I have a Samsung Galaxy Tab S3. What, apparently suddenly, has entered a start-up loop – Samsung's device name and logo screens follow each other indefinitely until there is no more energy or that I interrupt you using key combinations to start in download or recovery modes.
I have no experience with Android Development or Android. I am very comfortable with Linux terminal environments.
From now on, I tried to update the new Stock firmware with Odin. The returns from the Odin software indicate that the flash was successful but the bootloop persists. I guess the OEM and / or FRP lock might be the reason.
I've read that it's possible to disable these locks by using
adband I believe
fastboot can be useful too. But since I can not access my phone's settings to enable USB debugging, I can not find a way to connect to adb.
To be more specific about my question: is there a way to connect to adb and fastboot and troubleshoot / repair a boot loop with only access to recovery and download modes?
