Okay, ... not worth my time writing to the nand directly, not even opening that old x270 ^^
I get it, if it is a near new machine, ok ... but if i can't use the software flash tools, i give up

My Name is not important and i don't do anything if i don't have to. If i find out who i am, i'll tell ya, maybe, perhaps not, i don't know, stop forcing me, aaaa this pressure, ...

I can finally report, on my X270 the patched UEFI file won't work. After reboot the flashing stops with error secure flash boot something error.

If anyone wonders how to force update: WinFlash64.exe -capload -file $0AR..._PATCHED.FL1

OK, how to update a BIOS on X270? All the update methods tell me i don't have to upgrade, i already got the latest BIOS.

r0iuj44w.exe -> extract, replace the FL1 file with the patched one. It is always the latest BIOS. Did downgrade a few BIOS versions, did try 4 or 5 older BIOS, always the same. If i use the Windows updater, i am always up to date as soon as i use the batched FL1 file. Also if i try the boot stick, it is the same message.

So is there a ways to force update or is the patch not working for X270 at all?

I'm over it, no more try and error...

Thanks for this project!

Creating a bios file for my X270 did work.

Only problem ist, that the bios updater software tells me i already got the latest bios (file) installed. So i can't overwrite the existing bios using the patches file.

What should i do? Change the version inside the file using hex oder bios editors? Is there a way to force overwrite the bios? Thanks
