SpellingHello,
I rooted my 4.1.2 SGH-T999 by CWM , then unlocked it by downgrading the modem , unlocking and then upgrading to 4.1.2 .
When I checked for OTA updates the phone says" my device has been modified. software updates are not available. "
How can I get back the option of getting the OTA updates? If so, will I lose root? And also while I am on 4.1.2 is there any things else I can do that are simpler to do than when on 4.3?
Thank you.
May I suggest first reading up on the serious issues caused by accepting OTA updates. If you still really wish to go down that path, then use Odin to go back to stock before accepting OTA.

I guess since the phone is out of warranty and kind of old, it probably won't get that many updates in the future. In that case, I can leave everything as is.
With the configuration I have now: Unlocked at 4.1.2 , CWM 5.5.0.4, how do I update the phone to the latest one available on this site? Do I use odin ( PDA and which flags ) , or load it in SD card and run it from recovery? Doing either one, do I lose root or not, and how to get it rooted again, same way I did it the first time.?
Thank you guys for your assistance , this is the first time ever I am making changes to a phone.
StockMod Rom comes as a Zip. Put it on SD card and Flash via CWM. That's not CWM's latest version.
So if you keep getting errors (Status 7) while trying to flash, then you will need to update CWM.
Latest is 6.0.4.5 over here. Alternately, get Rom Manager to update as well.

Would I lose unlocked if I flash the modem and use Stockmod or Stockmod Custom ROMs?
Do these ROMs come with WiFi tethering?
I am slowly learning, Installed ROM manager from AP store, and updated the CWM to the latest..
I have to flash the modem first, should I reboot then Flash Stockmod or do both one after the other?
Thanks.
I believe StockMod will support WiFi Calling. You will have to try and find out. As to the Modem, you can flash both one after the other and that's fine. When it comes to modems, I personally reboot after a modem flash to see how the signal is like.
Sometimes, some of the modem don't work well in my geographical area. If the modem is a precursor to the Rom, then I'd flash the modem, then check and then flash the rom. After Rom is up and running, I may go back to original modem.

The reason I asked is because on the development page where the Stockmod is , it says to " Flash T999UVUEMJC Modem
Flash ROM , Reboot and Enjoy "
My other question was about sim unlocked. I downgraded modem, did the unlocked routine, upgraded back to 4.1.2 modem. Now if I flash modem and ROM, would the SIM Unlocked status stay or I have to unlock all over. The whole reason I got here was to unlock and root for WiFi hotspot.
Thank you again for walking me through this.
The phone will stay unlocked despite change of modem or Rom. You can try flashing the rom directly without the modem. I don't think there may be issues. Of course you can flash modem if it didn't work. Put the modem on your external sd when you download Rom.

It doesn't matter.. But you do need the new modem or you won't pick up signal on 4.3

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?

Bootloader = I747UCDLK3

Yes I get data when I load a backup of CM 10.2.1
Thanks
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.

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.

I appreciate all the help you can give me. Thank you. (sorry for my english)
Does your sim card have a pin code that you enter each time you boot the phone? If yes, does the phone ask for the pin before unlocking the sim? What bootloader and modem are currently on the phone? Did the phone work before installing a custom ROM?
@audit13 , mine said "no service available" after moving from KK to lolli and i flashed a "write to extsdcard fix zip" and it fixed the issue , i.e. can now make and recieve calls. dont know if is same issue (or why exactly that fixed mine) but i have a KK "write to extsdcard fix.zip" if you think it would help.

The problem is the bootloader and modem. They need to be updated to work with the latest ROMs.
If the phone is sim unlocked, I recommend flashing back a stock rom using Odin and the firmware from sammobile, set up the phone, run ota updates until the phone is running the latest bootloader and modem. This is tedious and takes the most time but it is the safest method in my opinion.
If you don't want to go this route, just flash the latest modem and bootloader using twrp, flash the custom rom, flash gapps.
@Budare , here is the thread to upgrade bootloaders and modem if you decide on this route rather than flashing back to stock and running ota updates as @audit13 suggested , which IS the safest route. (always always always a certain % of risk ; no matter how small , to flash anything. not trying to scare you , just being honest)

thank you audit13, but how i run ota updates??
To run ota updates, you need to use Odin to flash the stock att 4.1.1 rom using Odin. After setting up the phone, check for software update under the phone settings.

i dont know if is because im in Madrid, but the phone doesnt get updates, thats why i want to use another rom. what can i do?
Not sure but I have received OTA updates even when the phone is not in the phone's original country. The OTA updates came over wifi.
If you want to use another ROM, you can install TWRP, boot into TWRP, flash bootloader, flash modem, flash custom ROM, flash gapps. If flashing the modem bootloader in TWRP, DO NOT reboot the phone in between flashing this files and make sure the bootloader and modem version are made for each other.
