Hi all, I need your help.

I'm new to tablets, until now I only flashed several Motorola Defies...
Two weeks ago I bought a used tablet on ebay, it was offered as "Cube U30GT2", 32GB Version.
But Total Commander could see 16GB only.. 🙁
Some apps won't install, they missed root rights.
So I decided to upgrade to a rooted ROM, at least I landed at arctablet ;), where I found Kitkat and Lollypop.

First i tried to enter the stock recovery but none of the descriptions from the internet worked for me.
I had to press Vol+ & Vol- simultaneously and hold them while addingPower button for about 4-5 seconds.

I took these versions:
CrewRKTablets_Odys_Iron_CM12.1_LP_5.1.1_v1.1
RK31_kernel_3036_hr_u30gt2_cube
CrewRKTablets_RK31_LP_5.0_v1.0_parameter_dynamic

1st I cleared IDB afterwards I started the run.
The flashing procedure terminated successful but for the recovery i can wait to eternity.
All i could see was a black screen, sometimes illuminated by the backlit 🙁 Grrrrr....

And now??

Whlie I'm writing here I guess my tablet is another model and no U30Gt2.
All inet sources tell me u30GT2 is a plastic model while my tablet sits in an aluminium housing made from one piece (25.8cm x 16.2cm).
IIRC the info tab told:
Android 4.2.2
Kernel 3.0.36+ root@zhangboyu-desktop #619

For the tablet is dead at this moment and I dissambled it today.

I hope some one can identify my model and point me to a working kernel.

Could be everything. Do you have a dump of the stock firmware?

No, of course not 🙁
I didn'd found such option in RKtool...

That's the reason why I asked here.

The only facts I know so far:

RK3188, 2GB Ram, 16 GB Flash
1920x1200 display (IPP1021 61.YJY01.003)Searching for Kernel "3.0.36+ root@zhangboyu-desktop" points me to Android mini PCs, Minix Neo

At this very moment the screen is black, no recovery available.
Only RKtool is able to connect.

Given analog case with one of my Defies I would flash the first stock ROM.

But I have no stock ROM and no idea where to find.

Better to have a Plan B before flashing something strange into a tab.

For the U30GT2 there are several different hardware revisions in the field. And uncountable clones. Every tab has its own kernel (hardware abstraction layer).You have seen that the used kernel doesn't work for your hardware.

However, according to the kernel string it is not an U30GT2. Kernel string points to Yuandao M10. Two different hardware revisions (AZ and ZZ).

So you may try:

AZ - http://chinagadgetsreviews.blogspot.de/2014/10/download-latest-android-kitkat-442_49.html

ZZ - http://chinagadgetsreviews.blogspot.de/2014/09/download-android-jelly-bean-422-stock_21.html

Good luck!

You're right but I don't have any skill in the tablet market and I believed the seller's stories 😉

THX for your answer, I'll try this evening.

Nevertheless my forgotten front view..

You're my hero, thank you so much, muchas gracias 🙂 🙂 🙂

That pics lock absolutely similar to mine and so i started looking for M10 AZ stuff..

in crewrktablet's download section I found two M10 stock kernel, I loaded both and..
in "RK31_kernel_3036_hr_m10_vido_2" I found the string "3.0.36+ root@zhangboyu-desktop #619".. voila!

In a first try I flshed the kernel only, a "Vido M10" flashed up for a second or so ..jipee.
In a second try I flashed the complete stuff again...and the tab wnet into the recovery!

Again, thank you very much for your brillant help!!

Now Lollypop is running...

Some remarks to the ROM..
I'm wondering about all that google stuff.
IIRC CM comes without googlies.
And no file manager but lotta phone stuff...
USB doesn't function properly, debug mode only
