I unplugged the battery cable and took my multimeter to see if the battery gives any voltage. The battery gives near 3.8v, so it seems to be fine...

Any more ideas???
3.8volts is low - a fully charged battery will read 4.2volts.

BUT:
The terminal voltage does not indicate the storage capacity.
I.E: It could be 4.2volts and have all the storage capacity of a hearing aid battery.

I don't recall if the K4 firmware requires an "Amazon battery" or not (some firmware's don't care).
So I can't say if your Kindle can be run on an external battery for testing or not.

I would re-connect the battery, check that the USB cable and connectors are in good condition, connect to wall charger, wait a few days, and
HOPE
it gets better.
