Hello,

i using the Poco F1 with 128G EU Version.

ROM: crDroidAndroid-9.0-20190305-beryllium-v5.1
Vendor Firmware: beryllium-9.2.15-9.0-vendor-firmware (also tried latest one. no luck)
TWRP: twrp-3.2.3-2-beryllium
GAPPS: open_gapps-arm64-9.0-nano-20190307
ROOT: Magisk-v18.1


My Issue:
Can't send SMS from SLOT 1 or 2. I'm getting Code 28 error. Also does WiFi Calling not work anymore.
My Plan includes Wifi Calling and SMS Flatrate. (German o2)

I had already change modem SUBID0 and SUBID1 to DT_GREECE. It worked with Lineageos then once i updated vendor firmware to latest non of them worked.

LTE Works fine, Calling also.


Please help me :(
