Well done sir, thank you for the update. One question, does this firmware include the double-resolution feature where you can switch between 1920x1080 and 1280x800?

I have added a second download with CWM Recovery included in the firmware, see post #1
deinemudda24, it should have it as it is supposed to be included in the system our custom firmware is based on. I can't test or confirm as I don't have a Cube U30GT2 myself.
Cheers.

What are the benefits of a cwm recovery instead of the stock recovery.

Hi All,
Thanks for the second test version of the SDK 2.0 test ROM for the U30GT2. The list of improvements is quite significant, do we feel that this is also achieved or should I apply a reasonable amount of 'sales-factor' towards my expectations?
The list seems to be identical to the previous test version, is there any insight what improvements have been implemented versus the previous test version? In other word how does this test release improve over the previous version?
Looking forward to your findings and feedback on this version via the forum.
Backing Up Settings Multiple Users
Has anybody found a solution to backup the settings on the non-primary (root) user? Apparently all the ‘other’ users are not able to access root or the Android backup features. Only the primary user has this ability. As such I’m not able to back up the settings of the second user. Titanium Backup supports 4.2 but not the multi user function as far as I can track.
Any suggestions on the topic?
Thanks in advance,
Regards,
Iemand

I have installed it few hours ago and therefore not so much can say about this new ROM. Anyway till now everything works nicely. Hope it would not change during the next days of using it. We will see.
Regarding your question I can confirm that this ROM enables every user to change tablet screen resolution from 1920x1080 to 1280x800 and it means good news for all game players. I am not so much interested in gaming therefore I am just wondering what for could I use the decreased screen resolution mode.
If you wish to change resolution than go to Settings/Display/Display mode. Here you can change from HD to Normal mode. Then you will be advised that " System will reboot to change display mode". Finito.

I installed the previous version (the 06/21 version), and it was the smoothest ROM that I had used on this tablet. Earlier today, I installed the CWM version above and had tons of issues. USB mass storage didn't want to connect. It claimed my microusb card was damaged and wanted to format it. ezPDF viewer and Aldiko wouldn't import files.
I reflashed, but it didn't improve, so I'm going to flash the non-CWM version.
Anyone else have the same issues? Anyway, thanks for the frequent updates! If I figure out my problem, I'll update the thread so that nobody else has to make whatever silly mistake I'm making.

I flashed the non-CWM version of this ROM and it works perfectly.

Installed it yesterday, here are my thoughts:
*Runs very smooth, much better than V2.03
*WIFI signal is just fine, fyi I'm sitting next to my WLAN-box and share it with my PC too.
*HD Games like Modern Combat and GTA VC run without lags with max effects at Full HD resolution.
*Switching between 1280x800 and 1920x1080 works fine, it only requires a reboot to apply the changes.
*USB-Keyboard was recognized without any problems.
*Can't say anything about battery life as my tablet is plugged-in most of the time and used like a laptop with the USB-keyboard.
EDIT: Forgot to add that CWM works fine without any problems.
