Hacking [WIP] Complete Custom Firmware Guide

if i have a japanese 3ds, do i need a japanese version of cubic ninja or would a US version work?

sorry, you'll need a Japanese copy... you can sell it afterwards once you have at least the 4.5 MSET installed though so it shouldn't be too much of a hassle

Why wouldn't it work anymore? Also what trouble are you having with the browser method?

someone in another thread told me it didnt. well I just tried the FBI method and now that've installed it the DS profile just crashes and makes me restart the system

the browser exploit would me take me to the website
and I would get something like this

but after a couple of seconds it would crash and tell me to restart. I would but then the DS profile wouldnt load rxtools it was just the thing that lets me edit the ds profile

You haven't downgraded your MSET then

In the guide, o3ds > with browser > step 8 then reinstall with the browser method... Also do you have the proper code.bin? And try a different website like the one in step 9 of the with browser section

yeah that was the first thing I did. I opend up rxtools again to be sure and went to downgrade mset again and it says "MSET is already in its exploitable version. There's no need to upgrade"

 

[dark_samus3]

Hmm... Interesting

 

[BMO]

Hmm... Interesting

yeah I think I'm just gonna give up on it. I'm fine with the internet browser exploit to load rxtools for now

For kicks try installing Cakes and see if that works

Question about the GBA firmware patching. Is it necessary to install on both sysnand and emunand? Where should I be installing my gba/ds cia's?

If you want to play GBA games while booted into emuNAND you have to install them on BOTH your sysNAND and emuNAND. The way the GBA firmware works is it checks you sysNAND for the CIA that you installed even if you're launching from emuNAND and the emuNAND GBA firmware checks the signatures before launching so the game and GBA firmware must be on emuNAND to start launching but also must be on sysNAND to continue working afterwards, hope that clears it up

Oh, I thought I heard from someone else that I can run them straight from sysnand. So that's not true?

Yes you can run them straight from sysNAND if you want, the above was for emuNAND users, sorry about that

No worries. Thanks for clearing that up. Is it safer to run one way over another?

I personally recommend running emuNAND as you can update it, back it up and restore it easily and if you do something dumb/risky you don't have to worry about bricking your 3ds, just your emuNAND

download the MSET downgrade package from "that ISO site" for your region, get the 4.x one because 4.x is much better than 6.x, unless you have a 2ds in which case the 6.x MSET is the one you want

Why is 4.x better than 6.x?

 

[dark_samus3]

Why is 4.x better than 6.x?

In general there's more support for it and firmlaunch (the exploit that allows CFWs to boot reliably) is more reliable under 4.x

Thanks for the reply! I've always wondered which is better but never got an answer haha

No problem

EDIT: OP updated, Cakes guide is now up to date and has a much easier method of obtaining firmkey.bin, serious shoutouts to the Cakes developers
