Well, but i’m talking about OA3 KEY ID value that is missing from the bios settings. And this is why i am talking about a tool so i can inject it manually...

Thanks guys, i figured out that i needed a SecureBoot disable in order to boot from the USB. Now using LVAR, i don't know how to enter the "OA3 KEY ID" as it says:

lvar86 /w /oa3keyid /b "0xXX 0xXX 0xXX" for example in binary, which i did and doesn't finally write it to bios, any suggestion please?

After using golden key and formatting the usb and install the files on it, restarting selecting usb to boot from, doesn’t do anything, it continues to windows I don’t know how it works

Hi,
I'm owing a:
Lenovo 300e 2nd Gen Windows Version
Model : 81M9
S/N : R911S76T
MTM : 81M9S03300
Board : BM5860_V1.3A​
Since i had a password reset and did a corrupted Bios Dump, the laptop after flashing it, doesn't have the right S/N and so on.
Is there a DMI Tool for this laptop so i can edit it manually, using the right system infos, and writing them to the bios file, any app, so i can do the things from the command prompt or a gui, please?
I'll be very grateful, and thank you!

Hello again,
I'm very gratefull as this BIOS file revived my laptop, as i've decided to desolder the chip, write the file on it, and solder it back! Everything was smooth, but on the setup screen, the BIOS shows (OA3 Key ID: Not defined) and "M829RRFF" as a S/N which is not mine. My S/N is:R911S76T
How please can i put back these infosin the DMI or Write them directly to the BIOS file. For info, my Windows key is the one on the dump file i've uploaded yesterday!...

Hello again,
Now on my desktop, i've just checked up my dumped bios bin, and found that it was corrupted dump by the CH341A, and that i had to connect the USB-C charging cable in order to make a good dump. Now, i don't have any other dump than that, would it be possible to rebuild the bios file so i can flash it back? Please, help me out!

I've attached the UEFITool Messages screenshot from my corrupted bios image dump, and a example of the same model from [URL="https://www.badcaps.net/forum/troubleshooting-hardware-devices-and-electronics-theory/troubleshooting-laptops-tablets-and-mobile-devices/bios-requests-only/91292-lenovo-300e-81m9-2nd-gen-bios-password"]another...

The chip reading was my fault, because, i did not plugged the USB-C charging port, so the chip can have enough voltage! Now i'm sure that the chip is properly flashed with the BIOS, and the reading is done and shows the exact data. Even when reading it many times, it shows same thing. But the screen stays always off, while the laptop is on!

I didn't powered it from before yesterday until after the flash, but what i did, before yesterday, is shorting two capacitors beside the CMOS Battery connector: 14 and C15. Will what i did is the cause of the BlackScreen?...

Hi, thank you for the help! Unfortunately, after i flashed the bios, the screen stays off while the laptop running! I don’t know what’s wrong, but had several attempts flashing this night with my only CH341A, which doesn’t recognize it perfectly! I was using it with the clip, for info...

Hi there, can anyone help me to clean bios password please, i'll be very grateful?
