    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)?

    You need another System that has Custom Firmware on it to create NTRboot Flash File to use on target system, the one that is bricked right now.

    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.

    What about a 3DS that had a wrong firmware flashed? Can I recover it using this method?

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

    That is great to hear! I've been away for a while, this is amazing news.

    I'll look for a tutorial on how to do it. Thanks!

    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?

    It should work for any software bricks (i.e. when the hardware isn't fucked), so yeah, probably. You just need a supported flashcart and a way to flash 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.
