So I’m currently having issues with my android head unit but just wanted to ask about the problem where any setting gets reset/reverted after reboot. Can someone please help me with this issue? I have tried contacting the seller, in which he showed me to change (for instance) the volume settings from within the factory settings, but that still doesn’t work. I know that it’s possible to do it because I was messing around the other day and managed to save a few settings after reboot but can’t remember how anymore. If someone have a solution please tell me.

Same problem here did u manage to solve the problem with reset settings after reboot?
DAMN! That might be it, as In fact i did have connected usb music stick for a while and the settings stayed, but from a couple of months I disconnected pendrive and from that time it seems to be no remember and restore settings randomly tru the use of car and radio
Gonna report back
We're waiting
.I'm just wondering if there's a way to change the location to save settings to the head unit itself, so if anyone has a tip....
Maybe I already found the option (just not tested yet).
1. Open your Android device's Settings app.
2. Tap Storage & USB.
3. Tap Internal Storage.
4. Tap the menu icon (three vertical dots).
5. Tap Change where new content is saved.
6. Select a new download location.
7. Tap Done.

There are already a few threads explaining that app and factory settings gets stored on USB drive.
After connecting a USB drive the first time Android asks how to handle the drive in a status bar message.

So I have news.
I connected the usb stick and choice in radio use as internal storage and then after setting all up audio eq all my setting in menu 8888 i did click export to usb or something like that option, and it seems to be remembering so far.
BUT
There occure other problem, before the pendrive trick I did try to figgle aroud in setting options and I think i break shutdown option or so, as yesterday my car battery died.
And I can clearly hear the fans working after car engine off and its somehow working in background.
The normal in settings sleep mode is set to 0 minutes so my guess I did break some settings in hidden option 8888
For now, I am charging my battery tomorrow I will try to post some shots/video of my unit UI and options

So I manage to fix all my 3 problems
1. Bluetooth dissconnect/ cant see and pair
Go 8888 in the advanced menu and OTHERS, add Bluetooth mode 2, INSTALL, and SYNC additionaly manualny add Bluetooth name, after that unit gonna show pin core, connect no problem and for me it keeps Bluetooth active
2. Settings radio eq doesnt remember
Connect fresh fat32 USB stick and choice use as external storage, set all app find see if after reboot it remember
3. And here is extra step as for me the settings doesnt remember even with pendrive connected, I think that i figgle too much on settings and the file that is suppost to keep settings Save override
So go to 8888 and click the ERASE ALL CONTENT
What IT did for me it reboot unit and reflash firmware and factory reset
That way the pendrive trick after setup IT remember all radio station and eq settings
My guess is IT delete broken file that interfeer with Save settings.
Thank you @Blade6100 for all the hints and tricks

Junsun V1 pro won't save settings
So far i've tried:
Adding USB drive as Android space, also as travel media for music
Reset
Update to v61
Manual save to USB drive via 5555 code
Manual save to SD does not work
After restart head unit loses radio stations, equalizer settings
Car is Peugeot 207, Junsun V1 Pro with 64GB of storage and 4GB of RAM
Any tips are welcome

Don't set the USB stick to be your main storage for apps and other Android related content. I'm sure you will find the Android setting via Google.
Disconnect all USB stuff.
Reboot the unit and change setting. Reboot again and check if settings are still stored.
Please be aware that changing factory settings will delete other settings like radio stations and (maybe) settings if the Junsun launcher (if you use this crap).

Thanks for the reply! Changing factory settings resets radio & etc is useful information. I removed USB memory stick and restarted the device. With entering code 4 restart still resets radio and EQ. Is there any other method for restarting device?
All my information are useful.
I created an app Reboot.apk which restarts the device without the need to keep code 4 in mind:
Junsun V1 - start equalizer/AUX/BT music/CarInfo... from launcher
The app equalizer.apk starts the equalizer (activity com.ts.main.Media.ADASMainActivity): EqualizerShell.apk starts the equalizer (activity com.ts.MainUI/com.ts.set.dsp.SetDspMainActivity) via su shell command. See post below for further...

But to be honest I don't think code 4 will reset the device. Only if you change and save a factory setting.
Most likely you are right. Stations and EQ settings still dissapear. There was some talk about wiring. Mine is connected only with manufacturer plugs, no seperate wires are connected. Maybe there might be the problem?All my information are useful.
