Update Error

Hi guys, I really hope you can give me a hand here. I was rooted using method 3. Yesterday I unrooted the device. Today there were some OTA updates, so I downloaded them and wanted to install them. It was 58 if I'm not mistaken. The phone rebooted and started installing the updates and after few seconds a symbol of android popped up with an error message. After that the phone started and said that update wasn't installed and the origanal settings were returned. After that it said that there wen't new updates available. Factory reset didn't help either. Later a new update was available 59 I think, but the same thing happened... I really don't know what to do now.
I have ZF2 64Gb, WW version installed on it.
right now running 2.19.40.22
I'm really hoping for your help
