Is there a way to put the roopieee image on a SD card? I have currently nothing with a SD card slot expect my android phone. I could connect the android to a MacBook with usb … would that be enough to access the internal SD card and flash the image von the SD card?
Or could I connect the pi4 with the SD card to the MacBook?
I doubt any of those would work, SD card adapters arent expensive

If you are going to use Ropieee then you should invest in an SD card reader and a couple of extra SD cards. It will make things much easier for you. Occasionally I have had to reinstall the software and having a card reader makes it much easier. I like to have a couple of SD cards around so I can remove the current card and install an upgrade to the new card thereby giving me an instant fall back just in case.
