I used the Up button on the D-pad to update via ROM and I ended up with a black screen brick, could someone help me with updating from 4.x to 9.2? It's for testing purposes. I have a hard mod! Also, I'm using a O3DS.
FBI through CN didn't work :/ Does anyone have any other ideas? Also, as stated in the OP I do have a hard mod haha
That should work... I guess your only other option is with a real cartridge.
Edit: Or update emuNAND, back up, inject clean firm0/firm1 partitions, and inject the backup into sysNAND.
I'm not sure how to do that exactly, could you link me a guide or help me please?
I don't really know much about it so I don't know if there are any good guides I could link you to, maybe someone else can be of more help or you can search.
