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

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?

Hello, Xiaomi's that have firmware from China or CN can never be flashed with global ROM or another denomination, as you have put in the log, it is evergo, well you just have to go to the mifirm page and search for evergo and in the Chinese section or you can download the firmware and your Xiaomi will return to its original state or you can also use the cmt2 unlocktool software or any professional software by pressing read info or boot info to know which firmware was installed, greetings.
