I tried to lock back my bootloader on my spark 4 and my device refused to turn on if I try to charge it, it doesn't come up and I used miracle box to flash my firmware which I previously dumped the device still doesn't turn on I tried to flash again with sp flash tool this time I did format + download. Still the same thing and now anytime I try to flash it will show an error code which means it needs an auth file have checked everywhere I can't find any auth file for spark 4 KC8. I'm thinking of downloading the original firmware from this forum and using aftersale flash tool to try again I don't know if this could work please I need help.

what's the build number of your kc8 device?
if you don't remember, use method 7 method @ https://www.hovatek.com/forum/thread-16005.html to find the build number (no need to backup again since you already have a previous backup)

if it matches the firmware build @ https://www.hovatek.com/forum/thread-30432.html , then you can download and flash using SWD tool (format all + download) @ https://www.hovatek.com/forum/thread-23709.html

This is my previous build id I think it was not this when I first got the phone it changed anytime I install an update on my device. But this was the build ID before the incidence. https://imgbbb.com/image/TDiQ62

which version of the tool did you use?
did you try using the latest version "download only" or "firmware upgrade"? also attach a screenshot of the error message, upload your screenshot to imgur.com
