Didn't work for me. I tried a 2.03 and 2.06 but it didn't work.

You said "take this rom from here: U30GT2_v2.03_4.2.2_20130606U30GT2_4.2.2_v2.03".

From where?

 

I was lucky that it let me put back kitkat.

Hello cxdani,

I'm sorry!

The rom is from this thread at this forum:

http://www.arctablet.com/blog/forum/cube-u30gt2/u30gt2-4-2-2-20130606-v2-03-clean-root-4gb-aosp-look/

 

It's important to use the batchtool 1.6 and do an upgrade not a restore!

 

Works fine for me.

I tried that image. Not working for me

This is what I'm doing:

- with tablet OFF, I connect PC to Tablet USB

- run rookchip batchtool 1.6

- press VOLUME UP + POWER, then release buttons to make the tablet to be detected by the batchtool

- flash the image by pressing Upgrade

 

Failed when verifying firmware.

Works like a dream to go back but you must flash boatloader alone first from "ROMKit4.2.2v12_V2.04_20130810.zip" and in the RKtool you must rename the loader to 1.24 from 1,04 othervise flashprog doesnt find the file, just klick on the field and change the 0 to a 2.

1.rename to 1.24 in tool (not the file)

2.Erase IDB

3.unmark everything exept the loader that you must mark and flash.

4.unmark the loader and mark everything else and flash.

 

This has worked for me 100% when i flashed bacck and forth, because when you upgrade to 4.4.2 you get another bootloader so you MUST flash the one for 4.2.2.

I was in DJ mod kitkat 19/2/2014.

I managed to downgrade to 4.2.2 taking these steps:

  1. Go to Arctools > Reboot to bootloader
  2. In case your Windows have no drivers for bootloader, google "RK3188_ROOT for CX-919 FW0715 MOD by Everal.zip". There i found proper drivers for win 7 64bit.
  3. With Rockchip_Batch_Tool_v1.7 i flashed [VonDroid.com]-U30GT+2+V3.0+20140219+4.4 image.
  4. With Rockchip_Batch_Tool_v1.7 i flashed Official v2.06. Trying to flash official v2.06 from other kitkat versions failed repeatedly.
  5. Root via RK3188_Root_Tool
  6. Install Arctools
  7. Via Arctools install CWM 6.0.3.1
  8. After that u can install any cwm rom you like, or debloat official rom and stay with it. I opted for the latter.

run rkandroidtool and then eraseidb(having the cube connected through usb). Then when you start rkbatchtool (cube off, hold volume button pressed while connecting to usb), it should turn blue instead of green. Then you can install android 4.2.2
