This is Ossuret software, just for you. Turn ignition off, wait 10 minutes. Turn on the ignition, hold down the reset, touch the display with five fingers. I hope you have another recovery procedure, you'll have to look for it. Disks are ok, don't use any program. do it in windows, fat32 must be usb format, it should start
[Android Head-Units] robfox1975:
I will give it a try, thank you so much I will re format the drive in windows but I have tried ossuret version 36 firmware and did not work, but all I can do is try....It has been suggested in another thread that my bootloader is corrupted and this is causing the firmware not to be recognised on the usb
[Android Head-Units] wybitny2:
It's not broken, it's incompatible, and that's why.

Good luck
[Android Head-Units] robfox1975:
Thank you I will try it and report back I am currently formatting my usb but not using quick format, doing a full format see if it makes any difference but i have tried the firmware sent by original seller from when i first bought it and that did not work
[Android Head-Units] wybitny2:
Vendors don't always ship the correct software, so there may be a problem. You always need to verify. I also did a number once, but it worked. As everything goes, I don't test something new, although I can't stop and I always come up with something, then I have
[Android Head-Units] robfox1975:
Well i hope it works, but even if it does not I thank you so much for your help
[Android Head-Units] wybitny2:
If you uploaded incorrect software you have a black screen, you have to do what I wrote, you have to wait a longer time, lock the vehicle, wait 10 minutes, it will not always jump quickly. You must be patient
[Android Head-Units] robfox1975:
I have boot logo ok, tapping screen gives detected then it goes to black screen with fastboot mode....It has been 3 hours since radio was last switched on so should be ok to try again
[Android Head-Units] wybitny2:
look again, it may also be that it's still not good software
[Android Head-Units] robfox1975:
I will be trying again with your software

I have formatted a 16gb flash drive to fat 32 using windows 11 and selected default allocation size, did full format not quick and coppied the bin and upd files to the root

So i put key in turn to on then press reset and five finger tap on screen?
[Android Head-Units] wybitny2:
You have to hold reset and press with five fingers.
[Android Head-Units] robfox1975:
Ahh now this could be where i was going wrong...1 last question do i hold reset before i turn ignition on?
[Android Head-Units] wybitny2:
Yes, hold the reset before turning on the ignition, you don't have to look to see if you hit the button correctly. It is best to see these two ways before turning on the ignition and during. Because I don't remember exactly, it was too fast, I was afraid if it would work. if the software is correct and the procedure must succeed, there is no way out
[Android Head-Units] gduck:
Yes, I will make a test version ;)
[Android Head-Units] Akaash91:
how do you get maps part working? mine doesn't show up
[Android Head-Units] gduck:
You can change default Navigation (on another, e.g. video player, etc.) software in the Settings/Car Infotaintment/Navigation menu.

In the main screen just TAP the picture in the window and than Navigation app will start in the window. ;)
[Android Head-Units] Akaash91:
the navigation app starts full screen when i tap on the picture and when i press the home button it doesn't go off. Any idea why that happens?
[Android Head-Units] gduck:
Are you also installed my PIP fix?
[Android Head-Units] Akaash91:
yeah so you install the pip fix first then the other launcher?
[Android Head-Units] Akaash91:
i tried the original launcher and that does the same. i think it might be my device im using the 887Q v10 firmware
[Android Head-Units] gduck:
Yes, it only works then, otherwise there are errors like you wrote.
[Android Head-Units] gduck:
I modified the 2. Launcher (black). Try it if you want.

NOTE: If you choose another theme with the topic switching app, it will be overwritten. If you want to choose it again, you have to install it again.
[Android Head-Units] Akaash91:
Okay i'll try it again so install pip fix first then install the modded launcher then it should work
[Android Head-Units] gduck:
Yes, correct! ;)
[Android Head-Units] kop4e:
Hi gduck. Can you mod MainUI_8667Q_v10_carmodel_v1_57_DoorOpen_and_PIP_Fix and remove rainbow road ?
[Android Head-Units] gduck:
The rainbow road is not in MAINUI. It's in the launcher ;) You can also install it the previously published on v10!

Hello everyone,

I have the firmware 8667Q军灿UI03-车模-1280x720_v5_20240113 X=1280Y=720 on my V1 Plus 6GB+128GB car radio

But I have a problem with PhoneLink (Carletter). When I get into my car, PhoneLink automatically connects to my iPhone, which is normal.

However, sometimes when I am on the Android interface, the CarPlay menu suddenly appears for no reason. How can I fix this problem, please?

Another question. In the default applications, for "Assistance Application" when I choose "Google" I can use the voice command "Ok Google" but every time I restart my car, the choice "Google" resets to "None". Do you have this problem? Is it a restriction of Junsun?
[Android Head-Units] fwpasx:
Today I received a new firmware from Junsun, 8667Q军灿UI02-国外-1280x720_v56_20240521.zip, not sure if anything is different haven't installed it yet.
[Android Head-Units] Rradistt:
It’s easy and simple to pick up a brick via cmd fastboot, flash system.img img files can be unpacked from the archive of any firmware via 7zip
[Android Head-Units] GregPete2001:
Hi, do you know how to change the letter size? Or the size of the display?
[Android Head-Units] kop4e:
This firmware 8667Q军灿UI02-国外-1280x720_v56_20240521.zip is stock for Junsun or other brand with 8667q chip?
[Android Head-Units] gduck:
Yes, Junsun. Interface is same the older (v53, v48, etc.)
[Android Head-Units] draklane77:
Hello. Can this firmware be installed in place of version 8667Q军灿UI03-车模-1280x720_v5_20240113 X=1280Y=720 ?
[Android Head-Units] gduck:
Yes. The visual difference only the Launcher. No rainbow road and no 3D car.
[Android Head-Units] fwpasx:
Stock, reiceved from official Junsun support.
[Android Head-Units] draklane77:
Thanks for your reply. I also saw another version on the forum.

[Firmware] Junsun V1 8667Q - 8G/128G VHD QLED

Hi, my seller send me new FW for my Junsun. IMPORTANT! This is for 8667Q chip. https://drive.google.com/file/d/1g1Uz--3FSbfCHoD2jEKHIHxFdW0S-R37/view?spm=a2g0s.imconversation.0.0.761e3e5fKk3Vqp I was make upgrade but not fully tested...

xdaforums.com

Can I switch from:

-> My current version: 8667Q军灿UI03-车模-1280x720_v5_20240113

-> Next targeted update: 8667Q军灿UI03-车模--1280x720_v10_20240626

- Are there any new bugs compared to the previous version?

- Does this new version support the fan? (I have the version with the fan)

- I have the 360° function with the 3D car on the home screen; am I at risk of losing it?

- If I mix up the USB ports between 4pin and 6pin, will it be problematic for the update?
[Android Head-Units] gduck:
Yes, this is a 8667Q军灿UI03-车模 update ( 360° function with the 3D car ), the latest public version. Yes, FAN support is enabled. I'm using without any problems.
[Android Head-Units] draklane77:
Thank you for taking the time to respond to me. Regarding the update procedure, I placed the two USB cables in my glove box but I don't know which one is connected to the 4 pin or the 6 pin. Can the update fail if I use the wrong USB cable to connect my USB drive?
[Android Head-Units] gduck:
1. your should extract to a FAT32 formatted USB drive: 8667.bin and 8667.upd

2. Put USB drive to the head unit (I think, in this case both USB port is usable). Update will start automatically. If the update still doesn't start, try with an another USB drive!

The screen rotates during the update, DON'T be scared, be patient! Make sure there is a constant power supply during the update!

PS: "an the update fail if I use the wrong USB cable to connect my USB drive?" NO! ;)
[Android Head-Units] yakdtai555:
What improvements are made?
[Android Head-Units] gduck:
That is never published. Usually the CANBUS communication part is updated. The Carletter usually updated, but last version still december 2023.
[Android Head-Units] ashrafegypt:
Thanks gduck

You safe my head unit it's run normal now
[Android Head-Units] yakdtai555:
Thanks @gduck for the prompt reply.

i guess u open v56 and check? So carletter on v56 is still "CarLetter 7.8.3.20231216 sdk 3.5.2_1124"?
[Android Head-Units] gduck:
Yes, correct. Still no newer version.
[Android Head-Units] ashrafegypt:
I need method for backup my head that you used for extract firmware
[Android Head-Units] draklane77:
Ahaha thank you. You are more competent than Junsun customer service!

I have a question about the quality of Junsun car radios. Are they really reliable in terms of safety? In case of short circuits, etc., do you think the protections (especially with the fuse) are effective?
[Android Head-Units] vinriver:
Hi

Greetings

If you are so kind and can help me. I have a Junsun v1 Pro 6+128 GB radio and I want to know what firmware I should use and the steps to follow to update it.

Thank you for any help you can give me.
[Android Head-Units] Rradistt:
Congratulations on your purchase of the radio. If everything works fine for you, then you don't need firmware.
[Android Head-Units] gduck:
You can check the actual firmware version with code 160 in the Settings/Car Infotaintment/About device menu.

About update method: you really only need to read back very little ;)
[Android Head-Units] JPxxxCol91:
Hi everyone.

Does anyone have the latest firmware for this device?

The link in the previous post has expired so if you could post a new one I would be grateful.

Thanks.
[Android Head-Units] vinriver:
Thank you for your time. My Junsun v1 Pro 6+128 GB radio, not all of its functions can be seen on the screen, in other words they do not work. My car is a 2011 Ford f-150 . When I open the doors, the image is not visible on the screen and I cannot control the air conditioning on the screen. The radio, BT, telephone and others work.
[Android Head-Units] robfox1975:
Thank you i will try now, hopefully it works
[Android Head-Units] wybitny2:
I wish you well, but don't thank me so as not to jinx it
[Android Head-Units] robfox1975:
It did not work....just touching the screen with 5 fingers did not even bring up detected, i turned off locked up and waited 10 mins....Gotback in pushed and held reset, put key in ignition and turned on then began tapping screen with 5 fingers rather than just touch.....i did get "to recovery now" come up but then all that happened was got erasing then reboot back to logo quickly tapped screen and got detected but then straight back to fastboot mode screen...I guess its fully bricked
[Android Head-Units] wybitny2:
you tried Junsun software, try any software. I believe that is not correct. What I told you about fingers doesn't always work on every radio. it should detect software on usb, it may also mean that you have a different procedure, I was looking for it on yt, on xda. there was a bit of searching
[Android Head-Units] robfox1975:
Yes I have been searching I found nothing on youtube I found this on here but it did not work(it was for a different processor but as it was junsun I thought it might work but it didn't) https://xdaforums.com/t/junsun-v1-2...mcu-t3-l-not-pro-no-4g.4519201/#post-87735333 I hoped it might work as most chinese units are very much the same.

I guess all I can do now is wait to hear back from the seller, it has a 12 month warranty so it could be sent back for replacement. I have the user manual but nothing in there about recovery. I have sent 3 messages to them over last few days but no reply all I can do is send more messages
[Android Head-Units] wybitny2:
The problem is what processor you had, they are delicately modified, which will not allow you to upload other software, I mean it can, but it will throw a black screen. here you have modifications in the Ossuret software, compare with Junsun. Send me a link to your software you got. I'll try to see what's in there, what's in your software.

[Android Head-Units] MaxuBo:
Hello, can you describe it in more detail. I have exactly the same problem, while I don't understand how to restore
[Android Head-Units] wybitny2:
Manufacturers protect themselves in such a way that they do not upload other software. Everything you need to think about what you are doing, as the radio known to be restored will give less known may be a problem. All we get is not complete software, it's an update. If it was software, you'd have to install it through your computer, then everything would be erased. To rollback you need to know the build.prop of the radio manufacturer, processor, and so on. You install the wrong update, you have a dark image, the radio will not start. because there are changes in build.prop
[Android Head-Units] MaxuBo:
То есть я не могу восстановить устройство, пока не найду обновление именно с этого устройства?
[Android Head-Units] wybitny2:
If you know the recovery procedure, you know that the processor is the same, you can take risks. Normally, if you are not lucky, it is 100% only the original update for this radio. If you upload the wrong software, the radio is not a brick, there is no update from the manufacturer and that's why it doesn't work. Если вы знаете процедуру восстановления, знаете, что процессор тот же, можете рисковать. Нормально, если не повезет, то 100% только оригинальное обновление для этой магнитолы. Если залить не тот софт, то магнитола не кирпич, обновления от производителя нет и соответственно не работает.
[Android Head-Units] robfox1975:
Sorry about the delay in replying I have been out all day this is the link to the software brogotek sent https://we.tl/t-UeDC40i6Ul

The firmware is in build.prop. ro.forfan.adaptans.enable=1

forfan.extscreen.height=720. Ossureta went outside. it will dump you Junsun firmware. I struggled for 30 minutes to do this. it is best to disconnect the cube from the radio with the ignition off, wait 5 minutes, connect the cube, press reset, turn on the ignition and touch the display with five fingers. The flash drive must still be connected before performing the procedure. https://1drv.ms/u/s!Atz6rzSxowxlkq99W5FLmsI-Ul7jDg?e=MaJqfW
[Android Head-Units] robfox1975:
Great stuff thank you...I really dont know what to do next and the seller still not replied
[Android Head-Units] wybitny2:
You have a link and the procedure described, at home with the power supply, the procedure took a while, because there was no power after the ignition switch, do as I wrote above. Junsun you uploaded the software early and it worked for you
[Android Head-Units] robfox1975:
Thankyou so much for this....can i just ask what is the cube??
[Android Head-Units] wybitny2:
radio power plug
[Android Head-Units] robfox1975:
I cannot get to that without take apart entire dashboard, so will try without first. if still not work will take apart dash board in the daylight tomorrow
[Android Head-Units] wybitny2:
I struggled for 30 minutes before the software detected me
[Android Head-Units] robfox1975:
So did it work for you only when you disconnected the power lead??
[Android Head-Units] wybitny2:
I can do it faster after disconnecting the power cord
[Android Head-Units] robfox1975:
I am just waiting for my usb drive to format, takes a while when not using quick format, then I will try, if not I will do it tomorrow and remove the fuse(easier than take apart dash and should have same effect)
[Android Head-Units] prochoice:
Hi everyone,I am new to this radio, I bought it a week ago and I would like to know if it came with the logos of the car brands included. They did not come on my radio. Another question is which is the best firmware or more stable.

Thanks
[Android Head-Units] wybitny2:
If you have Junsun radio, mediatek processor is the best firmware is 8667Q军灿UI02-国外-VHD720x1280_v23_20220801 . the logo is code 5678. You don't have a logo on the radio, I can get it from the software
[Android Head-Units] wybitny2:
now i know why your firmware crashed, you don't have checksum in 8667.upd. if you get the software and if you enter 8667.upd and there is nothing there, it means that the radio will fail. Something came to my mind, you would have to know how to enter recovery, do the format as it is there, the radio should start. the checksum is embedded in the stock software
[Android Head-Units] prochoice:
thank you very much, junsun told me to install this version that they sent me.

8667Q军灿UI02-国外-1280x720_v22_20221029.zip

but I will download the one you indicate.

Thanks
[Android Head-Units] robfox1975:
its brogotek, its not actually junsun...well brogotek is the seller on ebay https://www.ebay.co.uk/str/autogpsbrosmartek it was their firmware I sent link for....I have put software in before from them with no checksum on upd file and was ok

I changed the logo to mercedes benz when i first got the unit and still shows on boot before it gets to fastbook mode
[Android Head-Units] wybitny2:
be careful because there are higher versions but they are not correct, read what you downloaded. if you don't want to have problems install what you got. or send your check to see if what I gave you is the correct software
[Android Head-Units] wybitny2:
write to them, if not, I can get you the logo from the software, the logo will not show at fast start
[Android Head-Units] prochoice:
The problem I have is that when I turn the unit on, it loads home and then goes straight to the radio.

I don't know if this is normal behaviour. What I want is that when I turn it on, it stays in home without opening the radio application.

Is this behaviour like this?

Thanks again

All well so far, only thing is with this icon.

it keeps appearing after the car is placed in R Revers and i have to press Back to make it go away...

Anyone know what this red engine bonet open is? and how can i Stop it showing up?

THANK YOU

P.S. iv'e tryied many thing in the 8878 menu
[Android Head-Units] robfox1975:
Well I have tried the one you send link to and still didnt work, tried both usb slots.....I guess it is just not going to recover. I have been looking at the files. The ones that went wrong have revealed something I think I may have somehow mixed up the upd files as the link i sent you the upd file is empty with no checksum. The old files I flashed the upd does have a checksum but it is different than what an md5 check on the bin file, so it must have been a wrong md5

Md5 check on 8667.bin = 2f37deeb83621511b83211f0a7cce57d

upd file shows 617dbe997a0b85e339aaa95639f89006

I think that explains what happened
[Android Head-Units] wybitny2:
It is possible to turn off the radio application, but then I do not know if it will recover, I know that it will return to factory settings after a reset, why do you want to change it when everything is fine, you are looking for problems
[Android Head-Units] wybitny2:
You have a faulty bonnet sensor and that's why you have a problem, it's not the radio's fault
[Android Head-Units] wybitny2:
If you have older update files, try to upload older files, it should go back without any problem, you just need to know how to restore, you did this
[Android Head-Units] Ratralala:
Uncheck This
[Android Head-Units] Ratralala:
Thank you

But it’s not that for sure since a friend with same VW PASSAT has the exact same issue! I will ask him to take a picture on His 10” unit.. this ine is 9”.
[Android Head-Units] wybitny2:
I forgot about that, that's a good way.
[Android Head-Units] wybitny2:
Enter the canbus code 8878 there are door opening settings, uncheck and it is not recommended to display.
[Android Head-Units] prochoice:
I understand that the most normal thing is that it stays on the main screen, and the radio application does not open and it stays there. That would be the correct operation. I am not looking for problems but in other radios As in the original, the main screen is the one that should remain, not always opening the radio application or staying in the background.
[Android Head-Units] Ratralala:
Thak you

I will try later and come back..
[Android Head-Units] wybitny2:
enter the code 8878, others, change what is in the photo, the radio will not start
[Android Head-Units] prochoice:
I'm going to try it, thanks! The version you told me yesterday is valid for my unit.

Ok so by checking through all files one by one it seems that the 8667.bin file was from the official firmware sent by brogotek XRC-8667 升级软件 Q腾实UI多合一-国外-1280x720_v32_20220223 but the upd file with the checksum 617dbe997a0b85e339aaa95639f89006 matches with this version 8667Q腾实UI05-国外-1280x720_v36_20220825.

So I think it is certain that by mistake i put a wrong 8667.upd file on the usb and that has bricked it.

I think it has corrupted the bootloader and it will now not read the usb disk, possibly the usb drivers have been wiped as that would explain why no matter which software version i try nothing happens
[Android Head-Units] wybitny2:
Each radio is salvageable after uploading the wrong update. It's happened to me twice. Knowing the procedure, having the original update, the radio can be restored without any problem. I do not know what will happen if the control files are wrong, I do not know if the radio can then be saved. It only comes to mind. enter recovery mode, do a factory reset, somewhere I read that the radio will start because it has security files for such an eventuality. Recovery: press reset and hold for 10 seconds, after about 11 seconds in 1 second interval, press reset 3 more times and just put your finger in the display. Like in this movie.
[Android Head-Units] wybitny2:
It seems that the update 8667Q军灿UI02-国外-VHD720x1280_v23_20220801 should go smoothly
[Android Head-Units] prochoice:
Thank you! I have updated it and I already get the logos of the car brands!
[Android Head-Units] robfox1975:
I have tried this procedure, unfortunately all pressing reset does is cut the power, even holding reset does nothing apart from cut the power, the lights do not flash, the lights do not light up at all, they only lit up when the unit was running and the car lights were on

Pressing reset or holding reset restarts the unit....logo come up and go to blank screen with fastboot mode (pic 1)

Pressing reset or holding reset then tapping screen brings up "detected" but still goes to fastboot screen

pressing reset or holding restet then tapping hard with 5 fingers brings up "to recovery now" but then erasing then reboot to logo, then to fastboot screen

Before this happened all I had to do was press reset tap screen and got a screen like this

but now the scan udisk screen does not come at all

I just have to hope now the seller replies to me as I have tried every copy of firmware on this and other threads, I have md5 checked every one to make sure every upd file has the correct checksum

Before each attempt I have removed the fuse to totally cut power and waited 10 minutes or more before trying again and each time is same.

I think next plan is to take it to a phone/tablet repair shop if I do not get a reply from the seller
