I am trying to help my friend out with his kindle, for some reason this thing will only boot if its plugged into the outlet. When its unhooked it just boot loops, and when I try and connect it to the computer it boot loops. It's stock and at this point I am not sure what I can even do.

If it will boot up fully then tell me if you unplug it does it shut of instantly? I'm wondering if the battery is bad, if this is a kindle 7" hd 2012 model (has the front facing camera) then you can always root it and reboot into fastboot and attempt a restore via kindle fire first aid or system restore tool. The 2013 has a bit of a different utility for the procedure and could require a fastboot cable depending on the os version. You can also tell what year the kindle is by its os version, 7.x.x = 2012 and 11.x.x = 2013, 8.x.x= 8.9 2012 hd, etc.

Ok it sounds like something could be up with the battery, a wall charger has more output than a pc so a kindle can't run off the low power of the pc, I'm guessing bad battery, but that could be a problem to check it if it doesn't have root already because I think the sensors that you can query the battery from in a terminal require root. The kindle's internal battery is replaceable, not too difficult to replace, I believe you need a star head screw driver and it's glued but other than that it's pretty simple.

Why would the battery cause a boot loop though?

You need a small Phillips screwdriver and a Torx T5, to be exact. You have to slide one of the speaker wires out of the way to be able to access one of the screws as well.

Well because the device is too low to stay on with a low power charger so the initial detection of power from plugging it in while off tells it to turn on but once it realizes how low the battery is it shuts off, then it repeats the process because it is plugged in still. Least that's my guess.

Okay I should have said that when it does power on it says the battery is on 55%

Interesting... still think it's a battery issue. If its reporting the wrong value because the battery is worn it would make sense.

Pull the battery and check the connector and see if it loose. I have seen just this situation after a tablet is dropped. It very well could be the actual battery too.
