Ok thats at least i can do for you for helping me.

I did it and it restarts but shutsdown. I have to powerup by myself but it boots fine.

fptw.exe -greset - should cause a shutdown/reboot.

You are now using this BIOS I sent you correct? Fix-UPD-ME.bin. I will look at default settings vs fail safe and see if anything sticks out to me that would maybe be causing it to fail.
To rule out any BIOS edit error, maybe I should have used some other version of a tool used, or something like that, go ahead and flash the stock BIOS from Asus now (using standard Asus Method) and then clear CMOS, reboot and load optimized defaults again and see if same happens.
If it does still happen, then maybe they have some error in the stock BIOS on this version, that wasn't in previous version you were using. Or is this version now same you used before?

Yes im using the Fix-UPD-ME.bin

How do i flash the stock bios because its saying in bios flash tool that this version is same that you allready have and it wont flash it?

Thanks for confirming BIOS in use, I will check and see. On the flash, can you flash older version (one version previous)? If yes, do that and then reflash back to the new one. Otherwise I will have to look in BIOS for you to change this setting reflash same version.
What are you using to flash that tells you this, EZ Flash or AFU? If AFU, check if there is setting to allow same (Same for if using AI Suite too) For AFU try with /X and /CAF switch.
Also, if you see clear NVRAM option use that too, this could be caused by corrupted NVRAM section and clear CMOS now if you have not already, then try again see if same after loading defaults.

*Edit - Here, please test this version BIOS now, this has all stock BIOS region (without edits I previously made to allow you to fix the ME) Same ME is there, but you do not need to worry about that anyway.
Flash using >> FPTw.exe -bios -f ReStock.rom

Flash programming tools package for your setup is in this post #75 - Asus X550LB shutting down every 30min (5)

If you loose board details (Serial, UUID, LAN MAC ID etc we can put back later, I see LAN MAC ID is already invalid in the fix.ME BIOS anyway, is your LAN working?)

Ok tried flashing the ReStock.rom. I get this.

Error 280: Failed to disable write protection for the BIOS space

OK, we don't want to use programmer on that BIOS due to it only having stock empty NVRAM, but we could, just would cause more need to fix things later.
Which we may need to do later anyway, either by programming Fix-ME BIOS again, or me re-editing your board details back into a fully working BIOS once we solve this issue.
If you don't mind getting deeper into testing, here is how you get around that lock using my guide - [GUIDE] Grub Setup_Var Guide - Fix Intel FPT Error 368 - BIOS Lock Bit Set HSFS W/ Asus Z170 or Other Mod BIOS
You can start at step #6, because I've gathered the variables for you already, these are what you will change >> 0x74 and 0x75

Or here is new tool that does the same - [Tool Guide] AMI Setup - IFR Extractor AMISetupWriter

Or, did you ever test flashing older BIOS version again yet? If this model has USB Flashback that will allow it, even If EZ Flash will not. Then flash latest stock BIOS again if you get that accomplished

I dont think this has that USB Flashback function, i only found tutorials for newer desktop mainboards.

How do i create Bios backup? For that [Tool Guide] AMI Setup - IFR Extractor AMISetupWriter tutorial.

So is the conclusion that my original Bios dump is faulty?

I already have BIOS dumps from you. No, I don't think it's corrupt, at least not badly, maybe a few bytes here or there possibly. The ME region was messed up in your original BIOS, but rest was maybe OK somewhat.
My goal here was to get the parts I personally modified in the fixed-ME BIOS back to stock for you (changes that were not a part of Intel ME, but rather a few settings changed in the BIOS setup module from BIOS region) To see if these changes put back to stock, fixed the current shut down/optimized issue.
Method I gave above at #81 will let you flash BIOS region using FPT, from the stock BIOS rom file/ be sure to extract body from .cap BIOS with UEFITool, right click where it says "AMI Aptio Capsule" and choose extract body, that file is your stock BIOS.bin to use with FPT and method I mentioned at post #81.

I would not use BIOS Backup for that guide, sorry I have not read it in full since it does the same as my manual guide. You could, but that would only be putting back same non-stock BIOS you already have now (If used as source to write back to BIOS)
I checked the batch file and the guide, use the stock rom, extract from capsule as mentioned above, then use that with the rest of the guide.
Start at step #2, once you have the BIOS.rom, I gave you the two variables (Varoffset values) you need in post #81 anyway, so all you need to do is write to the setup_Var in Grub (the guide only shows unlocking one, you will do it twice with different variables)
Remember, we can always put all back with programmer, so if anything gets messed up you can program your other known good working BIOS files instead.

Im sorry but this is getting too hard for me. My brain cells are in agony lol.

Can we do that if i come any new problems i come back? Like i said that restore default thing is no big deal for me.

Is this ok with you?

Yes, no problem and I understand don't worry. If you run into issues again pop back in here any time!

I cant thank you enough. You have been great help.

You're welcome! Sorry the fix was not exactly 100% proper

So theres been bios update for this laptop. If i update it will i loose the Intel management drivers again?
