Unable to Activate -An update is required to activate your iphone
I am trying to restore the Iphone using iTunes, but after we continue the set up, it says Unable to Activate - An update is required to activate your iphone. It just gives option to Shutdown. There is no other option available. Tried both recovery and DFU mode, both options says the information to activate the iphone cannot be obtained and the progress just stalls there. Any pointer on where to look the issue will be helpful, thanks!
