Habria que hacer un sysgfx para el Z550...en Se-nse ya los estan haciendo para algunos celulares (W810, w550), hasta hay una "guia" para hacerlo, pero es un proceso muuuy largo, eso si.
Consejos para hacerlo:

OK so the best way I found for finding the functions was this:
(assuming you are porting from W810->W550) go to the function in W810. Instead of trying to search for the actual function's code in W550 using Smelter, go to a different function which calls the function you are looking for. Then search for that function. This way, you have many more options for functions to look for.
For example, if you are looking for "sub_4537D3F4" for example. Lets rename it "sub2" (press "n" when the cursor is on "sub_4537D3F4" to rename). Go into the W810 sysgfx code, and jump to sub2. Then, put the cursor on the title for sub2 and press "x" to show all cross-references. This will show you all the (known) functions which call sub2. Just pick one and search for its code like normal in W550 using Smelter. If you can find it, then you know the original function you were looking for. If you cannot find it, then just pick another function. I hope you understand what I mean.
By the way, you can search for (some) cross-references by searching for the address+1 in little endian. For example, if the start of the function is 0x4537D3F4, then search for F5 D3 37 45.
