Redmi Note 11T 5G China doesn't have Signal after flashing with Global ROM

[NKhan_Gsm]

I received a Redmi Phone that according its setting its model was shown Redmi Note 11T 5G but its Logo Shown POCO

Customer Said he have given someone to Change its Language after that it doesn't have signal as I saw its back label it was China Model but when I checked its IMEI online according its IMEI it is Redmi Note 11E Pro that it is
a Qualcomm phone but the phone is MTK with MT6833P CPU so I am confused what was its Original Model as I searched tow models have Same CPU Redmi Note 11T 5G and POCO M4 Pro 5G so decided to flash the phone with Redmi Note 11T 5G China ROM same version after flash I the phone
shows NV Data Corrupted


So now how I can fix it with Global ROM and fix Signal problem ?


Here is the phone info with CMT2T when I recieved :
