Hello.

As I saw in the first message, this method is only for 77 series chipsets. I have V3-371 laptop with Broadwell and 97 series of chipset. Can this method be used for flashing modified BIOS to my laptop?

Thank you.

It is possible to flash SecureTiano Phoenix BIOS? I have a Lenovo G580. I upgraded from BIOS ver. 62CN41WW to 62CN97WW and now i want to flash it to remove the whitelist check.

When you use the prr2.exe are there any commands that you need to put with it? or just run it?

I would ask to Svl7 if there are possibilities to bypass the Error 280 as I found only a way using the Sleep Bug (every credits go to "Vodek" as during my

experiment He does the result file after the Sleeping Laptop and voilà I saw the BUG and the Trick !

It works on Insyde and Intel CPU, not for all Bioses (may be then It is been corrected), but a lot of times is good !

Many thanks for all efforts and tools !

Regards

prr, the original isn't stable, what improvements are there with prr2, it is more compatible with a wider variety of chipsets?

Also, if I am working on a board that uses an AMD chipset, this won't work with AMD at all, correct, why is that? Are UEFI's exclusive to Intel, since Intel created it in response to Microsoft's requirement?

Intel invented EFI, while UEFI came out of a consortium agreement between OEMs, hence the U [unified].

Interesting. I may have to try that on a Haswell Alienware with Secure Flash cancer since the prr2 tool doesn't work due to write-protected ranges. Would be sweet if using sleep and waking somehow temporarily defeats the write protection long enough to flash an unsigned BIOS.bin with all menus exposed.

It's sad that a talented hacker (or a thief with access to InsydeH20 tools) hasn't found a way to remove the Secure Flash protection permanently. Would be so nice to see an end brought to the use of NVRAM trash, too.

If a modder had the tools then the modder could make their own signed BIOS. A modded BIOS would mean 900m gpu compatibility and possibly unlocked fan tables.
