Here is a list of backup scripts for pulling a backup copy of firmware from Allwinner V3, V316, V5 and similar action cameras.
( If you want UNFEX-REFEX scripts for manipulating 'full_img.fex' files, then see this other link)
( https://glot.io/snippets/fcg8vyjyyv/raw/backup-scripts-links-list.txt )
( -- 'backup-scripts' should be 'unfex-refex-scripts' but it's a mistake, ignore it-- )

If a backup script does not work for you, then you could just install 'adb' software, connect
your Allwinner Vx camera to your computer via USB, and run the commands shown at the bottom
of this text. Scroll down to the end of this text file.

Video tutorial on YT to show you how to do the backup process - https://www.youtube.com/watch?v=QrhPxpFFMrc

Open and read the " readme.txt " file inside each .zip file that you download.

* In Windows, you must first DISABLE DRIVER SIGNATURE ENFORCEMENT *
