Seems to me that you might have yellow/red wire (radio memory) issue. Check wires for electric shorts and defection.

If issues with restart continue try this also...

At the back of unit: SWAP MEMORY WIRE AND ACC WIRE RED

Red wire ACC+ / KEY IGNITION must be connected to unit and canbus box - it starts unit and disconnects unit power by turning key / ignition mode / engine on / engine off

Yellow wire is constant 12V from car battery - it keeps unit's memory preventing to reset settings and saved stations of a radio.

Also, test your battery for issues - If car battery is not at 13.20 - 14.00V at full charge when engine is on then you have battery drain (and thus unit is constantly losing power and restarts).
[Android Head-Units] JIm_stos:
Hello @Anton TNT.

Still with radio resets and followed by data wipe. When I swap the wire (red and yellow) the radio does not turned on, so I put them in the same positions, it seems that everything was fine with the wires initially.

Battery at 14.25v with the car on and 13.7v with the car stopped But I still haven't found the trigger that does the resets.

I can't find any behavior to be able to reproduce the error....

Sometimes just turn off the car, or restart the radio to load the factory settings that may have changed for testing... or even change on Android developer some it does the wipe

I'm totally lost, tomorrow I'm going to do a battery of hardware tests with the software you recommended More and more discouraged....
[Android Head-Units] Anton TNT:
If still time , turn this unit for a refund or ask seller for replacement - It is most likely defective unit!

FLashing ROM of unit is only option now, but for doing it correctly I suggest you consult other pro members with knowledge of flashing roms and seeing other threads for flashing and bricking devices prior to proceed with this option. It may correct problem with device.

I would like to connect to this device thru some p2p program like teamviewer. It will require unit to be active and have active internet connection aswell as Teamviewer app to be installed on unit to connect to.

I have the following android car head unit. I am looking for firmware update. Can anyone help with hits?

And I have two problems with the device.

- One is that it forgets the radio stations when I stop the car.

- The other is that I can't seem to connect to it via ADB with a USB cable. It doesn't even show up as a device. Of course, in the 8888 menu, even if I enable USB debbugging, it is off again after saving and rebooting.

Maybe I should throw it out and look for something better?

Otherwise, if anyone has any suggestions, I'd welcome them. I am looking for a solution for a Mercedes Viano W639 2din.
[Android Head-Units] Anton TNT:
Hi, your device is with 8227L chipset, but wrong device and wrong thread for discussion , search threads about XRCH.x.x..x.x.x type of device that you have and it's firmwares. - UPDATE the latest one when found!

I can give you only couple of solutions since you wrote here...

Clear cache of device using app called file manager +, download it, then when installed, go to root directory and delete content in cache folder and all log files including factorysettings.ini file if exist anywhere on main root directory. Restart and then see behaviour of unit.

For ADB shell and USB communication use only USB cables version 1.1, not 2.0 or 3.0 and install correct adb drivers in order to connect to device.

For radio stations - when on pad to enter pin for factory or advanced mode, enter 1313 , resets radio app, and then use pin 1414 (prior to entering, set radio stations and close radio by closing it from memory window - clear all apps in memory) which is a normal system shutdown and save, rather than pin 4 which is MCU and unit hard reset.

After bootup, when unit goes into Android main desktop, go to FILE MANAGER + app and delete any residual radio app files if unit stores them on memory or USB drives - it will be files like memory.ini, factorysettings.ini, logs. It will require two times to get all this , save radio stations again and rebooting, and finally unit will save all data on main memory.

Also check on the back of unit if antenna of the radio is not properly attached to port and see if zero of that antenna cable , or grounding, is actually touching the case of unit, if not grounded radio will reset / freeze and not save stations.

Check for swapped cables (red and yellow wires on the back) also, yellow wire is constant 12V from battery (which also serves as memory of radio device/unit) and red wire is key ignition ACC/KEY (activates unit with key turn / engine on).

Try that first and hopes will help , report here is successfull.

"Good evening everyone. I have this unbranded unit for FIAT DOBLO' 2015. I updated everything with a file purchased on the net, but since then the whole screen has changed with new graphics, it crashes continuously and I can't connect to bluetooth it keeps detaching .

Could you kindly point me to an update posted later that restores my device? Thanks, I hope your help."

Buonasera a tutti. Possiedo questa unità senza marca per FIAT DOBLO' 2015. Ho aggiornato il tutto con un file acquistato in rete, ma da allora è cambiata tutta la schermata con una nuova grafica, si blocca di continuo e non riesco a collegarmi al bluetooth si distacca di continuo.

potreste indicarmi gentilmente un aggiornamento da poi postato che ripristini il mio apparato? Grazie spero in un vostro aiuto.

Thank you for your reply! Unfortunately I am completely blind on this subject. I can't find a thread that deals with the XRCH... firmware update. I also found this thread by searching for what the device claims about himself, that it is an Alps FF-5000. The USB cable is also an interesting question. I don't understand what depends on the cable if the computer I can connect it to only has USB 3.0? I will try to find a 1.1 cable from somewhere. And the driver is also a difficult question. How do I know what driver I need or where can I download it? If I can't find firmware, then a driver will be difficult.
[Android Head-Units] Mastef76:
Scusa, ma il mio modello è un 8227L FF-5000 !!!!

Perchè devo girare un altro thread

Read all in this thread , page by page, all about your device.

It is ALPS device but it has other UI for unit so will find you a best match as I said unit HMI has designation XRCH.x.x..x.x.x , usually download file would be zip file like 8227L_1_UI3_Android10.zip -> this file or firmware for download is based on XONRICH units. So search also "XONRICH firmware " threads also in this forum. There are lots of threads for viewing here and solutions.

BEST MATCH FOR YOUR VERSION of HMI is here - download and update thru USB drive or SD CARD - unzip two files in a zip file and put USB drive in port of unit and then start unit, it will autoupdate, then wait till it finishes:

https://xdaforums.com/t/android-12-android-radio-8227l-ui01.4524115/

For cables and drivers :

- find any old cables that has atleast 1.1. or 2.0 version

- drivers for conecting to a PC are here https://drive.google.com/drive/folders/1jhUOa_6DY_oCayNKJHWV_cvAZ6Kwf7NR

along with FLASH program, but...

!!! CONSULT WITH SOME PRO USERS that have much knowledge of flashing ROMs here on forum and read bricking /flashing ROM sections of forum before doing any of flashing !!!​

Thanks, I have downloaded all three files from your page 34 post and they work very well. the first is very fluid, the second has a few less pre-installed apps, the third of 2019 will download it tomorrow and try it thanks again.

I wanted to ask you again that Androidauto and Junsun Security ask me for activation credentials !!!

Do I need to install anything else for activation? Thanks again.

Greetings @Anton TNT

I'm happy to report that I managed to fix my head unit thanks to your posts...

The symptoms were a crashing com.ts.mainui8 - which would cause audio output to briefly stop and freeze the button input... Over and over again to a point of insanity.

It did inevitably require a reflash but I did find a much newer firmware (based on 11) that runs circles around the last one... so it's a win even though I have quite a bit of reprogramming to do.

For future note - I have a 16gb ROM / 2gb RAM model with buttons and knobs that is custom designed for the 3rd gen Toyota Prius as a direct replacement and the seller has dropped off the planet...

SO - this is the file I ended up using - which appears to be the latest dated firmware on this forum... the interface is great - even though I use my own launcher.

"8227L_8军灿UI03-国外11_v3_20220714.zip"

https://drive.google.com/file/d/1CPserhgePidz7Ee0FjAneczYTelgpq8W/view?usp=sharing (reuploaded here)

... also to note I previously I was running"8227L_8乐佳UI03-国外10_v63_20210726_extrons.rar" - and it appears "extrons" branded firmwares work properly with this unit.

I did have to go into the settings page using 8888 and set some settings and reboot a couple times to get things to stick - but I have a much better set up now thanks to you.

Thanks endlessly for your help - and let me get a donation link so I can support your support habit!

Cheers!
[Android Head-Units] Mastef76:
Ok grazie, proverò a scaricarlo. Anche per me lo spegnimento improvviso del com.ts.mainui8 con il blocco di bluetooth e radio.

Quali altre impostazioni hai modificato? Hai bisogno di qualche altra licenza di attivazione?

Mod translation:

Ok thanks, I will try to download it. Also for me the sudden shutdown of the com.ts.mainui8 with the blocking of bluetooth and radio.

What other settings have you changed? Need some other activation license?
[Android Head-Units] Mastef76:
Ok, thanks, it works perfectly, it doesn't crash.

Do you have android and Junsen passcodes?

I have updated my 8227l head unit with Janson v1 so there is a problem in youtube with me which I was facing before also the problem is that if I play something on youtube so video goes directly to full screen and then if I'm swiping up to see next video suggestions or I'm swiping down to mini video none of then are working I have updated youtube to latest update also but the problem is still the same. Can someone give me some suggestions for that
[Android Head-Units] Anton TNT:
I'm so glad that you managed to get it work, altough you still have problems with button knobs.

Sellers do not want to give this to users, but there is a file or files (in zip archive) to import settings for physical buttons and knobs on device using a factory settings IMPORT icon.

I have those for my Peugeot 308 but it might work for your model if it is similar to my old unit. It was ALPS FF5000 unit with 8227L chipset , if you want to import these files to set buttons and knobs go ahead (but files are AS IS provided with no testing or guarantee it wil work)

https://drive.google.com/drive/folders/1IdEQVWa4aRb2gLFXtbDKI_5Y5uX3E95o

These are not tested on different devices other than mine, so first before importing I suggest that you inspect your buttons or knobs if they are same and placement on unit is same. Look for similarities of knobs and buttons at the image of my ex unit at image below. Inside ZIP file there are .BIN files that with appropriate program can be edited and set for specific car model (placement of buttons and knobs of unit and connecting them to unit SWC using CANBUS etc.).

It is specific only for these units that uses old firmwares with name AC8227_8_Android 9-10_UI 1-4 from 2019 till 2022, including Extrons branded ones as they uses thir motherboards with DSP. Junsun firmware V1 , as we can tell from image, also works on these units.

I hope that you understand all written above :) if not you can contact thru email or PVM - private messaging.

Thanks and hopes up.
[Android Head-Units] monsieurtalbot:
Hey @Anton TNT actually the buttons and everything already works perfectly! I'm at 100%!!

Thank you for this follow up and I'll do some further research in case I run into another issue.
[Android Head-Units] Mastef76:
Ma per le credenziali di Junsen e Android auto non puoi gareggiare con niente? Nessuno li possiede?

Con l'accesso a Junsen, cosa cambia qualcosa? Grazie.
[Android Head-Units] devil9899:
can anyone help me with that
[Android Head-Units] Anton TNT:
Use Youtube aplication that came with firmware/software instead using it on chrome directly if this is the case. Or update Youtube app to the latest thru Google account
[Android Head-Units] devil9899:
I am using YouTube app directly from the play store and it is already up to date there is no any update left in it but still it is showing this issues I was facing the same problem in the before updates also and also before I updated my firmware to junsun it was the same like that sometimes it was working but then stop to work so from then it is like this now the swipe up or swipe down nothing is working
[Android Head-Units] Anton TNT:
I don't know, you should probably search for answers on net or youtube or google forums
[Android Head-Units] devil9899:
Ok so can you tell me from where i can get access to the accessibility shortcuts in jusun v1
[Android Head-Units] Anton TNT:
Use this : https://drive.google.com/drive/folders/1Uv5qe034wTpLRaY3PtRjcdvrHnP2naKC

V1 and V2 if you are sure its Junsun.

But I would first explore all threads containing 8227 chipsets and find a correct firmware for your unit.
[Android Head-Units] devil9899:
the thing is i updated it but now i have installed some apps which needs the accessibility permission so there in settings i dont find any accessibility shortcut there
[Android Head-Units] Mastef76:
But can't you do anything about Junsen's credentials and Android Auto? Doesn't anyone own them?

With access to Junsen, what changes something? Thank you. here's what it takes...
[Android Head-Units] Anton TNT:
Wrong firmware, you need a license to activate android UI, find it on Russian 4PDA forum
[Android Head-Units] Anton TNT:
car settings, google account , then approve all third party installs and check all options for permissions

Good evening,

I recently bought this headunit.

I wanted to know if there is a way to unlock the bluetooth to search and pair with nearby devices.

Android 10, 1/16 version.

Thank you
[Android Head-Units] Anton TNT:
Hi how do you mean unlock ? Bluetooth app is standard internal program in Android and must be unlocked by default and operational. Check for permissions in car settings / apps. If denied it will not work.
[Android Head-Units] gerocoo16:
Hi Anton,

Thank for you reply.

I will try to explain my problem better.I need to connect this headunit to my car's native bluetooth, as I can't connect it directly to the car's audio system because it is fiber optic.

But Native bluetooth and headunit fail to connect together because I can't "search" for nearby devices but only receive connection requests.

Is there a way to have this bluetooth function (as if it were a tablet or smartphone?)
[Android Head-Units] Anton TNT:
Use app in Android called CARBIT LAUNCHER or something like that.

here is a link -> https://play.google.com/store/apps/details?id=net.easyconn.carman.wws&hl=en_US&pli=1

Principal is same, connect from phone/tablet/other devices to multimedia or reverse.
[Android Head-Units] gerocoo16:
I will try,

Thank you so much!
[Android Head-Units] gerocoo16:
Hi Anton,

I still think my English is bad and I didn't explain myself well. This app allow to mirror my phone screen to the headunit but i just need to search with the headunit android A Bluetooth device and pair with this!
[Android Head-Units] Anton TNT:
Search similar software (bluetooth type) on Google playstore.

Must be some program that allows third party app to connect to your phone and reverse.

Android auto app has also such solutions.
[Android Head-Units] gerocoo16:
Thank for your reply.

I fixed it with an aux cable and hooked up the lighting as well.

I just have one last problem, the radio won't turn off if I remove the keys from the block! I connected both the red and yellow ACC wire to the native radio positive and the black to the groud.

What can I do?

Thank you very much
[Android Head-Units] Anton TNT:
Red wire is for ACC key ignition (car engine on unit is on, car off unit goes off) and yelloow wire is constant 12V memory from car battery, if this two are swapped unit will not turn off and drain battery fast.
[Android Head-Units] gerocoo16:
Let's clarify.

My car is a w219, Mercedes cls 320.

It has a native Bose sound system, in fiber optics.

Removing the original unit, I find the fiber optic and three brown/red-yellow/pink colored cables.

I think brown is ground, red-yellow is 12V and pink cable is lighting, Or am I wrong?

Thank you
[Android Head-Units] Anton TNT:
Yes but you could take some image of it and place it here, from where to where this wires goes and how it is connected to your head unit.
[Android Head-Units] gerocoo16:
The colors of the cables that reach the old radio are these, my car is also equipped with an external CD changer, placed under the radio, and here too I have these colors.

I don't have the exact picture of the connections, but I've created you a "legend" on how I connected everything.

Always thanks
[Android Head-Units] Anton TNT:
I THINK THAT WIRES WHICH GOES IN MULTIMEDIA - RED AND YELLOW - MUST BE DIVIDED. NOT ON SAME PORT/JACK IF UNIT HAD TO GO OFF BY KEY.

NEW MULTIMEDIA UNITS HAVE QUAD LOCK WIRES - ALL IN ONE HARNESS CABLE. (see on ali express)

IN THAT ONE - YELLOW GOES DIRECTLY IN YELLOW PORT OF MULTIMEDIA, AND RED ONE IN MULTIMEDIA RED PORT ACC AND CANBUS BOX, HENCE IT MUST BE DIVIDED IN ORDER TO WORK PROPERLY WITH DEVICE.
[Android Head-Units] gerocoo16:
Hi Anton,

Thank you for your answer.

I did some tests and I finally arrived at the solution!

I connected the red acc cable to the pink cable of the original connector and it works perfectly!

Thanks for all the help!

Hi @Anton TNT

Sorry for the delay in answering, was on vacation for a few days and then started a tour visiting some clients.

I used my private car on this tour, it was a good opportunity to do stress tests with more radio time!!! And I think I found a behavior that prevents data wipe and Android reinstall... or a way to force a wipe.

I always suspected that the radio didn't turn off properly...

That's why I tried to force a possible controlled shutdown: before turning the car off, I ran the code "1414"...then removed the car key. And the result was: 2 weeks without wipes!!!!

First time using code "4" on 2nd try....radio wiped again... Until today I still use the code "1414" and the radio is still ok.

So: it's a problem with a proper shutdown, I think your proposal for Flash Rom might be the way to go.

But first things first: the seller... is avoiding refund or replacing the drive... keeps sending out-of-date roms that do nothing and are just wasting time - I believe they want to rip me off.

@Anton TNT - want to try remote connection to the radio? With this update do you have any leads? -

I want to try a way to program some shortcut to make automatic code "1414" , I don't know how to make things more... normal.
[Android Head-Units] Anton TNT:
If radio is responding with code 1414 (shudown , system shudown) good and shuts down properly, then we will point to that as fix for the problem. Your seller can not give you replacement if 90 days warranty period is over. So refunds are also over. Your on your own to fix that.

I was hoping prior to connections lively thru Teamviewer or some other program, to check your default factory system settings. And please take photo of each menu inside how is set, then take photo of car setting / menu where system shudown in minutes is. Post here those images for me to see. And keep in one folder on PC as a backup if something will be changed in future.

After posting images will decide how to go further with this problem.

Flashing ROM image can be difficult enough for you at this time as requires proffessional treatment who has done this a few times and know those systems more.

Flashing ROM on your own can brick your device and original ROM system image will be gone.

This will be last resort.
