Hi everyone,
I have an i337 that was updated to NB1. I used the NB1 to MK2 downgrade method to root and install safestrap on my phone. I`ve been able to successfully only install deadly venom`s rom on the stock rom slot so far.
I tried installing version 25 of Goldeneye 4.4.2 along with the Super SU file, but it never gets past the boot animation. It hangs on the glowing Samsung logo and glowing blue LED. I`ve even done a full Odin back to the MK2 rom then wiped and reinstalled it. It keeps hanging on the splash screen. I just reinstalled Deadly Venom earlier to get my phone running again and that worked without a hitch.
I read that V25 doesn`t need me to edit the updater script like V24, so I skipped that. I also made sure to install the NB1 kernels with Odin and the ATT NB1 Modules zip in SS before performing a full system boot. Was there something else that needed to be done before booting up?
Anyone`s help would be appreciated.

What ROM were you on, were you on NB1 at any point, did you flash the NB1 or MLD bootloaders? You should always be very descriptive in order to receive help quickly.
thanks for replying!!!

update***i tried the same steps but i replaced updater-script but this time i got stuck on samsung logo and the phone rebooted 2 times....
I was able to downgrade the phone to NB1 and root it with Towelroot, and used Safestrap in order to get recovery on the device.
After that, I booted into recovery and installed the GPE 5.0.1 ROM.: http://galaxys4root.com/t-mobile-galaxy-s4-roms/gpe-android-5-0-1-lollipop-rom-for-galaxy-s4/
Now the phone will not go past the S4 splash page, reboots and then goes into the stock recovery. Ive tried factory reset, clearing cache and removing the battery.
Any help is appreciated. I bought this phone for my fiance and am wanting to give it to her soon as a present.
Thank you so much in advance.
I think the problem is that you downgraded.

I couldnt install towelroot on the 4.4.4 version it came with since it said device wasnt supported.
I was following these instructions: http://www.droidviews.com/root-att-galaxy-s4-sgh-i337-android-4-4-4-kitkat-firmware-i337ucufnj4/
It states to downgrade, then root, then go back to the 4.4.4. I thought after the steps I took, I could go straight to a custom ROM.
Thanks
I used CF-Auto-Root to root my device. Since towelroot didn't work for me either.
Maybe the rom did not flash right. Try flashing again.
problem in installing lollipop rom india to samsung i9500
I have installed the newly released lollipop rom to my samsung i9500 through odin. it was successfully flashed but the phone cant restart, it stuck with samsung written on the screen and blue light on...what i should do???
I really need some help guys! So frustrated!
I have a Samsung Galaxy S4 i337 using SafeStrap 3.75. I followed the guide PERFECTLY just as it says, I have flashed all the files I need to in Odin and still no boot. My baseband is a NB1 and I have followed the guide many many times to get it to the new OC3. Can anyone please help me out? This is the third time I have tried flashing the rom and then flashing the kernel along with the stock partitions and no boot. I know it takes longer than normal for the first boot but I left my phone sit for over an hour with no luck. I can't access SafeStrap after I flash the OC3 also to even get my phone back to working somewhat. The first initial boot after flashing everything it shows the [SafeStrap : Disabled] and then i click continue and it goes black then says the same thing and it does that about 5 times or so then just a black screen for over an hour. I'm having no luck

Odin back any of the Kitkat kernels so you can get in to Safestrap, and make sure the stock partition file you're using is the correct .tar format. If you have a zip, that needs to be flashed in Safestrap along with the ROM and modules. Then you can ODIN the kernel and start again. If it is the correct .tar format, then make sure you let the phone flash the kernel, reboot, and wait for ODIN to say pass.

I've followed everything to the tee. I've re-read the directions millions of times but it's not booting. I have absolutely no idea why on this earth it won't. I've charged my phone to a 100% so it's not my battery.. I've used ODIN and flashed all the needed files until the green light comes on and says "passed". SafeStrap flashes on and off but then right after its done doing that.. NOTHING, no Samsung Boot Logo or noises just a stupid black screen. My phone feels hot after I leave it sit for awhile but never comes on from there. I feel like I'm the only one having this problem, everyone seems to be getting it to work successfully but I'm doing EVERYTHING just as should. I've flashed many many Roms before and I'm completely stumped on this one.
Hello all,
I am looking for some advice, on getting my AT&T Samsung Galaxy S4 working again. I will keep this as short as I can:
I originally had 4.3 rooted with the MK2 firmware, and used Odin to flash my phone to 4.4 NB1, using the ROM in the Guide to Stock/Updating/Rooting thread.
This worked fine, and I was able to boot and use the phone, but my root access was gone.
I tried Towelroot, Kingo, etc... to no success.
I then followed http://forum.xda-developers.com/showthread.php?t=2692825 thread to semi downgrade to MK2 and was able to obtain root again. I also installed Safestrap recovery.
At this point I could not successfully boot back into the phone, though I could access Safestrap.
I flashed the stock kernel for NB1 again, but still could not boot.
I then flashed the stock NB1 ROM again.
After this, the phone would show the android icon and a progress bar, then restart, reach the Samsung load screen, start the AT&T load screen and then boot loop.
Once I reached this point, I could no longer access recovery, only download mode.
In my attempts since then. I've found if I stop the phone from ever getting to the Samsung load screen after flashing the stock ROM, I can then access recovery. As soon as I let it boot, I cannot access recovery.
I've flashed the stock ROM multiple times at this point, gotten into recovery and wiped the devices then rebooted multiple times.
I just don't know what else I can do.
Does anyone have any ideas? A place to look? Any help appreciated!
OK, so I recently upgraded to a lollipop ROM on my locked bootloader ATT I337. To get into safestrap now, I have to use NC1 flasher to temporarily flash the NC1 kernel, and then boot into SS, then flash the OC3 kernel to get back. PITA, but it worked. So I tried restoring a backup, and when I rebooted it didn't work (black screen, kept getting FC's of every app, couldn't actually do anything). I rebooted 3 times, after which it seems to be working. Weird. However, if this happens again, how do I get back to safestrap so that I can wipe and reinstall the lollipop ROM? Can I just flash the NC1 kernel via Heimdall/ODIN? If so, which file is it? When I was looking, it seemed like I needed to start from scratch with a full KK flashable package, then upgrade, downgrade, etc, etc.

Yep, you can flash NC1 kernel in AP slot in ODIN. I'm not sure about Heimdall as I haven't used it.

Thanks, hopefully won't have to try it
Just as a bit of an update. I did another safestrap restore, and again ended up booting into the same situation, with black screen, mult FC, etc. Figured out that to exit this, boot into the system bootloader, and from there choose "reboot". For whatever reason, it then boots normally.
