IF you want to update your headunit to the latest fw, you have to completly uninstall all app through the service menu - > app installation.
DElete data, then delete cache, then delete app.
After all app is deleted, you can Factory reset the android part also in the service menu. Once this is done you can also factory the head unit it self through the settings menu in the head unit.
OK, thanks a lot for the very detailed feedback!
My situation is that i ONLY need/use IoniqInfo which is rather small and i guess not the biggest trouble maker, but still i would remove it completely (+data/cache) before i visit my hyundai partner for the next update. Is it still with only this single APP required to go through this procedure?
Why is it required to FACTORY reset the android part if already all apps are removed - and data space is available again?
btw, factory reset needs to be done twice? directly in service menu (android) + in the "normal" HU menu somewhere in settings i guess?
