iPhone type: iPhone 6S
iOS: 10.2.1
Jailbroken?: No. (That's what I'm trying to do :p)
Hey guys!
So, I'm trying to downgrade my iPhone 6S from iOS 10.2.1 to iOS 9.3.3 so I can jailbreak my phone. I followed a youtube tutorial (and checked another, and they were doing the same process), and downloaded the IPSW file for my iPhone 6S for iOS 9.3.3. I followed the steps (backing it up, opening iTunes, connecting to PC via USB cable), however when it went to sync, it gave me numerous errors, such as error -54 (https://support.apple.com/en-us/HT205597) and "This iPhone "NAME" cannot be synced. A duplicate file name was specified" (https://discussions.apple.com/thread/2520158?start=15&tstart=0). As you can see from the links in the brackets, I tried doing my research to try and solve these issues myself. For the error -54, the first solution was to just ignore it, so I thought, hm, let's try to ignore it. The duplicate file error was a little more pesky however, because when I tried following the steps, I got to around step 5 on jerrodsdad's response, however after I right clicked the iPhone and clicked properties, there was no "tools" button to press. I'm honestly super confused right now, so any help would be greatly appreciated!
Thanks.
