Product description
You should be able to use this cable along with the purple software (1nsane.dev) to read/write to your iPhone’s Nand chip without actually having to remove the chip. You should also be able to use this cable to unbind the wifi chip so that to you can replace the wifi chip without having to remove the nand chip. This cable DOES NOT put your phone into purple mode.

Please note that these cables are in used condition, but all have been tested fine.
