Hi vasil_d, sad to know that you bricked your U39GT 'cause it's thanks to you if I use KitKat without problem on my own tab.

Didn't you said that you got a tip to unbreak a bricked one :

Hardbricked the device twice but after opening it and short circuiting 2 terminals to enter MASK mode I did recover successfully.

Hi guys.

I want to inform you that I am stopping the development of roms for the U39GT.

I was on the finishing line of posting a 4.4 KK release V1.0 with hybrid kernel and tweaks but my tablet did brick.

I am experiencing NAND problems with the device. Not able to write to the NAND memory. I did a MASK mode flash but I did not fix the problems.

So i want to share my final thoughts about this device:

PROS:

- BY FAR the best screen that I have used and viewed (brightness, resolution and view angles)

- very good capacitive touch

- good and long lasting battery

- good overall build quality (front, back and assembly)

CONS:

- the RK3188 Kernel and android SUCK. Period

- the weak wifi reception

- the slow overall feel - thanks again Rockchip

One last thing from me - If you want to buy a CUBE tablet buy it, BUT TAKE IT WITH MTK chipset. That is wath I am going to do some day when I decide to spend again aprox 200 USD :-)

sad to read that... thank you so much for your work

sorry for my bad english

I did recover the tablet befoore from hard brick - meaning no bootloader, no MBR nothing (empty NAND chips).

Now I have problems with NAND writes (hardware/chip is) unable to write (change states) of the memory cels.

Any ways. Now the el. engineer in me is waking up again and I have decided to use the screen on my RaspberyPi or mount another mainboard to this screen some day / some how.

If I have any progress I will write.

Anyone ?

Do a hard brick recovery. Meaning:

1. Power off the tablet and open it

2. Unplug and plug the battery connector

3. With a needle short circuit pins 7 and 8 of the nand chip

4. Run the flash software and load the image with the rom (or do it before step. 3)

5. While holding the VOL+ and PWR buttons and plug the USB cable.

6. In the RKbatchtool the square 1 box should be BLUE (i think)

7. Press restore button.

If that flash mode is not successfull the you allso have another problem.

I did it from mask mode too and same thing, black screen with lights, and I try to do short circuit when that recovery is blinking from time to time hoping that It will show eventually like stock rom did when I restore it, but no luck. I was doing pin trick for like 45mins and nothing, and when I restore stock rom I took me like max. 5mins to restore screen with pin trick.

Hallo again guys.

I have a final request to PRIMUS.

So Primus may I ask you to do one small kernel mode for me.

Pleas make me a 1.06 kernel mode with the following setting bellow using rkpatchomatic tool.

Here are the settings:

CPU values - MHz @ Voltage

504@0.950

816@1.000

1008@1.075

1416@1.250

GPU values - Mhz @ Voltage

200@1.000

400@1.100

600@1.200

GPU values - Mhz @ Voltage

600@1.300 (or 1.275v if 1.300v is not available value)

If you do not have the IMG file with the kernel you cann download it from here:

Happy New Year to all

I am also sad because vasil_d can not develop ROM for u39gt Cube.
After many tests, I decided to install Kasty ROM because it is the most compatible with the app. At the same time I flashed the vasil_d's Kernel ROM 4.4.
The result has been wonderful because the tablet works very fast. The problem is it's too unstable.
Vasil_d, you could do a better Kernel?

Hello to all!

I have arrive to this post today, and after reading all the posts, I see that any link for any roms works, all are down.

Anyone could upload some rom of the latest 4.4 vasil_de rom or the modded 4.2.2 rom from previous posts?

Thanks!
