Cydia Impactor won't sideload When I try to sign/resign (sideload) H3lix-RC5.ipa (iPhone 5C w/ iOS 10.3.3 x32) or g0blin_rc2.ipa (iPhone 6S w/ iOS 10.3.3 x64) I get:

Error:

I have tried revoking all Xcode certificates and changing Info.plist's MinimumOSVersion value.

I originally revoked all certificates because I was getting You already have a current iOS Development certificate or a pending certificate request when attempting to sideload.

The iPhone 6S is semi-jailbroken, and sideloading g0blin is the only way to semi-jailbreak it, where with the iPhone 5C the only way of jailbreaking it is by sideloading H3lix
There’s bug in the Apple’s servers so you could use totally not spyware jailbreak. 

g0blin is not the only way to jailbreak at iOS 10.3.3. There are doubleH3lix which is developed by tihmstar (same person made H3lix too).

Also there is website called https://totally-not.spyware.lol/ can enable you to jailbreak without sideloading app.
