Working for xtrons clone 4/64 MTK 825x pro?
[Android Head-Units] Justenoughtobedangerous:
Just received update files for 6/128 MTK-8259 on a head unit for BMW E90. It contains 3 files, the largest being the system file with the other two being BMW specific for the Can Bus and MCU (iDrive functionality). The system file is dated Jan 8 2022. Google Drive Link to Files I have yet to install the updates but will post again once I do and let you know how it all went. In the link as well is the instructions for the system file update. If you happen to have a BMW with a CCC, CIC or NBT system follow the system update instructions first, then do the CAN update and finally the MCU update. Anyone else just use the system file and instructions. FYI I'm using a FAT 32 formatted thumb drive.
[Android Head-Units] Justenoughtobedangerous:
The system update went as planned, upon reboot everything is displayed in Chinese characters. I used my phone's camera and Google Lens to translate and found my way through the settings to change to English. For those of you with a BMW unit the Can update didn't go as instructed, "Upgrade file error" "Failed to update file!" message. I left it alone not turning it off and the file number began to change. Once it finished changing I rebooted the device, about 20 minutes. When I rebooted the device and checked the can it had changed from YX-BMW-GD-2 V206(L07.9097.NB80.1201,811) to YX-BMW-GD-2 V206(L07.B0F4 VB80.1201,001). I'm assuming this is correct even though the update didn't go as planned. I'm about to do the MCU update and found additional passwords to use that you might find of interest beyond the ones posted here like "8888" and "8878".

i have the same car, sould i update mcu aswell? btw do you have any pictures of the launcher?
[Android Head-Units] TorstenH:
The screen brightness gets controlled by MCU and Android only sends commands to the MCU to control the hardware.

You should install the Xtrons firmware too see if problem with display still perists or if your MCU is only partially compatible with the Junsun firmware.

It must be really hard to follow the forum rules. Don't be an egoist and write in English!
[Android Head-Units] Sogetsu Kazama:
Any chances to brick my device if I install Xtrons MCU?

I can always revert to my original MCU sent by the manufacturer right?

If I understand correctly the MCU will just send commands to car equipment but without any actual results if commands are wrongly coded?
[Android Head-Units] TorstenH:
You mean to flash a Junsun MCU on a Xtrons device?

There is the chance that the head unit will not boot anymore and you need microcontroller expertise to get it up again. :)

Best 1st step would be to flash the original firmware to validate if the backlight is working as usual again.
[Android Head-Units] Sogetsu Kazama:
That step I did but still same issue.

What is interesting is that the display will not lit at all if car was idle for more than an hour but if you start it and immediately go to reverse to activate rear camera it boots normally. If you restart the car (and the media) screen will work as expected. Sleep option is disabled.

It sounds like a software error but who knows, maybe it is the LCD itself. I will checke the input current to the display and check the video cable before doing more software experiments.
[Android Head-Units] 745pgil:
first of all thanks to all that have added to this thread espeacilly

TorstenH seems to me that you are the expert on these units​

i bought a NVGOTEV head unit about 1.5 years ago its a px6 4gb ram 64 rom worked great unitll recently i have been looking for a fix for a while now and came accross this thread

my destails are

HMI: ZHYC.G5.D.Q.F.xll.2021.09.29.17.30

MCU: is TS-G5.201021(VHD) i have seen some pictures with only a (H) how does that differ from my (VHD)?

About Car the build is

full_825x_pro-octa 10 PP1.180610.011 eng.root.20200426.093427 userdebug

Custom build version

andrios-trunk-p0.825X_PRO

Question: if i run (device info app info) it shows the build number as full_825X_PRO-Octa "9" PP1.180610.011 eng.root.20200426.093427 test-keys

why is it showing it different then under about car?

last but most important

this update 'Junsun V1 Pro v50 is it for my device?

if it is do i need to just update the latest version or do i need to go thru all of them up till v50

and would i need to back up the whole system first like i have seen some videos with spflash etc before i run the firmware update?
[Android Head-Units] TorstenH:
I have no idea because that's a secret of the Chinese manufacturers. I'm sure even the sellers don't know.

But don't flash MCU if you don't have an issue with it.

That's part of faking the displayed Android version. The Chinese want you to think you have Android 9. There are apps available which can tell you the truth (CPU-Z) and fake check tools.

You can flash it and because we're taking about full updates there is no need to flash previous versions first.

But please note: You will loose all apps installed by yourself and you will loose the pirated navi app installed by the Chinese, the voice recognition app with this white roboter.

You can create a backup but I don't see a need if you only flash v50. Don't use the newest USB stick - and maybe you have to try several USB pen drives to get the update running.

One additional note: don't store sensitive information (credit card) on the head unit. And use a separate Google account - not the main one you use on your phone.
[Android Head-Units] 745pgil:
i ran the update it was successful andriod auto works wreless etc these are the changes it changed the HMI,MEDIA,BTV but not the MCU and the build went to core 9 and ends with test-keys vs before the update it was core 10 userdebug(whatever that means)
[Android Head-Units] sharky172:
I set CANBUS type to 284.
[Android Head-Units] Pablo_2mm:
One thing I found out in v50 is when you're listening to music and tap the Google assistant button, the music does not pause automatically, also when you turn off your car the music continues playing in the smartphone.

Does anyone know how to fix this?

Anybody has the same issue? No 4G after sleep mode...

V1 Pro 4gb ram android 11 new firmware, if need for someone

It's NOT for Junsun V1 Pro with MTK8259/MTK8257 CPU!!! ​

Don't risk a bootloop!
[Android Head-Units] maxpan:
sajnos nem tudom, de mivel nincs ilyen fórum (V1 Pro 4 gb ram android 11) és most sokan ezt veszik, mert a Junsunnál ez az új. szóval ha valaki keres, itt lesz. mint én tettem.

Mod translation: unfortunately I don't know, but since there is no such forum (V1 Pro 4 gb ram android 11) and now many people buy this because it is the new one at Junsun. so if anyone is looking for it, it will be here. as I did.
[Android Head-Units] TorstenH:
Don't share fw here which is not for MTK8257 because flashing the wrong firmware will prevent the head unit from boot! A bootloop can be complex to fix! Please remove the link from your post and try to find the fitting thread for it - don't be lazy just posting it anywhere.

And it's never ever Android 11. The Chinese friends are faking the displayed Android version.

I still new and try to learn how to update firmware for my car HU. May i know if my HU which as per attach did compatible eith this junsun V1 or if not compatible can you advice which version can i use.

The reason i want to update the MCU or firmware because i did foresee my car HU had problem with sound system since after a while use it, the sound system didn’t work and no sound come from the car HU until i dismantle or disconnect power wire and reconnect it. Can you guys advice also on this problem? What is possible root cause and way to rectify it.. really hope if anyone can advice

Hello good, first of all a greeting to all and sorry for the English, I am with a translator. My question is how do I know which firmware is the right one for the radio I bought ( Junsun V1 pro 6gb 128gb ), where do I have to look on the radio?
[Android Head-Units] TorstenH:
Install application CPU-Z and check which CPU your device has.

Additional important information is MCU.

You should also ask your seller for latest firmware because name of the update file helps, too. And maybe you will get a link to a firmware which is newer than the versions here on XDA.

Is a SWC button customization even with connected can box possible?
[Android Head-Units] dansblackcat:
I completely understand.

I never actually ran that firmware. I found this thread before installing it and ran with the December update.

I think I might give it a go though, just out of pure curiousity. The firmware that came with the unit was pretty average.

I've seen the SWC screen but never tried to make any changes. Not even really sure how to go about it?

I have CAN BUS so can give it a go if you have some tips on what needs doing?
[Android Head-Units] TorstenH:
The Junsun firmware doesn't allow to remap the SWC buttons if can box is used. That's a pain for many users.

Choose CAN type, then click on All, you will find your car model associated with a number. After this check it and it will require reboot.

Each time you select it will require reboot…if it is chosen correct you will hear you car radio station in all your radio system.. hope you understood

Here are some pictures of unit

In description from seller is

10.25”

MTK 8259

1024x480

But i dont think it is true what seller says on their Page

See here
[Android Head-Units] TorstenH:
Basically your head unit is a Mtk825X unit and this would be the right thread.

BUT: But your head unit has a special (smaller) display height and a special MCU for BMW. Maybe your firmware supports special BMW features. You should be really careful flashing any firmware. You may loose canbus related features or end up with a screen not showing the full content.

Your first target should be to get the firmware file to have a backup in case of problems or to rescue the unit if you flashed the wrong firmware.

You could try to get in contact with the 'Junsun France Official Store'. Like all other Junsun sellers they wasn't able to answer my questions but they asked me not for my order number. Give it a try and send them the first two pictures and mention that you bought the head unit for BMW xyz...

I installed the XTRONS firmware again. SWC are not customisable with CANBUS. Bummer.

There's also no wireless Android Auto. So I installed the Autolink app from the latest Junsun firmware. It installed and launched fine but would only work with a wired connection.

I pretty much went straight back to the December firmware.
[Android Head-Units] bo4man:
Hello guys,

I have BMW E83 with Android 11.

The main problem is that the navigation turns on by itself?!

The only way to turn it off is by removing the battery terminal

I sent a video clip to my seller who sent me a version of the firmware: 8259P_宝马UI02v1920x720-国外_v73_20221110

For two weeks the navigation worked fine, now it started on again by itself.

My question is this a software issue or a hardware issue?

Does anyone have a newer firmware that they can send me?
[Android Head-Units] TorstenH:
The head unit turn on as soon it gets 12V+ on the ACC pin. I expect you're using a canbus box which provides the ACC signal to the head unit.

Maybe the can box misinterprets a can signal and turns on its ACC output.

You could check if the OEM radio connector of your car has an ACC pin and use this to turn on the radio.
[Android Head-Units] bo4man:
Thanks for fast answer.

No, I'm not using a canbus box. The strangest thing is that after the update everything was working as expected for about 2 weeks Going down to the car this morning I found the navigation working again... the strangest thing is where does it draw power to power itself when the car is off?
[Android Head-Units] TorstenH:
The head unit is connected to B+, too. This provides power to the head unit even when ignition is off. This is required to give the head unit the chance to shut down or stay in sleep mode.

Is sleep mode activated in your head units settings?
[Android Head-Units] bo4man:
The seller told me it was a software issue. Send me this version: 8259P_宝马UI02v1920x720-国外_v77_20230129

Resets the unit once, after disabling it, or resets the unit constantly (like all the problems with the HU not keeping settings) ?

Only once. No need to be worried. And the reset could also be caused by another action from my side. 😁
[Android Head-Units] ciorapel:
I can't be worried about resetting settings, because I have that problem right now :ROFLMAO:. I thought that I had a tip about the reason my HU resets (of course I disabled stupid Security and voice assistant ASAP as I installed the HU, and maybe that was the problem).

But it seems that I have to install this FW myself to test the ****** reset bug.

Did you saw any change on the FW ?
[Android Head-Units] TorstenH:
We're talking about different things. My reset was a reset on Android level including apps and data - have no trouble with factory settings.
