Hello, same issue for me, same model Redmi Note 12 Turbo China model, I am currently running MIUITN v2.2 which doesn't have this network issue.----------------------------------------------
Hi,
I also confirm this post.On the Redmi Note 12 Turbo Xiaomi EU rom CDMA band not working.In Chinese rom it works very well without network issues. My phone model is 23049RAD8C,when i installed Xiaomi EU rom model changed 23049PCD8G (Poco F5).
The xiaomi.eu rom seems to be based on a POCO F5 ROM and it's not suitable for RN12T.
