Try a few times setting values and saving settings and restart using code 1414 on num pad (numpad where you enter fartory mode or type codes). 1414 means that unit will save and restart rather than just shutdown unit.

Could be a faulty antenna or gps antenna of radio that makes errors and lose settings, I had thos e problems, test also for this.

Find licence files to activate, you have also threads for licences. If not found revert old firmware as it was and try with new one suitable for youe device (by year and android version).
[Android Head-Units] Anton TNT:
First of all check your cable at the back if properly attached or damaged.

Also check if your other port USB 2 has charging abbility , if it is 5V port for charging and sharing data or is only usb port for data.

USB ports can be reset and reinstalled via factory settings also (pin 8888 or 123456 or new 8227 units).

[Android Head-Units] ccaparli:
I've shared same problem 1-2 pages before and posted my solution in post 1122. Extract the zip and put extracted file in a FAT32 formatted disk. enter service menu and type 9191. this erases old licence files and reboot. After reboot connect your hu to wifi and plug in the usb. When chinese text appear press the left button. If the licence file is suitable again a chinese popup came and "bla bla 40... bla" like message will appear. After that press a button and the hu will again resets. When restarted the activation error will be gone. (Again if the licence is ok for your hu, if not try to change the code inside the file and reapply the procedure. Another licence codes are shared ~10-15 pages ago)

Hello ANTON. Thanks for the info on how to proceed. I checked the connector on the main board from the back, everything is fine, nothing damaged, the connector is inserted correctly. USB1 works only when I connect the mobile phone, it starts charging and the charging light on the mobile phone lights up. Data transfer is only via USB2, mobile USB keys, SD cards, Auto android work there, and it also charges the mobile phone.

[Android Head-Units] Anton TNT:
When usb device was attached and usb icon appeared , did you confirmed and set USB for data transfer or just to perform as memory?

There on status bar when usb icons are , tap the usb icon and set it as data transfer, must be both usb1 and usb 2
[Android Head-Units] aginko:
When I connect a device to USB1, the icon does not appear and nothing happens, even when I connect the mobile phone it just starts charging but the icon does not appear. After connecting both USBs, only one icon is displayed, and when I disconnect USB2, the icon disappears.

go to factory settings in "other " menu , find usb debugging and activate it, when in the same menu find usb functions and enable all - usb =1 / on

Good morning everyone. I've lost hope. I tried to load all the firmware found and posted, but nothing! Some ask for the activation codes, for some the volume knob doesn't work and then above all after a few days the Bluetooth blocks and error 8. The steering wheel controls have never worked even when setting the 2015 Fiat Doblò car. We manage to find an updated one that works without errors and above all reads Android Auto? Thank you. This was the original one that didn't crash under any conditions.
[Android Head-Units] dedalos91:
A friendly advice to all, if your device is working fine stop looking for a firmware upgrade. It offers nothing, it's all the same. If you have a problem with the operation of Bluetooth or Google services then ok, there are updates for this
[Android Head-Units] Mastef76:
Yes, yes, because I haven't backed up the details of what I showed and now I don't know what to install to make it work correctly, thanks. Something functional super updated that works without errors and above all see the android auto phone

Anyone know how to fix bluetooth issues that freeze the unit and displays a 'com.ts.MainUI8 isn't responding' message? My unit works until I try to play audio via bluetooth. The song will play for about 10 seconds but then stops and freezes the unit.

Kernel Ver: 3.18.79

Build Number: full_8227L_demo-userbug 10...

Hi. I have usb debugging enabled in the settings. In the settings, USB1 - USB2 only have speed 2.0 or 1.1, but I don't know which should be activated. I don't have another option for USB to activate, I'm sending a photo.
[Android Head-Units] Anton TNT:
set usb A = 1, usb debug off , usb speed 2.0 , if still one of USB doesnt work try with 1.1
[Android Head-Units] Anton TNT:
NOTE : not for you only BUT ALL USERS !

First of all, if something works do not upgrade (only if you know what are you doing), second, you can test various firmwares on Android studio program (studio has option for virtual head unit testing live) on PC first and then try it on actual head unit.

As for firmware - FIRMWARE for this kind of devices ALPS 8227L - how many times do I have to paste the link for it?

USERS ! Follow and read all pages on this thread or on all threads containing firmwares and upgrades for 8227L units !

HERE IS A LINK TO FIRMWARE (AGAIN FOR 100th TIME)

(BASIC FIRMWARE CHS(for devices with HMI: JUNSUN-JC.xxx.xxx.xxx , ALPS TSKJ.xxxxx.xxxx.xxxx , XONRICH XRCH.xxxx.xxxx.xxxx , XTRONS KD or KV or TSKJ or TSK.xx.x.x..xxxx).Android 10-fake8.1GO with UI4 update year 2019 - I have also update for 2021 if anyone needs)

applicable only for ALL devices from year 2017-2022 with 8227L chipset , devices with button/knobs or touchscreen only

https://drive.google.com/file/d/1Ta2vL7Fc8tWmzmRxaJ-JMYGmlYYnRmud/view?usp=drive_link

Download , unzip , transfer two files on formatted FAT32 USB drive and install on unit (when unit starts it will recognize update automatically and install) !

Now, for FIAT DOBLO or any other model of car !

CANBUS BOX is included with many android multimedia units, so you must after installing update (after getting on first screen in Android) choose the right model for canbus settings (pin 8888 - factory settings) or steering wheeel and other car functions will not work. There are some occasions when sellers sent wrong CANBUS and does not cooperate with model of a car - REPLACE it or BUY a new one (on canbus box front or back area must be written text like hardware info and support for various models of a car - like if it PEUGEOT it will say fit for PEUGEOT 407, 308, 406 etc. - if your model of car and year is not on list do not buy it find correct one and buy and then set your model for canbus settings and car settings).

As for button knobs - you must import button configuration correctly thru factory settings / BUTTON menu in order for buttons / knobs to work. These files , if you or other users has not deleted original ROM still must be on your head unit disk somewhere or if you have contact with provider or seller just ask him for that files.

Download this zip file and see how these import files look like to find them and import them for correct installment of button / knobs - DO NOT INSTALL OR IMPORT THIS ONE ON LINK - everybody and every unit for various models of car has different button placement and config! https://drive.google.com/file/d/1Z8oJnaxya2ATl2WR7jKCcoMP4mzmyyVG/view?usp=drive_link

I hope that all users will read this and understand.

Happy solving and installing folks.
[Android Head-Units] Mastef76:
Good morning, thanks for the detailed explanations, now I'll tell you mine. I have already installed this update that you sent to my car radio but it doesn't work, it freezes, the car radio doesn't respond to physical commands and more. For the other updates you have shown, I have installed them all and tried some with some problems and they are all working until I connect to the internet and it runs the updates. From that moment on, after an hour or so it starts to freeze and the problem comes out with the bluetooth going crazy, everything freezes then it resets, in short, a problem. Can you figure out what this Google update is that ruins everything? Thank you
[Android Head-Units] Mastef76:
As you can see I have updated to the version of the link you showed. After I connected it to the internet it automatically updated the Google Play Store. It worked fine for a while and then the error came out! Is it possible that we can't understand what causes all this? 😭
[Android Head-Units] aginko:
Hi. I tried the settings you advised me but nothing changed, only USB2 still works. I will now try to install the old software from scratch. Another question, how do I get into recovery mode? Is there any instruction?
[Android Head-Units] Anton TNT:
Unfortunately google playstore (chinese version installed) is out of date and causing problems with some old 8227L devices, all "how to" is explained in older pages of this thread, so read about it, or just download Google playstore (Google original one from PC, not from your unit) and install it using USB drive (just click on that downloaded apk file and install). But before install of new playstore do the following:

- shut down internet / wifi connections from head unit

- go to car settings in apps menu and disable default installed Chinese version of google playstore

- then insall new one from USB drive and connect again, old playstore must be disabled or else it will deny installment of new version of playstore

- restart unit and see if everything works

I'm sorry for errors you guys are expiriencing but IT IS NOT MY FAULT, I gave you correct updates and BASIC firmwares for it , but they are over time losing support as new units arrive and have been sold by Chinese sellers, so this old ones are losing all support and connections with their servers, so... Sorry !

Best solution for now are to install a valid original version of Google playstore and it will update all Google services again, download this :

-> G. PLAYSTORE

to get rid of errros in interface. Or install different new updates from 2023 and if exist beyond this if you find one.

I have basic firmwares / updates only till October 2021.

I have seen also on this forum an update from 2023 but rather would not give my toughts and oppinions about it beacuse I have not tried it and not tested it as I now currently have new head unit installed in my car which is Qualcomm chipset and totally different than crrrrrapppy Mediatek Chinese chipset.

Regards and best wishes to all and hope you will solve your problems with units.
[Android Head-Units] Anton TNT:
Have you tried with factory reset, wipe data ? Erases disk and installs all things all over again.
[Android Head-Units] aginko:
Hi. Today I did a factory reset again and then installed the software via USB. Nothing has changed, USB 1 just charges and the icon doesn't even appear. When I look through the file manager, the connection shows only USB2. However, I noticed that after the factory settings and the installed software, the settings remained unchanged when I enter the settings in the menu - everything else is the same as before the installation, and the control settings on the steering wheel were not reset. That's why I asked if there was any way to get into the recovery menu, I also sent a photo. You can get there and use (wipe data/factory reset and wipe cache partition) on both mobile and tablet, then everything would be completely deleted. Now there is nothing left in the memory.
[Android Head-Units] Anton TNT:
I don't recommend wiping cache cause you'll have bigger problems. If you done already this consult with guys on forum / thread about device bricking and installing new ROM images.

I still think problem lies in USB cable that is not working well, you can try to buy new one from ali express and see if that works just check pin layout and connector to your unit of this USB cable before buying. And test pins with multimeter for voltages while connected to unit, if it gives out any volts.
[Android Head-Units] aginko:
I haven't tried clearing the cache yet, everything works, I'm just wondering if it would help anyway, thanks for the info.
[Android Head-Units] aginko:
Can you tell me where on Aliexpress I can order the USB connector separately?
[Android Head-Units] Mastef76:
Dear thank you, in the morning I will install the Google Play apk and update you.

Another question, how to apk android auto instead of easylink which asks for activation and doesn't work completely; what can I install? Always something working that does not require access codes and sees the Redmi 5g phone thanks.
[Android Head-Units] Mastef76:
Hi, I tried to install your link but it requires activation code! Do you know what it is? Thank you.
[Android Head-Units] Mastef76:
Hi, it doesn't download, it expired. could you send it again?
[Android Head-Units] Anton TNT:
I'm afarid you must take a look your own usb cable and see pinout / connector an order it, but similar are found here... https://www.aliexpress.com/item/100...sea!HR!2342727309!&curPageLogUid=R5r6kimnzHJn
[Android Head-Units] Anton TNT:
Try this one ... https://drive.google.com/file/d/1BGp32-YETJ2nNZDD_X3Nfw8aGWryim4M/view?usp=drive_link it is older version for 8227L chipset units, you can update it when installed, it's a 8.1 version. Leave it just like that if working fine with unit.
[Android Head-Units] Mastef76:
Good evening, update on the matter: I did the update tests as you described but nothing, once I connect everything to the internet the play store updates and the bluetooth is blocked. I've tried them all, even super updated JUNSEN, XTRONS etc. and nothing actually requires activation codes, especially JUNSUN!
[Android Head-Units] Anton TNT:
Did you DISABLED playstore or google services from APP menu of car settings first prior to installment of new one ?
[Android Head-Units] Mastef76:
Nothing to do, I deactivated the play store but not the play service, in fact after the installation the little triangle appears that there are problems with the play service. I installed Android Auto but it doesn't work and it doesn't see the phone! I have a redmi 10 5g. I'm trying them all but bluetooth always fails. Where am I doing wrong?
[Android Head-Units] Anton TNT:
... to clarify , when you disable Google services (Google playstore and other dependent Google services) all apps expirience errors/malfunctions in work environment. Solution is to take off any direct connection to internet , like wifi completely off till you install a new updated GOOGLE playstore (from PC or laptop while connected to unit), once you install this new playstore do not start wifi connection yet, restart unit and while in main Android desktop let procedure to finish install automatically (Google services or playstore will send status bar message on top that must update or are in updating mode). Then connect / turn on wifi, but do not connect to internet yet. Just wifi connections must be visible and ready to connect to.

Go to car settings / apps and there find all related Google services with Playstore aswell and deactivate them (DISABLE). If they have CLEAR DATA option , press it and delete old playstore data and other services data (with clear cache).

After deactivation of Chinese old playstore do not activate this app again. When disabled it will be off. Go to and operate with newly installed playstore (installed from PC and must be visible in all apps menu of android).

Restart again, thewn when on main screen again connect to internet and log in in playstore and do not let new Google playstore to update (take updating of apps off as soon you log in in playstore - menu / find apps updating choose disable and disable also playprotect). It should work.

The Bluetooth is constantly blocked, practically unusable! For Android Auto, once the app posted has been downloaded, the phone doesn't see it, while Easy Link does. It can't be the phone you say, some settings in the developer submenu to activate!

I need Bluetooth for speakerphone and it's essential!
