Hello! please i have acer vn7-791g and
Advanced and Power menu are hidden.
I need access to them.

any one ?

@megan - Sorry I missed your post until now!

Please do the following and send me file from step #1, and also please link me to your stock BIOS download page (not the BIOS, the page to download BIOS from)

everything is ok until step 2

-----------------------------

i forgot to ask you you said : Please do the following and send me file from step #1

and you said again: Please don't send PM's for help on BIOS edits, I can't help with BIOS in PM's. Please make a thread and I will try to help as soon as I can - thanks!

so where i can send you the files ?

@megan - Yes, this is expected error, thanks. Error 28 may be an issue though, you may need flash programmer to get past this, but we'll try without first.
You can attach file in thread, or upload to any free file host and post link here. If you want BIOS hidden from public, you can send me link in PM, it's OK.
I just have that in my signature because I get lost instantly trying to help with BIOS in PM's due to no information and previous replies are not there every time we reply back an forth

Error 28 is a major pain, there is a few possible programs you can use to bypass, but it's risky and not ideal to try without flash programmer in hand and backup made, so then once you have those you wouldn't need to try that method anyway, so kinds pointless then
For now, please try this and see if you still get error 28. Put system to sleep (S3), not hibernate, for one full minute or longer, then wake it up and step #2 from windows again and see if you still get error 28 or not.
This is BIOS sleep bug, if you still get error 28 then your BIOS does not have the bug

i think it worked ?

@megan - Yes, nice! You're BIOS has the S3 sleep bug, so no programmer needed

So now, send me the original FPT BIOS region dump you got from spoiler at step #1.
If you want this kept private, and you send me in PM, remind me of this when you send the download link, so I don't post the mod BIOS here

ok check you pm please

Mod BIOS sent in PM, please report back here success or fail etc, thanks
If you cannot enter BIOS it's OK, we can fix via FPT reflash from windows with your original dump. I only say this because I've not unlocked BIOS like this exactly, so maybe did 1-2 more bytes than necessary, but I think it should be OK
* Edit - Wow, Tinyupload slow today! If you need mirror let me know!

omg!! its working with 0 problem thank you so much


-------------------------

can i unlock 135 mhz limits?


-------------------------

i tried gpu-z but i get error message

i also tried nvflash but no luck

I thought if i unlocked the bios i can access to vbios

@megan - Thanks for quick test and report back! Good to see all unlocked
You should have mentioned to me sooner that you wanted to edit vBIOS
No, getting unlock on BIOS has nothing to do with vBIOS access. When you can't dump vBIOS via NVFlash or GPU-z, that means vBIOS is part of the BIOS.
Here is your vBIOS, rename to .bin, sorry I forgot. You can edit with Maxwell II BIOS tweaker - http://s000.tinyupload.com/index.php?fil...118434182843205 >> Mirror, since Tiny's been down all week (@ ket) - https://ufile.io/ith1zbco
Send back to me when you are done I will put in mod BIOS for you

Also, you can bypass 135 limit with MSI afterburner program - https://forums.guru3d.com/threads/how-to...rburner.338906/

Thanks @Black Raven - Maybe you can make the desired changes for megan is she does not get it with the guides above

Or megan, you can leave vBIOS edit alone and do what you need via unlocked MSI afterbuner? This is MUCH safer thing to do!

Seems to be whenever someone needs a good technical guide my name pops up @Lost_N_BIOS lol.
