[REQUEST] Sony Vaio VPCEH & VPCEJ series (R0xx0Z9) BIOS Unlock
Hello everyone! I found a vpceh2q1e device somewhere. I want to open UEFI and its hidden features, can anyone help?

Hi friends, I received help from your skills before.

This time I bother you, because I have a

Vaio VPCEH2D0E, Bios R0180z9
Intel i7-2820QM
W11 pro for workstations

And I leave you a par questions:

The modded BIOS you uploaded here, would work also in my model?

Flashing the 200z9 or 210z9 version would the UEFI be enabled?

I found the recovery partition for W7 and could perform a refresh on legacy mode, but for W8~W10 to use the recovery system it seems to need a GPT partition. On the BIOS 180z9 there are no options to switch between legacy/uefi.

If possible, I'd like to try the 210z9 unlocked BIOS.

Thanks again for your help, if any of the mods wanna earn some bucks I'll be glad to hear which further modifications are to be performed on my bios and how much could I donate for it.

Thanks in advance, greetings

Update Installing modded bios 200z9 onto VPCEH2D0E:

I used the tools and rom provided and it all worked flawlessly, first the computer had all the menues visible but the the sata devices weren't recognized. While booting from an external disk, another inconsistency was that only 4 cores of the i7-2820QM were recognized, HT was somehow disabled.
After changing graphics aperture size to a lower value, the sata devices were recognizable again but the windows installation wasn't booting, the message was "boot source is inaccesible". I'll try a fresh installation of windows and will try a GPT partition under UEFI.
I'd like to try the modded bios 210z9 still, is it needed any special workaround on the BIOS to make a eGPU work correctly on this model?

The modded BIOS worked, the installed minipcie USB 3.0 module works, this far the computer is booting but with unpredicted results:

No Hyperthreading on i7-2820QM, graphics size over 256MB for Intel HD 3000 made SATA drives unrecognizable (believe it or not)

Links of the dump files before flashing:

I'll report any other updates, thanks in advance.
