Hacking 3DS SysNAND possibly corrupt - Buttons messed up

[LordKail]

Dear GBATemp community,

As this is my first post, I hope it follows all the guidelines. I have been lurking on GBATemp for a long time but have never made a post. My first one is a ray of hope . Also, forgive me if I use incorrect terminology.

I have had Gateway for a year but did not use it too much. I had noticed that my friend accidentally updated my 4.2 EU firmware to 8.1 with SSB. I therefore decided to downgrade it to access the Nintendo DS Profile exploit.
Everything went fine and it downgraded just fine and when I went into the settings menu it was at 4.5.

After that, even though the tutorials told me to do it before downgrading, I decided to format emuNAND. And I think that's the point where I messed up my sysNAND.

After that, I noticed that whenever I went into Gateway, I could not access any other menu apart from the "Boot gateway/SysNAND" ones. What happens is, I press to go, for example, into Downgrade menu to restore my Sysnand and then it just pops me back into the Gateway menu. I have also noticed that my D-pad (the Up button) just keeps repeatedly pressing itself. When I tested out the blue cartridge, I saw that Select button was also hectically being pressed, alongside the up button and I think that is what is preventing me from going into the Gateway sub-menus and restoring my SysNAND, which I do have a backup of.

I am including a video that shows it concisely and hopefully it can be fixed. Apologies for the long text and if there's any extra information I could provide or if there's anything you guys could recommend trying, I would most definitely appreciate it.

For future reference, even on 8.1, I think it should be possible to downgrade just the system settings to have MSET back without having to downgrade the entire firmware back to 4.2

Not if he wants to launch Gateway through mset.

If you have a NAND dump, try restoring it by hardmodding your 3DS or asking someone to hardmod it.

GW through mset requires the whole firmware to be 4.x?

I guess I was considering hardware restore as the last resort but I am not that experienced with it and have not researched it a lot yet

If you can still access the gateway menu hold up on the downgrade option to restore a nand backup ......ooooops sorry.for my half hearted reading skills.....doesn't really sound like a nand issue imho, have you tried removing all accessories I.e, sd card, game cardfirst to rule out those

Thanks for the reply~
Holding up while trying to do the downgrade was one of the options I tried but it didn't work - made no difference~.
I removed everything as you mentioned and it seems like that made no change at all. Before I had the SD card inside but after removing it and removing the gateway card and then rebooting the system, the issue is still exactly the same unfortunately.

EDIT: I updated the Firmware to 7.1 by inserting the Professor Layton vs Ace Attorney genuine game in. The issue still persists - up button is as if it's being pressed down.

I can confirm that when I tried to play the original cartridge of Professor Layton vs Ace Attorney, the up and down buttons did not respond in the game (whereas the left and right ones did).

And last thing just to pretty much rule out a software issue would be to re-update to >4.x.......if the problem.still persists it's probably a hardware fault, is it possible any liquids have been spilt into it?, next step imo would be opening it up and checking for any dirt/signs of liquid ingress, clean it up, put it back together and see if it fixes it

Just made an edit on my reply since I saw your private message.

Also, I could definitely open up the console and see but I am quite sure that is not the problem. I could access the gateway submenus just fine and specifically after performing the "Format emuNAND" command, the issue started and I could no longer even access the gateway submenus.
I will definitely see if there is anything though.

I'm not sure if it's a viable option as I don't know what you have installed, but if you're able to access the system settings you can try to format your sysnand and see if that helps.

Bang the 3DS against a table. Not too hard, but not too softly either. It just might fix the buttons issue. If it doesn't work you might have to open it up.

Seriously, don't.

@.44 Magnum : Wow, that's something I didn't think about. I didn't have anything important so I just went ahead and formatted.
However, no luck. Still the same. As per gamesquest1's suggestion I will try to open it up today and see if there's anything that might be causing it on the hardware side.
I will take pictures just so somebody can assert me whether there's anything wrong or not.

And yeah, banging's a no-go.

Sorry to hear that, hopefully you'll be able to get it sorted out. Good luck!

 

[bowser]

But I was serious! Maybe I should've said "firmly tap" instead of "bang"

Opening it up can just cause further complications.

If the buttons work in one mode and don't work in another, I doubt it is a problem which a physical origin (water, dust). Am curious to find out what the problem is if you work it out though!

But OP said the buttons don't work even within a game. Leads me to believe it's a hardware issue.

It's most likely a hardware issue - if your NAND was corrupt it wouldn't even boot because it'd fail checksum verification.

Have you tried to calibrate the circle pad and touchscreen?
