Hacking Question Error code 2137-0040 (0x5089)

[The3rdknuckles]

So I tried downgrading from 8.0.1 to 5.1 and now when i turn on the switch i just get error code 2137-0040 (0x5089) after regular boot splash. Any idea how to fix this? I used choi to downgrade and I'm pretty sure I used exfat and not fat32.

Edit
I didn’t make a backup. I’ve never had this issue before.

Edit to my edit
I'm guessing that the issue was due to having big N have the newest update downloaded onto the console. Simply deleted and now I'm golden.

Restore a backup that you definitely made because it's a common sense.
And why the heck did you downgraded?

Why would you downgrade? I believe you have to go into maintenance mode to initialize the system

Doing what I might need to do in maintenance mode will delete all my stuff. Can I copy my Nintendo folder to a safe place then do that stuff then transfer it back and still have all my games?

Hi, did you solve it? I have the same error.

While you try booting into your cfw make sure you’re holding both volume up and down. When you’re in maintenance mode turn off your switch then try booting into cfw normally.
