Bios chip arrived, thank you very much having it soldered today. My brother identified the chip (cFeon F8075HCP) to replace with yours (Winbond 25Q64BVSLG) just wanted to confirm that they compatible? My brother said they are both SPI EEPROMs but wasn't 100% on the size difference and if it matters.

Bios chip has been soldered on and we have reassembled but still 7 beeps. One thing i noticed is the lights in the exhaust and trackpad have changed. Any ideas?

Oh my brother mentioned that close to the cFeon chip there was a Winbond 25X20BVNIG, the chip though was smaller. 2nd bios?

After I read through this entire thread I tried to revert my M17xR4 from the latest A12 bios.

Before I used Flashdrive method I simply reverted Bios to A08, think this might be importent.

Then I just followed the guide step by step and it worked flawless.

Just don't turn off your computer when it beeps and the fans are at full, it took 10-15 minutes while at that state before the pc restarted.

You need to turn off the your alienware first. Then with prepared USB in esata, you hold the end button while turning on the laptop.

I've try it but it don't work. Maybe it's because the last bios flash is A11 unlocked, no ? Must i use the same version to unbrick ?

Hi, i also have the official version A012 but i would like to install the unlocked A11, as per you stated, is not necessary to downgrade to A05? instead you went for A08

you had already bricked your bios or you wanted to install any unlocked BIOS version such as A11 or A10?

Regards,

Moises

sorry for reviving this thread.

 

i follow the process to blind flash my m17x r4 bios and failed. 

now the laptop does not power at all.

I have done some research about reprogramming the bios and ec chip.

 

just wondering if anybody here successfully got their m17x r4 working back after reprogram those two chip?

just successfully revive my m17x r4.

for those who bricked their laptop by following these guide:
https://www.techinferno.com/index.php?/forums/topic/1525-m17x-r4-bricked-bios-fix/
http://forum.notebookreview.com/threads/m17x-r4-bricked-bios-recovery-not-vbios.683080/

you guys still have another method to bring back the motherboard alive without replacing the motherboard.

the process in quite straight-forward but require additional hardware.
u can get from here
1. USB Programmer
2. SOIC Test Clip

You need to tear down your laptop to access the BIOS chip and EC chip.
Use THIS guide until step 26.
The location of chip can be found in this image 
https://ibb.co/mwFYFG

Use test clip to connect the chip with the USB Programmer.
the BIOS chip (at U48) can be connected easily but the EC Chip (at U36) need extra adjustment to connect all pins to the test clip. 

run the usb programmer software. read the content of both chip and save them as backup (its a good practice mention by t456)
after saving the original binaries, you can write the working binaries obtain in here: (thanks again t456)
M17x R4, bios and ec A11, A12 and A13.7z

choose filename containing bios for U48 chip and EC for U36 chip.
please verify the content of the chip with the loaded binary to make sure the content is the same.
in my case, the EC chip failed to store the working binary. thus i need to find new EC chip and replace it. 
you can get the chip name from the USB programmer software if you guys also face the same problem.

after successfully write new binaries to both chip, you can assemble back the laptop and turn it on. 

*i choose A11 bios and its working well. 

I think thats all for now. total cost for this method is less than 30 dollar. changing whole motherboard will cost around 270 dollar.

i posted this first in notebookreview forum and shared it here in case others wanna try this method.

      Hello, so recently I bought an used laptop, Alienware 17 R2 2015 to be exact. The seller told me that he couldn't install any drivers so I took it in hope that I can change that, and I've come to the conclusion that he tried to change the vbios and somehow bricked it. Does anyone have a backup bios for the GTX 980M (10DE 1617 - 1028 0688) or know where I can find one? I tried to look on techpowerup but can't find it. Any help would be much appreciated!
      Specs: CPU: i7-4720HQ GPU: GTX 980M RAM: 16GB DDR3-1600MHz SSD: some Intel 180GB ssd m.2 MOBO BIOS: version A20 MOBO: Alienware 17 R2 X04

      Hi Guys, may be someone could give me a good advice...
      The system:
      Alienware m17x R4 with 120hz panel form r3 (LG - LGD02C5)
      Bios Dell A15 (Also tried unlocked A11)
      Now installed GTX 860m 4gb (Kepler edition) works with no issue
      Bought GTX 970 6gb Aetina production Works under MS driver Does not show image on eDP internal screen right after installing Nvidia modded drivers All external ports ( HDMI, eDP VGA) works with no issues - tested on benchmarks the card itself works great The internal screen could blink several times depending on vBios flashed ( so the card is trying to fire it up) Internal screen is not recognized properly - Using Monitor asset manager i observed that: GTX 860 create two monitor entries 1) Realtime and 1) Registry GTX 970m creates two monitor entries 1)Registry and 2) Registry If I change the max Hz using CRU to 100 and Close/Open laptop screen it will show picture in 1024x768 resolution with no possibility to extend and it also see a "Virtual monitor" attached to real one ( extended)
       
      So the main issue is that INTERNAL Display is recognized AS 2 displays 1 connected to the internal laptop port and one into Display port:

      Hi there, 
       
      I'm planning to upgrade my gpu to the gtx 980 from my now knackered cooked 9 times hd7970, but looking at pictures and videos on the web I have a different 3 pipe heatsink to most it seems... 
       
      Others appear to have more copper present on the memory cooler section than mine. 
       
      My question is for anyone who has the same heatsink or knows of this one, have they been able to cool another gpu successfully?
