is the error insyde secureflash invalid firmware image many persons with acer v 2 bios get this error you can bypass this error if you flash it through the recovery procedure with a usb drive

[stric9]

Yes that's the error.. I'll try the USB flash

[Republic Of Gamers]

The insyde bios recovery steps are :-
1.Format a Fat/Fat 16 usb drive
2.put your bios file(iscflash.bin/.fd inside the usb drive
3.Shut down your notebook
4.Remove battery,usb peripherals,pendrives,Ac Adapter
5.press and hold power button for 10 seconds(Ac adapter /charger unplugged)
6.Hold Fn+Esc while holding Fn+Esc insert usb drive which contains your bios file
7.Still keep holding Fn+Esc now press the power button while holding Fn+Esc Fan will get fast and after a few minutes bios will be flashed the screen will remain black while flashing bios

@Republic of Gamers The invlid flash error is some form of bios protection used in new Acer bios. A popular method to bypass it is to use Intel's flash programmign tool, fptw, to flash the modded rom since the check happens by InsydeFlash.exe. Fptw expects the bios rom to contains all the unique settings, like a serial number, UUID, etc, and the rom from the installer doesn't have this so the sizes wont match. So you have modify the rom that's dumped with fptw, then reflash that rom

Now I'm confused on which way to go.....do I use the Intel flash tool or go with USB method ?

Hello!
Donovan I saw that many persons are getting this error but some of them bypass the error through the recovery method but some cant they just hear some beeps any the notebook boots normally but yesterday I bought a new acer notebook and I modded its bios and flashed it using insyde flash and I also got the error invalid firmware image and I tried the recovery procedure but it just beeped at me 4 times and booted normal so I heard of a way to change the hidden values without modding it using fptw tool but I dont know how to flash a modded bios with this tool Can you please give me some advice on using intel flash programming tool(fptw tool) to flash a modified bios so that I can get some help and also for helping others

For some reason, I slightly suspect you of being Eternal Mangekyou's third profile. I'm almost certain your not, but your similar to him in some ways. Don't take this to seriously though, I'm just thinking out loud

Anyhow, Intel's flash programming tool is capable to dumping your entire bios chip, which consists of several regions. These regions are things like the flash descriptor, ME firmware, GPE, BIOS, etc. Usually the flash descriptor sets it so that you only have read/write access to the bios region of the chip. There are different leaked versions of this utility that support different Intel chipsets. So you'll need to get the version that supports your computer chipset. Also I think it was Svl7 who was the first to discover that using fptw to flash the bios would bypass the invalid bios error on Acer computers.

So here's how to dump just the bios part:

Code:

fptw.exe -d output.bin -BIOS

You'll notice that the bios region contains things like the EFI global variables and serial numbers. These things aren't in the bios directly from the Acer's bios update. You can then modify the bios dump with any method you want, then to flash it:

Code:

fptw.exe -f output.bin -BIOS

Then I also encourage people to verify the flash just to make sure everything went right:

Code:

fptw.exe -VERIFY output.bin -BIOS

However a better goal would be to find out where the validation check is in the official installer is so that we won't have to rely on leaked tools

I am not Eternal Mangekyou I have seen his posts and he was only asking for donations and he didn't successfully modded a single bios but why do you think I am Eternal Mangekyou. So I used this tool and it generates a output.bin so do i have to modify the dump the same way as I modded bios and I saw in the download page of fptw that it.overites the bios region without warning even if something is wrong so can notebooks be recovered if something goes wrong while using fptw
