Default [Q] Thinkware tablet jtag pinouts

Hi, I have a General Mobile (same as Thinkware t10q) tablet and it doesn't boot. It has a Exynos 4412 (S5PC220) Samsung Cpu. Hardware name is "WILLOW". I found on board 20 pin jtag connector but pin connection is different from standart 20 pin arm jtag.

7 of 20 pins are connected to cpu (?) another 7 pins connected to ground. 3 pins connected 2.6V Vcc

Riff box probe result:

1- 0.03 / 1.83 -> pullup to 1.8V with 110k resistor
2- 0.91 / 2.25 -> pullup to 2.6V with 47k
3- 0.92 / 2.26 -> pullup to 2.6V with 47k
4- 0.91 / 2.25 -> pullup to 2.6V with 47k
5- 0.92 / 2.25 -> pullup to 2.6V with 47k
6- 1.39 / 2.31 -> pullup to 2.6V with 10k
7- 0.00 / 0.001 (180mA) -> always logical "0" but not connected to ground. (Box said: "possibly out")

I've tried many combinations. I think TDO is no.7 but could not find the truth. Does anyone have any idea?
