This is firmware for Junsun devices, I have tried that and have problem with radio.app. UI looks good but radio app keeps hanging or freezes most of the time. Solution to radio problem is to install firmware all over again and all tweeks and settings with it, but I'm tired of setting all over again.

I have proposed to my seller that he provide me best and "updated to date" firmware for 8227 devices, waiting for resonse, will paste this download link here if downloaded.

[Android Head-Units] Fecoopelastrah:
I really like the themes! Maybe there's anything else
[Android Head-Units] Anton TNT:
Has this been tested on MTK 8227L various devices ?
[Android Head-Units] mohamed taher elbstani:
All the LAUNCHERS have been modified to work together and the change between them is done by the THEME APK and I tried it on my FF-5000 and there is no problem
[Android Head-Units] Anton TNT:
Firmware is software / system of a specific device and updating launcher or skin is entirely different thing. What do you need launchers or specific firmware upgrade for device ?
[Android Head-Units] Anton TNT:
Funny thing is that when I try to install themes by APK installer (ver. 1) system tells me installation is not successfull. When opened theme app it just lists one default theme. Must figure it out how to install other skins. It's some Google "third app installation" protection shhittttt.
[Android Head-Units] Anton TNT:
OK people looks like after a while Chinese resellers gave me new firmware update for 8227L chipset devices - ALPS, XTRONS, JUNSUN, HIZPO, some MEKEDE or KIRINAVI branded devices etc.

One can use this update and install , it will work but beware this is Android 11 and when installed all license.dat that you currently have in your devices will be overwritten by new one for ANdroid 11 - which means one thing - error "license not valid" or "not activated". If any of you experiences these errors find a valid license.dat on Russian 4PDA forum.

I'm actively searching how to install this new license on my device while having a good UI and better version of Android. Any help provided is more than welcome!

Testing is in progress.

Link for download will be available soon.

I managed to install themes but on every attempt to change skin app crushes. Must close app afer setting skin , then I must press HOME button in order to skin to apply. So it works somehow.

And with this new update provided for UI4 and with this skin changer people can get nicer interface and better android system. many thanks mohamed taher elbstani for that.
[Android Head-Units] DizXDA83:
Go any images for this? is system fluid for 2GB RAM device? can you provide licence.dat file? thanks!
[Android Head-Units] Anton TNT:
All is in this post. it's CHS based so pictures of UI are up MTK04 called.

Scroll to older pages you'll find license.dat files, as for Android 11 and fluidity I don't know yet, I'm testing, try it on your device and see.
[Android Head-Units] DizXDA83:
what does it mean CHS based? you could make a small video for example with new UI working.

as i said for my Xtron new firmware version is this 8227L_8乐佳UI03-国外10_v63_20210726

i can try and ask again for new version. Did you manage to get new page wilth firmware versions uploaded?
[Android Head-Units] tedmusic88:
Hello, I have installed the latest version. I have an icon with a camera. I can't remove it. Can you help me ? Thank you 🙂
[Android Head-Units] Anton TNT:
Deactivate in factory settings, menu icons
[Android Head-Units] Anton TNT:
CHS is main UI interface for specific device, like ALPS devices has CHS software/UI in it's firmware name (and is name of the design of interface), some junsun devices has JS (and different interface) in the name of firmware etc.

No need to install any further updates, just see post above of theme.apk install these and desired theme from MTK 04 to MTK 09 and configure settings. Prior to that you need to install updates. Install software with UI4 firmware that I posted above (two links - android 8.1 and android 11).

If you feel your extron firmware is good leave it and just install theme.apk (UI changer).

As for new page it is not yet finished it tqakes a long time since i'm making it alone.
[Android Head-Units] DizXDA83:
Ok gotta you. Another question any ideia how to improve WiFi speed on this unit? Got a WiFi mobile hotspot with 4g sim card. By WiFi connection i get speeds around 7,8 mbps... At 1st i thought it could be hotspot itself or carrier problem but If i connect my smartphone to same device i get much more speed witch leads me to believe its headunit itself. I have hotspot right next to unit so its not poor signal reception...
[Android Head-Units] Anton TNT:
I'm afraid this is Chinese quality you can't do anything about it. You can isolate wifi antenna on the back of device with some small rubber band or isolation tape for wires. It signiffically improves reception.

Problem with Chinese antennas is if not insulated and touching casing of device it can cause dissipation of signal.

Also take care of rest of antennas there like GPS and radio antenna inputs. You can also insulate those if they interfere with each other.
[Android Head-Units] DizXDA83:

Hi, yes you can use it on your device and other firmwares aswell as long it has 8227L_8 in firmware name.
[Android Head-Units] Anton TNT:
This apk and BMW theme crashes on ALPS F5000 device it is not designed to work with other than BMW interfaces.

On my device it loads all , but radio app and player.ts soon after startup crashes.

com.ts.UI8 process completely overides old version and it is hard to get back original one, unless you do complete reinstall of firmware again.
[Android Head-Units] Anton TNT:
If not found regularly try remove it thru canbus settings / click on specific design for your car and deactivate option that says ICON CAMERA or something like that.
[Android Head-Units] ccaparli:
which one is the most reliable for daily use? I ve chosen this one according to the previous posts.
[Android Head-Units] Anton TNT:
Difference is with interface you are using (UI in firmware name) and date of firmware (year). So, if you have android 10 for you are firmwares with UI 3 or 4 and with ver. 6 or 7 dated 2021
[Android Head-Units] Anton TNT:

I tried this com.tsmain you proposed and it works, nice UI from Junsun devices.

Can you tell me where have you found those ui-s, themes, launchers and com.tsmain.UI8?

Can you give me links to those things ?
[Android Head-Units] Anton TNT:
Also have a problem with radio that cannot resolve.

radio.app inside Android system freezes and can't do anything with it.

Best solution is to install firmware again and it works for one time until engine shutdown. At car ignition key contact and reboot of HU radio freezes again.
[Android Head-Units] mohamed taher elbstani:
I always keep an original copy of the firmware, and whenever I find a new upgrade copy on any site, I download it to my device and extract the programs from it using File Manager + 2.6.3 and after that I re-download my original copy because it contains the activated programs and maps, and after that I do an update using the extracted programs until I do not lose any activation of the programs and I share them with you so that everyone can benefit
[Android Head-Units] mohamed taher elbstani:
You may keep the factory default settings file on the USB flash drive or on the internal memory of the device. Whenever you restart the device, it reads it and this problem occurs and the solution Delete the file from the flash drive or internal memory After that, the device needs to be restarted at least twice to save the new settings
[Android Head-Units] Anton TNT:
I tried this many times deleting also android folder and others like TS etc.

I didn't know about these three files from pic 3, will find them and delete.

Also, have found a way to write settings to usb attached , in factory settings there is menu MP mode which allows to save all settings to desired card or USB drive. This is helpful against configurating all settings all the time when have to install firmware again. When installed just import all settings at MP mode/IMPORT.

As for "radio" and "other" menu, all settings are correctly set ! But not sure if radio will work again it seems that IC radio chip is malfunctioning. Now even after update of firmware, sometimes it won't start, just freezes. it takes a few updates untill radio works again. So my question is : what is causing radio app to block at start and freeze?
[Android Head-Units] mohamed taher elbstani:
Assuming that the problem is in softwaer, you will need to download the original firmware using SP_Flash_Tool, but you will lose all the activated applications such as Android Auto and Maps.

And in a previous post, I showed the specifications of my device. If it is compatible with your device, I can somehow send it to you
[Android Head-Units] Anton TNT:
Please do ! On email I'll write it to you in privateb chat , thanks.

[Android Head-Units] Anton TNT:
Good to know for rooting and getting to factory settings, but will not risk bricking device if not 100% sure in what I'm doing.

Still, I managed my radio.app to work with original firmware that seller sent and is working now and with this 3.com ts.mainUI8 that you sent it has a nicer UI and with themes posted above.

Will see how long it last operating. Now it is just matter of time when unit memory eventually, when new card is inserted in slot, will write again in wrong memory (SD CARD inserted - all files for iGO and maps and apk of APPS are there aswell). As for losing settings after bootup, that is history, in MP mode section of factory settings I have managed to save my unit settings (it's a kind a backup of unit settings) and now at every unit bootup there is no need to configure any icons again or setting each time.

I noticed also at factory settings that it can install "THEME icon" without installing third party apk , and it is located in ICONS menu. There you can activate/deactivate any icons showing in UI (like 360view, android auto, climate control, radio, DAB+ -if connected in multimedia, rearview camera, DVR, ATV etc.).

This "THEME" icon is mandatory for getting new themes from Ali express (found a bunch of themes for UI-s sold for small price), they are substitute for ugly UI's of Chinese firmwares. This themes look awesome and modern organized, but not sure if will work with various devices as 8227L mark is not in any description of this theme pack.

Coincidentally, I came across open source code for Head Units

(https://developer.android.com/training/cars/media), which means that as with Microsoft systems, the shell or the entire UI of the system can be changed.

As the Chinese do before the sale, we can also change the entire firmware to our liking and needs. RADIO app and TSPLAYER app (music with MP3) can be changed to change options such as naming stations, editing the entire interface for the radio, all the way to customizing the application and the new DAB + system. Will try this source code and edit, and test in BLUESTACKS platform (emulator of android system) on my PC.

[Android Head-Units] Anton TNT:
Launcher 11 looks very good and it is working more fluently with my ALPS FF5000, thanks for that!

Next one radio application issues , freezing ....

Radio application is working till 2 or 3 engine startups and engine shutdowns and then freeze.

So finally, I have manage to resolve this issue.

Problem is in two wires - "AUTO ANT" - antenna +12V (must be connected together two blue wires if you have those, one that goes from antenna or amplifier and other that comes from device harness cable), and another wire, the red one , that comes from amplifier (if you bought amplifier for FM antenna 3in1 - DAB+ and FM amplifier and connected it to regular radio antenna) and on this red one says it must be connected to 12V constant wire or + wire, ussually it has constant 12V volts from battery.

Now, with this wires connected correctly to each other radio app problem is gone. It works more efficiently with this 3.com.tsmainUI8 you gave me mohamed taher elbstani , thanks. Keep up the good work.

Also memory of device (last memory state, stations from radio, icons on main screen, navi set, etc.) is no longer problem as it has resolved by connecting wires correctly.

So I have the xtrons TSD700L from Amazon. It says it's the FF-5000 and it's 8227l-10. Is there a firmware for this? And will new firmware help the sound at all. My biggest issue with this is that it seriously lacks bass and I can't do anything to fix it.
[Android Head-Units] kolios13:
Hello, I have unit that has 8227L_11 in its firmware name. Would the firmwares posted in this thread work?

EDIT:

OK after reading a lot of posts I am little bit conffused as to what firmware would I be able to install. Maybe someone could create a table of the appropriate UI interface and device prefix (e.g. XRC or CHS)?

For example my unit has the following details:

About Device

HMI: XRCH.D.O.F.3.01.2021.07.05.09.30

MCU: TS907.190518(H)

MEDIA: HC_v2.0.0_210413_1030(v1.84)

BTV: BT.21.05.27.1500(C0:81:35:20:86:99)

Build ID: FF_8227L_11

I have asked the seller to send me an updated version and he sent me the 8227L_8乐旅UI05-国外11_v2_20220119 which as I have seen @Anton TNT you say it is slow? Would you be abe to say what my options would in terms of which firmware i could Install?
[Android Head-Units] Anton TNT:
Yes it will work but if it says in firmware name that is android 10 it will be android 10 not 11. Find a best match on forum here or on 4PDA for Android 11.

For your device most likely EXTRONS firmware will work perfectly (but it's Android 10 not 11), just like in mine, they are similar devices but I don't know for yours mine device is DSP 10 IPS with phisical buttons MTK ac8227L chipset based.

Extrons branded firmware has a lot updates of applications that stock firmwares do not have, including amplifiers corrections, AC climate control etc.

All stuff depends also what kind of canbus device unit have.

As for XRC firmwares , DO NOT INSTALL any of my firmwares that I posted if your device has UI XRC, there is specially configured firmware just for that units, I saw this firmwares a couple a days ago on this forum. Just search newest posts by criteria "XRC 8227L".

If you have older machine that has phisical buttons, and device infotainment recognized device as TSKJ.xxx.xxxx - CHS.8227L_8_UI3or4_Android 10 or 11 is firmware for your device , but as always, you must find firmware for Android 11 or ask your seller to give you one.

If you choose to install firmware with Android 10 on pre-installed stock firmware with Android 11, I don't know what result would be after update, maybe it will ask you to activate device again.
[Android Head-Units] Anton TNT:
Hi!

If you have DSP effects in factory settings (pin 8888 to enter) activate those by clicking on it and checking the box or set to value "1" and set AMP also to value "1"
[Android Head-Units] kolios13:
Thank you @Anton TNT for your reply. But I am a bit confused again. Would the EXTRONS firmware work or not in my device? I am sending you more details of the device I have:

SellerName: Uckazy
[Android Head-Units] Anton TNT:
It will but you said you have Android 11 and softwares are for Android 10, did you read any of content I wrote earlier?
[Android Head-Units] kolios13:
I am sorry @Anton TNT I did not intend to offend you. I would appreciate if you could help me clarify this out. I have understood from your wording that probably it is ok to install EXTRONS firmware (but it is Android 10). However you wrote afterwards "As for XRC firmwares , DO NOT INSTALL any of my firmwares that I posted if your device has UI XRC".

As I have posted my device has HMI: XRCH.D.O.F.3.01.2021.07.05.09.30.

Does this mean my device is XRC firmware and I should "DO NOT INSTALL any of my firmwares that I posted if your device has UI XRC"?
[Android Head-Units] Anton TNT:
Yes my firmwares posted are for TSKJ, JC and other UI's , do not install these but find XRCH firmwares on forum like it is said, search for xrch and 8227L criteria, and install those.

No offense is taken, it's ok!
[Android Head-Units] kolios13:
So I have installed the firmware the chinese seller provided me (8227L_8乐旅UI05-国外11_v2_20220119). Before installing the new firmware I have noticed that it is not Android 11 but Android 8.1 Oreo (as it is discussed again in this forum). I have updated the firmware, it is a little bit more fast but now I have other problems.

1. It says "Activation code does not much"

2. The volume up and volume down button in the wheel cannot be mapped.

In addition the HMI now has changed to: SHLL.D.O.F.3.05.2022.01.19.15.30(Error)

So my AMP is set to 1, but when I change over to DSP no audio comes through. I have all the DSP options but no sound.
[Android Head-Units] Anton TNT:
This is not your device firmware at all, you installed wrong update (and given to you by Chinese seller), find something to update on this forum, type in "XRCH 8227L XONRICH JUNSUN WITSON" and search or use this update to correct activation code:

[Android Head-Units] Anton TNT:
Does it play or do you hear something without DSP on ? If so deactivate DSP effects.

Also I reccomend to check your wires for sound/speakers (green/grey/white/purple - see or find wiring diagram - see if they are damaged in any way).

If still no sound update with new firmware - ask seller to provide you with newest update - latest are 2021-07.
[Android Head-Units] kolios13:
@Anton TNT I have installed the firmware you provided me but now the radio does not play. And now the device information shows:

[Android Head-Units] SkipReplay:
So that's how I'm turning the DSP on is by switching the audio IC from 3702 to DSP. Is there another DSP setting I must also change?
[Android Head-Units] Anton TNT:
Is it working ? There is no other setting not there I know of.
[Android Head-Units] SkipReplay:
No sound doesn't work. Sound works when it's set to 3702, as soon as I change it to DSP it doesn't work anymore.
[Android Head-Units] Anton TNT:
Then your car unit doesn't support DSP or is deactivated thru canbus device that controlls ECU.

One thing only I don't understand, why 3702? Is radio IC chip setting changed thru menu RADIO in factory settings ? What setting for RADIO CHIP is set in this menu RADIO? And what FM sense ?
[Android Head-Units] SkipReplay:
The IC type under RADIO is set to NX6686. there's 5 other options as well. FM sense is set to 18. My audio IC setting is under OTHER in the main menu.
