Whats the model number, is it a Type 20GJ, 20GK

Re: Lenovo ThinkPad 13 gen 2 - BIOS Request

Type 20J1. I believe the bios for Thinkpad S2 will also work as it has the same motherboard. But cannot find that either.

Can you post your bios backup.The bios from lenovo is only a bios update,i can merge it with your bios.

Re: Lenovo ThinkPad 13 gen 2 - BIOS Request

Thanks but I try this already and it doesn't work. My bios is completely corrupt from the beginning due to a loose contact on the programmer while I was reading it, then I write another wrong one and is all gone now.

Re: Lenovo ThinkPad 13 gen 2 - BIOS Request

Try this bios,i merged 2 different bios together,i don`t think it will work but try it anyway. This bios is 16MB .

Re: Lenovo ThinkPad 13 gen 2 - BIOS Request

Thanks it works. But is asking for a password when I try to go to settings after the message that rtc time needs to be set and to press F1. It doesn't give no other boot options. Is that kind of password with a human head, I think is a supervisor password. Can this be removed from the bios or is embedded on the security chip?

Re: Lenovo ThinkPad 13 gen 2 - BIOS Request

I also get the message
0183: Bad CRC of Security Settings in EFI Variable
Any way I can bypass this on Hex Editor so the computer can boot?
I cannot go to F1 Settings because is asking for Supervisor password.
I believe these error messages are because the computer detects that is another bios installed.

Re: Lenovo ThinkPad 13 gen 2 - BIOS Request

I manage to get rid of there error messages by restarting many times the computer with RTC battery plugged and its main battery. It boots normal now but still have that password on bios settings. If I just press ENTER it goes to bios screen but won't allow me to do any changes. I think I need a mini UEFI bios boot tool to flash on the EEPROM chip to reset these settings. Do you have any of these mini bioses please? It will be a great help. And Thank You once again for providing the working main bios.

Re: Lenovo ThinkPad 13 gen 2 - BIOS Request

There must have been a password on the original bios,and i think it does indeed have a MEC1633L or similar chip,so flashing the bios and EC wouldn`t remove the password,if you had those dumps.

Re: Lenovo ThinkPad 13 gen 2 - BIOS Request

Does anyone yet play with the DXE Driver from allservice or anyone have this files please.

Re: Lenovo ThinkPad 13 gen 2 - BIOS Request

I hope someone will finally upload a DXE Driver so we can modify it to sort out these IBM's Passwords problem once for all.
Many Thanks in advance.

Hello, Can anyone tell me if Lenovo Autopatcher v0.2 works
for this model ? I have done a few readings with two different programmers
the files are identical, Lenovo Autopatcher is telling the file is corrupted.

And is the password on the main bios or EC.

Lenovo ThinkPad 13 Gen 2, Type 20J1, 20J2. Thanks.

Re: Lenovo ThinkPad 13 gen 2 - BIOS Request

Hello again, Related to my last post, Is there nothing that can be done?.
I have tried to reload the ME using fit.exe its not loading the bin file, there
is nothing more that I know I can do. Some help with this would be nice.
