Sup guys.
Recently bought used T480s. With locked BIOS, sadly.
After flashing (with ch341a) patched version of bios, laptop boots blank. Short lighting of keyboard, than screen is black and fan also stops and nothing happens. Then I flashed original bios, and everything back to normal. But I need access to bios settings to make some changes, so I have to find way remove this password.
Any help, please?

Serial Number: PC150B00
Machine Type-Model: 20L7002HUS
BIOS Version: N22ET76W 1.53

This won't work. The file you provided has exact hash as bios_PATCHED.bin that I get after using auto-patcher.
Maybe I need to follow "ME Firmware Cleaning Guide" to succeed?

T480s stores password in EC, cannot unlock with autopatcher, only this method works https://www.badcaps.net/forum/troubl...-ec-pwd-bypass

It's not working any more for T480s.
On latest BIOS FW it asks for password even after correct shorting. I don't know how, but they closed this glitch with software updates.
Also I have found several users, who succeed with autopatcher. For example.
Unfortunately, I'm not one of them. And I don't know what to do with my T480s.

YES I TRIDE MANY YOGA 370 AND SOME YOGA 370 NOT ACCPTING PATCH FILE.

try this file and follow steps from autopatcher

Greetings, will the LENOVO BIOS AUTO-PATCHER work on Lenovo Legion 5 15ith6h which is equipped with 2 bios chips (an 8 and a 16)? We ran it on both dumped bins, but it saw the files as corrupt. Thank you!

In my opinion the thread should be renamed to THINKPAD BIOS AUTO-PATCHER, meaning that it only works for ThinkPad models from 4th up to 8th Generation (e.g. T440-T480 and about a couple of newer models while transitioning to the Self-Healing BIOSes). So the autopatcher won't work on the Lenovo LEGION 5.
Open a new thread and upload your files so that someone takes a look at them.

On the Lenovo thinkpad W541 for some reason the 8mb dump seems to not work, is this normal?

Note that my 4mb bios got fried so they may be different dumps due to me having to flash a community bios in the replacement chip

thank's for making the process alot simpler @Knucklegrumble,
the tool you made is working to remove supervisor password on
Lenovo ThinkPad L13 with machine type 20R3 but, with some issues
that later i came across with my own solution & i wanna share
my solution that worked for me, because i've searched the net and
no one come with the solution.

after flashing patched bios to the chip i ignored message that said:
2204: System configuration data is invaid
and continuing the process that described on page 1, after re-flashed
original bios back to the chip the error message still exist, i thought
because i haven't done the "restore default" menu in bios and not attached
anything to the motherboard except screen, charger and usb keyboard

after restoring default in bios the error message still there and i still
ignored that, put back all together, set the date & clock and leave everything
on default value, exit the bios and before it boot to window the error 2204
emerge and halt the boot process, ask me to press ESC to continue and i did,
booted to window normaly and everything okay in windows, restart and error
2204 is halting again, asking to press ESC to continue (this time it get
my attention though). everytime the laptop turned on (cold boot or warm boot) always
halted by error 2204.

checked all serial in bios information it's all there, not invalid or missing.
i did all the steps on adding or editing DMI info using tool in
https://www.badcaps.net/forum/troubl...=5#post1622424
everytime i try to add using the tool it's always said "Data of the same device type is already in EEPROM"
searched for reference on error 2204 and found nothing related to my problem,
after intense nerf fighting i decide to take a risk that would brick this Thinkpad L13,
this is what i've done:

1. build bootable fdd using "Lenovo Gold Key U1 Tool", i followed instructions till creation using u1.exe
2. booted the fdd and choose top of the menu (forget to take picture)
3. press any key after choosing the top menu
4. i followed instruction coolshrimp here https://www.badcaps.net/forum/troubl...74#post1711774, i think the instruction from coolshrimp a bit different but, the main goal is the same, to empty stored data on eeprom & enter same data but with diferent "aproach" using the tool (i think), just remember to read the S/N first and take a picture of it, cause you'll need reenter those exactly the same as it was
5. after initializing eeprom chosen, the process could take 40-60 seconds so be patient and don't interupt
6. when done initializing it will ask to enter serial number, enter the "C0" section from the picture you take exactly the same
7. after that it will generate UUID & brand name, just choose "yes"
8. after done and pressing enter, it will go back to S/N utility. if not just try to explore one by one menu until you found it, in S/N utility choose "add S/N" and choose "B0" then enter serial from the picture you take exactly the same
9. choose exit from sub menu until main menu choose exit (shutdown)
10. done

sorry for the long story, hope it helps
