Thank you very much.
Let me tell you my experience:
I tried this method but it didn't work out in my case, i got bootloop always. After some research, it seems that i got a problem with the sign of the file, and this is what i did and worked out:
a) be root;
b.) copy with root explorer (or somelike app) from system/framework the file framework-res.apk to the SD;
c) move it to the PC;
d) in the PC, you have to got all the icons you wish to change into a folder;
e) there, open with winrar or 7zip (this is wich i used) the file framework-res (don't rename, just choose 7zip to open that file), go to \res\drawable-hdpi (you browse with 7zip);
f) with Windows Explorer open the folder in wich you have the icons you want to put into framework-res, select all the files, and just drag and drope it into the window within 7zip and where you have open framework-res\res\drawable-hdpi;
g) close the window of winrar o 7zip.
h) copy the file framework-res.apk from PC to SD;
i) there move it with Root Explorer to System and chane permissions to rw-, r--, r-- (you canīt change permissions in SD);
j) then move the file framework-res.apk from system to system/framework
k) reboot and done!!
Advice: altaugh the icons you copy are ready to go from 1% to 1%, it doesn't mean it will work in your device. You have to modify something else that (yet) i don't Know.
See you all.
