Downgrade an iPhone for testing purposes

I am wondering if it is possible to downgrade an iPhone to older versions of iOS even when the firmware is not signed by Apple.

I am a developer and I might need to install iOS6/7 on my iPhone, which currently has iOS8.

Is there a way to do that?

If anyone is still interested in this in 2017, you can save your SHSH2 blobs by following this guide & then using Prometheus from Tihmstar.

No, if you had an older device and saved the SHSH blobs when Apple were still signing the firmware then you would be able to.

I keep an old device for each major version of the OS from 4 upwards, and you get get them on ebay for quite cheap. iOS 6 is a very small percentage of the overall market now, so unless you are needing to support it for a specific reason it would be best to drop support.
