Is the backup save file is intact? If you can RCM then there is perhaps a little hope... Firstly you need to boot into RCM and use lockpick_rcm to get your keys, once you've done that go back to RCM again and mount the SD card (use TegraRCM GUI), once mounted go to the drive and in the switch...
Just some info for those who might want to look into this, I've played around with the ARM build quite a bit, you can actually test it yourself using qemu to create a virtual machine (keep in mind it's extremely slow and not usable but handy to test with).

Nope it's honestly super easy, you set your connection profile on the switch to the details found at lan-play.com and download their client, you then enable lan mode in the Pokemon options menu (L+R + Left stick) then you're able battle/trade etc with others.
FYI with Pokemon saves instead of editing and injecting, use lan-play and trade the Pokemon over. I use emunand, spawn what I want then trade to someone to hold for me on lan-play and then return to normal nand on lan-play and receive then in trade.
I bent pins 9 & 10 using a screwdriver, not had any issues at all. It still functions exactly how it should, charges fine, switch knows if it's attached or not. It's super handy for being able to enter RCM!
I am trying to hack Fire Emblem Warriors on my 2DS XL, I have been trying to get it to work, but I need some extra help figuring it out. I have HEX codes, and a possibly outdated plugin, but I dont know how to implement them
