I'm getting a new note 3 4g withing few days hopefully from du carrier here in UAE. The phone is sim locked to du and mostly is sm-n9005. My question is how can i know if the bootloader is locked? and if its unlocked , can i root the phone even if the sim card is locked to the carrier??
1. DO NOT LET the phone auto-update or security-update.
2. If it is a N9005 check (with *#1234# ) your AP, CP and CSC
3. If you have AP <= MJ3 then you can very likely root with Universal Root De La Vega (URDLV); you can then update to MJ7 using Mobile Odin Pro (MOP) and keep root and knox 0x0.
Search around for more details on the specific thread on URDLV and URDLV+MOP.
That being said - if the phone is ALSO carrier-locked you might also need to unlock with a special unlock code (at this point I would think that removing the carrier-lock should be step 1.5 above but I don't have much experience in carrier-unlocking Note 3 since mine was "EU unlocked" version).
