Hacking Help! My 3DS won't boot up

[Deleted member 426934]

Hello everyone,

I wanted to update with the Luma3DS to a newer version and then I pressed START (I think) to reboot the system... but it didn't.
Whenever I press the POWER button, the blue light lights up for one second and the shuts off immediately.
Please help me, how can I boot up my New Nintendo 3DS?
I installed the CFW from 3ds.guide, I think it's called boot9strap. Firmware version is 11.4.0-37E.
I don't have the nand.bin anymore because I've had troubles with my computer and everything has been deleted.

Please answer as soon as possible,
thanks.

Did you happen to update B9S before updating Luma3DS?
If you didn't update B9S, download and older version of Luma3DS and follow the guide to updating B9S. Then update Luma3DS to the latest.
