Hello! I have the same device on 8227 chip.

Thank you for sharing firmware.

My device work fine on his current firmware. I don't think about update, but i don't like only Equalizer. EQ app don't have settings Q factor.

Anybody know alternative EQ app for Junsun DSP ?
[Android Head-Units] sartee:
Hola

Esta actualización funciona para todos los modelos con procesador mt 8227L o solo para el modelo con 2gb de ram y 32gb de almacenamiento?
[Android Head-Units] RadianTOR:
I think it for only for 2x32 version with cpu 8227l. Because 4gb ram version is not same, and have little another hardware.
[Android Head-Units] vendo232:
hi @RadianTOR @Mad Mack

I have this radio from Junsun, it seems it is the same as you reffer 2x32GB 8227l could you please confirm it?

@Mad Mack thank you very much.

Quick Question: When I install the WebGuruTheme app I`m unable to find the stock Radio FM Tuner app available in stock launcher. Would you know if there is a workaround?
[Android Head-Units] Mad Mack:
On main screen,there is an icon to open FM Radio.

If you cant see it ,on the left side of screen is an icon to access other things like settings,app etc ,fiind FM radio icon in there too. Also WebGuruTheme app i dont use,i just use stock firmware ,so i cant comment on that particular app.
[Android Head-Units] vendo232:
@Mad Mack do you press RESET as in the video when you update? in the other link you sent it does not mention Reset.
[Android Head-Units] Mad Mack:
You can do it both ways. I always use the Video reset hole ,works fine for me
[Android Head-Units] RadianTOR:
Sorry for late answer.

I have the same device. And update device with the first firmware (UI01)

But later i think to try UI03 firmware too.
[Android Head-Units] vendo232:
hello @Mad Mack and @RadianTOR

I have updated my Junsun per your video above. All worked great. After installation I had to deactivate the Junsun Security app but after that all works great. The native radio app seems to be forgetting stations a lot, will have to look into it.

Also I was able to improve significantly my WIFI reception by plugging the Video rear camera cable, the cable has 2 blue wires, one is BT antenna and the other is Wifi antenna. Great results. thank you

Also, regarding Radio not keeping stations, after first install of firmware,reboot head unit,do an auto scan of stations,close radio apppp then reopen,the stations should stay
[Android Head-Units] Peaky00:
Hello to all, i purchase the Junsun PX9s 32G/2G 8core and got a couple of issues:

-settings memory is not kept (FM radio stations,..)

-the called touch study menu is not keeping settings memorised (i.e the left vertical touch buttons power, home, back, vol+/-)

I did reset settings factory no change, I contacted the seller and first told me to cross-connect some of the cables but nothing changed, then he sent me a link to download and reset the soft via USB but USB key seems neither not recognized when I launch reset from small top let hole screen.

Any idea to help?

[Android Head-Units] rodogg88:
I would suggest to reflash the firmware, see if that works.
[Android Head-Units] rodogg88:
Sharing is caring: I reached out to JunSun on AliExpress and got the latest firmware (July 14 2022) for the 8227L model.

Please check this link to download the firmware: https://drive.google.com/drive/folders/16aeW9AV-zS527-ReXgrwvPF44j0Z8lMW? usp=sharing

This is the video to update the firmware: https://drive.google.com/file/d/14gVw5UHWRCSTin1en7ROlk7Zu064Ivz7/view? usp=sharing

I already flashed it on on JUNSUN 8227L and it works fine, no issues so far.

Does this firmware has some application for Android Auto or Apple Car play, like i have speed play right now
[Android Head-Units] Mad Mack:
It has android Auto ,built into Firmware. I didn't use this as you have to buy an activation key. I just went to Google play and downloaded it from thereit worked fine
[Android Head-Units] carse:
Tried installing it, but after inserting USB nothing happened did i missed anything?
[Android Head-Units] Mad Mack:
Carse ,make sure its Fat32 or Large32 Format ,extract files to root directory.

Make sure Radio is off ,plug usb stick into usb lead from radio with ignition off. Turn ignition on to turn radio on ,immmediatley start rubbing the scrren with index finger ,left to right until you see the screen say "updating"
[Android Head-Units] carse:
Tried, There are 2 files in the zip one is 1+ GB other update file is 0 kb it's blank maybe because of that it's not working.. but try again maybe I missed something
[Android Head-Units] carse:
No something is not working for me, followed the complete installation process but it's not working

Below are the details.

MCU version: JCMM20-0-2022.01.06_14:58

System version: JCAC10003-0C2-V1.0.30R1-220708_1241-AA

Storage: 2 GB + 32 GB

Sound processor:TM2313

Bluetooth information: Bluetooth 4.1

ID:C1_CDA

why I want to upgrade because of below

its running on Android 8

, But it shows Android 11 in setting and on startup it shows Android 12, also speed play app that is used for Android auto is very unreliable many times it disconnect from wired connection to my phone then I need to reconnect sometimes the music stop playing and if i click on play it plays and stops again. Also the total software seems to be half backed as I can't change logo for cold boot or access Android system actual settings
[Android Head-Units] rodogg88:
maybe. make sure your radio can read the flash drive before you begin. then format it to fat32 and copy the 2 files directly from the folder to the root of the flash drive. then plug the USB into the car, start it up and restart the headunit. it should that the install on the restart. if the screen stays black, swipe it with your fingers for a couple of seconds.
[Android Head-Units] rodogg88:
where would i find that?
[Android Head-Units] rodogg88:
does your fm radio app still work? mine no longer works.
[Android Head-Units] Mad Mack:
Yes ,it works fine .You might have to Factory Reset or reflash .First ,try disabling that Junsun Secrurity. Goto app,then lookf for JUnsun Security ,then disable it ,reboot radio.

@rodogg88 fyi
[Android Head-Units] rodogg88:
flashed the firmware I shared a few times with no results. got an older one and flashed that one, edited the radio settings in the secret 8888 menu and then flashed the new firmware and that seemed to do the job. the FM radio is working again. Might also have something to do with the USB port. used the 4 pin port instead of the 6 pin.
[Android Head-Units] carse:
Where is this junsun security also my device doesn't accept 8888 there only one menu that i am able to access and that has 1234 as code
[Android Head-Units] Mad Mack:
Junsun Security app is in the apps section on the Radio on the latest Firmware.

Disable it ,reboot Radio.

Also ,please Specify what Junsun Head Unit you have ,post the specs here.

I suspect your trying or have Flashed to this Junsun Firmware that isnt for your device.

Please Check radio details ,post here .

carse, my headunit came in a box branded Junsun. its a Junsun 8227L. I think yours is a different brand but uses the same chipset so although its similar, it uses a different firmware.

I checked XDA and found this link but its download is a russian site:

AC822L link (https://xdaforums.com/t/ac8227l-android-head-unit-2gb-32gb.4487887/#post-87771145)

I just noticed that the maps that came with the radio is no longer installed and if I install it from the play store, i have to pay for the maps. iGO navigation.

Does anyone know how to restore it?
[Android Head-Units] Mad Mack:
You need to reinstall the software for the maps,the maps are there,but the software has gone. Goto apk manager on radio, look for the navigation app, thinks its igw or something. Install the app through the app manager,then walla, it should work again. The apk,s are saved through an upgrade ,you'll find them in apk manager.

Good Luck.

If anyone is interested in this, a few days ago I received firmware from Junsun, which, according to the consultant, is the latest. I installed them at home and everything is ok. There was a problem with Bluetooth but advice from Wotaisalive helped to solve it and everything works.

Hello,

I have a problem with my BT module in my MT8227L radio. I have installed the firmware from the link (2x).

My BT module keeps turning off and on. After restarting the radio, the BT module works normally for about 10 minutes until it turns off and on again. This then happens every second.

Does anyone know what I can do about this. Thanks...
[Android Head-Units] Mad Mack:
Solution for Bluetooth connection issue / failure.

After installation of a third party launcher app or upon updating the firmware it is a common problem that the bluetooth connection does not work (BT device is not visible and unable to discover another device). And also if you check the the MAC address of the BT device it will be value "Null"

With the following method you can activate the built in BT device :

First you need to go into the bluetooth settings and check if there is a username and password. (Important: you don’t need to enter anything yourself, the name and password must be assigned automatically.)

Then

Got to SETTINGS > CAR SETTINGS > EXTRA SETTINGS >> 123456 >> CONFIG INFO >>> tick the box, select >>> BC6 (in some version it is BS6) >>> disable all the others >>>> RESTART

Now it should work.
[Android Head-Units] dorkisbored:

In the previous post ;)
[Android Head-Units] i2c3e:
I'm sorry I didn't notice that. Unfortunately, even after this update, the climate control panel didn't stop randomly popping up all the time. Can't the problem be in the CanBus Decoder RZ 08 0027?
[Android Head-Units] i2c3e:
Now I found out an interesting thing. MCU says that there is CanBus decoder Raise - RZ 08 but actually there is RZ 58 which should be just for Passat B8. Maybe that's why the A/C panel keeps popping up and is there any way to modify the CanBus decoder type in the MCU?
[Android Head-Units] gduck:
Can you change the CanBus decoder type in the Factory menu?
[Android Head-Units] i2c3e:
I couldn't find that option anywhere. I can only select Canbus type where the show selects the manufacturer XP RCZ Hiworld etc. There I set the raise I select the car type Passat MQB and that's it. But I haven't found an option where I can directly set the CanBus model RZ 58 and that's probably why it's in the MCU menu RZ 08. Do you have any instructions on how to change this?

Thank you

Everything I read says it should be in the Phone app under Settings and then Calls. It is not. Searching the menu brings nothing up either. I have an old Pixel 2 on the same network.

[Google Pixel 5 Questions & Answers] draexo:
Stock, unrooted, originally AT&T, now TING (Verizon). Is there any reason to root a Pixel? (If there is, I will)
[Google Pixel 5 Questions & Answers] bobby janow:
That's an entirely different question with various threads debating the points. But to your OP it is also in the phone settings, calling accounts, <click> the account and Wifi calling can be enabled there. If it's not there then perhaps it's not available on your dialing network.
[Google Pixel 5 Questions & Answers] draexo:
The carrier (Ting/Verizon) turned it on. Magically, wifi calling appeared in my settings!

Now the Pixel 2 is using wifi calling fine. The Pixel 5 allows me to attempt to turn it on, but, alas, it fails. I contacted support again and they confirmed wifi calling is on for both devices. So, they did the "default" troubleshooting thing of asking me to do a factory reset on the Pixel 5 to see if that would make it use wifi calling.

I do not want to do a factory reset.
