Hello,
i have installed \e\ OS on my fairphone 3 using my Raspberry Pi. Now i want to go back to the stock rom. I have downloaded FP3-REL-Q-3.A.0054-20200929.092252-user-fastbootimage.7z. The manual says i have to use the FP3_flashall-file to install Fairphone OS. Unfortunately this file is a binary file for x86 CPUs (why did they do that? Absolutely unnecessary). I tried to flash the image files in the \e\OS style but get stuck at system.img:

# fastboot flash system_a system.img
error: cannot load 'system.img': Value too large for defined data type
I think i have to add the -S option like in the \e\OS manual. But i can’t find the right value and get the same error message every time. Can anyone help?
