IT WORKED!
I can't ever, ever thank you enough!

I basically stuck it in a fridge for just half an hour (I couldn't find a microfiber towel around me, so I wrapped it with a regular towel, but I noticed condensation on the screen, so I pulled it at half an hour).

It worked! The device sat there for about five seconds, then suddenly gave a couple of very soft hisses, like the ones you'd get with a damaged wall charger, except that it was coming out of the Kindle, not the charger, then the screen reflashed and displayed the "low battery" icon (not "Critical battery" with text, but a low battery icon with a picture of a USB cable underneath).

A minute or so, it powered up. The LCD was a bit slower (and I still feel that it is slow, but never mind), but it started charging from 1%.

I noticed that for some reason, KUAL and Collections Manager now feature the "cover" icons that I had seen in the decompiled version. Before that, it was only text covers. Weird, right?

An hour or so later, it froze again. I couldn't read the percentage (because it was plugged in, so the battery meter did not show the percentage), and a reboot caused the ominous freeze. I threw it in the freezer again. This time however, I wrapped it in soft cloth, and that did help (no moisture formed at all).

At first, it didn't boot, but just before I gave up, it worked. It resumed charging at 80% (not a good sign), but dunno, it did not freeze again as of the time of writing, albeit the LCD is a little slow (or is it?) (Edit: nope, seems to be my imagination)

I might edit the Kindle Touch Hacking page in the Wiki to add this notice. Do you think it's a good idea?

I still believe that the battery is toast though because it froze again at 80%. Do you agree? Is it worth it, in your opinion, to buy a battery that costs as much as a Kindle?

(EDIT 2: Froze again. I'm going to freeze it for eight hours -overnight-, then charge it again).

A couple of months ... maybe half a year now.

There was a member here that wanted to run a "current hazard conditions" report on DXG devices.
Snow hazards.
Alpine area ski resorts.
Outdoors.
In an area that **might** be above freezing in the middle of summer.

The devices where reported to be working quite well, even with their original battery.
I had to wonder about that one day, with a pile of Kindles showing "empty" battery icons looking at me.

And having a bit of electronics background (about 60 years of it)

And you call that "a bit" of background?

I wondered if the Amazon/Lab126 people had checked their designs at extremes of temperature.

Probably not, due to the Kindle being super-cheap and disposable. They might cut corners. They didn't even bother to lock the bootloader, even though it costs them nothing but a fuse. (I know, I'm going to keep quiet and not give them ideas )

Putting a Li-Ion battery in the fire while recharging it did not seem to be a good idea.

It is a good idea for a fireworks show though.

Which lead to the only choice, test the result of running the Kindles at freezing conditions.
Mostly just a matter of luck on my part.

No, not luck. Call it serendipity if you want, but not pure luck. It's not like you mistook the Kindle for a can of beer when you stowed it in that freezer

PS: Avoid "diags" when recharging if you can.

Noted ... but what about fastboot? Geekmaster once said that Kindles charge faster there. Do you agree?
