Hi, just registered to share my experience and thank you for the detailed instructions.

I successfully modified the BIOS for ASUS P8Z77-V Pro/Thunderbolt and I'm using a NVME SSD with a Jeyi PCI-E adapter. The process was quite straightforward and I flashed using the Flashback USB method. Had to try 2 different USB pendrives but the second one did the trick.

Well, I'm going to give up the idea to use a NVMe drive in my laptop, nothing works...
I tried to flash the modded bios but whatever the method I use, the system refuses to flash the modded file because it has the same build date than the current one (I modded from the last update which is already the version installed on my system).
The clover workaround doesn't work either so I'm not going to loose more time on that bull***t laptop

@Fernando Thanks for your help anyway

Which method did you use to achieve this with the GA-7PESH2?

@Neutral67fr - see my guide - [GUIDE] Grub Fix Intel FPT Error 368 - BIOS Lock Asus/Other Mod BIOS Flash
You can start at step #6, because here is your variable to unlock >> 0xAE

Pay attention to the guide warning, make a backup first and then apply your NVME edit to that, then flash as directed.

@daedalus - here is mod BIOS for you - http://s000.tinyupload.com/index.php?fil...358984200689167
Replace image.bin at SPI-UPD folder, then use option [1] = use FPT flash BIOS, Afudos flash ME. Please don't set ME Flash jumper - Or, you can use #2 as well, set jumper
Or [3] = use AfuDos flash BIOS. (May fail, unsure if security check on AFU or not, that's why I suggest #1 or #2 first)

@Lost_N_BIOS Thank you for your help but I don't think the guide you mentioned will help to solve anything as at the end the UEFI ("bios") chip refuses any update with an less or equal bios file build date than the current version. So I guess that even there is any kind of other signature verification (in case of a modded file), no flash is possible at that time...
I would need a trick/tweak to change the date build inside the modded bios file or find a way to first downgrade to a previous bios version (which is basically the same date problem).
I obviously don't want to brick my laptop so I prefer stop here, the gain is not worth the risk ;-)

@Neutral67fr - This does not matter, the method I linked will work 100%. Intel FPT does not care about "AFU" or Asus "EZ Flash" rules or security verifications etc. Follow as I mentioned and you can flash anytime!
This is designed method to get around Asus security method, well known issue of which there is many solutions. Build date can be done, but would also need flashed in the same manner I linked (it's modified BIOS if you change the date, thus you must use this method)
100's of people use this method and others to get around Asus flash blocks all day long, as well as Asrock and many other brands with similar locks as well.

I help people around Asus security and modify Asus BIOS all day long, trust me you can flash using my method, follow what I said though >> Backup via FPT, mod that, then unlock BIOS lock, then flash your modified backup via FPT.. done

@Lost_N_BIOS Well, I'll probably have to read the guide 10 more times to understand well each particular step before trying to do anything
In the meantime thanks for the tip

Just to confirm, I don't need to do anything posted at the start of the guide; just drop the image.bin file into the latest version of the BIOS into the SPI-UPD folder, and then use FPT to flash it onto my motherboard?

I have a question which is probably off topic for this certain thead, pardon me pls.
I've successfully modded and flashed BIOS and cloned my HDD to SSD. But now I simply cannot boot. No errors though. I see my SSD detected by UEFI BIOS as "Pata SS:". But when I try to boot from it it simply doesn't boot up OS and throws me back to UEFI Bios Setup screen.
My config is: mobo H81M-K, Samsung EVO 970. I see SSD in Windows, I cloned my current Windows OS to it using EaseUS Todo Backup app.
The only thing that I could come up for now as a possible reason of the failure is that clonned system uses MBR setup instead of GPT. But frankly I am not sure that is what I'm looking for in my case.
Fernando, could you pls help me! Thanks in advance

@Fernando:

Hello, and thanks for warm welcoming of me and every who comes here for the first time. It's really nice of you!
It's late night here and I'm on production set, so I have to force it working till the 6 am which is soon.
So, I actually didn't get that you just said - you reccomned to clone the formely used system drive to the NVMe SSD? you do or you don't? If you do then it's all illogical to me because that's what I have done and having issues with.
But you didn't answered about the MBR and GPT nuance I've asked about. Is it possible to boot from MBR partitioned NVMe SSD at all using this BIOS mod?
We have server with a lot of settings stored on it, we cannot simply throw it away and reinstall system. Also I don't have testings platform I need just clone the disk and make it work.
Any comments pls that could help, would appreciate a lot.

Update:
The only sentence I have found in the initial message of this thread about cloning is this:
"Another option is to do a clean OS installation in UEFI mode onto any SATA connected SSD (a suitable NVMe driver should be available for the OS!) and to clone the complete disk drive content onto the NVMe SSD. "
BTW installing in UEFI mode - is it a guarantee that windows will choose GPT over MBR automatically while partitioning?
And what difference between installing Windows first on SATA HDD and cloning later to NVMe SSD vs. installing it on SATA SSD with cloning? What part is neccessary here - isntalling on SATA SSD or installing in UEFI mode or both? Actually I don't see any difference between SATA SSD and HDD as far as I am aware about partition aligning and stuff, am I right?
I simply don't have time, testing platform, spare SATA SSD, spare HDD, and ability to kill the OS to reinstall it from the ground and right to make mistake. My bad. So is it all about having GPT setup? Does it possible at all to boot MBR rigged disk with that mod, have you or anyone else tried it before?

@Fernando:
Thanks for your help, what I meant was, in addition to adding the image.bin file that @Lost_N_BIOS supplied to a stock BIOS, I also need to follow the rest of the steps at the start of the guide correct?
