After wasting a few hours trying to reflash a K3 (usual symptoms: dead with the screen with the tree, orange light stays on forever, does not seem to recharge, etc.) I opened the back and tested the battery. Voltage which is down to 3.1-3.2v, charging does not seem to work, I am unsure why (bad battery or bad charging circuitry).
To proceed, I connected some AA batteries (2NiMh + 1 alkaline, giving around 3.9v) to the battery connector (see picture
Now I can reliably write the filesystem into the flash is progressing. I have not completed yet (in 45 minutes have done about 2/3 of the progress bar) but previously it would fail with an error within a minute or less.
Totally awesome! I am very happy to know that you can run a K3 without an amazon-approved battery. I just upped your karma to all 2's (adding an extra digit).
And I added your success report to the first post. It just keeps growing.
