here file unlocked

Hello

A while back I requested an unlock for my bios but I flashed the unlocked file the laptop showed no signs of life other than an orange light that would stay on so long as the power button was pressed, other than that no signs of life. If I flashed the locked bios back then the laptop would boot but still be locked obviously. I was told that the unlock file was correct and to check my soldering, which I did and the soldering was fine as I was able to rewrite the original bios back fine and read it again. I have tried every guide on here to the best of my ability with no results, even going so far as ordering a new blank chip in case I had somehow damaged the old one and its the same issue.

Would someone please be willing to take a second look at the dumps and see if there is something keeping the unlocked file from powering on the laptop, or point me in the right direction to fix it myself?

Thank you

I have tried several times, even re-reading the chip after flashing to compare checksums of the unlocked file and what was just flashed and they match. If I flash the locked file it will power on to the password screen so I know that the chip is being written properly but something about the unlocked file keeps it from powering on. Is there a chance something else was corrupted on the EC chip when reflashed?Any other suggestions of things I can troubleshoot?
