I have a Canadian Galaxy S3, on 4.1.1 DLK4 Official. I rooted it, and have TWRP.
I want to upgrade my rom to a CM12/13 but of course with root and custom recovery, OTA updates are blocked.
I need newer bootloaders and modem to run the newer android versions.
Should I install them now, while on 4.1.1, and then flash CM12, or should I sequentially update each of the AT&T firmwares until I get up to 4.4.2?
Do official roms have the bootloaders and modems in them and install them automatically?
Should I use the Kies restore method?
The Canadian and att s3 phones are not the same model number. Don't flash an att bootloader to your Canadian phone as this may brick the phone.
Flash latest stock rom from Sammobile.com, flash twrp, flash cm.

Okay, but i can use AT&T roms tho?
The i747m will work with d2can, d2lte, and d2att Roms.
Is it safe to flash straight from 4.1.1 to 4.4.2 using a sammobile rom? will i brick due to Knox bootloader and modem?
Can I flash it using TWRP?
If someone could link a tutorial that would be very helpful.
I keep reading stuff that says to flash the newer bootloader before flashing a 4.3 firmware, and some that say the opposite. Others say that people should incrementally update.
I want to go from 4.1.1 original with Root and TWRP, to CM13.
Thank you.
Yes, you can flash the latest stock 4.4.2 rom from Sammobile.com directly to your phone. No need to do anything other than backing up your data.

Now I just need to get the balls again to use odin. Flashing the custom recovery using the Universal Tool Kit that had step by step walkthrough was adrenaline rush enough LOL.
I could also use Kies, as that has 4.4.2 OB3 (telus), and also has "emergency firmware recovery" feature if a brick ever happens. Though ideally the only time boot.img gets flashed is only with Full Stock Firmware files.
I find kies to be unreliable when I have tried to restore firmware so I always stuck with Odin.

I rooted my dad's phone a while back ago so he can use tethering in case of emergencies etc. He recently got a smart watch and I wanted to updated it so that he can use it. But it has not been touched since that day. I essentially want rooted stock rom, I'm unaware of where to find that the closest I can find is StockMod kitkat. Which seems to not work on ATT phones? I just want to make sure that I don't brick his only phone on christmas. So is there something I should be aware of?
His model is SGH-i747
Baseband
i747UCDLK3
Build number
jro03
So how do I go about upgrading it? Can I just flash TWRP and flash any rom using TWRP?
I found this, so I should install new TWRP, then flash a specified kernel then flash rom? would this be safe route?
Some of the latest ROMs require a 4.4.2 bootloader and modem.
The simplest and safest way to get the latest bootloader may be to flash back to unrooted stock 4.1.1 and run OTA updates until the phone is running the latest KK ROM. You can then flash TWRP or CWM and a custom ROM.

Would this require flashing with ODIN? I just want it so that it works with root is not required anymore.
Yes, you would flash the 4.1.1 stock ATT ROM via Odin. I prefer Odin 3.07.
You cannot install OTA updates with root.
You can try flashing just the bootloader and modem but I prefer the long slow route of OTA updates.
I rather do it this way, manually so my dad can enjoy it today. I was wondering how can I update it's TWRP? it's at 2.3 but the TWRP manager keeps crashing when I update it.
I highly recommend the latest d2lte version of Philz Touch for recovery.
https://goo.im/devs/philz_touch/CWM_Advanced_Edition/d2lte/
Ok I ****ed up, flash that kernel and did whatever and bam ****ed up. Not working... ****, I still ahve download mode and Recovery but it will not boot into the OS. I get a flash of samsung and then nothing else happends...****
I decided to flash stock DLK3 in odin. Then let the updates take it course (my dad doesn't need root) Where Can I find the file?
The stock ATT firmware is on sammobile.com.
If you want root, OTA to the latest 4.4.2, install Philz, flash supersu via recovery.
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?

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

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)?

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.
Hi guys I need some information regarding to How to root, flash Custom ROMS, flash various Recoveries and if I want to revert back to full stock ROM whenever I want to how will I do it?
My device model is SGH-I747M (Rogers Carrier) and I've updated it to the latest OTA update 4.4 KitKat
I've seen may threads regarding to the SGH-I747 but all are for AT&T carrier but not any single for the Rogers carrier why?
Do you have any warranty left on your phone? Flashing a custom recovery will trip the warranty counter and change it from 0 to 1.

I haven't rooted/flashed nothing on my phone yet. All I'm just asking the question bro and yea I don't have any warranty for it
The easiest way to root, in my opinion, is to flash a custom recovery in Odin. After flashing a custom recovery, boot into recovery, flash supersu, boot the phone, allow supersu to update and disable knox. Then boot back into recovery, create a nandroid backup, and flash a custom ROM for the d2lte.
To flash back to stock, you can restore your nandroid backup or flash a stock ROM from sammobile.com. Just make sure to match the sammobile.com ROM with your bootloader.
The big difference between the i747 (AT&T) and the i747M (various Canadian carriers) is the bootloader and modem. They are NOT interchangeable between the i747 and the i747M. I haven't seen any of the custom ROMs for these SGS3s that flash bootloader and modem. Therefore any of the custom ROMS for the i747 will work with the i747M. Custom TouchWiz based ROMs are safe to use.
If the instructions for installing a ROM say that you must be on the NE4 or NJ1 bootloader and modem, the equivalent for the Rogers i747M are (NDx?), NF2, and NKx. From your original post I believe you are on the NKx bootloader and modem pair. This is good for any of the Kitkat and Lollipop ROMs. The only catch is that the updater-scripts for some of the older KK ROMs may not recognize the newest bootloader and modems. The ROMs are still good, it just takes a bit of work to get them installed. The same extra work would actually allow you to run a JellyBean (4.3) ROM.
Stock ROMs, those designed to return your device to factory condition (+/- root and +/- custom recovery), require much more care.
If you ever need to return to stock for your i747M, DO NOT flash a ROM that will down grade your modem and bootloader. Downgrading the bootloader and modem once you are at, or past, the 4.3.x versions will brick the i747 and I have read it will do the same for the i747M. If you can not find a stock ROM in the forums for the i747M you can find them at sammobile.com.
There are some stock ROMs available in the forums that include the AT&T bootloader and modem. DO NOT flash/install any of these.
There are stock ROMs for the i747 in the forum that do not contain bootloader and modem. These are safe for you, but BE CAREFUL. You do not want to mistakenly try to install one that does have the bootloader and modem
Also, do not flash a modem that does not match your bootloader in version number. This did not matter prior to the 4.3 bootloader and modem, it has ever since.
i have rooted and unlocked galaxy s3(i don't know if it is t999 or i747)the imei and boatloader are for t999 and the android build is i747mvldlk4 4.1.1 official rom and i want to flash new rom but i don't know what i have to flash (t999 roms or i747)please help me....
What does it day in download mode? What about the baseband/modem version?
Best way to know for sure is to install terminal emulator and enter this:
getprop ro.bootloader
You may simply have a T999 running on an I747 based rom. The two are very compatible when it comes to custom roms.
Since it sounds like you are on pretty old firmware, you will probably need to fully update it before flashing a newer rom. Just remember to only flash firmware for your model device. So if it's a T999 do not flash I747 firmware. Once updated you can then flash custom roms from either device.
(Also check the sticker under the battery to see what model it says)
baseband:t999uvdmd5 and modem board is msm8260a
What about the bootloader?
boatloader:t999uvdmd5
And just for good measure, check the sticker under the battery.
You are currently running on T999 base firmware with an I747 based rom, so you can be pretty certain you've got a T999 model.
You'll want to flash one of the two latest firmwares for the T999. (NC2 or OH1 if I'm remembering correctly) (note that some roms may not flash on the newest OH1 firmware if they have been updated recently, so you may want to go with NC2 to make things a little easier for now.)
After flashing your firmware, flash a custom recovery and then from the recovery flash your choice of rom.
Hope that helps and good luck!
thanks so much for help....but i want to ask about the files which i need to download when i flash nc2 firmware please(do i need to download any files for modem and kernel or this files are downloaded automatially with the firmware file??
When you are dealing with firmware, it includes everything, unless otherwise stated. Download and unzip the firmware package. Then flash the .tar.md5 file with Odin. Back up data first of course, just in case.
Doing this will give you a fully updated, stock, unrooted device. Reroot using Towel root, or flash recovery then a rom if you choose.
If you haven't already, I suggest reading the first few posts of my firmware thread (sticky in dev section). There's already a lot explained there.
does flashing t999uvuenc2 relock my mobile network..and if that will happens what can i do to unlock without code
Once the phone has been unlocked via code or the free method, the phone should remain unlocked after flashing ROMs.
Yup, the unlock is permanent. You can safely flash firmware, roms, etc.
ihave flashed cm12.1 d2tmo on my t999.but the features of camera like full HD video recording and face detecting were lost..can I restore them on this rom
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.

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.
