I updated my switch using ChoiDujour to 9.0.1. Noticed some problems with goldleaf installing as well as the cartridge slot so I attempted to downgrade to 8.1.0 again using ChoiDujour however on reboot it only brought me to a an error screen after the nintendo logo. I then attempted to use my nand restore that I created before updating to 9.0.1 (nand restore is on 8.1.0) with no luck, same error screen. I tried using memloader and deleting my saves as well as using a Fat32 card instead of an exFat which I had originally been using with no luck, same error screen. Any advice on what I can do? I have a full nand backup at 8.1.0 with all my keys. Thank you all for your time.
