How to update 16 gig AT&T SGH-I747 to UCUFNE4_4.4.2

enewman17 · Jun 21, 2014

The development for the AT&T I747 has been discontinued by the developer. Thank you for your support.
WARNING: YOU WILL PROBABLY BRICK YOUR PHONE! The possibility is very real. Samsung made it difficult to update the firmware with the introduction of Knox.

This is a full firmware update!

I'm not the best at giving directions. I do expect a certain level of knowledge and skill on your end.
I did try my best to safeguard you from bricking your phone. The install scripts will fail with an error 7 if something is wrong.
More then likely if it fails... you are on very old firmware version. I suggest you double check your bootloader version and if it is older then the latest Odin update available on http://www.sammobile.com/devices/specs/SGH-I747/ Update to DLK first.

Or try updating the firmware incrementally. If your firmware is MJ2 or below, it is safe to flash any previous firmware without fear.
All available recovery flashable firmware that I have https://www.androidfilehost.com/?w=files&flid=10522

Firmware list: oldest to newest

747UCALEM
I747UCALG1
I747UCDLK3
I747UCDMG2
I747UCUEMJ2
============
Knox firmware
I747UCUEMJB
I747UCUFNE4
1747UCUFNJ1

Need a 16 gig AT&T I747 with a custom recovery.
usb debugging turned on.
adb and a rooted device.
proper drivers for phone installed on your pc
Knowledge of flashing and using Odin.

Checking the bootloader.
If your not sure what bootloader your on.

Code:

adb shell
getprop ro.bootloader
exit
exit <--- the second exit is to completely terminate the shell connection.

Or in a terminal emulator on your phone.

Code:

su
getprop ro.bootloader

1. In a custom recovery flash MJB bootloaders https://www.androidfilehost.com/?fid=23269279319197285
Reboot phone fully then reboot back into your custom recovery.

2. In a custom recovery flash the MJB to NE4 firmware update. https://www.androidfilehost.com/?fid=23501681358559161

3. Wipe and install UCUFNE4 in custom recovery.
Stock + Root: https://www.androidfilehost.com/?fid=24052804347765735
DeOdex + Root: https://www.androidfilehost.com/?fid=95916177934549032

4. (Optional) Flash the stock recovery in your custom recovery. https://www.androidfilehost.com/?fid=23681161096070493
While working with spagman72 on debricking devices we figured out no amount of ODIN will be as effective as a full wipe in the stock S3 recovery.
A wipe in the stock S3 recovery will also fix any sdcard encryption issues as well.
Now reboot back into the stock recovery and do a factory reset.

5. Use Odin and flash your preferred custom recovery again.

Hey man! Nice write up! Does this modded ota preserve root? Ive been trying to get one working all day here... http://xdaforums.com/showthread.php?p=53554046

For some reason it keeps failing to flash. My first attempt was in post #47 of that thread, but TWRP gave an error that the binary was incompatible (or something to that effect).

I changed the updater-binary but it still isnt working. Did you change yours? Just curious if you had any ideas. If yours preserves root though, I guess I don't need to worry about it anymore, but still wondering why it wouldnt work. If you have any thoughts I would love to hear them!
Thanks!

I didn't miss anything did I? [emoji3]
it's important that the directions are followed to a t.

I didn't replace the binary I only renamed the file and the extension from cfg to zip. then I just deleted the checks in the installer script. I didn't see anything that would get rid of root but with as easy as it is to obtain again it's really a moot issue.

Sorry, I might not have been completely clear. It wasn't yours that didn't flash, it was min in the thread I linked. Was just trying to understand why my own modded versions don't work.
The first attempt I only preserved root, and removed the recovery flash. That one was reported to error due to the binary.
Replaced it with a different binary and it seems to have other issues now. (I tried replacing the binary in one and another also removed all the file checks.)
You're right about rooting being easy enough. Just didn't think it'd be so problematic when I started with it. Anyway, no worries. Don't want to take your thread off track any more than I already have!

This is how I updated to 4.4.2

Need a device with a custom recovery.
usb debugging turned on.
adb and a rooted device.
proper drivers for phone installed on your pc
Knowledge of flashing and using odin.

Checking the bootloader.
If your not sure what bootloader your on.

Code:

adb shell su *grant super user permission on phone.* getprop ro.bootloader exit exit

Or in a terminal emulator on your phone.

Code:

su getprop ro.bootloader

Step 1: Backup
Backup your internal Sdcard.
Backup all personal info, apps, data, pictures, ect...
If your already on MJB bootloaders continue to step 4

Step 2: Custom recovery.
were going to go ahead and use Odin 3.0.7 http://xdaforums.com/showthread.php?t=1722686
and were going to use TWRP 2.6.3.1 just because I know it works. http://techerrata.com/file/twrp2/d2att/openrecovery-twrp-2.6.3.1-d2att.tar
Make sure phone is in download mode. With power off. Hold Volume down, Home, and Power till you see a warning screen. Then press up or adb reboot bootloader
Open Odin
Load the TWRP tar file in the pda slot and then press start and wait for phone to reboot.
Enter recovery by holding Volume up, Home and Power or adb reboot recovery

Step 3: Flash MJB bootloaders.
If your not already on the I747UCUEMJB bootloaders then you need to update them first.
Flash this in the custom recovery we just flashed.
http://www.androidfilehost.com/?fid=23269279319197285
Reboot your phone. Hopefully all is well and your on the new bootloaders. Check again by using the code above.

Step 4: Flash stock tar file.
Download 4.3 tar http://www.androidfilehost.com/?fid=23329332407590581
Unzip the file and you will find I747UCUEMJB_2024954_REV04_user_low_ship.tar.md5
Reboot your phone into download mode.
Open Odin 3.0.7
IMPORTANT! Make sure only Auto Reboot and Re-Partition are checked.
Check and load the tar.md5 file in the PDA slot. Wait a minute till its done verifying the md5
Start flash and wait till the phone reboots.
You can go through the set up once the phone boots up if you want and get it out of the way.

Step 5: Flash custom recovery.
Reboot phone into download mode and repeat step 2.

Step 6: Flash OTA.
Reboot into TWRP 2.6.3.1 and flash this modified 4.4.2 OTA zip
http://www.androidfilehost.com/?fid=23501681358549454

If you want root continue to step 7
At this point once you reboot you will have a phone that is now completely updated to TW 4.4.2

Step 7: Root.
Before you reboot out of recovery flash SuperSu.
http://download.chainfire.eu/450/SuperSU/UPDATE-SuperSU-v2.00.zip?retrieve_file=1

Step 8: Reboot.
Reboot your phone and verify the update.

Step 9: Flash custom recovery.
If you want a custom recovery...
Reboot phone into download mode and repeat step 2. Except this time use whatever recovery you prefer.
Or if you rooted you could use GooManager or ROM Manager to flash TWRP or CWM.

Will this wipe out internal SD or just overwrite?
Thanks.

Never mind my question. I followed steps 2 and 6 and was able to update my phone to 4.4.2. Thank you enewman17 and DocHoliday77 for all the help.

thanks.

After several unsuccessful tries at updating with the OTA, I used this routine and I have successfully updated to 4.4.2.

I had gone back to stock 4.3 using the routine in enewman's thread - http://xdaforums.com/showthread.php?t=2658486 I tried with the phone rooted and unrooted. With CWM recovery and stock recovery. The phone would find the OTA update when checking for update and it would download. When I tried to run the update it would get to 24% and then fail. This morning I found this guide and found success.

Thanks enewman for providing this guide.

Thank you so much for making this post! I ended up using this guide and it works very well.

Any chance we will get a Stock SGH-I747 AT&T 4.4.2 Odin *.tar file?

not sure if making one will be possible yet. missing a cache image that will be crucial to making a working tar.

if fails because it looks at the bootloader for the warranty bit info. when it sees it is tripped it stops. 24% is around that time in the script when it checks that after verifying the system integrity.

Can I go back to using AOSP ROMS after flashing this? I have one backed up but I don't wanna restore before knowing that its safe to do so

Step 2: Custom recovery.

In step 2, what boxes in Odin should/shouldn't be checked?

Should be fine. Worst that will happen is you'll have to go back on this when it hangs on boot or doesn't get signal/wifi.

Well I flashed the latest AICP nightly and it seems all is well.
I also flashed S3Rx but I did have to use the MJ2 kernel to get working WiFi.

Ok, thanks. I restored it without any issues whatsoever!

TylerMarshall256 · Jun 22, 2014

For some reason TWRP won't flash. This is what I get.
<ID:0/017> Added!!
<ID:0/017> Odin v.3 engine (ID:17)..
<ID:0/017> File analysis..
<ID:0/017> SetupConnection..
<ID:0/017> Complete(Write) operation failed.
<OSM> All threads completed. (succeed 0 / failed 1)
Alright what I had to do to fix that was reboot my computer and do a factory reset and I wiped the cashe too.
But anyways enewman17, You're the man! I'd like for you to take a bath with my two twin daughters, they could learn somethin from you!
