show me the bluescreen please...
For everything to work, you need to flash from under windows 8.1 or 7! On windows 10, it gives an error.
Thank you! This BIOS fixed broken wifi at my laptop
I love you.. Thanks a lot. After doing something years ago, yes something, I don't remember what I did, but I disabled my graphics card and after that I couldn't access my bios settings for years. After flashing this, now I can once again enable my graphics card. Not that it matters much, but I found peace. At first the display was dark, I panicked for a whole 3-4 minutes than forced shutdown by pressing the power button. And now it's all good, I mean better than ever. thanks again.
Bro how meny function are working
Thank you very much, DR.iTACHi, for the unlocked BIOS for the Lenovo Z570.
I wanted to ask: how can I change my Lenovo Serial Number, because your unlocked BIOS has changed my serial number.
Thanks in advance,
