@isaac , why don’t you answer my question? You also want me to answer your questions, don’t you?
You guess it »Seems to be A.« ‘a-only’ ROMs cause my ‘a3y17lte’ to bootloop. Well, I know defeinitively that my A3 2017 SM-A320FL a3y17lte status is ‘a/b’ because whether I use version eOS-Q-20210225-UNOFFICIAL-treble* or the current version eOS-Q-20210214-UNOFFICIAL-treble_arm64_bvS - it works.
That twoTrebleCheckApps show mixed results is well known. Through trial and error I got to the goal:
I just inserted a SIM card into the ‘a3y17lte’ that is turned on.Immediately the system reacts and asks to enter the PIN. No sooner said than done. Now the ‘a3y17lte’ asks me to reboot. Okay, done. Now my provider is displayed, the LTE is ready for use. A control call confirms that it is ready to receive. Calling another phone number is also possible.
Résumé: The most important function of my cell phone Galaxy A3 2017 works as it should: I can make calls via LTE and GSM. Calling via SIM data-package and WLAN also works.
