I have an old 3DS that not start any game or program about DS mode. My 3ds doesn´t start any games DS and aplications about DS. I tried with TWLFix-CFW and then update system but it doesn´t solve the problem

Hi, Thank you for the answer. I tried update system after unistall TWL modules in TWLfix. I found this page https://wiki.hacks.guide/wiki/3DS:TWLFix/Alternate is talking about alternative if unistall and update system not work. So i will try this option and then i will talk about the progress of my 3DS.Try performing a system update first, it'll reinstall any missing/broken TWL modules.
This didn't work, but i can found the problem. The problem was module WIfI in where is the NVRAM. When pass the test call ctrcheck, the program found the critical error in NVRAM, so i replace the module, and then ran the 3DS_NVRAMtool press the B button and then X button. After this i ran the TWLFix-CFW and then update the system and finally i can play my DS games.Hi, Thank you for the answer. I tried update system after unistall TWL modules in TWLfix.
