not enough time.
sory.
you can get my firmware and just disamble it if you are in a hury.
you need 720p.sh 1080p.sh from xbin folder, advanced_hfw from app folder.
create preinstall folder in root directory and put there 720p.img(720p kernel) and 1080p.img
i will post all files as soon as i get more free time.

I already did all you said and more , In addition to the files you mentioned i did the following:
i included also b720p.img , b1080p.img
which i beleive the boot images , buildHD.prop , buildNORMAL.prop which
Are the build properties for 1080p and 720p respectively , switchres.sh
Which the script that decides between 720p.sh and 1080p.sh
I also modified install.sh in the /system/bin folder
which installs switchres.sh , 720p.sh , 1080p.sh scripts (correct me if i am wrong in this part)
And finally modified init.rc in the boot to call install.sh during startup

But it doesn't work , Advanced should shows up in my settings but nothing happened
I can see that the advanced_hfw is installed as a system application but it doesn't exist
In the settings menu or anywhere else , so i am unable to run it.

i don't want to disturb you or waste your time , you don't have to write
A how to nor post the any files because as you can see i am very close but
something very small is missing , all i ask is that you tell me very briefly what it is.

i forgot something to;p
i edited the app so it will not show in app drawer.
use settings.apk from my firmware and you are good

Thanks very much i will try that

[opengl1971]

Now i can confirm that it worked very well , thanks very much lewy2004
One last question , is it possible to change the HDMI Output resolution also ?
I thought of changing it in buildNORMAL.prop and buildHD.prop.

So is there a way to change it in these build.prop files ?

[lewy20041]

probably no as its hardcoded in kernel:"

[opengl1971]

But when you change it manually it stays the same , so there must be some place this setting
Is saved right ?

[lewy20041]

good point
i will try to figure this out and post if i find something ok

[opengl1971]

Thanks very much , i really appreciate it.

The following syntax seems to do it:
echo "1920x1080p-60" > /sys/devices/virtual/display/display0.HDMI/mode

But it doesn't last between reboots and it is not reflected in the settings application
Meaning that when you change the HDMI resolution by this command say from 720p to 1080p
It works and HDMI resolution switches to 1080p but when you check the settings application
You will find it still indicates 720p despite the fact that it is 1080p.

The weird thing is that if you change the resolution manually you will find that
/sys/devices/virtual/display/display0.HDMI/mode has changed correctly which is weired

I think the only meaning of this is the setting app saves the resolution data in 2 places , one place
isresponsible to execute the change which is/sys/devices/virtual/display/display0.HDMI/mode
and another place some where else to save the data which the settings app reads the data from.

I think to do a permanent resolution change and to make the settings app shows the correct
Resolution we have to find this other place.

If this is windows i would write a C++ app to intercept any disk write system APIs and dump its
Content to analyze where the Api is going to write the data , but my android knowledge is next
To none
