Hi,
Does anyone have any idea how to fix all the issues I get now?
Starting from the beginning, a few weeks ago, with some previous update I had an issue when it stuck on verifying update. I updated it using iTunes and had that problem with 'An Update Is Required to Use Cellular Data on This iPhone'. It appeared that there was another update pending, I did it and everything was working well.
Today, I had similar issue with stuck on verifying update, so once again I did update it using iTunes. And the problem with 'An Update Is Required to Use Cellular Data on This iPhone' appeared once again. I tried to restore it from backup but it didn't help. I decided to reset to factory defaults and now it is totally messed up. I have no network signal, while setting up wifi connection I get 'Unable to activate - An update is required to activate your iPhone' and also in iTunes there is nothing except that screen with iPhone word in the middle and I can not click anything. I tried resetting, cleaning sim card, connecting to iTunes in recovery mode...
Any ideas??? I have still a warranty but I kind a need that phone :/
