[Q] Phone will no longer boot - Xperia Z2 Q&A, Help & Troubleshooting

Hello guys, it seems I've been a bit stupid and dropped my z2, the phone will no longer boot. I've connected the phone to the wall charger thinking my battery was just dead, as I had left the phone for a while as it had slipped out of my laptop and I thought nothing of it.
The phone will display the sony boot screen however the phone will just restart, I've tried to reset the phone by holding down the power volume down buttons but that doesn't seem to have done anything. I tried the red button where the charger is but that hasn't done anything.
Does anyone have any ideas?
Thanks, Pineapple

The phone won't connect to the PC so how would I be able to reflash it? Also it seems once the charger is out the phone will no longer boot

hardreset your device by holding down the red key under the left flap
try again connecting to PC in flashmode

Cant Download Mode, stuck in phone--!--PC, grey battery.

My phone is a Telus t959D
I am stuck at the phone--!--PC screen. 3 button combo does not work, please do not give me other 3 button combos because it will not work. I think i need to fix this battery problem first and the download mode will come itself.
Plugging it in to the usb gives me a screen with an empty grey battery, with the progress circle in the middle frozen.
I cannot go into download mode because when i connect the usb, the grey battery pops up.
If i turn the phone on with no usb, i get the phone--!--pc screen.

Uninstall your current installation of Kies and any samsung drivers, restart your computer, reinstall Keis from http://www.samsung.com/ca/consumer/...TLS/index.idx?pagetype=prd_detail&tab=support and download the drivers via that, restart again and check the results.
hey sendan thanks a lot. Before i do what you said i should do, how will the computer recognize my phone if it is only on the phone!PC screen because kies cant even recognize it right now?

No, without the battery the screen is just blank because it is off if that is what you meant. If you meant if i pull it out and put it back in, then it goes to the Phone!PC screen without a USB connected. If i reinstall the batter again WITH a usb, then it freezes at a grey battery.

you suppose to get into download mode without the battery in.
power off and pull battery
plug usb cable in
hold vol down until the yellow triangle appears
I took out the battery, plugged in the usb, and held the volume down button. Screen stays black (left the battery out)

ok.. Are you using the factory usb cable? If so, then unfortunately you may need to do one of the two things:
http://forum.xda-developers.com/showthread.php?t=1288093
or get a "Jig" and jumper the usb pins.
alright i'll try those out. And i recorded myself doing the methods and the screens i get.
http://www.youtube.com/watch?v=8ZxCzxb5RT8
Okay I watched your video...instead just take the battery out and DON'T put it back in, your computer will supply the power. Now make sure your holding the volume down button BEFORE you plug it in, and continue holding.
Or plug it in the wall adapter if you don't have powered USB Ports.

Actually I did a bit of reading, since I got stuck at that screen a long time ago, and I remember connecting to Odin at the Phone ! PC screen. You should be able to connect to Odin because it's still considered download mode. If it doesn't work you should re-install the drivers that I posted before.
I can almost guarantee it will work unless something else is really broken.
Edit: Here's some reassurance to motivate you - http://forums.androidcentral.com/t-...s-hacks/79287-odin-works-phone-pc-screen.html
there's a feature in heimdall to try and kick it out of that screen.

[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 :'(

Nothing. Its like as if the phone soft bricked itself, probably by auto updating or something

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

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

Warranty exists with Sony for first year, no matter where it's bought, very true.
Sent from my C6833 using XDA Premium 4 mobile app
+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?

[Q] Z ultra won't turn on

Hi.
Today my Z ultra turned off while on locked screen. When I try to turn it on it is not responding and it do not respond when I connect it to the charger. I have tried to hold the power button and both the volume up and down at the same time, and it came a vibration and the Sony logo showed and it turned off again. Now that won't work either. I also tried to hold power + volume up and power + volume down. Nothing happens. When I connect it to the computer, there are a sound on the computer who tells something is connected. The sound comes again and again, but the phone does not show up on the computer.. What can I do?

Edit: I also tried the red button beside the sim-card slot.
Try connecting it to a wall charger, then press the red reset button. leave it to charge for several hours

I tried leaving it in the charger over the night with no success.. When I first connected it, the light turned red and the phone turned on, to the Cyanogenmod logo and turned off again.. Now it won't respond again..
The other thing to try is to see if it will enter flashmode or fastboot
Connect to PC
Hold the vol. up key
Press the hard reset button

I suspect that either the battery or it's controller are dead, can you get warranty on it? They may not take it with not stock firmware on it...
You could try the rubber band trick:
Setup flashtool to flash a FTF
Connect the phone like normal, but have a rubber band around the vol down key.
Leave for <insert_random_large_nubber_here> hours
It may just randomly flash.
The next suggestion is to buy a battery off ebay and replace it your self

Now there are something happening! I left the phone in the charger for 2 days and now the led light started to light up red.

Z2 tablet death

Hi I'm really hoping someone can help me. I received a Sony z2 tablet spg521. I was told it was new but it would not power on or charge, and the charge light would sometimes blink red. Well I got the fixed or so I thought by doing a soft reset and then pc companion...sounded simple but spent a couple days trying to be successful. Sometimes my computer would recognize it sometimes it wouldn't.... Any way I finally got it out the blue dont know what the difference was I was just happy it finally worked... I then fully charged...yadayada and used it flawlessly for about a week... It would turn on and off, battery held charge like its supposed to, everything seemed to work.....then I went to power off but hit the restart by mistake....no there is no power again and this time it will not do a soft reboot.....no light ever....computer will not recognize ever....I have been trying off and on for a few days.....among-est my research to try to correct it seems like this is very common....when i shut it off the battery was over 50%..so how can something work fine then just die like this??? Ive seen that sometimes with sony if you disconnect the battery and the reconnect this will work... does anyone know? does anyone have any advice before I take apart this cherry tablet to try the battery thing???
I would really appreciate any insight as I have fixed many of my own problems and for others from advice on this site. Have a wonderful day and thank you!!! :silly:
ok today i tried to use flash-tool that Ive read about on this site....when it asked to plug n device computer recognized it and red light came on, but flash-tool did not recognize it....torn between letting it set and seeing what happens or trying to get the flash-tool to work, I chose the flash-tool...bad mistake when I went to try to reconnect and see if the FT would see it..it was no longer recognized by the computer and no light but computer did say USB device not recognized and not installed correctly.....now I already have the right drives so now Im really confused..tried a couple more times with same results and then once again nothing...no light no soft reset no recognized at all by computer not even not recognize USB....so disappointing loved the tab but this is insane that sony does this as its not user error but sony error and they dont even man-up and try to make it like you dumb or something....will try again..when i calm...
reset the device by pressing power+volume(up or down) for several seconds. It seems like a toasted one, possibly caused by putting magnetic charger on wrong polarity.
Thank you yes Ive tried all kinds of resets I have found...I agree seems fried but I would not know how. I have not used a magnetic charger...only the regular sony one that came with it....
So last few days I have tried off and on again....now computer recognizes by making noise when connected and disconnected but does not show up...PCC does not recognize it.....flashtool says its connected in log but when it asks for it to be plugged in it never leaves the screen telling you how to connect....when I try to connect the charge light comes on for about 4-5 secs then turns off....still no vibrate when try to reset still no light when plugged to a charger.....I want to get another one but I am scared this will happen again....gonna chuck this one as if time is money then I have well exceed the worth in time... I only got this because some time ago a sony z1 came my way and I so love it...i recently upgraded to z3.....i have a lg pad but screen got broke so I got the sony tab....maybe Ill just fix the lg

Mine is kinda toasted and this is how it works. Whenever I have a problem, I have to reset by pressing power + volume up, as soon as I hear three vibrations, I turn it on by pressing power button. Otherwise this tablet will just repeat sony logo and no boot. If you have bought one "NEW" make sure to return or replace it. If you want to enter fastboot mode, repeat the resetting routine and pressing power button to turn on, but also right after that or even simultaneously press volume up to enter fastboot mode with usb cable inserted, or volume down to enter flash mode. either way, your unit is toasted and sony sucks.
Well, I have the same problem, and isn't fun. Just very extreme rare cases it turns on the screen charging the battery, but doesn't turn on sadly
I did a happy boot today after 3-4 months off with several times trying turn it on, and did all the tricks from all treats about SOD
Last weekend I did a full charge from deep red to green light and battery animation on screen at start, but no luck.
I put it back in the box
This weekend I got some visitors, one of them asked about the tab, told him it didn't work and showed to him
Pressed the power button and to my WERY BIG surprise, it vibrate and turned on as nothing was wrong
The battery was only 54% after one week off. it received a update (264) and I installed as normal, turned off and on again as normal and happy I was

Interesting Problem about my old Z2

Hello ,
I have a problem with my Z2 and I'm almost go crazy.
I dropped my Z2 but it was really soft and there is no damage. But phone doesn't work.
I put to charge and open phone see Sony name and see total charge and charging then close.
I push open button and no answer. I push hard reset ( open button and volume ) no answer.
I tried red button and when It is not in charge this button not work but if it is in charge then phone vibrate , see Sony logo , charge and then close again.
I open phone to see if there is no seen damage .
I opened sony compaion and made recovery , it saw phone and made recovery but same problem.
I need some help about this situation.
Thank you.
Hi,
An energy related problem, or the display cable may be loose. When I changed the screen of the phone a year ago, I encountered such an error. I worked for 3 days; but in the end it worked. I don't remember exactly how I did it right now. I looked at many web sites related to the motherboard. It's pretty annoying and challenging.
Bye.

It seems the flat cable is broken that connects to power and volume buttons.
You can check it under the battery and see if it's cut at the edge of the frame.

The red button is for force shutting down the phone. You only see sony logo then charging on screen only if you plug the charger. Try fastboot to turn on your device by writing this command:
fastboot reboot
I assumed you know how to enter fastboot.
