Have a look on xdaforums for your device, there will be guides. With the Samsung for example you have to enable bootloader flashing in existing rom developer options otherwise it will overwrite on a fresh boot. Gxda is a trove of info though

You need to unlock your bootloader.
-
Enable USB debugging in the developer options;
-
Reboot the phone in fastboot;
-
Connect the phone to your PC;
-
Run the commands bellow, line by line:
touch key.txt
fastboot oem get_unlock_key key.txt
fastboot reboot-bootloader
-
It should show a warning that the bootloader is unlocked;
-
Reboot in fastboot and install TWRP again.
Its been a while since i tinkered around but i think firstly you can try directly booting into twrp recovery and see if that's working.
For some phones overwriting the recovery straight away doesn't work they will just let you temporarily run custom recoveries.
If that's the case then you can figure out for your specific phone how to overwrite the stock recovery permanently.
Again i could be completely wrong but you can give this flow a try.
