Hello, I have a Junsun V1 Pro with 8-core MTK8259 processor, I wrote to the seller to send me an update to UI03, but he sends me a media update with 4-core MTK8227 processor, which update is not suitable for my media. Can anyone send me the latest firmware update, because all the links I find are no longer active, I would be very grateful if you can send them to me by e-mail - [email protected].

Hello,

First of all, I apologize for the English, since I am using a translator.

The vendor of that browser sent me the same update package that you posted, but I would like it if you could explain to me how to install the update.

Thank you so much

Copy the bin and upd files (which are inside the zip file) to an empty USB stick - directly on root/top level. So don't create a directory on the USB stick.
Plug the stick on your head unit. A prompt asking you to perform update should appear automatically.

Hi guys, where did you download latest firmware for V1 Pro 4/64 android 10 from?
That is the DEVICE . I am facing and some other troubles with this piece of sh*t like not working steering wheel buttons controlling the board computer, sound is too loud even volume set to 3-4 and EQ set wit low bass and there is a bad noise coming from speakers when volume set to 0-1, but will solve problems one by one. Let update to latest firm first, thanks

for steering wheel you need to choose the good canbus settings. i used 8259P_军灿UI02v1280x720-国外_v27_20211201.zip for my device. but before update do a full backup.

IAmNotMe01 canbus code is set to 145 (in my case mazda 6). SW buttons control the android device and not able to change options in the board computer of the car. Normal behavior is like this on the video​

How do you do a full back up of system before trying new firmware. Don't want to brick system but I am hoping new firmware will fix my Bluetooth issue.

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.

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".
