Without the FIRMs, it cannot boot up your system. You'll need to fetch the following at minimum, and put it at `/corbenik/firmware/native`:
Old 3DS (Native FIRM, 11.0):

Note that this is only a recommendation - you can supply near any valid firmware file for your console.
-You'll need the firmkey for it as well unless you have decrypted your firmware, and it should be placed at `/corbenik/keys/native.key`. I can't tell you how to get it obviously, but a good place to start may be an older version of Plailect's guide when it still had a section on Cakes.
+You'll need the firmkey for it as well unless you have decrypted your firmware, and it should be placed at `/corbenik/keys/native.key`. I can't tell you where to get it obviously, but there are a few ways to get valid firmware with/without a firmkey and not involving a download from a questionable place:
+
+ * Decrypt the CETK using D9 and extract the firmkey using D9's scripts
+ * Extract the encTitleKey using D9's scripts, and have D9 convert it
+ * Decrypt the firmware with D9 directly
+ * Boot another CFW, then reboot into Corbenik with a cetk for native at `/corbenik/keys/native.cetk`
You can also fetch the agb firm and twl firms to `/corbenik/firmware/agb` and `/corbenik/firmware/twl` respectively. If you don't have the firmkeys for these, you can fetch the cetk for each of them to `/corbenik/keys/agb.cetk` and `/corbenik/keys/twl.cetk`. Boot up the system, go to system settings, and it will extract the firm keys for them after rebooting.
