a friend's Galaxy S2 (GT-i9100) hangs in a boot loop after updating Android (she says). She asked my if i could rescue her photo's, contacts, etc...
Booting Phone to Download-Mode works, connecting then via USB Windows 8 device manager prints USB\DEVICE_DESCRIPTOR_FAILURE as Hardware-ID.
There's no custom ROM installed, the device is not rooted and there's no CWM installed.
In Download mode, there's no option to "apply update from external sd card".
Tried "wipe cache partition", still boot loop.
I've tried to use/install various drivers. But IMHO if there's no Hardware ID / Vendor ID in the Windows Device Manager, Windows can't decide which driver matches for this device. So, if there's no device driver loaded, there's no chance for Odin or adb?! Correct me if I'm wrong.
