Hacking ErrDisp error on monster hunter generations game cart

[Duesjacky]

I have a US monster hunter generations game cart and it always gives me this error though other carts work fine
1. I've try it on 2 different systems, a modded new 3ds xl and non-modded 3ds xl, still that error
2. SD on my modded one is a freshly new SanDisk 32gb, other is a 64gb fat32 Toshiba
Can anyone help with this?
3. My modded n3ds xl is on the latest luma and gm9
Really appreciate if anyone can help me fix this.

Cartridges have been increasingly having problems working recently.

If I recall, it's to do with bad soldering at the factory, and I heard that reflowing the solder can fix them.
