After I installed the xiaomi.eu rom to my Xiaomi mi 11 Ultra the 5G network disappeared, even though I was in an area with good coverage and had 5G before installing this xiaomi.eu rom. I've re-installed the original xiaomi rom and simply 5G disappeared from my smartphone even though I had the option to select the 5G network. Someone can help me?

I'm currently on weekly beta and never had any issues with 5g. In fact, I'm getting dual 5G and dual VoLTE. Speedtest is off the chart at 800mbps download.

activated prefer 5G

Finally it was not a ROM problem, was my Vodafone carrier problem, i was on roaming recently in other country and
i activate roaming on config, all was working perfectly.

from my point of view it must be a software problem.
on offical EEA rom it worked liked exepted bevore.

now on xiaomi.eu rom it dissapared.
5g is working in this region, i checked it with another mobile device......

any help would be great as i would already like to stay on eu rom :(

edit: prefer 5G is selectable, but a manually network scan only show´s 2G + 4G

could you try on SIM_AND_NETS/ADVANCED OPTIONS/ROAMING
switch on national roaming , and international roaming always...
after reboot. tell me if you have any change.

Any dev have a idea what i can do?
I talked to someone in a german community who uses a CN Device with Xiaomi.eu V13.0.10.0 Stable and 5G works on DUAL-SIM Cards.
I used a EU Device and 5G disappeared on both SIM Cards (Vodafone and Telekom)

Is there a log i can create or something?
Really need to solve this :/

Edit: i see in the xiaomi image there is a "modem.img" is this an untouched version from the official rom?

Thank you
