Hacking 3DS cfw cannot proceed, likely due to bricked DS hardware

[falconzinx]

I've been following the 3DS hacks guide for installing a cfw using the Pichaxx method,
and successfully got up to the point of the Fredtool,
but got to a black screen when trying to access the Flipnote Exploit via "Internet Settings" -> "Nintendo DS Connections"

(in the "3ds hacks" website, under the "Installing Boot9strap (Fredtool)" page, Section II, step 17)​

Even before attempting the installation,
going through "Internet Settings" -> "Nintendo DS Connections" resulted in a black screen.
Running any DS game cart results in an error message that says:

"An error has occurred. Hold down the POWER Button to turn off the power, then turn it on and try again. For help visit..."​

I also tried the steps in "DSi / DS functionality is broken after completing the guide"

(in the "3ds hacks" website, under the "Troubleshooting Page", Section "DSi / DS functionality is broken after completing the guide")​

but did not result in any changes to any indications of DS hardware working.

Running any 3DS game cart still works normally though.
Is this a case of bricked DS hardware, and is there a way to fix this problem?

I don't get this part. It says "after completing" the guide. Without having CFW you obviously can't use the CFW version of TWLFix. If not already done try the non-CFW version of TWLFix. In case you can't get the DS(i) mode working with TWLFix the pretty much only option for installing B9S on firmware ≥ 11.4 without functional DS(i) mode is ntrboot. If you don't already own a compatible flashcart, I recommend buying the R4i Gold 3DS Plus with internal switch for ntrboot/DS games.


There had been cases of really bad DS(i) mode bricks (not repaired) in the past: [my DS Mode is Still bricked!] and [DS Titles + Flashcart nonfunctional (White screen)]

Good luck!

^Using the non-CFW version of the TWLFix had fixed the problem completely, thanks!
