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://xdaforums.com/galaxy-s3-att/...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://xdaforums.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.​

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?

Baseband: I747UCUFNJ1
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] mattsternc:
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. :confused:

Also, do we know what this update contains yet? Other than new bootloaders, removal of root, etc.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] enewman17:
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.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] OKAstro:
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?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] enewman17:
I have the nj1 system dump, I'll get it uploaded so anyone who updates can restore back to stock.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] OKAstro:
Thanks again my man.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Ark42:
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.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] enewman17:
Not sure if it still works but read the op you can Odin a custom recovery then flash super su.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Ark42:
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?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] wsyaeger:
Agreed! I'm the same boat as you.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] enewman17:
Tell you what, when I get home from work I will try cfauto root and see if it works.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] mwrobe1:
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!
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Long Island NOOBIE:
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!
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Ark42:
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.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] enewman17:
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.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Bob2014:
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.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] mattsternc:
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! :)
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] enewman17:
I'll get my stock rooted system dump up later so you can flash in TWRP or CWM.

Do you guys want it packaged with the stock recovery?

Downgrade cm12.1 to 4.4.2 ucufnj1

So I decide to go back to KitKat from CM12.1, I D/L the the 3 files on first page ucufnj1.img and the bootloader & modem and stock recovery. I wiped all the in CWM and flashed the system img first then bootloader & modem and then the stock recovery, it had a few problems on bootup so I did a hard reset and went back to recovery and rebooted from there, so everything went well after that, I went back to recovery and when it opened it say'sAndroid system recovery <3e> KOT49H.I747ucufne4,, ( my phone is on UCUFNJ1 ) in the menu has choice of apply update from ADB, apply update from external storage, wipe data/factory reset, wipe cache partition , apply update from cache, So I think but not sure if I apply the update it will TRY and downgrade my phone to ucufne4 which I think would Brick the phone . I dont know how to get rid of this update other than format the sd card and then flash a new philz, then do a backup and make that my recovery backup I do have copies of the org. I could put in the backup folder. Doe's this sound correct ? I wanted to see if anyone had run into this. 0
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] dawgdoc:
I think it is only the recovery that is based on NE4, the rest of what you flashed is NJ1. My understanding is that the stock recovery has not changed over the last several releases. [MENTION=2972841]enewman17[/MENTION] pulled the NE4 recovery to make it available for people needing stock recovery. This should cause you no issues.

Which update are you wanting to apply? To me it seems you are seeing the standard recovery menu present at all times in stock recovery, that is, present even when no updates are available.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] vtails:
First I'd like say thank you, I org. On UCUFNJ1, I went back to recovery after setting up on Kitkat and it asked to apply stock recovery of UCUFNE4 I've read that would Brick phone, before I did the wrong thing I'd ask. Everytime I go to recovery it ask to apply this recovery , I couldn't get past this. I'm thinking to flash Philz and see if that would stop recovery being installed so it doesn't try and downgrade my phone. I hope this would be correct.

[MENTION=2972841]enewman17[/MENTION]

Can I flash UCUENE4_Restore.zip even when I am on NJ1? I want to flash all my partition and reformat the Phone. My phone is getting heated very quickly and I suspect this was started after I have flashed the NJ1 bootloader zip.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] dawgdoc:
I wouldn't. enewman17's NE4-restore.zip includes stock recovery and the NE4 bootloader.

I thing the better flash would be the NJ1 restore at the bottom of the OP of this thread. It has system.img and boot.img. If you are wanting to go all the way and flash the stock recovery, enewman17 has it linked in another thread.

Mine gets hot really fast too.

Don't know if this is gunna help at all but here...
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] michaelcox:
Hey, before I realized my battery was bad, back when I thought it was a ROM issue, I reflashed everything that I knew how. I wiped/formatted the phone, I flashed the newest CM 12.1, new gapps, but none of that fixed it. So, I decided to update the bootloaders. It had been several months since I updated to MJB and I couldn't remember if I had done it or not. After I got a new battery that fixed my original issue, but I think I caused another one when I tried updating the bootloader and modem. This is what I did:

I tried to flash MJB: error 7

I figured that meant I had already done it (and I'm pretty sure I had)

I tried to flash NE4: error 7

I also thought that meant I had already done it (I'm pretty sure I had NOT)

I tried to flash NJ1: success

I figured everything would be ok now, but no matter what I do I can't get data on my phone. Is can't get 4g, 3g, edge, or anything. I there a way I can start back at MJB? I'm sure it's not a ROM issue because I have flashed several known working builds and none of them are making a difference. Does anyone have any ideas? When you flash bootloaders you also flash the modem drivers, right?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] mrrocketdog:
do not downgrade bootloader or modem , almost definitely will brick your phone. havent heard of any way to downgrade. people on the htcm8 are also having connection issues on cm12.1.

"all i can really do , is stay out of my own way and let the will of heaven be done"
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] wrenhal:
Are you sure you have upgraded both modern AND bootloader to NJ1?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] canodroid15:
If your baseband in settings/about phone reads I747UCUFNJ1 Flash this in recovery: https://www.androidfilehost.com/?fid=95832962473396872

This is the bootloader & modem combo zip. Your bootloader & modem MUST match. If this doesn't fix the issue, then you may have a problem with your efs partition... Also you can't skip versions so if you started on MJB you should have flashed the NE4 combo, then NJ1 combo. However you can't go backwards if your phone reports NE4 or NJ1, if you try you'll most likely brick
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] michaelcox:
I was under the impression that they were all combos. I flashed the files from http://xdaforums.com/showthread.php?t=2789917 to get to MJB and NE4. I got errors for both, but I think I had already flashed MJB a couples months ago. The link you shared appears to be the same file that is in the original post of this thread. That's also what I flashed. I don't know if NE4 was ever flashed successfully, but I do know that NJ1 did.

So, now that I have flashed NJ1, whether in the correct order or not, and nothing works, what do I do? I can't go backwards, so am I stuck with a permanently broken phone? Is there no way to clear/wipe the bootloader or modem and start over?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] canodroid15:
No you're not stuck, gimme a little bit & I'll help you fix the issue. Do you use hangouts? I'll be home in a few hours & I'm pretty sure I can get you going again if you wish
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] michaelcox:
Wow. That is extremely nice of you and I really appreciate it. I'm not sure what the problem is anymore. I played around with the APNs and I'm now able to get H+, but still no 4g. It seems like a ROM issue that only I am having.

I'm very impressed with your willingness to help. I don't think this is the same problem I thought it was. Do you?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] canodroid15:
No problem man, I don't mind helping anyone provided they've searched & tried several times to fix it themselves b4 asking which you've done.:thumbup: If you're getting any type of signal at all then its probably not BL & MDM related, there's a chance it still could be but its likely something else. The reason I mentioned hangouts is its just sooo much easier to communicate. Let me know if you get it & if not just shoot me a PM & I'll get with you on hangouts :cool:
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] dawgdoc:
[MENTION=6179543]michaelcox[/MENTION], if the issue is still unresolved; before doing anything else I would recommend verifying both the modem and bootloader versions. You could either run Phone Info -- Samsung from the Playstore by vndnguyen or using the command line in Terminal Emulator. Those commands would be:

getprop ro.bootloader
getprop | grep version.baseband

If both your bootloader and modem are at the same version there are a couple of things you could do. You could reflash the current matched bootloader and modem. If that doesn't do it, I've seen reports that deleting all but one APN option has fixed connection issues in some of the LP roms. (This could be something you have already done, the playing around with APNs that you mentioned.)
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] antb7:
Hi!

So I read through just about everything, and I am pretty sure I got it, but wanted to be sure. I always get nervous when flashing this stuff.

I have the i747 on NE4 (according to the about phone) running cm11. I wanted to go to cm12, and don't really care about stock. My recovery is the latest twrp.

Do I just put the modem and bootloader flash on the bottom of the first post on my SD card and flash, then flash the cm12 and it should be good?

I guess my biggest question is where to flash from, is the file ok on the sd card (like a normal rom) or should I put it on the system memory?

Sorry for the noobish questions, but I know just enough to be dangerous :)

Thanks in advance for any advice offered!
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] mrrocketdog:
yup. just put what you want to flash on sdcard and do a full wipe and flash away. CM12 should be fine on NE4 if you dont want to upgrade. and you can always flash nj1 after if it isnt.

JUST REMEMBER ...... alwaysalways make a backup (from twrp) before flashing anything.

AND .... since youre already on NE4 you can NEVER downgrade bootloader/modem or risk ; 99.9999% , brickage.

good luck and happy flashing.

p.s. make sure you flash for your device/carrier. :D

im running srx3.0 and am updated to ne4 bootloader and modem. could I use the flashable nj1 modem and bootloader zip to update the bootloader and modem only?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] canodroid15:
Yes, you can use the combo zip to update just the BL & MDM. I actually went from MJB incrementally to NE4, then NJ1 & finally the latest NJ2. My LTE has been solid since updating to NJ2. Less call drops with NJ2 than NJ1. I'm sure you know, but incase you dont I'll say it. You can update BL & MDM, but you can't downgrade. You can't skip versions either.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] athlonxp2300:
thanks. that is what I was planning on doing. I'm running tmo version of s3rx v3 on my I747. I've tried the s3rx v4 a little but haven't switched. I was thinking to update bl & mdm only just like you said. ne4 to nj1 to nj2. but knowing that I can't go back I didn't want to be forced to a new rom because of the bootloader or modem . especially if enewman doesn't rebase s3rxv4 on nj2. I love his work!
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] EAK128:
I am kinda out of ideas at this point, the S3 I747 I got originally had 4.4.2 stock with NE4 bootloader, rooted and with TWRP as recovery, I made a backup and flashed SlimLP on it to try it out, but now I want to go back to my 4.4.2 backup and it gets stuck at the att logo, so after couple of factory resets I gave up and tried the restore zip in the OP and the same thing happens again, does anyone have any ideas I could try, I want to go back to stock 4.4.2.

Alright after taking out the battery and going back into recovery I saw that twrp was gone and the stock recovery was there, so I did factory reset in there and rebooted and it booted up, so I'm back in business, stock 4.4.2 rooted.

Thanks for all the great resources guys.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] unimatrix725:
I am confused after reading a few threads. I saw a few statements saying that the NE & NJ Bootloaders are unlocked.

Can someone break this bootloader down a bit? I am far from a n00b. My understanding was : Installing 4.3 last release or above locked bootloader and would cause a brick if downgrading. I personally consider NOX Spyware... I noticed that the KitKat and above apparently introduced the requirement of matching modems.

I am getting ready in the next few months to get a newer phone. I wanted to have the latest CM12.1 based rom on it, in case I need it again. I am having issues with 12 & 12.1,so I began researching what was different. I thought my baseband issue was from the efs partition format changing to ext4? I read somewhere to re symlink the fw files, which didn't help. I had odd issues in cm11 with every other rim having sound&data, then not having these. I want to start fresh again. I am currently at mjb modem&boot.

TLDR:

Could someone please clarify specifically which bootloaders are unlocked and should I use the guide mjb to NE. I feel like its reasonable, but am confused with my newfound info. I have read that I must apply each incremental update until on NEx, seems tedious! I may be thinking about the Verizon model, but thought knox locked all models up tight. AT&T only recently become an option, but has less coverage in the area.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] mrrocketdog:
my best guess is : yes , having the mjb modem will cause issues with data and possibly wifi with newer ROMs. my best understanding is no bootloaders are locked (went all the way to mj1 with no issues). and yes flash incrementally and reboot inbetween. and again yes ; bootloaders/modems have to match. you will 99.99999% brick if downgrade after NE4. dont have a link but enewman has a thread with flasable bootloader/modem combos , so you can flash both at once. good luck. :thumbup:
