Poco f2 not roaming and roaming app settings crash


Mar 20, 2016
I updated Poco F2 from xiaomi.eu 12 to 13 a couple of months ago. Since that time the phone is unable to roam in other countries. I tried going to the roaming settings, but the settings app crashes. I could install 12 or try re-installing 13, but that means I lose all my data again. It takes me a lot of time to get all settings, apps, Magisk running the way I want it.

So I was wondering if anybody has an idea how to fix the roaming without installing the rom again.
