The video is showing wrong boot.img, you need to boot into fastboot and flash correct boot.img.
On my dell press and hold volume up and power, once you see dell icon release power and keep holding volume up til you get into fastboot mode, then flash correct boot.img.

Your first picture simply means tablet can't charge via computer, so charge via wall outlet, the reason you can't charge via computer is your boot.img is wrong or corrupt.
Once your tablet has charged via wall outlet for a few hours you need to get the tablet into fastboot mode, and replace the boot.img, you may need to replace the entire system, recovery, boot.img depends on what is corrupt, for now just replace boot.img.

It needs to charge first, the tablet should also charge while is recovery mode, provided recovery.img isn't corrupted as well.
Recovery mode on my tablet is hold volume down plus power, letting power go still holding volume down as soon as dell icon appears.
You can try on your tablet and see if you can get into recovery mode, if so you can charge via computer in recovery mode.

You are going to have to let tablet charge for a while, sounds like recovery is corrupt also, wont know for sure until tablet has charged, and you get into fastboot mode.
