And I have the same problem. There was a firmware 8227L_8军UI03-国11_v3_20220714. everything worked well and a few days ago there were problems with the head unit. the screen goes dark and nothing works. I turned off and turned on the device again, everything started working. I flashed the old firmware from the seller 8227L_8车易达UI01-国99.0_v4_20190829 everything works again. but as soon as I go to the play market and update Google services, the device slows down and freezes. an error appears (the application "Ts3561" does not respond) the Bluetooth icon flashes. I did a factory reset. The device has been working normally for 2 days. I updated Google services again and the problems started again.

bought from a seller on the net for 6 euros, but this too is blocked. The only thing it already has some new applications already installed but for android auto you need to buy it with a paid code
[Android Head-Units] Samvel72:
If you install the firmware and test it, please write to the forum are the problems gone or not
[Android Head-Units] freeman94:
exacly the same, just before the crash message with com.ui8 the bluetooth icon just dance on and off

What I think after reading post from you guys, is that in fact the culprit of the issue might be the google services update from playstore, as After restore factory and add google to device I update the playstore google apps

If the crash occure I might test it out with just leave the old stock version, or just uninstall update?

What more we could try, Bata update for google services?

When it comes to the firmware, its not that hasslefree as you might think of.

I speak with my seller, he gives me updates, but unfortunitly it will remove my Mercedes UI and override it with fancy colorfull one, with is no go for me as I like the clean merc UI

The 2nd thing is the Update process itself. There are informations that sometimes after update the resolution is ****ed up and you need to change it in 8888 setting, with is no possible as the screen is out of place and you need to connect external monitor, with the connector on back of the headunit, so you need to remove it from car, in with my car is whole dash :(

Keep it in mind guys
[Android Head-Units] freeman94:
@Anton TNT

When it comes to settings in 8888 i just put everything like u said, but before Bluetooth version (0-4) I have bluetooth option 1 / 2 with one to use, and

about ASYNC and SYNC,

is SYNC mandatory to set as with this option it controling my whole smartphone voice, and ASYNC is just better when it comes to usage of volume as its independent to radio, no phone involved.

UPDATE: Provided APK for Playstore can't be installed
[Android Head-Units] Samvel72:
I can't do it. just like you. I think more people will face this problem google
[Android Head-Units] JIm_stos:
@Anton TNT

Well its done, lets test it. But im ari

Hi @Anton TNT

I'm afraid it's not just a G-Apps thing.

Because in the past:

- Had resets on the radio and was never connected to the Wifi, so updates never happend and radio did resets.

- Also Tried force updates on Goodle Aps, and did susccesfull and then after some use... OFF/ON reset and wipe.

But there be always Hope :)

So followed your instructions and did all configurations.

Also had problems updating the APK to Playstore, but I tried thru Google Maps and forced updates, and did it in 6 APPs. Then restarted with 1414.

Tomorrow will stress radio and give you feed back.

Thank you so much for your precious help!!!!
[Android Head-Units] Samvel72:
Anton TNT was right. only on our device it is not possible to do according to the instructions. When the glitches started on the device and everything started to slow down, I went to the settings of Google Play Services /Storage, then CLEAR CACHE, then MANAGE SPACE and made CLEAR ALL DATA. and everything worked for me and Bluetooth and side buttons and glitches disappeared. but after a while, problems appeared again. Some kind of Google program prevents the device from working.
[Android Head-Units] JIm_stos:
@Samvel72

Reading your post, remembered my first problem with this radio, the glitches and the slowness.... and I solved it, it's the CAM connection!!!

Please go to SETUP using code 8888, go to CAN TYPE menu, take a picture of the actual setup just in case

and change the CAN CODE to ZERO.

Immediately your radio will go fast and furious.... then reboot using 1414.

Maybe if you have luck (i don't have that with mine), contact seller and ask for wright code of CAN, by the way, wich car you have radio installed? an Audi A3?
[Android Head-Units] Samvel72:
Yes, thanks for the hint, I looked at the CAN CODE and I had ZERO. But it's not the slowness of the device, but the failures in the operation of the device. I have a KIa Forte Koup SX car. I really don't know what the code for my car is
[Android Head-Units] Anton TNT:
Then use system settings like it is configured, one thing to say for playstore, Chinese merchants have their own version of Playstore that has nothing to do with Google playstore, it is forbidden for them to copy Google playstore so they replace working Google version for their tampered/pirate one. Whole system is becoming unstable with the actual Android system, especially after a while, let's say 2-3 years , because of a new version units are introduced and are selling well and older ones with dates arround 2018-2021 are obsolete and without support from dealers. Only thing to do and make it less obsolete and without glitches and errors is update apps somehow to the latest (not Chinese versions installed) like Google and it's services along woith other crucial apps in order to work with older units.

If your units do not apply pasted link I posted, find a replacement online and install something that will work for you.

"Google services" (all processes of Google and associations of apps with Google accounts) are known to be hard to update manually and when unit is online sometimes their "Google" version does not install services at all leaving system slow and unresponsive.

For a fact , it is true that some process, like main interface "com.main_UI_8" (interface of unit) crash after a while, simply by that when it versions fails to synchronize with current ones. then bad things happen and begins to occur.

System wants to update to latest but cannot, because of wrong versin, like Windows 7 or Vista cannot upgrade on PC to a better version beacuse it is simply to old to get WIndows 11, hence, it can't get any more updates.

Mostly, to do now , when all help fails is to update ROM and find most recent updates (firmware updates) later 2022 if exists. Like, for Junsun I think V3 version PRO is out but not for older units till 2020. Only for 2022 and later, so it 's risky to install it on older units.

I have removed my old 8227 unit from car last year and have bought a TS18 Topway with Qualcomm chipset and processors rather than Mediatek Chinese craaap , it is simply with too many bugs and practically with no support over time by sellers.

New units like TS10-TS18 have online update and support via 4G installed network on unit. No need to look for updates here online or find a correct bversion, it's all on seller/dealer servers now. They release new version after two months or so, you just upgrade to latest version and that's it!

I have strayed a little there now, back to basics...

Have you guys installed on your unit com.ts.main_UI8 process interface file not native to your unit ?

Please tell me because I have tested this kind of interface on older unit and was also faulty and full of bugs.

I'm talking about moded or extracted process interface file from other units and prpared to work with 8227 units.

This file com.ts.mainUI8 is similar like this in older pages of this thread... https://xdaforums.com/t/alps-ff5000...s-updates-and-solutions.4167669/post-86722247 or here https://xdaforums.com/t/alps-ff5000...s-updates-and-solutions.4167669/post-86750371

Thing thats upsetting me now that i rooted my unit os the BT connection as unit keeps losing BT connection with phone. But if problem might be related to Google play services cant we simply install an APP repository like apk Pure and upgrade PlayStore version and Google Play Store to last one and see if problem persists?
[Android Head-Units] Samvel72:
Anton TNT You are right about the Chinese Google play market. I installed the original firmware from the seller, but the Bluetooth turns off unsuccessfully and begins to slow down the device. I reset the device, turned off all Google services, installed my programs from other sources and the device works fine. Yes we need to look for a new firmware if it exists
[Android Head-Units] Anton TNT:
Yes you can try that, any of version not related to Chinese stuff installed is better for the system, only thing that is tricky is to install it on system that has default apps of Chinese. Some non branded and non rooted units are diffiucult to change as they are locked with pin codes from manufacturers and sellers.
[Android Head-Units] vacarta:
hey, by chance I did the same today: I have factory reset my headunit and disabled all the google services. then installed WEGO and HUR from apk on SD card.

I am going to install Aptoide and try to downlaod latest Apps from there in case. I don't need usually to connect to wifi except for traffic data.

if this approach does not work in the coming week and system will start crashing again, I will try to update the FW.

will let you know if this approach works in my 8227 unit.

Yes please let me know I will be waiting for news.

Asked Xtron support for new firmware. Lets see what they say
[Android Head-Units] Anton TNT:
What version currently for extrons do you have on your unit ? I have firmware available to download dating 26072021, if newer versions are found please give me/us a link to download here please, thanks.
[Android Head-Units] vacarta:
so, I know that it is only one day but here are some updates: I have today connected the WiFi and started to download the maps for WeGo. Google apps still disabled and no issue in connectivity. good. The system is quite responsive and BT is working fine with no disconnections.

upto now no issues with one exception: I have troubles to record the stations in the radio and keep the icons order that I want. Every time I switch off the car the system come back to the original setup and radio loses the stations. I have found some guidance in posts #827 " go to factory settings with pin 8888 - then go to other menu where setting MEMORY/LAST STATE OPTION IS ENABLE THAT OPTION - MUST BE ON...... " . I can find all the settings except this memory/last state option; apparently it is not present or maybe have another name in my unit.

another thing that I noticed, but I am not sure and I have to double check later is that if I keep SD cards out of the slot the system seems not going to original reset.

any idea?
[Android Head-Units] Samvel72:
Настройки радио заходим в сервисное меню 8888, далее Радио и ставим галочку Частота, затем сохраняем и перезагружаемся. и все должно быть сохранено для вас. Насчет сброса не знаю, всегда извлекаю сд карты

They say theres some new version available. Will let u guys now as soon i have it.
[Android Head-Units] Anton TNT:
Known bug - system sometimes writes in SD card or USB drives instead of internal memory

Delete all ANDROID folders if present on SD crds or USB drives attached to system.

Then set up system, stations , icons etc. without USB drives or SD cards attached in ports and restart with saving using pin 1414.

When on main screen repeat save and restart using pin 1414 untill unit saves settings in internal memory.

Then you can attach USB drives or SD cards again in system.
[Android Head-Units] Anton TNT:
Freq and SD level have nothing to do with internal memory and saving stations. FREQ is common setting with RDS ON to almost all units. FREQ means FM radio RDS system will search one or more frquency of one radio station and which have more strentgh in signal. SD level searches ones with noises and low signals, less sensitive ones.

Hey all!

I recently bought my first car and it has a XTRONS system built in. The software seems really slow, volume buttons on steering wheel seem to have delayed response on the software, loses BT connection a lot and does not remember radio station presets.

I've been looking for hours for firmware updates and e-mailing XTRONS is not helping either.

Any of you have an idea what i can do best to update the device?

HMI: TSKJ.D.Q.F.2.03.2020.03.06.13.30

MCU: TS907.190518(H)

BTV: BT.19.11.12.1200(C0:81:35:1B:75:32)

Model: 8227L

Android version: 10

Important note: As this is my first car i have 0 knowledge of car radios. So if theres any step-by-step guides available with what i should do that would be highly appreciated!

Thanks in advance!!
[Android Head-Units] DizXDA83:
If you read several posts behind u will see many complaints about this units and software issues. In any case look for this firmware version on Google or so 8227L_8乐佳UI03-国外11_v4_20220629 it should solve some problems but as u will also find theres some bluetooth connection issues with some firmware. Asked xtrons for firmware update they should reply soon.

Update is simple just unzip you will find 2 files put those on a USB drive and connect to one of USB ports. It should update and restart
[Android Head-Units] JeffreyVtn:

@Samvel72

U might be rights

Problem is with Google Play services

When bluetooth on/off switch dance and I wipe data and cache it fix bluetooth asap, but only temporiarly (2-3 unit reboots)

What i did is manual updated APK of Play services and wipe data/cache again

So far, 2 days and couple of unit reboots its working great, finger crossed its permanentny

What i recommend also, and did myself is, use Aurora Store to updated apps, not only does it update apps faster then Play store unit(2gb/32) but it detect even newer version apps like (Google, test speech,chrome)
[Android Head-Units] DizXDA83:
Yes read about aurora thing is also read that when using gmail account u can have your Google account banned for using it... But aptoid seems to work fine and also updates stuff. Better that apkpure thats full of advertise!
[Android Head-Units] freeman94:
Dont know about ban google

I use the "anonymous" guest mode, as one of key features of the Aurora Store is it can work without Google stuff, and interface is clean no ads
[Android Head-Units] DizXDA83:
also i like the update main ui file MainUI_8227L_1.1 from topic https://xdaforums.com/t/appswitcher...devices-incl-autostart.4593865/#post-88620949 it changes the look from interface and radio for a better look! Give it a try

I use custom made Mercedes UI, with fits the car.

I dont like fancy colourfull candy interfaces
[Android Head-Units] Samvel72:
I do not overload the device, my device is working stably. It is necessary to go to the engineering menu 8888 be sure to do a full reset of the device. Erase All Content. and without connecting to Wi-fi, install Google Play services, and Google Play Store, download and install the versions that I posted above.

Any update to crashing mainui?

Did all the ideas works for you, Fix crash

I did all types manual update app, factory reset like 20 times no matters what i did IT just freeses unit bluetooth etc

IT was fine 3 days and today get in car and every time freezes. Unit is usless at this pointy

Its so ****ed up as IT auto launch with car no way to keep IT off + IT freezes audio if its loud only way engine off

At this point my only idea is flash firmware new that i get from Seller

I AM scared IT break resolution but what to do
[Android Head-Units] vacarta:
hi, as I wrote exactly one week ago, I have done a factory reset and disabled all Google services. then installed what I needed manually (Here WeGo + offline maps , Google Maps + offline maps , Aptoide and also Car Launcher AG). all the apps downlaoded by Aptodie.

After one week my headunit is working fine. Actually it never worked so good!

In the past, even before the UI crashes and BT on/off, it was anyway slow but now, after disabling the all Google apps, it is really good.

BT is fine and also Google Maps works fine and faster than before. I could even download maps without login with my account.

I have also fixed the issue of the radio not saving the stations thanks to this forum.

I can confirm that Google apps was the problem, at least in units similar to mine.

Reflashing was my last option for me as well but, as the end, I think I will keep it as it is since it is fine for me.

for your reference these are the characteristics of my unit:

HMI: JC.D.Q.F.3.01.2021.05.21.08.30

MCU: TS907.190518(W)

hope this can help someone. many thanks to all the members in the forum that helped me to fix it.

[Android Head-Units] vacarta:
Hi, I have terminated and disabled google play services and the playstore. To be sure I have also deselected the option "automatic updates" in playstore app before disabling. I download from Aptoide via wifi. Everythin is working fine and fast even if 8227 is an old MCU.

thats intresting, I didn't test with google apps tottaly disabled, remove permission etc,

Hello Team

I have this Device 8227L, but as seen below , and sofar it is with with 8227L_8-UI04v1-10_v11_20200312 software

So far , the Bluetooth is crashing after I login to google services, but before that, I cna play up to 12 hours musing without any loss.

The guys from Eonon, are saying that it is a Hardware issue, but I think it is not, because it happens, when I login to google play services and after that the system starts to crash and the bluetooth it self also.

Please advice what update I can use for this device and from whee to dowload it.

I have read a lot of info and I feel lost. Thank
