Can I downgrade my browser on my emunand 10.4 rxTools to version 1.7567 (9.2 browser) while staying at my current firmware? I tried installing the cia with FBI but that doesn't seem to work: I get an error. Any help would be appreciated
I'd make a backup of your entire emuNAND first.
If you want a backup of the browser, you can download it with 3DNUS I think, just get the 10.4 version. That would be easiest.
