i've got an n73 RM-133 v3.0638.0.0.1 with 3 australia. i wanna upgrade my firmware. so i've got a few questions. it would be very helpful if someone could answer them:
1. what is the difference between ME, IE and normal editions?
2. i'm not a music buff. i'd rather pass ME, go for IE or normal, which one of those two?
3. could not find any product code for n73 australia(ME available, no IE or normal), does anyone have product code for IE or normal?
4. is NSS and NSU enough for update, or i need some other software?
5. can i put my old CODE back after FW update(to NOT void warranty)?
6. an updated guide would be helpful. the available ones mention gsmmagic,phoenix...etc. very conflicting info.
cheers 🙄
