Can anyone post the steps for flashing firmware without doing a factory reset?

My S20+ Ultra has some sort of SW error and will not unlock the screen even entering the right password.

There is data pics/vids on this phone I don't want to lose and no other way to recover, I am hoping there is a way to recover the phone without deleting the date.

I have a copy of the firmware by using Bifrost, I would like to side load through an SD card, the resultant file after Bifrost ran is xxxxx.zip.enc4 do I rename this to update.zip copy to SD and boot into recovery mode and select Apply update from SD card?
