LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal

[badcappo]

Working on old X380 Yoga Thinkpad with unknown SVP set, dumped 16.384 kb from Winbond W25Q128 chip, auto-patcher output says bin-file "is corrupted or does not contain a valid dump" - any hint? Thanks

Hi everyone! I'm having a problem trying to remove the password from my T480. I'm getting a weird tune on my thinkpad, and according to the Lenovo Diagnostics app, the error is 0285. Is there anything i can do? Already tried clearing TPM but nothing.
Thanks in advance!

Here is the original BIOS file and the patched one.

Hello everyone, I've gotten a hold of a Thinkpad W540, and unfortunately it is bios locked. really bummed out how the seller didn't tell me but here we are. I've made dumps of the 2 bios chips (25Q032, 25Q064. 4 mb and 8 mb respectively) and made sure to compare the files. I couldn't patch the 8mb dump as the auto patcher thought it was corrupted or not a correct dump. it did patch the 4 mb dump just fine. i've since then never touched the 8mb chip and just flashed the patched 4 mb dump to the 4mb chip with my CH341a. upon doing this, the laptop was essentially bricked and would not boot up. Powers on but the fans spin, no image and no beeping. I've tried to patch it and flash it a few times and removed the cmos, the external battery and the hard drive to no avail. The laptop works just fine with the stock bios, what am i doing wrong? Here are my dumps.

Okay, ... not worth my time writing to the nand directly, not even opening that old x270 ^^
I get it, if it is a near new machine, ok ... but if i can't use the software flash tools, i give up

I can finally report, on my X270 the patched UEFI file won't work. After reboot the flashing stops with error secure flash boot something error.

If anyone wonders how to force update: WinFlash64.exe -capload -file $0AR..._PATCHED.FL1

When did you see FL1 files being used? Everyone is talking about chip reading and programmer! It doesn't work like that.

there are several ways of accomplishing this, you can use a mini programmer to read the chip while on board or remove the chip and place it in the programmer and dumb the bios. obviously not all motherboards are compatible this way. this depends on the chip itself.

how to create a lenovo laptop bios dump file

victor555, "what do you mean get the images?"

[Victor555]

Please can you tell me what software to get the images from your bios chip ? XXX.bin

Have two questions if someone can assist.
For Lenovo T580
- Do you remove all batteries including CMOS before loading patch file.
- What files goes on the USB. Only the patch file or the folder files?

OK, how to update a BIOS on X270? All the update methods tell me i don't have to upgrade, i already got the latest BIOS.

r0iuj44w.exe -> extract, replace the FL1 file with the patched one. It is always the latest BIOS. Did downgrade a few BIOS versions, did try 4 or 5 older BIOS, always the same. If i use the Windows updater, i am always up to date as soon as i use the batched FL1 file. Also if i try the boot stick, it is the same message.

So is there a ways to force update or is the patch not working for X270 at all?

I'm over it, no more try and error

Regards

hi all i have a question I have a Lenovo ThinkCentre M720q

S/N S4HN3366

I want to change the BIOS startup logo because there was a different logo before, and I've tried using the BIOS and tools like CMD and PowerShell, but nothing worked. I thought I would flash the BIOS with a new one, but now another issue has arisen. I want to restore the old BIN file, but the SPI programmer isn't working. I get a message saying "buffer data SPI match." The first upload was successful, but after the verify, it failed with an oversize message. I press OK, and then I get the "buffer data SPI match" again. What am I doing wrong?

Hello
Can you help me with a Thinkpad E495 bios patch?
No matter what I do, whenever I run the auto patcher, I always get a black screen. I'm out of ideas.

man, thanku so much!!
i did what u posted in the 1st post and managed to bypass a bios password on a lenovo l480 using 8th gen intel cpu
the only thing i lacked was that python script, despite the fact i installed from the link provided in the tutorial , the cmd command told me it couldn't fint the python runtime
the i literally went to Microsoft store and got from there for free python and it WORKED
i flashed the patched rom , followed steps, and after that i re-flashed the original ROM and no password
