MTCE px5 XRC Unit searching for stock ROM Android 8.0.0 (OREO)

Hi Guys,
i am a new owner of a MTCE Android Head-Unit and interested in upgrading my rom to a custom rom. Especially in hal9k, but I'm open to that.
The problem I have is, I am a little scared, that I can never go back to the stock rom, if anything is even worse than now. And I just buyed it, and could easily return it till 2 weeks from now. If I flash a custom ROM and cant go back, I'm sure, I can't return it easily.
Therefore I am searching for the STOCK ROM for my unit.
So far, I didn't found it. Maybe I was just searching at the wrong section. Or it is burried deep down in a long thread. So if someone could help me finding it, it would be very nice.
Build-number
px5-userdebug 8.0.0 OPR5.170623.007 eng.hct.20180126.155501 test-keys
MCU:
MTCE_XRC_V2.94_1
Thank you in advance.

I'm in the exactly same situation.
Bad luck for us. I didn't find any XRC stock rom, and my seller is just ignoring my messages.
If you finally find something please report. I will do the same.
Have a look here: https://forum.xda-developers.com/showpost.php?p=75173763&postcount=2
There are a list of stock roms that supposed to be totally compatible among every PX5 model.

i got v7.3 to work lagfree, on miui 12 eu stable, the patch "com. qti. chi. override. so" is supposed to be copied to vendor/lib/hw..instead of system/vendor/lib/hw (actually this directory doesn't exist in miui 12 eu stable), if you are using twrp to copy the file, remember to mount vendor first

Go to Settings>Aux cameras and enable wide angle lens. Then there should be a button in the viewfinder to switch lenses.

60fps video does not working for me, any ideas?

Hello, why selfie cam is so slow on taking pics?

Dasaita Max 6 update and Android auto

I have the PX6 Max6 direct fit in my 2012 tundra, everything worked fine but i was trying to update using the download in the thread
Dasaita - Latest MCU and Updates for Rockchip PX5 Octa-Core 2G RAM 32GB and the updates below.
I did the following updates for max6 and the car play dongle
for the max 6 update noticed nothing different all looks exactly the same and nothing added.
with the dongle it added a new app but when i try to use the android auto the screen just goes black like nothing is hapaning.
this is the dongle i am using

9.0 update
S920 Version : PX30 HCT4_px30_9.0_ota(20191101)
V940 Version : PX5 HA_px5_9.0_ota(20200426)
MAX6 Version : PX6 HA2_rk3399_9.0_ota(20200423)
Carplay Dongle Autoplay APK ：
Any help would be appreciated, im not a computer genus but can get around lol

It's possible the AutoPlayBox.apk posted in that thread is busted. You can try the latest one from Carlinkit here: http://carlinkit.com/filedownload/32844
If that doesn't work, I would go back to using an older version of the MAX6 software. Even on the MAX6 with built in android auto (ZLink), the android auto doesn't work correctly with the 20200423 update. You can find a lot of the past versions here: https://yadi.sk/d/umCvHqCDzHccr/RockChip PX6 Android 9/HA

Configuration of my tablet :

If it's running fast and stable and fulfilling its purpose I would leave it be.
Updates can and do break things.
Pie is a good OS. This Samsung N10+ I'm using is still running on it, deliberately.

You can always upgrade at any time. Be aware of 9's vulnerabilities and take appropriate steps to mitigate the risk. I run Karma Firewall and recommend it, freeware that uses almost no battery. Disable wifi and bluetooth if not used or when not in use.
In general security is not an issue with Pie, it holds up very well.

Redmi Note 8 Pro Bluetooth range issue

I am trying to use the Oppo enco buds with the Redmi Note 8 Pro which is connected using AAC by default. The Bluetooth range when using these earbuds is very low, like 100cm. At first, I thought this might be a problem with the earbuds, so I tested with my MacBook as well as other android device and it works perfectly with everything else. I tried changing the codec via developer options but it always resets it to AAC.
I am running MIUI global 12.5.7 on Android 11.

I don't seem to have that issue. Been streaming music from my redmi note 8 pro to my Harman kardon bt speaker from the other room. 7 meters and a 20 cm wall and don't have any issue. The issue might be with the earbuds. Or with the version of miui you are running. Try downgrading, maybe at miui 12 it handles differently.

Which version of MIUI do you have? While connecting to your Bluetooth device which codec does it use by default?

Actually the bluetooth range of Redmi Note 8 Pro is less as compared to other devices or mobile. I was also using Redmi Note 8 Pro. Mostly in the Pinoy Teleserye I have to transport documents and images to other employees of the office. So the redmi bluetooth range was very teasing me thats why I changed my phone.

Then your phone get F by PE A12 tree. Flash Miui fastboot then use Factory reset in Miui setting to solve that (Miui 12.5 work with almost. If not, downgrade to Miui 12 and do same and check)

All will need to be replaced if you come to Xiaomi service center, even a normal hardbrick. And someone feedback that after flashing new PE, their Bluetooth problem got fixed.
