Guide_3ds: DS(i) mode still non-function despite new cia

A few things to try.
Reinstalling TWL_FIRM as a CIA (use 3dnus to download title 0004013800000102 and make sure to check the "pack as CIA" check box.)

Reinstalling the version data for TWL (I doubt this has changed, but is worth a shot) title 00048005484E4C41

Reinstall any remaining TWL titles if none of the above work, titles 0004800542383841 and 00048005484E4441

From there, report back what worked, if anything

Mine is working now installed the CIA on 2 of my 2DS and was able to play DS games and configure DS connections, thanks guys!

Yeah, perhaps the guide should include reinstalling TWL_FIRM/version/titles too along with the whitelist in case this happens.

I can't get 3dnus to work for me, I have no idea what I'm doing wrong. Can you post the TWL_FIRM as a CIA file like you have with the original problem?

| Title ID | Version | Description |
| --- | --- | --- |

Thanks @iuzwpr2p39rh7w!!!! 'Old 3DS TWL_FIRM' or 'Version Data' didn't work after installing them but I tried the other two together and my DS carts booted up as they should. I may have needed all of them? Hard to tell. Anyways, cheers everyone! Love this community!

Since it worked for @doug34 this issue will be closed, installing all of the TWL cias will be added to the guide

DS Internet was the last thing I installed and was necessary for Pokemon Black to load.
Thanks a lot
EDIT
I restored a NAND backup with only the whitelist CIA installed already and confirmed that just installing DS Internet, without the other three, allowed Pokémon Black to boot.
Strange because it was present and at the right version in the title list in FBI.
It could be worth keeping the others in the guide in case other people need them but they may be unnecessary

FBI would have reported the correct title version... What's going on here is, TWL titles are installed in two places, one in CTRNAND (where the version number is read from), which you transfered, and the other in TWLN... What this means is, while the one in CTRNAND got updated, the one in TWLN did not. So the system seems to get stuck in some sort of loop. Installing the correct CIAs installs it both to TWLN and CTRNAND, fixing the issue

Added all titles to the guide.
