Hello, 
I would like to update my router's firmware to the latest version but it doesn't work because my current firmware is too old. The minimum version for the update is ER706W-4G EU v2.0: 2.1.0 Build 20250810 Rel.77020, but I don't see this version on the official website. Can someone provide me a link for this firmware version? 
I only see these versions on the website: (I tried to update to 20250809 but it also rejected this version. I am on 20241202.)
