soldatdescieux Posted January 13, 2015 Share Posted January 13, 2015 Hi, and thanks for your time =) I'm attempting to flash the bios on my Y500 but am having an impossible time doing so. The first time, I had zero problems. This time, not for the life of me. See, my Y500 had to have her mainboard replaced. Upon booting, it was evident that this board has a much older bios than the one I used to have (Lenovo bios splash screen is completely different, older). When running the update installer from Lenovo's website, this is what happens: I'm not sure if I did it correctly, but I did manage to find all the files in my Temp folder and added the lines to the file which the error states, and still nothing. I even managed to find a v1.05 bios and the same thing, nothing. Any ideas? Thanks Quote Link to comment Share on other sites More sharing options...
thepharcyde Posted January 15, 2015 Share Posted January 15, 2015 Have you been in BIOS previously. There is an option Secure boot. Not sure what the default is but you have it enabled. Disable and retry. Quote Link to comment Share on other sites More sharing options...
soldatdescieux Posted January 15, 2015 Author Share Posted January 15, 2015 I just went back in there to look, but I do not have that option! The only thing I have is UEFI boot (which is enabled) and that is required for Windows to boot, of course. Quote Link to comment Share on other sites More sharing options...
kageurufu Posted January 16, 2015 Share Posted January 16, 2015 If you can find the .bin file it is trying to flash, try flashing from your DOS boot drive, as if you were flashing the modified version. I had to do this as well on my y510p, as I dont even have windows installed Quote Link to comment Share on other sites More sharing options...
soldatdescieux Posted January 18, 2015 Author Share Posted January 18, 2015 I tried flashing from a DOS USB boot stick. Specifically, I followed this guide: https://forums.lenovo.com/t5/Welcome-FAQs-Knowledge-Base/How-to-flash-InsydeH2O-EFI-under-DOS-enviroment/ta-p/278406And, of course, she didn't work. I was returned the following error: "Error: Not support AT-p information CL Registry:0x0."I'm at a loss. I hope there's something I'm missing or not doing correctly.

soldatdescieux Posted January 18, 2015 Author Share Posted January 18, 2015 Hi all, thank you for your help but I think I've done it. What a piece of work. Using the Insyde installer from Lenovo's website, I had to do the following: +replace bios filename (V2.04) with the V1.05 version I found, +add the EngineeringErrorDisable switch to bypass the IHISI and whatnot error I was having, +change two EC settings (as I was then prompted with an EC error after getting rid of the old one) She updated, and then updating from V1.05 to V2.04 was business as usual, though the computer did hang on an all-white screen after it was finished, forcing me to remove the battery. I had to change the support back from Legacy before windows would boot but anyway, it's done. Thanks again Quote Link to comment Share on other sites More sharing options...
