Try these instructions:

If you don't see a PHLASH.INI file in the same directory as the flashing program, then create one and add the line "Advanced=1".
Let me know if this works for you or you run into any problems.
Did you uncheck "Flash only if BIOS version is newer than system" under Advanced Settings? Your Advanced settings should look like the ones in the picture attached to this post. Even if you did uncheck it, please verify that it stayed unchecked.
p.s.
Its obviously reading YOUR file as the same version !
We're going to try using the DOS utility called Phlash this time. Follow this guide by Ahmed Hossam:

Format the drive as FAT. Heads up that formatting will delete all data on the drive.
Let me know if you still encounter an error. If you do, I may have to see if I can do some reverse engineering to get rid of the troublesome error... There is an older version somewhere of phlash16 (the utility you will be testing) that doesn't contain the version check, but I have no idea which one - and there are *many* versions.
I will need to know the exact error with its exact wording if you get one.
Tried the whole shebang, got the attached error message...
Alright, let's use Rufus to install FreeDOS onto the flashdrive.
Please follow the steps under the "Creating a Bootable DOS Stick in Windows" heading here:

After this, place the phlash16 utility and the modified BIOS image on the root directory of the flashdrive.
Boot into the flashdrive and run "PHLASH16 /S /X /FORCE".
Let me know how this goes.
Thanks. But my laptop buzzed through the speakers and came up with this error message...
What is the name of the modified BIOS image that you put on the flashdrive? Is it still "TZ1H_290_mod.WPH"? If so, try entering the command "PHLASH16 /S /X /FORCE TZ1H_290_mod.WPH". Alternatively, you could rename TZ1H_290_mod.WPH to BIOS.WPH and just run the "PHLASH16 /S /X /FORCE" command since "BIOS.WPH" is the default file name the program looks for. And just to check all the boxes, make sure that the modified BIOS image is in the root/top directory of the flashdrive so that the phlash16 program can find it.
