How do I unlock the phone? I currently have Cm11 on it.
I want to ditch rogers (terrible service) so what do I need to do to unlock it?
side note, when I got the phone it was via future-shop warranty and they gave me a fido version and put my rogers sim in it, did they unlock it then?

Since Fido is really owned by Rogers, your Rogers SIM may work in the phone if it was originally locked to Fido. To check whether it's unlocked or not, try putting in a non-compatible SIM (like Bell or Telus) and see whether it prompts you for an unlock code. If it does, you would need to purchase a code online or request one from the carrier. If it wasn't on Android 4.3 prior to the CM11 installation, you may be able to install stock Android 4.1.1 and free unlock. Either way, whether you are free unlocking or using an unlock code, you have to be on a stock ROM for it work. You can check your phone's settings and see what baseband and bootloader versions you have. This will tell us know whether you should flash stock 4.1.1 or 4.3

Baseband is I747MVLUEMK5 bootloader I have no idea, I just used odin to flash CWM.
I'm open to flashing 4.1 to get a free unlock then going back to CM11

I747MVLUEMK5 is ver. 4.3 and you almost certainly have the 4.3 bootloader as well. With this, unfortunately, you can't downgrade to 4.1.1 where the free unlock option is available as any attempt to do this could brick your phone. You would need to request an unlock code from the carrier, if eligible, or purchase one online. There have been reports also that the unlock codes don't work when you are on a custom ROM so if you buy one online and it doesn't work, you will have to flash stock 4.3.

ok, which carrier would I have to talk to, it was a fido phone as mentioned previously. Also is their a possibility I could downgrade to 4.1, or is it a guaranteed brick?

You would need to contact Fido since it was originally on their network. I'm afraid nobody has yet posted a method to allow you successfully downgrade to 4.1.1 and still preserve the free unlock functionality. You could follow some instructions posted in this forum to downgrade to 4.1.1. However, this wouldn't allow you downgrade the bootloader/modem which is required for the unlock.

I found a way to downgrade from 4.3 to 4.1.1 or 4.0.4 stock. (for Bell).
I bought and used Mobile Odin (available on the play store). Anyhow, it flashes the stock rom and not the old bootloaders. Once you're on 4.1.1 or 4.0.4 the problem is that *#197328640# no longer works. Basically when you type that ServiceMode comes up, but all the options are gone. I believe this is because they locked those features on the new bootloader (which is still on the phone after the Mobile Odin downgrade...)
Unlocking this phone has become a major pain in the ass.

You are quite right. Sam and the networks are winning this time. You can indeed use Mobile Odin to downgrade the system (ROM). However, there hasn't been any reports of a successful downgrade of the bootloader. Therefore, even if you downgrade without bricking the phone, you can't free unlock. Tough but you will need a carrier unlock code.
Hello All,
I got a t-mobile s4 from USA which was paid in full and never activated on any network in USA. I am now trying to use an Airtel Sim Card in India and it shows that its SIM Unlocked. On contacting the T-Mobile support they are saying that they cant provide an unlock code because the device was never activated on their network.
I am stuck because all websites providing unlock codes work on the same precondition that the device was earlier activated in a T-Mobile network. I am also not able to get into service mode and apply the sim unlocking fix as suggested in few posts.
Please provide help and suggest me the options. I am not afraid to shell some more bucks to make it work but i need assurity that the method would work.
Is there a way that i can try which doesnt require t-mobile network at all???
My android version is 4.4.2 and device has been rooted now.
To use service mode to unlock, you need to flash MDL modem first. After unlocking, you should be able to flash the latest modem back retaining the lock.
Have you checked if the region lock away app works?

As far as I know, the service mode unlock disables the carrier check and doesnt require cellular service.
Also, the S4s are also region locked. They get region unlocked when activated and used on the carrier network. So, your phone requires both the sim and region unlock.

Thanks for your response. I am a newbie so just confirming the steps that i need to take to unlock the device:-
a) SInce i am on 4.4.2 with baseband as M919UVUF9B4 i would need to downgrade it to 4.2 stock version using the link you have recommended above.
b) Once i am on the 4.2 version i can then flash MDL modem to sim unlock
c) Then use region lock away tool to region unlock.
d) Upgrade it again to 4.4.2 and use my device freely.
Let me know if i got it right

For the service menu to work, all you need is the MDL modem. You do not need to downgrade everything. You should be able to find a way to flash the modem alone.

Thanks for confirming. However, i am unable to find any thread tutorial which talks about flashing NB4 modem back to MDL on NB4 bootloader. Most of the threads talk about flashing modems which are prior to 4.3 and doesnt serve my purpose as in am on the latest bootloader.
Please help in providing any thread link or steps to perform the flashing.
Thanks Again!

By Sim unlock, do you mean you want to use an AT&T phone on another carrier? If that's what you are looking for, give me a few minutes to test something.

Yes, of course.
But I am fairly new to the note 2 so I don't have much stored up information. I now see a post that indicates that flashing a certain 4.1.1 modem, MJ2 I think, gives the user a service menu where you can change the unlock setting. So now the OP's question makes sense. Only he should have been able to find the same post I did.
In a minute, as soon as my wife lets me borrow her phone, I'm going to test an unlock tool I know about to see if it works on 4.4.2 stock.

The dialer codes that worked on 4.1.1 to unlock the phone via the hidden menu. Does not work on 4.4.2 anymore. And being you took the ota update, there's no way of downgrading you firmware...
Sorry to tell you..
Another way is to contact AT&T by email, about unlocking the phone. Can't remember what the exact name is, but goggle search it. They'll send you the SIM code, if the phone is out of contact!!! Takes about 2-3 days when I did my skyrocket to run on TMO.

At one time, there was a free app on XDA called GalaxSim Unlock. For some reason, the developer pulled the free app download, and the only version then available was the paid version on Play. I have a copy of the free one from before it was pulled, and it works on the Captivate and the Galaxy S II, and some other galaxy phones, not sure which ones. So I tried it tonight on my wife's Note 2 which is running Stock NE5 with TWRP recovery and has the MC3 boot loader. However, the unlock failed, saying unable to read nvdata. So it's apparently a no go on this phone.

That only works if the contract the phone was in was not defaulted, and or you are the original owner of the phone.
re: sim unlock
I recently bought a soft bricked SGH-I317 (stuck on "firmware upgrade encountered and issue"). I tried flashing LJ2 firmware and got it to change to being hung on the "Samsung Note II" logo. I think this is when it changed as I was trying all sorts of flashing trying to get off the "firmware upgrade encountered an issue" screen (also Kies would not recognize that the phone was connected). Tried different recoveries and firmware without making any progress until I flashed the 4.4.2 (I317UCUCNE5) bootloader. The phone booted into Philz recovery after that. I then flashed the stock LJ2 firmware w/ LJ2 modem, sim unlocked the phone and then flashed Skynote Air 4.3 along with the 4.4.2 (NE5) modem. This is the setup that I am using on T-Mobile now with no problems except that the Knox counter is tripped. Hope this helps shed some light on the problem.
I discovered a problem with Skynote 4.3 with the 4.4.2 bootloader. If I try to charge it with the phone turned off, the phone will freeze at the empty battery symbol and requires a battery pull to get the phone to turn on. Everything else seems to work okay.

My sister sell her note 2 to me because she's gonna upgrade to samsung galaxy S5. It was an att and I'm using T-mobile.
I did check the baseband ver and It was i317UCUCNE5 (4.4.2 OTA). the question is it is safe to flash base band ver i317UCALJ2 using ODIN?
Can you do the step by step process and also links of the files and software did you use please? thanks

It's a network unlock, so you are free to use any GSM carrier. You can lock your sim card -- then a pin is required for your phone to connect to your carrier. It's the old skool method to stop unauthorized use, from the days before a lock screen pin.
I bought a SGH-I317M today off someone. It was locked to Bell Canada. I did the dumb thing by letting Kies update the firmware. And as i've read I'm pretty screwed for downgrading it. I tried unlocking it but the hidden menu didn't give me the 4th option in the network lock path. So i tried bunch of things which at one point required me installing Kies for drivers and thats when I i let it slip and update. So now I'm still searching for a method to unlock my phone. I've gotten philstouch recovery on and Skynote working. I just tried flashing the rogers_j2 modem.. hoping this will work.. you think I should just pay one of those sites or a retailer for the sim unlock ccode?

Please let me know if it works. mine is galaxy note 2 4.4.2 NE5 baseband and I've done some research and they said that if you upload your firmware thru OTA there is a possibility that it will soft brick you phone due to unknown security reason.
I'm just waiting for conformation from some one that it's safe to flash J2 modem on a NE5 OTA
in the US, if your phone is more than 6 months old and your contract is in good standing you can ask for the unlock code. I don't know if Canada is similar.
I was going to post the same question about unlocking I317 4.4.2, and found this post which is similar to what I'm looking for so just want to add to pump the question.
It's been a while but I have done unlocking for other At&t models (S3, S4) and learned that later versions don't with the option in hidden menu to unlock, and the work around is to downgrade. However with devices that have OTA updates, it's not possible to downgrade the bootloader.
Is this the same for Note 2 I317? If so, any other method available to unlock this device to use it on other GSM networks? (I just bought one and it's on Kitkat 4.4.2 UCUCNE5, and looking for unlock...)
It's only the modem that needs to be flashed. So whatever bootloader you're on doesn't matter.
I wanted to unlock my phone today. ATT website wouldn't let me do it until my contract was fufilled, so I did some web searching.
Started with 4.4.2 and NE5 baseband. Loaded original baseband via recovery, and used the debug menu to unlock the sim. After that, updated the baseband back to the latest. Tmobile sim seems to be working just fine.

Hello everybody
I have a Samsung S3 SGH-i747M (from Canada) with 4.4.2 and version I747MVLUFNE6 which is locked. It asks for "SIM network unlock PIN".
Is there any way (I don't care for the warranty) to make it work with an other SIM? I am currently in Switzerland.
Thank you very much in advance!
No you'll have to either call the original carrier of the phone and request the code or pay for the unlock code.

The problem is that I don't know at which carrier belonged the phone and one page that I found,that doesn't require the carrier and I think read that is reliable (swiftunlock.com), does not include the i747m in the list.
Any ideas or any other sites?
Any that offer it for the I747M should work. Don't take my word for it though. Ask the vendor first.
Sent from my SAMSUNG-SGH-T999 using Tapatalk
All the sites that i found ask for the carrier which I don't know or to have the phone rooted and have a version lower than 4.1.1 which I don't .
Is there any way to find out at which carrier it belonged?
Or any other reliable solution?
Please... :crying:
Go yo swappa.com and check the imei. I think it shows the original carrier when it does the check.

Once you are on the 4.3 ot 4.4.2 bootloader, you cannot downgrade the bootloader and the 4.1.1 modem will not work on the 4.3 or 4.4.2 bootloader.
You must be on at least the 4.1.1 dialler and modem.

damnit, just saw this. Is there any way to downgrade to unlock the SIM? What about if im on a different ROM?
There is no free way to sim unlock your phone once you have the 4.3 or 4.4.2 bootloader on your phone.
How to know on which bootloader ( bootloader 4.4.2 or 4.3) I am coz I was able to install a custom rom on my SGH-I747M The rom is dirty unicorn android 5.1.1 lolipop rom so Can I downgrade coz if I remember correctly I upgraded from stock 4.1.1 so can I downgrade to stock 4.1.1 by downloading and injecting it via odin is it possible or will it hard brick my phone and can you give me way to confirm what bootloader I have ???
Boot into download mode and look at the screen. If you see anything about knox, it likely the bootloader can't be downgraded to 4.1.1.

Can you guide me that how to know which bootloader do you have i.e. do I have a 4.3 or 4.4.2 bootloader how would I know that? and also I do have a custom dirtyunicorn rom with 5.1.1 so is it possible for me to flash the 4.1.1 stock SGH-I747M rom to it and then unlock it and then again add my current rom and use it???
Download and install the Samsung phone info app from the play store, run it, and look at the last three characters of the bootloader. If it is mk3 or higher, the bootloader can't be downgraded.

Not quite sure where to put this but I have just successfully sim unlocked a samsung galaxy s3 sgh-i747m on 4.4.2 .This is only prelimary but upon unlocking and inserting a Public Mobile sim I was able to text on a Canadian Rogers S3. No further testing has been done. I first rooted the phone using Kingoroot and then downloaded the phoneinfo app from play store. I then used the app to get to service menu.At first service menu is blank but I used menu ,then key input Q, then back, then key input 0000,then back and then service menu appears. Now I am doing this from memory and no longer have the phone or another one at the moment to confirm this and will update this as soon as I can. But to the best of my knowledge I first went to UMTS(1) ,thenDEBUG(1), then Phone Control(?), then Network Lock.. Perso-SHA256 was on(1) I set it to off (0). I then backed out of the menu and shut down phone.I inserted PM SIM in phone and booted up .Phone didnt ask for unlock code and shortly I had texting service with Public Mobile. I dont have voice or data to check those but cant seewhy they wouldnt work. Anyway can someone confirm this working.My steps may not be exact but if it worked for me it should work for others.
Sorry if its been asked, answered and in the wrong spot but I'm on fob6 5.0 and I want to downgrade to 4.4.2 so I can flash darthstaker. Can I do this? And if so can someone send me a link to a,mediafire or dropbox for the 4.4.2 Odin firmware files please?

You should probably ask in the questions section. You can find official firmware in sammobile or updato (Google search)
Does the custom ROM need a kk bootloader and modem?

Yea it does. I also need to downgrade to sum unlock since tmo is screwing me around.
Downgrading will allow network unlocking using a free method?
As far as I recall, there is no way to force a bootloader downgrade from mm to kk.

I'm not on MM I'm on LP 5.0.2
My mistake, I meant to say LP, not mm as I know the note 3 never received mm from Samsung.

How do I network unlock then? Do I need just the baseband or how do I go about it? Tmo is lying and jacking me around and I'm poor n can't afford a unlock that costs
Flashing different bootloaders or modems will not sim unlock the phone. The cheapest method I know of to unlock would be to buy an unlock code via eBay.

What I'm asking is can I flash the baseband for 4.4.2 and do the service menu unlock as I would if on stock 4.4.2?
I have never heard of a service menu unlock method for the note 3. Do you have a link?

That's my plan for the unlock is the service menu unlock. Can you please get me the KK modem/baseband to perform it please? Or a working link to the modems foe n900t for kk?
Do you have a link to the service menu unlock method? I've never heard of one.
There was a service menu unlock method for the s3 and possibly the s4 but never heard of one for the note 3.
The stock kk modem would be found in the kk stock ROM which can be downloaded from Sammobile.com.
Before flashing anything, I would confirm that such an unlock method works. Playing around with the service menu can wreak havoc with a phone.

I can't use sammobile. I don't have the patience to sit n sign up for it plus out takes,ungodly time,to download anything lol. Would,you or anyone have the files needed on deck? Say Android host sites or a,Google drive maybe?
You could search the general threads for the files you need. Not sure if they are there, but the 4.4.2 service menu may need a 4.4.2 bootloader? If the phone had a 5.0 bootloader, you may not be able to downgrade the bootloader.
How do you use the service menu to network unlock?
I never had a T-Mobile note 3, only the Canadian note 3.

*#0011# I'm guessing. I need the mj2 baseband or before and only the baseband. I have a s8 plus and a s5 but I needs this unlocked so I can resell for more
Are you aware of anyone who successfully unlocked using the service menu? If there was such a method, it probably would have been posted on XDA.

I've only seen and done it myself on a Samsung S II (hercules) on stock firmware and read that it was available on other similar Samsung phones but I never tried it on the Note 3 as I thought Samsung eliminated that option (even though it was pretty hidden)
The option was also available for the s3 on 4.1.1 but it has never been done with any note 3 on any version of the stock ROM afaik.
