Redmi K50 Ultra stuck on fastboot

[kits004]

Hi good day everyone, I have Redmi K50 ultra (Diting) china version. Now I try to install or flash Diting global rom version then suddenly I accidentally click the FLASH_ALL_LOCK.bat is running I dont know what to do so I wait to finished it. Cause I worried about if I interrupt the processing im thinking it will be dead. So thats why. After finished, its only showing the recovery mode then with a RED note showed "THIS SYSTEM VERSION CANT BE INSTALLED IN THIS DEVICE". So what i deed is I click wipe data. then now im stuck in fastboot mode. Anyone can help me? only way is to unlock the bootloader again so i can flash again the original firmware which is CHINA VERSION DITING firmware.
