Can't restore ipad; stuck in recovery mode
So i had a jailbroken ipad air on ios 7.X.X
I decided to un-jailbreak it and restore it to ios 9.X.X.
I waited for the update to download then when it started extracting software itunes came up with an error-
"Could not restore".
Then my ipad got stuck in an infinite recovery mode cycle.
That is whenever i would reboot it it would always come up in recovery mode.
When i tried to restore it in DFU mode all i would get was ERROR:3004.
I have literally tried everything.
Would be great if someone could help
Is this a good question?
