I completely bricked my insyde bios!
#1
Hello, my name is Tobias,

yesterday I tried to reflash this (Biosbackup.bin) modified bios BDMaster made for me a few years ago.
I used the windows interface to flash the bios but unfortunately the screen completely freezed and an error similar to  this one showed up: "Unable to flash bios, no permissions"...


I turned of the Laptop, removed the battery and tried restart it... But nothing... No fan, not even the power indicator LED on the power button turned on. Just a black screen.
After that I tried to reflash the bios by emergency mode, but that was unpossible because there is no power on the USB port.

The last option I´ve known was to use my CH341 EEPROM programmer with SOIC-8 Clip. I completely disassembled the laptop, connected the clip to the bios chip and reflashed the bios. Unfortunatelly it´s still not working, the laptop looks like being dead...


The Bios chip is this one: MXIC MX 25L1673E M2I-10G, SOIC-8, 16MBit SPI Flash.
It has a capacity of 2MB but the BIOS rom a capacity of 4MB. I did a lil bit of research and found out that on this 4MB ROM could be also be in additon stored the intel ME (management interface) with 2MB of storage...  How can I remove this from the BIOS rom? Otherwise I´ll never be able to reflash the Bios properly.


What am I doing wrong? ;(

Hopefully someone can give me a lil tip to revive my laptop (Acer V3-772g-747a161TBDWakk) Undecided


Wish all of you an amazing day!


Tobias



EDIT: I recently found out that there is a MXIC MX 25L3273E M2I-10G, SOIC-8, 32MBit SPI Flash BIOS chip on the back side of the motherboard... This one has a capacity of 4MB´s... Probably this is the one I need to reflash... I´ll update this as soon as I reflashed it...

EDIT2: Could this second (2MB) BIOS Chip be for redundancy? Does that make sense?  ?

EDIT3: The second one (2MB) is for the EC.

Hi
use SPI-programmer+SOIC8 clip and make damp (all chip)
