Backup gone wrong

[Silly John Fatty]

Hi people!

I restored a Backup on my 1st gen iPhone SE but something went wrong. Basically the phone is stuck at the Apple Logo when you start it, except the Logo goes on and off every few seconds. I can't even turn the phone off, even by pressing the Home + Top button. The iPhone also doesn't appear in iTunes.

Does anyone have an idea what I could do? I am completely stuck with it and see no exit.

Also, on a side note: I loaded a backup which was not the latest one (consciously, because there's something I need in that backup), and I might have updated iOS since I made that backup (not sure). So I may have loaded a backup made on an older version of iOS on a device with a now newer version of iOS.


Thanks for any help you've got for me!

PS: I've read that sometimes it has to do with the battery, but I had done a battery test (at Apple) recently, and my battery was like new.

iOS version shouldn't matter. Does it react on a force restart? Have you tried reinstalling iOS in DFU mode (data loss is not a question as I understand)?
