Hacking which R4 firmware to install

[xunsus]

So i have a O-3DS ver-11.4 that cannot read my R4 and another ds that can so i need to update it the problem is the R4 is a pretty old one (it's a R4 SDHC labeld NEW) (also the menu that worked was called "r4isdhc-whiteEnglish1.51") that the official site said that it no longer makes ; so i don't know what to do ?

if it's an R4i SDHC you can run it by using TWLoader or NTRLauncher
