PX30 Android 10 Bootloop - MTCD Android Head Units Q&A

I have a AmaseAudio Android 10 PX30 Head Unit and I was looking around for root options.
I managed to enable root over ADB with it being detected as rooted and working perfectly but then when I rebooted the head unit, it would not turn back on. It shows the first boot logo but then black screens. I can access recovery fine but tried wiping the data but it doesn't seem to boot still.
I have contacted the manufacturer for the firmware as I don't see it anywhere online since it's PX30 and Android 10, although I do see Android 9 PX30 that I might try.
While I wait for their reply, I tried installing MalayMod and Hal9k for PX30 but the install fails in recovery with Error 1001 Status 7. I have researched and it seems to be because it's the stock recovery and broken root.
Any other ideas or ability to install TWRP or something on PX30?

Is it MTCx, post MCU version including prefix.

Downgrading to android 9 - is it possible?

I've got the android 10 beta update, but i need to downgrade back to 9, because an app, which i use for work isn't working under the new system. I've downloaded, the oficial android 9 build from oneplus's site, and was about to use the local upgrade function, but it shows this message.
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
. I'd like to avoid to install custom recovery and custom rom, if possible.
Thanks!
So it shows this

the fastest way back with data loss is to msm the phone back to 9.
Go in the oneplus community beta thread and you will find the correct rom to downgrade.
you can but i twill wiped all of ur data. go to the oxygenos android q beta's thread on oneplus community. there's an instruction there.
It is basically a downgrade package which is installed using local upgrade.
Doesnt Format everything on TWRP and then the PIE works?
Whats the difficulty?

Unable to update 4a 5g to Android 12

Hi All,
Hope this is the right forum...
I have a Pixel 4a (5G). I've tried flashing Android 12 about 10 different ways, but no matter what I do settings shows Android 11. I've tried using the dev flash tools website ( https://flash.android.com/preview/dp1.1) , I've tried the manual download / install from https://developer.android.com/about/versions/12/download .... No matter what, I'm still on Android 11. Am I missing something obvious?
Thanks

All you have to do is to download the device factory image for bramble from HERE and flash it using flash-all.bat, having your device in fastbtoot mode.
If you want to retain your user data, remove the "-w" from the bat script on the line you see the "update instruction".
I did that, just using flash-all. All data was lost, but still says Android 11 (S). I'll try it again with the -w....
S is developer preview of Android 12 but it's still marked as 11 on some places. So if it was that what made you doubt, forget it, it's normal.
OH. LOL.. Thanks. Well, that explains it!

Question Help with firmware update for Joying

I'm trying to determine what firmware link I need to update my head unit.
It's a Joying JY-MQ003N4G, which is not listed in their blog post. Looking at the available options, there's two different links to the same "9 or 10 Inch 1280*720 model with MIPI screen" model.
https://imgur.com/fQShwzS
When joying was contacted for support what did joying suggest?
They suggested this file.
Android 10.0 1280X720 MIPI Screen 2022.1.17.zip
drive.google.com
Which I used to update and then got this.

I've since reset the head unit and tried reflashing with the same drive with the same result. Going to try re-downloading and re-creating the flash drive and try again.

Also do a check of your USB-stick. It is not the first time that an incorrectly disconnected USB-stick, and then reused, has resulted in partly corrupted files in the unpacked firmware.
Used a newer USB stick and repeated the steps. All is well.
Very picky about USB sticks!

Is this an MTCD type device? Post screenshot of MCU versions.
Assuming it is MTCD, what options have been tried from the plethora of posts regarding recovery.

Oneplus 6 phone not starting

Hey guys, hoping someone with more knowledge then me can help me out here. I tried to install a custom from and may have bricked my phone as at the moment when it starts it just goes to a menu screen which has some options on it like wipe data and cache, advanced and exit. I can reboot to fastboot but cant go into recovery anymore. So this is what I did:
I did the adb OEM unlock
installed TWRP
then downgraded to oxygen 10.3.11 with the stock rom
then decided to upgrade to havoc android 11 and installed the from but there were too many issues
so I decided to go back to my oxygen rom. went into twrp reset the device and it went into a boot loop
At this point I could go into recovery so I mounted a USB drive and flashed the stock Oxyegn OS 10.3.11 again
Now I cant go into recovery anymore and the phone does not start up other than into the menu mentioned above.
Can I get some advice please on the steps I need to do to get my phone working again
Thanks
