Hi,

Currently I got a report from a user that my app may crash when launch in iOS 7.0.4 iPhone 5s. I want to use my iPod touch 5 to test this issue. But when I try to downgrade my iPod touch 5 to 7.0.4. (DFU mode)

I found that I can't downgrade to old iOS now. Does anybody know how to downgrade the device?

Any idea is appricated.

Thanks,

Eric

ps: I got problem on my iOS 7.1 's simulator on iPhone 5s (Can't launch the simulator). And the app works fine in iPad, iPhone 5's simulator.

It's not possible. As you've discovered, iOS installations must be signed by Apple, and they only sign the latest release version that is compatible with the device. If you absolutely must test that version on hardware you have to go to the used market and find a device that has not been upgraded.
