Notes:
0. If you break your system, you get to keep the pieces. This procedure comes with absolutely no warranty, use at your own risk.
1. check the device assigned to your SD card and adjust these instructions accordingly. If you restore to the wrong device, bad things WILL happen....VERY BAD! I cannot stress this enough!
2. the image create or SD restore take approx 5 minutes....patience is required!
3. the commands are for Linux, but will work from the CLI on Android or MacOS also.....watch your device names folks!
4. Windows can also restore an SD card from this image, there are many packages out there to do the job, I'm just not a Win guy. (if somebody would like to add to this post with Win instructions?)
SD card, image creation:
dd if=/dev/sdb of=N647_dd_factory.img bs=4M
gzip N647_dd_factory.img
SD card, restore from image:
gunzip N647_dd_factory.img.gz
dd if=N647_dd_factory.img of=/dev/sdb bs=4M
Comments/suggestions/corrections welcome!
