Hi there ! I tried /e/ os and would like to reflash the stock ROM to test something.

I am afraid you have bricked your phone. Have a look at this thread about a bricked phone .

I am just so annoyed and sad about the situation… If there is some examples where somebodies have reflashed the phone by a repair store it should be great ! I have buy the phone from a big arket store and I don’t know if they will understand the problem

I moved your topic here. You have to contact Fairphone, only their repair center can help you. Maybe just use the repair portal, when possible, Important for the future in case you want flash anything, always check the SPL and ensure you never install an older one when you want to relock the boot…
