So ... I've done it ... and it's not good news at all.
With a surgical blade (a real surgical blade ... it's a surgery after all! :-P ), I've torn apart at the yellow tape wrapped around the controller on the Kindle's battery, cut at the foil, and did a little trick with an old metal paper binder and the piece of yellow tape that I removed from the old battery. I put some glue on each cable tip, then used the binder to pin the two cables down to the terminal (over the foil from the old battery, since it's conductive). It's detailed in the images below.
Then I plugged the controller + battery in. Suspiciously, the orange light lit up
immediately. In Geekmaster's case, it
took a while to do so.
But voilą! The screen blanked and showed the "charging empty battery" icon! It's basically a matter of time now, right?
No.
The screen flashed again, and the Kindle tree showed.
But no progress bar. It froze. Just like before the whole battery swap.
Unplugged and replugged the battery would throw the Kindle back to "charging empty battery" screen AND a "Lab126, Inc. Amazon Kindle 3/4/Paperwhite" device would show.
Each time, the time it spends at the "charging empty battery" screen would increase.
I forgot to tell you in my previous post that I asked the guy from the electronics shop to measure the voltage across the terminals of the dead battery
before the other guy opened it up.
It read 3.7 volts.
And so did the new battery, when I asked him to verify that it's charged before I paid for it.
Does it matter though?

* Another point is that the Kindle makes all sorts of very faint multi-pitched hisses as it turns on.
* It can go to USB downloader mode, and imx_usb runs, but the Kindle won't leave USB downloader mode, nor would it accept any more imx_usb commands (would freeze at "Interface 0 claimed").
* And, with the new battery, it does turn on using its own power without being plugged in, but it still gets stuck at the tree.
* With the old battery, it used to boot once or twice in a looooong time. The last time it did turn on was two days ago. But not a single time since the battery replacement. Doesn't that rule out "sudden eMMC death"?
I'm literally freaking out by now. What should I do?
It just seems not to be the battery.
But if that's the case, why the hell did it freeze at 75%, and jump down to 37% on rebooting that first time it ever froze? Isn't that indicative of a dead battery? And why did freezing it caused the charge to drop from 100% to 0%? Isn't that even more of an indication?
But on the other hand,
this.
What can you make out from all that mess?
