Hacking My R4i SDHC GOLD Pro doesn't work anymore in my DSi XL

[NMatrix01]

I started using the R4 just to have fun with my DSi XL, emulating DS and other Nintendo platforms.
Recently I discovered the ntrboot and decided to download some 3DS games to play on my 2DS. After all the process of downloading ntrboot, Luma and b9s, I tried to restore the R4 to its original state using the ntrboot_flasher.
The restoration was succesful, the 2DS reads the R4 normally, but when I try inserting it in the DSi, it doesn't read it anymore, and when I try any original game it reads regularly.
Is there anything I can do, besides buying another flashcart?

Sounds like a contact issue. It might be enough to clean the contacts (but don't use water for that!)

Use some alcohol and a q-tip to clean the contacts, I recommend you clean the consoles contacts as well as the slot does tend to collect dust over time. If that doesn't fix it then try sticking a piece of paper in front of the flashcarts label to give the carts contacts more support with the consoles contacts.
