Recently I had changed the location of the iPhone's backup using command prompt with the code "mklink" It has surely changed the location of the backup, but after doing this, I am unable to find any backups in the iTunes.. It says your iPhone has never been backed up.. I need help regarding this.. Also I jailbroke my iPhone 5 running on iOS 8.1.2 using TaiG and the jailbreak was successful.. But after this, when I connected my iPhone to iTunes, it gave me an error "iTunes was unable to load data class information from Sync Services. Reconnect or try again later." I tried restarting my PC also many times but it didn't work.. Help is appreciated! Thanks!
