Phone is completely unresponsive - Sony Xperia Z Ultra

Went to restart the phone and now it appears to be completely dead. Won't switch on, and is completely unresponsive to any input: usb, hard reset switch, power etc. I have plugged in the phone to a computer as well and there is no "usb detected" on screen or anything. Is it reasonable to assume that this phone is fully bricked?

Did you try th red boton near the SIM card?

Yep

Try holding the power button for an extended time period. You can also do a ftf stock firmware.

Holding the button for over a minute does nothing, and the phone is simply not detected by any computer I plug it into. The orange LED doesn't even come on when I plug it into a charger :/

Possible that the battery went completely flat? Try plugging it into an AC wall charger for at least 6 hours and see if anything happens.

My wife's Z went dead during an update via PC Companion (light went out), and it didn't boot or show any life sign.
I used the Sony PC Service (only for PC), restored the phone to the original FW and all went well, nothing was deleted from it. Try it and see...

[Q] My ZU wont switch on. Red LED

This morning, my Z ultra died on me. It wont start, no vibration, no use pressing vol + power buttons and the red switch. I was neither rooted or bootloader unlocked.
When I tried to connect it to my laptop (Windows 7), its shows as a USB device. The red LED flashes up, the computer finds it and then lets go of it again. Again in a few minutes, the red LED goes up , the computer makes the connection sound and then the red LED goes off again. This cycle goes on and on.
I cannot use SEUS, Flash, Fastboot or do anything. I have checked various forums and apparently I have not hard bricked the phone as the LED still works and the computer recognizes the problem. But no one has given any concrete solution.
When I connect it to the charger which came with the phone, the red LED pops up and then goes off again. I dont know if its charging. HOWEVER, I have used another Chinese Travel Charger, and then the red LED stays solid as if its charging. I dont know what it means.
Please help. I spent a lot behind this phone. I dont want to be left with a brick
It's not an issue if it's completely stock is it? You have your warranty, but i understand that i sucks to have it shipped in for repairs for god knows how long. I had a similar issue some time ago, but i'm bootloader unlocked and what not, so that was pretty easy to fix. You're completely stock though, so it's a little harder to do anything.
What happens if you hold VOL UP when you connect it to your computer? Does a blue LED light up? If yes, does it stay on, or does it disappear? What happens if you hold VOL DOWN when you connect it to your computer? Do you get a blinking LED and then nothing? That's normal, and it's going into Flashmode. If you can get it to stay in Flashmode you'll be able to re-flash a ROM in Flashtool. But be 100% sure to have enough battery, or else you'll be in danger of hard bricking it.
So..
- Plug the wall charger in and charge it for a couple of hours (2-3 hours)
- Try to kick it into Fastboot (VOL UP when you connect it to your computer). Look for blue LED.
- Try to kick it into Flashmode (VOL DOWN when you connect it yo your computer). No LED.
Hi LordManhattan. I dont have any warranty as I brought it from a local reseller .
Whether I press Vol UP or vom DOWN when I connect to the laptop, a red LED pops up, there is a connection sound and after that the red LED goes off and and there is a disconnection sound.
If I leave the phone connected with the computer, the phone gets connected after 2/3 minutes, there is a connection sound and then there is a disconnection sound again . Any clue what I can do :crying::crying:

just a small note or two:
Flashmode the LED should go orange, then blue then off within about 1second then it is in Flashmode
To get into either of these modes the phone has to be powered fully OFF, press the red reset button before charging to make sure, then again just before the above steps.
It sort of sounds like a corrupted loader

Have a good read of this? http://forum.xda-developers.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
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 :'(

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.

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

It's a battery issue most probably. I guess it doesn't show anything. Is your battery removable?
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

Warranty exists with Sony for first year, no matter where it's bought, very true.

+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.

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
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?

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?

My Z2 just died. HELP.

So I've been using my phone as per normal, and it suddenly switches itself off and wont turn on.
If I plug it in to charge (the batter was at 40%) I just get a blinking RED LED.
Any help / ideas guys?!
Try to press volume up and power in the same time. If it vibrates 3 times it should start normally...

Hi Fenix
Have tried that with and without a charging lead connected and no joy. The red LED just continues to blink.
Have also tried, again with and without charge, to press the red button next the sim card slot and no luck.
How about volume down and power?

Same result.
Planning to leave the phone OFF charge all night and see if that helps, and then maybe do the opposite and keep it ON charge for a few hours maybe.
Any other advice?
Have you tried a system reset
(you can use sony PC companion to do this)
(repair device)
I have this same problem.
I have reset and re installed the rom via pc companion and same problem.
Basically the phone will not charge via the magnetic connector at all.
if you switch off the phone it will not stay off, it keeps turning its self back on again and boot looping: displaying the sony logo, then off, then sony logo again.
If you hold the power button down for 20 seconds whilst on a Sony logo, the phone boots to the experia logo and boots normally.
Problem is the phone will NOT switch off and half the time it wont come back on. Its basically a lottery on whether the phone will come back at all.
Update - managed to get the phone switched on after leaving it on charge all night. Had to hold the power button down for 30 secs to get to my home screen as otherwise it was just looping to the Sony logo.
However, now, the phone is not charging - it detects that a charger is connected but the battery level is not going up and the LED is constant orange.
What to do?
I would flash a.2.69 firmware if you don't have it already.

I'm a newb with these things - is there link for how to flash?
Not sure if it makes a difference but this phone is from Vodafone and I believe they've locked the bootloader or something similar?
Also noticed that the phone 'thinks' its still charging even without a charger connected - and the orange LED is constant.
Looks like the battery is kabooshed?
I think u should give the phone in for warranty.

Adding to the above.
Received my Z2 on O2 onFriday 2nd, Tried charging it this morning and red charging light was on then started flashing.
That was trying to charge via a usb cable to the magnetic contact.
Re tried using standard usb cable.
Will not start regardless of what I do, on button, on + volume up, on + volume down.
Trip to O2 after work tonight to take it back.
May be a problem with the magnetic charging system, somehow shorting something out, for me anyway.
Same here, Need to return it to T-Mobile.
Same issue,
Went Off, never to be able to turn the phone on again.
When connected to the Charger, the red light blinks faster.
When connected to USB red blinking led, blinks slower.
Does not go 'On' anymore.
Recovery from pc compannion does not work.
The Update tool send by the sony technical suppport also did not recognise the device.
Windows does not recognise it.
Volume Up + power does not work
Volume Down + Power does not work
Volume Up of Down (phone turned off) connecting with USB does not work.
Red button next to the sim card does not reset the phone.
It is a Brick now, hope sony is good and replaces it with a NEW one.
I need help .. i was normally use my sony z2 d6503 and it turn off itself and i cant open it even if i put it charge only red led no logo no charging logo .. all black ..

Cant turn on

Hello!
Installed CardHDRom V5 yesterday with about 50 % battery in this order. Flashed recovery, kernel, super su then rom, fromt this thread : http://forum.xda-developers.com/gal...p-recovery-2-8-7-1-g925f-android-5-1-t3144866
WAs going to charge the phone this morning and put it in the charger and fixed breakfast for about 10 min.
Went back to the phone and the screen was black and the led light is shining green. And now i cant manage to turn the screen on Any ideas?
The led light is on even when the charger is plugged out i cant get the screen on, neither recovery or download mode
press volume down and power until you get a response from screen, then release power and keep pressing volume down. It will boot into safemode. You can try to figure out what went wrong from there or just reboot the phone

Screen went black, no life signs since.

Hi,
So, today I took up the phone from my pocket(as usual) when I noticed the screen wasn't turning on.
I've been using all day without issue and I haven't dropped it or anything, still it wouldn't wake up or show any life signs.
I've tried all the button combos I can think of and holding them for long periods of time. I've also tried having it connected to the charger for a few hours but it does not change in temperature so I'm pretty sure it's not taking up any charge.
Is there anything more I can try before sending it to Samsung for repairs? Doing that is a bit of a hassle since I moved from Europe to the US recently.
Thanks on beforehand!

To me it seems like the battery is not connected anymore and that it needs to be reconnected inside, since it does not even take charge.

Poco overcharged overnight

hi guys i plugged my phone in original EU wallcharger at 9pm with battery status 51%, unplugged it at 1:30am(after 4.5hours) after that when pressing power button it was showing poco f1 logo + discharged battery logo at the same time it blinks and shutdown
now is completely dead zero reaction for any keys combination
Can i try do anything or should send it on warranty?
I haven't heard of this happening with an F1 before, but it happened to my old Moto g5. I suggest you leave it discharged for a while to fully run down then plug it in with the phone powered down for 3hours or so.
See if it will power on then
With the g5 I read that some battery protection feature was prone to triggering - with time it would reset
Good luck!
Try recharging it again, use different cable+wall plug.
Try powering on whilst plugged in to charger to check what's happening.
If not improving then it's obviously not normal, maybe a battery failure. Try to backup files if possible and get replacement under warranty.

Are you sure you turned ON the switch after plugging the charger. It happened to me as well. After leaving the device in charge for an hour, I realized I didn't even turn on the switch from the main board.

Yes. So what we do is, we first insert the charger in the plug and then we turn on the switch which is located just beside the plug point. The plug point will only start passing electricity once we turn on the switch.
Any update?
Completely dead....
All solutions didnt work, thanks for help guys.
