Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
Hello guys !
I've buy a second hand T480 .. like many peoples here the computer has a Supervisor Password set. And the seller ignore what could be the password.
I've read carefully the instructions and ordered a CH341A. Now i'm studying the answers on the forum after the main post.
I would like to clarify, if the Step 8 "Restore original BIOS" mean restore the binary dumped in Step 1 ?[ HOW TO USE THE PATCH ]
STEP 1: Flash and replace current BIOS with the generated patch file
STEP 2: Boot the machine
STEP 3: Press ENTER/F1/etc. to enter BIOS settings
STEP 4: Enter any character when asked for Supervisor Password
STEP 5: Press enter when it shows Hardware ID
STEP 6: Press space bar 2x when asked
STEP 7: Turn off machine
STEP 8: Restore original BIOS
STEP 9: Reset BIOS settings to factory default
Thank's you !Comment

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
Yes, it is referring to the dump created in Step 1.
As a precautionary move, create AT LEAST 2 GOOD IDENTICAL DUMPS.. you can use Beyond Compare software to open 2 dumps side-by-side for comparison that is what i used aside from HxD. Any small differences in the file is highlighted right away..
This is crucial because there are others who unfortunately had problems in restoring the laptop to its working state after a failed patch despite using the dump they made in Step 1.Comment

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
Thank's you for the precision, yes i have well undertood the important place take that dump, i will do at least 3 to be safe and check them carrefully !
I've done the 3.3v mod on my CH341A received this morning.
A did some test with flashrom on my spare hackintosh but got some errors, look due to the software ecosystem, so i will retry from ubuntu on liveusb..
So i booted on a LiveUSB of Ubuntu 22 and installed Flashrom 1.2 from repo.➜ ~ flashrom -p ch341a_spi -r test.img
flashrom v1.2 on Darwin 19.6.0 (x86_64)
flashrom is free software, get the source code at https://flashrom.org
Calibrating delay loop... OK.
Couldn't open device 1a86:5512.
Error: Programmer initialization failed.
the CH341A is well recognized in the output of lsusb.
but i got this result when i type this command :
flashrom -p ch341a_spi -r test.img
Also sometime the CH341A does not appear in lsusb output when clamped to the BIOS chip.cb_in: error: LIBUSB_TRANSFER_TIMED_OUT
ch341a_spi_spi_send_command: Failed to write 37 bytes
cb_out: error: LIBUSB_TRANSFER_TIMED_OUT
Does someone knew why ?Last edited by HiddenTTY; 08-30-2022, 06:40 AM.Comment

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
I'm not sure if anyone is following this Thread. But I'm stuck like many. The autopatcher isn't working on my computer. It starts then crashes. I've attached my bios dump for a P53s. If someone could patch i would be very greatful.Last edited by SMDFlea; 03-25-2023, 11:57 AM.Comment

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
You are stuck like many for the exact same reason - failed to read the dump properly.
But doesnt matter too much because autopatcher is unable to unlock P53s anyway. You need svod3, rt809 or vertyanov to read/write MEC chip instead.Comment

I had similar result but a patched bin is created anyway.

Hi, my laptop wont boot at all
With original bios no POST, only LED lights
With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
Some issues
A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
B- If updated from 500LN version 203 to 300, the battery stops being recognized
Things I tried
1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble... -
Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.
Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,... -
Hello,
I have a Lenovo Thinkbook 15 G2 ITL i5 Laptop (serial number: MP2BFZEF) that when I turn it on, the led on the power button lights up for 5 seconds, then goes out. There's no display and nothing happens.
So I thought it was a Bios problem.
I found 3 bios chips on the board, which I read with a bios programmer: two XMC model bios chips and a Winbond model bios chip. Each XMC model bios chip has two partitions named XM25QH128A [3.3V] and XT25F128A [3.3V]. And the Winbond model bios chip has three partitions named W25Q80BL 3.3V, W25Q80xV 3.3V and W25Q80DV 3.3V.... -
Hi everyone,
I have been doing hardware repair as a hobby for some years now and recently decided to learn about repairing laptops as a fun challenge.
I managed to get my hands on a "HP Pavilion Gaming 15-ec2523nd" notebook that only shows a white power LED and doesnt respond to anything.
After initial testing I concluded the bios seems to be corrupted since all voltages are normal and there are no shorts. HP has a feature for a bios restore from USB with winkey+B for this model. This did not work.
I have desoldered the bios chip (GigaDevice...
