Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
Does this solution work on Lenovo E595?Comment

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
@bojc
Most likely it does, as ThinkPad models ending with "5" have AMD processors, in which the bios firmware does not have the "Self-healing" bios protection.
So it should work for Lenovo ThinkPad E595, just make sure that you have a good bios firmware dump before starting.Comment

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
Hello all,
thanks for the tutorial and the software!
I will try to patch my T450 tomorrow.
However, I still have 2 questions.
1. do I also have to disconnect the internal battery (My Thinkpad has two batterys).
2. do I have to disconnect the CMOS battery or can I leave it on? (Want to flash the chip without unsoldering it).
Thank You!Comment

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
Ok thank you. But i have a Problem.
I have the Chip w25q128fv. If i take this dump the patcher gives me follworing error:
Using UEFIReplace to inject 2 DXE drivers...
[1/2] BootOption (GUID e0746c42-d3f9-4f8b-b211-1410957b9ff5)
t450_3.bin is corrupted or does not contain a valid dump.

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
Hello,
I am using the TL866 II Plus programmer with a SOP8 clip to read the BIOS chip of my Yoga 460. Although the Xgpro 10.75 software autodetects the BIOS chip correctly as MX25L12835F@SOP8 it stops reading with an ID error. The software returns "Check ID Error! Checked ID is:0x C0 00 08".
When I force it to ignore the ID error and read the chip anyway and try to read the dump in UEFITool it returns "FfsParser::parse: not a single Volume Top File is found, the image may be corrupted."
I guess, my TL866 II Plus programmer can't read the BIOS correctly. Can someone point me in the right direction to get a valid dump of my Y460 BIOS? Do I need a different programmer, software, or adapter for the clip? I hope I can use my TL866 II. I have attached a picture of my programmer setup.
Thank you in advance for your help.Attached FilesComment

Re: LENOVO BIOS AUTO-PATCHER for Supervisor Password Removal
Thank you very much! It seems I have to order it from China, as I can't find it at any shop here in the UK
. May I ask you for a better picture of the wiring between SPI-Driver and the clip?
Would it work with a CH341a programmer and my clip straight away?
Sorry for asking all these noob questions.
Thank you for your help.Last edited by Babyface_male; 02-01-2021, 03:35 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...
