Hi I need so help to unlock the bios of my laptop (Acer Aspire A717-72G-752W). I want to unlock the advance tab in the bios. (Like in this video https://www.youtube.com/watch?v=uJV3Rtmb7Jk) But I don’t want to use a CH341 programmer for that. I found this on the forum but it’s not the same model nevertheless i think it’s possible (Acer E5 571G 51DS Bios Unlock).
I want to know what are the risks also because i don’t want to mess it up
What you do is wait for help Please edit your posts when you want to add more info and no one has replied yet - thanks
Some model of system that’s not yours is not related at all, and means nothing when it comes to unlocking or if it’s even possible. You may or may not need to use a flash programmer, some BIOS this is the only way it’s possible, others this is the only way it’s easy, some you cannot do even with programmer.
Thanks for posting all the necessary links and BIOS files etc. Please slow down now before you brick your system! FPT can brick in a hurry if used incorrectly, so wanted to warn you now, slow down and wait for help.
I will check your BIOS now and edit this post with more info shortly, specifically and initially on the 167 error since that is first obstacle.
So at grub prompt type each of the following one line at a time (enter after each ) setup_var 0x17 0x0 setup_var 0x6D1 0x0
Both may fail, and you may need to use another tool instead - Please send me image output of any error messages from each command, in case it contains info I need.
This tool I’m sending you multiple versions, try each and if any give you the txt files rename them to filenameversion.txt so you know what they came from, so same can be used to write back once we’re ready/ If multiple give you the txt files, send me a copy of the ones from version that creates the largest files http://s000.tinyupload.com/index.php?fil…932311127599521
From command prompt, at each versions folder location, run the following commands for each version H2OUVE.exe -gv vars.txt H2OUVE.exe -gs -all Setup.txt
Normally, this system does need to use programmer, as mentioned here, but maybe we can get around it (Possibly not, and in case you ever need it, order CH341A and SOIC8 test clip cable now, both are less than $7 total shipped on ebay) https://www.bios-mods.com/forum/Thread-R…72G-BIOS-unlock
Download the .efi file in the guide I linked, rename it as mentioned in the second link I said applied to you. I do not prefer Rufus, or FreeDOS, sometimes it can cause issues. Here is my suggested method to make DOS Bootable USB - (Follow steps 1-4 to create bootable USB) <Request> Flagship X470 Gaming 7 Wifi Motherboard BIOS Fix
@Lost_N_BIOS I think i am a little bit stupid because i can’t use that utility since i get the same error for multiple USBs (Annotation screenshot)
EDIT1: I did all the things by hand and I got this (GRUB screenshot) but I think that didn’t do it correctly I created a efi folder on the pen drive and i put the boot/boot64.efi inside from EFI-Setup-FPT-Universal-IFR-Extractor.zip and I also pasted the USB-Boot content to the USB root (DOS usb screenshot)
YOu have it all working properly! At least in your first “GRUB” image. Not sure what’s going on in your GRUB2 image, you are trying to set 0x17 again which you already changed previously? So, you disabled BIOS lock, but can’t get FPRR disabled, nothing new here, I told you it’s a pain!
Not sure why your USB is write protected?? Maybe due to you are in UEFI Mode, not sure, I’ve never seen that exact in dead/dying USB/SSD when you can’t write to them.
Nothing new at the link you mentioned, all the same three versions I sent you to use. These are the only publically leaked versions that I’ve seen
So yes, 220.127.116.11 works for vars, hopefully that will be enough, or lead us to the correct GUID to edit the rest. Let’s confirm this is all, and maybe give you another way if UVE doesn’t work properly Please do same thing for these apps as you did fir H20UVE, run each 32 and 64 command from each versions folder, keeping all files in same place. Once done, zip all back up in a single file for me. None may work, it’s OK, just something to check in case it will work http://s000.tinyupload.com/index.php?fil…603526132448404
In grub, using setup_var, if you want to check a settings current value, only type the command and variable (no setting at end). Here’s an example to check value of variable for fake 0xQ2 setting >> setup_var 0xQ2 The other Intel Insyde programs are not for what you’re doing here, only UVE
For the last package I linked you too, SCE, the commands to run for 32 and 64 bit are inside in a text file. This has nothing to do with UVE program, and this does not use anything like the commands you have written above, please check the text file included in the SCE package
I checked your SCEWIN attached package, and only two versions are in there, does that mean the other two didn’t produce output? Ahh! Sorry, I remember these only work on AMI BIOS now anyway, sorry! Always trying to find all solutions before telling user programmer is the only way, but it may come to that.
Here is edited vars.txt. Please pay attention and do only and exactly as I mention here or you can brick your system Take the varsM.txt file below and put it in your H20UVE 18.104.22.168 folder. Then run the following command from admin CMD Prompt to program back in
Once done with that, do not reboot, dump the vars again using the following command and then compare varsm.txt and varsmcheck.text with hex editor, are they same or not (?) If they are the same, fine, reboot. If you are not sure, or can’t check etc, do not reboot and send me that varsmcheck file and I will compare. This is to make sure what you wrote in was applied properly
H2OUVE.exe -gv varsmcheck.txt
If all looks correct and varsm.txt matches varsmcheck.txt exactly, then reboot and then come back to windows and try FPT flash of stock biosreg.bin back into BIOS again
