I've got a Galaxy S3 I747 it is currently running 4.1.1, I747UCDLK3 Baseband. I'm not exactly a noob when it comes to flashing and rooting, I know my way around CWM and Odin pretty well. But I have a few questions on this 4.3 OTA. (I am a forum noob)
-Will I still be able to root? (I heard CF works for it)
-Can I install CWM? (Is the Bootloader locked??)
-Will I be be able to I flash other roms than the 4.3 TW like CM11Snapshot? (Is the bootloader locked?)
-What the h*ll is knox and why should I be worried?
-What is with the boot loader downgrading thing? (Have to do with locked bootloader??)
I AM NOT AT ALL WORRIED ABOUT A FLASH COUNTER OR VOIDING A WARRANTY I AM NOT ON A CONTRACT . I JUST DO NO WANT TO HARD BRICK MY PHONE.
If you take the OTA 4.3 update, it will install Knox and the 4.3 bootloader.
The 4.3 bootloader cannot be downgraded and attempts to do so will probably brick the phone.
You can root the stock 4.3 ROM with auto root but Knox may interfere with the process of cause issues after the fact.
You can still install CWM. I rrefer Philz Touch which is CWM-based.over TWRP.
So can I still flash roms?

Yes, you can flash ROMs. Is your phone unlocked? Since you're on 4.1.1 stock, you can unlock it for free.
Personally, I avoided the 4.3 update because it installs knox and the 4.3 bootloader which can cause problems when using Odin to get back to stock.
I have a Canadian version of the s3 and I'm able to run KK ROMs with a stock 4.1.2 bootloader.

Unlocked as in Bootloader? Yeah I've been able to flash roms via CWM and Odin on 4.1.1 and as in Carrier unlocked? Yes I use Straight Talk on this ATT S3
If I got the 4.3OTA I wouldn't need Odin to go back stock if I flashed a ROM would I? I could just make a back up via CWM then restore later if I wanted right rather than using ODIN?
See I can't use KK roms because I have the 4.1.1 BL so is there a way I can upgrade my boot loader to the 4.1.2 version??
Would I lose my carrier unlock if I upgraded to 4.3 or if I upgrade my bootloader??
I suggest downloading a ROM you want to try, then unzip the ROM and look at the updater script to see which bootloaders are supported. The updater-script file is located in \META-INF\com\google\android\updater-script. You can use a text editor to open the updater-script file.
The first few lines will list the bootloaders that are supported. I run Validus which is a KK ROM using a stock 4.1.2 i747m bootloader.
Do you know about this > "If I got the 4.3OTA I wouldn't need Odin to go back stock if I flashed a ROM would I? I could just make a back up via CWM then restore later if I wanted right rather than using ODIN?"
Also couldn't I just upgrade my Bootloader and Modem from here?

I feel like if I upgrade my boot loader then I won't have to worry about restrictions.
Would I lose my carrier unlock if I upgraded to 4.3 or if I upgrade just my bootloader??
I ended up flashing the MG2 Modem and Bootloader, I'm good now, also if I want 4.3 I saw loserskater has a leak version that will be good and wont not let me downgrade my bootloader.
Hi everyone,
I am looking for a way to sim unlock my S3 so my girlfriend can use it on Telus (I just got an OPO )
Before I purchase a code, I have a few questions, if anyone knows the answer
1- Will an unlock code work with my setup? (I am seeing reports of it only working on Stock 4.1 and whatnot)
2- Where is a good place to purchase a code? (Rogers a crooks with a 50$ fee and I don't wanna get ripped off online either)
Thanks!

You will need to be running a stock or close to stock ROM in order to use the unlock code. You do not need to be on stock 4.1.1 to use an unlock code. You need to be running stock 4.1.1 if you want to unlock using the free method. You may be able to unlock it using a code if you are running a stock dialler.
What bootloader or baseband is on your phone?

I managed to get a code from Rogers for half the price, which is "not that bad" I guess...
I have yet to try it as I don't have the SIM card with me atm.
Baseband: I747MVLUEMK5
it's my understanding that downgrading from this will brick your phone...
Thanks for all the info!
Yes, trying to downgrade from mk5 will brick your phone.
Find the stock Rogers ROM from sammobile.com and flash it via Odin. Flashing back to stock will wipe all user data and files so make sure you backup everything you need before flashing back to stock.

Ok I tried the code and it didn't work.
I'll read up on the Odin procedure... I've done it before on another phone but I wanna make sure I don't end up with a brick! Thanks!
Sent from my A0001 using XDA Free mobile app
ah one more thing... since I'm using the unlock code (I don't believe the free method works on Rogers phone anyway) should I flash to stock MK5?
If I go to stock MK5, eill I be able to come back to CM afterwise?
Thanks!
The free method will only work if you are running an i747 or i747m on stock 4.1.1 including the bootloader.
If you flash back to stock mk5, you should be able to re-install cwm and CM11. There are many threads on disabling knox and install CWM.

Hi! Reporting back, everything worked well flashing stock rom using this method:
http://forum.xda-developers.com/showthread.php?t=1739426
I had a slight problem after the Odin flash where I had to boot to recovery and factory reset to get out of a boot loop, but everything went fine after that.
I managed to unlocked the phone, changed the recovery using the aforementioned thread and got back up and running on CM11 M10 in no time!
Thanks a lot for your help sir =)

Hey guys I am trying to update my galaxy s3 to kitkat. I am running galaxy s3 at&t variant 747 rooted 4.1.1. I747UCDLK3 update to kitkat. I realized I need to update to 4.1.2 first before doing the 4.3 update. I can't seems to find files I need for 4.1.2. Can someone point me in the right direction. Thank you for your help.
Are your running stock 4.1.1? If you are and your phone is not sim unlocked, unlock it using the free method. Once unlocked, use Odin to flash back to stock unrooted 4.1.1 and then run OTA until you get to KK. It's a longer process than trying to flash straight to 4.4 but is a safer method for people that are new to flashing ROMs.
I am on the stock rom 4.1.1. Does CWM recovery need to go back to stock as well? That is a good idea to unlock before I update.
If you flash back to stock 4.1.1 with Odin, it will wipe everything and put the phone back to completely unroot stock and stock recovery. Stock recovery and being unrooted is required for OTA updates.
Ok is this the link to unlock phone?
http://forum.xda-developers.com/showthread.php?t=2529200
Yes, that's it.
I can't seem to find 4.1.1 rom file links seem to be bad on unlock page.
There are stock rooted 4.1.1 images here: http://forum.xda-developers.com/showthread.php?t=1739426
You can use the free unlock method even if the ROM is rooted.
For some reason the at&t mirrors don't seem to be working either.
Mirror2 for the stock rooted 4.1.1 works for me.
I would like to root again after kit kat Is it easy to root with knox? Does unlock stick through kit kat? I really appreciate all of the help. Great website. Great people.
Many people have had success with rooting by using Towelroot.
The sim unlock is permanent.
Let me know how it goes for you @thepar. I expect to be updating to kitkat in the coming week.
For the benefit of those searching the forums to unlock their phones my experience may be of help to those on 4.1.2 or possibly even MJ2. I have had my SGS3 since June 2013 and only allowed one update, that was to 4.1.2. My phone was rooted long ago, but I just unlocked it earlier today and that was with a custom recovery in place and without unrooting. In my case I did not revert to the 4.1.1 rom. I did downgrade the modem to dlk3, that of 4.1.1 while leaving the rom and bootloader at MG2. After completing the unlock I upgraded the modem back to MG2. I have confirmed that SMS, MMS, phone, and wifi functionality is intact.
In truth, I will probably not go back to stock to get to kitkat. I am considering upgrading to the leaked MJ2/4.3 bootloader and MJB modem and then flash a kitkat rom which will work on them, there are several.
I just did the unlock yesterday. I need to find someone with a t-mobile sim to test if the unlock worked. Will I still be able to update the OS even though it is on rooted stock? What will it update me too?
I am kind of debating if I should install a custom rom minus KNOX.

If you want to run an OTA update, you need stock recovery and an unrooted system.
I have a stock recovery but the os is rooted. I don't mind using oden to update the os. I might be better to install a rom with knox removed. I can't seem to find 4.1.1 stock unrooted. I did find 4.0.1 ICS.
You can find a stock ATT 4.1.1 ROM on sammobile.com.
You cannot use Odin to flash a stock KK ROM because it was never released in an Odin format by ATT. ATT provided the KK update via OTA updates. Complete KK updates were provided for i747m only.
Thanks so much!! downloading now.
Let us know what happens. Cheers
I have decided to go custom rom route. It is better to update stock ota first then install custom rom or custom rom straight from 4.1.1?
I was on CM 10.2.1
I upgraded to CM11 - I get no wireless data. My phone works but I have no APNs and I could not add them.
I tried SlimKat 9.0 same issue with the APN
I upgraded my CWM to 6.4.0.7 as I heard that caused issues when upgrading to CM11.
I bought Mobile Odin and flashed that way as I thought it might help.
Ive done the following to fix my APN
1) Loaded an old one from working CM 10.2.1
2) Run Root Tweak with the fix APN for CM11 checked
3) Done the airplane mode trick
4) Attempt to add one manually
Does anyone know why this is happening and more importantly how to correct this issue?
Yes I did pore through other threads on how to fix this but no avail.
Thank you

Data does not work on ROMs beyond cm10.2 because your bootloader and modem to too old.
I recommend flashing back to stock 4.1.1, sim unlock your phone if it is not already sim unlocked, and run OTA updates to at least 4.3, then install recovery and CM11.

Thanks for the quick reply. That sounds hard. From what I'm reading going back is treacherous.
So these are the steps.
1. Load this firmware via ODIN -> I747UCDLK3_I747ATTDLK3_I747UCDLK3_HOME.zip -- What about gapps? Is that in this zip?
2. Run triangle away. (Do I need to do this?)
3. Contact my carrier to unlock my sim. (If this is carrier unlocking ie taking my att phone to Sprint etc, why is this needed?)
4. Get OTA updates. Will this come automagically because I'm on 4.1.1 and does it matter if my flash counter is gt 1?
5. Root phone via Odin with this file CF-Auto-Root-d2att-d2uc-samsungsghi747.tar.md5.
6. Install CWM if it went away when I went back to firmware - Of course it would because I'll factory reset my phone in step 1.
7. Flash away to a 4.4.4 Rom
Did I miss anything?
Step 4 is the one that scares me -- That one is out of my control. Either I get the OTA or I dont. Anyway I can "request" the OTA?
Thanks again
Be Well
From your custom ROM, run triangle away to reset counter and change things back to official.
Now flash back to stock 4.1.1 using Odin. If your phone does not boot, you need to get into recovery, do a factory reset, and reboot the phone and go through the set up routine.
After loading stock 4.1.1, do this to sim unlock your phone for free: http://forum.xda-developers.com/showthread.php?t=2529200. If you have a code from ATT, you must be running a stock ROM or a custom ROM that is based on a stock Samsung ROM in order to enter the unlock code.
You must be on a stock ROM in order to take OTA updates. OTA updates are the safest way to obtain an updated bootloader and modem.
After updating to 4.3, you cannot downgrade the bootloader as doing so may brick the phone.
The choice is yours in terms of what you want to do. As you found out, some ROMs will not function properly without an updated bootloader and modem. Mixing modem and bootloader versions may also result in a bricked phone.

To stick with 10.2 or not to that is the question. Everytime I flash or do anything like this on my phone - I get a small lump in my throat knowing I'm dancing in the razors edge of bricking it.
I know how you feel, but I've done it enough times and just accept the fact that I may brick the phone. Jtag service would cost me around $75 so I'm willing to take the chance. I'd be less willing if the phone still has warranty.
Flashing back to stock and running OTA updates is the safest route.
If you don't sim unlock while on stock 4.1.1 and you want to sim unlock your phone in the future, you will need to be on a stock or virtually stock ROM in order to enter the unlock code.
Used ODIN to go back to stock 4.1.1.
Got the OTA update to 4.3
I have my MMS and cellular data back
I'll stick on stock, unrooted 4.3 for a minute.
I should be available to root and update to CM11 or SlimKat or any 4.4 rom whenever I so desire and still keep cellular data.
My baseband is I747UCUEMJB. How can I find out my bootloader and modem versions on UNROOTED device?
Your help is much appreciated and your instructions were flawless.

In a terminal or adb shell you can enter this to check your bootloader:
Code:
getprop ro.bootloader
In a terminal or adb shell you can enter this to check your modem (should match the baseband your phone reports in About):
Code:
getprop gsm.version.baseband
I don't believe either of these commands require root unless stock has getprop locked down tighter that AOSP ROMs; I just entered them in a user shell.
There are a couple of firmware updates for your device beyond MJB, NE4 and NJ1. Some users, myself included, had GPS problems that were a bit of a pain to fix on newer 4.4 AOSP based ROMs with the MJB firmware, but data was ok with MJB. Also, you'll need newer firmware if you decide to test drive the lollipop alphas that are floating around. There are custom recovery flashable firmware updates on XDA from a trusted developer if you decide you need that, or you might want to take a couple more OTAs if you're more comfortable going that route. You're already on MJB so there's no going back
The terminal worked
Bootloader and baseband = I747UCUEMJB
What???? I might need more updates for all the roms out there.....ugggh.
"There are custom recovery flashable firmware updates on XDA from a trusted developer if you decide you need that, or you might want to take a couple more OTAs if you're more comfortable going that route."
If I decide to use these flashable firmware updates on XDA from a trusted developer or OTA its same as this: going forward and NEVER going backward when getting firmware updates?, yes?
yes. downgrading bootloader will almost certainly cause a brick.

You guys are on point.
Last night I received another OTA to 4.4.2.
Baseband now at NE4.
Thanks again for taking the time to answer all this -- Really really appreciate it.
EDIT: Can I still use this to root my phone via ODIN or is there a different process for this baseband?
CF-Auto-Root-d2att-d2uc-samsungsghi747.tar.md5
I load this into ODIN, plug my phone in download mode and root away. Does either the file I use change or do I have to use something other than ODIN?
Thanks again
To get root, I would flash a custom recovery and flash supersu from recovery, then let supersu disable know.
The file you named looks to be outdated as it refers to the s3 as d2att. Since unified builds were released, the s3 is now referred to as the d2lte.
I have ROM Manager installed. It has an option to "Flash Clockworkmod Recovery". I just tried it and it failed and I think thats because I dont have root. In the past I've had to root my phone via ODIN, then flash custom recovery then MOD away.
In the past I rooted the S3 via ODIN. With this new 4.4.2 version do I still root via ODIN provide I find the correct file because -> CF-Auto-Root-d2att-d2uc-samsungsghi747.tar.md5 this one is probably for a 4.1.1 version phone?
I would not flash anything for the d2att at this point.
Try this:
Download the latest tar.md5 file from here: https://goo.im/devs/philz_touch/CWM_...Edition/d2lte/
Download supersu zip from here and place it onto an external SD card or copy it to the phone's internal storage: http://download.chainfire.eu/695/SuperSU/
In Odin, uncheck everything except f.reset time. Flash Philz. When you see reset in the status window, remove USB cable, pull battery, replace battery, boot into recovery, flash supersu, reboot.
I am fairly certain that AOSP, or at least CM, de-unified in the past few months. Not that it matters much, other than for the confusion it causes.
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.

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.
