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

Well, at the end I was able to access the boot prompt after disconnecting the NVMe SSD and pressing the "reset" button next to the CPU.

I typed the commands like in the blog post 

Hit any key to stop autoboot:  0
=> ls mmc 1:1
  167509  idbloader.img
  335872  idbloader.spi

4 file(s), 0 dir(s)

=> sf probe

I flashed my eMMC with Fedora-KDE-38-1.6.aarch64.raw.xz, put the eMMC back and tried to boot MANY times but nothing happens even when re-inserting the micro SD card and removing/disabling the eMMC.

I think I didn't do any mistake while flashing the SPI but I can't be sure because I forgot to take a photo of what I actually did...
I think I'm good to order a pry tool on Amazon to I can access the SPI and follow the procedure I didn't want to do...
