It started the upgrade when I entered the amazon credentials for registering the device. I canceled it and retried the twrp install and it worked.
So now I have twrp and nothing else. Then to instal the Hashcode's cm10.1 I used the adb sideload two times. First to install the rom-zip file and then to install the gapps-zip.
So now I have functional cm10.1 kfhd8.9". Thanks for your helponce again.
Mine updated, without signing into my account, when I first turned on WiFi and connected.
