ATT S5 Active (SM-G870A) bootloop issue... - Galaxy S 5 Q&A, Help & Troubleshooting

The phone hasn't been rooted or otherwise tinkered with and is currently on android 5.0,.
Recently the phone has started boot-looping (never gets past the black S5-Active screen), though it strangely works fine while on the charger. This seems to have started when it tried to download an ota update from att a few days ago and the install failed.
I've tried using odin to flash it back to stock and start over, but odin seems to always fail, i can boot into stock recovery just fine and it will stay there once you get there.
Any help would be greatly appreciated.
Thanks in advance.

Tried clearing the caches from recovery?

yes, have cleared caches, and wiped data/Factory reset. neither seemed to have any effect.

[Q] SGH-I337M Stuck on Boot Screen

I really hope someone here can help me. I'm running an SGH-1337M (Rogers). I rooted the device a number of months ago with Motochopper and installed Foxhound ROM GT-i9505 (which every guide says works with the SGH-1337M). I've been running this rom for quite a while without issues. Yesterday I I installed Cyanogenmod (cm-10.2-20131102-SNAPSHOT-M1-jfltecan) which worked, until I rebooted the device. When I reboot the phone gets stuck on the Samsung Galaxy S4 boot logo. I've booted into TWRP and tried to reinstall the Foxhound rom which was working but end up with the same results. I've used Kies Firmware upgrade to try and set everything back to default without sucess. Using Odin I tried to reinstall a factory image of my phone, which is sucessfull except nothing changes.
Currently, if using TWRP I do a full wipe of my phone and then install Cyanogenmod it'll work, so long as I don't reboot. If I reboot I need to do a full wipe, reinstall the rom and start all over.
I'm at a complete loss here. I've spent the last 5 hours looking for a solution to this problem without success. Any help is greatly appriciated.
Thanks

After you did odin, you must do a factory reset. This should clear up the problem. And, are you using the correct kernel for cyan?

[Q] Is my G2 dead?

Ive been running CM12 for a long time, but today I noticed I had a few missed calls and my phone hadnt rung. I rebooted the phone and it went into a boot loop. I cleared cache, but still bootlooping, dirty flashed the latest nightlie and then a full wipe - all of which resulted in the boot loop.
I restored my phone using the TOT method, but it would get to the setting up google account/wifi etc and reboot.
I used KDZ to install 30b lollipop ROM this seemed ok until reboot and then it would factory reset, optimise apps every time and be back to the setup screen.
I managed to install KK using KDZ and this seems more stable so used IOROOT and Autorec. I then flashed CM12 and GAPPS again, but it started to boot loop again.
I hadnt done anything to my phone prior to the problems - ie. no new ROMs, kernels or even apps.
Any suggestions or does it sound like something more physically wrong?
I have managed to get Cloudy G2 2.2 working without any problems except it isn't recognising my SIM. Does anyone have any thoughts or is this a dead phone?

Help - G935A stuck on AT&T Logo - 3 vibrtations

For a week my G935A worked fine... direct out of the box I flashed ENG Kernel and Rooted, then installed apps and configured - no issues.
Today it was working then it hung on wake.. I tried to reboot and now it gets stuck at the AT&T logo and vibrates 3 times - over and over
I can get to Odin and Recovery screens easily so I tried to flash the ENG Kernel again & deleting Cache Partition few times - didnt fix it.
Also tried booting into Safe Mode - it never gets there, stays at AT&T logo.
When I go into the Recovery menu, I see at the bottom, in red... "dm-verity verification failed"
Anyone know how I can recover from this without Factory Reset? It took 6 hours to reinstall and config all my apps - really want to avoid that.
thx for the help!
as far as I know there is no way to fix and save your stuff. I had the same problem with G930A and even doing a factory reset would only allow my phone to boot but then I get apps crashing and then a reboot puts you back at ATT logo and the vibrates. Best to ditch the whole engboot and go back to stock until a more stable rooting method comes out.
Some searches shows posts that say using Odin to flash HOME_CSC without having to wipe and everything survive
... Where can I get HOME_CSC? I dl'd stock rom and dont see it in there.
thx!
Same here this morning on my 930A w/ PK1....went to watch a youtube vid and everything google related began crashing.
Only been on engboot for a couple days but did flash the v15 debloat last night. hmmmm.
Any luck with the files or procedure LivinOne?
Update: Flashed the PK1 CSC and got into recovery.
Wiped cache and reboot, same failure mode....sad face.
Flashed CSC again, into recovery, factory reset, wiped cache.
Back to setting my "new" device up.
Dec 30 update: Same crash, SEMI same problem.
I get the single vibration followed by the 3 vibrations after I put my pin in from a restart.
Same symptoms prior, all background activities began crashing.
Running all PK1 files from QRhinehardt post.
Any thoughts?
I ended up wiping and flashing the T-Mobile firmware and using the ENG bootloader (but not rooted yet). It is WAY faster than the AT&T was. I've only had issues with Wifi Calling (it doesnt seem to work most of the time)

Hi, did you first flash with eng bootloader and then tmobile rom? I miss this step...I appreciate your help please
Single vibration followed by the 3 vibrations
Hi, were you able to fix the problem? I'm also getting the single vibration followed by the 3 vibrations.
Do you know why is this occurring? I performed a wipe cache and factory reset but still nothing.

SM-G935P (Sprint) Root gone bad. Need help restoring to Stock Android.

I recently rooted my S7 Edge using Odin and it worked for about a day. It was slower than my stock Android and I was tinkering with it, but it eventually froze and when it rebooted it booted into Recovery Boot. Every time it reboots it tries to install a System Update which I presume fails and goes back into the recovery boot. I tried running the graphical test but it just says error and tries to install an update and the cycle repeats. I have ultimately decided I just need to reinstall the stock firmware, and have wiped the Cache and Data using the recovery boot options. However, when I plug it into my laptop it does not recognize my phone at all now. This causes quite the issue as I can't flash anything if it doesn't recognize my phone. I need help as to how I make it recognize my phone again and any other steps I might be missing to reinstall stock firmware.
Just odin Full stock Sprint firmware... I had that happen once, and it took care of it.. I'm re-rooted for about a month and it works flawless.

Rooted phone bootlooping, clearing cache and factory reset not helping whatsoever.

My phone is doing this weird bootloop where it loops 3-4 times, boots up, and starts looping again after 30 or so seconds. So I rooted my phone with Odin and CF Auto Root, and it worked fine. I tinkered around a bit, tried to get my games on my sd card with gl to sd and FolderMount [Root]. I had no success, so I uninstalled them. Everything was fine until then. When I tried to open one of my games(one I didn't tinker around with), I got a pop-up saying something like "reboot to recieve benefits", my phone resetted and started bootlooping. I have no idea what caused it. Everything was working fine until that moment. I've wiped cache, factory resetted(when it boots, I get an error saying the UI is disabled and it reboots). I can't afford Reiboot, and i'm going to try to flash stock firmware/ROM with Odin, but I don't know if it will help.
