In addition to my last post from 1 hour ago:

I just updated the unlocked ROM to vBios 75.17.48.00.0C by myself, and it works just fine! (also shows the updated version in BIOS setup menu).
So i think you could just wrap up on the rest of those updates without that, ill just re-update it ontop of it, spares you some time.

Zitat von Lost_N_BIOS im Beitrag #14
REV75.17.48.00.0C Is update to >> REV75.17.48.00.0A ---- 75.17.62.00.09 may be update as well, but since both 09 and 0C in that BIOS, I assume these are for different model cards, either due to slight chipset variant, memory amount, or some other major spec difference



By now, I also successfully updated & flashed vbios to 75.17.62.00.09 which so far works without issues.
I will comment on its stability again soon.

@DvL - Thanks for the video info, I'll get into this again shortly.

N14M-GL variant of GF117 card supports DirectX 12.0, maybe some other variants do not, and some have only 1GB memory. So this may be why there is the two vBIOS for the same GPU
That, or it's due to one 710M variant is Fermi GF117 and another is Kepler GF208 https://www.techpowerup.com/gpu-specs/geforce-710m.c2017 & https://www.techpowerup.com/gpu-specs/geforce-710m.c2433

Some of the vBIOS in there are for GK107 and GK108, I assume you noticed that, but in case not I'll drop here for you or anyone else reading later.
I see when comparing the two original GF117 vBIOS and the new ones from the E1-771 BIOS, both in the E1 are same SKU but different vendor ID (This doesn't matter), but in the original two vBIOS from 571G BIOS, those two have different SKU's
On this one with other SKU, it also opens to Base Entries #3 instead of #1 (And all clock # entries have lower speeds too, core and Mem), so that may be for some lesser/budget SKU
So, my best guess is both/either of those from E1-771 could be used, and Vendor ID could be left as-is or changed later if found it needs to be changed.


Thanks for the LAN ID string. I also need you to confirm your LAN Chip is one of the ones in the list at the link I provided earlier, follow the links from that link to the two other threads linked with it's info/description about the mod, once has a long list of chip ID's.
Tell me which chip you have.

* Edit, looks like you replied again while I was typing out my reply, got ninja'd, and you confirmed my thoughts about those two 771 vBIOS

* Edit @DvL - on the Broadcom are you sure that's DEV_16B5 (b5) not DEV_16B5 (85)? I see 85 in the actual file in BIOS.
* Edit 2 - @DvL - Never mind the above, I confirmed that's what it's set as correctly being the Dev ID, so made update match current

All done!!

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
l


Sorry to kind of ask kind of an unrelated thing, but this is the exact thing I need help with. I have extracted the SetupUtility module and the SetupBrowser module(These ones: https://ibb.co/3TrJ4qq and https://ibb.co/2jMVFrm ), but I don't know which one to edit and what to search for(The codes given here are different for my bios), so if you could provide the unlock edits to make(or how to find them), I'd really really appreciate it, thank you. Here is my bios ROM(the one I got off Sony's website for my VAIO model which is a SVE1512Q1E): https://www.mediafire.com/file/agyl19d3y...0200D5.ROM/file . (The 9MB file size is not an issue, i could flash the file just fine)
Also, does this unlock BCLK overclocking and if not, is there a way I can add a BCLK overclocking module to the BIOS(i hope what i said makes sense). Even if not, I'd be grateful for all the other options unlocked.

I apologize again for this huge delay; I relied on e-mail notification for new posts and didn't get one. The user that posted now alerted me to it :)

Actually, that makes me get lucky, because I verified that after updating to both BIOS versions (made sure they were GF117), my GPU clocks and available memory remained the same. There's also no deterioration with a benchmark. So if that's true, then apparently the firmware applies the intended config again.
There's been no issues with the new vBios, in fact I think the GPU is faster now.

@DvL - Thanks for the video info, I'll get into this again shortly.

Edit: I noticed the clocks are the same between updated vBios and V3-571G original, didn't see you were talking about differences between various rom's I collected to see which would be updated. So no worries : )
vendor ID difference so far hasn't had any effect



* Edit 2 - @DvL - Never mind the above, I confirmed that's what it's set as correctly being the Dev ID, so made update match current

Thanks! I really appreciate it, finally we're done. I couldn't have updated this all alone (yet).
I'm going to flash it in the next hour, and will let you know of the results. If it then runs stable, we're set for a public modded BIOS release.

#20 RE: [Acer V3-571G] How to unlock this BIOS (Advanced settings menu)? version 2.21 by DvL 20.04.2019 21:15

The updated BIOS flashed successfully and seems to work just fine. Updated dependencies are showing the new version numbers.
I will comment on its stability soon!

Insane amount of advanced options.. I will demonstrate it with a slideshow once I open the modded BIOS release topic.

One last remark @Lost_N_BIOS ;

Zitat von DvL im Beitrag #11
[quote=Lost_N_BIOS|p75614]
So, no missing settings that you could see so far? If any still missing I can still make visible for you, but I need to know exactly what submenu or settings by name etc.



the only thing I am missing, ironically enough, is RAM voltage (and other advanced options like timing, etc). I can't seem to find anything related in your list either. RAM frequency (memory clock) is available, though. The mod is already awesome, but if you could find a way to get also that working, it'd be even better.

EDIT: I missed this earlier;

Some of the vBIOS in there are for GK107 and GK108, I assume you noticed that, but in case not I'll drop here for you or anyone else reading later.




yes I realized, others interested in this BIOS should understand that they will end up using their old video BIOS, as we only updated the ROM for 710M GF117 chipset variant. The other oroms are still loaded as original from V3-571G base model, and accomodate each model of that range like usual.
The point here is that we got no testers owning said models that can see if it works as expected (with a theoretical update) even when I would find updated ROMs for those GPU's like I did for my 710M. I can look into doing that later in the release topic though; offer 2 flavours, one with all standard vBIOSes (except for the tested geforce 710m update) and others with all updated (need testing for submodels), or just wait for an user that has it and is willing to test while requesting it. I will actually try to host this and update it on demand in that topic, so more models can benefit from vBIOS update than just those that own submodel v3-571g-73636G50Makk)

However, when owners of other V3-571G models upgrade to the modded BIOS (like it is right now), even though automatically using their original vBIOS, they will still benefit from the advanced settings unlock and other BIOS firmware/dependency firmware carried out by you.

Successfully flashed in CRISIS MODE your Acer V3-571G-_2.21-Q5WV1221-UnlockUpdate_ModFinal.7z on my Acer Travelmate P253, works fine!

Acer Aspire E1-531 - G - E1- 571 - G - V3-571 - G - TM-P253-E - M - PB EN TE11HC - PB EN TV44HC - GWNE56R
All these laptops have same motherboard and same bios, so your updates are big improvements since last 2.21 official bios in 2014 !

There is one WARNING! Do not modify advanced VIDEO and UEFI - it will brick laptop, see other forums HELP posts..

Lost_N_BIOS, DvL - big five you for your good work, especially for 710m bios mod.

I'm interested, what video chips I can install instead 710m??? Can you list to me all bios video chips what are supported by your mod. Same is to CPUs. TNX

@Kurtisdede - sorry for the late reply (To all) I am not sure what you are asking me? If you want an unlocked BIOS, send me a dump of your BIOS region via FPT. Or, do you already know you can flash the stock BIOS modified using the stock package files?


@DvL - yes, sorry for my late reply too! I did not put anything in a list in regards to BIOS settings, I will check now about ram voltage, it may not be in your BIOS is why you don't see it.
I only see memory frequency and nMode support (1T/2T), no voltage for anything. Yes, anyone using this BIOS will be updated for everything but the vBIOS unless they have same chip you do, GOP updates apply to all (Ivy/Sandy)

@klodfor -Thanks for your info and report back too! You can edit UEFI options, like secure boot or Legacy boot, other than that I have no idea what you mean when you say "UEFI Options"
However, you cannot switch graphics, like enable this one and disable that one etc, that will give you black screen.. BIOS is not bricked here, just all display outputs are ran through the Intel chip before hitting outputs, so if you disable that then there is no display signal output.
Additionally, I did not add anything for video chip displays, we were only discussing what all vBIOS is contained in the stock BIOS. For that info, you can extract all these GUID's and inspect each one in hex editor and you'll see the chip ID for each, or look at them directly via hex with UEFITool NE
VBIOS in GUID C98F7B3B-12E8-4D07-8BDC-9581F9F8FE30

Oh, @Lost_N_BIOS , Thanks for the reply but I did open a thread about this later, which you've replied to several times and tried to help me. (it was about a sony computer called sve-1512q1e) Sadly it did not work. The bios had write protection on it and nothing worked. Thanks so much for trying to help and taking a lot of your time on it. I am no longer using that computer since about two weeks ago.

@Kurtisdede - sorry to hear! If you want to try again, link me to that thread, maybe I've learned how to make it possible now vs back then? Never mind, I found it, you didn't reply back about PRR/PRR2 tool.
We can get that sorted still, if that tool fails, then you can use programmer and we can then do whatever you want.
Order a CH341A + SOIC8 Test clip with cable now, and before you forget about ordering it will arrive, price is cheap at slow shipping $7 total for both w/ 3-5 weeks shipping.
If you ordered one back in may it would have arrived long ago

There is an easier way to update to UEFI in an Acer Aspire V3-571G BIOS from an v1.13 to a v2.21 UEFI, its very comprehensively explained here:

How to update to 2.x bios from 1.x bios (applicable for Acer\eMachines\Gateway\Packard Bell)

Link - https://catchtito.blogspot.com/2013/05/h...386653974001456

I have included the above links content below, for your information. The reason I'm including this is because I've done this mod myself and it works perfectly on my V3-571G. But please read the warning below, as I don't take any responsibility for my suggestion and this article, in any way what so ever!

WARNING - Don't try this mod 'IF YOU ARE NOT EXPERIENCED" and you don't have a backup to recover from! Mods like these can wreck your BIOS and make your computer "INTO A BRICK"! ONLY attempt these sorts of mod if you can reprogram the BIOS chip to the OEM BIOS e.g. v1.13 (if this mod does not work) or you can replace the v1.13 chip, if this mod failed! This sorts of BIOS mods should only be attempted by very experienced computer technicians that know how to recover a failed BIOS update and they can recover a bricked computer BIOS chip! A normal person will/can experience lots of problems and this mod is NOT recommended!

For its recent laptop models; Acer (and its subsidiaries) have choose a weird way of delivering BIOS updates. When a model is sold without Windows 8, then it is delivered with v1.xx BIOS which lacks UEFI booting and Secure Boot support. If the same model is sold with Windows 8 and 8.1, then it is delivered with v2.xx BIOS with the option of UEFI booting and Secure Boot.

Problem is a user can't update from v1.xx BIOS to v2.xx BIOS with the downloaded Acer BIOS update. It shows: "Please update to the same type of BIOS e.g. (v1.xx)".

To avoid this detection, we have to hex-edit the following:
Note: This is the best method for Acer Aspire V3-571G with v1.13 BIOS use this method with Hex,editor

Open the bios update application with your favorite hex editor and locate the following:
DisableSecureCapsuleFlash=1
Change it to as follows:
DisableSecureCapsuleFlash=0
Save the changes. You can now update to 2.x using this modded bios. Flash from DOS or Windows.

If you can't find the above string in the bios update application, then we need to take another path.

Extract the application using 7-Zip and try to locate isflash.bin (which is your bios file) & platform.ini. Then open them with hex editor and change like above. Now flash using InsydeFlash.exe.

To overcome all of the checks, we need to edit more:
DisableCompare=0
to
DisableCompare=1
&
SkipSecureBootProtectionCheck=0
to
SkipSecureBootProtectionCheck=1

If you want a SLIC mod, then mod the downloaded bios update using andyp's tool. We have to alter another thing to flash the SLIC modded bios.

Again open the bios update application with your favorite hex editor and locate the following:
[ForceFlash]
ALL=0
Change it as follows:
[ForceFlash]
ALL=1

After updating to 2.x bios, you can safely update to subsequent updates without any modding. Note that you may have to re-install your previous Windows 8 installation after updating from 1.x to 2.x bios.
