[Guide] Howto Unlock/Flash an Insyde H2O UEFI BIOS

[DvL]

Look at this topic: [Acer V3-571G] How to unlock this BIOS (Advanced settings menu)? version 2.21

In that case (for the unlocking part):

@Lost_N_BIOS

Here is the unlock edits to make, extract that "DriverSampleDXE-SetupUtility PE32 "BODY" Edit body at two bytes as follows
8DE: 59 >> Change to >> 00
8E8: 4F >> Change to >> 00

But those edits you need aren’t going to be the same. Then he said:

@Lost_N_BIOS

That BIOS module is in all BIOS, it’s the "Setup" module, some BIOS call is Setup, other BIOS it’s DriverSampleDXE or SetupUtility etc.
So yes, all BIOS have this, and often with Insyde BIOS yes this is the module you need to edit to unlock, but it’s never going to be those exact same bytes to edit. To find what you need to edit, there’s several ways, some better/easier than others, and not all work on all BIOS even if it’s still Insyde BIOS
Here is a general method to figure it out for many Insyde based BIOS - http://web.archive.org/web/2016111807325…power-tabs.html

So basically for Insyde you just need to know the assembly instructions to get the bytes you need to edit (be a developer) or use the tool he linked.

That topic also contains info on the other modding steps we have taken (as you said, "unlocking/updating/modding/flashing")
