How to save images / videos from a Xiaomi Redmi 4X that keeps rebooting in every 30 seconds

Whew, it was a tough round but under 5 hours I figured out and finally managed how to save images and videos in this situation.

First I had to make some kind of connection between the phone and my PC. The best option for this was the platform-tools in the Android SDK. Then went into the shell with:

C:\platform-tools> adb shell

Next thing was to find out the path of the Dcim folder and list files in that folder:

ls /storage/emulated/0/Dcim/

there is a folder in it called Camera. After I got all the filenames in that folder I managed to copy them with the adb pull command: I copied all the filenames into an excel document and prepared them with the full command which was:

adb pull /storage/emulated/0/Dcim/Camera/video1.mp4 C:\media\

adb pull /storage/emulated/0/Dcim/Camera/video2.mp4 C:\media\

adb pull /storage/emulated/0/Dcim/Camera/video3.mp4 C:\media\

...

It contained 450 files. That is impossible to copy within 30 seconds, so I had to divide them into chunks. First I divided them into videos and pictures and copied 50 pictures at once per 30 seconds session. With videos, I could copy only 5-8 at once.

And one last but an important thing: on the phone the USB Debugging must be enabled (under the Developer options) in order to make use of the adb tool. And all the above mentioned only work when the phone is on!
