@Siddhe5h

Can I have the region version of the WR902AC on the device bottom label? It seems this 0.9.1 0.2 v008a.0 Build 191209 Rel.57116n(5553) is not a generic version, and it could be a customized version for the local market, that means you cannot upgrade it to the generic firmware version for the EU hardware.

BTW, may I know which country are you based, and where did you purchase the device?
