I have a MTCD KGL.
it was on KGL v1.92a
with PX3 wich I upgraded to PX5
running on Malaysk ROM
today I tried to upgrade the mcu to KGL v2.54
the upgrade run fine, but now there is an error message coming up:
Version Unmatch -01
8F267F2C4135B62E0300 KGL 000000000

I already tried to go back to MCU version v1.92a (I still got that file) but flashing is aborted with error message "MCU mismatch"
Anybody went thru this problem already, or is there a posability to force-flash the dmcu.img?
do you have any .cfg files in the root of the path you are installing the dmcu?
if yes remove it
Problem SOLVED.

It did not help. but thanks for the idea.
I started to flash lots of different dmcu, (always without config files)
With KD 2.40 the error was gone
now I am running on KD 2.40 and everything seems to work so far.
I have the same problem with my erisin with an original LM mcu. I tried installing different types of mcu, I tried to reinstall the original mcu, the oldest mcu, custom rom and the original rom, but the problem remains and I do not know what to do. Anyone can help me?
Upgrading, I installed kgl and the problem is gone, but the keys do not match if I try to put the original mcu always the same mistake, and as if detecting the "kgl" as original and not the "lm". I need to reset the mcu ....
Has anyone found a solution for this problem? My HU stopped working with the non original HA MCU, so I had to unplug it and after a rebooting it and reinstalling the original GS MCU now I have the unmatch error :/
Got Erisin 3015 with PX5 6.0 witson board.
Running KGL MCU 2.70 but no autosleep.
Tried to flash different other mcus without success. Alwasy "version unmatch" error.
Any hint to completely reload mcu? There are no cfg-files elsewhere on sd card or stick. But error always comes up.

Hello Everyone! I need help with my Royqueen 9-Inch Android Tab's Touchscreen..
This Tab was brought to me for repair because it was stuck on boot Android Logo so I went to Recovery and Factory Reset the device.. And it booted succesfully. All features are working except that I cannot install my downloaded apps even if I have checked the option to allow installation for unknown source. SO I decided to rooted the device with CWM a13-10part-v2, backed up the ROM in ClockworkMode..And Flashed A13 CM10.1 v1 it was again stucked in bootlogo..Resetting again to factory settings didn't solve the issue. I tried to restore the 2 back ups i have made prior to flashing and both failed to restore showing error while restoring system.. So I tried flashing it with some roms for a13 android, they all boots up but touchscreen isn't working.. I have tried all the ts module I can find but nothing solved my problem.. When I checked the serials on the touchscreen felx inside my device it shows goodix gt 827. I tried updated it with modules that has goodix driver and gt8xx but still not solved..I tried looking for gt 827 driver and I found in code google website but it is on h file type. And i don't know how to add it on my android system files correctly. I am not familiar with this file type.
Anyone knows where I can get gt 827 touchscreen module in zip file so I can update it on my device using cwm or debugging script?
I have found a stockrom of this device mx913_firmware_20121005 but it is a corrupted file and that's the only one I could find.

Hi everyone,
I was wondering if anyone has any experience or any ideas to resolve this issue I am having with my new Gome U7.
While using the phone, I constantly get popups saying I should add Iris for security. And when I actually scan my Iris and have it saved in the system, I get a different popup saying Iris is already inputted (no picture of this, sorry).
I am trying to find a way to disable this. I searched through the system.img and couldn't find any apks or anything remotely named "iris".
I am attaching a screenshot of the log of what happens in the system during these popups.

Thanks in advance!
Update: I flashed phone back to stock Chinese ROM (GomeOS 2.0) and I get the popups even there. I also tried flashing into the ROM that comes with the phone and the problem still persists.
Is there a possibility that I am not flashing/erasing all of the data on the phone and there is something that still persists? I am using SPtools and when I input the scatter file, I make sure all the files are checked. I then flash TWRP boot.img and recovery.img successfully (and root the phone), but again, same popup comes up in android.
Can you disable the iris scan option after you input it? From this vid it looks like you can.

How can you flash rom to your GOME U7 ? can you give me links for CUSTOM ROMS of it I want to upgrade it to latest version thankyou.
Hello, I tried to install a custom MCU with sound patch and now the unit hardly boots. I got it to boot but it shutted off and I wasn’t able to flash the original MCU. I’ve been trying to get into recovery by holding down the power button until the key backlight flashes three times still holding it for three seconds and then letting go and pressing again.I tried with ADB but still no success.I tried making a SD card with SDBoot.bin but I am not able, the program crashes.The unit boots sometime and I am even able to start settings and etc...Thanks.
EDIT: I am sorry the unit is a MTCE_LM.

Next step seems to me to be formatting your SOM flash and reflashing android via OTG. There's alot of posts detailing how to do this, the bootloop thread you posted in is a starter.

Maybe I have to do it or maybe I don't, because a few times it booted into Android. I am thinking about reflashing the original MCU which I have and just wiping all data may fix the issue, if I just enter recovery, that's the problem.
EDIT:I disassembled the unit and got the SOM out, gonna try, but if I fail how do I get it to MaskROM
on PX30?

I reflashed the SOM flash via OTG.The unit still doesn't want to boot.When I hold the power button the key backlight flashes so this indicates the MCU is okay?
EDIT: It showed me multi media on vehicle system bla bla and then BMW logo, which is strange because I reflashed and it should be a erisin logo and it turned off again.
So, after a couple of months running Android 10 without any issue, my MTC-D PX5 screen froze yesterday, and after a power off/on the screen never came back to life, but the panel lights did, showing a low-level boot-loop.
I tried to abort the booting process... no luck. Then I inserted the SD I used to upgrade to Android 10. Screen came back to life, Android 10 logo first, then showing the circle with the "preparing to upgrade" and then this:

Any idea how to recover from here?
This is related to the SOM firmware, right? not the MCU...
@marchnz Do you think that your USB on-the-go HW mod to connect a PC directly to the SOM would help solving this?
Any help is welcome !!!!

If SD card method doesn't work, double check the files used and SDcard.
If SD card just won't work, use OTG / PC-SOM
I hope I am posting in the right place as I have been reading through so many threads in here my head is spinning.
I have a Vauxhall/Opel Astra J with an aftermarket Android stereo unit. there are NO buttons NO RESET button just a touch screen and an SD card slot
This was the only picture I could get while it was running

it was a PX3 1024*680 on MTCE 2.83
I believe it has a rockchip processor?
I downloaded H9k firmware and it asked to erase and install after being inserted to the SD card slot. it restarted and hung up on the Hal9k car navigation multimedia screen. and Now it just keeps rebooting to the same bit and boot looping constantly. I have no buttons I can press on my head unit there is not reset button ether so I'm at a dead end how I can try to boot into a recovery mode and try to install a stable firmware again otherwise I have a paperweight sat in my car.
I'm not sure what other information I need to provide is anyone can help me at all it would be greatly appreciated.

If that doesn't work, you'll have to replace the processor board, maybe you can get it at the bazaar, or you can buy it at aliexpress.
