    Since boot9strap hijackes (not sure if I spelled that right)the bootrom to give us access to arm9 and arm11 will we be able to save us a hardmod from a bluescreen bootrom brick?since boot9strap starts milliseconds after pressing the power button will we be safe?

    AFAIK It doesn't prevent it, but you can Unbrick using B9S

    A shame, I hoped we could kiss hardmods goodbye if b9s could unbrick a blue screen brick :\

    Nope b9s doesn't bypass/hijack the bootrom, the bootrom still runs as normal but it is tricked into thinking specific signatures are legit, so if for example you screw up your nand ncsd header then you still get a blue screen

    But as mentioned above the ntrboothax/magnethax solution should bypass any type off brick short of hardware failiure

    BTW, if you uninstall B9S with a wrong step, you'll get a true blue-screen brick.

    The correct step is:
    1) Dump NAND.bin
    2) Use Hardmod B9S Tool to restore firm0firm1.bak into NAND.bin
    3) Restore modified NAND.bin

    DO NOT divide firm0firm1.bak into firm0 + firm1 and restore the separated files with GM9 or you'll be blue-screen bricked guaranteed.

    thanks for telling me but i don't see the point to uninstall it (for me because my 3ds is an old model so they won't accept repairs anyway)
