i got this tablet fom a client, when i plug it with my original galaxy s8 cable, just showed it was charging, after a few hours, the tablet turned on by its own. i never knew what i did, maybe was the cable, but im not sure, i didnt use either the fast charging brick because it didnt recognized just to add, i used the method that i saw on youtube, setting it on download mode, and helped to boot again.
Actally what I did I used my personal charger and started to working again a fast charge and a closely similar cable works
Sometimes the customers charger and/or cable may be at fault. With a good charger and cable if it gets stuck on the charging bolt for a bit it usually means battery is too flat and needs time to charge up.
