I completely bricked my insyde Bios

Recommended Posts

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) :-/


Wish all of you an amazing day!


Tobias

EDIT: I recently found out that there is an other MXIC MX 25L1673E M2I-10G BIOS chip on the back side of the motherboard... Now I´ve totally no idea what to do...

EDIT2: Could this second BIOS Chip be for redundancy? Does that make sense?  ?

Yes, sometimes there are two. This is more common in desktops tho. If you are flashing/dumping with FPTW use the -BIOS to dump just the bios region. (fptw -d whatever.bin -BIOS). That is if you can get to windows. Otherwise, you’ll need a spi programmer with a SOIC8 chip clip to reflash the chip. You should be able to download the bios from the manufacture’s website. Just make sure you know what regions go where.

      Hello everyone! I am looking for an answer to a problem I cannot find a solution to ... I purchased an Amd wx 4150 MXM GPU module su e bay to upgrade my HP 8570W Mobile Workstation which is currently equipped with a Fire Pro M4000. Once the new GPU has been installed, the PC screen no longer turns on but works only with external monitors connected via the docking station. The same happens once the drivers are updated! If I put the old card back on, the integrated monitor starts working again ... How can I fix it?

      Bios Release Version – v2.0.0
       

       
      Updated or Modded Items:
      A11 UNLOCKED BIOS FOR m18Xr2 (UNLOCKED BY SVL7 AND FULL CREDIT GOES TO HIM FOR UNLOCKING!)
      SVL7 Also created the PRR2.EXE tool that allows you to flash the new bios by unlocking it.  (FULL CREDIT GOES TO HIM FOR THAT FILE PRR2.EXE)
       
      Here are ALL the things I've added, modded, and enhanced on this bios -
      I've added FULL LEGACY SUPPORT ON THIS BIOS with ONE or TWO CARDS (SLI).  You can FINALLY use Win 7 OS on your machine and run the 900 series GPU's! 
      This is a MAJOR breakthrough!
       
      LEGACY SUPPORT Confirmed.  Works with 900 series GPu's in single OR SLI formation Updated the Intel RST Legacy to v12.9.0.2006 (Supports TRIM in RAID0 - CONFIRMED) Updated Intel RST UEFI to v12.9.0.2006 (Supports TRIM in RAID0 - CONFIRMED) Updated the ONBOARD Video Card for the HD3xxx to v2171 - FROM v2132 Updated ONBOARD Video Card for the HD4xxx to v2171 - FROM v2132 Updated the LAN Firmware & PXE Boot from 2.0.5.9 to v2.0.6.6 ADDED NvMe Support for m18xr2 ADDED M.2 support for m18xr2 Updated CPU Microcode to v29 for the 2900 CPU's Updated CPU Microcode to v1c for the 3900 CPU's Updated GOP Driver for Intel Sandy Bridge CPU Updated GOP Driver for Intel Ivy Bridge CPU Updated MAIN GOP Policy module for the m18xR2 Eliminated some code that wasn't used in the m18xR2 Updated CSM Module (v2) Streamline some coding to make mod(s) run a little more efficiently (v2) Added FPARTS.TXT to rar file in v2. (I had forgot to add it in v1) v2.5 to be released shortly.  I've updated a few more modules that I didn't realize could be updated.  (It's only 3 modules, but it's still an update!)   It should be released in about a week.  Hope this helps ya'll!  
      Instructions to flash:
      Use a flash drive to create a boot disk into dos Unzip ALL files into the root of the flash drive (flash.bat, r2final.bin, fpt.exe, flash.bat, prr2.exe, fparts.txt,m18r2.hdr, m18r2.hdr.bin, readmefirst.txt) BOOT INTO DOS – Note, that when you set the bios to legacy in order to boot into dos, you MAY have to reinstall OS!  (Just be prepared to reinstall no matter what) Once you boot into dos, run the file flash.bat It will unlock your bios (THANKS TO SVL7’s BIOS UNLOCKING TOOL – ALL CREDIT TO HIM FOR THIS TOOL!) Let it flash… Reboot your pc, and enjoy the MASSIVE updates!  
      Be on the lookout as I do plan to release newer version with more updates in the future.  However, it wont be for at least a few weeks as I'm now working on legacy support for the m17xR4 and several other systems.  So please be patient!
       
      ENJOY!

      I have a iBuypower CZ-17 laptop, with a 2012 AMI BIOS that has E1762 as the version, which I believe means I have an MSI G70 motherboard. It has a 675MX GPU, but it's not useable in Windows 10 despite being "seen" in the device manager. I believe an updated, unlocked BIOS would fix my issue and have located the thread on this site with the BIOS I need.

      First of all, am I right? Will this fresh BIOS make my laptop that originally ran Windows 8 work with this old GPU?

      And second, I created this account, will wait 24 hours and made this post. Is that enough to allow me to download the file, or do I need to post elsewhere?

      Thanks!

      A part of my BIOS got corrupted that controls my laptops backlights. Other methods like the Gary Key fix did not work for me because I do not get any light up during post. i followed this guide  that says I need to extract and use the 6MB portion of an 8MB bios dump, only AFUWIN tells me "Error, ROM file size does not match existing BIOS size which is because my laptop BIOS size is only 5.87MB.  I don't need to flash the whole BIOS, I only need to flash a portion of it. 
       
      I've searched everywhere online for a dump of my laptop model but non exist that I know of.
