I have Tab S5e and have no connection for adb. It charges okay, I believe, although I don't know what charge rate is supposed to be. For computer connection a Ruideng meter shows 4.899V & 0.4779A with D+=1.12V & D-=0.00V . In download mode it works with 4.883V , .5006A , D+=0.02V , D-=0.02V while connected to PC. So I am thinking hardware is not broken but it does not work booted to android or recovery. It is the same whether on stock or custom firmware, locked or unlocked bootloader. Flashing stock firmware thru Odin does not fix the issue. Can anyone point me in the right direction to geting adb working ?
