[Q] Best Unlock Method AT&T Note 2 (4.1.2) - AT&T Samsung Galaxy Note II

First of I must say.....I am not that advanced in doing these types of things!
I have a AT&T Note 2 that is running 4.1.2 Android. I have read many threads about unlocking and most say I have to downgrade to Android version 4.1.1, is this true? If so does anyone have EASY instructions for doing this from a MAC?
Then I read in other threads where people say.....DO NOT downgrade back to 4.1.1 you are asking for problems. Instead have it rooted?
I am lost and just need a honest answer and help getting it done, before I leave the country and need it unlocked for use with international SIM cards.
Can anyone help walk me through this??
Thanks in Advance,
Greg

You only need to revert the modem to 4.1.1 (i.e. ucalj2 for att) then follow this guide...
http://forum.xda-developers.com/showthread.php?t=2176719
You can then flash back to the modem you are currently running. Search the forum to find cwm flashables for both.
Depending on where you are at in your contact, you can also request an unlock code from your carrier.

[Q] Bell Galaxy S3 i747m - Original Rom

Hello there,
I am very new with Android phones and I have some questions if someone can answer me please.
I have done hard reset my Galaxy S3 couple days ago and I was trying to run "Video Hub".
"Video Hub" was giving me an error message that is "Device authorisation is failed"
Honestly, I do not mind that this app does not work but it really challenge me that the "Hard Reset" does not really clear all the information on my phone.
Here is my question.
1. Is there a way to re-format or re-install android OS on my phone? (something like returning to the beginnig of my phone when I bought it)
2. I have two ROMs (one is the Bell Jelly Bean ORIGINAL rom and Bell Jelly Bean ROOTED rom), using these ROM, can I re-install android OS without voiding warranty?
3. if my phone get "Bricked", using the Bell Jelly Bean ORIGINAL rom, can I unbrick my phone? (I saw some post that I need CWM? do I need to get additional file to download?)
Could please someone explain me? I am ready to learn new things but I need some basic knowledge. please help me...
Thanks, guys!
Device authorisation is failed
here is the link to earlier official firmware http://forum.xda-developers.com/showthread.php?t=1968625 download the appropriate files drivers,and flashing software, no need to root no cmw you will be able to back to orgional stuff.

Re.
first, thank you so much for replying my post.
but I want to make sure what I understand from your reply.
So do you mean, if I just flash the original stock ROM, it will remove all the previous information without voiding warranty??
Thank,

Come on man this is simple. you shouldn't be flashing if you don't have a failsafe anyways. Look up the correct image/country/carrier for your phone and that is your backup. If you can get to Odin you can always get back to square zero
Thanks for the replay.
I don't know why I am worried so much.
Before it gets wrong, I just wanted to be ready.
I will try that when I get home today.
thanks, guys!

Hi, I need help please, here is question:
I bught my i747m a week ago, im from mexico and Telcel is the local carrier, Can something go wrong if a Install any official stock rom from another country?
I am using a Bell Galaxy S3 SGH i747M with baseband MVLUFNH2 looking to unlock this phone. I am currently under the impression I have to revert to jellybean to do this. Is this correct and if not can someone please point me in a definitive direction?
Once the phone is on 4.3 or newer bootloader, the only way to unlock the phone would be to purchase an unlock code.
I know that the regionlockaway app can be used for Bell/Rogers/Telus s4 but I haven't seen any method for the s3.

Ok Your post is confusing me in that it sounds like the second sentence hints that the regionlockapp can unlock a bell/rogers/telus phones for free even if on 4.3 for S4?
For the s4 from Bell/Telus/Rogers (sgh-i337m), you need to downgrade to stock 4.4.2, flash the stock 4.2.2 modem, root, run regionlockaway app, reflash stock 4.4.2 or 5.01 ROM. The s4 should now be permanently sim unlocked.
With the s3, certain modem/bootloader combinations can brick the phone so I don't know if regionlockaway will work on the s3 sgh-i747m.
God this is a nightmare i figured such an old phone would be easy to root and unlock and every damn lead I follow leads to a dead end.
I searched high and low for a free unlock method. I finally gave up because I did not want to take a chance and brick my phone by trying to downgrade the modem, rooting, and installing regionlockaway. Unlock code was $15.
I'm not too great with this stuff anymore but why can't a good coder edit the files within and unlock it simply by flashing the edited file? In the end its all code right?
I'm on 4.4.2 running an old cyanogen nightly. I purchased an unlock code and when I type it in it says Network Unlock Request Unsuccessful. Any Ideas?
You need to be running a stock dialler in order to enter the unlock code which means you need to flash back to stock or flash a custom rom built from a stock rom.
I did manage to sim-unlock an I747M with 4.3 version of Android (build JSS15J.I747MVLUEMK5) -- or, at least, it doesn't show the "enter network unlock code" anymore... via ServiceMenu, perso SHA off, and NV rebuild/restore; procedure is described elsewhere on the forum. No such luck with 4.4.2 (tried downgrading -- no go)
Now -- an assumption: since there are various remote USB unlocking services on-line, claiming success remotely unlocking the I747M with 4.4.2, someone -- and likely more than one -- here on XDA knows how this is done. I've been trying to piece together the procedure for it, going through pages and pages of discussions, not finding much.
I'd like to appeal to those who know -- please share the knowledge, or at least point in the right direction those of us who want the DIY solution...
cheers
You sim unlocked the i747m that was running stock 4.3 using a hidden menu? That would be great news. Did you try inserting a sim card from another carrier and connect to their network?

I tried inserting a few non-registered/old SIMs from a variety of carriers (incl. european); the phone did not produce "Network lock code" prompt, and just reported "unregistered SIM", just like a _known_ (i.e., tested in the field) SIM-unlocked phone I have.
If you are able to get a sim to try connecting to a network, other than the original carrier, let us know. Thanks.

US Cellular GS3 (SCH-R530U) 4.1.2 Rooting??

Hey everyone,
I have rooted my GS3 prior to US Cellular's update to android 4.1.2, but after the update, every rooting method I have tried has failed. I almost bricked my phone the other day attempting to use a toolkit.... It tripped teh flash counter apparently and my device status was "Modified" instead of normal. I downloaded the Samsung update tool for the USCC GS3, and did a manual update after i discovered that my prior rooting attempt tripped the flash counter, disabled my Wifi, and caused me to be unable to download an OTA update.
The question is this...... what rooting method shoudl I be using for the USCC Galaxy S3, running 4.1.2? I'd love to be able to block ads again....... and I'd like to stay with the base OS if possible (not flashing it atm)'
Thanks in advance!
Questions and help issues go in Q&A

http://www.epiccm.org/2012/06/cwm-recovery-on-all-sgs3-lte-variants.html
Using that method should would, oldest method and always proves true. Like always, you're responsible for everything.
Tripping the flash counter doesn't matter... I have never had USC reject warranty service, and I don't use any counter reset tools.
Unfortunately, XDA isn't the best place to find support for USC phones... Do a Google search for TeamUSCellular and go there for detailed step by step guides.
Then, look carefully at some of the ROMs here on XDA... Several of the ones that use Aroma support multiple carriers.

Root build 4.1.2?
Newb here,
Has anyone had any success in rooting the US Cellular SCH-R530 with build 4.1.2? I donated to the Samsung Galaxy S3 Toolkit cause but after an auto update the most recent build listed for US Cellular is still 4.1.1.
Thanks!

No I didn't 'ready' it but I did read it and that post was from a week ago. So I am following up as a lot can happen in 1 week. Either way, TeamUSCellular does not have anything on it at all. But thanks for all your help. I am now regretting the fact that I donated to the development of the toolkit. I guess if this isn't a good place to find help on US Cellular phones then there shouldn't be any US Cellular phones in the toolkit, but yet there is....hmmmm.

I think you need to look a little closer.
Go to Forum, go to the SG3 Development forum, go to SG3 Guides & Tutorials, then the 5th topic down is what you want (How To Root Jelly Bean LK5 & MB1).
It takes you step by step and even provides links to the files you need.
I just used this last week on a friend phone and it worked fine.

idk if its international or not it was bought in the US via Tmobile store
I have watched about 4 videos from this site but they all say different things and many of them are unclear
some vids say tmobile rooting but use sprint files to do so another was simply unclear
I found this thread http://forum.xda-developers.com/showthread.php?t=1771687
but I am unsure whether it supports my US bought s3
it also says its image is based off TMO T999UVDMD5 but i have the JZO54K. T999UVDMD5
just need some clarification whether it is ok for me to follow this guide or if I need another image or a diff guide
also to know if I need to take any extra steps
I want a simple root so I can run apps that otherwise I could not
I dont know much about rooting

Thanks for any help

T-Mobile Image
April 2013 - 4.1.2 JellyBean
Note: This is based off of the stock image TMO T999UVDMD5
Perm Mirror: Download - root66_TMO_T999UVDMD5.7z
Flash that one with Odin.
The best possible thing you can do before doing anything, is to read the sticky threads.
The beginning part of the build is never referred to, so you don't need to worry about it. Just go from where is has T999********.
Stay in this part of the forum. Flashing anything from anywhere but here could cause you problems or a brick.
The thread you linked is imo the best choice for rooting. There are several options, but I like root66 best.
Start with the stickies (yes including forum rules), then search for any questions you still have. I can almost guarantee 90% of any questions you come up with has been covered before.
ALWAYS read the entire OP of anything you want to flash!
Just to get you started though, use the root66 UVDMD5 firmware to root.
This is not the international forum. You are in the right place.
In my signature, you will find just about everything you need to get going.
Good luck and welcome!

Now that you're rooted, make a backup with whatever recovery you installed(TWRP or CWM).
This will be your backup incase you flash something and your device becomes unstable.

[Q] Note 2 i317/i317m Bootloader Locked or Unlocked

So I'm new to this xda forum thing and I just have a simple question regarding my note 2 sgh-i317m from rogers. I'm looking to root and flash the latest cyanogenmod to my phone but I've read that to root your phone you must have an unlocked bootloader. So I don't know if my note 2's bootloader is unlocked, whether its already unlocked by rogers when i received it or how to check if it is or isn't. I've looked around all over for an answer to my question and all I've found is a non legit article about how most Canadian note 2's are already unlocked. I don't want to go ahead with rooting my phone and having it brick because my bootloader is locked so I would appreciate the help! Thanks in advance!
For rooting purposes start HERE:
http://forum.xda-developers.com/showthread.php?p=33854391
For recovery I use TWRP HERE:
http://forum.xda-developers.com/showthread.php?p=33867032
Rom I'm running as my daily driver
Found HERE:
http://forum.xda-developers.com/showthread.php?p=36575063
For Rom's and info go to the ONE STOP SHOP thread! Think you should READ up on flashing Rom's, making back ups, modem's, just Android in general!!!
If you haven't done it before it's always the best policy to read as MUCH info as you can. Which in turn Wil save you in the END...

Galaxy Note 2 Help please

Hello everyone!
I thought I bought a unlocked phone from Fry's electronics! but it ended up as a AT&T SGH-i317 Galaxy note 2
I tried to take it back but they said the only way it to buy an international phone??
what I got is a Galaxy note 2 SGH-i317 AT&T android version 4.1.2
can anyone tell me the very best way to root this phone and the best custom recovery app for this phone and also
is there a stable or should I say the best reliable rom to use for this phone
I can see all the post for all this for this phone but I wish to only do this once
and not like all the apps I did on my old htc evo 4g
Thanks for all the help and advice
Bill
Rooting
yes I have gone through and have read all the post I can about rooting this Samsung Galaxy note 2 SGH-i317
I see two ways of rooting
1 using the program Odin
2 ExynosAbuse-v1.40
3 then there is this one here http://forums.androidcentral.com/sa...s/247891-t-guide-how-root-unroot-t-note2.html
I am sure there are other way I have seen on the web. But then we read about this knox thing about rooting
then ExynosAbuse says that way is the most secure way, safe from hackers
does this mean the other ways of rooting open your phone up for hackers to get in??
I am SORRY I can not write code I am not a computer or cell phone geek (brainy person in the computer world)
but I do not wish to brick, mess up my new phone!
So I am here to ask the question what is the best way to root and why
my aim is to get rid of the AT&T stuff I also would like to install a custom recovery / boot loader and a stable custom rom
on my Galaxy note 2! like I had with my old phone htc evo 4g
but from what I have read on the web it seem the Samsung phones have issues with rooting then the htc evo 4g did
so my I politely ask for help and information on this rooting of the Galaxy Note 2
to me so far number 3 from about seems good but then for safety I got to go number 2 from above??
HELP PLEASE
Bill
Root is done
well I rooted my phone as I have gotten no advice from here allot of peek-a-boos I see
I tried the Odin way but I kept getting a c++ error from both of my computers and the program had to be shut down?? oh well
then I tried the Skipsoft toolkit and that got it done
now is there any one out here that is a rom installing maniac?? Could you tell me please what rom out there that is fully functional and
stable like the stock rom on this Samsung galaxy not 2 SGH-i317 is!
my reason is to have a clean system on my phone with no AT&T gunk while I am on T mobile service
is there any help or advice for this or am I posting to dead air
Bill
Use CF auto root....found in the development section under the same name...
Verify that you are using root for the 4.1.2 firmware..and done...
Don't use those odd root methods or you'll have issues...
CF auto root is the root standard for this device...
Once rooted...you will want to flash a custom recovery and make a full nandroid backup of the device...(I use TWRP recovery...but you can use CWM as well without issue)
Both recoveries are also available in the development section in their respective threads ...
Store that backup on PC so you don't lose it to bad sd cards or deletion...
And do "NOT" upgrade your bootloader....or you'll never be able to go back to pure stock later if desired...
Read read read...and go slowly for comprehension...
Happy flashing....g
