I accidentally deleted an entire folder of photos a few days ago on my Galaxy Note 4. My PC was also down because of a failed hard drive, so I was unable to back up my phone prior to this accident.
At that time, I didn't even know what "adb" meant; now I have droid explorer and Android SDK on my PC, and have worked out how to get my PC to detect my phone. Now I want to make an image of the internal storage; there are lots and lots of other threads about this, but none of them explain the commands people are using. I have been very careful not to use my phone for much of anything (it has been set to airplane mode to reduce the chances of things writing to the drive), but I can't keep that up for long.
Can somebody please explain what commands I need to use in order to get an image of the internal storage? I keep seeing information about "booting in recovery mode" and bootloaders but I have also seen people discussing dumps of internal storage without these things.
I just need to check if my photos are still there. It's pretty frustrating to figure this stuff out with very little knowledge of coding and zero knowledge of Android software, so if somebody could help me figure out what to do next and be thorough with explanations, that would be excellent.
