Xperia Z not powering on

Hi i have a sony xperia z that just doesn't want to power on when it's plugged into the charge the red led appears however that red led goes off after it's been in the charge in around half an hour of it charging it doesn't get recognised by the pc by flashtool or sus or pc companion not any hard reset or any of that work such as vol up + power and vol down + power or vol up + plugging usb in even if i hold the buttons for around 5 minute nothing happens, this phone isn't water damaged as all the indicators are white

Connect to pc's usb and leave it for some times.
And maybe you can explain more what you was doing before it happens like this.

i have connected to the pc and i also left it for more then an hour just when i first connect it to the pc it has a red led but later on that red led comes off and i honestly don't know i bought this phone in this state

I had the phone connected to the pc and that red led went off for a bit then it came back on

Are you using the original charger?

yes i tried multiple chargers aswell

i heard about dead xperias without reasons(in most of cases they turned off the phone and it never turn on again) maybe is better if you take it to a centre

Could it be the battery by any chance

bump

Help?

hold down the volume up and power button for 10 seconds, it reboots the phone
let me no if it works

Try what Andy194 said. Falling that try speaking to Sony themselves. Mine did that and they offered me a warranty replacement. Luckily the problem solved itself. As I was about to put it back in its box and send it off, it suddenly booted up fine, on its own.

My Z refused to charge when it was on 1%, as if its conntact with usb cable is not working well, happened once already but it returned to normal. So I decided to turn it off as it would turn itself off anyway. Plugged it in, but it didn't work. Used my Arc's cable and the red led light came up. I waited a bit for the phone to boot up to get to the charging animation, but nothing happened so I plugged it out and to my surprise the red light didn't go off and I can't do anything to turn it on. The phone is just rooted to 4.2.2, BL is locked.

Edit: left it plugged in my laptop and after 15 minutes or so it powered up. Yay T-T

[Q] RED LED Light, Phone won't start up

Hi guys,
I am having some problems. Last light, my phone ran out. I charged it, and when I woke up this morning, it won't start up. Every time I plug it into the charger, it gives a RED LED light at the top. Every time I pull it out of the charger, the RED LED disappears. It is running a pre-rooted version of Android KitKat 4.4, so I guess that means it has lost warranty...
I have not tried plugging it into a PC yet.
Please help, thanks.

Sounds like it's bricked. Can you get into flashmode when plugged into pc?

No, it couldn't be recognized by any programs (SONY PC COMPANION, Flashtool etc)
Very weird: a minute ago, it was charging, wouldn't boot up, still red led like before etc... And I didn't realize my laptop was on low battery and ran out, and my phone stopped charging. And the phone started up automatically after that? It had 3% battery, so it was not charging.

The battery keeps going from 3 percent to 4 and back.

The phone will not be recognized when off, when off keep pushing volume up and connect via USB to PC, it will be recognized in Flashmode and flash a new FTF 4.4 from Flashtool.
If it turned on then leave the phone under charge (Wall Charger) for at last 4 hours and check again, if it still give you problems then I will recommend to do a Factory Reset or flash a new KK and wipe everything, Data, Appslog and Cache.

Xperia Z bricked issue

Hello, my xperia z bricked suddenly while I was gonna flash a stock rom with flashtool (I used flashtool many times before). I just turned off my phone and then prepared flashtool to flash stock rom (kitkat). When flashtool said to connect the phone in flashmode, I just press the volume down button (while turned off) and connect the phone with pc. But nothing happens then. Phone doesn't response. Pc/flashtool couldn't detect my phone and also my phone doesn't response. No led light, no vibrations (holding volume up+power button for 5/10 seconds), no led indicator while charging. Nothing. Just died suddenly :crying:
Then I dissembled my phone and disconnected the battery connector from motherboard. Then I connected it again and plugged my phone to wall charger and charge my phone (no led light appeared that time while charging, phone just heated up) around 20+ hours. After that I got a red led light whenever I plug my phone into pc or wall charger. But the red led turns off after around 30 seconds. From then, whenever I connect the phone to wall charger or pc, red led appears and after around 30/60 seconds, it disappears again. I don't understand what does that mean So,
1. is it hard bricked or soft bricked?
2. is there really any chance to fix that problem by myself? I unlocked bootloader so there is no chance that sony will fix that 'brick' phone.
Any help will be highly appreciated.
Thanks guys.

You can try s1tool to flash your Bootloader.... Search the forum, u can follow the tutorial.... There might be a hope

just try to have the usb cable conected to your pc and hold the power button and volume up till it makes a vibration ,and then hold volume down even if it does not vibrate it should still conect to flashtools .

Z1 Bricked? Help...

I think I bricked my device. I previously had a custom ROM with Android 5.1.1. My phone is unlocked bootloader and rooted.
I was playing YouTube videos last night and fell asleep, but I didn't realize my phone was on the whole time so the battery died on me. I charged the battery for about 2 minutes to try turning the phone on, but it flashed red LED. I got impatient and did this...
1. As it was displaying battery, I unplugged my phone from my battery charger.
2. As it was shutting down (from pulling the charging cable out), I did a hard reset (hold vol up)
3. As it vibrated 3 times, I plugged the charger in.
After I did that, my phone won't boot, no LED, nothing. My battery can't charge it (turns on for about a second and then it stops. I charged it with AC for 30 mins. and no life. Pressed the red button on the SIM but did nothing, tried turning on the phone normally but nope.
Should I open the back?
EDIT: Finally on the computer, the LED turns on but it's red (stays on without pulsing).

Don't open the back cover just yet yet, it seems that you have a dead battery (fully discharged) so I'd suggest you to connect MicroUSB and magnetic charger together at the same time to force-charge the battery.
If you don't have a magnetic charger, and have a dock then all you have to do is pull it apart and you will find yourself a free magnetic charger in there.
Good luck!

No. Just leave it charged for 30 mins even with no les light, after 30 mins the red light will light up. U drained your battery thats why it wont turn on

Dead Z3+ Help

It was really tricky to get it to charge, but eventually it even showed the battery charging icon.
When I connect it to a wall charger i get a red light.
When I connect it to a PC i get green light.
If I press volume up + power the phone vibrates, I get a blue light and the computer detects something.
I have already tried flashtool and Xperia Companion but the software won't detect any connected device.
adb devices won't detect any connected device.
If I try to boot the phone it just gets stuck on the sony logo
Is there any hope for this device?
