About

iDowngrade tool can downgrade iPhone/iPad/iPod Touch firmware to any version without SHSH blobs, it allows iOS users to create signed firmwares that can be used to restore your iPhone/iPad/iPod Touch to any version that is being signed by apple in past. iDT generates unique firmware certificate keys  (similar to SHSH blobs) by fetching ECID, UDID, serial etc. from the device and sign firmware using these certificate keys, the signed firmware verification is done by redirecting original verification server to our TSS server to complete iTunes restore.

Supported devices

NOTE: Due to apple limitation you can only switch between iOS firmwares which are supported by your device. eg: If you have iPhone 5S you can only switch between the versions of iOS 7.x.x , 8.x.x , 9.x.x and not iOS 6 because A7 devices never had iOS 6.

iOS 6 downgrades are only supported by iPhone 5,4S,4 and 3GS.
