Thank you rastik.
Unfortunately it doesn't work on my KT. I've transferred e.g. the update_launcher_1.0_install.bin file to the /mnt/us folder (via sftp) and after that I executed your command via a ssh connection (XShell under Windows).
The "Update your Kindle" is still greyed out after these two steps.
It seems I must own a very special version of the KT because the screen orientation change (via the launcher menu) doesn't work here, too.
It's a rooted KT (sponsored, special offer version) with the latest 5.0.3 firmware.
