How to update SGH-I747 to UCUFNE4_4.4.2
This is how I updated to 4.4.2
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.
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.
Or in a terminal emulator on your phone.
Step 1: Download and Backup
Download the files form all the links below and get those files ready
Odin, twrprecovery.tar and the 4.3.tar is for the PC
Copy the OTA.zip, MJB bootloader.zip and SuperSu.zip to your phones ext.sdcard
Backup your internal sdcard, 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://forum.xda-developers.com/show....php?t=1722686
and were going to use TWRP 188.8.131.52 just because I know it works. http://techerrata.com/file/twrp2/d2a....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 if using adb "adb reboot bootloader"
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 if using adb "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.
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
Make sure only Auto Reboot and Re-Partition are checked. Re-Partition will data reset and format the internal memory.
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.
When the phone reboots be ready to hold the button combo. If you let it completely boot you will probably have to repeat. Without root yet the ROM will install stock recovery upon boot.
Step 6: Flash OTA.
Reboot into TWRP 184.108.40.206 and flash this modified 4.4.2 OTA zip
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
If you don't root before you reboot out of recovery the stock recovery will be installed upon reboot. Flashing SuperSU will eliminate that.
Step 7: Root.
Before you reboot out of recovery flash SuperSU.
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.
If you havent rooted yet... when the phone reboots be ready to hold the button combo. If you let it completely boot you will probably have to repeat. Without root the ROM will install stock recovery upon boot.
