good evening, does anyone by any chance have the bios of the BOSE speakers | SOUNDLINK COLOR II. The equipment is simply dead, I want to try a reprogramming of the chip before looking for an electronic fault. Thank you.

i have this bose soundlink with no charging nor any sign of life, so after digging they told me that the issues is mainly with the firmware which is corrupted, I looked everywhere for a dumb with no luck, can anyone help me out ?
PS: the chip is a 4mb chip, I found a dumb online but it has 16mb weirdly tho he had the same chip that I did but I don't know how he did it
thank you in advance. -
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

My dad gave me his bose soundlink color 2, claiming that the charging port was loose. I opened it up, plugged it in, probed around with a multimeter, and I can measure 5V all over the board. I wiggle the charging cable around, no change. The port looks fine: sturdy, clean contacts. I measure across the battery wires and I get 0V, so I assumed the battery was the problem. But then a few minutes later after I disconnected and re-connected the daughter board with the buttons, lights were flashing and I was reading 3.3V across the battery wires. The only logical explanation for this I could come up...12-12-2024, 03:20 PM -

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...
