ROM / Firmware/ Brick Recovery for 7" Android Head Unit AC8227l YT9217 YT9218 1/16GB

Thanks everyone who contributed in my effort to fix my bricked device. Here is all that I have found useful in successfully reviving my device.
The files shared here are the ones that worked on my unit (see specs and pictures below) If your device is different, it may or may not work.
If the device has dedicated radio chip inside, the Firmware number will show as YT9218, if no radio chip, then it will show as YT9217
Note: if your device is not bricked, Make a full backup before trying another firmware.

I hope it helps. (donations are always welcome ):highfive:

Memory dump:
firmware 20181222 HiFi: (Link) (thanks mazepa2000) (May 2019 update below)
Rooted TWRP firmware 20190523 HiFi: (Link)

Preloader (Boot_1) from other Similar Firmwares: (Link)
Download the one similar to your device's version.

Firmware via flash tool: Rooted TWRP 20190523 (Link) Thanks Maxkir
(You may need to remap side touch buttons in Factory settings (code 8888) -> Touch settings -> Click start -> Name of the button -> The button itself ->Repeat for all the buttons -> close -> ok).

Firmware for YT9213 Device: (Link) (Thanks pajurpl)

Update / Upgrade Files USB flash drive:
Firmware 20190522 HiFi: (Link) (Thanks foxgiggle , iSevenAuto)
Firmware 20190906: (Link)

MCU 3.1 (Link)(Thanks foxgiggle )
MCU 2.8 (Link) (Thanks lemmon and foxgiggle)

Memory Dump Procedure via flashtool:
(Memory dump is only needed if you need full recovery from a backup. Otherwise you may only need to do the next part.)
Download and install MTK drivers. (Link)
Load scatter file and preloader (Link) in spflashtool. Press Ctrl Alt V , then go to Window and select "write memory". In file path select "user", in begin address put 0x0, In Region select the partition named "EMMC_USER". Hit Write memory. After that plug in the usb cable (connected to usb1 port). If the device is not detected, you need to power it on. If still not detected then you might need to short the two test points (see picture) (without power this time) and then plug in the usb cable. Remove the short when write process starts. Check if the issue is fixed. If its not fixed, then do the same to write boot2 and boot1 partitions as well. You may need to download Boot_1 specific to your original firmware from the link above.

Uploading Firmware (full or parts) via flashtool:
If you are uploading the firmware available in parts, you only need to upload "BOOTIMG" and "ANDROID" (SYSTEM).
You may also need to flash "RECOVERY". Remember to uncheck the preloader. Here is a nice instructions file. (Link) (thanks Maxkir)
There is more info and firmwares to chose from at 4pda forum.

Update / Upgrade Procedure via USB flash drive:
Copy the zip file (do not extract) to usb drive or microSD card, (formatted by SD Card Formatter). Connect to usb port 1 or 2. Go to Car Settings, System info. Click Android Upgrade.
--OR--
Extract the zip into a folder named XYAUTOUPG into the flash drive or microSD card, connect to usb port 1 or 2 and then reboot. Upgrade should start automatically. You might need to try with different USB drives or sd cards. For some reason this only works with certain usb and cards.

MCU Upgrade Procedure via USB flash drive:
Extract the mcu file into flash drive or microSD card. Connect to usb port 1 or 2. Go into system info and update mcu.

Make a Full Backup/Memory Dump:
Open SPFlashtool, Select Memory Test Tab, Select only RAM Test (uncheck the rest), push start, and connect the unit. Save the information appeared, in a text file for later. (Read above "Memory dump procedure" for the usb connection setup).
Now go to ReadBack Tab, Double click on empty space next to tick mark, Select a folder where you want to store the dump file, and Type a name for the dump file you are going to creat, (ie. Boot_1, Boot_2, USER). Click Save. In next window "Readback block start address", select the region you want to make backup of (ie. EMMC_BOOT_1, EMMC_BOOT_2, EMMC_USER).
Start address is 0x0000000000000000
Length copy and paste from the text file you created earlier.
typically for Boot_1 and 2 the length is 0x0000000000400000
and for USER (16GB models) the length is 0x00000003a8000000
Click OK.
Now click on Readback and then connect the unit via usb cable. and Read process will start.
Do the same to make backup of all three partions. USER will take long time because its the largest partition.

RDS FM Radio:
Radio app with fixed RDS, channel names on buttons and HiFi: (Link) (thanks sjguk)
Copy to FMRadio directory, rename to FMRadio.apk and change permission 764. (or 755 ?).

Channel name Editor: (Link) (thanks mclaught)
install as normal. You may need to install GalaPublicResources. Click top right dots.


Multi Window Mode:
Go to root folder, look for build.prop. Open in text editor. Change the line ro.build.type=user to ro.build.type=userdebug.
If no such line is there, then simply add the line at the end. Save and exit. Go to Android settings, Developer options, look for multi window mode and enable it. Swipe down from the top of the window, Click on recent apps tile. You'll see the new multi window option there.

Subwoofer output Pin:
The default AUX_out pins are for mid range audio and is controlled by Mid slider in the mixer. The subwoofer output is on another pin (See Picture).
it is easy to remove one of the AUX_out pin and install it at the Sub output. this pin is controlled by Subw slider in the audio mixer.


Launchers UI1, UI2, UI4 (Link), UI5 (Link) (Thanks Maxkir)

Boot animation: (Resolution is 1024x600)
eg. (Link)
The animation preview didn't work for me, but I installed it anyway and it worked fine.

OBD Dongle Bluetooth Setting:
Open Bluetooth app, Click on settings, tap on the pin code "0000" and type in "1234" instead. Save settings.
Now search and connect the OBD dongle normally.

I hope it helps. (donations are always welcome ):highfive:

O método de unidade flash USB não funcionou para mim, o dispositivo não detecta o USB durante a inicialização. Eu tentei de tudo, conectando os pontos de teste, apertando o botão de reset etc. sem sucesso.

A ferramenta flash SP parece funcionar, tentei fazer upload de várias ROMs disponíveis, apenas essas três foram carregadas com sucesso,

full_8227L_demo-userdebug 6.0 MRA58K 1534513814 chaves de teste
Заводская прошивка под флештул от 09.11.2018 UI1 с переводом
20181224 TWRP ROOT перевод и эквалайзер от ноябрьской

mas não ligou o dispositivo. O dispositivo liga, mas eu obtenho uma tela preta (retroiluminada). O que mais há para tentar?

hello good morning, I have the same problem, after resetting the factory it starts, displays the car logo and then the black screen is on, did you solve it? I tried some roms on the pendriver but it didn't boot, can you help me?

 

[Nilalisson]

No final, consegui fazer upload

Depois de algumas horas de tormento, meu amado rádio conseguiu me colocar de pé.
Eu carreguei com o pré-carregador selecionado porque eu tinha um rádio de tijolo (tela preta) e ele não ligou. Se o seu rádio não tem tijolo, desmarque o pré-carregador ao baixar o firmware.
Nenhuma fonte de alimentação necessária para o upload, apenas usb (4 pinos)
Abaixo o firmware completo com pré-carregador e pacote de firmware completo YT9213A_00009_V001_20191126 pronto para ser carregado pela SP Flash Tool.
Abaixo, as instruções de upload são registradas rapidamente.
Eu vi que alguém acima também estava procurando um pré-carregador para que este modelo fosse definitivamente útil.

Hello. I bricked my Unit FF-5000 Alps AC8227L (see attached photos) and now my unit just power on, but display remain black as in the picture. I use SP Flash tools and I deleted all (I use format All + Download). But the file I have want to write is not for my unit, and now the system is bricked. Any help please!!!
I'm desperate, because I try all I know, but no result.
If anyone have these file ( pgpt, pro_info, nvram, protect_f, protect_s, seccfg, ) for making device to boot, and Preloader, lk, bootimg, arm2, recovery, sec_ro. meta, logo, misc, logo, metazone, etc... I will apreciate.
Unit seems to react on SP Tools, not want to update from that 2 file on usb/sd card (dboot.img and update.zip)because do not detect usb drive, but the red bar on SP Flash Tools go to the end, and after that, I got 4032 error. On device manager my unit it see as MediaTek USB Port (COM7).
HELP PLEASE!!!! Thanks.

Hello everyone.

Is there any new version of android for these models?
I searched for android 10 or 11, but some files are empty, or scam probably.
I am using android 9 at the moment
