This method uses already revoked certificates to install apps and employs a DNS to block Apple's detection of revoked certificates.
If you have used Scarlet in the past, there is a high chance that you have been blacklisted from these certificates, as they use the same ones. This means you will encounter errors even with the bypass-revoke DNS installed. The only way to use this method if blacklisted is to back up your device, then restore or reset it.
Using the DNS blocks certain Apple services from functioning, most notably the ability to use the Translation app and update your device. (Note: This only happens when using the Khomod DNS.)
