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/gala...2#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/gala...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/d2a....1.0-d2att.tar
SuperSU http://download.chainfire.eu/589/Sup...etrieve_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.



Flashable Rooted NJ1 system.img and boot.img

Flashable NJ1 Bootloaders and modem. *Must be on NE4 bootloaders prior to flashing.*

Question
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?

I have the nj1 system dump, I'll get it uploaded so anyone who updates can restore back to stock.

Info 2
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?
