How to restore original update sources for manifests?

[MikeSesketcharba]

I used

gci ~/scoop/apps/*/current/install.json | % { 
    (gc $_) -Replace '(?<=bucket":\s+")[^"]+',".SM" |Set-Content $_ }
scoop update
scoop update *

to change the update sources for all my apps. But when I tried to install new apps, I kept getting hash fail errors. I removed .SM and added extras again, and those apps that failed the hash errors now are getting installed without problems.

How can I restore the original update sources for the apps I had installed before? I want to restore scoop to the state it was before .SM because it's not working out for me.
