Bootloop after AT&T update - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

Hi all,
My i337 was rooted with Kingoroot, but my daughter went and updated it with an AT&T push that now causes it to bootloop. I can get it in to recovery, but any stock ROM that I try to install always fails. I'm sure that Lollipop was running before all this.
I've searched and read tons of threads, but nothing seems to work. Odin also fails to update.
Help!

DId you try recovery via SmartSwitch?

[Q] Att S4 Flashing Issue

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.

[Q] Cannot Update to Lolipop from NK2 kernel and cannot flash anything with Odin

Hello guys! I am having issues trying to update my Verizon S5 to Lolipop. I had been previously rooted and since uninstalled safestrap and SuperSU. When I tried to update to lolipop, it would fail and not update at all. I factory reset my phone to see if that work. It didn't. Then I had remembered that I had uninstalled a ton of bloatware previously and I might have accidentally uninstalled something that the phone needs to update. So I hooked up my phone to my computer and tried to use odin and install the factory NK2 firmware. I put my phone in download mode and it did start downloading but it didn't flash it at all and just rebooted. What should I do?
Thanks.

The firmware isn't what you should use by itself. Try flashing an nk2 stock tar, factory reset from recovery after flashing, and then try updating.

HELP NEEDED Can't update to Lollipop

Alright, I have a Virgin Mobile S4. I rooted it a year ago with towelroot and installed clockwork mod on it to install cyanogenmod. I tried it, didn't like it so I restored my backup of the stock rom using CWM.
Fast forward to now. I tried to update my S4 OTA for Lollipop, but it would give me an error. I figured it was because I had changed the recovery software. So I went and downloaded the virgin mobile lollipop stock rom from sammobile. ( I337MVLUGOC4_I337MOYAGOC4_VMC ).
I tried to flash it onto my S4 using Odin 3.09. To no avail, it always failed at the system4.img.ext or something. From there I tried to make it work by using 3.10. Still failed. I googled for a fix or workaround and found something about reinstalling clockwork mod. I also tried reinstalling the PIT file for I337M. It was still not working. So I tried to flash back to my stock backup.
1st time I flashed, I kept having program that didn't want to start errors. I wiped dalvik, I wiped cache, I factory reset. Still bugged. So as a last resort I restored the backup again after having done all this. It worked! But...
Well, I'm at a lost now, I can't update using OTA, I can't update with Odin, I can't update with Kies. Now what? Is there a way to go back to the stock recovery and let the OTA or Kies update go through unhindered?
The proper place to ask this is in the AT&T S4 Forum as there are more people with that device who are able to help you. This is the International S4 forum, and while we can help you in a general sense, there may be something device specific we'll miss.
With that out of the way, with the ROM you downloaded, there would be no OTA updates when you installed it as it is the most current ROM available. Since Odin should have worked but didn't, you likely need to use a different USB port, and make sure you're not using a hub. Changing the port can often fix issues with Odin.
As @Strephon Alkhalikoi says this is not the place for it.
But there is one thing I notice. You are flashing an I337M firmware. Are you sure that's your model and you don't have an I337 (without M.

[Q] Reflashed Stock w/ Odin, Still No Boot

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!

sm-g900f - trying to flash image via Odin

Hi all
I have a really weird problem with an S5 SM-G900F. I am trying to install to it via Odin a recovery and also root the phone.
I have used various versions of Odin.
The issue is that Odin works fine - we get the phone detected, we install the image, the green status appears and the phone reboots.
When the phone reboots, it doesn't do any installing - it just reboots back into the old rom.
I've Googled for ages and can't find out what the reason is for this problem.
Basically, Odin seems to work, but it's as if the image isn't booted, or written to the phone.
Not sure what else to do. I have tried running the same TWRP and root install to another S5 with no problems. Can someone help?
thanks in advance

When we install a custom recovery, and when we root a phone the ROM doesn't change.
I've found a post at last which helped the issue. It is ongoing as whenever I boot the phone normally, my custom recovery is overwritten.
