July OTA Update Bricked my Phone -- AT&T refusing to replace. Help!

Completely untouched phone from AT&T. Have never rooted or modded this phone in any way.
The update that came out this month was sending my phone into random boot loops. Would have to take the battery out and after a few tries it would stay on for a while then at some point in the day randomly go back to the boot loop.
I backed everything up through Kies then went into the recovery menu and attempted a factory reset. This sent the phone into a permanent boot loop -- would never turn on or off. Sammy logo flashes and it would reboot. Only way to get it to stop is to take the battery out.
Attempted to go back to 4.4 through Odin since those where the only firmware files I was able to find. Updated failed. Now, when I turn it on and I just get "Firmware upgrade encountered an issue. Please select recovery mode in kies and try again."
Kies will not recognize phone. Cannot update firmare from internal storage because I can't even get into recovery menu -- it just goes right back to the same screen.
Called AT&T and the rep told me he would replace the phone through warranty even though I was past my warranty date. He told me this update has messed up a lot of phones and this is not the first he's of it. Then his manager gets on to approve the warranty replacement and she refuses to honor his promise -- tells me they won't do it, I'm SOL, and I can use my upgrade. Maddening!
Please help -- I need a working phone!

Most attempts to downgrade only flash the kernel so here is the OF2 kernel which should get your phone to boot again. Flash with Odin:
G900A_OF2_Stock_Kernel
Once your phone boots place the G900A_OC4_tF2_OTA.zip onto your extsd card and flash as update from stock recovery. That should get you back to 100% factory stock. Do a factory reset after flashing and if it still does not work I suspect a hardware problem.

Thank you for the reply!!
Kernal flash worked and I was super excited to get back to recovery menu -- way more progress than I've had up until now!
Unfortunately when it went to reset after installing the update from external storage, it went straight back into the Sammy logo boot loop

Is there physical damage on the phone, thus why att didn't do the warranty?

Take it to Best Buy or an ATT Store and have them reflash it before you toss it away. Good luck

No idea what just happened. I've been messing around throwing the kernel you recommended at it as well as the stock partitions. Kept getting back to boot loop but at one point it stuck out, said it was upgrading, optimizing apps, and now it's running. So weird.
I'm way too scared to do the factory reset at this point, though.
Thank you again for your help, I really appreciate it!
Edit: Unplugged the USB cable and it immediately shut off and went back into boot loop. Wow.

this sounds like a hardware problem.. i sent my phone to Samsung and they actually repaired it, it was the pba board, i had the same problem.. i flashed everything it needed to recover from a bootloop. and sometimes it would become non responsive. go to best buy and see what they tell you.
Sent from my UNROOTED SAMSUNG-SM-G900A on OF2

Update:
Thanks to everyone for their replies. I was able to get the phone to boot thanks to everyone's help. Did this by flashing kernel then partitions which would allow the phone to boot.
I finally figured out that the phone would only boot if plugged directly into a power source. As soon as I disconnected the power cable, it would send it right back into the boot loop. I ran some battery "repair" and "calibration" tools but these did not fix the issue. Whenever I would run a battery drain tool, the stress on the battery would cause the phone to shut down.
All of this led me to believe it was an issue with the battery. I held my wife's S4 battery to the contacts on the S5, and it works just fine, even disconnected, and even with the stress test on the battery.
SO -- I'm going to buy a new battery and see if this fixes my problems. I think I just had the perfect storm of battery issues coupled with firmware problems.
I'm pretty sure I know what caused the battery to go haywire. I work in a max security prison and have to leave my phone in the car all day. Outside temperatures regularly hit 105F+ during the summer, so who knows how hot it's getting in the car. Obviously I always leave the phone turned off, but I suspect the high temperatures caused the damage.
Going to try to find a new battery today. Will keep everyone posted! Thank you again for all of the replies.

I had the same issue and would just like to thank you for the files! They helped me unbrick my phone! Much appreciated.

Stuck on boot loop, cant flash firmware, have exhausted all options

Phone has been in the ****ter for the past day. Stuck on boot loop. I tried flashing the most recent stock firmware. It would not do it and kept throwing auth failed signs at me. I tried other stock firmwares for tmobile with no sucess. I Tried throwing them on my sdcard and installing through there in TWRP, but I keep getting md5 auth failures. I have wiped, factory reset, and cleaned house many times. Nothing works. Im at my wits end. Someone please help

I'm a guest to this forum..but same thing happened to me about 5 days ago. Last thing I remember seeing is the 5. update trying to take place and I was just about OUT of Internal memory (with NO microSD card). Phone just kept rebooting. I was able to do a Factory Wipe (Both in the OS and in the Recovery Mode)....Neither worked even though they appeared to be successful. Phone just came back with ALL of my data still intact. The other weird thing...I had about 60 seconds before phone decided to reboot each time. During those 60 seconds I was able to delete files, pictures, etc. to save space. As soon as the phone rebooted those same files were back! Very frustrating. Still having the issue.

im not sure what states either of you guys are in, but you can look on craigslist for people that do flashing. you make need to do a odin rebuild because the partitions are ****ed.
you can repair it yourself but with pure caution.

Have you tried flashing in download mode with your computer through ODIN? If twrp doesn't work, that's what I go to next.
You could also try flashing the firmware without the MD5 file and I believe twrp will skip the check. (not positive on this one)

Figured it out on my own. Flashed CF autoroot. Then flashed 5.1.1 which is the most up to date firmware. Im not sure if the issue was because I was doing 5.1.0 and didnt realize that was the most UTD version, or if CF to 5.1.1 was the trigger. Either way, it worked.

Soft brick help. Twrp installed Android won't boot custom rom

I didn't want to make a new thread. But I've searched high and low.. And nothing has been answered. So here's my story. I have a note 4 sm-n910T. When I rooted the phone everything was fine and good. I then decided to give it to a family member. I flashed it back to stock.. All was fine for a while but it started acting up. Like randomly turning off and not responding to a charge or any commands to turn on into other modes... I had flashed stock again. All was good.. Till now. My madre and received a Ota update, downloaded and installed the update. When I pressed ok to reboot new update. The phone never came back on. So I went through all the fun stuff. I tried kies.. Kies days unsupported device connected.. There is however talk between the two because it's pushed errors onto my phone as well as has tried to download the stock rom. But every which way I've tried it fails. Next. I decided to go for custom roms... And flash cf-chainfire auto root. Then twrp.. Then install supersu.. Then a rom from twrp. Now here's where it gets interesting. Nothing would pass odin if I had auto-reboot and f.reset time checked.. Any and all roms.. Files..etc would only pass with auto reboot checked and f. Reset time unchecked. At first everything seemed ok.. I was able to actually get cm 12.1 installed as well as gapps. But only the one time.. Which you'd think was good enough. But here's what has happened and what I can't seem to fix. The phone yesterday after having everything installed and sitting at home untouched.. I came home clicked the home button.. And it came on.. I scrolled a few pages.. Thought.. OK cool.. Let's get madres Sim card in and call it a night.. When I turned the phone over.. (didn't even take our the battery) tried to see if I could fit the sim in.. Which didn't.. I then turned the phone back around just Cuz I wanted to make sure it was awake.. The screen was black.. I figured it was in sleep mode.. So I hit the home button.. No response.. I hit the power button.. No response. .. The phone had turned itself off.. And when I tried to turn it on it wouldn't. Now mind you the phone has these weird phases where when I try to install or flash a rom and it fails.. And I'm forced to remote battery.. A good portion of the time it won't turn back on.. Sometimes it can be instant.. Others.. A few mins.. Sometimes even longer for it to respond.. Right now I have been accessing twrp.. Wiping all data.. Davik...cache.. System.. One by one.. Then installing a rom.. I go for a reboot.. And I get a black screen. I need help.. I'm running out of ideas and basically just fishing random idea attempts. I'm no scared to brick it.. So all ideas are welcome. Plz. Thank you.

Also how important is f. Reset time? I don't totally understand it. Next.. What about having the roms and files I flash on internal memory instead of sd. I'm not sure if I can access the Internal storage. But if I can does that help. Also I cannot access Android at all.. I can either access download mode or recovery. I have been using an external battery charger to charge my battery as well. Due to it doesn't read the charge... But! It did read a charge just fine when I had cm 12.1 working.

I would suggest:
1) In twrp wipe system, both the cache's and also data
2) use ODIN to install the stock Note 4 ROM
see -> http://forum.xda-developers.com/not...uide-odin-to-stock-unrooted-firmware-t2957156
3) When it is finished unplug the usb from your computer as the phone is rebooting
NOTE you might want to uncheck Reactivation Lock in Settings - Security first

Answering question one.. I do that already. I wipe everything one by one except sd... Answering question two. I have tried that already and odin fails.. However I'm sure if I tried to flash the rom and didn't check f. Reset time it might work. But as for flash stock.. I have tried several times.. I can't say one error or another I'd a cause because I get a different one each time.. What is the purpose of f. Reset time in Odin? I've searched it and to me the explanation didn't make since.

Reactivation is unlocked. Also I wouldn't be able to change any setting in the phone.. As the phone does not boot into Android. I was just lucky enough to have usb debugging active before this all happened

I am not sure what that is for
But every time I have done a flash it works if you use the steps I had there. (Not really questions)
Sorry I do not have anymore ideas.

Are you booting your phone into download mode before you use ODIN?
(I know it's proly a dumb question but just in case)

Yes I am in download mode when using odin.

Just now I did another full wipe and wipe of cache, davik, system, internal memory and had a successful install of cm12. 1 with gapps.. Everything installed.. Clicked reboot and the phone never came back on. I will try your idea next. I have not tried an idea where I use twrp to wipe everything and reboot into download then do stock rom via odin. If the phone does boot into download from twrp recovery I will try this one time with auto reboot and f. Reset time checked.. If it fails I will try it again with f. Reset time unchecked. I am currently not by my laptop to try this so it will have to be much later in the day.

To boot into download mode: Power off Note 4, hit all 3 of these at the same time until it wakes and vibrates - Power Button, Home Button and Volume Down

I know how to do that lol. I know I'm a junior member. But I'm somewhat intermediate. So cm12. 1 has booted.. However it didn't from a reboot of a flash.. I just took a while shot.. And powered the phone on.. And it booted.. I'm pretty sure in going to run into the problem again.

OK - Well you never know!
I am only a senior member 'cause I am older than Dirt!

Lol. I'm oldish. And trust me this lucky catch I got.. Is temporarily. There is still boot issues. I fear when the phone goes off or is turned off that it won't come on. I do not have a sim card in the phone at the moment which means I can download helpful apps. Like supersu. .. But so far I was able to check settings and get what I can prepared. Also if like to keep this thread open as a log or research tool.

Alright so I like the rom sit most the day.. With minimal to no use.. Most of the day it was fine.. At one point I took a picture and it did as it should.. I cleared all open tabs.. Took another picture and I got a error saying camera wasn't connected.. Finally the phone froze up and rebooted.. And the Camera worked.. Gave it another rest.. Came back to it checked the camera and it was fine.. I put it away for like 10mins then decided to check recording. When I did the phone was not responding to turning back on from sleep mode. Now for as long as I can remember even before this initial issue started.. I was having thr same problems with the phone not coming back on from when in sleep mode.. I dunno what the cause is or hoe to approach it to fix it.

First attempt was to put it to a charger... Registered no charge.. So I removed the battery.. Gave it a few mins.. Pushed down power button.. No response. Something is off with the boot menu.. Like the boot img. File

And finally it's back on.. Normal boot.. I didn't boot from download menu or recovery.. But in all honesty I'm 100% sure this will just happen again.. It seems to happen when I put the phone in the charger.. Then take it out and play with it.. For now in going to let it sit till the battery is in caution. Then charge it. I still have not added the Sim and loaded apps.. I feel that will be a overload of cpu and will most certainly freeze up and crash the phone

Ok, so up to date now.. Here's what's going on. The phone struggles to reboot from any on screen commands.. Like if I'm in Android.. And hold power.. Click reboot.. Then say like recovery.. Or anywhere.. It just turns off... If I also do this in twrp.. Say like install a rom or supersu.. It won't reboot... But! After it turns off.. And I wait a while and power it back on.. The file.. Rom etc was installed. So I do now have supersu installed and busybox. But the issue remains..which is a unstable OS.. Nothing to do with it being custom os.. But there is something wrong with the booting process.. What can I download if any apks.. Or files to help this?

Might be stupid I know, but try wiping clean your SD card (back up a copy on your pc first) as well when you factory wipe and make sure that after that, you only add the files you need for recovery. Start up the phone after reset. To get a backup, if you're synced through google, you'll get everything back. If not, only copy your backup from titanium back into your SD card.
I went through a very similar situation last week. Long story short, it seemed the SD card had copied files which would interfere with the system.
Curious, did it happen after marshmallow update?
And did you try to downgrade back to previous lollipop version?

I assume it was Marsh that I was trying to Ota too. I was unable to boot successfully after that first try, so I honestly don't know.. I'm going to try your SD card idea. .. But once all that's done. Are you wanting me to redo a full rom install like through and wipe system, Davik etc etx? Or like wipe everything and start from like odin installing a recovery and so forth?

I ask these questions because.. What if I was to just take the sd card. And format the whole thing.. And out it back into the phone? I mean I might try that first then the other option.

Well even if you format and you put the SD card back in with all previous files, same might happen.
When you format, just wipe all. Then if you want to downgrade, you need to have the previous version bootloader and baseband FIRST prior to putting the firmware ROM.
A simple (restore) wipe would just keep you at current version. And you can't easily downgrade the easy way from marsh to lollipop. Believe me, I learned the hard way
Flash through ODIN

Semi-bricked device and can't flash stock

Hello guys,
suddenly my Note 4 won't work anymore, it freezes and reboots every 30 seconds. The sim card won't be recognized and in the settings things like IMEI and the carrier are unknown. Deleting cache in recovery didn't solve anything. I didn't do anything, the phone wasn't rooted, I didn't try to flash something, it justs got semi-bricked one day! Then I got a new battery and then it worked again! At least for some hours. Then it froze and rebooted again.
So I tried to flash stock with odin. Didn't work, even with the pit file and different versions of odin. It stops right at the beginning.
It's a N910F if you want to know.
And yeah, KNOX counter still at 0x0. But I don't have warranty any more.
Thanks in advance!

When did this start? Funny thing I have a similar issue. Yesterday my phone was fine. Had it with me on my desk until I went to bed, plugged it in and thought nothing of it. About half hour after I get to sleep the phone reboots, I hear the TMO gingle. I paid no attention to it, about 15 minutes later it does it again. I shut it off and this morning it all went downhill. Phone won't stay on, keeps rebooting. It sometimes freezes and becomes unresponsive.. you name it, everything that could have gone sideways has.

Probably your motherboard is dying.
Try to flash twrp recovery via odin and flash any rom and see if it works.

RIP mine is completely dead. Won't boot anything at all. Best of luck to you OP.

I have the same issue. Changed battery, nada. Flashed stock via odin, and it'll flash, and then it'll boot for a bit after flashing then freeze and go into bootloop, even if i try to boot into safe mode and try to boot into recovery. Flashing twrp with odin just makes it bootloop. I've tried every combination of things and can't get this thing to boot up properly. I'm convinced its a hardware issue.... perhaps processor going as someone above has mentioned?

910t won't boot

Hello everyone. I have encountered something I don't understand. My note suddenly turned off and wouldn't restart. I thought maybe my battery was low so I plugged it in and it started. I decided to get a new battery and charged it up same thing was going on sometimes it would restart and be fine I was running stock rooted rom twrp recovery never dropped it never messed with it. Then since i was having trouble I took it to a cell repair shop. I could boot to download and twrp but when i tried to back up the rom it would get to about 2 percent and shutdown. The only way the phone stayed on is if i am in download or twrp but i couldn't do anything repair shop couldn't help either. I was desperately trying to save some data off the phone when i gave up I said ok i will reflash it all goes well in odin it reboots then says applying update but never gets past the boot farthest i have got is the tmobile screen. then it shuts down and keeps vibration and trying to restart only to shut down and do it all over again. so I am now stuck in a boot loop it seems not sure if that is accurate. I have no idea how to fix this any ideas anyone i have reflashed the latest rom twice and everything should be fine but it isnt. I am wondering what to do next I tried to flash twrp but it didnt take and also tried cf oneclick root didnt take either but odin says success and pass. I am at the end of my idea list and out of google searches no idea what to try next. So I have come to the one place i may find some help XDA. Thanks in advance

your phone partition got messed up you have to put TWRP back and then go in wipe and then you have to do file repairwhen you fix file then ran back the stock firmware which will fix bootloader
then go back install twrp and install custom rom with root

there is the list of stock firmware try them see which one works with twrp, you have to install twrp first so you can fix the problem using repair files in twrp

Hello everyone. I have encountered something I don't understand. My note suddenly turned off and wouldn't restart. I thought maybe my battery was low so I plugged it in and it started. I decided to get a new battery and charged it up same thing was going on sometimes it would restart and be fine I was running stock rooted rom twrp recovery never dropped it never messed with it. Then since i was having trouble I took it to a cell repair shop. I could boot to download and twrp but when i tried to back up the rom it would get to about 2 percent and shutdown. The only way the phone stayed on is if i am in download or twrp but i couldn't do anything repair shop couldn't help either. I was desperately trying to save some data off the phone when i gave up I said ok i will reflash it all goes well in odin it reboots then says applying update but never gets past the boot farthest i have got is the tmobile screen. then it shuts down and keeps vibration and trying to restart only to shut down and do it all over again. so I am now stuck in a boot loop it seems not sure if that is accurate. I have no idea how to fix this any ideas anyone i have reflashed the latest rom twice and everything should be fine but it isnt. I am wondering what to do next I tried to flash twrp but it didnt take and also tried cf oneclick root didnt take either but odin says success and pass. I am at the end of my idea list and out of google searches no idea what to try next. So I have come to the one place i may find some help XDA. Thanks in advance

Befour flashing twrp make sure you uncheck Auto reboot....when it's done flashing pull your battery, put it back in the phone but don't power on....you want to boot right into recovery......then twrp will stick
