Error: Unkown pkg 1 version HOS version not supported

Hi, I'm trying to mod my Nintendo Switch, but I've encountered the same error three times now. First, I followed the guide from "switch.hacks.guide" using a cheap SD card I had purchased. After getting the error and searching online, I found that others suggested it might be due to using low-quality SD cards. I then bought a 256GB Nintendo-branded SD card and followed the guide again, but received the exact same error. Finally, I tried the "Nintendo Switch Hacking Guide For Complete Beginners" from this subreddit, but the same error message appeared.

MESSAGE ERROR

SERIAL

SD INFO

Any suggestions? Thank you in advance
