[Q] z2 screen flickered and then dead screen - Xperia Z2 Q&A, Help & Troubleshooting

Very weird thing happened to my Z2 a couple minutes ago. I was in the bathroom playing clash of clans and was about to take a shower and left my phone in a place where it wont get wet. When i was supposed to check my phone i just noticed a dead screen. Then i turned it off via volume up and power. When i turned it it on the phone screen flickered as if it was about to lose power and screen also is not responsive.. I thought turning it off for a few minutes will bring the phone back to normal but it didn't.. My phone now will boot up to the xperia logo and screen will off.. i tried calling my phone and to my surprise the call feature is working.. Does anyone have any idea as to what may have happen? TIA

try repairing device via sony Sony PC companion
if the problem persists then contact sony customer support as your device should be covered by the 2 year warrenty that comes with all xperias

Envious data supposing this is a hardware issue will the warranty cover the replacement of the front panel e.g screen if needed? i flashed my devices with a 314 RU firmware should i flash it back to original software before going to Sony service center? Thanks in advance

i reflashed my firmware via flashtool but screen still unresponsive DAFUQ

Any modifacation of the device not from sony will void yoir warrenty, flashing new firmwares isnt detectable but bootloader relocking may be

Will Sony be able to tell I rooted phone if it wont Turn on and wont recognize usb?

Well as the title says i rooted the phone a long time ago. I noticed my phone didn't charge yesterday so I started messing with it and realized it would need to be sent back. so I wanted to start unrooting, but I couldn't connect into flash or usb at all. I did manage to start a flash once , but then it lost connection half way through and the phone doesn't turn on at all now. I can't wiggle usb or anything at all to get it to recognize so I imagine the board or something need to b replaced. question is will sony be able to tell my phone is rooted in its condition and if the replace board i'm in the clear right? thanks guys!

i think if it doesnot turn on they dont bother repairing it.it is happen with a printer i giveback to bestbuy and they replace it right away without even plunging to power.
oh yeah when I say doesn't turn on I mean it vibrates as usual when u try to power on, but it goes no where. no sony logo or anything.
Oh no. Just tell them the truth, hopefully they don't care... wish ur phone good luck...

Well technically rooting the handset does void the warranty. However, if there's no way for it to turn on, I don't see how they'll be able to tell!

I have tried the SE update service and the phone won't go into flash mode because it seems that the usb port is faulty and loses connection. I'm just sending it in and hoping it gets by them. If not I will just pay for the repair I guess.

This happened to me too. USB port was faulty, couldn't charge, couldn't flash. Vibrate on power key and red light flash but no Sony logo or anything. I borrowed a friends fully charged battery and got phone turned on. Entered recovery and wiped everything, system, data and cache. Then sent it off for repair as it was then a blank phone. They just sent me a new one
Sent from my X10i using XDA App
Thanks....This eases my mind a little. My wife actually has an x10 as well and I tried her battery as well and it won't go anywhere. It just doesn't work so I am fairly confident that they will jsut be repairing or sending me a new one. It goes out tomorrow so my fingers are crossed. Thanks again for the insight everyone.
Update: I called Sony today for an update on my repair and I was told there was no record of my service request. The support agent I spoke to assured me he would call me back by the end of the day with an update. Well I was waiting and UPS arrives suprising me with my phone The packaging was verrrry bad. It was in a flimsy box wrap in some thin styrofoam wrap thing. The box was dented pretty badly, but the phone seemed to be in working order. The best part is they just sent me a straight replacement. So I put sim in and power her up and it's asking for an unlock code...AHHHHHH!!!!!!!! Spoke to Sony, AT&T and Rogers to try and get them to provide one, but they wouldn't give me one. So now I am waiting for a code to be sent to me from an online company. Hopefully will be up and running within the next 24 hours. I'm just happy it was replaced no questions asked. It actually was sent out to me the same day it was received so that's some quick turn around time.
They can always check for root eeven if it doesnt turn on how? Via the sdcard they take it out and plug it into a sdcard reader then onnpc they check for stuff unusual like superuser app or anything revelant lol

Before you send it in they tell you to remove sim, sd card, battery and back cover.

And besides, files related to root are not stored on the SD.
From release notes on emma you can see that from 2.11.4 version they added detection of rooted phones..
So answer is yes, they can detect if phone is rooted, ofc if they are able to read data from phone..
I have tried 3 different unlock companies online and none have been able to generate a unlock code for my new phone. This is unreal. I dodged the rooted phone issue easily since they couldn't power on phone, but they sent me back a locked Rogers phone and no luck getting it unlocked yet. This sucks :-(

[Q] dropped my sk17i (max 20cm) tries to boot, fails

So I managed to drop my mini pro on to the table from max 20cm. The phone won't even try to boot with only the battery, when plugged to the wall the phone starts to boot, but looks like it runs out of power quickly. It shuts of a few seconds after the sony logo has dissapeared. I can enter CWM, but again only for a few seconds. Any ideas what to do or try appreciated!

You "managed" to drop your phone???
Anyways, it definitely looks like a hardware problem to me so better flash stock firmware and relock bootloader (if unlocked) take it to Sony service centre. I hope it's not some major fault.

It slipped out of a window mount somehow. I imagine, it's quite difficult to flash a stock rom and lock bootloader if the phone won't stay on for long (pretty much a second or so of useful time in CWM) and my computer doesn't even understand that it's connected.

Take it to the service centre man. No other solution if it's a hardware failure can you get into fastboot? If yes, try to flash some other kernel and try to boot. if this fails, then just take it to Sony, no other solution

Then just take it to Sony service centre... Those guys will check for some loose connections...
It might be just a small circuit broken...
How will the service centre employees know that your phone is Rooted or not... If it isn't staying on...
And I suggest you to take your phone to some local but trusted serviceman (if you know any in your area) for a second advice...
Sony service centre charge too much money... And a second opinion is always good

Thanks for your advice, both of You. As magically a 20cm drop broke my phone it also suddenly came alive. So far everything seems to be working. Hopefully it just had a concussion or something like that. I of course got a mini heart attack. Now I'm only wondering if I should flash stock ROM and lock bootloader and still get it checked out.
Thanks again guys!

RED LED might indicate that your Battery has drowned. Charge it and try again.
It's your battery
Sent from my Xperia U using xda premium
No the red light is normal, always comes up when the charger/usb are first connected when phone is off.
@bibhu059, you change your story, in the other thread you said you have flashed another TA partition, maybe you explain exactly what you did.
And what happen when you try to connect with flash or fastboot modes?
Someone suggested to take the battery out, have you tried that?
As you wrote in your PM to me, you restored a TA backup from someone else's device. This hard-bricked your device, which you could have prevented when you read the FAQ first. Sorry but there is nothing anyone else can do for you at this point. Only option left is to send it to Sony - tell them it suddenly didn't turned on anymore - and hope for the best.
There is no recovery from a hard-brick.

Yes. But you just say your friend took your phone and you did not know what did he do with it. When he returned your phone, it was like that. My friend actually took a rooted s3 to a samsung service centre and they knew he rooted, said he found custom binaries. When questioned, he asked "whats that?"

Of course they can, makes no difference they can and should fix it anyway,
Losing warrenty does not mean you are not entitled for service, only that you may have to pay for it.

They will charge for replacing the motherboard. One of my friends with xperia s had recently had a dead phone and the motherboard change costed his new phone 200 bucks($) and I guess now u might want to read before doing such stuff

Dead xperia u

Hi guys, i m having an xperia u running ics. it fell from my hands and froze so i took the battery out to restart, since then i cant turn on my phone when i press the power button it just vibrates once an there is backlight on the screen but nothing else not even the sony logo. Sometimes the illumination bar flashes green. i tried everything from removing the battery several times to flashing. the flashing proccess completes with no errors but the problem is still there. Any ideas? i have no custom roms or so only rooted with flashtools...
It seems the screen was broken take it to any nearby center to repair its hardware

Thank you for your answer, but i m pretty sure that the screen is not damaged maybe motherboard, although i would like to be sure that there is no software problem if possible... from what i have read when the sony logo doesnt appear means that the kernel is dammaged... is there any way to flash xperia u stock kernel first and then flash the firmware? also i had asked sony to give me the code to unlock the bootloader, but i never used it and didnt unlocked it, have i lost my warranty only for asking for the code?

Finally, the problem was the screen and the touchpad, they changed both at the service point under warranty, as they had no obvious damage i guess... is this a common problem with st25?

So my phone won't turn on.

Sooo I recently got a Z Ultra. I decided to try putting it into water. To test out, no? Then the screen became darker and darker, now it won't turn on and it stays black. It still works if I plug using USB. What should I do now?
what about warranty ?!
Don't plug in the charger. Potential water + electricity is not a great combo. Open the right flap (the one where you insert your SIM and SD card) and check the color of the small square. Is it white or pink/red?

It's white. And on the box, it said "Water resistance". I'm not going to be fooled by bad advertisement. I'm sure that all the places I need to close are closed. The phone still vibrating. It just that I can't boot it up and the screen are black. Sometimes I hold Power and Volume Up then I hold Power, the Sony logo flickered.
Edit 1: Okay I managed to turn it on. Normally. So all the buttons were working normal, the touchscreen buttons such as Back and Home and that other button works because it vibrates when I touch it.

Yeah, you're on a very old firmware. Update to 4.4.2 (.757). The earlier firmwares had issues with some "SOD" (Sleep Of Death) which means that the display would stop working, but the phone would still be on. It was solved a long time ago, but you're still on an old firmware, so go ahead and update using Sony PC Companion.

I have no idea since i've never had any issues with SOD, but you're still on an ancient firmware, so update to the latest one or don't even expect to get help. I'm not going to try to help you when you can solve it (possibly) by updating to a newer firmware where this has been solved. If it's still not working after the update, THEN we can try to figure out what's going on.

Kay, I'm doing exactly what you said. I'll pray.
So yeah. It's still blackish. "Water resistance". And the water still somehow leak into the screen.
So water got in? What color is the water indicator?
- White = No contact with water
- Pink/Red = Contact with water
Your warranty is also dead if it's pink/red.

My water indicator is white. I brought it to my country Sony Center, They said the contact from screen to the machine is bad (?) They said that they must change the screen but they don't know if it'll work. I'm in a country that's different from where I bought the phone so I have to pay. A lot.
Will it be eligible if I send it back to where I bought it for warranty?

I'm living in Vietnam. I just talked to UK's Sony Customer Service and found out that my phone was built in italy and is eligible to go through repairs. I don't know if I have to pay for repairments or not but it should be free because it's the manufacturer's fault, not mine.

Read my post in Xperia tablet Z forum. I think it can be repaired through pc companion.make sure that it can be set in flash mode.
what i did was : i turned off my tabZ for 2days. Put inside the plastic container with 4 bags of desiccants.. After that, since i can boot it up occasionally, i repaired it through pc companion...hope it helps some of you guys..

So Sony doesn't care about me nor my faulty device. They adviced me to just throw 200$ and fix it here rather than taking responsible and fixing my device from the UK. It's THEIR FAULT. WHY DO I HAVE TO PAY AGAIN WHEN I HAVE A FAULTY DEVICE?
Here's the talk between me and the agent. I'm really mad atm.

The agent did tell you the truth. You purchased your phone in the UK, so the warranty is valid in the UK, and not in Vietnam. They do not cover mailing it for free outside their area (which is logic), so you have to pay a regular fee to send it to the UK. By paying and sending it in a package through the regular mail, you should get some insurance too. I'm in Norway and whenever I send anything as a package (and pay), it's automatically insured for about $1000, so if it goes missing, they'll pay.
There's nothing unusual here. This is why you should think twice before you buy any electronics from a different country than yours, and you just had extremely bad luck this time around. Sony UK can't do anything because you're not located in the UK. It's not as straight forward as you like to think. You can either get it fixed in Vietnam or you can order the parts yourself and do it yourself. I would advice you to not do it yourself though.
