cant download dell 8fc8 patcherComment
-
Good morning. I have one question: for this method to work I understand I need a Bios "dump".
Are "dump" and "Backup" the same thing?
Do I need a chip programmer to create dumps and/or backups or is there any procedure to execute the dump/backup and upload the patched ones with no additional hardware and no need to open the laptop?
Thank you very much and apologies for the dummy questions, but I couldn't find the answers anywhere.
Thx,
P.Comment

Yes Paolo,
A dump is a file created after reading data from a chip with chip reader/writer (programmer).
A backup is a file created for data you don't want to lose....can be a dump from a chip or can be a zip file containing a dump from a chip.
...and yes 100% you need to open the laptop for this work.

I've hoped to find a tool to put a Dell BIOS back into service mode for at least a decade.
I have to say I think the last one the old Dell SVS Tag utility worked for was the D600.
Can I use this patcher on anything locked or not, regardless of the suffix?
If not, would changing those hex strings in the method described work on a wide range of current Dell boards (say 7th Gen CPU and newer?)
What would be absolutely fantastic is if I could make a generic or model-based flash utility to revert the BIOS to service mode like we could with the old TR4 BIOS back in the Latitude CP days.
I think Dell figured out we could turn a P166 CP into a PII 400 CpiA Clone with that BIOS and the proper CPU swap!
Those were the days.
Of course, I have a Latitude 5500 with a locked 8FC8 Bios, or I wouldn't be here.Comment

Hello everyone,
I’m currently working on a dead MSI GP75 Leopard (MS-17E71) motherboard (i7 CPU, NVIDIA GPU) with a no display/no backlight issue initially. After extensive investigation, I’m at a critical stage involving EC firmware, BIOS/ME region interaction, and possible deep corruption. I'm seeking advanced insight from anyone with experience in EC/BIOS sync issues or PCH-level behavior. Here’s a full breakdown:
🧩 Initial Issue- Board powers on (fans spin, keyboard lights up and can be adjusted, caps lock led lights), but no display or backlight
- External display (HDMI) shows

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 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....
