How to exit DFU mode iPad2?

Question

iPad

So they brought it in DFU mode. When updating the tablet via Wi-Fi, the firmware just hung and then rebooted, now it’s in eternal DFU mode and doesn’t want to exit either, not with the buttons that provide it and not through iTunes like restore the firmware there immediately an error (9) for this error Googled a lot and there’s nothing did not find a way. programs like TinyUmbrella RedSn0w don't help either. I tried a lot of things and it doesn't work. Here's the current just like it was puffed up to get him out of this state and then I decided to check what the problem was and rolled up 9 iOS and it hung on it and into reboot and again the recovery mode. So the question is how to get out of this mode?

Answer 1

1) Connect it to your computer in this mode
2) iTunes recognizes, click "Restore"
3) Wait until iTunes does all the work, and the iTunes icon with a wire appears on the screen
4) Enter DFU mode again yourself
5) Repeat step 1 and item 2
6) It seems to work

Answer 2

It should, but I did it 10 times through different Windows and it's always the same
