Dears,
I buy a I747 and bring back to my country to use so I already unlocked it (using N3X cable)
Now I want to flash new rom such as CM10 so do I need to unlock my phone again after upgrade ?
Thank you
You shouldn't have too. Once unlocked, it should remain unlocked. I've flashed every single ROM so far and my unlock has remained in tact.

Is there a way to root without unlocking bootloader? Tried looking around find only Verizon topics and different replies on att.
Also is there a stock image to reflash if needed to get ota updates if needed?

Ok thanks how do I reflash the att stock image if I wanted that

once you have the bootloader unlocked and clockwork recovery installed you can make a complete backup of your phone in the recovery mode.
Thats what i did before i flashed a new rom. The stock att rom is not available here so you need to make a backup as far as i know
And ok I dnot want to unlock so I was going to go the route of flashing the other region firmware. But if I dint have the stock att firmware to go back to I dint want to do that. Guess I will have to wait to see if someone can figure out root without unlock. Thanks for the help though I understand now.

I had att but flashed to r800a 2.3.2 using wontanserver.com (its free just got to register) then used gingerbreak and updated OTA to 2.3.3 with bootloader locked. R800a is like att but no att bloatware.

Right but if you ever wanted to go back to r800at stock firmware is there a way?

I was wondering this myself, since I too have an AT&T play, running the 800a firmware on GB. I've been having some issues with it though. Is it possible to go back to AT&T stock?
No unless you unlock bootloader and find someone who made a back up of the att rom.
What problems are you having?

blatz729 is completely right
Just don't loose the unlock code, after flashing a new custom rom just apply the code to the phone again and your good to go!
Extra: Your very lucky to get your phone unlocked. Congrats!
The phone shouldn't become unlocked, no matter what. If it does, however, the unlock code you recieved will work again as its hardware, not software based.

So i talked with T-Mobile couple days ago and asked them for a Unlocking Code for my T989 and i just got it today, I restarted the phone using a Different SimCard and it doesn't prompt me for Unlocking the Device this could be cause of the Rom i have currently installed which is the XTREMEPERIA#5, Is there any Rom out there i could use to Unlock my Device without Restoring it to Stock Version using this Guide

You just need to use stock to unlock than your device will be permanently unlocked.You can use any roms after that

Once your phone is UNLOCKED you cannot remove the unlock by
flashing roms and rooting or unrooting the phone.
You can flash any rom you like and or root or unroot your phone and it will remain UNLOCKED.
A unlocked or locked phone has nothing to do with rooting or flashing roms.
Good luck!
Thank you for the info will be rooting tonight

This might be a stupid question but I want to ask anyway. I just bought a T-Mobile Note 2 and am awaiting a sim unlock code (I know I can downgrade to 4.1.1 and unlock it via the hidden call menu but at this time I am not opting to do that). I flashed the 4.1.2 Root Injected Stock Rom. My question is, (which maybe I should have asked before hand) Will I be able to use the sim unlock code that T-Mobile provides me with despite being on the root injected 4.1.2 stock rom? Thanks!
No issues, I did it and it worked for me.

I unlocked it using the code provided by t-mobile.

Hey guys, just a heads up, if you are running 4.1.2 there is NO WAY to unlock your T-Mobile Note 2 without downgrading to 4.1.1 as far as I can tell. Even if you receive an official code from T-Mobile it will not work because when Samsung patched the security hole in 4.1.1 which allowed people to unlock their device manually they (accidentally) blocked any way of sim network unlocking. You can read all the complaints on the t-mobile website forums. So, with that being said you have to downgrade to 4.1.1 with Odin and access the hidden menu from the dialer. Just search the threads and you will find easy instructions.
NOTE: When you downgrade to 4.1.1 make sure you do a factory reset from recovery before you flash via Odin. After you flash the ROM your phone MIGHT go into a bootloop/hang on Samsung logo. Just go back into recovery and factory reset again. Give your phone about 4-5 minutes to boot up, just sit it on the table.
YMMV.
Thanks a lot for the tips but I downgraded before and it didn't work.
I still have a backup of the rooted 4.1.1 stock ROM. That's how I downgraded and tried to unlock but nothing happened.
Do u think I did something wrong or is there another way?
