DRA v6

Similar to powdersn0w, DRA v6 refers to an exploit for iOS 6 allowing supported devices to restore and boot unsigned target iOS versions untethered. This is possible thanks to the work of synackuk and Pingzi610 on De-Rebus-Antiquis-v6.

In Legacy iOS Kit, DRA v6 is utilized with automatic creation of the custom firmware with easy setup and usage.

To use the DRA v6 feature, iOS 6 SHSH blobs are required, but since iOS 6 is signed for the supported devices, no existing blobs are required and the script will automatically save them for you.

Restoring back to iOS 6.1.6 or any iOS below iOS 9 requires performing the Clear NVRAM procedure in order for the device to boot. This can be done through: Useful Utilities -> Clear NVRAM

Requirements

• iPhone 4S or iPod touch 4

Supported target versions range from the earliest iOS version supported by the device up to:

• iOS 6.1.5 for iPod touch 4
• iOS 9.3.5 for iPhone 4S

Note

• Like powdersn0w, iOS 4 and 5 may not work on newer manufactured devices of iPod touch 4 and iPhone 4S respectively.
• There is an issue on some iPod touch 4 devices where the device does not boot after the restore. Not sure on what the cause or the fix is. discussion #1101
• There is an issue where the baseband may be broken after restoring to iOS 5 on the iPhone 4S. Workaround is to restore back to latest (6.0 with DRA v6 works too), dump the baseband, and enable the --disable-bbupdate flag on the next restore attempt.
• See more related notes in the powdersn0w wiki page.
