Help/Support Cydia and system apps disappeared

[orej 6 iPhone 11 Pro Max 13]

Hello everybody,

Today I open cydia app and update Appsync from AppAddict repo.

I could not make the worst choice.

Now I don't have Cydia app, settings and all the system app disappeared (except calculator) and trying to find does not find them. 

I can't uninstall appsync and I can't use iPhone for call or send  imessage.

I have ios 10.2 and iPhone 6s Plus.

Can you give me some idea to restore without loosing the jailbreak?

Can I pass to iOS 11 and come back to iOS 10.2? I have shsh2 file saved.

I'm unsure why this happened but people always seem to get boot loops and stuff from installing the incorrect AppSync or something.

If you have the iOS 10.2 blobs try using them. I'm unsure if you can go from iOS 11 > iOS 10 with blobs though.

Boot into safe mode and remove AppSync
