DPO4104 firmware upgrade

I'm trying to upgrade a DPO4104 oscilloscope, the instructions in the website seem quite clear:<br> <br> 1. Download the latest firmware version in a suitable pendrive.<br> 2. Copy the *.img file in the topmost folder.<br> 3. Power off the oscilloscope and connect the pendrive.<br> 4. Power on and let it do the magic<br> <br> However the firmware process does not start. It powers on as no pendrive is connected. Ive also verified that the pendrive is compatible (by saving data from the oscilloscope).<br> <br> Any idea of what is going on?

A few things come to mind that might be the issue:<br> <br> If you are attempting to install the same or lower firmware version that is already on the scope it will skip the upgrade process.<br> 1. What firmware version is currently installed on the scope?<br> 2. What firmware version are you trying to install on the scope?<br> <br> It may also be firmware for a different scope.&#160; For example attempting to install firmware for the MDO4k on a DPO/MSO4k will also skip the upgraded process.&#160;&#160;<br> The release notes included with the firmware download will specify which scopes the firmware is compatible with.&#160;&#160;<br> <br> These are the two most common issues provided that the USB drive is functioning properly.&#160; Let me know if this helps.&#160;&#160;
