I'm from Uzbekistan. I had before issue with calling and network on EU. Then flashed china srock and no success, after that flashed miuitn v2.1 stable and the problem was gone
I've flashed MiuiTN v2.1 via fastboot with format data. It's worked :eek: Also changed VoLTE settings, it's not effecting to the network, everything working perfectly, no call drop and no signal issues are gone.
PS: Flashed MiuiTN over china rom.
Thanks for tutorial. Now I'm flashed V14.0.20.0.TMRCNXM modem image. It works but not stable. Maybe this tutorial will work for me.
Question: Will it work stable after these operations? Need I use latest firmwares of chinese and eu?
