It does not matter if everything done via OS, as mentioned any software BIOS backup would be fine too. See my edits above.
Your CPU = 506E3, so either rom would be OK for that CPU, so microcode is not the reason 1.8 failed for you, it may have flashed in the wrong rom though, or anything could have happened (BIOS brick all the time, even stock)
I'm going to have to do some research and see which one it should be, in case the wrong one flashed in and that's what you dumped out. Do you have any images of the BIOS Main page, from ever/anytime?

No sir, I don't have :( I'll google to find something that looks alike : https://external-preview.redd.it/sra7j2e...31d06724c8a2d6e this is how it looked like of course with 1.8.0 at the bios version, other Cpu and other HDD, SSD. other service tag.

I need to see your exact system's BIOS image, or nothing. I'll sort it out, don't worry. That, or I'll make you two BIOS, one from each rom
Nothing for you to do until then, unless you know someone with this exact same system, if you do then ask them to send you an image of BIOS main page, and if they know how then ask them to dump BIOS region with AFU or FPT

Unfortunately I don't know anybody with the same system or with advanced tech knowdlege... I'm sorry for not being able to help you with more information, I searched on facebook groups of people that own Alienwares and I requested to join, I will ask there if anybody has the same model and can take some photos of the bios

R00 - BAP10022 >> 406E3, 506E3, 506E8, 906E9 << Supports Kaby Lake (7xxx) + Some Retail Kaby - Desktop + Mobile - NO ES CPU Support
R01 - BAP10033 >> 406E2, 406E3, 506E2, 506E3 << Supports Sky Lake only (6xxx) Desktop + Mobile & ES CPU's

It's OK, I'll get it sorted out Above notes for myself later tonight when I have more time. Is your CPU retail or ES, or do you not know for sure?

This should be : R01 - BAP10033 >> 406E2, 406E3, 506E2, 506E3 - supporting only Skylake

The cpu is i7 6700hq so it's skylake. You can't change cpu's without changing the whole motherboard on this laptop so it didn't had anything else before on it and it does not have anything else on it neither so there is no point in being compatible with anything else than Skylake if there is only 2 version, Skylake and Kabylake this is Skylake and it hasn't have to be Kabylake. I can read all sort of codes from the motherboard as I have it opened next to me if you please.

So I think it's only about Skylake as if you're not able to change the CPU without changing the whole motherboard neither there is a reson to be Kabylake compatile when I have the shitty version of 6700, the mobile one for laptops. This laptop is a laptop on which you can't change anything else except the ram, hdd, ssd, wlan chip and the battery. It has to be R01 - BAP10033

@BrickedAlien - We can't know that with 100% certainty though, but that is what the dump you sent has in it (although corrupted at microcodes, so that is why it's failing w/ CPU error)
You can change CPU on this board, any CPU with the ID's I mentioned above will work in this board (unless they've blacklisted certain ones, which is possible, but not very common)

Here, please test, clear CMOS before and after write, and be sure to verify the write too. Once in BIOS, load optimized, save and reboot back to BIOS, then make any changes you need.
If this fails, I will redo without your NVRAM (in case that is corrupted too), and then if that fails, I will redo with your NVRAM once more but with redone ME FW

I am currently not home but I will be in about 3-4 hours, It's really good news what you're saying regarding the cpu

I ain't home yet, when I'll write the bios do I have to put ram ssd and stuff back or just afterwards when checking if it boots? Does the cmos battery need to be disconected? Also, when clearing the cmos by shorting the pins under the ram do I have to disconect the Cmos battery? Stupid questions I know but wanna do it the right way

Ram must be there to boot to BIOS, SSD does not have to be there until you are ready to boot to the OS. CMOS battery should be there/in-place.
If there is no clear CMOS pins, don't worry about that step because removing CMOS battery does not always clear it anyway... It will be OK, just be sure you load optimal once you get into the BIOS.

whatever I did it didn't work, it did the same thing when pressing the power button

I am trying it again, read, verify, open your file, program, read and verify = chip and buffer same, hitting exit, removing cmos battery for 2 min, put it back, trying to power up and same behaviour although there is a slight change, half of the keyboard lights up now when I also press the power button in combination with any key then release both. It's interesting how this bricked "investment" can remember the last color it had selected for led's but can't post.

The latest update that was done succesfully via os and .exe was to 1.8.0 from 1.7.0 and it had in release notes something about Intel and improving security and such. Maybe the laptop contractited itself considering a security issue what I did and locking the cpu to prevent from stsrt. It also could be that I am doing something wrong, as an example after clicking open and selecting your file I don't feel like the program actually opened something. I realised now that is possible that I didn't run the programmer soft as an administrator.
I will go take a nap as I'm awake and alive on coffeine for over 30 hours, uni exams and essays and sh*t

Sorry for the douBle post jost doing it so not to annoy you via pm But for you to receive a notification.

THE LAPTOP IS BACK TO LIFE ! Thank you sir! The only Bad thing aBout it is that I screwed a long screw from the Back of the motherBoad through the keyBoard in the front and now the letter " B " is dead :)) But that's a small price to pay and I will remap B to another key or Buy a keyBoard.

Somehow I lost 5-10 fps in a game though and after 1920x1080 the screen resolution get distorted into not Being 16:9 But I don't think is related
Also somehow as soon as I Booted into windows I was prompted to receive a windows update...never did for a loot of months now.
I hope that you haven't secured a Back door into the laptop

Whoever gets here via google and got his alienware killed after a Bios update follow this chat on how to fix it, I am not sure if you actually need a custom Bios or if you can do it with the file got from unpacking the Bios.exe with 7zip.

@BrickedAlien - Awesome you got it! And you're welcome!
So, why do you think it was failing for you initially, just not good programmer write? Very sorry to hear about the screw and "B" Key!! , good thing is if you replace it's easy and now you already know how to tear down system.
I'm not sure since this is "Alienware" but generally laptop keyboards are fairly cheap, 10-12 for non-backlight and 15-20 or so for backlight ones. Hopefully you can find one cheap

What is this about resolutions?? Maybe you need to reinstall graphics driver? Sorry, not sure about windows updates, it may have to do with whatever BIOS or microcodes were in there (it may want to replace BIOS or load it's own microcodes etc)

Haha, no, I wouldn't even know what a backdoor is for a BIOS, let alone how to code one into the BIOS. I used stock BIOS volumes, and left your NVRAM and some padding files in place and replaced then only replaced several volumes from stock BIOS to the rebuilt one.
So, no, it's not really a "custom" BIOS, but you do have to know what you're doing to rebuild a BIOS and how to do that correctly with certain tools (not all can be directly replaced via tool, some need done via hex or BIOS will break).
You also have to know which things to leave in place or transfer into the new BIOS to keep your system specific info in there too, otherwise you'll loose your serial, asset/service tag, and possibly LAN MAC ID and Windows Activation etc.

Yes, the issue was with the way I was doing it and indeed if you load defaults in bios it asks you "Load optimized defaults?".

The Gpu issues were solved by pressing F7 and selecting to use discrete Nvidia Gpu always, so this way the dissaperead resolutions got back and the performance increased. Also in nvidia control panel the Display options dissaperead (resolution, brightness, contrast, scalling etc) and they apperead back after selecting with F7 the Nvidia gpu to always be used.
Overall I am happy with the way it works now but I will open it one of these days to change the thermal paste, also I need to buy a better cooling pad and an external monitor so I use it as a desktop.

Also I managed via the .exe from dell to install the previous version of bios, 1.7.0 as it seemed more stable and better somehow but the instalation looked quite weird, I thought for a second it's gonna die again.

Wow so glad to hear you got your system back alive! I believe that I'm in essentially the exact same situation as you are, with the same computer 15 R3.. I was updating to 1.8.0 and the update hung at updating ec 100%. Sometimes I get the 2-1 cpu failure code, sometimes it has normal lights but no screen and one in 20 or so attempts it will actually boot but the keyboard and touchpad don't work, and I see some signs of the ec not working properly, the fans run at 100% all the time and hwinfo doesn't have fan control anymore and doesn't show either fans rpm either.. Could you - would you please help me bring my laptop back to life too? For the last week I thought I toasted it and was already looking at the option of parting it out or selling it as a non working system - until I found this thread today, now I actually feel like there's a chance I didn't destroy the first real nice computer I've ever had! If you would be willing to help me I would be indescribably greatful.
