The Nexus 10 has been launched several weeks ago and it has already received a new OTA update that takes the device to Android 4.2.1 JOP40D firmware. Use all the instructions listed in this article and you’ll learn how to successfully flash the new update on your tablet device.
This new firmware comes with a fix for the December bug and with several improvements applied to support the HID gamepads/ joysticks via Bluetooth. The update is only 1.1MB in size and it has to be installed on a device that runs on stock Android 4.2 JOP40C, but more about this you can find in the preparation info, which is listed several line below.
This is a tutorial created for users of Nexus 10 that didn’t receive the OTA update notification to JOP40D. This is manual method that you can use to update your device to the latest Jelly Bean version. It shouldn’t be that hard to apply the update but, first, you should read these guidelines:
- Use this post only for the Google Nexus 10 tablet. Do not try to flash this update on any other Android device as you will end up bricking it.
- The Nexus 10 you’re about to update should on stock Android 4.2 JOP40C firmware. No other ROM is compatible with this OTA update. Also, your tablet shouldn’t be rooted.
- Make sure that your PC has the tablet USB drivers installed. If not, then you can get them from here.
- Enable USB debugging option from the Developers Menu.
- Don’t run any antivirus applications on your PC. This might block the tools you’ll need to update the phone.
- Use this post only if you’re an advanced Android user. If you’re a novice then you shouldn’t try this guide as you might end up bricking the phone.
- Create backups of your most important files before starting to flash the JOP40D 4.2.1 Jelly Bean ROM.
- If you cannot complete the update then you should ask for more help in comments.
Now that you know all that, move to the ‘how-to’ part of this article and you’ll flash the firmware easily using Fastboot.
How to update Nexus 10 to Android 4.2.1 JOP40D Official Firmware:
- Download the JOP40D Jelly Bean 4.2.1 OTA update zip from HERE.
- Next, download the Fastboot zip from here. Extract its zip contents to a folder named ‘fastboot’ and place it on your desktop.
- Now move the OTA update zip to the Fastboot folder and after that you should power off your Nexus 10.
- Boot it into Bootloader Mode by pressing at the same time these buttons: volume up, volume down and power. The screen will show a START text and you should change it using volume buttons to show ‘RECOVERY MODE’. Press Power to get to the next screen.
- Now you should see a red exclamation point and an Android and you should press and hold ‘power’ and while doing this, press Volume up to boot into stock recovery mode.
- Select the option that says ‘apply update from adb’ from the recovery menu.
- Connect your Nexus 10 to your PC and wait until all USB drivers are successfully installed on your PC.
- Open the ‘Fastboot’ folder. Press and hold ‘shift’ button on your PC keyboard and at the same time right-click on the folder’s white space. Choose the ‘open command window here’ option from the context menu. Command Prompt will now launch.
- Now you need to enter only two command lines to flash the firmware update. Press ‘enter’ to apply the command actions. NOTE: if you don’t know how to do this, then ask for more help in comments.
- adb devices – check to see if the Nexus 10 device ID shows up. If it does, then you can enter the next command. If it does not, then you will need to re-install the tablet usb drivers.
- adb sideload 07ac4f5d6c30.signed-mantaray-JOP40D-from-JOP40C.07ac4f5d.zip – This will send the command and when you see the 100% value, that is when the update will begin to flash on your Nexus 10.
- When the JOP40D firmware file is pushed to your tablet and installed, select ‘reboot system now’ option from the stock recovery mode.
- The Nexus 10 will now boot into normal mode and you should wait until you see the welcoming screen.
- Test the Android 4.2.1 Jelly Bean OTA update ROM and tell us in comments if you found any errors and if it is more stable than the previous ROM.
I think that these were all the instructions that you had to follow. If you can’t complete the install from your first attempt, then you should keep trying and eventually you should be able to flash all the required files. In case you still have problems with this new update, then you should wait until Google pushes the next Jelly Bean firmware.
Check to see if the December bug is fixed and tell us in comments if you found any other improved feature of this JOP40D Jelly Bean update. If you’re unsure that you can complete installing the update with this manual guide, then you should wait until Google sends the OTA update notification to your tablet device.
