I’ve just been trying to recover an old iPhone 5s which is stuck in recovery (DFU) mode and whilst I haven’t yet had any luck getting beyond the Apple logo yet, I hope the following information may help others.
I installed iTunes 126.96.36.199 on my Windows 10 Professional machine using the Microsoft Store (which now appears to be the preferred way Apple is distributing it) and I connected it up, it saw the iPhone and downloaded the 2.9Gb firmware. I did then try a few other applications to try and fix the Apple iPhone but they needed the firmware – but where was it on my machine?
A few sites suggested checking
C:\Users\<Username>\AppData\Roaming\Apple Computer\iTunes – but that path was empty for me. However, using Windows 10’s resource monitor, I soon spotted the firmware file was at
C:\Users\<Username>\AppData\Local\Packages\AppleInc.iTunes_nzyj5cx40ttqa\LocalCache\Roaming\Apple Computer\iTunes\iPhone Software Updates\iPhone_4.0_64bit_12.4.7_16G192_Restore.ipsw
I suspect the name of the “Package” may differ between iTunes versions, but that should help guide you to the iPhone IPSW firmware file (which I could have also downloaded from
