I did install cygwin and extract the files. I then copied the extracted files to the Minimal ADB and Fastboot folder.
I sent you a PM with my contact info as well.
I was on a laptop with only usb3 connections so now I am on a laptop with usb2 connections. I can connect the K1 to the laptop, run ADB and see the K1. But when I run amb reboot bootloader, the K1 just brings up the menu:
Continue
Fastboot Protocol
Recovery Mode
Reboot
Poewer off
It just sits there and does nothing. When I run "fastboot devices" the K1 is listed.
But when I run fastboot oem unlock I get a failed message.
At some point in this process I selected "unlock" on the K1. I believe that was in the "recovery options menu" that pulled up. The top reads:
[nvboot] (version UNDEF_BUILD)
[bootloader] (version UNDEF_BUILD)
device - unlocked
Continue
Fastboot Protocol
Recovery Mode
Reboot
Poewer off
