Its listed as a test firmware.

Been running for a couple of days now.

For me its a very good one, even with the oc kernel installed.

Battery life is much improved. Was getting at best 8hrs on all v2.04 firmware.

v2.06 is giving me 2 days including some browsing etc.

You dont have to have multiwindow enabled to get the previous apps to work.

Overall its a very nice update and fixes the niggles that were present in v2.04.


Thank you Farscape1, for the detailed reply. Which version do you refer to: originally posted in Cube website or kasty-cube_u30gt2-422-206t_20131017-rooted4?

This is the pre multi window one.

Kasty:[ ROM ] Cube U30GT2 Android 4.2.2 custom root firmware version 2.04 test version (2013/07/06)

Or the original direct from cube


The v2.06 firmware, i knocked one up myself.

But originally tested kasty v2.06 rom to see if it was any good.

Was pleasantly surprised when things worked properly.

I know this has been covered many times before. I have upgraded many devices to custom ROMs in the past, but I felt the documentation here was a little lacking. So, when I eventually figured out all the tools I needed, the steps were pretty straightforward. So I documented them and they follow here.


I started with a stock Cube U30GT2 device, stock F/W 2.03 installed out of the box. I was running this from Windows 7 64Bit.

You will need:

  • Rockchip Batch Tool v1.7
  • Rockchip Drivers v3.5

First step - ensure your device is charged.

  • Connect device - it should be recognised standard USB connection.
  • Start 'Rockchip_Batch_Tool_v1.7\RKBatchtool.exe'
  • Device should show as connected (1).
  • Click Switch (device screen will go black)
  • If it fails installing drivers (it should):
  • On Windows, click Start/Run, enter 'devmgmt.msc'
  • Find the unknown device
  • Right-click, choose 'Update Driver'
  • Choose to find the driver yourself.
  • Navigate to 'Rockchip_Batch_Tool_v1.7\RockusbDriver'
  • Ensure Subfolders is checked and choose to install.
  • Confirm install
  • When complete, check RKBatchTool again - the device should now show as connected. If not, reboot the device (holding power for 5-10 secs, may have to do this twice) then start these instructions again.
  • Extract the ROM zip (currently, should extract to update.img)
  • Load the new rom ('...' next to FW Path, choose update.img)
  • Click Restore
  • Log will display in the window similar to the following:

 **********Restore Action**********

  • When complete (<1m) device will reboot.
  • Device will display as Recovery, with a Lloyd Android with a belly full of icosohedrons (I think...)
  • Device displays:

 Formatting /data
 Formatting /cache
 Formatting /mnt/sdcard

  • (takes around 2m)
  • Device reboots again
  • Now you will see an ArcTablet splash logo, followed by a different animated chinese startup logo.
  • Device will take much longer to boot - around 2-3m rather than 1m. This is normal on first boot after upgrade.
  • When device starts, it will be in new device help mode, showing you how to start apps.

About the ROM:

Apart from a little slow-down when starting the device after the upgrade, everything seems smooth. The Multi-window operates well, although the help is pretty atrocious. Again, if it helps at all, my version of how to use the functionality follows:

Multi-window can be enabled in settings.
A new button appears on right (can be moved by dragging it) which allows you to set the apps into different layouts:

  • 2-win - 2 side-by-side resizeable windows
  • 4-win - Overlaying Floating windows
  • Full-screen - normal

2-win mode.

  • Click on a window enables it.
  • The white bar in the center can be dragged right and left to increase/decrease the size of the windows.

4-win mode.

  • Click on a window enables it.
  • Editing the size/position of the window can be enabled by putting 3 fingers in the window a dragging down sharply. Window will ghost.
  • Single-finger drag to new position
  • Pinch-zoom to change size
  • 3-finger drag up to fix position/size.

All modes:

  • Any application should have a new title-bar button on the top right, to allow changing the app to 1-,2- or 4-win mode.

Here's looking forward to 2.06
