Hello I have a problem with my car stereo, when I use the phone with carplay it conflicts with the bluetooth and it feels bad.
The bluetooth is configured when the radio is started and I have installed a widget to disable it.
I was wondering is it possible to install a firmware that keeps the bluetooth off even after rebooting?

This is my device:

Hello,

My device reports as android 11 even in cpuz but when i connected my gmail to it, the 2 factor authentication reported it as android 8.1. it seems the manufacturers are able to hide the version from cpuz too. I would like to root and install a different rom if possible

Mine has 4gb ram 16gb rom and the screen is 1280x720

The brand is called X3

There is no need to install new firmware, just go to or find folder Apps and deactivate Bluetooth there and then see if this helps.

As Bluetooth is maybe not visible by APPS folder there is a process called "mainUI ts com" deactivate this one. Or install a new one that is causing no conflict (I believe it is called : 3.com.ts.com.mainUI8).
You will find this system process here : https://forum.xda-developers.com/t/...and-other-stuff.4167669/page-15#post-86750371
Install thru apk installer and restart device.

@Anton TNT Hello, I installed this but the settings are not saved. User settings reset every time I reboot. What is the reason?

 

[pablo241]

I tried all the options and nothing worked.
I bought a carplay dongle on amazon, now everything works perfectly.
PS: for those who had problems that the radio did not memorize the volume, radio stations etc. you have to go to menu 8888 and put" back option" ON

Go to factory settings and deactivate option PROTECTION, activate option INSTALL , all from factory settings/menu OTHER, set canbus decoder menu for right PSA settings, and finally delete any mem.ini and other log files written in internal memory root folder, then configure your device icons, nvai volume etc. and restart device (while ignition key is NOT AT CONTACT MODE but in car engine on mode). Sometimes in order to write in memory you'll have to do it a couple of times before it saves last state in memory. Also before configuring anything and restarting there must be no SD cards or usb drive attached in ports at all.
P.S. you have also MP mode settings in factory settings if you want to save settings to USB or SD card, but must be all times attached in port when you start engine and turn off, and must have at least 8GB of space.

it does not work. No problem with that, I'll fix it. There is one more thing I am wondering about. What is my developer model?

 

[arthur61]

İşe yaramıyor. Bunda sorun yok, düzelteceğim. Merak ettiğim bir şey daha var. Geliştirici modelim nedir?

Hi, deactivate DSP effects (value no DSP) or Amplifier (value-0) in factory settings (entered with pin) and see if sound will work then, if not, return to old settings

search on net for firmwares with name "zxdz_2020.03.18.10" , you will find a site containing this kind of firmware and install it.

@Anton TNT you seem to be the powerhouse of knowledge here...

I have an 8226L head unit that randomly bricked the other day while I was reworking a theme... I have been unable to raise the seller of my unit in any meaningful way - and the amazon listing for it has since been removed -a factory reset didn't work and so I took to the internet to find a firmware to flash.

It is a ZBARK unit for a 2013 Prius - 8227L based - 2GB RAM/16GB ROM - and I have managed to flash a few different firmwares to it - however my DSP settings in each case WILL NOT save for the life of me! I keep restarting my car to find out my bass is maxed out and even after following these instructions I am still having issues. Help!!!

Update - I see your previous comments regarding removing SD cards / USB drives, setting settings and what not in a proper order after a flash - and I am still having issues with my radio and DSP not saving anything after reboots.

I am not running original firmware on my radio - but everything works as it should on this ROM aside from this ... the seller of my radio is not being forthcoming with a firmware update... sadly.

This issue seems to persist no matter what ROM I install - and certain settings are surviving after a factory reset which I find odd... while others aren't even surviving a simple reboot. It's quite perplexing.

Thanks in advance!

hello, i have this head unit for seat no working radio,youtube navigation,and all no sound no anything just on
need help plz

 

[monsieurtalbot]

Little update here - I COULD NOT get the radio settings to save - no matter what I cannot get presets to save - thankfully I rarely use the radio so this is not a big deal for me.

However after following the directions Anton laid out - and going through each part of the factory menu - and setting settings... eventually my DSP / equalizer settings started storing.

It took a LONG time to get it going - and it is completely counterintuitive... and there is no way to tell it worked other than lots of resets and reboots... but I finally have my radio back the way I want it - after 3 hard days of research and labor.

I even made it "better" than it was before - as the new firmware I found is 2 years newer and quite a bit faster than my old firmware.

SO - I guess I win in the end. Thanks @Anton TNT for the diligent posts which eventually led me to the correct solution - I'd still love to get my radio settings to stick - and more-so understand why this happened, but in the interim, this is solved for me!
