    Hi, we have a load of Wyse 5070 and want to see if we can convert them to ThinOS as they are going to be cloud-managed soon – Does anyone have any experience of this can we just image them via a USB tool to a ThinOS build from the same model version???

    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.

    I more or less the same question / issue. I have some 5070 with Windows 10 IOT, and I want to change them to ThinOS 9.


    I went in the BIOS and performed a fill wipe of the harddisk.


    After this I created a merlin boot with the Dell’s USB Image Tool, but for some reason, the Thin Client will not boot from the USB Stick. I have tried several USB Sticks, different USB ports, OS_Merlin_v9.0.4024_5070, OS_Merlin_v8.6_710_WTOS_5070_16GB_EN and WIE10_LTSC_2019_UNIFIED_January2022.


    note: I did not change all the FFFFFFFF to 00000000 on all sticks.  But i’m not sure if this solves the issue.

    But non of the USB Sticks even boot, but they are seen by the BIOS.


    If i use the same USB Sticks in a non wiped disk, i get a different boot menu. What i also can’t explain. I could not find a lot of information about this type of boot menu.


    Does anyone have an idea how to fix it?

    Converting 5070 WES/Thin Linux/Ubuntu devices to ThinOS you will need the following:

    • USB tool 3.5
    • Download the 5070 2205 merlin image
    • Now, here is where you have to pay to play. ThinOS is looking for a BIOS security key, so you have to edit the commmandxml.xml file and search for FFFFFFFF and change it to 00000000.
    • Yes, this worked in the past. What’s new is you have to buy a ThinOS Activation License to use ThinOS.
    • After you flash the device, and it registers into WMS, it will ask for activation, no ThinOS Activation license no access.
    • Also if you have a device without PCoIP, this is how you can now get PCoIP functions.

    Hey Jim,

    thanks for the clarification!

    One thing though: Where/how can I get/order these “ThinOS Activation Licenses”?

    Thanks in advance!

    Ooookay, I also opened a support ticket with DELL.

    Short answer from DELL support: Conversion not possible, I’d have to buy a new device with ThinOS pre-installed. No word about ThinOS Activation Licenses.

    What gives?

    You can convert devices using the USBFT to ThinOS 2205. You will need to have WMS pro AND the new ThinOS activation license. To get a license contact dell directly for quote and order details.

    I would only change all the<mask>FFFFFFFF</mask> to <mask>00000000</mask>.
    Changing other fields / security keys could result in a bad conversion.
