UCUFNE4 to UCUFNJ1 update 16 gig AT&T I747

The development for the AT&T I747 has been discontinued by the developer. Thank you for your support.
WARNING: YOU COULD BRICK YOUR PHONE
UCUFNJ1 4.4.2 incremental update contains firmware.... bootloaders and modem baseband.
MUST BE ON UCUFNE4 FIRMWARE TO CONTINUE!!! Guide can be found here. http://forum.xda-developers.com/gal...are-update-t2808654/post53984772#post53984772
This is the perfect time to use this update to return your S3 to stock for resale or whatever. Download and save these files for when you are ready to return your phone to stock.
*This is a rooted NE4 system.img, stock recovery.img and boot.img. The install script will format system and factory data reset. /media is safe.*
1. Flash restore zip in a custom recovery. CWM, TWRP, Philz. https://www.androidfilehost.com/?fid=95784891001611561
2. Boot your phone and go through setup.
3. Use triangle away and clear your counter. http://forum.xda-developers.com/galaxy-s2/orig-development/2014-01-15-triangleaway-v3-26-t1494114
4. *Optional* If you want a clean un-rooted phone for the update do this now! , Go into SuperSu >settings>full unroot.
5. Reboot your phone.
6. Search for the OTA in the about settings, download and let the phone update.
Or download this and place in the root of your phones internal storage. Reboot into recovery and select the update from update.zip https://www.androidfilehost.com/?fid=95784891001611091
Advanced users.
The original OTA cfg file. https://www.androidfilehost.com/?fid=95784891001611092
.cfg file goes in root/cache/fota
Rename the .cfg extension to .zip and you can rename it update.zip yourself or you can actually flash it in a custom recovery once renamed. if you choose not to use the stock recovery to update.
*You will loose root during the update* But the bootloader is not locked so you can still Odin your favorite recovery and flash SuperSU.
TWRP 2.8.1.0 Odin tar. http://techerrata.com/file/twrp2/d2att/openrecovery-twrp-2.8.1.0-d2att.tar
SuperSU http://download.chainfire.eu/589/SuperSU/UPDATE-SuperSU-v2.16.zip?retrieve_file=1
Once you flash your favorite recovery via Odin, you need to be ready to hold the Volume Up, Power and Home button combo when Odin reboots your phone. If you don't catch it, once the OS boots it will replace recovery with the stock version. Once SuperSU is installed your recovery will stick.​

Thanks enewman for writing this up.

Doing Vice Versa Method?
Just to be clear, what if my galaxy s3 is on UCUFNJ1 and I want to go back to UCUFNE4, I can still ODIN the custom recovery and flash SuperSU?

For the advanced users, should we be able to install the update without any issues? I saw in another thread that someone had installed but now their phone will not boot past the Samsung logo to anything other than a black screen.
Also, do we know what this update contains yet? Other than new bootloaders, removal of root, etc.

You know if your not wanting to return your phone to stock I really wouldn't mess with this update. Far as the user who couldn't boot... Idk I wasn't there to watch them update. This whole mess with the S3 is exhausting. We haven't got a real Odin release so I'm woking with what I can extract from my phone after updating. The system.img in ne4 zip is 100% stock except for root. So I know the update worked because I did it. Also not sure what was updated either... The kernel yes... Firmware yes, all the system apps get patched so without decompiling ne4 and nj1 apps and comparing them afraid I have no idea what the update fixes or improves.

Thanks for all you do for us S3 owners, enewman17.
If we upgrade to the new NJ1 firmware, and then flash your latest SRX Rom, I assume we cannot then use your "restore.zip" to once again go back to NE4 stock since we would be on NJ1 bootloader? If so, is there a way to go back to NJ1 stock if we later want to sell our phone?

Towelroot no longer works after the NJ1 update. Can the CF-AutoRoot still be used? The only version at http://autoroot.chainfire.eu/ says it's for 4.0.4.

Yeah, I saw that, but I never had a custom recovery before, that I know of at least, and I suspect a lot of other people finding this thread in the coming days are going to be in the same boat as me. They just want SuperSU so their favorite 1 or 2 apps that require SU can continue to work.
Has anybody tried CF-AutoRoot yet on the NJ1 4.4.2?

I can confirm this as a root method for NJ1. You were exactly right regarding immediately booting into recovery after installing TWRP thru Odin. The files provided in your links (TWRP 2.8.1.0 Odin tar. http://techerrata.com/file/twrp2/d2a....1.0-d2att.tar and
SuperSU http://download.chainfire.eu/589/Sup...etrieve_file=1)
worked exactly as stated.
A BIG thanks to you. I can't live without AdAway, TiBackup and Xposed anymore! The few days without root left me a little grumpy.
And regarding the NJ1 update as a whole...I THINK the baseband upgrade IS an actual upgrade. Since NE4, I always thought Wifi operated was somewhat choppy/throttled. THIS looks to have been improved back to ICS "standards". Re: voice, I've had a handful of dropped calls, broken up calls, and choppy data in low signal areas over the past few months on with NE4. Initial observations (albeit a tad premature) lead me to believe that this has improved as well based on a weeks worth of data use and a few calls in a "controlled" environment (the area and physical structure of my work office complex is not cellular signal friendly to begin with) I have also noticed that boot-up time has improved a bit as well. Thanks again for your efforts with the ATT GS3!

I flashed CF-Auto ROOT via Odin without success, unable to gain root access. Followed your instructions via TWRP and flashed SuperSu 2.16, my SGS3-i747 is properly rooted and functioning perfectly on UCUFNJ1. As always, thank you very kindly for all your valuable time, effort, hard work and guidance. Be well, sir!

What version of Odin do we need to flash that TWRP, or do you have a link handy?
I've seen quite a lot of different Odins out there and don't want to brick my phone by using the wrong one.
Any pitfalls to watch out for if using TWRP for the first time? I'm sure there is going to be a bunch of people having to do this now that both CF-AutoRoot and TowelRoot doesn't work anymore.
For me, personally, I just use root for AdFree and to edit the font fallback order to properly support Japanese instead of Chinese glyphs on shared Han-unified Unicode codepoints.

Use Odin 3.0.7
Not really any pitfalls to TWRP. It has an easy clean user interface and it works.
Once you have flash Super Su, in my how to ne4 update there is a flashable stock recovery. You just flash it with TWRP and once you reboot, stock recovery will be back on you phone.

Hi enewman17,
Thanks for your posts and work. I'm hoping you can help me get the new NJ1 update installed and rooted.
Here's where I'm at: AT&T SGS3 on rooted stock NE4, installed using your guides from back in June this year.
The OTA NJ1 update downloaded but failed to install (as did the NE4 OTA back then, I assume because I was rooted).
My phone still has the TWRP recovery from the previous update, so I was hoping I could install using the original OTA cfg file download from the "advanced" section in your OP so as to avoid factory reset, etc.
I downloaded the file, renamed to update.zip, and copied to my SD card. However, when I boot into TWRP and try to install it, I get an error after the system check, something like "assert failed ro.secure==1". I guess I'm doing something wrong, maybe I'm mistaken about how the original OTA is supposed to work?
Again, I'm trying to end up with a stock, but rooted, NJ1 firmware but hopefully without having to reset/lose data and settings on the phone. I don't really care right now about resale or making it look like I haven't messed with it.
Thanks for any help you can provide! Let me know if I can provide any additional details.

I am actually looking to do the exact same thing. Currently rooted, with a lot of the AT&T apps frozen via Titanium Backup.
Hope there is some way to accomplish this without returning to stock!
Thanks in advance!

cf-auto root, or flash SuperSU with custom recovery.

T999LUVUBNF4 Root
Hey, I've been trying to root my S3 running the T999LUVUBNF4 firmware, but I'm having trouble. Towelroot doesn't support it, I haven't seen anything about a Root66, and I've heard mixed reports on CF-auto root. Does anyone know if there is a workable solution yet? How would I go about flashing SuperSU? Thanks.

Okay I've recently just flashed the root66 firmware that gave me supersu and all that.
My question is... Where do i go from here?
How would i proceed to
1) Install TWRP?, which version as well? Is 2.8 d2tmo fine? Can i have some instructions whether i use TWRP manager(goomanager doesn't seem to exist anymore) or do i have to go into download and flash through odin 3.09?
2) Installing a custom rom? I want to install Paranoid Android 4.6 beta 5 for D2lte but i'm not sure how to go about it. I have already downloaded the rom itself but not sure how to proceed from here. Also, how would i get the working and latest version of Gapps? (Also, can you tell me how to install Cyanogenmod 11 for d2lte as well?)
3) What are some cool apps to get?
4) Which root apps/roms/softwares will brick my phone? I'm never sure which thing will work and which won't.
5) how do i install xposed?
6) How do i remove all the bloatware? and how would i got about flashing through my phone without using the computer? is mobile odin compatible with my phone?
My phone is the SGH-T999L and i have no idea if i have a locked bootloader and how i would go about and bypass the limitations of this locked bootloader

Please don't post the same thing on multiple threads. Not being rude but it doesn't help at all

Rooting SGH-T99L with T999LUVUBNF4
I've read most of the more recent posts, and it is still unclear to me how to root my T999L which is already on the T999LUVUBNF4 baseband and build. I've seen references to cf-auto-root (like serio22 above), but the T999 (which I believe works for T999L) is based on T999UVALEM, which is 4.0.4 ICS. I certainly don't want to downgrade that far. The latest firmware on the first page of this Root66 thread is T999L_UVUBNC1, and there was a post indicating better reception with the newer modem, so I'd rather not downgrade that either. If I flash T999L_UVUBNC1 will my baseband remain intact (BNF4)? Or should I wait for a pre-rooted T999L_UVUBNF4? Or is there a better way altogether to root my T999L/BNF4?
Also, for other n00bs reading this, it's pretty clear that towelroot doesn't work on BNF4.
Thanks!!

rooted Windmobile 4.4.4
anyone have 4.4.? for wind mobile what ever is the new one stock that is rooted ?

I tried flashing UVDLJC - UVDMD5 (latest OTA update) using Multiboot Recovery v2.2 - (twrp2.8.3.0)
When flashing directly onto blank partition, I got some error about missing build.prop, and so decided to try flashing on top of stock ROM.
Stock I have installed as Flash PureStock Rom + Secure UVAMB7 Kernel (from http://forum.xda-developers.com/showpost.php?p=43772060&postcount=3) -- again, in multiboot -- and tried installing OTA on top of that. Got "error executing updater binary in zip"
What am I doing wrong?
Thanks

slimkat v9 to stock tw
Please help me. I have a sgh-t999. I want to know is it safe to install stock tw t999_uvuenc2. I'm currently running slimkat v9. My baseband is t999uvuenc2 and my android version is 4.4.4 i really want my s3 to revert back to stock. Ive been asking to the roms posted in this unit if it safe to direct flash but i havent got a good advice. I really want the stock touchwiz. Pls help me.

Which firmware to use
After I un-bricked my SGH-T999 with the debrick image sdcard ( YAYYY), I was able to boot with the stock 4.3 rom again.
I reflash the root66 4.3 firmware hoping it could get the correct boot image back in place. However it got stuck at the Samsung logo.
So I went into stock recovery and did a wipe/factory reset. Now I can still boot with the debrick sdcard but I am back in JellyBean (4.1.2 T999UVDMD5).
Which firmware should I flash 4.3 or 4.1.2? And did I miraculously downgraded my firmware ( I thought it wasn't possible) ?

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?

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?

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.

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?
http://forum.xda-developers.com/showthread.php?t=1831898

i am pretty sure that since youre on MJ1 , your bootloader and modem have to match.

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] Help with going back to stock (from CM11)

Hey, sup?
I need your help, I'm trying to go back to stock firmware on my i747, currently I'm running CM11 latest snapshot.
Background: Some time ago, I accidently erased my imei. Took the phone to a guy who restored it but the phone doesn't work with 3G now, only 2G. So I wanted to try going back to stock firmware to see if that fixes the issue.
I tried downloading the CUEMJB file from here, but it doesn't work (keeps looping the same page) http://androidromupdate.com/att-samsung-galaxy-s3-sgh-i747-odin-stock-firmware/
Can you help me? Also, it is safe what I'm trying to do?
Thank you!

Triple check to make sure the imei displayed in About Device matches exactly to the one on the sticker under the battery.
If it does, and after you get stock working again, PM me and I can probably help.
As for the looping, do you mean the Web page? Just get the stock files from enewman17's thread. It's either in General or Development, can't remember for sure. Probably General.

Thank you. Yes the IMEI matches.
I was able to download the file.
Unfortunately, the thing didn't went ok. After flashing my phone is unresponsive, black screen, no more boot
If I connect it to the computer at this point, it tries to search for a QHSUSB_DLOAD driver. Not sure what is that, I think I bricked my phone.
I've seen some guides for unbricking by placing a sd card in the phone at boot but so far it haven't worked

Going to one of the 4.4.2 bootloaders and modems for your device may fix the issue, maybe without going back to stock. But I do recall that a return to stock has been required by many. If you are on newer bootloader and modem than 4.3, do not use a 4.3 (MJB) file no matter the source. As Doc said use one of the releases by enewman17 that you can flash in your custom recovery, NE4 is here. enewman17 also has threads for MJB, NJ1, and NJ2 stock ROMs; all of these are flashed in a custom recovery. With the i747 I have continually seen it recommended that you upgrade bootloader and modem sequentially, that is upgrade to NE4 before going to NJ1, and NJ1 before going to NJ2. I can provide links to enewmans other threads if necessary.
BTW, the 4.3 release was not a full rom, it was an update/patch. Files I have seen run 100 mb or less. If that is the file you want, and can use w/o bricking your device see this thread http://forum.xda-developers.com/showthread.php?t=2722660 Only use it if you are on 4.1.1, 4.1.2, or 4.3 bootloader and modem.
Another way to get a 4.3 Odin flashable update is here. You must be on 4.1.1 or 4.1.2 bootloader and modem to use this as instructed.

Can you get into recovery? If so you can flash the appropriate stock rom by enewman17.
Do you recall what bootloader and modem you were on? If you have TWRP as your recovery there are terminal commands you can use within the recovery to determine your bl/modem versions. This may also hold true for CWM and Philz Recoveries, but I don't know for certain.
If you can not get to recovery you may need to put a debrick image on an external sdcard to boot and then restore your device.

Yes sir. With the SD card method I managed to boot the phone. Yay!
I don't recall bootloader and modem unfortunately. I know I was using CM11 one of the latest snapshots for d2lte.
I have access to download mode. Screen reads bootloader RP SWREV:2
I have access to recovery (its a basic one though). Reads Android system recovery <3e>
What do you recommend from here?

That is the stock recovery. If you were successfully running one of the latest CM11 snapshots, you were probably on one of the three 4.4.2 bootloaders ( and modems ), they are NE4, NJ1, and NJ2. This would explain why the MJB (4.3) image you downloaded and flashed would soft brick your phone. It looks like that flash may be responsible for you being back on stock recovery, at best guess. Before anything else, do a factory reset from the stock recovery. This is frequently necessary to boot when going from a CM/AOSP LP rom back to stock.
Since you can get to download mode, I think the best bet would be to install a custom recovery. TWRP for the i747 is here, the top image is flashable with Odin while in download mode. Remember not to reboot from Odin. Instead remove the cable, pull the battery, then boot straight to recovery. Once you have TWRP loaded, boot into recovery and use the terminal emulator in it to determine bootloader and modem with these commands:
Code:
getprop ro.bootloader
getprop | grep version.baseband
Once you know the version of bootloader and modem you had been on, reflash that version from TWRP you will probably need the file on an external sdcard to do so. After this you can flash your rom of choice from TWRP, stock or otherwise. Since you were having imei issues go with one of enewman's stock roms, as @DocHoliday77 suggested. He can then help you with the imei issues if still necessary. Any other ideas Doc?

Ok, so
Bootloader = I747UCUEMJB
I don't get anything when running getprop | grep version.baseband in the recovery.
This is what I've done so far.
Booted w/ the sdcard trick (bootloader in the sdcard).
Installed twrp
Installed the following files:
AT&T_I747UCUEMJB.zip
d2att_I747UCUEMJB_bootloader.zip
d2att_I747UCUEMJB_modem.zip
d2att_Kernel_Stock_init.d_4_3_MJB_v1.0.zip
That brought the phone to life again (w/ stock 4.3). Then I flashed CM12 from the recovery. All went ok.
Problem is, I still don't have 3G connectivity, only edge.
What would you recommend try next?
Thank you

Alright, I was able to upgrade to UCUFNJ1 for both the bootloader and baseband. Still no 3G. Ideas?

Pm me. As I said before, if the imei is correct, I might be able to help. I can't do it here though because it's against forum rules to post the info publicly. (Too many people want it for illegal use).
When you pm me, include your current bootloader and baseband. (Just so I don't have to keep coming back here for reference). Also include how it was lost and if you know how it was restored.
I know you've already posted some of this, but I get lots of PM's so it'll help me keep track of everything without going back and forth between here and there.
Also, you need to be stock for this to work, so don't flash anything else just yet.
Glad to hear you got it running again BTW!

Question on upgrading bootloader and modem on i747

I currently have bootloader and radio at version I747UCUEMJB that I would like to upgrade all the way to I747UCUFNJ2.
Can I do a jump from MJB straight to NJ2 or I would need to upgrade sequentially ie MJB->NE4->NJ2?
Also, I found this website: http://androidromupdate.com/att-samsung-galaxy-s3-sgh-i747-odin-stock-firmware/ and it has the links to the NE2 and NJ2 firwares, however, the file's size is about 900MB. Does modem and bootloader really need 900MB or is the file actually bundling everything together ie modem+bootloader+ROM = 900MB?
If latter, where can I find working links that only offer the modem and a bootloader to be flashed?
Thanks!!

The safest way would be to use Odin to flash this full NE4 firmware update. Once you're up on stock NE4, you can take OTA updates. You'll go from NE4 -> NJ1 -> NJ2.
enewman17 has posted everything you need to update manually linked to this thread. If you go this route, read that thread carefully, then read it again and make certain you understand it. You have to update sequentially MJB -> NE4 -> NJ1 -> NJ2, and you have to reboot into system between every firmware update. Be super careful if you go this route. This phone is easy to hard brick when messing with bootloader and modem.

@jason2678,
Thanks for a reply. I was using this site: http://androidromupdate.com/att-samsung-galaxy-s3-sgh-i747-odin-stock-firmware/ as my main software source and the available android software goes straight from NE4 to NJ2. So just to double confirm, I can not make a jump from NE4 straight to NJ2, correct?
I tried to do OTA while on NE4, but I do not get any update push notifications. It says all of my software is up to date.

No, don't try to go straight from NE4 to NJ2. It needs to go NE4 -> NJ1 -> NJ2; the firmware order is in the bottom of enewman17's first post in his firmware thread.. Update the firmware sequentially, and do a full reboot into system in between each firmware update.
The full reboot part is faster if you are using a custom rom as you update because if you try to update firmware without updating a Touchwiz rom it probably won't boot.

I think I start to understand.
updates NE4->NJ1 and NJ1->NJ2 are not updating everything in the Android. Those are just some *incremental* feature enhancements to various facets of OS, bootloaders and modems; hence, it now makes sense why their size is so small.
Q. Does this mean I will not lose any personal settings/apps/etc in my already configured OR it resets and I will have to re-install the apps?
Also, can I use Android's recovery (Volume UP + Home) instead of suggested TWRP or CWM? is there a reason why we should do it through custom recovery?
Lastly, I read somewhere that both modem and bootloader must be of the same version. When I do 'adb bugreport', I get
Build fingerprint: 'samsung/d2uc/d2att:4.4.2/KOT49H/I747UCUFNE4:user/release-keys'
Bootloader: I747UCUFNE4
Radio: msm
However when I use PhoneInfo app, I get
Bootloader Version: I747UCUFNE4
PDA Version: I747UCUFNE4
CSC Version: I747UCUFNE4
Baseband Version: I747UCUFNE4
Latest Firmware: N/A
Q. What is Phone: msm? I thought Phone should be equal to I747UCUFNE4 as well.
Can I or can I not proceed with an installation of the NJ1 given my current spec?
Also, some random questions:
1) Will my present OS work with NJ1 or NJ2 ( I am currently on NE4) or do I need to update the OS as well?
2) if I need to also install the NJ1 ROM,
will I need flash bootloader first, reboot into NE4 OS, reboot again into recovery and install NJ1 ROM
OR
I have to install bootloader and ROM, all at the same time within the recovery without any reboots?
Thanks!

If you're running a stock rom, you need to reflash it at each step. With stock roms, you need to use the NE4 rom on the NE4 modem, the NJ1 rom with the NJ1 modem, etc. If you don't update the rom too, then it might not boot if the rom doesn't match the modem. Even if it does boot up, you'll likely have problems like wifi not turning on. I'm not sure if you can "dirty flash" those rom zips without wiping (and keep settings and app data), or if that will fail to boot. I'd search the enewman thread for help on that. When I used these I was running CM 12.1, so I didn't have to mess with the rom. Custom roms are more flexible than stock roms in what bootloader/modem they'll work right on.

Nope, an NE4 rom might not boot on NJ1/2 firmware, and even if it does boot up something will be screwed up like wifi not turning on or no mobile data. To make it easier I'd just flash LOS or OctOs before messing with bootloader/modem. LOS 14 should boot on any kitkat bootloader/modem (NE4, NJ1, or NJ2).
Touchwiz roms can be finicky about booting up sometimes, first boot will last 10 - 20 minutes on a new rom, and you don't want boot to fail in between these bootloader/modem flashes. To keep it simple and faster, I'd just run a custom rom like LOS while you're updating even if you go back to stock NJ2 once you're done and everything is up to date.

@jason2678,
Thanks for your reply with the details and adb how-tos. Adb confirmed that both my bootloader and modem are indeed I747UCUFNE4. Not too long ago I flashed NE4 (CP, AP, BL, CSC) via Odin and it was very encouraging to see the same results via adb.
From what I gather, all in all, the amount of risk/benefit ratio is quite high in the context of moving from NE4 to NJ1.
Yeah, I was on LOS14 before and it was very extremely choppy on my i747. OctOs was much smoother but the dialer would not open up and image processing (photo viewing) was not very good. So that is why I flashed everything to stock NE4.
Few more questions..
I see the link for the rooted NJ1 rom, but are there unrooted NJ1 Roms available or do I have to unroot myself?
If I decide to proceed to NJ1, do I install BL/CP and ROM at the same time or I install CP/BL first, reboot and then ROM?
I see that there are two flavors of NJ1 BL/CP. One is 68MB and the other is 19MB. Which one do I use?
Thanks,

Sorry, I'm entirely certain how to go about flashing those bootloader/modem combos with stock ROMs. Those details might be covered in enewman's thread. If I had to do it, I'd just flash OctOs and set it up first, so the reboots would be quicker and it would work with any of the modems.
I flashed that nj1 rom once. It's not actually pre-rooted. It asks if you want to root after it flashes system, so you can choose not to root it.
I don't know why there would be two different nj1's. Maybe one is just the modem and the other is bootloader and modem? I'd pick the one with both bundled. You always want them to match on this phone on the firmware with Knox. Only flash stuff enewman packaged. He's the man for i747 firmware.

Yes, for for sure - I want to use only enewman's packages. The thing is: in his post at https://forum.xda-developers.com/galaxy-s3-att/general/ucufne4-to-ucufnj1-update-t2941792
he lists two NJ1 bootloader/modem files from what I can understand.
1) 68MB https://www.androidfilehost.com/?fid=95784891001611091
2) 19MB https://www.androidfilehost.com/?fid=95832962473396872

Just burned TWRP over the stock recovery.
Tomorrow I will go to Samsung Experience center over at Best buy. I heard that they bring samsung phones to the most recent available updates. We'll see how that will go. If this route will not lead anywhere, then I will burn NJ1 and NJ2 myself.

So all is working right now and I am happy to have the most recent update. It was really interesting to observe how they do it. After they connected the phone via USB and clicked something on their computer, the phone went directly from GUI into download mode without ever rebooting. I suppose they have some keys that open up a whole range of options on the phone.
The only problem that I discovered, and this has nothing to do with an upgrade, is that kit Kat is missing WebView and Google no longer supports WebView for KitKat for 442. Looking for alternatives now....
Thanks again, @jason2678, for all your help! I learned a ton. Thank you, Samsung Experience Center , for making things so easy for regular folks (who just want to use their up-to-date phone) like myself!!

Thanks!! I will use the 19.8MB one then.
Just burned TWRP over the stock recovery.
Tomorrow I will go to Samsung Experience center over at Best buy. I heard that they bring samsung phones to the most recent available updates. We'll see how that will go. If this route will not lead anywhere, then I will burn NJ1 and NJ2 myself.
