[Question]DMG10600C070_03WTC lost touch after update to V22/V65

petr.polezhaev

Hello,


I apparently managed to kill the screen with my experiments.

1. First I've updated to OS V22 and UI V65 for new features. I've updated the INI file as was instructed
2. The screen worked but the display lost any touch control. Everything else was operating normally - the display would react to variable changes, simulated clicks, etc - but no finger touch.
3. I've tried flashing numerous factory demos I had and I found on these forums to no avail
4. Then I thought to try to re-flash V22/V65 to a newer version (from http://inforum.dwin.com.cn:20080 ... 1145&extra=page%3D1) - previous was 2024*, this one is 2025*. That also killed the display.
5. Now I have black screen with backlight. I've tried re-flashing the INI file - the flashing works (the screen switches on, I see the blue screen with updates) - didn't help.
6. Flashed GUI V65 2024* again (from dwin-global.com, https://ecdn6.globalso.com/uploa ... S2_V65_20241029.zip) - the display is back.
7. Still no touch

I think the problem is V22/V65 but I can't find the old V21/V62 (I think) files to go back to. But maybe I just don't have a proper CFG

Can you please provide me with the proper CFG for this display and/or, if possible, the V21/V62 files for a downgrade attempt

The backplate:


The display ribbon cable id:


Thank you.

The following is the factory-generated CFG file.

That didn't help

BUT downgrading to V55 from http://inforum.dwin.com.cn:20080 ... &extra=page%3D1 did

I'll try to do partial updates to see if I can find what version exactly causes the issue

In order of testing:
V20 + V55 = touch works
V22 + V55 = touch works
-- os no longer updated, does not seem to related to the problem --
V65.20250926 + INI.20250721 = no display at all
V65.20241029 + INI.20240607 = display, no touch
V55 = touch works again
V55 + INI.20240607 = touch still works
V55 + INI.20250721 = touch still works (not sure if INIs are actually flashing without GUI)
V65.20241029 (no extra ini file) = no touch
V55 = touch works again
V70 + INI.20250721 (both flashed at the same time) = no display
-- at this point I thought that maybe you actually need to rename the ini files includes removing the date suffix, otherwise they aren't flashed at all --
V55 = touch works again
V65.20250926 + INI.20250721 (renamed) = no display
V55 = working again
V71 + INI.20250721 (renamed) = no display

So basically V65+ = no touch and newer (2025) version = no display. INI files, as far as I can tell, don't do anything at all (I am flashing via the sd card) - they are not listed in files and not counted.

Theory: all factory demos on the forums and the website and incompatible with the V65.2025* and V70/1, which is why it does not show anything, even though the flashing display works. So there is no error there, just the fact that you probably need to make a custom firmware for those versions? And V65.2024 is just broken.

Theory 2: This display is not supported on V65+ (it seems to be EOL?)

Can you please provide a GUI for the version of V6* that  was before V65? V64?

This is the factory engineering document.

Awesome, that worked perfectly. With that demo I am able to update even to V71 and it works, touch and all.

The english demo still doesn't work (no display) but that confirms it's just the demo issue and not anything with the display or firmwares.

Thank you very much for your help!
