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.
