Unlocking Acer Aspire 7720G BIOS and available updates

[erlisd]

Hi all,
I have an Acer Aspire 7720G and I want to update and unlock the bios.
I saw a previous post here and used those steps, but the update was not that efficient.
Now I see some text overlapping and when the laptop powers up, the BIOS is not that fast.
I was wondering, is there any upgrade for this BIOS? Also including the option to unlock all
the options it has, and of course it has to be a stable version.
My laptop' BIOS specs:

Code:
