First of all thanks to everyone who contributed to this great project. I already installed it on my previous smartphone and it worked like a charm, unfortunately it broke last week.
I bought a brand new Gigaset GS290 with the intention to run /e/ on it so I got it off the box, followed the instructions on the easyinstaller and went through the whole process until the screen that says “installation will be over once the logo disappears” (or something like that). That screen was on for at least an hour but my computer (old lenovo running ubuntu) decided to stop working at this moment for some reason. From then on : nothing, just black screen, pressing volume up, down up and down along with power button doesn’t seem to do anything and the phone isn’t recognized by the computer. Adb and fastboot say no device/emulator found.
if anyone has a solution to unbrick it, I’d be very grateful.
It said the download was successful but unfortunately, the phone still won’t start. Screen is black and it doesn’t react to pressing power and volume buttons.
Here is the code if it is of any help to understand the problem

Yes I tried flashing the stock ROM using SP flash tool, on both ubuntu and windows 10, and none of them worked. The phone was fully charged and I tried with a bunch of different cables. Unfortunately I don’t have access to a windows 7 machine and I’m guessing using Windows 7 on a VM wouldn’t change anything. I also tried contacting Gigaset but they’re clueless.
So after many hours spent trying to unbrick my brand new GS290, I’m quite disappointed to have to buy another phone.
And as I’ve read so many threads of people bricking their gs290, I’m thinking it could be a good idea to have more explicit warnings about installing /e/ on it. That could save some money to users having to buy another phone after bricking theirs, but mostly prevent many machines from being unusable after a failed installation.
Anyway, thank you very much Iain for your precious help!
Quick update to say that my GS290 is unbricked Huge thanks to @smu44 for his expertise on the matter and for taking the time and the energy to help me out. My phone now works perfectly on /e/ OS 0.17, apart from a few account synchro bugs and some wifi issues but nothing major! I’m really happy with it and can only recommend the /e/ os of the GS290. I’m just hoping no more phones will be half-bricked in the process so that @smu44 doesn’t have to help the whole of Europe unbricking their phones.
Apart from that, having tried SP Flash Tool with Ubuntu 20.04 and Windows 10, multiple USB-C cables and with the battery charged, Windows 7 seems indeed to be the best solution!
Thanks again for helping me everyone, from a happy /e/ user!
