    I have a bricked "new" 3DS XL and a fine old 3ds XL. When I power on 3DS, it shows blue screen of death bootrom error 00F800FF F8F8FFFF FFFFFFFF.

    From https://www.3dbrew.org/wiki/Bootloader#Error_Codes that mean "Both the firm0 and firm1 partitions are corrupt (failed signature checks)".

    I searched google and found some threads mention this error.

    https://gbatemp.net/threads/help-me-try-to-unbrick-this-3ds.490538/

    I conclude that it need to unbrick by flash backup nand which I don't have one or use Lazarus3DS method.

    I could access to godemode9 by flashcart + ntrboot.

    Lazarus3DS ( https://github.com/AnalogMan151/Lazarus3DS ) looks like only my choice but I have no donor new 3DS. I have only old 3DS (This one could be any help?) . Is there any available method to help to unbrick my new 3DS with this situation?

    Lazarus3DS is not necessary if all you need to fix are the FIRM0 and FIRM1 partitions. In fact, Lazarus3DS should be avoided if possible as it will permanently erase your console unique files. If your original nand files are still intact, try repairing the 3DS firmware as follow.

    ***

    You can reinstall boot9strap using the ntrboot method with either SafeB9SInstaller or even GodMode9.

    If ntrbooting to GodMode9, check that the firm0.bin and firm1.bin are present in [S:] SYSNAND VIRTUAL.

    To reinstall boot9strap,
    • GodMode9 → press (A) on boot9strap.firmFIRM image options...Install FIRMInstall to both

    If GodMode9 fails to install B9S by stating the following error,

    You will need to download secret_sector.bin at [3ds.hacks.guide] A9LH to B9S using a torrent client like Deluge or qBitorrent.

    1. GodMode9 v1.9.0 → press (Y) on secret_sector.bin to [CLIPBOARD].
      • If selection mistake occurred, press (SELECT) button to reset.
    2. [S:] SYSNAND VIRTUAL → press (A) on sector0x96.binInject data @offset| 00000000 | → <A> yes → button combo → <A> yes.
    3. Press (A) on sector0x96.binCalculate SHA-256.
      • 82F2730D2C2DA3F30165F987FDCCAC5CBAB24B4E5F65C981CD7BE6F438E6D9D3
      • This hash has to match or else you can't install boot9strap to FIRM0/1.
    Once sector0x96.bin is fixed, try again with reinstalling boot9strap to both FIRMs.

    No, I don't know. This unit is received from another.



    It looks very promise. I will try soon. Thank you. :)
