Upgrading Transformer TF701 to 4.4

Download WW_epaduser_V11_4_1_17_updatelauncher.zip (mine is using WW version) from Asus support site, extract UL-K00C-WW-11.4.1.17-user.zip and copy this to the /sdcard folder (of Transformer device)

It is required that the device is running the default stock recovery image, to be able to install the upgrade.

The device will auto-detect the upgrade file UL-K00C-WW-11.4.1.17-user.zip, and prompt the user to install it.

Eventually, the device will boot into the Android 4.4 system.

I am running Debian Linux on my Android system using a minor hack. See Debian Android with no Root

Basically, I need to replace and rename the system sdcard daemon. (after a system upgrade)

I use the PhilZ Touch recovery image (recovery.img), which can be downloaded from this tf701t CWM 6.0.4.7 Advanced Edition / PhilZ Touch 6.25.9 forum thread.

Below is executed in the machine which is connected to the Transformer device via USB cable.

1     sudo adb reboot bootloader
2     # device in bootloader
3     sudo fashboot devices
4 
5     sudo fastboot boot recovery.img
6     # device showing PhilZ Touch
7 
8     sudo adb shell
9     

And, in the adb shell:

 1     mount /dev/block/platform/sdhci-tegra.3/by-name/APP /system
 2     mount /dev/block/platform/sdhci-tegra.3/by-name/UDA /data
 3 
 4     mv /system/bin/sdcard /system/bin/sdcard_o
 5     ln -s /data/local/home/sdcard_deb /system/bin/sdcard
 6 
 7     umount /system
 8     umount /data
 9 
10     exit
11     

Select to reboot from the PhilZ Touch, and after reboot, I can access Debian again.

The new upgrade has an ugly wallpaper!
