Banana Pi BPI-R4 + quectel rm551e-gl 2025

Hi,

I have a Banana Pi BPI-R4 paired with a Quectel RM551E-GL. I am looking for a firmware build that fully supports this setup and includes failover functionality.

I previously attempted to use Gfriendwrt, but the Quectel module did not work correctly.

Any help finding the right firmware would be appreciated.
