I tried restarting mediaserverd, also tried reinstall rocketbootstrap. Still won't connect.
Same problem here. 11.3.1/ the 7 plus / jailbreak with Thor
I encounted same problem. iPhone7+ iOS13.0 jailbroken with checkra1n
“couldn't connect to mediaserved” It is not possible to correct that error. it seems to be a cydia update iPhone 8 Plus iOS 13.3 checkra1n
