Unbranded 10'' Android 4.4.2 - Changed screen resolution

Hi,
I made the mistake of changing the screen resolution from 800x600 to 1280x600 in this new chinese Android 4.4.2 head unit. Now only get a grey screen.
The unit has no physical buttons, only capacitive. It says that is a RK3188 and has 1280 screen resolution.
"Android Car Player GPS Radio Information:

For MCU I could find this:

when double click shows: VW(5.3.18, CONFIG, RDS, BC6, Color, NODVD, Rohm37XXX, TEF668X)
System version: 4.5.7_20160108
Any help how to force it into factory reset mode or somehow change the screen resolution back to 800x600?
Has 2 USB ports (but no sdcards).
Any help please? Thank you.

Hi,
would the post regarding capacitive/on screen button help?
It is said to solder two wires to help/simulate the reset button?
Thanks.
Update: I did open the unit but the board is different and could not figure out how to provoke this "reset" switch workaround.

Did you ever figure out how to fix this problem. I have the same head unit and did the same thing.

GS MTCD Android 6.0 HeadUnit Soft-Buttons Issue and mirrored Touch Input

Hi folks,
I have bought a Xtrons PB96MTVAPL last week. which is a GS MTCD PX5 Octa-Core HeadUnit.
I am very pleased withe the performance of the system and the UI in general.
Since i am pretty new to the matter i played around with it a bit today.
I wanted to optimize the Factory Settings today and "accidently" pushed the "Reset Soft-Buttons"-Option... resulting in directly disabled Soft-Buttons... which is not preferable on a "Soft-Button-Only HeadUnit".
I also have a horizontal mirrored touch input now wich is really crappy and twists my poor brain...
I have contacted the Xtrons-Support but I have the feeling they force me to return the Unit which i dont want....
Is there maybe a way to remap my MCU Softbuttons?
Is there anybody who could send me a copy of his dmcu.cfg for the PB96MTVAPL?
[solved]
Hi,
i solved the issue myself by using the "Reset Toch Screen" function. One has to point at the upper left and lower right of the touch area. After that one can remap the softbuttons.
it was quite a struggle getting there with a totally flipped screen.
Hi. I am also interested in you unit. How is the radio reception, the audio quality and generally the unit? I would like to send me a quick video if you can or upload one in youtube. Thanks

XTRONS D717AL Screen Problem

Hello XDA members,
I have been following XDA for almost a decade and now came my time to ask for a help.
I bought few months ago XTRONS D717AL. First of all, great player, awesome radio tuner. Catches many stations I couldn't with my old Audiovox and Clarion. It comes With Adroid 5.1.1 and Intel chip. Model number says: Full AOSP on Sofia. MCU Ver: HY_SFY170224EF.
But since day one I noticed a weird display actions. Radio starts right after I start the car engine, display pops-up and on random basis, sometimes the display lights up, sometimes not. It takes about 20sec to load the OS and apparently, the touch screen is working. I know where the Quick settings are, if I pull the top navigation panel down when the screen is in a working state. There is a Light button, which enlights or darkens the screen.
In a dark state (blank), if a pull the navigation panel down when the screen is dark and press the Screen button, screen enlights. I know approximately where this Light button is and pressing it screen enlights. That makes me think, that the screen darkness goes to value 0 at some point before even the OS load.
I have rear camera and DVR attached, but since I took everything away today except the ISO wiring harness, it makes me think that these AV in signals are not the issue. I even took away the reverse camera control cable, illumination cable, and GPS antenna. Brake In cable is fine attached.
Last week I tried to factory reset the unit – no luck.
Flashed with a firmware from the Xtrons tech support – no luck.
I recorded a video today which I uploaded on youtube (I can't post links yet, too young to do that )
Search "XTRONS D717AL Screen Problem".
If anybody ran into such a problem and a solution, will be much appreciated to share here.
Many thanks.
Edit: I just noticed, that upon switching off the radio, the dark display flashes for a half second on its way going in. Possible display cable issue?

I have never tried to go to recovery of this unit. But, I found another topic here:

Regarding my problem, I returned the unit and it was replaced with a new one since it is still in warranty period.

Dasaita PX6 7" - touchscreen partially working

Hello,
i have Dasaita PX6 7" without hardware buttons and some time ago the touchscreen started to do strange things like i'm driving and i hear the media makes *bop* sound as if i've touched the power touch-button and the screen goes off or it launches a program as if i've touched the screen over where it's icon is.
Now it seems it stopped doing all this but a portion of the screen is just not working, not responding to touch.
The pic of the unit is from the web but mine is the same. I did the color rectangular areas tho to show and say - the green area is responding to touch, the red area is not responding
I write for over a week to Dasaita on Aliexpress where i bought the unit for solution or for new screen - they just read, no answer. I also write to their FB page - no answer.
Because the portion of screen which is not active i can't drag and drop icons from other screens to main screen - i have mouse, but i cant select and drag. Any suggestions?
And please tell me if i can fix this touchscreen (maybe it delaminated somewhere and its not making contact) or where i can get new (because of high chance to ruin this when trying to fix it).
Thank you
Have you ever recalibrated the touch screen?
I don´t know how it works on yours, but for a couple of units it works like all 5 fingers touch at the same time and hold it until you get a marker on the upper left screen.
Touch it as exact as possible and do that for all corners as you get the touch point visible.
For the buttons on the left side you should have a setup in the settings menu.
Hi, i watched videos about the 5 fingers touch but it doesnt activate on mine.
I entered the factory menu /with the 126 password/ where are similar functions and tried them several times just to be sure - no change.
The buttons on the left side are part of the touchscreen even tho they are on the black stripe, its jsut painted, it dosn't matter.
BR
In this case you should get in contact with Dasaita and/or the seller.
May be there is an issue with the controller or firmware.
