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.

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

@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!!

@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

All done!! [thumbs-up]

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!

Well, I'm glad to see your bios got sorted out.. What settings did you get unlocked?

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.

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

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

please, who can help me
my laptop is acer travelmate 4750. it donot surport uefi, can someone help me to mod the bios? the bios file adress: https://global-download.acer.com/GDFiles...ACER&SC=CHINA_1

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.

I have a strange problem with my Acer V3-571G laptop. I need to reverse RAM slots so the system can boot.
So I decided to update my bios to the last possible update and unlock version. Can anyone provide me a bios update or a detailed structure to update it and its component?

ha my English is not very well
may i ask anyone for acer v3-571g 1.13 .fd ?
i have problem to get it
i cant even open it in my new computer
