Hello,
I've kept my PW4 on 5.12.4 ever since I've read the kind, capable folks here had found a jailbreak method, and having just now discovered that it's gone public, I'm trying my hand at jailbreaking.
After flashing the diags firmware, my PW4 is showing the following message:
[Text Status] Abnormal battery status.
I was only able to find another instance of this message, a post by @skstrobel
My PW4 still has a few months left on its warranty, so I'm guessing a replacement is a realistic possibility if indeed there is some problem.
Before I proceed, how can I tell whether there's anything wrong with Kindle's battery?
