Hello!

I think the firmware is not related to the OS. You can try to update the MCU too with the attached file (Latest MCU for 8259) and accessing factory settings => update MCU => select .bin downloaded. But you still in the same Android version.
[Android Head-Units] rostamike:
Hello. I have a Junsun V1 Pro C 2GB+32GB model. My screen doesn't work after the latest update. I downloaded and installed the update through the head unit's settings. Boot logo comes on, for a moment I see that the "Tablet is starting..." but then the screen is black. Screen works when I try to touch it, and my phone recognizes the head unit through USB and Android Auto starts, I can play my music's phone on the head unit, but no screen. Please help
[Android Head-Units] ge.du303:
Hello,

I've just bought the Junsun V1 Pro.C mt8163 2+32GB (same as rostamike

photo above my post) and after updating it to the latest OTA firmware, I've lost access to factory menu settings. It simply doesnt want to type in the password to get into that menu(as seen in the video). I've also tried resetting it to factory settings, and nothing changes. I've tried contacting junsun via skype and email, but no one got back to me yet.

It says im currently running

MCU version CVD1810-WJ_22.10.24_399

Build number AJ_2023.09.25.10_3_2224

Has anyone else experienced this or know anything that could work?
[Android Head-Units] rostamike:
Build number AJ_2023.09.25.10_3_2224 this is the version I updated to and it practically bricked my device.....Junsun Support stopped replying...I hope you have more luck
[Android Head-Units] rostamike:
How did you reset to factory changes? Through settings? I want to enter recovery mode but I don't know how to
[Android Head-Units] PrinceLc:
We can't access recovery mode on the Junsun. The only head unit where you could go in recovery mode like smartphones was with PX6 Rockchip Prozessor.
[Android Head-Units] choldimir:
You have flashed the wrong firmware, you have an mtk8163 (Quadcore) chipset, it does not belong in this thread in my opinion. This thread is for mtk8259-mtk8257 (Octacore). It is normal that you have problems. V1 Pro.C is not V1 pro/V1 plus... You have to make sure what kernel the radio has before flashing!
[Android Head-Units] rostamike:
Good to know... Since there aren't any other Android head units for my car, only Junsun, should I upgrade to V1 Plus? Is it worth it? I have to buy a new Junsun anyway, but if it's more reliable and there's more support for it I'll buy a Plus instead.
[Android Head-Units] PrinceLc:
I have the plus with the 8259 soc and 4 Gig of ram but shown 5 gig in Aida64. It's good it's running on a Passat B7 AA works good and the unit has a good DSP
[Android Head-Units] rostamike:
Thanks for the info. Is 4GB RAM enough for you?
[Android Head-Units] PrinceLc:
Yes but more ram is better but 4 Gig is okay for the normal use of a car infotainment system. AA runs smoothly so yes

Hello, I just bought Junsun V1 PLUS 4+64GB, with UI 3.0 1280x720p.

I saw in menu that it is 825.

Which file should I take to update? Or just write messege to seller? But he need 5 stars for update, I think this is not honest
[Android Head-Units] choldimir:
You can update with firmwares at this threat. Last is v107 https://drive.google.com/file/d/1_yEwGWlVY-GP5RTLtV0LxPRwg9dg97-u/view

In my case the seller gave me another chipset...So, I recommend that you be careful even with the seller.
[Android Head-Units] Dudek89:
Is there any Way to check chipset? When I open system info there is 825x_pro.
[Android Head-Units] ziemniak120:
I bought Junsun V1 Pro for TT mk2 and i have problem. I cant Connect radio by Wireless Android Auto. It work only wired and i need to use cable. Do You know hot to solve that issue?
[Android Head-Units] ge.du303:
Yes, through settings, if you can't access it at all. Try getting into recovery mode(never tried myself). ive heard different methods of accessing it, not sure which one works e.g. press/hold RST button and touch the screen with five fingers, maybe tap multiple times after pushing the reset button.. or something similar.

Hope it helps and you're able to fix it somehow

Attached 8259P_军灿UI02v1280x720-国外_v107_20230919 to first post.

@spieva Tank you for sharing.
[Android Head-Units] choldimir:
Probably you have 8259. You can install an APP like CPU-Z for check chipset.

Update last firmware, latest versions for CarLetter are more stable. Pair the radio via bluetooth with your smartphone. Normally, the first time you have to connect by cable.

If all this doesn't work...Check that your Android Auto is updated in the Play Store. You can go into advanced Android Auto settings and try to see if you have the wireless connection active. Finally, verify that you are using a compatible smartphone. The wireless connection creates a network on the 5ghz Wi-Fi, I don't know if it works on the iPhone.
[Android Head-Units] ziemniak120:
Thanks. I check options and i thinh i have a 8259.

Can You explain me how to update firmware?

I tried connect wireless S22 Ultra and S23 Ultra and i cant... Wired connection works fine.
[Android Head-Units] choldimir:
Yes, you have 8259 update with firmware v107.

How to update the firmware:

Step 1: Download the firmware compression package and unzip the file;

Step 2: Format the USB disk in the computer as FAT32;

Step 3: Copy all files to the root directory of USB disk or SD card (8259.bin and 8259.upd);

Step 4: Insert the USB disk into the USB radio (preferably 6 pin USB)

Step 5: The car radio will automatically update the firmware, which is expected to take 5-10 minutes;
[Android Head-Units] ziemniak120:
Thank You very much!

I will try for 30 minutes and let You know.
[Android Head-Units] ziemniak120:
I updated fw but i still cant connect android auto wireless...
[Android Head-Units] choldimir:
Perhaps...you are using WIFI....off wi-fi to use AA wireless first.
[Android Head-Units] ziemniak120:
Works now. Thanks for Your help.

I just needed to configure bluetoothy by radio, not on my phone... 🤦
[Android Head-Units] choldimir:
Every time the firmware is updated, the bluetooth configuration, apps, etc. are lost. Don't worry, it's normal. I'm glad you got it, congratulations and have a good day!.

You can safely update with the v107 firmware discussed in this thread. https://drive.google.com/file/d/1_yEwGWlVY-GP5RTLtV0LxPRwg9dg97-u/view

[Android Head-Units] razvycodlea:

[Android Head-Units] choldimir:
I think it won't be lost, but I don't know for sure. Any configuration set later is lost and must be set again. Remember that if you update it is always under your responsibility.

I updated the firmware to 107 and MCU from TS-G5.201021(H) to SS-G5.230529 (H) , it seems to be a bit faster and more sensitive to the touch
[Android Head-Units] Dudek89:
My seller send me link to V94, I ask for V107, WHy didn’t send me that version.

PS. Where could I find new MCU? First update Firmware then MCU?
[Android Head-Units] marcanpaolo:
Good morning, Can I ask you for the link of the MCU SS-G5.230529?. Thank you
[Android Head-Units] choldimir:
Of course, remember that there is no obligation and it is not advisable to update if everything works well and as desired. There is always a risk of failure and bricking the device, especially with the MCU where we have so little information.

i can confirm that this firmware work with android hu from xonrich seller from aliexpress. my car is e61 from 2005 year. i onced got an update from seller it was this one(8259P_宝马UIiD8v1920x720-国外12_v9_20230316.zip) so i made a decision and installed that one from Bobec111/razvycodlea. i think xonrich unit is clone of junsun. cant find screens from cpu-z, below attached some info about my headunit.

but i got another problem, im wondering if i can update MCU from this post:

i want to update mcu because i got a problem when i turn off car for about 5-10 minutes the idrive knob doesnt work. if car is longer "not active" like about 20 minutes everything is working. so, what do you think would it be safe to update mcu? mine MCU is TsBMW.220511 that one is TS-G5.201021(VHD)

or @razvycodlea maybe u got an file with your MCU ? you got TsBMW.221126 mine is older.
[Android Head-Units] choldimir:
No, MCU are other files... no update if all work well

You can see this video =>

Ask the seller. It sounds like you have something BMW you could lose.

Well my seller started to ignoring me when i write about idrive problem :) typical for chinese sellers when there is a problem. If i know mcu is important to communicate with car, thats the reason i didnt flash it.. i didnt find any mcu file with tsbmw. to do some compare with SS-G5.2305291(VHD)

im wondering if SS-G5.230529 (H) in secret menu 8878 in can type has can type 176 BMW and there was three options to select when i enter 176 bmw old X1 and others. could someone please check it?

Hi guys! Can anyone help me? I updated the firmware to the latest version for BMW the 1920x720, I would like to use Carletter or Autolik but it tells me that you need an activation code.... Is it possible to find a version of Carletter already activated? Thank you very much
[Android Head-Units] pctjune:
Hello

I have a general question on softwares used on your Junsun HU :

1/ Firmware or so-called, like the latest v107 version

It seems it contains in fact the Operating System (Android 9 faked to Android 10 or 12), plus all the apps (GUI, Carletter, etc

Correct ?

2/ MCU

It seems there is recent update to release SS-G5.230529 (VHD). (I have TS-G5.201021 (VHD) on mine)

I guess this is a real firmware but on which part of the HU ? Is this more or less like BIOS on a PC Motherboard ?

3/ CAN Bus

We all have to select the brand and type of our car to activate the CAN Bus. I guess there is some firmware somewhere : is this stored in the CAN Bus itself ? if yes, can this be upated ? or is this part or the firmware of point 1 above and uploaded in the CAN Bus ?

Sometime I can see here CAN Bus version displayed on some screen shot from the "About Device", but it's not available on my Junsun V1 Pro running V51 firmware.

Mine is a Simplesoft RP5-RN-101 SW:V1.103.110BYPS DC:20230223

Hello everyone

I'm coming back to the topic after almost two years, this topic helped me fix my 8259 (when I bought one of the first versions without option to change the resolution of the original BMW menu). I would like to make a new update. The last one I installed was the 1920x720 version from this link, it looks just like in the photos, everything works very well (I can control the original BMW menu) but I have a poblem with Android Auto because it often turns off and the resolution is low, I have it connected via cable. Can I make a new update, e.g. V107 or V27? Will I still have access to the BMW menu after the new update? Is it better not to change anything and buy a box on Aliexpress to have a wireless Android car?

Hello, I have done a lot of research on the subject and I am unable to find the file or application that manages what each application volume corresponds to. I use radarbot, but the system recognizes it as a Bluetooth application, not as a navigation app, therefore When I have the radio on, it does not come in over the top, as if they do Waze or Google Maps, I did everything, I have the mainUI modified, I have tried to set the application as the default navigation, I have searched in /system/data... / system/app .... /data/data, I have given permissions to the app through OBD, I "rooted" with Shizuku through ADB, and I am looking at configuration files all over the radio, but nothing, obviously 8878 and so on I have also tried the codes, but I think that the MainUI app could have the key to solving the problem I have.

First of all, have you tried reflashing the older firmware? If you're able to, I would do that.

If you can't reflash it, I would suggest trying to use an app called Activity Launcher to enter directly onto the HU's factory settings. It's not the best solution, but at least it's a workaround.
