I was able to load CWM and load a new rom on an older build of the AT&T Galaxy S4, but since the update to 4.4.4./NJ4 I cannot get my second device to load CWM. I receive no errors when running Loki, I just cannot seem to get the recovery to boot - I endlessly receive the stock recovery loader.
Are there any tricks I may be missing?
Please post on Stupid Questions Thread - No question too stupid! so that one of the experts for your device may be of help.

So, I bought this at&t Galaxy S3 with leaked UCUEMJ2 (I assume) then I tried factory resetting it. It didn't boot up after the at&t logo. I tried flashing stock 4.1.1 which was risky but odin failed in it. I also tried reflashing UCUEMJ2 and Cyanogenmod, both stucked on the starting logo. Downloading mode shows something like Warranty bit:1 with red letters which is related to knox, I suppose. Please help, I just want my phone to work no matter which rom.

Okay, so apparently I screwed up greatly last night. I was trying to flash Android L 5.0.2 on my phone and after trying to flash it onto my device (using Safestrap) it did not work for some apparently reason (no md5) ,but before, I check summed the files if the codes matched and it did. So, I tried to restore and it failed and I accidentally pressed reboot and now I can't access Safestrap and stuck in a loop of the stock recovery mode.
It was running Kitkat 4.4.4
Safestrap 3.72
Phone: Rooted
Galaxy S4 SGH-i337
sorry for bad grammar, running sleepless atm

Thread closed. Thank you!
I have taken the first OTA update from VRUFNK1 to VRUFNK4 and have lost root. Not thinking I tried to flash OC1 and it failed probably due to disabled KNOX. am back to a working but non-rooted VRUFNK4
I realize that to flash to OC1 I will need to root first and probably do a full firmware flash from a PC to overwrite the Missing/disabled files.
My question is how can I go about restoring root and upgrading to OC1? Will I have to flash back to VRUFNK1 and root first? Please help as I am not so similar with the newer methods.

I'm out of Ideas, please help me.
Here is my info:
Samsung galaxy s3 sgh-i747m from kodoo Canada. I had installed cyanogenmod through their installer over a year ago. I have been using it with my rogers sim with no problems. Less than 2 weeks ago my screen randomly goes black. I try pulling the battery. The samsung logo appears but then back to black but I can hear everything is working. I Try and boot into recovery and everything is black. I boot into download mode and everything looks fine. I try reinstalling cyanogenmod and then Samsung stock through kies and smart switch and every stock kodoo file I can find .
There is one of two things that happen.
If I install a stock below 4.4.2 I get fail in Odin 3.07 and this on download mode:
Odin Mode
Product Name: SGH-I747M
Current Binary: Samsung Official
System Status: Official
Qualcomm secureboot: Enable
Warranty Bit: 1
Bootloader AP SWREV: 2
SW REV Check Fail : Fused 2 Binary 1
If I install a stock rom with 4.4.2 or install from Smart Switch
Everything proceeds perfectly but upon reset I see the samsung logo and then nothing just a black screen with the chime in the background. Still can't boot into recovery. I only see the recovery in blue in the upper left corner but then nothing.
I would greatly appreciate any help you can give me.

Thanks for the reply R_a_z_v_a_n.
The [HOW TO GUIDE] How To Unbrick AT&T I747 and I747M After 4.3 OTA states from the beggining: thus far this method will not work for any of your 4.4.2 ota bricks if you flashed the 4.4.2 modem on the mjb bootloader, the only way to fix those bricks is with a new emmc, motherboard or a new phone. Jtag won't save you this time the phone is now a glorious paperweight.
I believe I'm on 4.4.2. because those are the only roms I am able to successfully install but then of course the screen goes black. So if that is the case, does it mean my phone is done? just a paperweight as the article says?
I'm wondering if I should try anyways or is there a sure way to get my phone running from 4.4.2.?
Thanks for the help, look forward to your answer.

Hi again,
You'd be best served asking for help from the experts who own your device in the thread for Q&A I gave you link above, see bellow posted again:

Have a good day
I have a Verizon s3 running 4.4.2 with a locked boot loader so there's no way for me to get twrp. How else can I flash cyanogenmod?

Hello, and thank you for using XDA Assist!
With a locked bootloader, everything on your device is signed. Even if you managed a tar file for CM to flash with Odin, all you will end up with is a bricked device, because the signing won't match.
At any rate, for other options, I am connecting this thread to the forum your device experts can be found:

Quoting myself from another post:
I picked up a used i535 a few months ago as a device to mod and learn. I had no intentions of using it as my daily phone - I'm on AT&T with an i747. I found it was already on the NE1 bootloader and modem, I hadn't read enough before purchasing.
I was able to root it with TowelRoot. Following that I installed BusyBox and then installed SafeStrap Recovery for devices with the NE1 bootloader, see here.
From what I have seen there are three ROMs available to this device on NE1; stock NE1, SuperLiteROM, and Paul Pizz. This thread is a good resource for all but Paul Pizz, which is here. I after installing SafeStrap I flashed SuperLiteROM to the stock slot, it seems to avoid some issues when flashed here instead of a secondary slot. Since then I have installed XPosed framework and have several mods working with no issues.

Do not attempt to flash any custom roms especially CM. It's not a possibility and probably never will be on the VZW S3
