom recovery after reboot, so choose:
Yes – Disable recovery flash
Now the recovery will ask you to fix root, so you wisely choose:
Yes – Fix root
Your system will reboot and you’ll enjoy the Android 4.2.2 experience. According to first reports on Google Plus this is now buttery smooth again!
