832s reverting back to 4Kus DRW-2S81, poor TTG02 burn

I got a 4Kus DRW-2S81 flashed to an 832s. Is there anyway to flash it back to a 4kus so I can use the 4kus firmware. Im trying to burn TTG02 but can’t get a good burn (~200 PiF) with any firmware or strategy(mostly TYG02) . I’ve seen a person get good results with a 4kus USG2 firmware with TTG02 so im still hopeful but can’t flash back to it.

Is there any way to flash back/force flash or an equivalent liteon firmware available or any other Useful tips to burn this media.

I know there are shit batches going around but this is redicoulous.
