Well, my EUR region 3DS is actually on 10.3 version where I installed a few legit .cia. Now I wanted to downgrade to 9.2 in order to setup emunand and rxtools. However in 10.3 I already have menuhax and ironhax both fully working. I know in order to make them work in 9.2 I need to install the 9.2 payload before downgrading. However this shouldn't be a big deal since I should be able to run brownserhax on 9.2 anyway. Should I downgrade both to 9.2 payloads before downgrading the system? Can I do this manually to menuhax after downgrading system by replacing .bin file in the root or should I delete menuhax before downgrading to avoid some isses like blackscreen?
