EZ Flash Jr. not booting

[ShrimpRex]

So I bought an EZ-Flash jr. for a project to make an application for the Gameboy pocket. At first I tried using a small 2GB SD-card which just did not work as I couldn't flash it to the correct file system or cluster size. After buying a new 32GB card and flashing it correctly, the cart booted up exactly once. I was running the FW4-update .gb file that the readme told me to, but as I saw that the firmware was already up to date, I never started an update. Later, the cart refused to boot at all, just leaving me at "EZ FLASH LOADING..." indefinitely.

I have tried reformatting with the same and different file systems and cluster sizes, to no avail.

Any ideas?

Sorry to hear you're having this issue.

The fault you describe looks like the card can't detect the insertion of the SD card properly, can you check if the metal contact points of your SD card are oxidized or dirty, also please check if all the pins inside the SD card slot on the card are in normal condition.
