Hi, i am trying to run this mod on a Windows 8 Y410P BIOS which i have regrettably lost the UEFI/BIOS admin password for which of course i am chagrined over but at least I have my original proof of purchase. The official Lenovo solution is as you know to replace the motherboard at an additional cost. Not only do i feel Lenovo's solution is unfair but i do not have confidence in it. With this background out of the way... I have run the commands you have given above with their subsequent fixes for "Error 104" but i still get "Error 51" an attempt to read beyond flash memory. i have attached info.txt as you have requested of those who continue to observe errors. Please advise. info.txt
