You can’t use the board to access the sd card while you’re updating the board.
The software that lets you access the sd card via USB is what you’re A) stopping from running when you go into bootloader mode and B) replacing.
Needs to be on your computer.
You need to copy the proffieOS folder off the SD card to your computer and run from there. ( If I read your issue right)
i fixed it. i just reset everything to defualt and literally restarted everything and then moved the folder and such. had to fix that one error involving the missing '{" still but its fine now. thanks for the help its been a long time since ive had issues with proffie so i have lost all my knowledge on how to fix them.
Glad you got it sorted and that things are working.
