Can I safely downgrade from 4.4.2 to Stock 4.1.1 if I am still on the MG2 bootloader? I know that 4.3 OTA makes this impossible, but I don't THINK I did the OTA. I believe MG2 is the bootloader from the 4.1.2 days. Can anyone confirm?

Get terminal emulator and type in:
Code:
su
getprop ro.bootloader
That will tell you which bootloaders you have.
Anything over 4.1.2 isn't safe to downgrade from.
It says:
Code:
I747UCDMG2
How does that translate to versions? Is that 4.1.2? Over? Under?

Search is fun It's 4.1.2.
You can downgrade to 4.1.1 from it. I'm assuming you're doing that to unlock? If so, you can upgrade your bootloaders afterward w/o losing the unlock (just a fyi).
Do you want to downgrade in order to sim unlock your phone? That's what I did with my Bell s3. Saved me $30.
Just a quick FYI, you shouldn't need to fully downgrade your firmware. Just flashing the 4.1.1 modem should suffice.
And since I know someone will ask, doing this will not work if you've updated to 4.3 or beyond.
In my own defense, I used the Google but was unable to find anything that definitively said one equals the other. It's nice to get the confirmation.
I am downloading 4.1.1 stock now. After some Odin fun, (and crossing of fingers), we'll see if it works. Thanks for the help.

Downgraded to 4.1.1 stock through Odin and...IT WORKED! One small hitch that was easy to overcome. When the Odin flash was done, the phone rebooted to a soft brick at the Samsung logo. Booted into Recovery, did a factory reset and cleared cache. That fixed it. So I have a pure 4.1.1 Stock system now.
Next question: once I'm done with the unlock process, I assume I root it, flash back to my old modem (MG2) and restore my old system? Also, is there any advantage of upgrading my modem to something newer? Or should I just stick with what has been working for the last 6 months?

If you upgrade your modem/baseband, you gotta upgrade your bootloaders as well. Now that you're unlocked, there's no real reason not to upgrade but it what you got works fine, you can stick with it as well.
Factory reset is indeed needed when using Odin (as you noticed). Also, you can restore your backup once you're back on the same baseband/bootloaders the backup was made on.
SO since I updated my bootloader a while ago I forgot which I was on, but now have a need to use this phone with a different SIM card at times. I am using C-Rom 4.4.2. I ran getprop ro.bootloader and I have I747UCUEMJ2.
Would the following process get me back to where I am right now, just unlocked?
1) Make a nandroid backup
2) Odin stock 4.1.1 UCDLK3 (download from http://forum.xda-developers.com/showthread.php?t=2387423)
3) Unlock using free method
4) Root the rom (assuming can towelroot be used)
5) Install new TWRP recovery with Goo Manager
6) Flash MJ2 bootloader (MJ2bootloader/MJBmodem from Enewman here http://www.androidfilehost.com/?fid=23269279319197286 assuming I would need to do this)
7) Restore nandroid

After unlocking, you can use Odon to install a pre-rooted 4.1.2 ROM from XDA and TWRP or Philz Touch from Odin (depending on which one you used to create your nandroid backup). Root isn't required if you use Odin to flash a custom recovery.

I already did that, please read my post again and the original post from first page.
This forum is for the i747 which is the AT&T version of the s3. I think the t999 is the tmobile version. The info in this thread would relate to the att version.
The bootloader labeling for the att s3 and tmobile s3 are different.

bootloader is mg2 which corresponds to android version 4.1.2. i think on the samsung website or maybe android website i saw a chart with which versions corresponds with which bootloaders. (although that might only roughly apply , as i was on NE4 but not running KK ).
search is fun. google is your friend. :thumbup:

You're in the wrong subforum but MF2 is 4.1.2 (yay for google). Which means, you should be safe to downgrade to 4.1.1 from it. That being said, I duno much about the T999V.
Also if you read back to my first reply to this thread, I gave the solution.

Thanks a lot for your time guys.
Been digging through old posts, im in same situation as OP was, but does anyone have a link for Stock 4.1.1? Root is non-issue. would rather not pay for sammobile.
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

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.

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.

If you are sure you have the i747m and not the i747, you can flash the 4.4.2 ROM from sammobile.com using Odin.
yup its a i747m..but still anyway to confirm it ?
What baseband and bootloader is on your phone?
android 4.1.1 i747m baseband-i747mvldlk4..so whats the safest method now to go to 4.4 ?
Flash back to stock LK4 using firmware from sammobile.com and run OTA updates to 4.4.2.
any other alternatives ? my phones already rooted/custom recovery installed..also i would prefer a custom 4.4.2 touchwiz rom ?
cant i straight away download the stock firmware from sammobile 4.4.2 for i747m & update manually via odin ?

You can. I suggested starting with 4.1.1 because it's easier to revive the phone if something goes wrong when flashing 4.1.1 in Odin. If something goes wrong when flashing 4.4.2, it could be harder to unbrick.
I'm using SlimKat 4.4.4, yet my phone's baseband version is 4.1.1 (I747UCDLK3). I'm looking to upgrade my baseband version to 4.4.2 due to some issues.
Can I upgrade straight from 4.1.1 to 4.4.2?
Or do I need to upgrade to 4.1.2 -> 4.3 -> 4.4.2? If this is the case, I have one concern. There are many footnotes saying if you downgrade from 4.4.2 to a lower version, you will brick your phone. These footnotes don't specifically say whether they're talking about OS version or baseband version. Is it safe for me to upgrade to 4.1.2 -> 4.3 -> 4.4.2 with a 4.4.2 ROM? Is it safe for me to flash a 4.1.1 stock ROM?
Any help appreciated. Thanks!

first if wanted , i would get the free unlock sim code (am pretty sure is available on 4.1.1).
all i have ever read says to do the incremental updates (safest).; which i believe you can do OTA ; or flash thru recovery.
yes , you will most surely brick your phone if you try to downgrade bootloader from 4.4.2.
AND you want to keep bootloader and baseband at the same version. upgrade one then upgrade the other.
if your already on 4.1.1 , then yes flash away the stock 4.1.1 rom ; if youre talking about after you upgrade to 4.4.2 then the 4.1.1 may not flash unless you edit the updater script (think thats what its called , been awhile).
good luck !

This is an I747, right? I think the I747M had LK3 firmware too. If you happen to be on an I747M don't flash any of the I747 specific stuff below, or you'll probably brick your phone.
Since you're still on the old firmware it might be a good idea to carrier unlock your phone if you haven't already done it. You'll lose that ability if you update.
To update to 4.4.2 firmware you can go two ways. You can Odin back to unrooted stock and you should start receiving OTA updates. They will be incremental and they'll come about 24 hours apart, or you can set your system time ahead a day to cheat that. Eventually you'll get up to the 4.4.2 firmware. NE4 is 4.4.2, but NJ1 is the most recent. This is probably the safest way, but it will be somewhat slower. Those OTA's are full firmware packages so they're big downloads.
Or you can flash bootloader/modem only upgrades in custom recovery. Enewman17 has posted everything you need to get an I747 up to date to XDA. I flashed all these while running the Slimkat stable 9 ROM to get my I747 from LK3 up to NJ1. This has to be done incrementally and you have to boot successfully into your ROM in between each firmware flash. You can't jump from the 4.1.1 bootloader to the 4.4.2 bootloader. First flash the MJB firmware update linked to this thread then reboot into your ROM. Next flash the NE4 firmware zip also linked to that thread and then reboot into your ROM. You're on 4.4.2 firmware at this point, but if you want to be on the newest bootloader and modem then flash the NJ1 zip attached to this thread. If you go this route be sure you read enewman's posts very carefully and understand exactly what you're doing because fiddling with the bootloader and modem is the #1 way to hard brick this phone.
For the most part you can flash any ROM you want no matter what firmware you're on as long as it is intended for I747. You might find that your wifi won't work or your modem doesn't work or maybe it just bootloops if you get on a ROM that wasn't intended for the bootloader/modem currently on your phone, but you can still boot up into recovery and restore a backup or flash another ROM and get out of that. What you have to be very, very careful with is the bootloaders since Knox was introduced, that's MJB, NE4, and NJ1. Those bootloaders cannot ever be downgraded; don't try it. You'll hard brick and it is pretty hard to recover from. Its also for the best to keep your bootloader and modem matched on this newer firmware; the OTA method or the zips linked to the threads above will do that. Custom ROMs that are AOSP/CM based won't ever mess with your bootloader and modem. They're just a system image and a kernel. What you have to be really careful with is Odin, those are usually full firmware packages. AT&T hasn't allowed a stock image beyond 4.1.1 to be released for the I747, so once you're on the newer bootloaders there is no more option to Odin back to stock.
Good luck.

If you are still on the original bootloader and modem you should be able to revert to stock 4.1.1 by simply restoring the backup from your recovery. Before you attempt to do so verify that you are indeed on the 4.1.1 bootloader. This can be done with the Phone Info *Samsung* app by VndNguyen (?sp) from the playstore or by a couple of terminal emulator commands:
Code:
getprop ro.bootloader
getprop | grep version.baseband
If you do not already have terminal emulator installed, it may have come with the ROM, you can get it from the Playstore. It may also be a part of CWM recovery, it is part of TWRP I know for sure.
If it turns out you are on a newer bootloader and modem then go with a stock ROM that matches the bootloader and modem on the phone. To run a lollypop rom you will need to be on at least the NE4 bootloader and modem.
Thanks for a very helpful reply. I m going to follow your instructions. Will soon replay. Thanks again.

Okay got Samsung phone info app.
Boot loader version -------I747UCDLK3
Baseband version -----I747UCDLK3
And please explain LATEST NE4 BOOT LOADER.
Thanks
You are currently running the LK3 bootloader and modem. If I am not mistaken that's a pretty old one (original?). You will have to update to NE4 or newer firmware before you can flash any of the newer roms. They will not boot in the older ones.
Your firmware is actually the only one available for download so I recommend flashing it via Odin and factory resetting. Then update using the Software Update option in Settings > About Device.
You can download your LK3 firmware here: http://www.sammobile.com/firmwares/database/SGH-I747/
You may have to run Software update several times to fully update.
That is probably the safest and easiest course you can take.
After that, flash the latest custom recovery of your choice, then flash the rom you want.

BTW, after flashing the LK3 firmware, you might want to consider using the free Sim unlock method. (Should be pretty easy to find).
Once you update past 4.3 you can no longer use it. It will allow the device to be used on other carriers networks, which can be beneficial if you ever want to sell it or switch carriers.

What DocHoliday77 suggests is probably the safest method to get what you want. After each update the system will force you to wait 24 hours before you can make the next update. That would be three days to get to NE4, the first 4.4.2 release by AT&T, which you need to run lollipop ROMs. If you want to update to the current release (NJ2) that would be two additional days.
You can shortcut the required waiting period by manually advancing the system date after each update.
In addition to not allowing you to use the free unlock, once you take the 4.3 bootloader it prevents you from downgrading bootloaders. Newer bootloaders do the same, downgrading will be a thing of the past. (I never took the official 4.3 bootloader until the stagefright scare came along and I went from my older custom ROM to a new release.)

1:- Okay I fully understood what I have to do to flash lolly pop . But confused a little bit . If I have original boodloader than it should be easier to restore my stock 4.1.1 . Backup (still not clear) .
2:- I am out of USA. The device in unlocked. I am using ZONG sim on it. So the question is can I still update the device via OTA.
Thanks

When you say original bootloader I don't know which you have. My i747 came with 4.1.1 but before I could get it out of the clerk's hands they had taken the OTA to change it from DLK3/4.1.1 bootloader and stock rom to MG2/4.1.2 bootloader and stock rom. Even more confusing I have read reviews that state the SGS3 was originally released with android 4.0.4.
If your original bootloader was older than 4.3 (MJB) AND you have never upgraded to MJB or newer, then you can safely return to stock 4.1.1.
To get OTAs you need to be on the stock ROM, at least you do in the USA. I don't know if that holds true elsewhere.
I can confirm the S3 was originally shipped with 4.0.4! We were updated pretty quickly though.
As for the OTA'S, you do have to be full stock, not rooted. But you also have to be on AT&T network.
I don't know how far back the OTA'S are hosted around here, but enewman17 has several threads that provide the more recent ones. Hopefully someone will have the older ones. If I am not mistaken, you will have to update incrementally once you reach 4.3. (it's probably safe to jump straight to a 4.3 build if you can find the right firmware for it. But don't hold me to that as I am not 100% certain.
I'll look to see if I can find something you can use too.

Thanks men for quick response.
now I m fully confused. Don't know what to do. because I don't want to stuck on this battery enemy rom. (Aokp kitkat. Custom rom )
I am not clear about boootader version (PHONE INFO SAMSUNG APP SAYS ITS i747ucdlk3 ) but I know when got this thing. It was android 4.1.1 . Which I have back a backup. As per I am out of att network and I can't get OTA,s so I don't need to revert to 4.1.1 backup. I think I have to find out 4.3. For my device. So kindly please inform me if some one knows about . Iwill be very thankful to u people.
Again thanks

I got this while searching online. Please tell me if it is helpful for.me.
http://androidromupdate.com/att-samsung-galaxy-s3-sgh-i747-odin-stock-firmware/
Never been to that site, but it looks OK to me. Nice find in fact! All the usual firmware sites stopped getting the AT&T firmware a while back.
Anyway, just to clarify, LK3 is 4.1.1. UCDLK3 is just the build number.
If you want to get fully updated, I suggest Odin flashing the MJB (4.3) firmware. Then flash each of the OTA's until you are updated to where you want to be. (I would fully update, but that'll be up to you.) The OTA'S are intended to be flashed from stock recovery, but there is another option if you want to try it. Mobile Odin is an app by chainfire. It does require you to be rooted, but it will flash the OTA. Read his thread here on xda to learn more. It's one of my favorite apps tbh! Once you learn how to use it it makes flashing quite easy.
So my recommendation would be this:
Flash MJB with Odin.
Root using Towelroot (easiest root ever)
Install Mobile Odin and flash the OTA'S.
I hope that clears things up a bit!

Update:- I am stock 4.1.1 now . I restored the device from custom AOKP kit kat rom using the stock 4.1.1 backup which I have made via CWM recovery. The device is running perfectly.
*****tried to run OTA but it says ur. Device in up to date . Means I cant get any OTA up date . So the question is can I get any custom lollypop rom using this older bootloader. ? (LK3)

To be able to run a lollipop rom you will need to update bootloader and modem. Update them together, this is important once you reach the 4.4.2 level of bootloader and modem that you will need to run lollipop roms. Once you reach 4.4.2 you will brick your phone if the bootloader and modem versions are not the same.
Before starting to flash any of the files you need to get you up and running on lollipop, I strongly suggest you download all you need from start to finish. Store the files you will need in the upgrade process either on an external sdcard or on the root of your internal sdcard. I haven't used CWM Recovery on my SGS3 since shortly after rooting it, I have been using TWRP since then, and I don't recall all of the capabilities of CWM recovery. If the CWM version you have will not let you flash from an external sdcard you will need to store the files you will use on the root of the internal card to be able to flash them. It will be easier to do this before you start, unless you are comfortable with pushing files from a computer using adb.
BEFORE DOING ANYTHING I AM SUGGESTING read enough that you thoroughly understand what I am saying. After reading, ask questions for clarification. Be sure you have no doubts.
Decide if you intend to install a rom along with the bootloader and modem at each upgrade; or if you are going to install updating only bootloader and modem until you get them to them point that you can run a lollipop ROM. Since you said you can not do OTA updates, either way will work. Whichever you decide, you can not skip directly to the bootloader and modem you need for lollipop.
If you are installing bootloader and modems without the rom:
From the stock 4.1.1 rom and bootloader you can go straight to 4.3 bootloader and modem, skipping the 4.1.2 (MG2) version. I have personally done this with no ill consequences. After 4.3, install the first bootloader and modem version for 4.4.2, that is NE4. Lollipop will run with the NE4 bootloader. As DocHoliday stated, you can go on the the current bootloader and modem. After NE4 is NJ1. After NJ1 you come to the current bootloader and modem, which is NJ2
If you plan to install the full ROM at each step.
The page you linked to should work if all of the downloads are available. Go from 4.1.1 to 4.3 to 4.4.2 (NE4). If you want the newer versions (NJ1 or NJ2) do them in sequence, do not skip any that are mentioned. Read the instructions on your linked page carefully. If you want NJ1 and then NJ2 they can be found in threads by enewman17, as can NE4 and maybe 4.3. I didn't provide the links so that you will hopefully read the pages carefully after searching and before downloading. Be sure you understand what you are downloading to flash and how it should be used.

Thanks **** I need to be extra careful before taking any step. I am going to collect all relesed OTA,s. By now I onky need the links for ota. Thanks
Flash MJB and NE4 from the site you linked to above. Then use enewman17's thread for the NJ1 and NJ2 updates. He also has NE4, in case you want to get all the OTA'S from him. (Downloads will be a lot faster) They've all been used many times. I'll try to post a direct link in a few...

I got this site having all ota, s . And is linked to the enewman17.
www.androidayos.com/samsung-galaxy-s3-stock-firmware-2/
Lol, I guess they thought they had to provide it somehow! It's a shame they didn't at least acknowledge enewman17 in their article there, but at least they direct linked to his thread.
Anyway, good luck! And if you have any other questions come up, let us know.
