@Sweet_Kitten

This is the only photo I wanted to get. I recommend not to get carried away with setting parameters from this menu, because it is just as dangerous as changing the primary graphical device. Regarding to System Diagnose, it seems that for this reason the menu was originally removed by the manufacturer.

Here you go

@Sweet_Kitten

@Thats1947
Your BIOS MOD: Thats1947.zip.

Is this the final version with everything unlocked and system diagnose option removed or should i wait for a different one from you?

[Sweet_Kitten]

@fyrplay
Many thanks.

@fyrplay

or should i wait for another one from you?

I think this was the final version. I meant, this one I uploaded is for another user. Do not flash other user’s bios.

Thank you too @Sweet_Kitten for unlocking the options.

Also if i want to go back to the original version what should i do? The installer from Acer errors out.

@Sweet_Kitten

Do not flash other user’s bios.

Wait so someone with the same spec laptop shouldn’t flash this on theirs?

There are two options. I can modify BIOS updater from support page or you may take the bios region file from "results20.rar" archive and replace the one that is from bios mod archive I sent you.

Everything is simple: DMI data of your device will be replaced with data from someone’s BIOS in this case. DMI contains serial codes and other unique stuff.

The 2nd option seems better, should i also replace the vars file with the one i shared first or just use the current one from the last bios zip you shared…

No need to replace vars.

Thanks mod working good. I recommend changing color depth from 18bit to 24 bit

If anyone else has a modded bios and changed the wrong settings and now your laptop wont boot properly. You can download the official bios from acer website and extract the exe with universal extractor. Look for a abobios.bin file and drag it to a usb drive formatted to FAT32. Rename it to C5PRHX64.FD With laptop turned off hold down Esc and Fn and turn on laptop with letting go of Esc and Fn. Fans will spin loud and bios will begin flashing. Laptop will automatically reboot.

That’s not the right name for PH315-54-XXX, its…

1
 

GH53Gx64.fd
 

Follow these steps to recover ...
1. Extract the bios file abobios.bin from the BIOS Installer from Acer and rename it to the above written name, make sure the extention is .fd and not .bin & the size of abobios.bin shouldn't be more than 38694960 bytes.
2. Format a USB drive to FAT32 and copy the renamed bios file inside the drive.
3. Connect the charger to the laptop and keep it connected to power until the whole process is complete.
4. Connect the prepared USB drive to the laptop.
5. Press & hold ESC + FN key and press Power Button to turn the laptop ON and let go of ESC & FN key.
6. Within seconds the fans will spin at max speed and after a while it'll detect the file inside the prepared USB drive and flash the BIOS.

Process can take upto 10 mins so have some patience & don't panic. Once it's done it may not reboot automatically so disconnect the charger and press the power button on the laptop, you'll see the laptop's keyboard light up again and again few more times and finally it will boot fine.

Thanks @Sweet_Kitten for the proper name

[Thats1947]

Doesn’t work. The fans spin at max speed but the laptop reboots after a few seconds.

Works fine, try using ports on the left.

I used all ports but laptop doesn’t flash. I am using a 16mb bios file with correct name on fat32 usb drive.

[Sweet_Kitten]

@Thats1947

I am using a 16mb bios file

What the 16MB bios file? Mine is 36 and has "IFLASH" signatures.
RECOVERY.zip

[Thats1947]

I have the file in the zip you provided with a fat32 formatted usb. File is in root of usb. I plugged the USB in and did the FN + ESC and power method. Laptop fans get loud then laptop reboots after a few secs. Sometimes laptop fans stay loud but doesn’t seem to be flashing as light on usb only blink for a second then stop. I left it in that state of about an hour but when I reboot I receive black screen. I plugged laptop into a TV but receive no signal

[Sweet_Kitten]

@Thats1947

when I reboot I receive black screen

Something bad happened. I suppose the BIOS cannot be recovered by a file with a different version. In the archive it is 1.08.

So your laptop accepts files with two names for recovery?

@Thats1947

C5PRHX64.FD

[Thats1947]

I think the problem is the laptop reboots automatically before it can begin the flash process.

[Thats1947]

Laptop doesnt seem to want to accept the filename. Is there another file name I can try to see if laptop flashes.

[fyrplay]

@Thats1947

I am using a 16mb bios file with correct name on fat32 usb drive.

Bruh not the 16mb bios file, use the extracted bios from the BIOS installer from Acer and make sure its the same version that your laptop is/was running before it got bricked.
Filename should be GH53Gx64.fd

[Thats1947]

Laptop doesn’t read usb for bios recovery. My USB seems to blink once and that’s it.

[Thats1947]

Any help I still can’t seem to recover the bios of this laptop?
