I finally got it working after spending a few hours. Seems the solution was to extract the file from the stock firmware, ex. from here: https://miuirom.org/load?o=poco-x6-5g&v=14.0.6.0.TNRMIXM&l=en&t=Fastboot except the file was not called modem.img, but non-hlos.bin and after running the fastboot commandYes, I am trying to resolve issues with POCO X6 5G Global, with TWRP 3.7.1_12-Nebrassy and it does not list a partition called "modem". So I'm using fastboot method instead.
Despite trying several modem.img files mentioned in this thread, I get either no connection at all or limited to 3G/HSPA+. How is this possible, stock global ROM works fine with 5G, I re-installed it to test.
fastboot flash modem_a non-hlos.bin
fastboot reboot
The phone finally started to connect to 4G/LTE & 5G networks
What I find surprising is, xiaomi.eu is a custom ROM, so why couldn't this non-hlos.bin modem file from global firmware be included in the download instead of the useless (no reception) CN version?
Btw, I really appreciate all the hard work xiaomi.eu developers are doing, distributing high quality custom ROMs for free, to a point where it can be as easy as "Unlock bootloader, install the ROM and enjoy (with minor bugs)". But spending hours and hours trying to tackle this "no reception or only 3G reception" issue reminded me about how tinkering with custom Android ROMs or Linux installs can really be: for hobbyists or enthusiasts
