What I'm trying right now is completely experimental and I want to ask you users of GBATemp before I carry on, to see if anyone has some experience with this. So I've downloaded the 7.x internet browser cia from 3DNUS, the last one before the 9.5 browser update. I want to get this installed on 4.5 sysnand, so that I can have access to the browser exploits for specific games like ACNL. If there is a way to upgrade sysnand to 9.2.0-20 up to 9.5.0-22, that would also be great. I fully understand how to install a cia to sysnand, especially now that Gateway made it ten times easier with the new 3.2.1 update. I just don't know WHAT will happen after installing this cia. I just finished installing the 4.5 mset on my N3DS, so installing this browser cia on my O3DS should be a similar process. This will update the browser itself, similar to "downgrading" the settings(mset). I'm still pretty skeptical about installing this, since this will be done on my friends 3DS. It'd be terrible if this bricked. I feel like even if you have a NAND backup, it's still pretty hopeless. Any input would be appreciated, hopefully someone's tried something like this before. Really looking forward to getting this done.
