Newbie having problems with installing on Samsung S7, device is not found

Well, quoting addresses the subject in general and the author in particular. That, at least, is my view. Accordingly, I was primarily referring to and communicating why I, like others, was reporting problems and therefore I couldn’t say, “hey, your install tool which I assumed to work did work in fact”.

However, since you couldn’t install /e/OS on your Galaxy S7 with latest /e/asy installer, my experience with the /e/asy installer could also give you hints, especially if you follow my postings on Samsung Galaxy S9 from 25.01.2021 und S9plus from 31.01.2021.

I flash all devices out of conviction and because I can, with the usual tools adb - fastboot - Odin3 - and, will continue to do so in the future. Especially since the /e/OS ‘Q’ aka /e/ OS Android 1’Q’ upgrade was released for the Samsung Galaxy S9 / S9+, problems with its use have been piling up on the /e/Forum. So I went looking for clues, first tried the /e/asy installer v0.11.2-beta with the Galaxy S9 and a few days later the /e/asy installer v0.12.0-beta with the Gigaset GS290. I’ve shared my experiences with it in the appropriate place. My advice was also followed, and so /e/ has a few more blissful S9 ‘starlte’ and Galaxy S9+ ‘star2lte’ as well as Gigaset GS290 users. And that is exactly my intention.
