Could you please help with providing a modified BIOS that I can flash on ASUS ZenBook Pro N501JW that is using the HM87 Intel Express chipset?

I have tried modifying the latest BISO N501JWAS.212 available from ASUS website, using the tools from this website (MMTool and UEFITool), but both times I am getting the error message that the modified BIOS file is not the same size.

When I try using fptw.exe program to flash the modified BIOS, I get the Error 26: The host CPU does not have read access to the target flash area.

Attaching the FD.bin file created using fptw.exe

Your help is greatly appreciated.

First of all if u want to flash a MOD bios, the OEM (Asus) security issues have to be unlock for any kind of flash, besides a CH341 programmer...that u may still need.
Unlock it first, make a dump them with FPT, edit the dump file and then u can flash it back again by FPT.

As always theres a risk of breaking the system, that all users should be aware of.

Yes MeatWar said right, you can use Intel Fpt tool only finding ME version and finding the CSME according to it here :

Then there are the eeprom protect issues and the EFI IFR doesn't show notinng so USB CH341a + Climp Pomona.
