Hacking updating sysnand with gateway?

[reiyu]

i have 8.1.0-0J, and at least i want to update to 9.2.0-20J since the 0J doesn't have the browser exploit, is this possible if i have all the update files? what installer do i have to use if it is? also, is it safe?

Install rxtools on your sd card and install fbi to sysnand and use fbi to install sysupdater and launch rxtools boot into devmode from its menu and use a 9.2 upgrade pack with it found on the iso site and run it. caution as this may brick your 3ds if you are not careful. Also it wont work from rxmode or gateway mode as it will brick your 3ds if you use it from there

rxtools dev mode is the same as gateway sysnand mode?

also forgot to say i have an n3ds.

There was this :
https://gbatemp.net/threads/guide-upgrading-8-1-0-0j-to-9-2-0-20j.384960/

But sadly it doesn't work anymore.

Some people are working on an alternative method right now

BE CAREFULL
UPDATEING IN GATEWAY SYSNAND MODE OR RXTOOLS SYSNAND MODE WILL BRICK YOUR 3DS
Use rxTools DevMode to update your SYSNAND
Install FBI then install SYSUpdater through FBI, launch SYSUpdater with the update in your SD and done

rxTools doesn't work on a 8.1 n3ds.

For O3DS 8.1.0-0J, it's unhackable since both mset exploit (*) and spider exploit (**) don't exist.
For N3DS 8.1.0-0J, it can only run GW or NTR 2.X.

* mset exploit exists on 4.1-4.5 & 6.0-6.4
** spider exploit exists on -2J(EU) ~ -20J(EU) / -?K(TC) ~ -?K(TC), if you haven't manually installed any web browser CIA
For an O3DS 8.1.0-0J,
"8.1.0" means "mset exploit doesn't exist"
"-0J" means "spider exploit doesn't exist"
So it's unhackable.
