download MM for VNS-L21 (it doesn;t matter what CXX needs)
and the oem i will send to you will be REQUIRED for downgrading.
flash the OEM the one i will send to you...ONLY

Well , he should first extract the update.app from update.zip and then he is supposed to flash it.
And then the second zip , he need to remove a line from the second regional zip updater script and delete the update app from it later flash it .
Again extract the removed update.app and flash all files from the update.app using twrp by making a script.
Same process for the zip and it is done .

What did you do to the phone?

Hi I wanted to flash a rom to convert the version T to C (N920TUVS4DPH2_N920CXXU3BPJ5_CAM-WINMACX_V2.2.tar) everything went well except I lost the imei thank you

That the wrong thing u did.. before installing the other rom they might provided the custom bootloaders to install. like in Dr.ketan rom.
try instructions in dr.ketan by downloading some bootloader files specific to ur model. and install rom. Try ur luck....
If it didnt work try to install official stock firmware. This is what i Know let me know if u tried any thing et me know so that i can help if needed.

Download and flash this via Odin. If that doesn't work make sure you have the bootloader for T installed on your device.
