It is surprising Quectel does not have public download links on their official website but after contacting Quectel tech support by email, they sent me a SharePoint download link for the latest modem firmware on the PinePhone, which is EG25GGBR07A08M2G_A0.303.A0.303 released on 2025-11-11.
I noticed that on new firmware, the release notes says we cannot downgrade below version EG25GGBR07A08M2G_30.200.30.200, "otherwise the module will not be able to work normally".
Did PinePhone users like @dchang0 (https://forum.pine64.org/showthread.php?...#pid123728) who upgraded to a version that don't support downgrades have any issue (e.g. with echo cancellation, call recording or GPS)? Would you recommend it and is there an advantage?
I also asked someone with the same firmware here:
