Hardware DIY Brick Recovery?

[PaiiNSteven]

My 3ds is softbricked; it gets into the home menu and doesnt do anything else. I cant open any apps or anything (because i tried to cartridge update instead of regular update, dumbass me ._ .). Would I be able to modify some sd card file so that it boots into Decrypt9 or OTPHelper, so I could undo said softbrick? Thanks

Use the recovery menu

Do you have A9LH installed and a NAND back-up? If you do, you can just CtrBootManager9 to boot into Decrypt9 and recover from your NAND back up.

Following what jerrmy12 said, if you hold A, R, L and up on the d-pad when you turn it on, the 3ds will go into recovery mode and you can update it to the newest version.

I've tried that. Doesn't work either. :I
Edit; I was pressing the wrong buttons! Thank GOD I can update my 3DS before the 10.8 update. Thank you everyone so much!
