Hacking NDS Carts not working on O3DS

[Ratier]

Old problem was:

""""Old 3DS U , unknown previous firmware
All console lights turning on, but console won't start when the power button is pressed
Force Update doesn't work
NTRBoot works, I could acess latest GodMode9 and successfully CTRTransfered a 11.5U OLD.bin CRTNAND image using GodMode. Followed this guide:
https://3ds.guide/ctrtransfer.html""""

I was Still getting Black screen after ctrnand transfer so Fixed It by following This tutorial:
https://3ds.guide/uninstall-cfw

New problem is that none of my 3 NDS cartridges Works (3DS cartridge Works). When In tried to play them, got Black screen + Home Menu sounds. Haven't done any softmod since The unbrick. After It The only thing I did was update from 11.5 ctrnand to 11.6 using System Settings

How to fix This New problem?

Install CFW again then follow the DS section of https://3ds.guide/troubleshooting. If the console won't turn on again try a CTR transfer using Decrypt9.

CFW is not installed. I fixed this console for a friend and he wanted no softmod in the console

If you want to fix it you need to install CFW again. You can uninstall it later.
