I'm still looking for a cure for my nonsense.

I put the kindle in fastboot mode, then execute:

fastboot setvar bootmode main

I get:

< waiting for device >

nothing happens.

Then I try:

fastboot -s G000K9XXXXXXX setvar bootmode main

I have tried with the serial number of the kindle, PCBSN, FSN from Device_info.txt generated by the diagnostic utility

fastboot is executed as root on mac os high sierra 10.13.2

I've tried with the forum binary and compiled it from here (Yifanlu Git)

Thanks again

Somewhere here, within the past few days, someone posted a fragment of the boot-up messages -
There, fastboot mode was mentioned as having mmc1 as the root device.
Customer Kindles do not have an mmc1 device, only the Amazon/Lab126 development boards have an mmc1 device.
