Error SU-42118-6 7.51 system software update

I’ve been trying to update the system 7.51 update but keep getting this same error code and I don’t even know what it means. I’ve looked everywhere and tried many different things but can’t get it to work.

Does your disc drive work?

Yeh kind of, I can get it to turn on but that’s it, I was able to download the 7.50 update but I can’t get the new 7.51 to update.

So you have an issue with the disc drive communication. Kind of = can get to turn on? Meaning its not taking discs? If so, communication issue with board and disc drive.

Is it more like to be an issue with the disk drive, motherboard or just the ribbon cables?

There’s an update check out it’s called reinstall it’s should be 1 gigabytes Data
