Dump check please EMC 2875

Could someone please check this dump. I have dumped a few times, then changed $svs and SN but MacBook wont do anything after writing back either clean bin or original dumps.
I've downloaded the bin file from downloads section but theres a size difference and it wont write. Size of original is 8388608 and size of downloaded bin with serial no amendeded is 8388595?

Your dump was from Retina MacBookPro 13inch 2014 Core i5 2.6

Attached NewBios dump with your old bios serial number and ME cleaned.
Should be working fine for you Mac. Enjoy.

Appreciate that ghost. As I thought, dump wrote ok as did mine (same as usual) but I get nothing at all from MacBook after writing.
Verified write, but nothing from MacBook. Have done multiple MacBooks with the adapters and not had a problem like this so I’m assuming it’s something on the MacBook. Can still read, blank, write the chip no problem but no power from MacBook
