Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
Because the thread here is just for help to patch a locked bin file and not to repair a corrupted dump...
For this I thought nobody can help here and decided to open a new thread to include both possible problems...Comment

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
Hi,
I'm new here and just getting my feet wet. I noticed that the instructions imply that the eprom be soldered to the MB. Is this absolutely necessary? I had a locked mb but I unfortunately broke a lead off of the chip removing it. No problem, I just desoldered the epprom from another MB from exactly the same model the as my locked patient a Yoga X1 1st gen. However, this unit had issues that CN easily be resolve and it was not locked. I de-soldered the chip (successfully) and was able to get a verified bin file using flashrom and diff. Can I just flash it using your utility or do I need to solder it to the receiving mb?
TIA,

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
@korhy
Starting with most 9th Generation ThinkPad models Lenovo introduced the Self-Healing bioses, then bios chip has a backup of bios (32MB), meaning that if you patch both copies, laptop won’t POST, won’t boot; if you patch second copy it will Self-Heal upon powering up the laptop and recover itself with unmodified bios; if you patch first bios copy I believe nothing will happen, it will work as normal booting from second bios copy.
What you need is a EC/KBC programmer (supposing Supervisor Password is SET), a programmer such as Vertyanov JIG or similar, but is advisable to first check what’s the EC/KBC chip part number to ensure programmer compatibility.Last edited by AAAC; 11-26-2021, 11:21 AM.Comment

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...
