Hi Piero
Thank you for the info its been a great help. I followed your instructions [HOWTO] Install /e/ on a Samsung smartphone with Windows easily
I have got to stage 8 part 3 and deleted the 5 items on the list. I got the red error message but the phone would not let me go back to Wipe to go back and select a different (exfat) system. I waited an hour but the and tried switching off and back on again. The phone just comes up with twrp home screen but I dont know how to get back in to the menus.
I tried the next step of installing /e/ rom to internal storage on phone from the PC but when I connect the phone neither the phone or internal storage are shown on PC.
Have you any idea what I have done wrong?
