Yes I have successfully converted couple of our 5070 units. You have to enter the BIOS “F2” and check the box “wipe the drive on next boot”. This will fully wipe the drive of the WES OS. Create a ThinOS bootable drive by using Dell’s USB Imaging Tool. Once you have a ThinOS Bootable, go into the commandsXml.xml file on the USB and find all the files with “FFFFFFFF” and replace them with “00000000”. Save the file and you should be ready to install your ThinOS successfuly.
