Followed the blog post to install Fedora: PBP not booting anymore

[koenigs]

Hi guys,

So I had Manjaro installed on my eMMC for a while now and I wanted to switch to Fedora.

I went to the official Wiki which redirects us to a blog post from 2021 which I followed.
I flashed the firmware to the micro SD Card

Code:

$ sudo spi-flashing-disk --target=pinebook-pro-rk3399 --media=/dev/sdc1

I didn't really pay attention to the error messages at the beginning nor at the end, I just saw that some data was copied to the micro SD card so I thought it was fine.

Then I opened the case of my Pinebook Pro, disabled the eMMC using the switch 24 (I should have just removed the eMMC actually).
Then I tried to boot with the micro SD card inserted and... absolutely nothing happened even after pluging in the DC barrel.

Now even with the micro SD card removed and the switch 24 enabled my PBP won't boot.
I tried to check the content of the micro SD card with my other laptop (I'm on Fedora) but I'm not able to mount it.

Code:

$ sudo mount /dev/sdc1 /run/media/koenigs/sdcard
mount: /run/media/koenigs/sdcard: wrong fs type, bad option, bad superblock on /dev/sdc1, missing codepage or helper program, or other error.
       dmesg(1) may have more information after failed mount system call.

I don't even understand what went wrong actually, I didn't enter any command to flash the SPI with the firmware from the micro SD card, it just didn't do anything so I didn't even get the opportunity to try it...

Is there any way I can recover from the situation?
I'm a bit worried I screwed my SPI, it seems a bit tricky and risky to follow this procedure so I'd like to avoid it if possible.

Thanks for your answers

EDIT: I understand what I did wrong, I flashed the firmware to the partition sdc1

Code:

$ sudo spi-flashing-disk --target=pinebook-pro-rk3399 --media=/dev/sdc1

I should have done it to the card card's disk scd instead

Code:

$ sudo spi-flashing-disk --target=pinebook-pro-rk3399 --media=/dev/sdc

But my PBP is still not booting after fixing the micro SD card.

Did I screw my SPI???
