Well your current MEngine firmware seems ok , then the problem is more difficult, it might be that there is a lock on flashing the ME firmware but, it might be that the ME is somehow dissabled from running in bios, or there is actual damage to the powersupply of your ME engine, But that goes a bit beyond my level of troubleshooting. The real guru's who run the site here will be better at aiding you further i'm sure. Anyway , reading all the info there is concerning the topic on this site will sure help you also.
I hope you get it fixed eventually without too much trouble. Kind greetings.

@GnarZ77 Many thanks for responding and trying to help me.!

I hope someone help me :/

I tried to update the BIOS via USB BIOS Flashback, but it does not update, flashes, and then it just glows.

flash usb: formated to FAT, BRenamerl > Z77VB.cab

And when updating via EZ Update in BIOS, it updates and resets profiles, etc.

Any ideas guys?

@plutomaniac

CurrentState: Normal
ManufacturingMode: Enabled
FlashPartition: Valid
OperationalState: M0 with UMA
InitComplete: Complete
BUPLoadState: Success
ErrorCode: No Error
ModeOfOperation: Normal
ICC: Valid OEM data, ICC programmed

is normal status, yours is stuck at initializing.

Please also note at post #18 >> Z77VB.cab << Invalid BIOS name for flashback, unless typo, should be Z77VB.CAP. Also note, this method (Flashback) can only be used with Asus stock BIOS or other modified BIOS that is in a "Signed" encapsulated BIOS file
This cannot be used with FPT dumped BIOS, unless you put whatever region you dump back into a signed capsule - verify before trying to flash with UEFITool, do you see AMI Aptio Capsule - Signed? if yes, OK to rename then flashback

Thank you guys for your answers!

@plutomaniac Should I read and make the item D3. ME 7 - 10 & TXE 1 - 2 from your guide, is that right for me?

1. download the Intel ME System Tools v8 r3 - (2017-11-19) - For 6/7/X79/C600/C210-series systems which run ME v8
2. download the Intel ME 8 Firmware Repository r20 - (2018-07-07)
2.1. use file 8.1.70.1590_1.5MB_PRD_RGN.bin at clause 4

is right?

@Lost_N_BIOS yes, this is a typo, a .CAP file, I downloaded the BIOS from the asus website, following the instructions from the same site, also downloaded the BRenamer program to rename the P8Z77-V-ASUS-2104 file to Z77VB.CAP for Remembrance, my USB the drive was formatted in FAT, and I tried FAT32 - to no avail.

I thought it may be typo, but just in case it wasn't I couldn't scroll by without saying anything

Not all USB will work, smaller is better 128MB-2GB, sometimes you may need to try 5-10 USB Sticks before you find one that works, sometimes you can never find one compatible
Best way to test your USB stick is by flashing the stock BIOS via USB Flashback, once you see that is working with any USB stick, then you know you can use that one with your mod BIOS.
Also, be sure BIOS is put on the root of the USB, not in any folders

@plutomaniac I don't quite understand point #5

I need to fully load the bios dump into fitc, or I can only reflash the ME region?

@plutomaniac Okay, gonna try..

I dumped my BIOS, and threw the ME region into the ME analyzer

Warning: Firmware size exceeds file, possible data loss!

Go to Build > Build Settings... , untick the option to "Generate intermediate build files", leave all other settings intact and click OK.

If you are working on ME 7 - 9 or TXE 1, go to Flash Image > ME/TXE Region > Configuration > Features Supported and set "Intel (R) Anti-Theft Technology Permanently Disabled? " to "Yes". Intel Anti-Theft Technology has been EOL since January 2015 and can cause issues if left activated nowadays.

or this too?

If you are working on a SPI/BIOS image with ME 7 - 9, go to Flash Image > Descriptor Region > PCH Straps > PCH Strap 2 and set "Intel (R) ME SMBus MCTP Address Enable" to "false". Also, set "Intel (R) ME SMBus MCTP Address" to "0x00". These are Intel Anti-Theft Technology settings and these changes will stop the "MCTP 3G" error seen at Intel MEManuf tool when the former is disabled.

If so, what does it mean?

Note: These two settings are set at the Flash Descriptor (first 4KB of SPI/BIOS image) and not Engine Region. So for these to apply, you need to reflash the FD as well either by preparing a full SPI/BIOS image (FD+ME+BIOS) or by flashing it manually via a tool such as Flash Programming Tool with -desc command.

I have already successfully created the file "outimage.bin", but have not tried to flash.

For complete steps i need use command "fpt -f outimage.bin" and "fpt -greset" is right?

C:\ME\Intel ME System Tools v8 r3\Flash Image Tool\v8.1.10.1286\Build\Int\ME Region.bin
 

to execute this commands: "fpt -me -f me_region.bin" followed by "fpt -greset

@Lost_N_BIOS I made a flash drive in 128 MB formatted in FAT, and it worked, but the ME did not recover :\
