Hi!
Last month I bricked my 3ds, but I saw this new method

When I try to power it, nothing happens, no led, no blue screen, just nothing happens...
Can I try this method?
should I try to lauch 3ds with my acekard 2i (with previous installation)?

 

But could I use a ctrtransfer from the flashcard?

 

Either the 3DS's battery has run out, or your 3DS system has an MCU brick (which can happen when closing the lid on a New 3DS while on firmware older than 9.0, during the days of installing A9LH).

If you were unfortunate enough to cause an MCU brick, then NTRBootHax is not going to help you, since the system can't even power on. An MCU brick is when the System-on-Chip has been damaged by too high voltages. When that happens, there's nothing you can do to fix the 3DS system. But you can take off the NAND chip, so that the data can be extracted through a hard mod.

 

Yes, a CTRNAND image of the right type using Decrypt9 or GodMode9 would revive it.

 

okay, I had this happen to my n3DS XL sometime ago, and I was wondering using the NTRBoot will be a cheep and/or more continent way to unbricking my system or do I need to hardmod it?

 

this is the news I wanted to hear. I'll see if someone has all this and get right on it. I use my hacked n3DS to stream and i've been having kiniption fits not streaming and not playing Monster Hunter with the boys.

 

You just need one for your consoles region and the firmware you desire and use Decrypt9 to perform the transfer.

 

I just told you Lol. The one for your console/region as they must match. You can do the 9.2 transfer or you can google 3DOWN and use one of the public CTRNAND transfers there. It doesn't really matter which firmware you choose, unless you want a specific one.

 

No worries, good luck

 

software . . . the two types of brick you cant fix this way are hardware (ex you dropped the system and it never turned on again) and mcu . . . mcu is not common and only happens when homebrew incorrectly messes with the notification lights or closing the lid on a n3ds while it has o3ds firmware installed

in conclusion just try it it will likely work for you
if it does not then you already had a unrecoverable mcu brick so you cant possibly make it any worse . . . go for it
