[Q] How to unlock SGH-i747m

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.

How to sim unlock the trac phone sgh-s970g galaxy s4...and possibly others

Ok so this is still a work in progress but it works, and lte works on my att and tmobile sims. Ill post as many screen shots and be detailed as I possibly can so bear with me.....
So i have a samsung galaxy s4 the sgh-s970g, and a customer needed it unlocked so I thought I would give it a try. Its been a fun phone to mess with. So I am on 4.2.2 and this is the only version I have tested on. I havent tested on 4.3 so let me know if it works for you.
So my baseband is MH3. I used saferoot to root the phone and then I used the twrp for the m919 version to get a custom recovery. after this i went into recovery and made a nandroid. I would advice you do the same if your going to try this, because I am in no way responsible for anything that happens to your phone it will trip your knox counter and your warranty is now void.
ok so I have a tmobile sim in the phone the whole time because it gives you a invalid sim message and when you get rid of that the phone is unlocked. Now I flashed the wicked v-8 4.2.2 custom m919 rom onto the phone. And after that i booted it up like normal and had no problems booting it. So when it finally boots up this is what I see....
know with the tmobile rom it is asking for a sim unlock code. This is where it gets a little tricky.. Youll need to download region lock.apk
you can get it from the play store or from the developer on xda, (great app by the way). So now is when i procedded to use spt box to unlock part of this but i believe you can do it without the spt. so just set your phone up and when your done your settings should look like this... youll still have straight talk radio but everything else including kernel is the tmobile m919.
Ok so now go ahead and open up the region unlock apk and instead of pressing unlock your going to lock it. when its done go ahead and reboot it and then its going to ask your for a password again but this time you know it.. Its going to be 00000000, or atleast it was for me but like I said i dont believe spt is needed to reset the efs i believe the region lock apk will do this and it shoould say unlock succesful like this...
the only kicker is anytime you reboot your phone your going to have to run region lock and lock your modem and then reboot and type in the 8 zeros to unlock if someone figures out a better way that would be awesome.. I also believe this method could be used to help unlock the s4 l720t and sm-n900p without the assisstance of sprint. Any feedback and help would be greatly appreciated and enjoy your unlocked phone....

Region away app works only up to 4.3, so I guess you need to downgrade the baseband to L720T's MK3 modem.
No harm in trying.

the l720t was actually shipped with a 4.2.2 rom and if you could find that modem for the 4.2.2 it was originally shipped with you can unlock it

I can only find a 4.3 ROM for L720T not any version before it.

So, just to clarify, do we have to use the ROM or can we do this on stock? I have two of these LTE-T marked phones from Straight Talk that I'd like to use AT&T Straight Talk SIMs with.

tried this on a stock tmobile mdl firmware with the mh3 baseband with no go.. What am i doing wrong?

Yes i have, Tracfone will have to provide an update to fix the issue. Reason is that everytime you enter the code its accepted. But as soon as you reboot the phone it asks for the code again. So not sure how tracfone will handle this.

Well I returned my $250 Black Friday special as I just have no faith in getting an unlock code for these Galaxy S4s as I wanted to use it on AT&T and I had picked up the Tmobile version. I'll have to settled for a used item instead.

So will this phone work with a straight talk att Sim and a tmo Sim as long as its through ST?

After fallowing all the steps I get to the 8 0's hit enter and it just sits at the screen, and says unsuccessful. Sgh-s970g bb:mh3 av:4.2.2

Anyone know of a pay site to unlock this device. The one legit one was for over seas and I'm in US. I tried offering straight talk money and they said this phone needs to be active for 5 more months before they'll provide me the unlock code. I guess you need 12 months of active service to be eligible for the unlock program. The only thing is, is it will only work on a straight talk T-Mobile Sim until then. Tia.

It DOES work. I installed the wikid v8 rom on a SHG-S970G this morning, opened region lock, unlocked modem, relocked modem rebooted, and entered my unlock code and BAM, Successful unlock. Thanks a grand! By the way i bought the unlock code on a 3rd party site. Im now running ATT on the phone.

Straighttalk will only unlock phones purchased on or after Dec 2013, currently active on ST Service & have been active for 12 consecutive months, if you call the unlock department you will be transferred to their automated information center if your phone is not eligible for unlocking, this is just to inform you of the requirements to unlock your device.

ST unlock
I've had mine 6 months... Called them 5 times and they told me everytime they couldn't unlock my phone (sgh s970g). So.. I used CHIMURA to root for free. Installed the m919 twrp for recovery. Installed wikid v8 using twrp installed regionlockaway locked the modem rebooted, entered my unlock code and it gave me a successful unlock. As stated I'm running a Straighttalk AT&T sim on mine.

Extrapolate to S5?

Do you think a similar technique can be applied to a Galaxy S5 from Net10/TracFone? I tried to use a S902L with my (Canadian ) Rogers SIM card and unsurprisingly, it didn't accept it

Has anyone tested going all the way back to JB via odin then using the chainfire method to sim unlock with success after taking the ota to KK?

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.
Just my 2¢®™
Sent from my T889 N2/N3/S5..

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.

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.

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.
