@Kittymatthew - Thanks for quick report back, and great to hear all is unlocked without issue!
Yes, be careful, that is my general warning I post for all users with laptop and unlock BIOS
You're welcome, and thanks, you have a great weekend too!

hi i would like to unlock advanced bios mode you could help me acer predator helios 300 i7 8750h bios v1.26

@rdsadrian - Please give exact full model, then I will merge this into the main thread (if it's the model I'm guessing)

PH317-52

@rdsadrian - Thanks, it was not the model I expected, but we have a thread for that model, so will merge this now (removed your serial #'s)
Please do what is in post #8 and #12, and send me the files

I downloaded the folders I installed but it doesn't show any folder with var.txt

@rdsadrian - There is nothing to install from either post #, these are all just software packages that you run in place as I outlined in each post (#8 + #12)

For the vars dump, you have to run the command I mentioned at post #8, from each versions folder, so you get a vars.txt dump created from each version (this is multiple versions, in case one does not work, or does not dump all etc, so we do a few versions to be sure)
var.txt will not be there until you run the command I posted, from CMD Prompt at that folders location.

If you are not sure how to open a CMD prompt at an exact folders location, easiest thing for you to do then is to install the registry fix I put at end of spoiler in post #12, then reboot, then you can right click on any folder you want and choose "open CMD here as Admin"
For the vars, you would be selecting each versions folder (where the .exe is directly inside) one by one, and running the CMD from each versions folder one by one. Then once done, copy that somewhere, delete everything from inside each version folder, except the vars.txt and upload it for me in zip.

please help me I can't find vars.txt I managed to activate cmd but I can't find vars.txt

NVM 🤣

@rdsadrian - You have to run this command, from each H2OUVE version folder, then vars.txt will be created (if no error) >> H2OUVE.exe -gv vars.txt
If you can't get it, show me image of what you're doing in CMD and your H2OUVE folder (so I can see it's location)

@rdsadrian - I am on limited internet, please resize those images to 1000 px wide, then put in zip w/ max compression, thanks.

OK

@rdsadrian - Sorry, those images quality is too poor for me to read anything.
They do not need to be exact 1000 px wide, I just don't need to see 2000-5000+ PX wide images that are 2-5MB per image files, mainly because I am on limited internet and will only look at them for one second.
Please resize them to something sensible, few hundred KB per image is fine, and if you are having some site do the resize for you, it may be better to use PNG output

* Edit, I checked one of the above at post #26, those are OK! Sorry! Please zip those images as they are
* Edit 2 - Never mind, sorry for the delay, I checked the images at #26 as they are. You're opening CMD prompt properly, but I don't see you putting in the command in any of those images.
You do not run the exe, you type or copy/paste the command I gave you (will be below again), into each CMD window you open at each versions folder

H2OUVE.exe -gv vars.txt

Here, example of how it will look once you type in command. I can't hit enter after I type this, I don't have Insyde BIOS, but you hit Enter after you type this, then repeat same thing for each version
Then do as I mentioned, copy entire folder somewhere, leave vars.txt in place, but delete everything else and send back to me

vars.txt
