orbi RBK50 firmware wont update 2.2.1.210

[natedowg2000]

i am trying to manually update my router and satalite to V2.2.1.210 i follow the instructions to a T, download the zip file and extract the contents then use the .img file but when i try to upload the file to the updating port (or wherever you select the file that contains the firmware) and says that i need to choose a file with the correct configuration. what am i doing wrong?

Solution: instal everyother firmware alternating between router and satallite until at desired version

If your initial FW version was a v1.x version, you only need to update to Version 2.0.0.74 on the satellite then router. Then apply v210 to the satelilte then router. 

You'll be good to go now though. 

Enjoy.
