I removed the ribbons from the image, then i put them right back on, and then i realize that it was a mistake.
Also when i opened it, i got 2 black screens, blue LED and no sound, but then i tried to do the combination: L + R + Up + A
Now when i open my 3DS, its loading indefinitely, saying: Opening the HOME Menu... Do not turn off the power.
i think its a MCU brick.
Sorry for bad English
You broke the L and R ribbons? If yes, that's no problem, as the 3DS will work without it just fine, but you have to unplug them to not cause any potential issues by leaving a damaged ribbon plugged in.
I have a 3DS where they are broken, and unplugging them does absolutely nothing, you just won't be able to press L or R.
Oh, and if you see "Opening HOME Menu", then there is NO WAY the MCU could be bricked. You need MCU to turn the LCD panel, LCD backlight, and the CPU itself on, so if you see anything on the screen, then the MCU can't be broken.
However, it does sound like you probably either damaged, or didn't insert the SD Reader ribbon properly. Check if you have damaged it, or if you have inserted it incorrectly. I think I remember it a bit difficult to re-insert SD Reader, because it bends backwards on itself. It's also easy to damage it, because if you leave it dangling, the ribbon can get damaged.
Here's what to try:
- disconnect R and L ribbons completely
- disconnect the SD Reader ribbon (GENTLY! CirclePad is in the way! just disconnect it, don't try to move the ribbon out of the way!)
- remove any cartridge inserted into the 3DS (I have a DS cartridge which causes the 3DS OS to freeze on a black screen with no backlight!)
If you do that, and there is no other hardware damage, here is what should happen:
- if your 3DS is hacked, the blue light should come on, and turn off a second later (because SD with boot.firm is missing, this is normal)
- if your 3DS is not hacked, it should turn on in a few seconds (can take up to 13s sometimes), and you should see a white Home Menu, and most of your games missing (which are installed on SD, so don't freak out, it's normal)
If you're not that lucky to get one of the above, here's what else could be the problem:
- if Home Menu hangs, the WiFi chip might be improperly inserted, check if the connector and the pins are not damaged
- check if you have backlight: if you do, then it's probably a software problem... if not... well, need more info
EDIT: What 3DS do you have? If you have a new3DS or new3DSXL (should not affect new2DSXL), then a part of the 3DS OS (or the Home Menu) might crash if the cameras or their ribbons are damaged. This is because head tracking needs the cameras, and it needs them even if you turned the feature off.
