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!

Phone: Samsung Galaxy S4 ATT I337UCUAMDL
Model Number in settings on 4.4 ROM = GT-I9505G
As the title says, I installed dandroid's newest 4.4 ROM from WICKED v5 4.2.2 and lost root. So I attempted to update my CWM Recovery from Odus 1x to the newest using Odin which failed do to write protected I suppose all though others says that doesnt effect their installs.
Where I'm at:
Cannot boot into recovery, says booting recovery the just reboots and enters Dandroid's ROM w/o root.
I'm now lost and have been reading the forums for hours. Currently downloading STOCK Samsung firmware for my device I337UCUAMDL_I337ATTAMDL_ATT.zip
CASUAL failed.
What do I need to do to get back to WORKING custom recovery w/ rooted dandriod 4.4 kitkat rom. Should I use Odin and flash stock rom then motochopper to root and try to reinstall working CWM recovery?
Please advise best course of action. My phone had been working properly with every ROM I tried before update to 4.4 ROM and attempted CWM recovery update (thinking that would fix my root issue). Thanks all!
If you have a nandroid, and I hope you do, just restore that in your custom recovery. If you don't, then you're going to have to return to stock with odin
Tried motochopper on the phone as it sits and it fails as well.
I have a stock backup but the problem is I no longer have access to any recovery. Guess I'm just gonna have to flash the stock firmware with Odin when its finished downloading and start over.
Just finished Odin flash back to samsung factory firmware. Phone stuck at att world logo on bootup, still can't access recovery. Any ideas?

If you flashed Odin successfully you can get into recovery.
Finally got into recovery it rebooted 3 times but just holding the req. buttons finally got me in.
Back on factory firmware and rooted w/ cwm recovery all back in place properly worrking.
I would like to use the Dandroid 4.4 ROM with this device. When I install am I going to lose root again and if so, how I do I get it back on this device since the model in the settings is going to change from I337 to I9505G after installing this ROM?
Figured it all out last night, re-flashed Dandroid's latest ROM which still caused me to loose root, then flashed SuperSU 1.51 instead of 1.80 and regained root. All is right in the world now.

Hey, if you dont mind me asking where did you get the 1.51 zip to flash? I'm having a similar issues with same ROM where i lost root but have recovery access.
Thanks
Update: Found the file. Flashed it. Root is back. Have you let market update it automatically? If so did you lose root afterwords?
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???
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.
have rooted s5 on 4.4.4 nk2. Have been trying to install custom roms via safestrap. Apparently i am missing a step. I wipe data, try to install twi5ted Lollipop on custom rom slot....blank screen for over 30 min after reboot, phone gets real hot, take battery out. Try to install on stock rom slot, reboot then get stuck in boot loop and keeps booting into system recovery. I then saw through my hours of searching to format instead of wipe....so i format then try to install, get stuck again, take battery out, get back to safestrap dash now when i try to wipe/format/or even restore my backup it says unable to mount system. When i click reboot system it says no OS installed. After reboot, my custom slot gets erased.
I was about to try an odin flash back to stock but some how was able to get my phone back to a system restore. Why can i not get anything installed? Do i have to have odin to do a custom rom install?????? i know every rom is different but wtf. I have seen multiple videos and threads of people flashing zip via safestrap and rebooting into new rom without flashing kernals via odin or safestrap after rom install.
Also...my phone will not let me download zip files (ex. cm12.1) says unable to create download folder....how close to F'in my phone up am i? I have successfully rooted all phones in the past...s5 is giving me hell!
I just tried installing rom after format, then flash nk2 kernel from odin, still gives boot loop....ive tried everything i have found..never this much problem with custom rom..
When you try to install twisted it needs lollipop firmware which is flashed on odin, and based on your statement it says you're on NK2, a kitkat firmware. Try flashing a stock ncg tar and rerouting, downloading apps, etc. on the phone to see if that works. Also, I noticed you mentioned a cm 12.1 zip not downloading which, while unrelated to your current problem, will cause a bootloop when flashed due to the locked bootloader on the S5, so it isn't a smart idea to even attempt an install.

thanks, i will try fresh from start ncg. so you have to be on the current kernel that you are flashing a rom for, whether its CM, Twi5ted, Alliance...etc i need to be on rooted 5.0 kernel then flash rom via safestrap?
i was having problems downloading from internet on phone, not downloading rom if thats what you thought i meant. I just tried installing zip for CM 12 via safestrap and got same issue. Phone reboots, goes to black screen and eventually heats up like crazy. .... I just noticed, after my restore ...again... it says safestrap disabled in red on the boot screen, why is that? it says installed and tried reinstalling.
FIXED
So i flashed ncg from odin on the messed up phone and got messed up worse. Ended up getting stuck on first boot image of samsung android s5 boot screen. Finally found original stock firmare file and used odin to complete install stock os and got rid of root. Now back to normal... luckily i figured it out my self! thanks to the 100's who viewed and didnt help and thanks to mrjiggywiggy for giving me some input to help out!
Not a proud moment here... I have been running a rooted SM-N900V for a while on 4.4.2. Wednesday I made a backup of the rooted 4.4.2 using safestrap to the external SD card. I then wiped the ROM and tried loading JasmineROM 6.1. After flashing, the phone rebooted to the Verizon unauthorized software screen. At that point I could not boot into recovery. Using ODIN, I was able to load flashN900VVRUEOF1_PartialFirmware.tar.md5.7z which allowed me to boot into recovery. However, for three days, I have been stuck there and cannot get any further. I have tried flashing stock ROMs in Odin but all I get is the AUTH fail and Write fail. Is there a way out or is the phone toast? Is there a way to load the recovery I made in safestrap?
Any help is greatly appreciated even if I have to mail the phone out...
Thanks!
