Do you have the stock recovery.img for your model?
Also, state the Android version

yes sir hovatek, the device runs on os 8.1. I don't have the original ROM, I've searched for it, haven't found it, sir. I have tried restarting the bootloader via adb, the device just restarted normally. do you have to flash twrp using your QFIL ... thank you sir hovatek for your help

what's the file format of the OTA firmware you downloaded?
have you tried extracting it using 7zip software?
