Broken usb connexion Samsung S7 after upgrade (Herolte) - #2 by aibd
IF TWRP is ok, there is another way to apply the upgrade. Check the ability of TWRP > INSTALL to navigate say to the root of SD card. You can download the /e/OS ROM to root of SD card (SD card in a reader attached to PC) and then install from there.
