Как прошить китайскую магнитолу 8227l demo
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.
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)
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 bought a car with what appears to be the exact same unit, but the Android version is newer. Is it any point to upgrade?
Here's what mine says:
Android: YT9216B_00002_V004_20190906 (only the date differs from video)
Android os: 9.1 XY AUTO: 3.1 (8227L).
The firmware in the video aparantly has a lower Android os version? But the other is newer? I'm a bit confused. Will this be a downgrade for me?

I have the same setup as like you but while I’m opening the device settings then I’m not getting that Android Upgrade option. As below screen I’m getting and in-between many errors like google service stop working, keyboard is not working, Play store service stop. But still I’m running this system. As of now no other way. You know even while taking reverse my car camera display sudden off any system getting stuck on Android logo till 10-20-30 minutes. Then I’m clicking on RST button then it’s again its working for a while. Too much frustrated from this issues. Please refer my below attached snaps of my system(2GB/32). Please refer this ZIP file.
Requesting you to please suggest something stable options. Thank you very much.

Hi Rahul,
I have checked images and as requested here is the latest firmware.
if update is not detected format usb drive with Fat32 format and then just copy firmware zip file and paste in root directory of pendrive. For assistance do check the video. If still the android upgrade button is disabled then try another usb port.
Also try factory reset and then update the device.
Update at your own risk.
click video link and comment. im not a developer i just listened to the amazon sellers directions and then searched 8227l in google and found a bunch of files, then tested them and now i want to pass the info on.
tp the guys asking if itll work?
i dont know you gotta test it like i did. they worked on my unit. and the files i donloaded came from other style stereos with android.
i just generally think they are all same firmware if it look similar to actual stereo design and ui .

Yes u can ( always do at your own risk like me); but use one of the touch only files. I can't upload pictures yet but i tried to post a screenshot of each firmware look. If its 8227l firmware it should update/flash.

Ok i may try to flash it this few days. Btw the 8.1 is the go ver or just 8.1? What is your recommendation to install 8.1go or 9.0 which is smoother and better?

They both looked very smooth even when running on my stereo. And i have a touch & button stereo it worked flawlessly no lag no glitch.
Only error was for the firmware being for touch screen only

Hello, I would like to know if this type of software has in some menu the option of autosleep to program that it turns off completely and does not remain in standby, in other Android it exists but here I do not see it. Can this Android 9.0 image be flashed even if it now has 8.1? Is it official or is it rooted?
thanks

Hi guys! I ask for your help, a few days ago I bought an android radio unit on aliexpress, specifically the Junsun brand, with these characteristics:
Its my first time with an android radio unit and I am very lost, I would like to know if I can change the firmware or update it, the one that it brings is very limited and does not let me change the brightness of the device or bluetooth functions.
Thank you for support!

i have 8227L with DSP will it work with this
This is for those who have a ( 8227l ) android stereo and are looking for the update file zip. Also the mcu in the about phone menu should begin with ts . I have 5 files from jby tech, they are the Amazon seller of my hizpo android 8.1 stereo unit. From lots of research and emails to the company, i found that these Android stereos come in many brand names but run the same 8227l system. Another company with the same unit is joying but the device name is different along with the entire UI. Please do be sure you have a 8227l unit before proceeding. Other updates for other brands can be found on google and xda forum. I will try to remember to put link for xda forum. Below I have listed 2 groups of files. One is for touch screen only android stereo and the other is for touch screen with volume knob. Please choose according to your type of stereo. And follow the steps below exactly.
1. Download proper zip for your device.
2. Extract the 2 files from within the zip folder.
3. Copy & paste the ( .bin ) & other file on to a blank sd card or usb flash drive. Make sure these are the only 2 files on the sd card or flash drive.
4. With stereo unit powered off insert the sd card or usb flash drive and power on stereo. (Note some units will recognize the file immediately during boot, and others will prompt you after loading main screen. If unit does not recognize it, power off for 40sec and when u power on tap the screen in middle repeatedly with finger until the word "detected" shows in green. If it gives a message in red saying failed please check you have good download copy and have followed the instructions exactly. Will answer questions as i am able to.
All links to files and sites mentioned must be copy pasted. Im not able to attach external link yet.
The files below this line are for android6os,7os,8.1os 8227l units with a volume knob
Here is another version for this unit that is stock Android 6,7os but felt like it had a low resolution not for certain, but is safe to install in case base version still isnt a match for your unit:
The files below are for the "TOUCH" only Android 9os 8227l units with touch back, home, vol -/+ buttons.
*** I have installed them on the non-touch unit and it will work but not allow volume knob to work, and will display " Activation code does not match " ***
I have a 8277L with Dsp, will it work with this one.
Внимание! Все дальнейшие действия вы выполняете на свой страх и риск!
Этап 1: Подготовка
Перед началом прошивки устройства нужно произвести некоторые операции: узнать его точную модель и загрузить файлы обновлений, а также подготовить флешку или карту памяти.
-
Первым делом следует определить конкретную модель вашей автомагнитолы. Самое простое решение этой задачи заключается в использовании настроек девайса – откройте его главное меню и тапните по соответствующей иконке.
- объём – не менее 8 Гб;
- файловая система – FAT32;
- тип коннектора – желательно USB 2.0, который медленнее, но более надёжный.
Этап 2: Прошивка
Теперь переходим непосредственно к прошивке магнитолы.
Решение некоторых проблем
Рассмотрим возможные сбои, которые возникают в процессе выполнения инструкции выше.
Магнитола не видит флешку
Если устройство не распознаёт USB-накопитель, выполните следующее:
- Проверьте работоспособность носителя – возможно, он вышел из строя. При обнаружении неполадок просто замените его.
- Подключите носитель к компьютеру и проверьте файловую систему – возможно, вместо FAT32 вы использовали что-то другое. В такой ситуации просто отформатируйте флешку в нужный вариант.
Флешка видна, но магнитола не видит прошивку
Если гаджет не может распознать файлы обновлений, причин у этого две – вы загрузили данные для другой модели или же распаковали их не полностью либо не в корень флешки. Решить проблему можно так:
- Отсоедините USB-носитель от магнитолы и подсоедините его к ПК либо ноутбуку. Проверьте местоположение файлов, их количество и размеры.
- Также, если присутствует документ сверки хэш-сумм в формате MD5, сверьте данные с его помощью.

где ссылка на прошивку?
Здравствуйте. Возможно глупый вопрос, но система на скриншотах это обычная оболочка андроида 8.1 или, как например у Самсунг, оболочка конкретного бренда? У меня такая же картина на ГУ. И очень интересно, до чего можно обновлять данную сборку, а на чем она точно не поедет?
Как с завишего состояния его прошить или же востоновить до заводских настроек
Некоторые устройства можно перезагрузить путем одновременного нажатия (и удержания) нескольких кнопок, чаще всего это включение и одна из кнопок регулировки громкости либо же включение и вызов дисковода (если он есть, конечно), следует попробовать оба варианта. Возможно, на вашей модели перезапуск и/или сброс выполняется иначе, и логичнее всего будет самостоятельно поискать эту информацию. Просто введите в Google или Яндекс запрос вида *автомагнитола производитель модель перезапуск* или *автомагнитола производитель модель сброс настроек*, найдите официальное руководство и воспользуйтесь им.
Далее действуйте на свое усмотрение: если сброса настроек будет достаточно, задача решена; если нет — пробуйте снова прошить магнитолу по инструкции.
Нечаянно убрал яркость на дисплее андроид 8.1кардрокс.при загрузке экран загорается, потом ничего не видать. Что делать?
Программирую кнопки руля. Работают некоторое время . Потом отваливаются . В настройках руля магнитолы настройки стоят, а кнопки не работают. Приходится заново перепрограммировать . В чем может быть причина?
