Thank for this solution, but where can i find the latest firmaware MX Q-4k RK3229 (6.0.1)?

I guess I did something stupid...
Hi all,
First of all, I have managed to boot into recovery mode and got that menu screen, where you have the wipe data/factory defaults and wipe cache partition.
My stupid thing: I did both... (both cache and data /factory defaults.
Now, I've followed dnbsoundsgo0d guide, but my device is not being recognized by the tool... I'm currently downloading an MXQ_4k_2017.ZIP file I found for the device, but, I'm wondering if by putting this on an SD card, if I will be able to update it without connecting to a PC.
Any word of wisdom is highly appreciated. Thanks!

BMW Head Unit Revive

Hello to all
I have a BMW specific head unit running Android 8.1 and px6 processor.
The unit that i own is that one :
https://www.alibaba.com/product-det...l?spm=a2700.7724838.2017115.89.4e3cf8c9o0r9Dr
After performing a factory reset from android menu everything seemed ok.
Fresh start.
After leaving the car for some hours and come back , after start the ignition the head unit saws this ( photo attached )
After reading so much i see that the unit is in recovery but since there are no physical button except e reset hole i cannot move into the recovery and select any of the two options.
I tried to install an external usb keyboard but it is not recognized when restarting the unit with the keyboard hooked up.
I tried to install an external usb mouse that is recognized , i can move between the two options if i long press a button it highlights the option but does not give " enter " command.
Seller send me the firmware file tha is in .zip format so i cannot use the sd card tool .
I run out of options at the moment .
Can someone give a hand on this?
The best thing is have this zip file to img file , make a bootable sd card and start from there.
Is that possible?
Thank you all guys !
I attach some other photos of the board if you have any idea.
I opened searching for the C17 ic to do the shprting thing but unless i am blind i cannot find it

Ok, in order to update you will need to name the zip as "update.zip" - that's how i got mine to start.
Also you need to format the SD-Card fat32 and make sure it's empty when you copy the Update.zip file
The other option is to go in recovery but you need to find a working keyboard, for example a Logitech K120 for example works well with mine.
Try both USB ports, and try to cut the power completely when you restart and switch the port.
If you can't get a keyboard to work it's pretty tricky.
You will need to unsolder the small resistor shown it the picture, and bridge the connections next to it. (Don't loose it, you will need to put it back after flashing!)
After that you have access to the OTG, and you can use ADB - USB.
not sure it will work as expected in your case, because the unit is a bit different but if all else fails and you don't care about warranty, you could give it a try.

Thank you for your reply
Well i managed to connect a keyboard and try both options
1) try again
2) factory reset data
in some cases the unit boots lets me play with it make adjustments etc.
But after a full reboot unit is unresponsive again and starts again the boot loop cycle.
After full reboot unit complains that the code i entered is correct but files are damaged and needs full factory reset.
I press the button to full reset but it stays forever in BMW Connecting screen.
The thing is that Android 8 has not .img file to use SD card tool to make a bootable sd so i need to get to recovery.
It has zip file that means OTA so i need recovery.
I do not have success on that.
I think that the SoM is corrupted and i do not know how to fix for now.
Any ideas for that?

If you can get into android some times, then do the following.
Try until you are booted in android.
When you manage to get in android, depending on where you play with the unit, try to have it connected to wireless, and with a laptop on the same wireless network.
Then, install Terminal Emulator on the unit.
Open it and try the following commands;
setprop persist.adb.tcp.port 5555
setprop sys.rkadb.root 1​Then, on your laptop install adb, and connect to the unit using ADB connect xxx.xxx.xxx.xxx (xxx... is the ip of the unit)
Once connected you can run the adb reboot recovery command to get in recovery(make sure you have the keyboard working)
Btw, you don't need the sdcard to be bootable.
Try to have the zip file you received directly on the sdcard. Should be PX6.zip, or update.zip, have them both.
Also if you have it on the sdcard when it boots in android, it will detect the update, and you can flash it directly from android.

I will try that next time it will boots to Android .
The file that the seller send me was px6.zip
I will try both of them.
You mean try them on boot correct?

Have them on the sdcard all the time, and the sdcard connected.
once you manage to get in android, it should pop up a message with the update

i did that with a usb drive.
Update gone smoothly after request to remove the usb drive the unit boot up correctly but in the next full restart i had all the symptoms again.
I thought that you mean to have the files before boot and it will detect update before going into android.
I tried booting with sd card mounted with px6.zip and update.zip inside
It gives No Signal in every boot even with one of two files inside.
and for sometime now it does not boot to android at all !!

Sorry to invade your thread but I have a similar issue about updates. I have a PX6 unit from AVIN and they have released 2 updates for the unit but they just REFUSE to start. I have followed their instructions 100 percent and it recognizes the USB stick in either USB port but the updates don't start. I've tried multiple USB sticks and nothing works. Their support is worthless. Is there a way to launch the update manually?

hello, how can i get recovery mode??
I try whit reset buttom, touching with 5 fingers.. but nothing

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

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 )

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

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

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).

All relevant info about ROMs and flashing you can find in top header of this russian forum.
Look at the spoilers in the gray header layer and use Google translate to understand what is written there.
There are 3 ROM versions for the 8227L based head units. I downloaded and installed the oldest of the 3 (rooted and TWRP IMG included). Copy all files from the RAR to a flashdrive in root folder.
Turn off the head unit.
Connect the flashdrive to USB 1 slot of the head unit.
Turn on the the head unit.
The install process starts immediately after turning on.
It takes about 10 minutes.
When install process is ready, turn off the head unit.
Detach the flashdrive.
Turn on the head unit and it will boot with factory settings like a new device....
Note that there are also ROMs for flashing wit MTC flash tool downloadable.
But the versions for installing from USB sticks ( po russki - dla flashky) are more comfortable to install and I don't own a Windows pc. So this variant was my favorite method...
Regards and good luck...
Edit: if your unRAR program asks for a password for unpacking the RAR file, then use Eazy unRAR app from Playstore on your Android device - it ignores password lock in RAR file ...
Edit2: the 5th gray spoiler in the top header of the Russian forum hosts the links to the ROM RAR files...

The USB flash drive method didn't work for me, Device doesn't detect USB while booting up. I tried everything, connecting the test points, pushing reset button etc. to no avail.
SP flash tool does seem to work, I have tried uploading several available roms, only these three uploaded successfully,

but didn't turn on the device. Device turns on but I get a black (backlit) screen. What else is there to try?

No idea, what else you can try
If you can connect a PC to headunit and flashed a ROM with TWRP, may be you can use adb reboot recovery and clear data and cache via TWRP?
Hope you find a solution to boot your HU...

No luck with adb either.
seems like my only option is if I could get the exact ROM for this device and flash it. The seller was less than helpful, so Aliexpress refunded me in full.

Any ideas ???? my device is a brick at the moment, and doesn't recognise usb flash drive for updating.

Thanks for that, wow the memory dump is massive more than 4Gb! Did you use format and download or just download in the Flash tool? Do you know the files the scatter file took from the memory dump? So, you didn't use any files from the first download where you took the scatter file from? I'm still having a problem connecting to my PC may have to use the hardware forced (testpoint) method!

You need usb male to male cable, attach it to usb1 on the device. but not yet connect to pc. Run the sp flash tool. and select the correct scatter file. Then run which ever function you need. after that connect the usb cable to pc while connecting these two test points (picture) with a small piece of wire to each other. After it is recognised and operation starts, you can release the jumper wire.

Thanks, when I use the scatter file from the first download and put it with the files in the second download it only picks up the preloader file nothing else?

Hi, Scatter file is only needed to make sp flash tool recognise the partition table on the device. no need to download anything via scatter file. press Ctrl Alt V , then go to Window and select "write memory". Set start address to 0x00 Use this to write Boot_1 , Boot_2 and User, to EMMC_Boot_1, EMMC_Boot_2 and EMMC_User respectivly. thats it.
I hope it helps.

How to update the radio Alps full_8227L_demo

Hello, please help with updating and where to download new software for the above-mentioned radio. Chipset AC8227L, 1/16 GB. I downloaded programming from https://forum.xda-developers.com/t/help-with-this-chinese-hu-alps-8227l_demo.3930394/ ; every time ith throws an error to let me check the usb and files. I changed 3x USB stick and memory cards, each time the same, FAT32 format.

Hi, format SD card possibly greater than 4GB with standard settings - FAT32 or ExFAT file system and deafult allocation rate.
Next, download one of firmwares that suits your device (for 8227L it has a lot of them on this forum but your device maybe have different UI than XPH.8227_8_xxxxxx mentioned in this above link).
In my oppinion the ones that will work for your model begins with XRC,CHS, JC.
Firmware for download are like this example : CHS.8227L-8.UI4.Android_10_ver.6_xxxx(date of update)
After download and unzipping two files, .bin and .upd transfer those two files on freshly formated disk, nothing else just these two files. If transfering from PC or laptop make sure that you eject the drive before pulling out from PC.
Next step is to make the unit recognize system on SD card. Put the ignition key in contact mode or better turn engine on (before that insert SD card in memory card slot, not MAP slot !) and start tapping with one finger on center on screen untill message DETECTED is seen on upper screen area. If successful it will recognize files and start automatically updating (wait till finishes and enters system / UI), if not or fails to recognize files for update repeat process two or three times untill successful.
If still nothing, enter erase mode / recovery mode (purge of internal memory and files) by tapping with all five fingers on screen. When recovery is completed (it will turn to factory settings) device will be empty of all memory tasks, prevoius configurations etc. , just clean install of Android system, running and with no apps and settings configured. Then insert SD card and try update again.
If device even won't go in recovery mode then you have some factory settings like "protection" or "install" enabled. Turn this off both in factory settings / menu OTHER.
Good luck !

It's on forum here just type in search bar 8227L firmware and find best choice for you. If not found wil send you a link.

Sorry but I am not able to find the latest software compatible with my radio, there is too much of it, please help.
I will add that my radio does not have slots for SD cards and Maps, there is only a female USB input to which I can connect a USB flash drive, the device is fully touchable without buttons.
it is probably a Chinese counterfeit I bought on aliexpress, there will be a problem with the selection of the update

Similar firmware to yours is here https://drive.google.com/drive/folders/1a9yoWoiuMZRoQVL5O677Y9tmQHHAtmbo
Try to install this one it is TSKJ/CHS UI firmware for devices with 8227L chipset.
Extzract and put downloaded files onto USB drive formated for FAT 32 and try updateing.

memory formatted in FAT32, tried for two different, only two files extracted, each time in green DETECTED and after a while in red "Fail, please check USB and files", I tried several times

restoring the settings with a five-finger touch also did not work
I deleted the data to the initial state, but the update still does not start

I noticed that if I detach the USB and I make a finger movement during startup, the symptom is the same, as if I would not see the usb

Do you have install option in factory settings disabled ? Or protection option ? If do deactivate PROTECTION and enable INSTALL in factory settings (pin code) / OTHER submenu. Then try updating again.

yes, I have it done, I also entered the pin, unfortunately unchanged

Use another USB drive with 2.0 speed not 3.0 if this is the case.
Maybe it's just some stupid thing like this that is keeping you from updating.
If this not succesfull either check your device usb ports if they are working thru USB debug command in factory settings, also turn on all USB to be 2.0 and not 1.1 maybe will help somehow. I think that USB port is missconfigured and are causing not to update.
Another thing , if you have by hand any SD card and USB card reader try with that.

I have debugging turned on in the settings after entering the code 8888, and the USB is switched to 2.0, I tried with a new pendrive and with an SD card reader that I put into the USB, unfortunately still unchanged, I also changed the USB input on the back of the radio by switching the cable

Hm, this is a hard one, has this unit of yours been rooted ?

Honestly, I don't know how can I check it? how to root?
If it turns out I have root, does that change anything?

Install from Google play any app that contains root tester and see. Yes if it is rooted device is modified and altered and do not have stock firmwares, which leads to undesired complications and problems.

If the device turns out to be root, it is possible to work around it in some way to install other software?

I checked, the app showed that my device does not have root

today I bought memory 2.0, but still unchanged, these are my settings, is everything ok?
