(Yes, it works with the newer devices also.) |
It stopped the boot loop. Stuck at the kindle tree. When plugged into computer, it cycles into "USB charger" mode (with backlight on), as detected by virtualbox usb settings. Then less than a second later it disappears (no USB device, backlight off), and repeats after a few seconds (or not). Inconsistent behavior. Earlier I got it to display various screens like ;611, and setings/device info. It rebooted on power adapter and got to 30% progress, but stalled when plugged into computer.
Different behavior depending on USB connection. The log provided by the OP looks like it reboots with no warning or error message. Serial port time, I think...
And when it did allow some settings menu access, plugging in USB cable did immediate reboot. But then just letting it sit awhile on the charger reboots eventually too...
And when I did get a screensaver up (by tapping the power button), it was ugly black and white, so there must be an eink waveform issue as well (though the eink wavefile analysis in the serial capture does not report an error). I wonder if the screen had been replaced at some point...
