Hi,

I have a AC8227L headunit too, it have been flashed to change the starting logo to be Dodge logo, but instead it was a complete new ROM i think, the launcher looked the same but the Android CarPlay app have been replaced by a fake spanish app who ask to pay to use and it is impossible to isntall back the original even with .apk its locked, everything is in spanish and the language option dont work even tho i spam FRENCH, all the settings options seem locked and verry limited and its now in Android 11, i tried to download a new ROM from here to flash it again but it dosen't work ( or i made a mistake ) i was looking for a clean Android 13 with a clean launcher where i can add the apps i want and change the interface but and even tho i read this thread i still dont understand how to do, if the .bin is enough or if i need a "bootloader" thing with it to boot ?

I tried to put them in a FAT32 USB key and restart the device with the little hole in the top left but it does nothing, then i tried tro let comrpessed in zip file and load it from the Update Setting but it dosent work ( seem locked even tho the USB key is seen by the device )

Does anyone have any idea how can i install an Android 13 Clean with a good launcher for Dodge please ?
[Android Head-Units] dodo6:
I think the latest is android 8.1 (everything else is fake)
[Android Head-Units] Alpharid:
When i first bought the HeadUnit it was in Andoird 13 if i remember well, and a friend of mine have his in Android 13 too, with the Junsun launcher on it.
[Android Head-Units] dodo6:
editing one line of build.prop takes about a minute. I can also write you android 43 there if you want... or do you want android 19? choose anything. I can edit the next line for you and you can also have 8GB of RAM. I think that the devices of the yt92xx family ended with Android 8.1. The Chinese seller will write anything to make money
[Android Head-Units] Alpharid:
Ok i see, but even tho i still cant boot, i tried 3 firmeware already, comming from here, im certainly doing something wrong or not downloading the ones compatible with my chipset ?
[Android Head-Units] dodo6:
are you sure you have ac8227l? because any android 9216, 9217, 9218 worked for me. only there were problems with the sound, but the android always started. if you have a junsun model, try YT7260/YT5760 (AC8257) all at your own risk

edit:

if you want here is the firmware link for junsun v1 pro/64

https://drive.google.com/file/d/1Qu...w?spm=a2g0s.imconversation.0.0.5fea3e5fZA8C2e

all at your own risk
[Android Head-Units] Alpharid:
Yup i am sure, i opened it and its writen on the chip

i dont have a Junsun, Junsun is the one a tried, i had a Podofo, but its just the label the chinese put, its not a real factor when looking for a firmeware is it ? i think its the launcher or smth like that right ?
[Android Head-Units] dodo6:
ok. I think that junsun, podofo, hizpo are sellers. boards are made by xyauto (carsoft_xyauto), do you have a photo sticker on the board? 9217c and similar? do you want 9216B firmware? hard to advise on firmware, only ac8227 had info

ed:

in any case, do not flash the preloader! only flash boot, system, vendor via sp flash tool. I also do not recommend flash metazone (stores information about the device, settings, image resolution, etc.). Leave your metazone. Do you know what I'm talking about?
[Android Head-Units] dara_0304:
Dodo may you advise me which firemware is ok for my headunit F9212A android 11 v7.39, 1024x600, is there any update for my car unit, I saw on a new page of carsoft.xygala.com ver 8.0 but it is 1024x768
[Android Head-Units] dodo6:
I don't know, but if you don't have problems, let it be. if I'm not mistaken, firmware compatibility: 9212A <-> 9211A <-> 9210A < -> 9213, 9212В <-> 9211В but I don't know if there is a newer version for you. you can try to flash from xyauto but don't flash metazone to preserve the resolution. please note that you do everything at your own risk. and back up people!!!
[Android Head-Units] dex4ever:
I only have the 6-pin USB cable, can I somehow make a backup?
[Android Head-Units] dara_0304:
I saw it in te new xyauto web carsoft.xygala.com that there is v8.0 but it is 1024x768 so I didnt update link couse mine is 1024x600

How can i find the information you asked ?

yeah i would like the to try this firmeware, with a mini tutorial on how to flash it on my HeadUnit please cuz when itried with USb and with SP Flash it did not worked.

Im not sure i know about all you said no, but if i understood well, the things you told me to disactivate, i have to uncheck them in SP Flashtools befor click Download, and set as option Update Firmeware, right ?
[Android Head-Units] dodo6:
I meant the sticker on the board. something like this...
[Android Head-Units] Alpharid:
View attachment 6110675View attachment 6110676

This ones ? One inside, one on the package.
[Android Head-Units] dodo6:
on the first page in this thread there is a backup procedure..backup.. and then via spflash flash boot,vendor,system..make a backup.it's worth it.
[Android Head-Units] Alpharid:
Alr thanks i'll do a backup befor flashing, so i have to check the same square you checked for the firmeware flash right ? or is it insctruction for the backup on the screen ?

also with the pictures i provided are you able to tel me what Firmeware i shall use ?

is it the one u sent befor the stickers pictures ?

( https://drive.google.com/file/d/1Qu...w?spm=a2g0s.imconversation.0.0.5fea3e5fZA8C2e ) ?

If yes what shall i check on SP Flashtools Squares ?

thanks for your help mate
[Android Head-Units] dodo6:
no, it's not a backup... the image I sent is used on flash drives. friend, send me a photo of the sticker on the white connector of the unit. if you don't have photo information about the unit, including the MCU version

[Android Head-Units] Alpharid:
I saw a bricked recovery video when the huy is using flash point methode but i have no flash point to short in the mother board, so i found an other one witheout flash point methode but the guy seem to power his board with USB on his computer and does not explain how, i tried with my power methode and i have no boot after i launch the flash on sp flashtoolsView attachment 6111107View attachment 6111108

May i please have a discord call where i can share my screen and film the device so we can understand what is happening and find a solution please im really lost there and dont even where i am at, i would appreciate it a lot
[Android Head-Units] dodo6:
please tell me you have a backup...it became a brick because you flashed the preloader. I pointed that out. according to the photo, you have a completely different firmware than you searched for (jcac10003). ok, I will try to search for a solution

edit 21:56

ok. you had the device open. did you have these points there? it's a testpoint jcac 10003 2gb ram, I think

if yes, we will continue. if not, we look for a solution further

edit 22:10

download it. this is exactly the firmware you have. jcac10003-oc2-v1.0.90-r9-230906_1049

1.07 GB file on MEGA

mega.nz

this firmware can be installed via sp flash tool. there are also other versions of the firmware. I also have different preloaders. but now it doesn't matter, you need to revive HU
[Android Head-Units] Alpharid:
Thanks mate i really apreciate your help.

no i opned and checked i dont have Test Point i looked verry well there is no test point, how can i do ?

After i download what you sent me what do i do with it ?

Edit : I think i have the test point i just checked one of the pictures i sent and i think i see them, i'll upload it here so u can confirm mate

View attachment 6111164
[Android Head-Units] dodo6:
one point test point..ok.let's try something..run spflash. select all+download format. try to use this scatter and preloader, I'll send you here. nothing else. connect the wire to the HU frame (minus 12v), connect the other side to the test point. turn on the 12v power supply of the main unit... start spflash (hold the wire to the testpoint) if it succeeds, we continue... (if not, try the end of the wire which connect a 200-300ohm data resistor to the test point and touch the test point) please, take note that I don't remember everything well and it may not work for you and you do everything at your own risk as you found out..
[Android Head-Units] Alpharid:
Thanks mate i'll try all that tomorrow and let you know if it worked, one question tho : i have to separate the board from all the rest ? and do i power up the board from the normal entry with 12V ?
[Android Head-Units] dodo6:
do not separate the boards, I have never done it at testpoint. Yes, connect the HU to the normal 12v input
[Android Head-Units] Alpharid:
View attachment 6111402

I tested the wire and i have minus 12, i pointed only the test point you showed in the picture

View attachment 6111403

The scatter file load a lot of things to download even tho they are not present on the folder ( there is only the preloader ) so i cant chose the option Format All + Download.View attachment 6111405

I tried anyway with only Download option, but this is the result.

View attachment 6111408

So i edited the scatter file and set to false all the other sys, and let only preloader.

View attachment 6111416

But its the same error message.

This is how the HU is powered Up and connected to the computer ( 4 pin usb to usb C on the computer )
[Android Head-Units] Alpharid:
View attachment 6111418

I also tried to do it manually step by step, format the chip, then write lemory with the one u sent me, it is the same message at the end, what does it mean ?
[Android Head-Units] dodo6:
Do you have a little blue LED on your board? Does it light up when you connect HU to the PC? (without 12V power supply)

ed:is there a sound (usb connection) after connecting to the PC? I will also send you jcac preloaders

preloader_JCAC10003.zip

drive.google.com

a dalsi
[Android Head-Units] Alpharid:
No blue led, but i have the peripherical sound when i power up the HU ( while i am Connected and i press the Test Point )

What are those JAC ? Shall i try the same process with them ?
[Android Head-Units] dodo6:
it's good that you have sound. jcac you have firmware, so try one of them. you can try to select firmware so that you have the option formatall+download, but it will replace the preloader from these. sp flash start only when you touch the testpoint and a sound is heard. you can also try it without 12v, just connect the HU to the PC (if there is sound connected to the PC even without 12v)

Again the same message about DRAM, i have bo clue what it can be.

Thanks again for all your help mate
[Android Head-Units] dodo6:
there is a lot of information (see google and youtube, but you probably searched) that error 4032 means a faulty preloader. I have another jcac10003 firmware, but it's older v.1.0.34, try

JCAC10003-OC2-V1.0.34B2-210903_0704.zip

drive.google.com
[Android Head-Units] Alpharid:
Yes i searched but i found too many possibilities, some even says it can be hardware, that is why i launched a Memory Test, i tried to find a way to be sure where the problem come from but nothing on youtube / Google or i am using the wrong keyword for my searches.

Thanks i will try again with this ine tomorrow and see if its good.

Is there some driver i need to have on my computer to do this ? I only have Sp Flashtool and the preloader that i try to put, nothing more, i saw people on forum talking about MTK something drivers or Wwr but i dont understand if it have something to do with my case
[Android Head-Units] Alpharid:
I tried this one, same error message.

Can anyone with the same board as me send me a backup please ? I cant find any other solution
[Android Head-Units] Alpharid:
How can i know the exact reference of my board ? Si i can search online in anyone shared a backup for that exact model ?

Thanks again for your help
[Android Head-Units] dodo6:
you must have the MTK all in one driver. Be sure to install it. Maybe it would already be resolved. I understand that you are getting lost in it, but keep your head up. download the drivers. I'll give you some

MediaTek+SP+Drivers+v2.0+signed.zip

Посмотреть и скачать с Яндекс Диска

disk.yandex.ru

You don't need wwr. I sent you what it is used for. If you are interested, you can learn to use wwr. Here is a brief description of what it can do.

-The program works with ROM files (loaded from the device using the SP Flash Tool) based on MTK processors.

-Extracts Preloader.bin from ROM file dump.

-You can cut out a specific segment of a part of the read memory.

-Split ROM file into parts based on Scatter file.

-It searches for PMT, PGPT (SGPT) sections and creates a Scatter file based on the information from these sections.

-Calculates section names, their beginnings and lengths from Recovery_log.

-It works through ADB. Creates backup copies of partitions (if you have root rights).

-Creating a scatter file for rooted devices on the MTK platform. Backup the firmware of all devices.

-Cuts unnecessary sectors (spare) from memory dump to read from NAND phones.

-Show EXT4 partitions in ROM file itself, extract files (only files) from EXT4 to ROM.

-Creation of empty EXT4 partitions according to given length, possibility of conversion to sparse image.

-Creating empty sections or files filled with zeros or random numbers.

-When you open the ROM file, you will immediately see the GPT, PMT, MBR partition table.

I understand, this is unimportant information for you, but maybe someone will be interested...
[Android Head-Units] Alpharid:
All right thanks a lot, i'll try to install the drivers u sent me, is there other i need to find or the ones u sent me are enough ?
[Android Head-Units] Alpharid:
I tried but nothing change, i also found this video :

He got the same error, and after uploading his driver it work, but i dont have the same MT ah him in sp flashtool ( i dont know what the MT thing is, is it the device nametag ? ) mine is MT3367, the guy dont share dowload link of the driver he used and i could not find them even when y type the exact same name.

But my peripherical COM 6 dosent ask for any update like his does
[Android Head-Units] dodo6:
MT3367 =mediatek3367 (designation of the chipset) you can also try other MTK drivers if you find them. I'm starting to worry that you missed something at the beginning. But we're not giving up. I would try to uninstall the sp flash tool drivers, and first install the drivers and connect the HU to the PC. I will send you another private message
[Android Head-Units] dodo6:
there is another topic. have you tried this firmware directly on the usb key?

[Android Head-Units] komoadam:
Hi everyone!

I have a Chinese head unit with AC8227L chipset (ESSGOO Brand) and it is broken. only the blue led on the machine is on. I've tried the test point and flashing the firmware in this thread with the flash tool, always getting the DRAM_FAIL(5054) error message, the same as the problem above.

Do you have any suggestions for me?
[Android Head-Units] Emilson:
@komoadam write post in English or at least use a translator to translate what are You writing.

so what are you flahing there?

Acording to some person from 4pda,

you can read the models according to the numbers in 'car info':

_00012 - 9216BJ/CJ

_00026 - 9216С

_00020 - 9212B/11B

_00017 - 9212A/11A

_00027 - 9210A

_00028 - 9210В

_00002 - 9216B

_00006 - 9260

so from Your screenshot it looks like you should dowlnoad the firmware for 9211/9212 models.

if you have your own backup copy of the 'preloader.bin' file, use it.

if not, I have the 9211/9212 board version so You can try my preloader from attachment.

Open SpFlashTool in 'Download' tab and select 'format all + download' option.

Use 'scatter' file from package of 9211/9212 firmware that You downloaded

if you have your own backup copy of the 'metazone.bin' file, use it.

If not, use some 'metazone.bin' file from unit with 1024x600lvds screen.

Make sure the Spflashtool file list is fully filled and selected.

Ps. if your unit is detectable without using testpoint, it means your preloader is still ok so you can still make a copy of your original preloader and metazone via spflashtool. (if you sure that you didn't overwritten them yet)

Good luck
[Android Head-Units] dodo6:
this should be somewhere above as a general guide. excellent! I would also write that everything you set on the unit is stored in the metazone, therefore it is not recommended to use someone else's metazone (and not at all with a different display resolution) as well as a preloader - if you use someone else's and it is not correct, brick the unit and then restore through testpoint and searching for the correct preloader. before all that, find how to back up and back up. help will be faster
[Android Head-Units] dex4ever:
Guys, I have the 4 PIN USB and installed all drivers (following the video tutorial), but the computer doesn't detect it, and when turning on the android head unit normally as if it were going to be used, it makes some detection sound in Windows but I didn't see any change in the drivers and nothing happens in SPFlashTools, any tips on what to do? I saw some posts about having to do a testpoint to detect it, would it be just that way? I wouldn't want to have to remove it from the car.
[Android Head-Units] dodo6:
That's ok. If I connect my head unit to the PC, it keeps connecting and disconnecting the USB. And all around. In SPFlash Tool, I select the firmware, give it a start (in SPFlash) and then connect the unit without power, and it detects the unit and writes the firmware. I'm not sure, but if you connect the head unit to the PC before SPFlash, Windows detects the drive on the basic USBMediaTek (COMXX) driver. If you run the Flesh firmware in SPFlashTool, Windows will switch to the SPFLASH MediaTek Android driver and write the firmware (ANDROID MEDIATEK VCOM - Virtual COM port) if it does not detect when connected to a PC nothing, you have to use testpoint so that Windows recognizes at least the basic driver (USB com mediatek) if I'm wrong, correct me people. peace.
[Android Head-Units] komoadam:
Sorry for my reply before, the translate is on. already edit that

So, thank you very much for your response

My headunit hardbrick, only detect use testpoint. but i confuse to choose the type, because the model is so different from the other (Q92-A4)

I will try your suggestion to use 9211/9212 firmware, and use the preloader you gave to me

I dont have any backup for my headunit, so your suggestion is my only hope...
[Android Head-Units] komoadam:
Thank you

Thanks for reply

My head unit already brick before i backup anything

Just a photo of the model

Confused to search the same model (Q92-A4)

Maybe any suggestion for my problem?
[Android Head-Units] dodo6:
from my search it is 9212.I could also be wrong
