Need help identifying my R4

[GBAtemp]

Hi ! Someone gave me his old "R4i SDHC" but i can't seem to get it working. And the sticker on the front of the flashcart is blank

Here are some pictures and screenshots that could help identify it:

(It shows up on a CFW 3DS but not on a OFW 3DS)

When i boot up the flashcart, i get a white screen, no matter if i have a micro sd card inserted and what's on the micro sd card.
