Note 8 error has occurred updating device software

I have a note 8 which I’ve tried flashing multiple times as when I received it it was stuck on “error has occurred updating device software” but to no avail. I’m either getting operation “successful 0-1 fail” or it’s stuck analysing. I’ve tried an-n950u and f version but haven’t used U1 versions. Would this change anything or is there no point as this device seems to outright refuse any sort of flashing. I am also unable to get any device info as it won’t let me leave the drive software screen so if anyone knows a way to grab the serial number or imei that would be awesome.
