@heyheywill - Sorry, that is confusing, what's going on there and what is file from step #1? I have not sent you any mod BIOS yet, so how could either of thosbe "biosreg modified"
You were supposed to flash back in mod vars, then reboot and do step #1 only and send me the file.

Oh sorry about that I got confused about which bios to send. This is the right bios after using varsm http://s000.tinyupload.com/index.php?fil...413007832666201
@Lost_N_BIOS

@heyheywill - Yes, send me only new BIOS region dumped after you flashed in mod vars, rebooted, and made a new BIOS region dump (Sorry I did not clearly outlined that first time around! )
Here is unlocked BIOS - http://s000.tinyupload.com/index.php?fil...287460725482011
Flash it back via >> FPTw.exe -bios -f biosregm.bin

*** WARNING - To ANYONE with laptop and unlocked BIOS!!!! ***
DO NOT try to enable this graphics card or disable that card, switch cards etc. Otherwise you will end up with no display output (ie black screen) and no way to recover except by blind flash or with flash programmer.
You can change graphics related settings, like changing memory sizes, or core speeds etc, just don't try to disable one card or change which is main etc.
Additionally, be very careful when trying to undervolt CPU, you can leave BIOS unbootable due to CPU voltage too low (Sometimes even 0.05 is too much)

*** WARNING *** - This BIOS is user specific! If you are not user heyheywill at Win-RAID.com forum, DO NOT USE THIS BIOS!!
If you do, and you are not heyheywill, then you will loose your serial, UUID, OG NVRAM, and possibly LAN MAC ID as well.
You have been warned!!!

@Lost_N_BIOS

Thank you for your help.
I have successfully unlocked using the unlock ModBIOS you provided.

Ch341a has flash successfully and unlocked the advanced menu .

1. I can set the memory state to 2933 and stable work in 2933-17-18-18-42-cr1.
but the setting is higher than 2933 (ex 3000,3066,3200), Whatever parameters are set to 20,22,22,46 or 22,24,24,52 ,etc...
it couldn't pass the memtest . Whatever adjusted the mem voltage to 1.35v, VCCIO to 1100MV and VCCSA to 1100mv,uncore to +100
Do you have any other Suggestions for overclocking?

2. Try use FPT flash back dump bin still show 167 error after when FPPR is disable（ The default menu FPPR after the first boot is enable, and I can choose to turn it disable ）
3. abount Me Fw Image Re -Flash : Me Fw Image re-Flash cann't be set to enable ,Me Fw Image re-Flash status still is disable after IN BIOS set to Enable and reboot .

Attached is the BIOS that has been unlocked. I wonder if there is something wrong with it that makes it impossible to use FPT flash still show 167 error

Thank you again

@johnson2008 - Great to hear all went smoothly! So, you unlocked yourself?
Ohh, I see now, a few pages back I made you unlocked BIOS region, I assume you took that and put into your dump, then flashed?

For confirmation on read/write to your chip MX25L12873F, what software did you use? Thanks!

1. Memory may not be up to going higher. Can you confirm those all of those voltages change with HWINFO64 when you change them?
If so, probably memory reached it's max stability point

2. Lock needs removed in a BIOS module then, not sure if I can find it on this BIOS or not. I will look and let you know.

3. ME Re-Flash, this is meant for temp usage, set it once and boot to windows and reflash ME if needed (via FPT), It auto resets on reboot
Normally, if your ME FW is not messed up, do not use this or FPT to flash it, use ME FW Update tool, that way you do not have to configure a ME FW for your system using the clean/settings transfer guide

* Edit - The above attached file is not a BIOS flash programmer dump, where is that? This is only BIOS region, same as a FPT Dump

* Edit - I may have found bypass to 167, not sure. If you want to test it let me know, programmer recovery may be required if it's incorrect and bricks.

EDIT

Attached is programmer flash dump FD

Thanks.

@Lost_N_BIOS
thanks man!
i have successfully unlocked advanced menu of Acer Predator Helios 500 thanks to you unlocked my bios
i tweaked my Hynix memory from 2666 CL19-19-19-43 CR2 to 3467Mhz CL18-20-20-42 CR2 1.2V with uncore +075 v stable with memtest and prime95
that was a huge tweak i've ever do it!
i achieved 3200 CL17-18-18-39 CR1 1.2V stable.





i tweaked other thing like uv cpu to -125 and increase PL1&PL2, time turbo boost.
but there is ICC/OC i can't tweak BCLK

the behind of unlock my bios is to increase the frequency of all cores from 3.9 to 4.0Ghz or more
it is possible if mod ME Fw like unlock, it would be unlock OC's the cpu?

thanks man i really grateful to you

@johnson2008 - I don't know which file you want me to use above? FPT Vs programmer dump, you'd have to compare in UEFITool, FPT dump may not dump all regions, if FD has locks for any region on read access
For testing of the BIOS lock possible bypass, I can use/edit any "BIOS region" and send to you, since you know how to put into full BIOS for programmer, or I can edit full programmer dump, up to you. Maybe best to send me programmer dump, that way I can unlock FD for you if it's not already.
No matter what, be ready for recovery in case it's wrong edit and bricks system. Please upload programmer dump to tinyupload.com or uploadfiles.io, as a single zip/rar etc, or other free file host if there is one you prefer
If first edit fails and you want to keep trying, there is a few other modules I could maybe try editing, but this is not my strong suit, when this lock is not in standard common place I usually cannot see it properly (not enough assembly skills)
First edit I see is in PowerMgmtDxe, but there is also a BiosProtectDxe module which I could possibly bypass something in, not sure (or remove this entirely and test outcome).
This lock is usually in PCHInitDXE, but I don't see it in this ones PCHInitDXE module, could be because it's not there, or my lack of assembly skills.

@tonyG3 - Great to see all went smoothly, thanks for quick report back!
Also, nice memory overclock you've got going there

Yes, ICC profiles are ME FW controlled, sometimes even adding OC profile does not help though, but we can try. If it fails, program back original!
Never mind, I tested three ways and none will stick, I think due to HM370 chipset. I tried to change default profile from Standard to OC or Adaptive, on rebuild it's reset back to standard, and I tried enable profile switch and add second profile with Adaptive or OC, and on rebuild it's gone.
So, seems Intel has locked this down, at least for HM370. This is only helpful for Bclk change anyway, and that is limited 102.x on current CPU's, so not much to gain there anyway.

@Lost_N_BIOS I got this laptop about two years ago, cost me like $2000
as you can see it's 8th Intel processor and i want work as last intel gen, I plan to continue using it for at least 4 years
so I want to powered up all its capabilities as long as I have a good cooling system, cpu temp 75~81 at 3.9 all cores, i also plan to do water cooling like this
https://www.reddit.com/r/watercooling/co..._my_msi_laptop/
honestly, i need to push their potentials to the limit as long as i have a good cooling system that i can count on!
if this does not bother you, then i want try, so it may be a success.

cheers

@tonyG3 - as mentioned above, I tried to make the changes for you, it's not possible due to chipset (at least not the ME FW edit)
Best you can do is use throttlestop and lock all cores to same maybe.

* Edit - But, I can make some stuff visible to you in the ICC area, but without proper ICC profile I don't think the changes will apply, and may even brick on save.
Do you have flash programmer to recover? if it bricks on saving revealed ICC settings without proper profile?

* Edit 2 - Here, ONLY test if you have flash programmer to recover, otherwise changing settings in the newly revealed stuff in ICC profile area may brick BIOS

@Lost_N_BIOS i have ch341a that means not issue if my bios brick?

@tonyG3 - that means you are safe and can recover, provided you have known good working full BIOS dump from programmer already, or have backed up all regions with FPT so someone can rebuild a BIOS for you.
And, you also must know what software/version can read/write properly to your BIOS chip, so you're ready and know you can recover easily within a few minutes with programmer if it bricks, otherwise you'll be waiting around for help.

@johnson2008 - Nice memory overclock for a laptop system!
Here, program this in, then if not a brick, dump BIOS region with FPT and see if you can flash it back.
If still 167, then let me know how risky you want to go in testing (ie can remove BIOSProtectDXE entirely and see what outcome is .. brick, or FPT flash OK then etc)

@Lost_N_BIOS i flashed the test unlocked bios&ICC/OC
and no bricked bios and ICC/OC now it's visible i can set the clock frequency but on the reboot no applying , reset to 0
