(UEFI) Dell XPS 15z L511z modded BIOS - and HOWTO

[anscorp]

Hello all.

I need some help.
My notebook is not a DELL, but a Brazilian manufacturer called CCE (hm61 and i5-2410M).
He has a BIOS / UEFI Phoenix Tiano Securecore with menus blocked.
Need to enable UEFI boot to get my osx start correctly (actually also need to enable sleeping).
Extracts my bios with Phoenix Mod and found CFEF94C4-4167-466A-8893-8779459DFA86_1_941.ROM referring to platform_setup_advanced_dxe.efi. With the Hex Editor I found some occurrences of 0A 82 45 8A and 0A 82 45 0A, but already followed all of 01, ie, with the menus activated. (!?)
But the options do not appear. Very upset, I risking something that could eventually damage my motherboard. I dump CFEF94C4-4167-466A-8893-8779459DFA86 modded the rom posted here, I inserted in my bios, and flash my notebook.

The notebook boot ok. But upon entering the setup, I get warnings:
1º
Formset 78D3BC87-78A3-4996-B813-1844050889F7
FAILED TO LOAD STORAGE: SETUP. STATUS: 0x7.
OK

2º
Formset 78D3BC87-78A3-4996-B813-1844050889F7
Failed to load storage: DellVariable. Status: 0xE
OK

3º
Formset 78D3BC87-78A3-4996-B813-1844050889F7
Failed to load storage: SSDExist. Status: 0xE

4º
Formset 78D3BC87-78A3-4996-B813-1844050889F7
Failed to load storage: SioPolicy. Status: 0xE.

After that enter the bios normally, but when entering the Advanced tab, it takes a while but it opens with all options unlocked. But changing some option when I save the changes, I get the first warning again. But back to the setup option has not been modified.

Help me. I really want to have the UEFI boot enabled.
