New Update HyperOS 1.0.47.0 UNCCNXM killed my Mobile Internet connetion

[SSDHarry]

I just updated my Xiaomi 14 to stable HyperOS 1.0.47.0 UNCCNXM. But it broke the mobile internet connetion. I contacted my service provider and they checked all parameters, but nothing helped. I put my sim card in another mobile, and in that phone the mobile connection was immidiately active.

Now I have come to the conclusion that there must be something wrong with this new update. Because: (1) before the update from 1.0.45.0 tot 1.0.47.0 everything was fine, but after the update no mobile connection via the sim card possible, (b) the sim card is fine because it worked in another phone, and (3) all software related parameters are checked by my netwerkprovider and are fine.

Can somebody help me to restore my mobile connectivity?

It seems like you overwrote the modem fix. Flash global modem via fastboot.

Is the latest system the beta version of the Chinese version? Is it still the normal version? And is it Android 15?

It's the stable ROM.
Beta ROM with Android 15 would be OS1.1.4.0.VNCCNXM.BETA.
But xiaomi.eu haven't released it yet.
