As explained in Galaxy Nexus yakju, takju, yakjuXX mistery yakju, takju or yakjuxw are just different software profiles. So in case of yakjuxw if you do not want to stick to the updates provided by Samsung but get the AOSP fast you better switch to yakju or even takju profile (which got more updates recently).
So what’s the trick there?
Basically the important is that the hardware is the same i.e. Galaxy Nexus “maguro”. You can confirm that by checking your fingerprint.
Once you sure about your hardware you can start the update procedure. You will not need to delete or loose any of your data or apps, however it is always a good idea to take backups as many things may happen(cat falling from the roof).
Note that we need the Android SDK as a prerequisite and make sure that “platform-tools” is in your windows path.
- download the newest factory image for takju from https://developers.google.com/android/nexus/images#takju
- extract the tgz in any directory you wish.
- there you will note bootloader-maguro-….img and radio-maguro-…..img (bootloader-maguro-primelc03.img and radio-maguro-i9250xxlh1.img)
- extract image-takju-XXXXXX.zip (image-takju-jop40c.zip)
- there you will note boot.img and system.img
- Put all those 4 noted files (bootloader-maguro-primelc03.img, radio-maguro-i9250xxlh1.img, boot.img, system.img) together and open command prompt in the this directory.
- boot device in fastboot/bootloader mode (execute “adb reboot bootloader” or holdpress volume up+down+power)
fastboot flash bootloader bootloader-maguro-primelc03.img fastboot reboot-bootloader
(wait to reboot)
fastboot flash radio radio-maguro-i9250xxlh1.img fastboot reboot-bootloader
(wait to reboot)
fastboot flash boot boot.img fastboot flash system system.img fastboot reboot
- Congrats! you have now Android 4.2 with all your data safe
