UIS 7862 & AYI mcu questions

Update: so i tried my luck and updated my headunit MCU, and luckily everything went smooth & good
but nothing have changed in canbus settings. Anyway I'll attach that working mcu for IYING headunits.
Hey there,
I've bought an after-market screen for my MG HS in the package of "joying" but after inspection i've found that it has an mcu of a company named "AYI" with same specs of joying screens. I've found it when flashing FW upgrade of joying and a yellow bar showed that fw and mcu does not match
For instance, most of my car settings through screen works good (like AC and rear cam, locking srttings) but i miss lots of other settings from my original screen like ambient light settings and trunk opening degree ... etc
I've flashed a custom rooted rom from 4pda for 7862 and it works flawlessly, also i've found mcu that should work for AYI but still afraid to flash it to avoid hard-bricking my device ... finally these are my questions:
Does MCU upgrading can affect settings for car canbus that is showing in factory settings menu [ATTACH type="full"]5386565[/ATTACH]
Could anyone assure that my screen's mcu belongs to AYI

Finally, my screen is allegedly running Android 10 with 6gb of ram
Sorry for my bad english

Before flashing another compatible FYT firmware to your model, you should have changed the [ro.build.fytmanufacturer]: [43] to the value of your manufacturer. That is described multiple times here and on 4pda.
That causes the yellow bar and some of the settings not working correctly.
If you still have your old firmware, then check that value and modfy your Joying firmware before flashing.

I've solved this problem already but i used this code in the config file of the rooted & modded firmware:
FYT = 31 ro.build.fytmanufacturer = 31 MCU AYI IYING DATONG TECHNOLOGY ANTWING
thanks anyway ❤

updated my mcu and here's the new mcu info
my screen is called IYING

I have problem on UIS 7862 & AYI mcu too. I'm flashing FW upgrade of joying and a yellow bar showed.
I tried to change ro.build.fytmanufacturer = 31 but it stuck at google logo.
Can you help me?

Is not the operative system, is the hardware.
For radio you need to use an amplified antenna (Amazon) and for sound if you don't have external amplifiers you are lost.
All the cinese "toys" had theese problems.
I have a SC9853i headunit 4/64gb and fortune I have original external amplifiers, so no problems, the radio is a sh....t.
I rooted and I modify a lot af configuration, it don't resolve, it's a cinese sh...t.
Go to icar.vietnam forum and you find how to root OWNICE C960 (tested, it work)

Please help mi identify hardware - Uckazy 8259l HU (Alps 825x_pro) for bmw e70

Hi,
I am so confused, and would really appreciate help. I read numerous threads and comments, but not able to understand the unit i have.
I bought on aliexpress Uckazy 8259l model for bmw e70, which seems to be Alps 825x_pro according to CPUZ.
Unit so far is working ok, expect for really bad internet speed (mobile hotspot even tho i have fast internet on my phone), audio buzzing on AUX and random reboots when multiple apps are running (not frequent).
I used CPUZ (that always crashes after 10 seconds) and Inware to get these specs:
Brand: Alps
Product: full_825x_Pro
Model: 825x_pro
Resolution: 1920*720 (aliexpress specs states 1280*480)
Size: 12.82" (aliexpress specs states 10.25")
Hardware: AC8257V/WAB ( i was hoping it is 8259 as model name suggests)
Ram: 6gb, ROM: 128gb
Android 11, API 30
Needles to say, aliexpress seller support equals zero. No communication except sending user manual.

"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
I am hoping someone can help me figure out the following:
is this Mediatek, Snapdragon, PX, somethinge else?
Is Alps known Chinese manufacturer that others just rebrand? Is this unit same as JunSun V1? - hoping to understand this, so i can focus on existing threads on XDA
Is the firmware the latest - not sure how to check and which can i use in case upgrade is needed (e.g. can i use JunSun firmware)
CPUZ says it is API 30, did developers do something to fake it or i can be sure i have android 11 unit?
Should i trust screen resolution that CPUZ and Inware are displaying or could this be incorrect info?
I aim to change launcher, and add custom boot animation/logo, but want to understand specs first
Thank you in advance for your help!

.

Does anyone can help us ? Thanks for advice

I have a similar device for bmw f10. I have an MCU update (4 + 128 is an update of the device itself, here you need to know your parameters) and there is an OS, it's just an update of the android system here on the forum there is version 1.94, I have 1.97 (it allows you to enable the ID8 interface)

It's an odd ball unusual chinese origin headunit...

thank you. I have a 4+64 device.
It seems like 1.94 is not stable. Did you install 1.97 and it worked? Could you send me an information about the seller so I can get in contact? thx a lot

here is the link from whom I bought from, as I understand it, the OS update for these devices is almost the same for all of them, the only difference is the MCU. The seller just sent me the wrong update for the MCU (sent 4 + 128, and I have 8 + 128) and now 4gb works for me instead of 8gb. so I'm looking for someone who has an MCU XRC 8 + 128

ZLH_ID8_OS_8581_1.97 ONLY FOR BMW !!!! MCU: XRC and ZLH (I have MCU XRC everything works well, I did not check it on ZLH)

Android 10 and up AC8257 mcu stm32 vertical screen firmware need

Hi all
ive been reading and looking for a while a firmware based on this unit but ive been unsuccessful. Ive found various firmwares out there, but all are for landscape units.
If someone has or know where i can find a firmware for this unit, please let me know. i tried pda, and various threads(xy, px6, etc) in this forum and found nothing worked cause even though those firmware are base on ac8257, the MCU is different. Some has the correct cpu and mcu but are for horizontal or landscape unit.
i tried to modify the screen orientation via adb and ro.sf.hwrotation, but it doesn't work on latest android . There is another methode editing and xml file, but it looks too complicated for me .
The unit is 4-64gb 768x1024 resolution.
HARDWARE info b200 core 8
Thanks in advance
