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..

You can just flash stock 4.1.2 firmware from sammobile and then run OTA updates.
I also found this on sammobile: Canada (Bell Mobile) (Black Edition), Version: Android 4.4.2, PDA: I747MVLUFNE6
CSC: I747MOYCFNE6, MODEM: I747MVLUFNE6

Will it work though.
I have it already on my pc, I updated my wife's with it.
If I update to 4.1.2 will OTA come? Even with the I747(not the I747m) on the Bell network?

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.

Ok, so I guess it wasn't clear, my bad.
I have 4.1.1 stock firmware on my att 1747. It has never been rooted.
I run the Ota and I got an error, now it tells me "Your software is up to date".
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.

WARNING!!!!
Do not flash a 4.4.2 modem if you are running 4.3 firmware (bootloaders)!!!!
This will cause a permanent hard-brick!!! There is no fix!!!
The only reason anyone should need to flash one of these is if they had flashed a 4.3 or earlier modem for whatever reason. Once updated to 4.4.2 firmware, ONLY that matching modem will work. Flashing anything else will result in no signal and most likely an "Unknown" baseband and IMEI. If you flashed an older modem, you will need to flash back to the 4.4.2 one and these will all come back.
This has happened a number of times already, and continues to happen still. So I figured I would put them in a separate thread to make them easier to find.
Flash from the recovery of your choice, or Mobile Odin. The updater-script for these includes an assert that should prevent flashing on anything that does not have the correct bootloader.
Full Disclosure: I do not have an I747 or I747M, and as such, I am unable to test any of these. I have full confidence they will work as expected though. (I have been doing the modems for the T999 for a couple of years now). Still, you should know they are currently untested.

These modems will only work if you have updated to the latest 4.4.2 base firmware and bootloaders. The ROM you are running is irrelevant. If everything is currently working, you have no need for these.

You probably never updated your firmware to 4.4.2.
To know for sure open terminal emulator and enter this.
getprop ro.bootloader
If it says MJB, you haven't updated your firmware yet and flashing this modem would permanently break your phone. If it is MJB, flash the same firmware via Odin and factory reset. That often fixes the imei problem. If it does not, pm me for further help with it. Can't post those instructions here.

Thanks for keeping the support for this phone going. I have the latest bootloader ..uemk5 for my Rogers sghI747m.
I tried to flash this and got a status 7.
I have been using the ..UEND3 Modem up till now.
You need to update first or this modem would permanently brick your device. MK5 is a 4.3 build. I think the latest Rogers is NF2. You cannot flash this modem unless you've already updated. And then you won't need this. I released these because some mistakenly flash the older 4.3 modems after updating and find it won't work, so they needed a way back.

No Cell data after root and new rom and recovery.
Hi,
This is a repost from the S3 help forum as the OP here seems very knowledgeable about modems and bootloaders. Excuse the redundancy.
I was given a used ATT I747 s3 which had stock 4.3 , modem/bootloader mjb, and knox. I rooted, removed knox and installed slim 4.4.4 rom, lean 4.4.4 kernel and latest philz recovery. All running ok
including cell calls to/from phone, mms, apps and wifi data. Same modem/bootloader (MJB), IMEI accurate after upgrade. However ATT cellular data will not connect and or transmit and/or receive using att, phone or lte APN.
Any help/thoughts appreciated?
Could be the rom. I've been hearing about a lot of connection issues on cm/aosp based roms lately. Try flashing back to stock to see if it works.
Sent from my SAMSUNG-SGH-I747 using Tapatalk
Nevermind I re read. Did it work before you installed lean kernel?
Sent from my SGH-I747M using XDA Free mobile app
In my upgrade process, the first thing I did, after the recovery had been updated to Philz, was install slim rom and lean kernel together and at the same time. That was when the problems began. They went away when I reinstalled slim rom only (without lean kernel). Everything now ok. Hope that helps.
I'll start by saying I'm very much a noob but read and read as much as I can and have been following quite closely a lot of the s3 development so anyone feel free to correct me if I'm wrong.
It seems in the past few months a lot has changed with kernels and compatibility has broken numerous times. If the dates of the releases of kernel and Rom aren't quite close then some commits in the rom could break data, wifi, etc. If your running the latest nightly Rom make sure your using a recent kernel. Always just make a backup before flashing custom kernel and then you can revert right back if the kernel breaks anything.
Hope that helps...

I'm currently on MJB and I'm looking to update my bootloader/modem combo to the NE4, but before doing so I'd like to have on hand a stock NE4 Rom to fall back on if needed (since I can't use the stock MJB one that I have at that point).
I've been looking around but can't seem to find a Stock NE4 file. Can anyone point me in the right direction? Thank you.

There is no stock AT&T ROM beyond LK3. Once you are on mjb, you can only flash stock ROMs that have been specifically compiled for flashing via Odin or TWRP/CWM.
If you want to revert back to stock from a custom ROM, look for stock flashable ROM on the general section of the i747 forum.
i747 from at&t rooted and twrp installed . Flashed CM12 5.1.1 no signals from t-mobile.To make it work on T-Mobile from att stock i had to flash QCN(t999) via QPST by code *#7284# to change into diag. . But now after flashing cm12 ,it is not giving me signals .No calls no DATA . Now i can not flash T999 QCN again because secret codes are hidden . Is there something i can do, to get signals on CM12 . I want to enjoy 5.1.1 !:silly:. . I already tried all of the (i747)lollipop roms same results. can i flash tmobile rom on att is it possible (radios are different ) will that work ?. I forgot there was an apk that could bring up secret codes window forgot the name. If anyone knows or have a link .
You can flash the T999 roms, just not the firmware.

You never stated what bootloader and modem was on your device before you flashed any of the Lollipop Roms. On the i747 you need at least the NE4 bootloader and modem to get signal on 5.x.x.

Correct with the NE4 bootloader you can not downgrade without bricking your phone. Downgrades went out the window with MJB (Jellybean 4.3) and have not returned. Meaning you can never downgrade on MJB, NE4, NJ1, or NJ2.
With LK3 you could go upto MG2 (JB 4.1.2) or MJ2 (the leaked release of 4.3) and still be able to downgrade. I have downgraded while on MJ2 with no issues. I went down to LK3 from MJ2 in order to utilize the free sim unlock, I think DocHoliday mentioned it earlier. Since then I have gone back up to MJB and then to NE4, so I can no longer downgrade.

Hey dawgdoc ,
I just turned another device into paper weight man .It had LK3 and i tried to flash MJB via odin stock firm from company but end of odin it f**king hard bricked the phone is there something i messed up . The bootloader were from DLK3 (rooted and twrp) but if i was just flashing new firm from odin it was not supposed to brick it just wondering what am i missing throwing my 500 for 2 phones into garbage !
Do you get any response from the device at all?
Plug into the computer and open device manager. Does it show connected as QHSUSB_DLOAD, or something else?
Did odin complete the flash and say PASS when it was done?

Where did you get an Odin flashable 4.3 stock rom? As far as I know AT&T never released an official one, nor have I ever seen one on sammobile. There may have been one put together by either loserskater or enewman17, but that one is rather hard to find.
Going from LK3 to MJB should cause no problems, I have done so myself. Going from NE4 to MJB is risking bricking your phone. I have read of some who have recovered from the bricking caused by the NE4 to MJB downgrade. Those used a debrick image on an external sdcard, the image was based on the bootloader that was running before the phone/device was bricked. There may be in the forums, but I'm not sure of that.

To run a Lollipop ROM you will need to be on at least the NE4 bootloader and modem. You can find them in his NJ1 or NJ2 threads. It is not necessary to flash the ROMs, just the bootloader and modem. If you don't flash some KitKat or LP rom after updating the bootloader and modem, you may have issues running the MJB ROM. If you want newer than the NE4 bootloader and modem, be sure you flash them each in order, don't skip NE4 or NJ1 if you are going all of the way to NJ2. All of the mentioned bootloader/modem files can be found on enewman17's AFH profile.

I haven't tried any LP roms, so the best I could do is parrot back what I read in the threads. Correct on the flashing instructions, I have read of many doing so to go to LP. Others flashed the ROM first and then booted. They had issues with wifi, bluetooth, data, calls, etc until they went back and flashed the bootloader and modem.
What's the highest/latest firmware can I go for a Galaxy S3, model SGH-I747...?
I believe 4.4.2 nj2 is the newest.
where can i get the latest rootable odin firmware?
All of the stock firmware is rootable with twrp and supersu.
And where can we get last 4.4.2 for our phone?
I currently have 4.3 on my SGH-I747.

If your device is stock the simplest solution would be to take the OTAs until you are at the most recent stock rom (NJ2).
If you are not stock you could revert to stock and take the OTAs. You also have other options. Since you have the i747 you should update sequentially, not skipping any of the releases, if you are on the 4.3 or newer bootloader and modem. (I have read this is not necessary for the i747M.) If you have a custom recovery installed you could use it to load the bootloader and modem files, in order, and then flash a compatible custom ROM. The downloads for the bootloader and modem files are available in threads by enewman17.
I haven't been specific, but then for anyone helping to be specific detailed information is needed.

I'm running CM 12.1 on my phone, and I believe there is even a CM 6.0 ROM out there... I also have the I747
right now from what I can see depending on what model you have the highest I can see is
4.4.2
Model SGH-I747M
Model name GALAXY S III
PDA I747MVLUFOB3
CSC I747MOYCFOB3
If the OP has the i747, nj2 is the newest stock ROM.
