I want to give it minus star if possible. This ios software is a scam and not working. After download firmware, even the firmware detection is error where it shows 17 ios version one time and 16 version other time weird. But all things not working and I end up factory reset my phone using itunes (which obviously I don't want to do that's why I bought this scam program at the first place). The flaunt this money back guarantee but when the product not working they show feigning ignorance and want to give part refund? (Nonsense!)
