I was leery too, I waited as long as for Big N to go from 11.1 to 11.3 with the firmware releases, and the only trouble I had was near the end when my SD was not recognized by the software to reinstall my system... very stressful, nothing worked... until I plugged my SD in my comp, transferred all the content into the original 4Gb SD I got with my N3DS (I was using a 16Gb Kingston) and it worked instantly and perfectly. If you wanna try, the only rules to not risk a brick is :
- do it calmly with no one to trouble you for the next 2 hours
- have spare SD of other manufacturers, if you haven't kept the original SD, sometimes Godmode9 is picky
- take your time, do what is said in the guide, and ONLY that
- don't hesitate to use the team's Discord channel to ask questions beforehand, or while you're doing it

I see that you have otherapp.bin, payload.bin and robpin.bin on the root of your SD, maybe the problem is there, try using only the latest version of the otherapp and remove the other 2 from your SD
