My friend moved back to Pakistan from Canada recently and brought his phone back with him. Since the phone was purchased from Rogers, it was locked to Rogers network in Canada.
He brought it to Pakistan and had it unlocked for 10 USD at a store.
He isn't familiar with rooting and all so he didn't pay attention as to how the unlock was done and is not sure if it was a factory unlock or not.
He showed me his phone recently and I noticed they had rooted it.
He wants to update his phone to 4.3 Jellybean but he can't use OTA because his device status has been changed to 'Modified'.
If I download a 4.3 firmware for the I747M and flash it will the phone get locked again? On SamMobile, there is a firmware that shows Canda (Rogers) on one of the firmwares, if I download it and flash it will the phone get locked again or will it stay unlocked even though its being flashed with a Rogers firmware.
There is also another firmware with the Country/Carrier showing as 'Unknown' as SamMobile. If I flash this firmware, will the device get locked? What does 'Unknown' mean on a firmware?
Thanks
What OS is on the phone right now? If the phone is running 4.3, do not flash any stock firmware unless it is 4.3 or higher.
I don't think it makes a difference as to whether the phone was unlocked via rooting or code, it will remain unlocked after flashing.
I unlocked my Bell s3, as have many others, using a free method and the phone has remained unlocked, even though I reloaded a stock Bell 4.1.1 rom and then a stock Bell 4.1.2 rom.

It's on 4.1.1 right now. So if I flash a Rogers 4.3 firmware?

You can flash it but I would not do it. The 4.3 ROM will install Knox which can make rooting more difficult and harder to unbrick.
You can install a custom recovery and just flash a custom 4.4.2 ROM. This allows you to easily return to a stock ROM in the future.

My friend does want KitKat on his phone, so how do I flash a 4.4.2 ROM?
Can I flash the CWM Recovery meant for the I747? Will it make a difference if my device is the I747M?
Will I747 ROMs work on the I747M?
Thanks for the help BTW
You can flash Philz Touch Recovery via Odin. Once that is flashed correctly, you can download a ROM, save it on the phone's internal or external memory, boot into recovery, wipe Dalvik Cache, cache, and data. Then flash the rom and reboot.

I just started flashing ROMs onto my s3 and prefer an aosp interface.
I don't know of any that look like stock kit Kat but you could use as theme chooser to find something you like.
I recommend that you not update to 4.3.

You can search for themes on the play store. Many of them require a certain launcher. When you find a theme you like, just download the required launcher and install the theme.
Were you able to load a custom rom onto the phone?

I haven't tried yet since the phone is not with me.
To be honest, I've used 3-4 launchers from the Play Store but they still don't give the same experience as the Custom ROM.
Thanks
Every ROM uses some sort of launcher and certain themes only support certain launchers.
Personally, I like Cyanfox because of its dark UI.

Hi, I'm trying to unlock my Galaxy S3 I747M and I see that you were able to do so via a free method, now would that free method be via a survey, or a magazine deal or Netflix? I'm currently in Trinidad and it comes up with something like, Deals are not available in your country. I would like to use this phone while here on a work assignment so if you could please tell me how you were able to do this it would muchly be appreciated. Its on a Canadian carrier and with Rogers. Also on 4.1.2

The free method is not any sort of offer from any company. In order to use the free method, you need to flash a stock Rogers 4.1.1 ROM via Odin 3.07 because a stock 4.1.1 ROM is the only ROM that has the necessary menu options to do it. If you flash a stock ROM, you will loose all of the data and apps on your phone.
The i747m is a Bell phone. I think Rogers is an i747r.

Is it possible to install a stock ROM once 4.3 and a locked bootloader is in place. I've looked all over and I seem to read conflicting stories. So...
I have a Samsung S3 Telus (AT&T) version running the latest 4.3 as of May1st, my bootloader is locked and I have a tripped flash counter.
If someone actually posts a I747MVLUEND2 rooted image can I flash it?
Can I flash an older version I747MVLUEM series?
Oh yeah my phone is NOT rooted.

I think you didn't understand the question. You pointed me to a thread about unlocking.
With a 4.3 bootloader, you will need to install a custom recovery to flash ROMs. If you want to restore a stock 4.3 ROM, try this: http://forum.xda-developers.com/showthread.php?t=2658486
With a 4.3 bootloader, you cannot use Odin to flash a stock ROM unless that ROM was specifically compiled for flashing via Odin.
No this is not possible. I have a LOCKED boot loader. I can't flash a custom recovery as far as I know.
Also how would one know a ROM is made to be flashed by Odin even if it was possible? Maybe I missed something here.
I re-read your original post and I'm a bit confused. You have a Telus s3 (i747m) or AT&T s3 (i747)?
I have never heard of an s3 having a locked bootloader. All of the phones with a stock 4.3 ROM have a bootloader that cannot be downgraded.

Sorry, I have a Telus I747M.
It seems all AT&T and Telus S3's have a locked boot loader after the upgrade to 4.3. This means you cannot flash CWM recovery to the phone anymore.
So, I beleive I can't fix it to put CWM recovery on but I may be able to flash a stock rom, I'm just not sure at this point what I can do. Based on your response it is not surprising I'm confused, there seems to be a LOT of conflicting information.
There are some stock ROMS that have already been rooted and I'm hoping I can flash one of those without bricking my phone.

sir, the one who got the wrong idea is you
the only S3 with locked bootloader is the verizon version

which occurs to me that you might have done something wrong trying to root your device
though i've never tried this tool to root but many people succeeded rooting their phone with this http://forum.xda-developers.com/showthread.php?t=1963790
so try it out
but again, you said to flash a stock rom... you can do it via Kies(is that how it is called? it had been so long since i last used it) or you can just use ODIN to flash it
Regardless of the subject of that thread, the posts I indicated directly speak to your 747m downgrade question.

Can understand why some may be confused about the question. If you have stock 4.3 already (which is the latest version available), why would you want to flash another stock ROM? If you are talking about flashing an older stock ROM, yes it is possible, and there have been several posts on how you can successfully downgrade the system only without altering the bootloader. Attempting to downgrade the bootloader will, of course, cause a brick so downgrading ROM only is a rather complicated process that should be attempted only if there is a very worthwhile reason for this. So far, there are very few arguments, if any, for downgrading from 4.3 to any older stock ROM version. If you are trying to flash a rooted version of the same stock, you need to be sure it's one with the same bootloader. You may, however, find it easier simply keeping the current system and rooting via Safe Root. You can, however, flash a custom ROM if it won't attempt to mess with your bootloader . As far as recovery goes, even if you have stock 4.3, you can still flash custom recovery via Odin or other prescribed installation route. I'm not aware of 4.3 preventing the flashing of a custom recovery. I have an AT&T i747 with stock 4.3 and I've flashed custom recovery several times.

I think that means secure booting has been enabled. Secure booting has nothing to do with having a locked bootloader. From what I have read in other forums, a locked bootload would not allow you to load a custom kernel.
Just purchased an unlock code from Telus but it does not work. I know some posts mentioned it only works with a stock dialer app.
Is there anything else I can try before attempting that?
If not, what stock rom can I even use? And is there a guide available?
Sorry if this has been asked before. I had trouble finding any answers.
Thank you.
Just flash your stock firmware with Odin.
The boot loader on your phone will determine which firmware to load on your phone.
If you have the 4.3 bootloader, don't flash 4.1.1 or 4.1.2.
Flashed stock rom, booted with sim inserted, and entered the unlock code when asked. It worked! Thanks for the reassurance, I was hesitant.
Here are some links I came across that might help others.

Glad to hear you got it to work! Couple things for extra knowledge. ..
You can also get firmware from http://sammobile.com/firmwares. Their downloads are much faster than samsung-updates IME.
Easiest root method ever! - Towelroot (shouldn't trip the warranty bit either)
If I'm not mistaken, the recoveries having problems reading the sd card is due to your hardware version. I believe they found a solution in the Sprint forums, but I haven't had a chance to read up on it yet. If its something I can do I'll probably try to fix the T-Mobile and AT&T recoveries. I may be mistaken on some of that, but its how I understood it after a quick search the other day.

Can you please clarify few things for me?
I have an ATT Galaxy S3 (SGH-i747).

Will flashing to stock ATT ROM brick the phone?
What is the best way to go back to stock ROM?

Thanks for quick reply.
Bootloader on mine is I747UCDMG2 which is from 4.1.2. Hence I should be ok to go to stock 4.1.1 ROM.
I am reading few other posts before making the move.
Flashing the USA version of the s3 (i747) with any i747 firmware from sammobile in Odin can brick your phone us you have a 4.3 bootloader or higher.
Since you are on 4.1.2 bootloader, flash the stock ATT 4.1.1 ROM from sammobile.com using Odin. After flashing, do a full wipe in recovery. Boot the phone and use the free method to permanently sim unlock your phone.
After unlocking your phone, you can run OTA updates to get to the latest stock ROM, bootloader, and modem.
Just confirmed bootloader and baseband are I747UCDMG2.
I will update here how everthing goes.
PS: I DON'T want to go to I747UCUEMJB bootloader after unlock. That will mean, I will not be able to downgrade in future. AFAIK, I747UCUEMJB bootloader is also locked.

correct in that you will not be able to downgrade (serious risk of bricking your device).
bootloader is not locked on the S3 AFAIK. (bricked my s3 on mj2 trying to 'unlock' an already unlocked bootloader.).

I agree that the bootloader is unlocked.
I think at times people are calling the newer bootloaders locked because they are unable to downgrade them. Whereas we are calling them unlocked because we can still root them and flash custom/unsigned ROMs.
ATT has been locking the bootloader on other phones such as the Note 3, HTC One XL, and the Moto G so I'm not surprised that owners think their bootloader is locked.

Thanks all for the assurance and support.
I was able to ODIN to stock ROM and SIM unlock the phone.
Background: My ATT S3 i747 was running CM11 Android 4.4.4. Baseband and Bootloader was I747UCDMG2.
Steps:
1. Flashed rooted stock ROM (root66_ATT_I747UCDLK3.7z) using odin from http://forum.xda-developers.com/showthread.php?t=1739426
Followed the steps in OP.
After flash ODIN showed PASS and phone rebooted. It was stuck in Samsung logo. I booted into recovery. Performed a wipe cache and factory restore.
Phone rebooted successfully after that.
2. Inserted non-ATT SIM and it asked for the unlock code. I had obtained the code from ATT before. Used the code and phone was unlocked.
The same code did not work while I was running CM11.
NOTE: When running stock ROM you can follow steps in below threads if direct unlock did not work for you.

Hey guys,
I got a I747 I want to give to my mother as a gift.
I downgraded 4.1.2 to 4.1.1 and ran the secret menu unlock to unlock the sim card, that worked perfectly.
Now I want to update this out of 4.1.1 to 4.4.2 but I cannot find a stock firmware to run on odin anywhere.
Do I need to go to 4.3 first? Is there a stock firmware for that?
SamMobile stops at 4.1.2... OTA obviously doesn't work.
How Can I get this done..

I have a Motorola Atrix from Bell. I flashed it with stock ATT firmware and received OTA updates from ATT over wi-fi.
Since you have the i747, start with stock pre-rooted ATT 4.1.1. This will flash the stock recovery, radio, and bootloader. Run triangle away, flash a stock unrooted ATT stock 4.1.1 ROM, and take the OTA updates.

Can I flash a bell i747m 4.4.2 image onto this i747 or will it brick?

You can flash i747m firmware on your phone but DO NOT flash the radios or bootloader from an i747m to an i747 and vice versa. Bricking is a really possibility if you do that.
Do you have a custom recovery? If you do, you will need to install a stock recovery.
Try resetting the phone (wiping cache, data) in recovery or through the ROM itself.

Alright, I have the stock recovery. How do I not flash the radio and boatloads when using the firmware from sammobile?
You cant. You cannot flash another devices firmware. Odin wont let it happen and if it did youd end up hard bricked due to mixed firmware. For example your sbl1, modemst and param partitions (plus others) would be i747 and youd be flashing sbl2, sbl3, rpm, etc from an I747M.
The only thing you could use are the system partition and kernel, nothing else. There are two ways to accomplish this, one is to build a rom from the firmware and flash that. The other is to flash with mobile odin, but that requires root and youd still have to be very careful.
Another priblem I see you encountering is you cannot run 4.4.2 without 4.3 or newer firmware. It will not boot otherwise.
You need to go to the General section and follow one of enewman17's tutorials to get to either 4.3 or 4.4.2. Personally, I dont see any other way you will be able to accomplish it.

Alright, based on Doc holiday, and others they say It cannot be done and from my experience I beleive them.
Thank you,
It's very difficult to do this when others are giving bad advice.
So for the record, cannot flash i747m firmware to i747.
Thanks!
The annoying part here is I can do it with my m7, I just flashed the Dev edition onto my Bell m7 with no problems.
All devices are different in many ways. What is perfectly safe to do with one brand or model can brick another.
And I wouldnt call it "bad" advice... I've seen audit13 and others helping lots of folks with very good advice. We all make mistakes and we all have more we can learn about these devices. No one knows everything about this stuff and shouldnt let that prevent them from trying to help.
Those who are trying to help are doing so with the best of intentions and tell people what they think could be the best way to solve a given problem. In cases like this one, its easy to see how anyone would think its ok to flash different firmware between similar models based on being able to do so on other devices they are familiar with. (If I had gone into those forums I wouldve been telling people the opposite and ended up being wrong there.)
All I can say is chalk it up as a new lesson on a different device, and I hope you still appreciate that someone was trying to help.
@audit13 I hope none of this discourages you from helping. Ive seen plenty of threads where your advice was sound and appreciated, and I am glad you have been around to help so many people out!
Now, back on the problem at hand... if you want to be running the latest 4.4.2 kk, you will have the option to use the OS (/system and kernel) from either the I747 or I747M firmware. But first you must fully update to a minimum of the 4.3 MJB firmware for the I747. Once you have this running for your base firmware/bootloader, you can then run the Bell or AT&T (4.3 or 4.4.2) system. (I hope this is making sense!)
So first, update the full 4.3, MJB, firmware via Odin. (Theres a thread in General with the file, ill post the link in a min).
If you want to update to 4.4.2 firmware, you can then follow enewman17's tutorial to do so via OTA.
You can then either stay with that, or use Mobile Odin to flash ONLY the system and kernel from the Bell firmware.
Let me know if any of that needs better clarification! Also let us know what your ultimate goal is. From the options you have, where do you want to end up?

After updating with the 4.3 firmware, you can first try using the official ota to update. Then, if that fails you can go to enewman17's thread and try his method.

Hi all, I have an SGH-i747 with ver 4.0.4 which has been rooted. I will like to update my version systematically with the original updates i believe there where from 4.0.4 to 4.1.1 then 4.1.2. then 4.3, 4.4.2 etcc.. its there a place where i can find the original ups, my phone will not take the original firmware updates on its own. Reason is once i try to flash any ROM pass 4.1.1 i loose the Mobile Data getting the no sim inserted msg and no signal, forcing me to go back the original state in order to work. seems there is a problem with the modem once i go pass 4.1.1. .. thank you.
What bootloader version is on the phone? Where did you get the firmware to flash? You're using desktop Odin to flash?
Are ota updates an option for you? If they are you can unroot and flash the stock recovery; it might be easiest just to Odin back to stock.
Otherwise enewman has posted firmware updates to xda. They are bootloader + modem zips you can flash in custom recovery. You have to flash them incrementally, mjb then ne4 then nj1. Search the forum here and you'll find them. Just be careful and read read read those threads. Messing with bootloaders is the best way to hard brick this phone.
I'm in a similar situation - I've been on a custom version of the Stock ROM for 4.1.2 - never bothered to update the bootloader because I had the soft unlock done, didn't want to lose it. Now I'm bored with it. I'd love to get up to 4.4, or even a 5.0 ROM... but not sure the steps needed to do so. I'm vaguely aware that I have to update the bootloader/kernel, etc... but it seems like I'm 4 years behind the curve with all the ROMs and threads about bootloaders, and I've lost my touch.
That thread with the list of bootloaders sounds good though, I'll go looking for it to start I guess.

Here you go. This TLDR post has all enewman's firmware update threads linked to it.

Thanks! I'll give it a look, down a couple of shots of liquid courage, and give it a go this weekend.
EDIT: Yikes, didn't take long for that to fizzle out. I'm using a i747M. Noticed that my current baseband version isn't listed anywhere on that thread. Hmmm. Oh well, guess I'll do some more digging later...
With an i747m, you can flash the latest 4.4.2 using firmware from sammobile.com and desktop Odin.
Do I need to do them in sequence, or can I jump to the latest? I'm assuming once I've flashed the stock firmware, I can load any current custom ROM?
@gfinockio, is your phone sim unlocked? If not and you don't see any mention of the warranty bit in download mode, you could flash back to stock 4.1.1, use the free method to sim unlock, and then run OTA updates until you are running the latest ROM. OTA updates are the safest route to upgrade the phone.
If you phone is sim unlocked already, you could flash directly to the latest ROM; however, you will not be able to downgrade the bootloader as any attempts to downgrade the bootloader could hard brick you phone.

I used the "free unlock" in 4.1.2 (so it's unlocked) but I thought when you upgraded the bootloader you lost that lock. Now that I believe that isn't the case (and I've used a different tool to unlock as well), I may just try the OTA updates. I was with MTS (Manitoba), but now I'm with Rogers, so I guess I would just use the Rogers OTA images to upgrade from 4.1.2 to 4.4? Do I use Odin or whatever to do that? Once I upgrade to a "stock" image, won't the updater just prompt me to upgrade again and again until I'm "up to date"?
Unlocking the phone via code or the free method is permanent even after upgrading the ROM, bootloader, and modem.
The carrier ROMs for the i747m are pretty much identical but I always recommend sticking with the original carrier's ROM. If you download the stock image from sammobile.com, use Odin to flash the ROM.
OTA updates will not work with a rooted stock ROM too.
When i search for the stock firmware on sammobile for the i747m, it doesn't have any listings. Are you able to find it on there? I don't see it.
Search for the sgh-i747m.
