a friend of mine has a (stock, bootloader-locked) Nexus 4 with a cracked display. It still shows the screen but touches doesn't work anymore. We want to backup the files, for example photos. But unfortunately "USB debugging" is disabled so that ADB doesn't work. We can still get into the recovery mode. But unlocking the bootloader would wipe all data. Since it already has Android 4.4.4 I think there is no workaround to unlock the bootloader without losing data.
Do you have any ideas on how we could backup the data from the phone?
