I bought a broken kindle from the classifieds, the guy I bought it from seemed clueless and genuine. He told me it was showing low battery, I think he said it wouldn't charge and he tried to use it and then got the error message.
What is it?
The serial number starts with G000K9 which I looked up, its a KT3 (Kindle Basic 2 (Black) 8th Generation).
The case identifies it as model SY69JL
The version code on the screen is 3330460020
What are the symptoms?
- White screen with Error Code 0 and Battery Invalid -22 message.
- Without wall charger power attached I get nothing from it at all, power button does nothing.
- With power attached to wall I get intermittent green flashing LED.
- With wall power when I press the power button it goes green, then amber then off.
I attached a serial port to it, I see the following, I connected power and pressed Enter repeatedly until it interrupted boot and I'm now at uBoot prompt.

I have the feeling either the battery is really dead and it needs a new one or the charging port is faulty. Any suggestions what I could do from here to check the device's health, the state of the battery and the state of the usb port?
I might be imaging in it, but I think the usb port feels a bit sort of loose inside it when the cable is in it, I am able to move the cable around a little and occasionally get a weak green light to briefly appear. With the case off the port seems secure on the board.
