Ooookaaay.

Let's put this issues and miseries with old units aside and solve this.

So many of you have problems with restarting unit / self erasing unit at boot, due to self loading Google services and updating on their own (which in next restart erases all memory /state config and sets to default factory settings).

So here is a fact. Google updates it self and its services as soon you connect unit to internet it takes a while a few minutes but you can see progress in status bar when updating.

When Google update specific GOOGLE SERVICES (app responsible for all Google apps that are connectd with google) sometimes updates fails and Google services is not same lately version (check for that in car settings/ app settings / Google servies app or Google). When updating and setting owner of device - Google account - fails whole system fails.

Here is a partial solution to try and test for various units with 8227 chipsets.

I have old 8227L unit home and have succesfully managed to reinstall Playstore and G services but if this will help to solve issues with erasing / restarting we will see on your units!

- Detach all usb drives or sd cards attached from unit for now.

- Go to root directory (use file manager default app or File manager+ app, if device not rooted use second app) and find leftoovers of instalations from Google :

- files like Google folders with no data relevant to system and folder CACHE - delete all !

- delete non essential files and folders (only Android folder must remain along with Music folder and importantly navigation software folders) , logs and settings.ini , factory_settings.ini files etc.

- DELETE CACHE MEMORY of every single Google services that are in APPS menu (DO NOT DELETE DATA, only CACHE memory of apps)

- next step is to disable Google and its services so system cannot update them when unit is connected to internet or online

- while Google and services disabled - download this file https://drive.google.com/file/d/1pnqyE9PQg8rn8gSSm7GfE-Zgghu3YGAw/view?usp=sharing from laptop or PC (playstore latest) and transfer it to unit on root directory and install from there (activate third party software installation permission - give permission - if unit fails to install)

- remove USB drives or SD cards from system so that system cannot write on USB memory or SD card instead of main unit memory

- ENABLE google and its services again

- when new playstore apk installed, enter playstore and connect unit to internet, let it update by itself or update Google and Google services manually - do not restart unit untill finished all!

- set your desired Google account (tweek all in Google menu of car settings) and connect to your account

- set everything else - icon arrangment , radio stations, wallpapers, install desired apps etc.

- now for restart of unit and saving new state to a unit memory :

- go to factory settings with pin 8888 - then go to other menu where setting MEMORY/LAST STATE OPTION IS ENABLE THAT OPTION - MUST BE ON

- FIND OPTION INSTALL AND PROTECTION - INSTALL must be ON or value 1 PROTECTION must be OFF or value 0 , AUTOLINK option if exist turn to ON, MCU option set to value 1, dithering option set to value 1 or ON, Bluetooth ver (version) option set to 4

- Bluetooth SYNCH option must be ON or value SYNCH , not ASYNCH

- return on main menu of factory settings and enter one (I don't know what is called in your unit) that looks like USB drive picture -> drive / memory picture - press it , it will say (if no USB drives and SD cards attached) failed to save memory or someting like that , which is good , it means that it will write memory on units main memory instead of external drives (if USB drive or SD card is in place after reboot deletes all files and replaces them from actuial ones in external drives and then sets default factory settings again and loses everything)

- close factory settings window as process (do not hit SAVE button on upper right corner - it will restart and lose all settings and tweeks again)

- go to car settings / about unit or system info (till you see pad where you type in pin for factory settings) and enter code 1414, unit will shutdown ad save last state that you configured (untill successfull boot USB drives or SD cards must be detached from unit !)

- after bootup when in Android test everything and enter playstore - if your account is still set and is working you have now fully working unit, try rebooting a few times with code 1414 and see if problems will occur again

And that's it ! Hope this bible text wil help you guys.

Report here is someone succesfully fixed the unit.

Fingers crossed.
