Well I followed the steps to the T and now it is stuck at the "Samsung Galaxy S III" screen for about 20 mins now. So what do I do now? I was on rooted 4.1.1 and everything went fine as I followed the steps and did the final boot after the wipe.

I understand, pull the battery again, leave out for a minute or so, push power button for ten seconds while battery out, then reinstall battery and reboot phone not recovery. Hope that helps

By the way which phone do you have? I747 or I747m. Make sure you used correct files.

I have the I747 and used files d2att_I747UCUEMJB_bootloader_modem_4.3 UCUEMJB_to_UCUFNE4_Firmware_update I747UCUFNE4_Stock_Rooted S3_stock_recovery

Update: Tried pulling out batter letting it sett for a min then holding the power button for several sec. After I put the batter in and let it boot it still stuck at the same screen.

Ok try this thread to see if it will help,

http://xdaforums.com/showthread.php?t=1831898&page=99

I am on 4.1.1 wanting to upgrade also, there may be a thread that can tell you how to flash with Odin and have those bootloader/radio packages. Wish I could help more but am at my limit I think. Hopefully someone will know the best way to proceed. Don't Odin anything until you find out for sure. My best to you.

If you can charge your phone do it

This may help but get someone who has been here a lot longer than me to confirm it.

I don't know for sure, please wait for someone better to answer, but you may be able to Odin the correct files to rescue your phone since download mode is still available

UPDATE: I found out how to get it into recovery. (Hold Home+Vol UP+Power once the blue text comes up in the corner let go of power and continue to hold the other 2) So whats going on now is I CAN get into Stock Recovery and Download Mode. So I went ahead and did a wipe and tryed to reboot to still end up at the same point. That being stuck on the flash screen. I left it for about 30 mins just to make sure it wasnt doing anything in the backround for the first boot and still at the GS3 logo screen.

Look at the post 2 above you, that link may help you out.

This might help you, but get another to confirm, I've never done this.

Those are factory, do some searching as there is rooted factory, but what I don't know is what bootloader you may be on now or if you can go back to 4.1.1 by that route. Then root and try upgrading again only this time don't use the two files to update, get each one and do them one at a time. I think you will need to use Odin but always confirm what I'm saying as I'm learning too.

ok I got it working. the bootloader updated fine. my issue was the rom didnt flash right so I re did that and rebooted. then got the hang later on the att logo this time. so I put the stock recovery back and did a wipe and factory reset then rebooted. now my issue is I can not send or recive SMS messages. I can do normal texts and I do have 4G connection so I dont know what the issue is. the APN matches up to what ATT says it should be for my phone.

    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

    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.

    Most of the bricks occurred because people ended up with a 4.4.2 modem on 4.3 firmware. Some also from using the ota, but that's happened with the normal unmodified one as well, so that's not enewman17's fault imo. If you follow the instructions EXACTLY, you should be fine. There is some risk, obviously, but blaming enewman17 in this case is not right.

    Sorry but you kinda lost me there. Please explain exactly what you flashed and how. Most boot hangs just need a factory reset, and you probably flashed an old modem causing your unknown baseband and imei.
    And please try to use punctuation. It makes things hard to read and correctly understand otherwise.

    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!
