Hacking Black screen after triggering the GW exploit via DS-Settings on N3DS?

[Bonny]

Long story short: Have a N3DS on 9.0, installed the NVRAM-Hack, installed the correct mset_xxx.cia via DevMenu.3ds to SYSNAND.

Now, when i trigger the exploit via DS-Settings, the screen goes black, the GW-Logo appears and the GW card lights up ?purple? for a second, then black screen again and it stays that way. Why?

probably means your emunand is invalid/corrupted/too high version

try holding L while clicking ds profile and then recreating emunand

do not update emunand past 9.5 on n3ds

 

[Bonny]

I actually had no emunand installed. And because of this error, i created one. No change at all.

 

[Oishikatta]

are you able to get into the gateway launcher and boot emunand when using the cn or oot exploit?

 

[Bonny]

Yes. With the oot exploit.

Info: I first attempted to install the region.cia with BigRedMenu, and because this didn't worked, i then used DevMenu. Have i messed anything up?

Intresting: When i use the DS-Profile exploit AND hold the L button, i'll get to the GW-Menu (The LED of the Card lights up blue!). When i now click on "Boot GW Mode", everything works as it should.

When i just use the DS-Pr. exploit without holding the L Button, the screen stays black after the GW-Logo and the cart lights up purple.

Does anone know what the colors mean or why it won't work without holding the L Button?

P.S.: Used the Diagnostic Tool in GW Menu: Everything seems to be OK.
