yeah I had it done I just wanted to know that if I can change acoustics when I just copy acoustics files in my FW.
Is it secure?
Because if I press "alt+f1" SEFP plugin then there isnt my phone (w580i) support under "boot script" (highest is CID36). I have SEFP 10.00.51 or sth like that.Do I need SEFP or can I just copy those files in the phone with farmanager(jdflasher).
