Vanku AA0611B firmware - MTCD Android Head Units Q&A

Hi there,
i got a Vanku AA0611B heat unit a week ago. Rooting worked fine but yesterday i moved the default media player from system apps to normal apps and now i am stuck in black screen. I am searching for the stock ROM to recover. Also it would be nice to know if someone knows how to enter the recovery. The ways i found with holding reset sadly does not work.

Is it an MTCD/E device, post MCU version

How can i do this with black screen and not booting?

It is booting up again. Tomorrow i will look up the exact MCU Version.
The support sent me a link with the original firmware and the mcu image( https://mega.nz/folder/zCRizRAa#Fb966XsXBuTZDoVPS532mA )
The support told me, that the update should start automatically but it didn't. I had to enter recovery.
For others having problems: the manual says "Press Home-Button and hold, press RST and release, release Home. Press Home and release"
My problem was that i thought the Home-Button is the button which brings back the home screen and has a house-icon on it, but the manual is talking about the volume knob.
The SD-Slots are not marked. The SD-Card must be insert in the left slot.
From there you can install dmcu.img and update.zip within a few minutes

MCU Version is MTCE_HT_v3.71_1
So maybe a mod can move this topic to MTCE

Doogee DG550 FIrmware upgrade to 4.4.2

I flashed Doogee's Android 4.4.2. firmware release, and It's much better than 4.2.
I do have what seems to be an odd issue. On first boot I did the initial setup -- the series of four or five screens before the home screen. There is even a brief tutorial which you can view or cancel.
About a week later I did a factory reset from the off state using the volume up + power button, and when the phone booted I went directly to the home screen -- no setup.
Any comments as to why?
Thanks.

Guys guys Science may have found a solution right now ... will luckily I do not know, however, acts, then taken by anxiety, I did a downgrade of the OS taking it to the first version available from asus website:
https://www.asus.com/it/Phone/ZenFon...Desk_Download/ and download the oldest! that is, the first at the bottom, downloaded the zip file, and insert it in SD, reboot the phone in boot pressed power button and volume +, with selected RECOVERYMOD down key and select it with the power button, go into recovery and select update from SD car, flashed the firmware previously downloaded and placed in SD at the end you do the second wipe data factory and wipe cache, and reboot, there will dawn upgrade the touch, but the startup screen with the set of languages, now do not do anything and restart again, now it appears the annoying firmware upgrade again always with 0% but the screen "press and hold the power button ... etc .." do it and you will see that it will restart the cell, proceed quietly with the set of the options and creating acount, now every time you turn it on or ravviate, will win for a second the annoying pop-ups but the cell will reboot again and will turn on normally, it is not the best solutions but at least you can use your device, I hope I was helpful and let me know
PS SORRY FOR MY BAD ENGLISH

Can't Use Buttons In Recovery Menu After MCU Updates (MTCD PX-5 Android 6.0)

I was able to use my car's radio power on/off button in my MTCD device's recovery menu without any problem when i first bought my device. From that time i installed every MCU update (my device is from Witson, i used Witson's MCUS) to my device.
Now i found that i can't use the same button in recovery menu. Problem is i don't know which MCU version i should revert. Everytime i install wrong version MCU and enter recovery menu => i must disconnect car battery to reboot my device.
Is there easier way?

Blank screen and confused

I have a px5 radio packed as kanor. It is a px5(1024x600) running 8.0 with mtce_kld_v3.01_1 and has physical buttons.
It was running ok. I went into factory settings and changed the led color and changed the mapping on one button. It said it needed to reboot. It did and now I just have a blank screen.
I can get into recovery mode. I have tried to flash a new mcu from the 4pda site (also 3.01) as well as an update.zip. one I had went through but when it comes up I still have the black screen. I have tried an update.zip that was rooted but that just fails. I tried creating a boot sd card and upgrading (I think this was in malaysk thread. I have read so many things on this sure and am just starting to confuse myself even more.
Can anyone please help me understand what I need to do to try and get this thing back up. I would really appreciate it.
Thanks.
I guess I can not post pictures yet but when I updates the box with update.zip this is what it said on the screen

That looks good to me but I still reboot and get no screen. What am I missing?
Hi.
I have a similar problem.
I was updating my radio auto, the original was on android 8.0 and updated to 10.0
so far so good ... then I wanted to update the mcu because it was at v2.80 and put the file on the sd card and clicked on mcu update. the radio restarted and a screen appeared like this:
- a screen with chinese Letters
- a red, a green and a blue bar
- a Version PX5 V1.1
to get out I had to take the card out and press the reset button. now the screen goes black and nothing happens. but if you put the card in and press reset you will return to the screen with Chinese letters ...
the worst thing is that I cannot now enter recovery mode.
I tried using the reset button and nothing .... the only signal that seems to be for recovery mode is to press the power button for 10s, the lights flash, then I let go and charge again but nothing happens ...
Help me, please...
After the lights flash when holding the power button let go then press again right away.
I never get any letters out anything on the screen unless I enter recovery.

If you get recovery button sequence LED flashes, or into recovery, MCU is fine.
No screen, try OTG Android recovery - refer my signature.

Thanks for the suggestion. I just started to read the thread. DO I really still need a jig? Afraid that might be beyond my skill set.
Either way, Thanks.

MTCD PX5 Device Suddenly Can't Boot

I have MTCD PX5 Android 6.0 device. I was updated recovery to Android 10 and installed Witson's Android 10 rom and was using it without any problem for 2-3 week. Today, suddenly my device stopped booting.
When I start my car head unit shows Android 10 logo for some time and than it goes to black screen. (Without backlight). It looks like it turns off.
I want to enter recovery mod and reinstall the rom. How can I enter recovery mod in this situation? My doesn't have a physical power button and I was able to enter recovery mod from rom by using an app called "Quick Reboot". When you select the recovery mod it simply reboot to recovery mod. Than I was able to select recovery options with external keyboard. The bad thing is as i said device can't boot in to rom.
I turned off the device by removing the battery and than connected keyboard and turned device on. While it was trying to boot I keep pressed ALT(Right side) + PrintScreen and keep pressing & releasing 'E' button but nothing happened.
How can I enter recovery mod without dissamble the unit?
