I just received another package from a MobileRead member who read my post about wanting to trade for kindles to test on. It has a couple paperwhite models -- trying to see which serials/models, but they need to charge longer to stop rebooting, I think. Or I need to debrick one or more of them. The settings menu always reboots before displaying anything on one (and now it is stuck in a boot loop at the kindle tree screen, showing up on USB as "Lab126, Inc. USB Charger"). They need to charge overnight.

I need to package up my K5 I have been working on lately (well tested) and send it to him too, ASAP. Now I will be able to support 3 more kindle models!

One of the PW units has no response other than 4 blinks on the power LED after holding it for 8 seconds. Other than that, it does not turn off the LED even after holding the power button for a minute or more. The eink screen is stuck at about 90-percent boot progress, and never changes.

The other PW unit keeps rebooting, though it may sit at the desktop for several minutes. Rebooting sets backlight brightness near maximum. It remembers through spontaneous reboots that I turned on airplane mode and I turned off cover mode. We shall see how it behaves tomorrow. One bad thing -- tapping power goes to screensaver mode, and there is no grayscale, as though the eink waveform is hosed. More reason to learn how to create custom eink waveforms. It seems to be stabilizing now (though it just rebooted after I grabbed its info, and not responding to touchscreen or power button). The SN says it is a PW3 wifi, and other info:
The other one is still dead, other than the 4 blinks after 8 seconds of power button press.
Don't let it connect to the Internet or it will update to something other than 5.6.5 -
You need that to use the software jailbreak -
Although it sounds like this one needs a serial port.

You can find a thread by myself where I installed the adapter board inside of my PW-3 -
The usual USB cable plugs into the bottom - the serial/USB plugs into the top.

5.6.1.1 is what the PW-3 originally shipped with.
