Can’t update from 17.0

I have trollstore 2 installed on 17.0 on an iPhone 12 and after seeing this whole vulnerability situation I’ve decided to update to iOS 26, however when I go to update it says my iPhone is up to date on iOS 17. I remember blocking updates using the terminal commands here https://github.com/Mikasa-san/Block-OTA but after using the command for removing the block it changed from cannot check for updates to your iPhone is up to date. Could someone help please?
