reverting to 4.1.1

i have the s3 att on a 4.4.4 CROM. the baseband says ...LK3. can i use any guide using odin to go back to 4.1.1 stock unrooted and then use OTA updates to get the latest baseband/bootloader/modem? just want to make sure before i do it. i hear this is the safest way and i want to make sure i have met the requirements before i do it so i dont end up having a brick! (not sure if it matters but i have never used OTA updates before)
thanks in advance.

Is your bootloader also the lk3? If the modem and bootloader are lk3, you can use Odin to flash back to stock using firmware from sammobile.com.

Ok, I'm on a similar boat. I tried several AOSP based ROMs, and while I like most of them a lot more than stock touchwiz, they all present the same problems:
- Camera stops working sometimes and I have to reboot device;
- Camera won't record videos in 1080p, even when it's selected in the settings;
- Cannot make video calls on Skype longer than 5 seconds before the call drops;
- Disconnecting a bluetooth media device while music is streaming causes sounds to stop working;
- Tap to pay doesn't work at all;
So because of these problems, I want to go back to stock . My phone is the AT&T version. Currently I'm running Carbon Rom with KitKat 444. The baseband version is I747UCUFNJ1. The latest version of the stock ROM available on sammobile is:
Version: Android 4.1.1
PDA: I747UCDLK3
CSC: I747ATTDLK3
MODEM: I747UCDLK3
Would I be able to revert my phone back to stock with Odin? If not, what would I have to do to revert? Am I stuck with custom ROMs?
I'm pretty new to this so I'd appreciate anybody's help.

If your bootloader and modem is the lk3, you should be able to Odin back to stock 4.1.1.

Ok, how do I find out if they are? And if they are not, do I have any other options?

Download and install the Samsung Info App from the Playstore. Report back here with your bootloader and modem.

someone correct me if i'm wrong.you cannot downgrade bootloader or it will brick. there is no stock rom for NJ1. this link will take you to a stock based 4.4.2 ROM which is safe to flash with the NJ1 bootloader/modem.

Well, that's a bummer if I can't restore stock rom to the phone. So there is absolutely no way of safely downgrading the booatloader?

nope. it will brick your phone if you try to downgrade your bootloader.

Have you tried CM-11-based or TW-based ROMs?

I tried to push that ROM the phone using adb to flash it with ClockWorkMod, but the file is 1.7 GB and the phone always shuts itself down during the push process... So I wasn't able to try that. Also, the instructions say you're supposed to be on UCUFNE4. Are you sure it's safe to flash it on I747UCUFNJ1?

I have tried CM11 and Carbon ROM, which is CM based, both have all the same problems. I haven't tried TW-based ROMS. Do you have any suggestions?

What do you mean by the phone shuts down? Did you try copying the ROM to a microSD card?
Did you notice any bootloader or modem files in the S3Rx 4.0 (11-9-14) ROM? It may not include a modem or bootloader. In step 1 of the flash process, it says "AT&T I747 users should update bootloaders and modem to NE4 http://forum.xda-developers.com/gala...pdate-t2808654 I747M and T999 users need to be on 4.3 firmware or ROM will not boot. "

the link i posted is TW. post #1306 claims is o.k. to flash with UFNJ1.
did not see any mention of bootloader or modem in changelog or in list of 'extra' features.

I reboot the phone in ClockWorkMod recovery. Then I go to the command prompt and type:
Code:
adb push S3Rx_UCUFNE4_AROMA_11-9-14.zip /sdcard/
It starts pushing the file to the phone, but after a while, the phone screen goes black, and I get a "Protocol failure" on the command prompt. After this the power button no longer works, I have to do a battery pull for the phone to work again. The phone has 10 GB of storage left so it didn't run out of space. The USB chord is brand new so I don't think it's that either. It worked fine before when I pushed other smaller roms.
In another question, would this process allow me to downgrade the modem and restore stock rom?

i am pretty sure that since youre on MJ1 , your bootloader and modem have to match.
"all i can really do , is stay out of my own way and let the will of heaven be done"

Did you try flashing the card from an external microSD card?
AT&T never released a stock ROM for the i747 beyond 4.1.1 afaik; therefore, you cannot get back to stock unless you flash an OTA ROM that has been compiled for flashing in Odin.
I do not recommend mixing and matching bootloaders and modems as a mismatch may result in a hard brick.
Downgrading only the modem will not allow you to flash back to stock.

So you're basically telling me I'm stuck with custom roms unless I find a 4.4.2 OTA ROM I can flash with Odin (which doesn't appear to exist)?

Would it be safe to try this:

Even though I'm on I747UCUFNJ1 and not on I747UCUFNE4?

Once you upgrade to the 4.3 or newer bootloader on the i747, you are stuck with either custom ROMs or OTA ROMs that have been compiled for flashing in Odin or CWM/TWRP.
You can try flashing the NE4 ROM because it doesn't appear to include a bootloader or modem. The first post says "Prerequisites include a minimum of a 4.3 bootloader and modem.
If you are not on the official 4.4.2 bootloaders and modem then you will need to flash ktoonsez kernel."

Thanks audit13 and mrrocketdog for all the help. I was able to get the AROMA rom installed on the phone. All functionalities lost with AOSP ROMs are back working so that's a plus. Still can't get updates OTA updates but this phone is probably not gonna have any new ones. Still hopeful that lolipop based AOSP ROMs fix the problems I had, but I'm not holding my breath.

[Q] APN not listed and cannot add

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

What is your bootloader and modem? Do you get data if you re-install your previous ROM?

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.

Which variant of the galaxy s3 do you have? You should be able to flash any ROM compatible with your phone using TWRP or Phil touch recovery.

I have the i747m (rogers canada). I have TWRP 2.8.7.0 & rooted with Kingo root. Somehow it was the only way to root it. Tried Towel root & odin but both were doing nothing.
TWRP was installed a long time ago. I recently made an update on kies (what a mistake sign...). I was on 4.4.2 before and after the firmware update on kies.
I got a spare S3 motherboard (with cpu etc.) I might try on that one first but I need to disassemble & assemble everything... not very tempting.

I usually just use odin and http://www.sammobile.com/firmwares/ to start fresh and root again when I want to upgrade bootloader and modems.

As you saw at sammobile, OB3 is the latest official release for the i747. You do not need to do anything to your baseband (modem) to run CM11. You may want to verify that your bootloader (firmware) matches the modem. This can be done from within TWRP. Go to the advanced menu and in the terminal enter
Code:
getprop ro.bootloader
You should get a return ending in OB3.
I suspect the CM 11 updater-script has not been updated to account for the just released OB3 firmware. If that is the case, you could always edit the script in the roms zip file.

@dawgdoc
When I entered the command, it returned me:
I747MVLUFOB3
Secondly, I have not tried to install CM11 (or the newer version CM12?). I do not know if it works. I just want to make sure I can flash and not brick my phone.
My phone is not the d2att (i747), it is d2can (i747m). I believe these two are very similar but enough different to cause problem.
So, can I install CM11 or 12?
You are talking about changing a zip file... The newb I am know how to do that, but what exactly - that he doesn't know. So I would rather not mess with that. I guess TWRP checks if the firmware of the bootloader / modem matches to those from a compatible list and simply updating that list would allow me to install the build?
I was thinking about this ROM:
http://forum.xda-developers.com/galaxy-s3-att/development/unofficial-cyanogenmod-12-t2968854
Don't know the exact difference with the CM12 but it says d2can.
However, the BaNkS GAPPS - GAPPS link does not work... I don't know what that is.

The unofficial CM12 -5.1.1 by @matrixzone is good for the i747M, aka d2can. If you have any doubts, ask on that thread if it is updated to run on OB3? Matrixzone is active on the forums and should respond to your question. Also I just checked the updater-script for the latest CM11 official nightly and it is set up to run on the i747M.
So, either should run with no problems for you.

What is the bootloader and modem version needed and how do I get them without getting a locked bootloader? I'm on i747M with 4.1.1 Stock rom with DLK4 modem and bootloader. There are newer bootloaders and modems that can be flashed through recovery but some people have been getting bricks when messing with bootloader.

[SOLVED] I think my i747M may be soft bricked?

Hey all. I am fairly inexperienced when it comes to rooting, though I have done a few succesfully in the past. I currently have the newest version of TWRP installed on my Samsung I747M. The I747M I have is not from one of the major carriers, but as far as I am aware, the phone is factory network unlocked. Carrier is GCI, in Alaska.
I currently have a 4.4.2 Touchwiz Rom installed and started having problems after I attempted to flash the ROM Dandroid, which is 4.3 (http://forum.xda-developers.com/showthread.php?t=2121506). I had created a backup using TWRP before flashing the ROM and reverted back once I noticed the problem.
The main issue I am experiencing at this time is the Baseband Version, IMEI, and other information related to the modem is showing "Unknown" and features such as wifi will not toggle on.
I had also attempted to flash the most current version of the modem that I was able to find thru Odin. Odin showed the flash as successful. The version I flashed to the phone was I747MUMUEND3: modem_CWM_I747MUMUEND3.zip - 18.80 MB - April 3rd, 2014 (http://forum.xda-developers.com/showthread.php?t=1831898)
At this point, I can still get into recovery, download modem and I am able to boot up the phone and access most all functions. The next step I was going to try was going to be to flash back to stock firmware from sammobile's website (Was using to use the Roger's version of 4.4.2), though I don't want to cause more issues than I can handle or resolve thru software.
Any advice on how to proceed would be greatly appreciated or even just how to get the modem/wifi features functional again would be helpful. I'm just as happy staying on my current ROM at this point if I can get the phone fully functional again.

It's possible that the rom is not compatible with the kk modem and bootloader.
Flash cm12.1 to see if your imei comes back.

Forgot to mention, this is something I did try. I attempted to flash Cyanogen Mod 12.1 (Download: cm-12.1-20151017-NIGHTLY-d2att.zip (286.76 MB) ) and most recent nightly build & the most recent stable release (CM11) (Download: cm-11-20140210-SNAPSHOT-M3-d2att.zip (194.37 MB) ). When flashing these, I transferred the downloaded ZIP file to the internal storage of the phone in the root directory and attempted to run an install from TWRP. Both installs failed.

Since the phone is an i747m, I recommend flashing back to stock using Odin 3.07 and stock ROM file from here: http://www.sammobile.com/firmwares/database/SGH-I747M/
The i747m versions are interchangeable between Rogers, Telus, and Bell.
After flashing back to stock, install TWRP using Odin 3007 from here: https://dl.twrp.me/d2att/twrp-2.8.7.0-d2att.img.tar
Create a nandroid backup using TWRP and then try to flash a custom ROM again.

The i747m versions are interchangeable between Rogers, Telus, and Bell.
After flashing back to stock, install TWRP using Odin 3007 from here: URL REMOVED FROM QUOTE DUE TO NEW USER LIMITATIONS
Create a nandroid backup using TWRP and then try to flash a custom ROM again.

I'll give that a shot when I get home. Stock firmware was one of my next thoughts. I have it downloading at the measly 15 Kbps offered for free from sammobile so hopefully should be done by the time I get home & update this thread with any progress.

Another possibility is a custom kernel, if you are wishing to stay with TouchWiz and not wanting to upgrade your bootloader and modem past 4.3.
Some of the 4.4.2 TW roms will run on 4.3 bootloader and modems using one of ibuddler's kernels or ktoonsez's TW kernel. This was discussed most in the Likewise ROM thread and links to the various versions of ibuddler's kernel may be found there. It may have also been discussed in TMS3KK thread. The ktoonsez kernel can be found in its own thread.
But, you may really want to consider a newer ROM in order to change to something with the stagefright fixes. I think any of these may require the latest 4.4.2 bootloader and modem. (What say you @audit13?)

I'm not opposed to any of this. Mostly just trying to slim down this phone to the basics as much as I can and am quite open to any recommendations. Main thing I want to maximize is battery life & simplicity since this is for my wife and those are her major wants in a phone. I figure any kind of ROM that just covers the basics should cover my bases & would prefer one with a darker/black skin to maximize battery life w/ the OLED screen. I am in the process of flashing to the Roger's stock ROM as I type this w/ my fingers crossed.
Just to add, no over clocking or anything of that nature is desired. If I remember correctly I ended up putting the ktoonsez kernel on one of my handsets, either this Galaxy S3 or my Galaxy S5, though I can't recall which since it was so long ago.

Alright! So progress! Wifi, Baseband version, IMEI and all other missing information restored & now works w/ stock rom flash. In process of reflashing TWRP now.

Let us know what happens.

Still all good with TWRP installed. Have not flashed back on a custom ROM yet. After reviewing some of the above recommendations, I am kind of liking the looks & features of TMS3KK (http://forum.xda-developers.com/showthread.php?t=2725750) and feel it would suit my needs.
I factory reset, cleared cache, and cleared Dalvik thru TWRP & then made a back up. Prior to this, I confirmed everything was still working normally w/ phone fully loaded after TWRP was installed.
One of the things mentioned on the installation instructions for that ROM is the following:
---
Do not mix and match 4.3 firmware (bootloaders/modem) with the new 4.4.2 ones. You will hard brick and I warned you. This works the same as any 4.3 or ND8port ROM with 4.3 firmware and it can use the new 4.4.2 ones also.
Link to recovery flashable i747 and i747M 4.4.2 bootloader and modem packages: http://forum.xda-developers.com/gala...hable-t2856914
---
How would I go about confirming my current bootloader/modem versions to make sure they are both 4.4.2 before flashing this ROM? At the link provided, those files/links to the files were removed because they were causing some bricked devices per a note at the top of that thread. Here's a link to the thread I am referencing since the above link looks to be broken. (http://forum.xda-developers.com/gal...mware-ne4-ne6-nf2-recovery-flashable-t2856914)

If you flashed the latest stock rom, you are running the latest 4.4.2 bootoader and modem.
You can download and run the Samsung phone info app from the play store to confirm this.
You should be good to flash any d2lte or d2att rom.
I recommend not flashing any modem or bootoader from this point forward unless the bootoader and modem are newer than the currently installed botloader and modem. Also, the botloader and modem must be matched to each other.

Thank you so much for the help and information. I guess I never realized that the bootloader & modem were installed w/ the stock rom as I always have flashed those separately through Odin when needed. Definitely good information to have and not easy information to find. I have successfully got my custom ROM on there and am now fine-tuning it for the wife.

Glad to hear the phone is running well.
I've heard it said "Happy wife, Happy life."

Return to Stock From CM12.1

I'm currently running CM12.1 on my phone. I love it, but I want to return to stock and give my phone an "out of the box" feel, and return it to the way Samsung made it to be.
I follow the typical instructions found here, but I always get an error (no screenshot available. Sorry!). I'm running Windows 10 and I have the proper drivers installed. Is there something I'm missing?

If the phone is running a 4.3 or newer bootloader, you cannot flash back to stock using a stock rom from sammobile.
Before flashing anything, I recommend verifying the bootloader and modem before flashing anything else. An improper bootloader and modem combination could brick the phone.

Alright. Thanks. A bit disappointed, but thanks anyway. Besides, CyanogenMod isn't bad.

I was just running CM 12.1 / 13 and I was able to revert back to Roger's Stock ROM Android 4.4.2
Try Odin3 and installing the stock rom. But you should always verify the bootloader.

If the OP is running the i747, it is the the AT&T version of the s3. AT&T never released a full firmware release for use in Odin after 4.1.1. AT&T only released OTA updates that upgraded the phones from 4.1.1 to 4.4.2. In order to flash a stock AT&T 4.4.2 ROM, it needs to be done from TWRP.
