Junsun V1 PRO 2GB+32GB UI3 Firmware

- Start date
With all that UI3 discussion, the Chinese have forgotten the most important functionality - safely switching the app while driving.

Did you tried it on your normal v1 2g 32g wifi? Is everything fine with your device?

WIPE DATA CACHE - RESOLVES BOOT LOOP
V1 (NOT PRO) 2GB+32GB WIFI - CPU MT8227L
Problem description:
Installation of a 3rd party launcher app (CarLauncher) has overwritten/updated a couple of system files.
Result :
Google play services stoped to work/disappeared and for the next restart the device stucked in boot loop in addition it has drained the battery of my car until morning. I guess the HU cant totally switch off with this error and behaving like a hibernated system.
Solution:
Right now there isnt any known method for this version of the HU to restart in recovery mode to make a wipe cache but . . . .
There is a working method to force the HU into update mode.
-Get a paperclip or needle
-Get an USB flash drive 1-32 Gb, Format it with FAT32 file system with the default volume size as it is provided by WIN11
- Open the link (provided by JUNSUN support)
https://drive.google.com/drive/folders/1QGzYyTV2_S7W2wmr7mP3uSgsWAxzyONb?usp=sharing
-Extract the ZIP file and copy all 3 files to the flash drive root directory.
- Get in the car and connect the flash drive to the 4 PIN USB outlet.
-Put the key into the start lock and turn to ACC/Power on wait until the boot logo comes up.
-Take the paper clip and press the reset button 1x, just press, dont hold
-The device will restart and when the boot logo appears again switch the power off/ turn the key/ ignition off immediately.
-Wait 10 SEC and turn to ACC/Power on.
-If everithing went well a "green loading bar" shuld appear on the screen with the tex "UPDATING" or something similar, i could not read it properly because it was visible only for a couple of second due to the size of the upgrade files ~2kb . I think these files are something that is like ADB (Android Debug Bridge) and initiates an update recovery command.
-The update took me approx. 5 mins.
-After the update all 3rd party application will disappear, eventually its like a wipe chace.
So far this is the only known working methode to get out from boot loop without flashing the HU.
Ps.: If it does not work try the other USB outlet or try another flash drive. If it still does not work dicsonnect every cable from the HU and reconnect only the power supply and USB and try again all the combinations that i previously mentioned.
I hope that it was helpfull for those who had or has the same problem.

Junsun V1 2GB+32GB - WIFI - CPU MT8227L - MCU: T3(L) // (NOT PRO, NO 4G)
https://forum.xda-developers.com/t/...i-cpu-mt8227l-mcu-t3-l-not-pro-no-4g.4519201/
Hello everyone! I purchased this JUNSUN device, connected to the Internet at the first launch and updated the software. I don't know how to adjust the backlight of the touch buttons, and I also don't get a password to log in to the developer. Who has such a version, who is like a community?

USB disk must be FAT32! If youre using big size disk (more then 32GB) use any program for format FAT32.
FAT32 format program link: Guiformat
