 Please donate to support OMA and CrewRKTablets firmware work, thank you !

Hello oma,Â
I have a tablet branded "turbo x ice IV" from a retailer in Greece. The tab is physically identical to N90 II, but it is an rk3188 with 2gb ram and a retina display. The link of the product is here.Â
I tried changing the firmware, but I did not made a backup first, and now I am stuck.Â
When using your 4.4.4 or 4.2.2 v88 rk3188 (I have a chuwi v88, thank you for your efforts) firmware with the  pd800_freelander  kernel  (seems the tab is a Xoro PAD 9719QR clone or something), everything but the touch screen (and the orientation) works very nice. I have bt, wifi, sound, battery monitor and the tab is fast.Â
the pcb has t-chip tr976qv11 printed on it, which returns zero results from google.
Is there any hope that you could guide me to get the touchscreen working?Â
Â
from a  dmesg on the tab, i can see that it says
input: ft5x0x_ts as /device/patform/rk30_i2c.0/i2c-0/0-0038/input/input
then tries to open the i2s bus, and then fails (no ack) sayingÂ
ft5x0x_ts 0-0038: ft5x0x_probe : fail to read TB lib version and vendor id
and later on it saysÂ
input: sis_touch as devices/virtual/input/input3 (input2 is a mouse I have plugged in)
[MSI TOUCH] SiS Touch Reset HI
and again it fails after trying to read the i2c (no ack) bus giving:
gt2005 read reg(0x0 val:0xc0) failed, try to read again
read chip id high byte failed
[MSI TOUCH] SiS Touch Reset Low

No tab is identical the other! Every tab has is specific kernel. When it is gone (by flashing a strange firmware/kernel into the tab) the game is over.
Pls contact the retailer for providing the genuine firmware.

thanks for replying.Â
I know that I should have at least got a backup of the kernel. 🙂
Anyway, I will try a bit more, everything is working fast using the RK31_kernel_3036_hr_p800_freelander, except the touchscreen. I believe it is a ts chip, and I most probably erased it during the flash prossess. I believe I am at this point, I want to give it a go for the sake of fun.Â
Do you happen to have a ft5x_ts.ko module compiled against a kernel like the p800? 🙂
Then again, it may be the msi sis touch that is actually the connected device to the screen, it reports two devices for ts control. If you have come across a ko for I2C Touch panel driver for SiS 9200 family, I would try that as well.
Otherwise, I wil go get another one and extract the image from a working machine. Thanks for your time, and for the great work you have done with rk firms.Â

Oma, please ignore the modules request if you have seen my message,
I was mislead, I have made it work, I found a working tablet and extracted the kernel from it.Â
It appears that it uses the GSLX680 ts controller, with leads me to wonder, in this post of yours, you used a kernel that tried to load that same controller, do you happen to remember which kernel was it? (ok found it, its bob #11, thanks)
I am uploading the kernel in case anybody wants to play with his device.
This is for Plaisio computers ICE IV tablet.
