As we know, Cydia Impactor is a signing tool for working with iOS mobile devices which helps us install third-party apps (.ipa files) into our iOS devices. But Cydia Impactor is not working, and we don't know when it will work again.
We recently found that a new signing tool called AltSigner is convenient to use to sign IPA files. Therefore, we tested it with the jailbreak tool unc0ver and learned which version of unc0ver is more likely to be signed successfully.
Because there are many different versions of unc0ver, users need multiple tests to find a unc0ver that can be successfully signed and used.

Which Versions of unc0ver Easier to be Signing Successfully?

After our tests, the higher signing success rate is unc0ver 4.2.1 and unc0ver 4.2.0， while the signing success rate for unc0ver versions 4.3.1, 4.0.3, and 4.0.0 are relatively lower. If you failed to sign unc0ver with altsigner, you might as well try the two versions, 4.2.0 and 4.2.1.

Install signed IPA to iOS devices

It is worth mentioning that the difference between AltSigner and Cydia Impactor is that AltSigner only provides the signing function, but does not provide the installation function. So after signing, we need to use other tools for installation. Here it's recommended to try tongbu assistant or 3utools for IPA installation.
