[REQUEST] V5-571(G) BIOS unlock

[charlieporth1]

Hi, i want to change my dedicated vram, but.. u know it's limited.

Can anyone unlock the Bios?
Acer uploaded two different bios versions.

First: "BIOS - UEFI for Windows 8 (Not for Upgrades)" (v2.17)
I don't think this is the real Bios. There is a 13MB cap File in it.
Anyway, for completion:
original File (exe): https://www.dropbox.com/s/jugmprr7qybto1...17_A_A.zip
extracted and repacked (zip): https://www.dropbox.com/s/h791pxmm9uxwimn/VA410217.zip

Second: "BIOS" (v1.20)
This seems to be the real Bios, it contains a rom file. Edit: No, it's just an old version.
again the original: https://www.dropbox.com/s/j83f1dn9kribuh...20_A_A.zip
and the rom only: https://www.dropbox.com/s/5kq6rlszz17rj8n/VA41120.ROM

The title in the Bios is "Phoenix SecureCore Tiano".

Phoenix Bios Editor does not work. The PhoenixTool can extract a lot of things.. but i really don't know what to do then.

You would make me really happy.


Edit: Managed to figure out a module that could be the chosen one... thanks to Module-Helper (http://www.bios-mods.com/software-releas...le-helper/)

It's this module: OilSetupMainDxe from the v2.17 (https://www.dropbox.com/s/2i5uandngbq15i...6_1951.ROM)

Edit 2: There is also a String like "OilHiddenPageConfig" in this file. Lets see... Maybe someone could help me there.

Edit 3: Let me crosslink this thread (Acer Aspire V5-531) as there should be a similar bios.

Edit 4: Nothing? :-(
Edit 4:  could you please make the bios for 2.18 THX

Not exactly, you can open the notebook and find the bios flash chip and remove the resistor that goes to WP#, you can see that in the datasheet of the flash EN25QH64 or the one in your flash chip. Well, if you're going to desolder something and resolder running the risk of making something wrong, you can´t miss removing or even damaging only one "not so much usefull" component. Power to the user.
" WHDIS bit. The WP# and Hold# Disable bit (WHDIS bit), non-volatile bit, it indicates the WP# and
HOLD# are enabled or not. When it is “0” (factory default), the WP# and HOLD# are enabled. On the
other hand, while WHDIS bit is “1”, the WP# and HOLD# are disabled. No matter WHDIS is “0＂ or
“1＂, the system can executes Quad Input/Output FAST_READ (EBh) or EQPI (38h) command
directly. User can use Flash Programmer to set WHDIS bit as “1＂ and then the host system can let
WP# and HOLD# keep floating in SPI mode. "
