Here is an Android 4.4.2 KitKat rooted firmware for the Cube U30GT2 tablet . This custom firmware is based on Chinese KitKat Funrom_Studio firmware dated 2014/06/06.Â(Funrom_Studio-CUBE_U30GT2_4.4.2_V1_140606.img)ÂÂ
Â
Build information:
Kernel:Â Linux version 3.0.36+ (tangy@tchipserver2) (gcc version 4.6.x-google 20120106 (prerelease) (GCC) ) #95 SMP PREEMPT Sun May 4 15:50:58 CST 2014
Android 4.4.2:Â CUBE/u30gt2/rk3188:4.4.2/KOT49H/eng.root.20140211.100632:eng/opinions-on-teclast-p90hdst-keys
ro.rksdk.version=RK31_ANDROID$(PLATFORM_VERSION)-SDK-v1.00.00RK3188Loader(L)_V2.10.binÂAs you can read, this firmware seems to be mostly a kernel update as the Android system is still one from February 2014.ÂCustom firmware features:
- root with latest SuperSU version 1.99r3Â (free version)
- removed most Chinese and unnecessary applications
- Google Play Store fixes so more application are visible/compatible
- updated busybox v1.21.0.git (2012-11-29)
- Unix like init.d boot scripts support, more details on init.d scripts here
- changed permissions on external sdcard to allow write access
- increased space for applications (/data partition) to 7 GB
- disabled OTA updates (may cause problems, see Notes below)
- added Google Experience Launcher (GEL) in addition to Cube's stock launcher
- kernel modules (cifs, tun, lan, serial, xpad) compiled by Oma &Â Crew RKTablets, thank guys!
- optional ClockworkMod (CWM) Recovery easy install package (apparently reported to be not compatible with this firmware)
- multi-user support thanks to didierm contribution
- update 2014/06/11: replaced stock Asian keyboard by Hacker's Keyboard application
Notes:Â
- any update received thru OTA may interfere with our custom firmware, we recommend to refuse any update pushed OTA.Â
- current KitKat based firmwares should be considered as beta softwareDownload:Â kasty-cube_u30gt2-442-funromstudio_20140606-rooted7c_mu.zip
Flash with Rockchip Batch Tool version 1.7, use Restore button.

Please report any problem with this firmware, I can't verify this custom firmware works as I don't have anymore a Cube U30GT2 tablet to test the custom firmware.

I have bought two tablets U30GT CUBE-2. One of the tablets, I've installed the rom listed in this thread (kasty-cube_u30gt2-442-funromstudio_20140606-rooted7c).
For the tablet that I've installed this rom the result is satisfactory, the tablet is more stable and faster. I've passed the test AnTuTu Benchmark v5.1 with a score of 22.280 (which is pretty good).
However, I've found two errors that do not know how I can fix. I would appreciate any help.
* The brightness of the tablet and its brightness decreased.
As I have two tablets U30GT2, a tablet has rom with 4.4.2 and other tablet with rom original (android 4.2.2), I can easily compare.
I compared photos and videos, and the original tablet has a luminosity and higher brightness, and sharper colors.
I've even gone back to the original rom and brightness and luminosity is improved. I installed the rom again (kasty-cube_u30gt2-442-funromstudio_20140606-rooted7c) and tablet becomes to lose brightness and luminosity.
Do not know what can occur, because the resolution (1200x1920) and density (240dpi) screen did not vary from the tablet that has the original rom.
Can anyone give me any idea what this error can occur?
* Every time I charge the tablet, starts.
This error, however, also happens in the tablet with the original rom.

I resolved this problem with flashing custom kernel from this topic, I used kernel kernel_305kitkat_cpu1800_t14_gpu798h_ddr667.zip, brightness is much better but regulation works upside down, quite funny but I can live with that.
Another problem is rotation, its twisted 90 degrees to the right. I found the solution with these steps:
1. install Terminal IDE
2.Install ssh/sftp server
3. Login via ssh to the tablet
4. type:
/data/user/10/com.spartacusrex.spartacuside/files/system/bin/bash --rcfile /data/user/10/com.spartacusrex.spartacuside/files/.bashrc
mount -o remount,rw /system
vim /system/build.prop
5. edit ro.sf.hwrotation=270 to ro.sf.hwrotation=360
exit, close everything, reboot, done
Probably you can edit build.prop directly from the tablet, remounting /system partition first, but this way was easier for me

Hi,
Â
I try to install firmware in first post but i cant manage to make it work. I tried to install USB drivers for my tablet but they seems not to work even if i try to install in compability mode. Â And when i loaded firmware in rockchip batchtool and press Volume + buttom and connect the tablet to computer nothing happends.
Â
I have Win 8.1 64x system. What to do to make it work?!
Â
I have earlier installed other firmwares through Rockchip batchtool and it has gone well...but this time not.

Thanks Admin
I spent these last days trying to "wake up" my cube u30GT2 tablet, as I was asking questions to everybody.
I thank you all.
Finally I managed to connect the tablet to my pc but Rockchip Batch Tool v1.7 only displays a blue connection.
I can not update or restore anything.
What should I do now ?
Thanks again.

You can try androidtool instead of rockchip tool to flash the rom. I thought the blue icon would too let you flash the rom though. What error do you get?
Thanks Mark06 for your reply
When I press restore ( with different images ) the color starts flashing yellow and then gets red:
I get (layer 8-4) Download boot fail
"Restore done sucess ( 0 ) Fail ( 1 ) Time ( 10234 ) ms
All this in red letters.
I tried several images but it seems that nothing works.

Have you downloaded the map apps? I seem to remember with this rom or the other kit Kat rom that there was an issue and it was fixed downloading the Google map or Google earth app.
Also be sure to set up Google + to show location if you haven't in the settings.

You should flash a rom with the same bootloader. So 4.4 or 4.2 android version. The one bootloader is first generation and works with 4.1 and 4.2 and lollipop, the other bootloader is second generation and only works with 4.4 android.
