System info:
Model: Acer E-571G
MB Model: A5WAH LA-B991P (Compal)
BIOS chip: W25Q64BV

BIOS chip brand new: W25Q64FV

Note: (I checked this chip's datasheets, this two flash is capable each other, same operation voltage range, just one of is clock frequency is faster then other)


-----------------------------------------------
BIOS Software: Insyde.
WRONG BIOS version: A5WAB 1.32
WRONG model: V3-572G



Hello guys, my computer BIOS version is different model of laptop's. I have some torubles with that, like soundcard and vga drivers, turbo boots and ACPI problems. I'm trying to update bios with manifacturers original bios update software, but i can not. I can update same bios (the wrong one), but when i try to change bios version to original model, Insyde won't let me update because of bios version/model compare etc. i tried tricky methods, and i use HXD to edit Insyde bios files (BDW.fd and platforms.ini) to disable all flashing protections, like "don't compare bios version, Project model protect checking disable, All protection disable" etc, but can not success. when i try to force flash original version, Insyde original DOS kind update screen tell me "Invalid Firmware!!!" error.

So i decided to purchase HW Programmer, i bought CH341A USB programmer and i get new brand W25Q64 SPI. I programmed new flash chip with correct model BIN, that i found on internet. I solder the new chip i just programmed to mainboard, but it doesn'T work. Power led lights up, fan start rotating and few second laters shuts down, and few seconds later automaticly power led on, fan starts again.. and few sec later shuts down. an so on. So i tried couople of BIN files from internet, none of em was working.

(Btw, i don't have second computer to help me)

So then i decide to backup my working but wrong bios BIN and flash it to new chip. I used FPTW.exe to backup my bios file, workingwrong.BIN (6144KB) i programmed this BIN to new chip, i solder it back to mb... But its NOT WORKING either!!!!! ?? (same issue couple seconds power led up, fan rotates and stop, and start again) Btw, after i programmed chip i quick manually check offsetsts and verify it from programmer software.

What i'm doing wrong guys?When i programming 6144KB bios (dump from FPTW.exe ) to 8MByte flash, do i need edit BIN file to correction size or someting? Guys pelase help me, i don't have a hot air gun for soldering... i nearly 15 times solder/desolder my bios chip from motherboard. I'm afraid of i damage my mainboad mistakly : ( .

@nmb - The issue is BIOS is not 6144KB, this is only BIOS region, you can't write that to the chip. Send me your original BIOS Dumped with programmer file, and a copy of the BIOS you want to put on there but can't and I will make a file for you to put on with programmer that will work.
If you never made a backup with programmer before you wrote to BIOS chip with programmer (bad move ) then send me your original FPT dump of the BIOS region, and take your programmer now and dump the BIOS and send me that file
You can do that with old BIOS chip or new, whichever you haven't wrote to with programmer preferably. If you wrote to both chips, it's OK, I can fix on my end using other files, just send me your FPT BIOS region dump.

So what happened originally, how did wrong model BIOS get on system to begin with?

You should have ordered SOIC8 test clip with cable, then you do not have to desolder/solder each time - here is an example on ebay - https://www.ebay.com/itm/382486015977

Also, in my testing, maybe with CH341A software version 1.30-1.34 I think, for W25Q64FV, you need to choose W25Q64BV as the ID (Otherwise it can make errors when dumping or writing to the chip)

Thank you so much for your reply @Lost_N_BIOS !

A couple months ago i need to replace my laptops keybord, when i try to change keyboard i did someting wrong shorctut or someting, my computer is dead. I sent it to repair service, and they told me "your computer IO chip is broken" they say... And they fixed my computer. But they put wrong model bios on my laptop. I dont want to send back my computer to them, i don't like them for another reasons. So that is the history, why my computer has a wrong model bios on it.

I guess you saying, helping me with FTP dump(6144kb) file could be frustrating/annoying for you.

The good news is, actually i never wrote anything to original bios chip (the bios written by repair guy v3-572(wrong model name but working)). I read my original chip with hw programmer and here is the file;

Download =>>>> HWORIGINAL.BIN (8192KB)

Here is the FPT dump ;

Download =>>>> FTPDUMPORIGINAL.BIN (6144KB)


I have this file i downloaded from internet; (i'm thinking to try this one):

Download =>>>> E5-571G-57D9_LA-B991P.BIN (8192KB)

But my laptop is E5-571G-50BW
This bios for ; E5-571G-57D9

I checked difference of two models, only difference is; my laptop has Geforece 820M, Downloaded bios for Geforce 840M, this difference could be a problem?

@Lost_N_BIOS , i edit my mesages and added the files you needed.

Thanks.

@nmb - They may have put in other motherboard instead, so it's possible BIOS is correct one. How much did they charge you?

No problem for me working with 6144MB file, it's just not the complete BIOS is all I meant. So, you have original BIOS chip, not soldered to motherboard, or you dumped it before they worked on it?

Yes, I would not use other version BIOS, especially because of the different vBIOS may be in there, but also because you'll be at same situation you are now (not having correct BIOS in there)
Plus it would have someone else's serial, UUID, and Ethernet LAN MAC ID too. Is your LAN working now (Ethernet one)? Is your serial # correct? This only matters if this is a new system, which you might have to, or still be able to RMA, or if windows activation is failing

So please verify what is the two files above? FPT dump from when, what board, what BIOS. And the programmer dump, before this happened or your original BIOS chip, not touched by the repair guys (So your actual original BIOS)? << If the latter, then problem solved, there is your correct BIOS
Your comments are very confusing. Original BIOS to me means a dump of your full BIOS before the repair guy put on the wrong BIOS, so if you do no have this then you do not have an original BIOS dump. However, if you have a FPT dump, from before they did this, that will work just as well.

@Lost_N_BIOS , i don't have the my laptops Original Bıos file. Because it's gone when repair guy Re-Write bios. 3 montsh ago i never think about backup my bios for no reason you got that?

Yes my computer and bios serial number is different.

Under my laptop plastic case, there is a serial number XXXXXXXXX
when i check bios with HXD serial number is YYYYYYYYY

.

Beucase repair guy wrote wrong bios.

So please verify what is the two files above? FPT dump from when, what board, what BIOS. And the programmer dump, before this happened or your original BIOS chip, not touched by the repair guys (So your actual original BIOS)?


If i have the oldest backup file ( like when i purchased my laptop ) ... If i have it, why i'm here? I jsut write my oldest bakcup to new chip and solder it to MB and everything is done... OF course i idon't have the oldest orginal bios backup. What do you thik? everythime we bought i laptop we desolder bios chip and backup it? Please logic bro.


Like i said, my computer go to repair, and they said BIOS chip broken/burned/fucked up/dead.... How do you asking me to my orginal bios file?

No need to please and logic me bro Yes, you can backup BIOS anytime, without desoldering or using programmer etc, this can be done many ways, often easily with the stock flash tool or built in BIOS flasher. So yes, I assumed at some point you possibly update the BIOS and made a backup before that.
Do you care about keeping current serial and UUID, since you don't have backup I cannot put back original. I can put back original one from stickers though possibly, but those often do not match what's in original BIOS either (UUID does but serial often does not).
If you want that put back, I need images of all the stickers on your motherboard, inside the back case, outside the back case, and on the motherboard be sure to take images of any stickers on the memory slots, and possibly underneath or between the memory slots too if there is split slot.
Or, I can leave all that kind of info as it is now if you want

BIOS currently says A5WAB 1.32 because that is the BIOS version, whatever you saw before was the older BIOS version. If you want some older BIOS version, then pick which here and let me know.

The current BIOS is correct (This is E5-571G BIOS) and latest version for your board, just that guy edited the area to put in serial etc, and put wrong model (This is not even in 572G BIOS, it's BIOS latest version is 1.09)
I can also unlock your BIOS while we do this, so you'll have unlocked (currently hidden from you) power and full advanced options page instead of currently limited one (if you see one at all)

Thanks, I didn't find that on the normal site! I will check it and get back to you
I still need to know what BIOS version you expect/want for E5-571G (A5WAB 1.32 is latest)

I said that about him editing in model info because that is the only place I see 572G, where you manually put in serial and ID info (none of that is in stock BIOS downloads)
That and BIOS version ID is all same as current for 571G as mentioned above, so that's why I said that, before you showed me the 1.32 for 572G (Which I still need to check too, they may use same BIOS which is very common for OEM BIOS = lazy)

Let's say 1.32.. so i don't need to do anything? Becasue you saying it's already correct bios? I don't care UUID or mac ID's.

See my edit above, edited while you were replying. I have not checked this 1.32 you just linked me to, please give me some time to check it all out.

OK sorry, waiting your response.

I found this picture on internet;

https://encrypted-tbn0.gstatic.com/image...gDoDzHVAqU9IL_q

So how this even possible, if stock rom does not have "E5-571" string on them?

I bet, in this picture, probably no body edit this bios file. And it has originally "E5-571G" string in BIN file or someting?

It's OK, just saying I need to check a few things, can't say instantly

Yes, both BIOS are exact same, hex matched byte for byte and he edited in the board specific DMI info (Serial, UUID model etc)


Does your MAC address for Ethernet start with C4 8E 8F, if yes he put that in in same are too (Below what you see here) Might not be that, but just guessing based on it's location, it could be some of the info shown in this image
This is where his edit is, vs stock BIOS, stock on right, your dump on left


That image you linked is DMI info from someone's system. This info is pre-programmed into systems at factory, when someone replaces BIOS they often use stock source and have to manually edit in.
But yes, in general there is places in BIOS with several models I assume, didn't dig that deep here but I assume as much since same BIOS likely used for more than these two models too (This is common with OEM's as I said, some like HP even use same BIOS for 20 different models sometimes)

Today is not my first day at this, I've been editing, modifying, inspecting, fixing, and unlocking BIOS for many many years.

Do you want unlocked BIOS, and your model info corrected?
