HELP-ME: Firmware 8227L ANDROID YT9216B 2/16

I'm having an audio problem in the version of my Android HU, I need to change to a current one or downgrade (to 8.1).
I didn't find any firmware in version 2 gb, I tried to install the versions of 1 gb and it causes error
See below for details of my HU. Thank you very much for helping me (sorry for my english)
ANDROID: YT9216B_00002_v004_20190830
VERSION 9.1
XYAUTO: 3.1 (8227L)
CAM BUS 3.1
DDR 2GB
FLASH 16 GB
MCU1: 3.1

I am having the same stereo.
The model details are almost the same as you mentioned for my android stereo.
The issue with my stereo is when I do a factory reset, the system gets hung after showing the "Erasing" android icon and a dead android icon with a Blue exclamation is displayed,
Any fix for this ?

Hi I have made a video tutorial on how to make stock ROM backup

Hi friends,
Have you are observed overheating of touch panel of your car stereo or hangs in your Android car stereo or system not responding or application keep crashing etc.
Then this video is for you. I have done this small modification in my car.
I made a small hole on sides of AC vents such that cool air blows over the heat sink of Android car stereo and two cpu fans of 12V take power supply from same connector.
Whenever the car stereo is turned ON the fans also turn ON and blow cool air over the heat sink to keep it cool.

Hi everyone,

0000
8888
1234
127
12345
1122
112233
000000
to unlock device but all in vein.So would you please suggest me some valuable solution to resolve this problem.some pictures from screen and its panel are also attached here.

Bajwa ji it appears the password is Google password not unit lockscreen password.
Please try your Google account password that you may have set to protect that unit.
It is ac8227l yt9216b unit 16gb ROM version.
If that fits not work then apko factory reset karna padega. But all data will be lost forever.

Sir i could not recall password for that account. Further how to perform factory reset? bcoz screen is locked. So should i go for installation of new software. if so then plz guide how to install it...

Try to connect the unit to your computer or laptop. If somehow you can connect the unit to adb mode then factory reset can be done from recovery mode.

lf A9/10 Custom Rom for 8227L based YT9260LP-VER0.2 YT9213A_00009_V001_202000408

I bought a cheap 8227L based device running android 10
(correction it's android 6 with a few strings replaced so it looks like Android 10 at first glance, dispute already in progress)
So far so good, still quite a bit of bang for a few bucks (minus the fraud) ...
Board images are attached
I was able to read a complete dump of EMMC_PART_BOOT1 , EMMC_PART_BOOT2 and EMMC_PART_USER
(by soldering a pair of cables to the test pin pads (volume up), so that SP-flashtool would intercept preloader that shows up for like one second.
Edit: Was able to extract all partitions except NVRAM and some other, see second post. Apart from that I think I have an emergency backup now. Stock Dump
Now the remaining question: Does anyone have an idea if there is a working A9/10 custom rom around compatible with the device:

I read out gpt infos and confirmed the scatter file from here
https://forum.xda-developers.com/an...-firmware-chinese-7-head-unit-ac8227-t3931863
does match exactly.
Rom and preloader is different though, my preloader has a 0x800h long padding starting with EMMC_BOOT while the preloader found in the mentioned thread starts with MMM8���FILE_INFO right away.
Other issue is that my NVRAM, PRO_INFO, PROTECT_* partitions are all empty in the dump (full readback or partition based readback makes no difference)
Right now I guess I'll stick with the A10 stock rom as every other Rom I found is older anyways

Hi my friend
I bought exactly the same stereo in aliexpress
Because the balance and fader don't work I sent a mail to the seller and he sent me a new firmware for upgrade via
This firmware freezes the stereo 10 seconds later that starts
Im trying with the seller to send me the full original firmware to flash with computer but is very slowly...
He send me a new correct firmware to use but in android upgrade format, so I cant use because I cant turn on normally, if you want i will send you.
Can you send me the full dump of this??? ( EMMC_PART_BOOT1 , EMMC_PART_BOOT2 and EMMC_PART_USER )
Thanks a lot!!!

Helló barátaim!
Kínai multimédiás fejegységem van. Januárban jött, telepítettem, megfelelően működött.
A múlt héten aztán kicseréltem az autó akkumulátorát, és amikor újra bekapcsoltam a rádiót, jelszót kér.
Mostanra rájöttem, hogy ez egy képernyőzár jelszó.
Sajnos ezt nem tudtam, ezt nem kapcsoltam be.
Elolvastam a fórumokat, és helyreállításra lenne szükségem. A leírt módszerekkel ezt nem tudom elérni.
A bekapcsoló gombbal nem lehet kikapcsolni a rádiót. Tehát a power / + VOL kombináció nem lehetséges.
Hogyan lehet elérni ezt a helyreállítási módszert?
Kérem, segítsen, nagyon hálás lennék.

My radio exactly the same as what radio yours.
I half-solved the problem, installed new firmware, and added it.
Tthen when i turn on the radio, it doesn't give a picture, just a black screen.
The side control buttons are lit but do not respond to them or the reset button.
Do you know anything smart?

MCU Android Allwinner T3 P1 Help With it PLS

Hello to everybody,
I am new to this world and have been facing this android car stereo for almost a year and have read many posts about this problem.
I found many answers to other people with similar problems from "ahmed68", so maybe if you are reading ahmed68, please help me.
I have a problem with the steering wheel controls and canbus settings of my Chinese android car stereo. Actually in my system there is the possibility to change the type of canbus, but the selection is a fake toggle that does nothing (and my car type is not even present in the canbus list (chevrolet aveo 2012, GM) ).
Can the problem be the MCU firmware?. Everything works fine for me with this devidce, except this feature for the SWC. Any possible update to fix it?

i have the same problems but with a Dacia aka Renault Logan. I can't use SWC learn function. Canbus is a simple soft . Did you find a fix? I have android10 but i think is a fake.

szia, a következő problémám az, hogy nem látok semmit bluetooth-on és a telefon nem látja a rádiót, mit tegyek? Valaki tudna nekem segíteni?

Sadly it is not. But the same procedure should work. You just need to find the right backup file. I think there are plenty of those threads here.

yes, i think thar are the correct rom and backup . The problem is i still can not get connection between the HU and my. I ´ve checked the drivers many times.
I tried to disconnect and connect the power many times and my pc gets rebooted for security reason.

Best regards

The trick is to start the SP Flashtool progress before you start the device and plug in usb. Because for a brief moment it will be in download mode on boot. Thats at least how it worked on mine. If SP Flash tool recognize the usb connection then it will lock it self in download mode until everything is flashed.

Ok, but i have two doubts.
1 .My usb wire m-m is 3.0? is any problem with that
2 . Can you explain me with details the step in order to get the downloadmode?
I understood first i have to set de SP tool, click in the " play buttom", power the HU and then connect de usb? power on and connect the usb must be at the same time?

What i did is that i had the usb connected. Then just cut the power and add power again. I dont think the cable should matter. If the driver is not right you can have device manager up when you add power and you will for a brief moment see it there so you can update the driver. You gotts be fast though

I ´ve followed videos how to install the drivers and i did it as well. The first time i connected this it´s worked for me because i saw the "OK" green but after that th HU wont boot. No when i power on i only see a short blink on the screen but anything more.
Ah, and i never hear the sound when the usb is plugge (tucutun)
Any more ideas? Did you had the same problem like me?

Oh then i think i am out of ideas. Like i got the USB sound when the USB was plugged in and gave it power. If you dont get that i dont really know

I ve retired the coverheat and I found this but is not clear where the test point can be.
