Downgrade firmware version

This is a guide that I would have found really helpful to downgrade the firmware on the Asus Cube. I'd like to see it added to the wiki. I used Ubuntu, but I'm guessing that windows would work just fine too. Cube was connected over ethernet to my ubuntu server

Grab necessary 32 bit libraries if you're running 64 bit ubuntu.

Code: Select all

sudo apt-get install ia32-libs unzip -y
Download and unzip Android SDK

Code: Select all

cd ~
wget http://dl.google.com/android/adt/adt-bundle-linux-x86_64-20140702.zip
unzip adt-bundle-linux-x86_64-20140702.zip
cd adt-bundle-linux-x86_64-20140702/sdk/platform-tools
Connect to your cube (get IP from settings> Network> Status) and reboot it into recovery

Code: Select all

./adb connect <Cube IP>
./adb reboot recovery
Download the firmware to your desktop and put the zip file on a usb stick. Get the MASTER.20130327.094230 version from http://www.gtvhacker.com/index.php/Asus_Cube. Rename it to update.zip. Your cube should be in recovery by now. Plug in your usb stick. Select "Apply an Update from USB". Locate the update.zip file from your usb stick and press enter. This will take a few minutes. Once complete, I also made sure to wipe the cache partition and suggest you do the same.

and it worked? wow. you'd figure the recovery would block downgrades. what version did you downgrade from?

i'm tempted to consider updating and then trying to root the latest cube rom using some newer 'universal' root methods, but i didn't want to end up stuck. if you can downgrade, that gives some hope that I wouldn't. (although no one has the install zip for the factory version, which is the only version that cuberoot works on, right?)

Hi Roman,

1 for the dual core version.

Should be nice to have a updated version of that.


Thank you, reg31
