[Request] BIOS Unlock - Acer Predator Helios PH315-53

Ofc there is a password. Vernnon must have set it. Ask him, because I don’t know the password.

Hi Friend @ItsTheEternity, send me a PM and i’ll send to you the pass…

@Sweet_Kitten Hi Bro, how are you? I getting a new predator (i love this model) and i`ll need to unlock the bios. Version is PH315-54-70LH. can you send me the tools to extract the vars and send to you?

From the moment I got tired of making BIOS mods and the moment I discovered the power of PowerShell, BIOS backups and its variables are no longer required.
A windows batch script is awaiting: Acer PH315-54.

What this tool will do? Can you give me a little brief of it? @Sweet_Kitten

It’ll do the same thing I do to unlock, but in automatic mode.

First - sets variables. It reads them, edits (new) and writes to memory.
Second - modifies the BIOS. It reads the BIOS to a file, edits (new) and flashes it.
Previously, I would left editing to myself, because I did not know how to automate it.

So, how it does edits varibles:
H2OUVE program saves the “PchSetup” into a text, then the script locates strings “00000010” and recedes 35 chars right, locates strings “00000680” and recedes 8 chars to disable BIOS Lock 0x01C and FPRR 0x683 accordingly.
Finally, It edits BIOS image using UEFIPatch (functioning as UEFITool) program along with the patches prepared in advance.

@Sweet_Kitten the last question: this tool will open advanced settings in bios or only enable the undervolt option?

The script aims to open advanced settings. Except settings of memory, these are unconfigurable on 315-54.

@Sweet_Kitten tks one more time buddy, as soon i got the laptop i test and let you know…

using you scrit it gave me this error:

Error 167: Protected Range Registers are currently set by BIOS, preventing flash access.
Please contact the target system BIOS vendor for an option to disable
Protected Range Registers.

I never cease to wonder why FPRR disabler scripts only work for some people, as for ybbob for example. And can’t understand why, his bios was unlocked and I didn’t even ask for a variables backup. I agree that sometimes this is my mistake in choosing the right version of the Management Engine, but this is due to inattention. Although I pre-test all the main things that the script does and its all good.

I want to ask you, did you use the script files just after you downloaded the archive, today? Before you, there was another user who also had no luck with script working. It was yesterday and after that I did some work on it, but all the same. I thought it somehow would work for you.

@Sweet_Kitten i did download the script i think 3 or 4 day ago…

@Sweet_Kitten i’ve download again now and the same error happens…

Then I’ll unlock your BIOS in the usual way.

Run the DUMP.bat from this archive to obtain a backup of your BIOS (it’ll create biosreg.bin file in a working dir). Also, I need a copy of your BIOS variables, run “GET VARS.bat” from this archive (it’ll create vars.txt file in a working dir). Share with me the output files.

@Sweet_Kitten here we go:

Hi friends. Excuse my poor english. I have an Acer Predator Helios 300 ph315-53 with 2060, and I’m later to unlock my 2.04 portuguese bios version. Can I use one unlock bios publish here or I have to send my biosreg and vars, or results20.rar archive?

Better send, no?

Thanks @Sweet_Kitten @Vernnon

@ricardofariateixeira each computer has it OWNS configuration, don’t use the files posted here because you can brick you laptop. Yes, you need to dump your Bios and vars and wait someone here to help you (I’m not one)…

Hi Vernnon. Thank you so much.
Even if you are not the one who can help me, is it possible to know if the file I sent through the sendspace.com link is what someone need for help with this update?
Thanks for your help!

@ricardofariateixeira yes, these are the files that you need…

Thks Pal!
