Until today my Nexus 10 was running Android 4.4.2 (stock firmware from Google). I couldn't install the OTA update to 4.4.4 because I had installed a custom recovery (TWRP) in order to root the device. So today I decided to reinstall the stock recovery and install the update... But the installation failed. The tablet was able to reboot, but it showed that is was still running Android 4.4.2, but cound not find any update anymore. Weird...
(IMHO the problem that happened is that when I reinstalled the stock recovery, I installed the version from the 4.4.4 firmware, but the OTA update expected to have the version from the 4.4.2 firmware. Can this cause the install to fail like this? Not sure, but I have no other explanation.)
So in order to update to 4.4.4 without wiping my device I had to do it by hand:
download the latest factory image; in my case the file is named mantaray-ktu84p-factory-74e52998.tgz extract the archive:
tar xvf mantaray-ktu84p-factory-74e52998.tgz
extract the image zip inside the extracted folder:
$ cd mantaray-ktu84p $ mkdir image $ cd image $ unzip ../image-mantaray-ktu84p.zip`
flash the boot, recovery and system images, but not the userdata one (as it would wipe my data) [source]:
$ adb reboot bootloader $ # Wait until the device reboots to the bootloader... $ sudo fastboot flash boot boot.img sending 'boot' (4784 KB)... OKAY [ 0.739s] writing 'boot'... OKAY [ 0.132s] finished. total time: 0.871s $ sudo fastboot flash recovery recovery.img sending 'recovery' (5334 KB)... OKAY [ 0.783s] writing 'recovery'... OKAY [ 0.152s] finished. total time: 0.935s
$ sudo fastboot erase system ******** Did you mean to fastboot format this partition? erasing 'system'... OKAY [ 0.048s] finished. total time: 0.048s $ sudo fastboot flash system system.img erasing 'system'... OKAY [ 0.028s] sending 'system' (652994 KB)... OKAY [ 95.901s] writing 'system'... OKAY [ 19.227s] finished. total time: 115.156s
start the system from the bootloader.
And voilà! The device booted to Android 4.4.4 and I didn't lose my data. However root access was lost, but that is extremely easy to restore:
download TWRP and SuperSU reboot the device to bootloader: adb reboot bootloader flash the custom recovery: sudo fastboot flash recovery openrecovery-twrp-2.7.1.0-manta.img boot to recovery and enable sideloading (in Advanced --> ADB Sideload) sideload the SuperSU zip: adb sideload UPDATE-SuperSU-v2.02.zip reboot and start the SuperSU app.
I'm sure all of this is common knowledge for a lot of people. But it's not obvious to me, so I'm just putting it here for the next time I need it smiley
EDIT: Just tried it and I can confirm that it works well to upgrade from Android 4.4.4. to Android 5.0 "Lollipop"!
