Have a good read of this? http://xdaforums.com/showthread.php?t=1849170

It would suggest that the battery is flat. Let it charge in the wall plug for a few hours and see what happens
[Sony Xperia Z Ultra] showdown_counts:
I have let the phone to charge overnight with the charger that came with the phone. As I said before, with that charger, the red LED would turn on and then go off again. I will hopefully try the Chinese travel charger tonight with which the red LED remains solid.

The funny thing is , the phone had about 80% charge when it died. This is so weird :'(
[Sony Xperia Z Ultra] YawningCat:
What You Do Before It Happen?
[Sony Xperia Z Ultra] showdown_counts:
Nothing. Its like as if the phone soft bricked itself, probably by auto updating or something
[Sony Xperia Z Ultra] SpyderTracks:
Have you tried the reset button under the microsd flap? Press and hold for 3 secs.

I did read another user had an issue where the screen blanked for around a day, he left it plugged in and came back to it about 6 hours later and it was fine again.
[Sony Xperia Z Ultra] showdown_counts:
I tried that and basically all the other normal options. No use. The computer recognises it as a USB Input Device and for a second or two, the red LED comes up. Same thing when I am charging :(
[Sony Xperia Z Ultra] Andrewasth:
It's a battery issue most probably. I guess it doesn't show anything. Is your battery removable?
[Sony Xperia Z Ultra] showdown_counts:
I still have not opened my phone. I am looking at all the other options first. If everything else fails, I guess I will have to open my phone :(
[Sony Xperia Z Ultra] Andrewasth:
I know it isn't the best choice but I would suggest getting it to sony repair. So that your waranty isn't voided (even if you have bought from a local store you still have waranty ;)
[Sony Xperia Z Ultra] SpyderTracks:
Warranty exists with Sony for first year, no matter where it's bought, very true.
[Sony Xperia Z Ultra] caesu:
+1 contact your local sony, i had a similar problem, no fastboot/flashmode. locked bl/not rooted and my led only flashed red and occasionally solid red then nothing. plugging it into computer continuously played the disconnecting sound.

most likely hardbricked.

i also purchased my xzu from a local BST but as long as you have your imei, contact sony and theyll tell you if you have warranty. they required me to send in proof of purchase as well but like most say "play stupid" ( i said i received it as a gift and they said it was fine)

i got a brand new XZU after a week and a half sending it in.
[Sony Xperia Z Ultra] seijimaddog:
Thank you! One or two years ago my Z Ultra's screen cracked and I got a new phone. Decided to use it again, purchased a new screen and replaced it myself today. When I tried to move to AOSP (had root, bootloader unlocked, backup of TA partition), the phone bricked. No SONY logo, nothing. Did what you said above, Xperia Companion recognized the phone in flashmode and is now downloading the newest stock rom. I was so afraid of a hard brick, that living with latest stock without root doesn't seen so bad now hahaha
[Sony Xperia Z Ultra] lifehacker69:
Hey Friends, I have exactly the same issue. The red led just flashes up for a couple of seconds and this cycle continues. My battery was a bit swollen up and the back glass cover opened up a bit. Still battery was working fine. Two days ago I tried nougat aosp on it and after leaving it idle for 2 hours, it was bricked. I can enter into flashmode and flashed stock LP as well as KK but it does not boots up. Is it definitely battery's problem? If yes, where can I buy original or near original battery for it?
[Sony Xperia Z Ultra] SUPERUSER:
The battery is dangerous and should be removed. Be careful because the battery can burst into flames if the bloated cell get punctured.

Use tools with caution and take your time.

Lipo cells expands as a first safety trigger. Instead of going strait to venting or venting and burst into flames.

Its a safety feature if they are charged with too high current or if the cell is drained below its 2,22 volts and is brought back to life with a normal charger that puts normal current on the cell. Then even 400mA in this scenario is way too much current to start charging a drained cell with.

But the battery should not be the issue that your phone is not booting. How did you flash stock rom? With Flashtool?
[Sony Xperia Z Ultra] lifehacker69:
Thanks friend. I think will keep my device away for a couple of days until I find replacement. The battery swelled up when about some months ago I soft bricked it and volume buttons were unresponsive. Even the hard reset was not working. I had to open the back panel and remove battery. Then somehow it went into flashmode and it revived. But few days later the battery swelled up. I have been finding replacements but even the service center guys aren't able to help me.

Yes, I used flashtool. Somehow, once in a while it went into flashmode when I removed battery and reinserted it. I had flashtool ready and flashed full stock FTF.
[Sony Xperia Z Ultra] SUPERUSER:
Perhaps you agitated the battery somehow when you opened your device? It seems that the swelling is related to when you opened the back panel.

Yes the phone goes into flashmode when you reconnect the battery if the usb cable is inserted.

We do have access to the service manuals so all guides and parts are available to us to read.

Thanks friend for all your hard work. Just ordered one.

And after two days of leaving my phone in drawer, I decided to charge it. It is now showing a constant red led. But it has been some hours and phone doesn't even turns on or respond when I press power button. Should I continue to charge it or wait for my replacement?

The only issue I have with this method is that if I connect a bluetooth keyboard, I have to switch the toggle back, or lose half my screen to the on-screen keyboard when I have a physical keyboard. Also, unless the Select input methods is available in the drop down menu, I haven't been able to locate this setting by another means. I welcome someone to find another method.

I had the same problem as wmulle using a bluetooth HID gamepad.

[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] KatanaMan:
I'm bone stock, no root and have recently applied the L720VPUFNAE update. Since taking the update, the phone has had nothing but problems. When awakening 50% of the time I will get nothing but a black screen and will have to hard boot the phone. The other 50% of the time, it's extremely slow to accept my unlock code. Half of my home screen shortcuts are gone, just disappeared. Battery life is terrible, just a few hours of life. I've browsed here for solutions and have seen some people having similar issues on other sites, but no solutions. Is there a way to force the update again to see if that fixes it? Any other solutions aside from factory reset? Often times the phone will ring and I cannot even answer it because it won't wake up properly!
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] daniel4653:
I would suggest to factory reset the phone then proceed to Odin NAE tar that is available in the development section. Of course back up important things just to be sure. I had bad battery life for a few days. Until I discovered that it was clash of clans that was draining my battery. On Wi-Fi with the screen off it would drain about 4% since using greenify on it my battery now doesn't drains 0-1% under the same circumstances. You might have a rouge app that is draining your juice.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] hshendon:
I am having these same exact issues. Really don't want to do a factory wipe if possible, but I am starting to think I may have to do it.

Also, the wifi issues have not been fixed with this release.

Anyone using anything like Juice Defender since the update -- is it helping with battery drain?
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] daniel4653:
What Wi-Fi issues. So far I haven't ran into a single one on unrooted.

try greenify it works wonders.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] KatanaMan:
After the last update to 4.3 a few months back, I also had some serious issues which were only solved by a factory reset. I hate the thought of doing it again, it's so much work getting all the tweaks and settings back the way they were. But it appears that may be my only option. Each OTA patch Samsung has released has been a disaster, it's getting to the point where HTC might be back on the menu for me.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] w7excursion:
Bit dramatic there. If a factory reset fixes it there's nothing wrong with the update which you might have to do with an htc update also.

I got the notification just now. How can I make it go away?

Google services framework is trying to update it.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] KatanaMan:
As a followup to my own post, here's what I tried to fix it:

1 - A full factory reset with data wipe. Unsuccessful.

2 - A visit to the Sprint Store to have them nuke & pave the device to complete stock (it already was, but hey). Unsuccessful.

3 - Remove the Exchange Active Sync account. Successful.

To me this indicates a severe issue with the stock EAS client that comes with Kit Kat. If you are having similar problems to me, where the lock screen takes 20 seconds to appear, battery drain is enormous and the phone has problems "waking up" from screen power-off, try removing your Exchange account.

I might have to give something like Touchdown a try, I'm open to suggestions of a less costly alternative though.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] chris-allen:
once i remove it.....what will become unusable??

---------- Post added at 09:17 PM ---------- Previous post was at 09:14 PM ----------

just deleted the exchange services app.....is that ok? i dont use email on this device anyways except the gmail.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] KatanaMan:
I don't know if it's the same for you, but I had the native Exchange Active Sync email configured on my device with a enforced PIN lock. When my EAS account was configured under KitKat, the PIN lock screen had all sorts of issues, the device would get hot and battery life would go out the window. I deleted the EAS account, not the service.

Since then, I switched to Nine for my Exchange mail and the problem is completely gone. To make sure I configured the native app and deleted it a number of times. Each time the native EAS email was configured and the lock screen set, the phone crapped out. Nine enforces the same PIN lock policy, however my lock screen no longer freezes and kills battery. I am using "device security" with Nine, not "account security".

I'm honestly surprised to be the only one to experience this after combing through this and other forums. It means there's either something unique about my phone hardware/config or my Exchange server that causes the PIN lock screen to crap out. I don't have any lock screen widgets active.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] insanity213:
My wife has a bone stock S4 with the same problems. We flashed the stock kitkat tar with odin and wiped data which didn't help. She doesnt use exchange, just gmail. Im trying to convince her to move to a gsm provider and get a nexus. Im Effing done with sprints garbage network and garbage bloated roms. Any suggestions before I set this phone on fire?
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] viper126:
So I had the same problem and this drove me crazy. I tried wiping Cache from OS, from Home key+Up volume+power, I tried a factory reset, I event tried applying the 4.4.2 patch via ODIN. I tried removing the lock screen and company email. The problem kept coming back.

Today however I brainstormed with a coworker who also has a working 4.4.2 S4 on ATT. After comparing settings for the lock screen we noticed the new swipe option and turned that on. What a bad move... that locked the phone up hard to the point I kept getting "com.android.systemui" stopped responding. I had no choice but to pull the battery and reset a few times and it didn't fix the problem. At last I had the idea to pull the SD card and boot the phone. That worked!

Everything worked exactly as snappy as it did with 4.3, so I rebooted a few times, got some texts, turned on the lock screen in order of swipe, and then PIN. With everything working I turned off the lock screen and put the SD card back in.

No problems....

rebooted

No problems...

turned back on the lock screen and all has been running well.

I'll report back if it slows down in a few days but at this point I've come to the conclusion that this problem has to do with the SD card. My thought is the Symbolic link which guides the OS to the SD card stay in the system even after the reset or upon reapplying a Play app. The removal and boot without the card removed the symbolic link and reset all the ExStorage to the new Kernel/OS version.

Hope this helps anyone suffering the same problems!!

Just wanted to throw my 2 pennies of experience in the ring. I'm on MF9 Bootloader and just recently moved to an NAE rom and kernel. I at first left my modem MF9, and everything was fine. Yesterday I flashed NAE modem and thats when the lag/black screen/CPU continuously working began. I cleared cache and Dalvik and still no fix. Being that I had just flashed the modem, I flashed back to MF9 modem and the issues went away. I then repeated the NAE modem flash and same issues came back. I'm back on MF9 modem and back to normal so far. I will also say that after flashing modems, there is a pop-up at boot that says something about android updating(no this is not the normal message when you clear dalvik). I dont know what the exact issue is, but for now I'm going to stick with MF9 modem.

Edit - Before anyone asks, I did check the MD5 of the NAE modem. That was my first thought is maybe a bad download.

[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] dpotter38:
Same thing happened to my S4. Moved to an NAE ROM and also installed the NAE firmware. Could not figure out why this slow down was happening. After some googling I ran across something that suggested installing the MF9 firmware again. After flashing 3 times to actually get it to stick, my issues went away.

I don't understand why some phones don't like the NAE firmware, but I just chalk it up to technology is weird sometimes and have accepted it. It works fine and good signal with the MF9 firmware, so I'm not worried about getting NAE to work.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] daniel4653:
I did just notice about 3 days ago that my battery life was dropping a lot without even using it. This is on stock unroofed NAE. I used to average 15 hours with 3.5hrs screen time. Now I am lucky if I can get 7 hours with 2 hours of screen time. It might be my phone so I might go to A sprint store to see if my battery is failing. It isn't a rouge app that is affecting it , not low signal( have an airwave). I go.to sleep with 90% and wake up 6 hours later with around 50% or less.

Hey guys, so I have a big problem. If found my Nexus 5 randomly turned off when I was at work. Tried turning it back on, no luck. Tried charging no luck. Tore it down to check everything, looks fine. Then I plugged everything back in and left the back cover off, and it makes a clicking noise when the power button is held but nothing. It stops clicking after about 5-10 seconds.

What's even more problematic is that my device is rooted with a custom kernel (I was running unlocked bootloader, root, stock rom with Faux Kernel for the best part of 3 months problem free) and I'm sort of worried about sending it back for warranty. Any ideas what to do?

I've picked a nice photo that I've taken as the background for my Today screen, by choosing 'Set as Today Background' from the context menu. Looks lovely. However, when I soft-reset, it reverts to the previous picture I had! Any idea how to stop it happening?
[8125, K-JAM, P4300, MDA Vario General] meschle:
Not sure why that is happening - the today screen background is called tdywater.gif and it changes when you change your today theme. (tsk files are just like cab files and have an inf file and a couple of gifs.)

You could make your photo into a gif and rename it tdywater.gif and try it that way - the dimensions of the gif is 240 x 287 and place it in \windows on the device.

Or you could create your own theme - use themegen ce (free) or there are others.
[8125, K-JAM, P4300, MDA Vario General] ZeBoxx:
make sure you're not performing that soft reset too soon after setting the background. Alternative to soft resetting, press&hold the standby button.. after a few seconds it asks you if you want to shutdown - choose yes. Then wait a few seconds again, press the standby button and it should come back on and boot up.
