i have this firmware R541L7_G_11.00.16R
in the sticky thread, this is placed under the A1200E track. but this has the A1200I or L4 track properties such as portuguese language, no chinese and it's a Quad-band.
I want to flash this device to have chinese menus and inputs. but i'm not sure if i can flash to ANY A1200E TRI-BAND track? or this can only be flashed with the A1200I L4 tracks??
which track is this FW?? 
Linear Mode
