Inverted Axis X in Pipo M9 (no pro). HELP! - Android Q&A, Help & Troubleshooting

Hello everyone. I have a problem, I changed the touch screen of my m9 pipo (normal, of double nand) and I installed the rom Rileyrom, and my problem is this:
Rileyrom install normal, touch all good except in the X axis (with the tablet horizontally, the right is left and vice versa), the up and down works fine
If I install the modified kernel, the tablet not start, has bootloop.
With an official rom, the touch screen does not work (imagine that will be subject of the drivers...).
Kasty-rom with pipo-m9 happens to me as with the Riley, right is left and vice versa, the up and down works fine.
Someone I can invest the X axis of the kernel function properly for me?
As I can fix this problem?
I managed to decompile, and recompile the kernel, with the ImgRePackerRK program, but can not I edit the file .unkrnl to reverse the axis X.
Can anybody help me?
Sorry for my English translator ...
Thanks for advance!!

Wopad i7(cloned tab) mirror screen after update

I have been using this Wopad i7 cloned (rk2918 based) tablet for around a month and suddenly it stopped working. So i downloaded the firmware from topnotchtablets but the touch screen seems to be mirrored and working the opposite sides.
when i select the option in the right, the left one gets selected. when i select the option in the left, the right one gets selected. Its become really annoying for me.
I have installed many rk2918 based firmware for my tab but all the firmwares are having the exact mirror problem.
can anyone suggest be how can i fix this problem?
any help please?
I have the same problem with the Arnova Childpad. There is no setting to calibrate the screen, and also in the Android filesystem I cannot find any files to erase so the tablet is forced to re-calibrate at next system start. Any help would be highly appreciated.

needed a firmware (stock or custom) to be able to use some apps etc, so i flashed the one given here:
RK2918 Tab Odys-Loox rocks with CyanogenMod 10 / 10.1!
(http://forum.xda-developers.com/showthread.php?t=2012654, beta build - v1.2)
after flashing completed, tablet hard bricked. no screen, nothing (even backlight of screen not working, so it is not a "black screen of death" but instead "death" only i guess :laugh: , though it reacts on charging with led)
anyone have any idea about what happened or how to recover it?
ps. atm i work on "29-30 pin shorted" thing (http://www.slatedroid.com/topic/41388-unbrick-instructions/) but not sure if it will work for me yet.
update
I was able to de-brick it (couldnt use "short 29-30 pins" thing, chips had a metal cover over them soldered to mainboard, I used reset button with volume buttons, I pushed them like crazy alot of times and somehow got rockchip usb flash state for once then re-flashed stock rom (I had rom-dump files and original "update.img"), it is working now with stock rom.
continued as follows:
1) Tried alot of other roms from similar tablets, some just stays at android screen, some works with corrupt graphics, etc
2) Oma_Odys_Loox_JB_CM10_4.1.2_v1.2 = killed the tab, debricked by luck
3) Oma_Odys_Loox_JB_4.1.1_v1.2.1a (with Oma_extSD_to_NAND_OTG_fix) = works till welcome screen, but touchpad not working so i couldnt check the system further more
4) Oma - Odys Loox GB 2.3.1 v1.3a = touchpad not working, and graphics weird (low color depth+some minor glitches on image), just waiting at main screen cause of touchpad, adb shell works (with root)
5) flashed original kernel over Oma - Odys Loox GB 2.3.1 v1.3a, screen resolution, color depth fine now, touchpad working too, but have problem with sensor, left-right or up-down shifted up to tablet position, trying to fix it
6) activated "ro.sf.hwrotation=270" in build.prop, sensor fine now. Only problem left is touch screen Y axis inverted
7) still working on Y axis issue, but weird thing is calibration works correctly, no inverted axis! and succesfull. but then I have to click upside for something downside or downside for something upside.
8) darn. it is not up or down. it becomes left or right if flip tablet to 1 side.
9) i decided that problem is about touch-driver and i dont have enough knowledge to fix it. left over tablet with factory rom, working but ehhh.
note:
thx to Oma7144, i learned few things from his/her posts, i try to find thx button now xD

[Q] Fix touch screen with CWM ROM

Hi,
I have a Qware TB-9718D tablet (rebrand of ployer-momo11-speed) with RK3066 CPU and Android 4.04.
I've installed the CWM-ROM-Ployer_Momo11_3-0-8_M1_software_chinese-version_4-2-2_20130425-4-2& CWM ROM (Android 4.2.2) on the tablet and it boots just fine.
However, the touch screen does not seem to work anymore with this ROM.
I have tried two touch screen fixes (which were suggested on another site): one of which was the 907c_compatibility_1.2.0.zip
Both files did not solve the problem.
Does someone else have any suggestions on how to fix the touch screen with this ROM?
Could I for example extract the touch screen driver from the original ROM's lib folder and use it in this new ROM?
Thanks in advance.
Does anyone have any suggestions?

wrong touchsreen / gyro driver

Hello,
i had some problems with my android on my dual boot jumper EZPad mini2 so i reflashed it. But because there was no original ROM available i had to took some of tablets with similar Hardware. Now Android is back alive but the touchscreen is not working correct and the gyro sensor too.
So when i touch on the screen it the command is active on an other corner of the sreen.
Similar to the gyro sensor. When i turn it in horizontal direction the grafic is upside down.
The firmeware on its own seems to work fine. With a mouse i can control everythink and even the play store is working.
So can somebody help me to fix my touchscreen and gyro problems?
Regards
Prakti
Without the source code you are out luck. Word of advise. Never flash generic devices. There is almost never any os releases for them as they use a hacked together version of Android and a pirated version of Windows.
there are many chines dual boot devices where you can get roms to flash... but not for jumper as i know. is there no way to just try different touchsreen / gyro drivers?
Or has someone the Firmware for the Jumper EZpad mini2?
