Hi! I need help with an A1466 EMC 3178, original bios is damaged (also the Winbond chip), replaced it and writed it with this image, but It shows serial number "Not available", and I think ME region is not OK because it's really laggy, but, alteast, it stays on and everything works.
Need to write this SSN C1MWLA3QJ1WK and clean ME, please.
PS: it's a Winbond W25Q64.V chipComment

Dear All
First time to flash a prom in order to remove a firmware lock. Unfortunately ruined my bios with the clip of my programmer (ch341a). In the meantime I have learned that my programmer is not providing 3,3V which is needed for my chip "MX25L6473E". Have ordered a new one (Rev. 1.7) which will be delivered in about 2 weeks.
The only dump I got is the attached bin file. Any chance to rescue this?
Macbook Air 820-00165-A board from 2015.
Many thanks for your help!!!!!

Dear Peste
Many thanks for your quick reply. Bought the board on eBay. The only supporting information I can provide is as follows:
- 820-00165-A (printed on the board)
- C07705300NCGTQMDX (Board SN from sticker on board)
- MLB 1.6G HY 8G ON (from sticker on board)
- Firmware lock applied
- Board does not boot anymore
Any other information not available. Sorry. It is not much, but eventually enough for a first judgement.
Many thanks for your kind support.

Hello everybody!
To put you in context I recently replaced the battery from my HP Pavilion 15 bc400ns with a used one, everything was going good. The same day, I decided to update the BIOS, everything went good. The thing occurred after I let the battery drain iddling on Windows 11 for the second time to calibrate it that the screen did not turn on again, the computer was on but the screen did not turn, like it would not wake from hibernation. I decided to restart the computer but got no video.
The thing is that I had installed TeamViewer and could log into the computer... -
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...
