1. Battery trick.
2. 3ds CFW: Restoring functionality on a new SD card [post #2]
3. Depending what Luma3DS version you have, you may need to:
   
   • Updating B9S
   • , or A9LH to B9S
   • Hold (SELECT) when turning the 2DS on to check the Luma3DS version.

Your 2DS still giving you ARM9 error? Did you follow the steps about reformatting the card in FAT32 + 32 KB and running it through a full Write + Verify in H2testw?

Ah, this is fortunate news! Read what that error means here.

Here's what you'll need to do if you're using the CFW starter kit.

1. On card root, rename the Luma3DS v9.1 boot.firm to something like booty.firm, for lol.
2. Relocate and rename this,
   • from: sdmc:/luma/payloads/SafeB9SInstaller.firm
   • to: sdmc:/boot.firm
3. Reinsert the card into the o2DS. Your system should directly launch SafeB9SInstaller.
   
4. Punch the button combo in to update to boot9strap v1.3.
   • The boot9strap folder with *.firm and *.sha are included.
5. Delete the SafeB9SInstaller boot.firm. Rename booty.firm back to boot.firm.
6. Complete your CFW upgrade with Finalizing Setup.
   • Super important you backup the SysNAND *.bin image and do the Luma3DS CTRNAND parts.
   • Except for collecting files (again if using the CFW starter kit), don't skip any of the steps!
