Boot Loop - How to turn off the phone?

I tried to unlock bootloader and got a boot loop.
Then i flashed the 343 FTF but it continue and now i dont have recovery to shut down the phone.
I think the battery will go 0% soon.
how can i at least shut the phone down? pls..
Sry to create a Thread but i dont have much time to search more :/
EDIT:
I finally got the phone to start, so i'll tell the "history" here to people that get the same problem as me, and ask some question before do anything wrong again.
History:
1- I was on .343, rooted, bootloader locked. Decided to install the 1.253 rooted version with dual recovery. Everything was fine, working great.
2- Then i passed to unlock the bootloader. Followed that thread... everything seemed normal again... disconnected the phone and powered it up.
3- The boot loop started. Got the sony logo, the lights flowing, and restarted... again, again, again
4- I entered TWRP tried to do a factory reset, got a error message... can remember what, but something about mounting...
5- Shut down the phone using TWRP. Opened flashtool and flashed the .343 TFT, Everything ok again, unpluged the phone and started it. (Didnt choose to wipe data and cache).
6- The phone boot loop again. That time without recovery. I got desperate and posted that topic.
7- Finally got the phone to shut down.(thanks boyob32). power button+volume up until it vibrates 3 times.
Basically is that.
SOLUTION:
Searching more calmly i found that thread. Used the Flahstool again (that time wipping data and cache).
The phone finally started up!
Now some question to not make myself a fool again.
1- What could i made wrong?
2- I'm a little scared to try to unlock bootloader again... Since i got no error when doing it first time, is it already unlocked?
3- when i was using flashtool with the phone in bootloop got some errors messagens regarding drives. Before that everything was OK. Should i install them all over again?
4- Can i unlock the bootloader before update to .253?
thanks again. you guys are great!
PS: I can't edit the topic title, sry for that.

Hold the power button and volume up together, after a while it will switch off.

[Q] Xperia Z Boostall/System Wipe stuck on SONY logo.

Hi i have searched for the past week and tried numerous things to try and fix my Xperia Z. From the 'Disaster recovery' thread for Z/Z1 and on...
what has happened is when i had tried to install the Xperia Z1 Social Camera through flashing (wiped cache/dalvik before and after)
that my camera app suddenly displayed a message about the camera not being avaible or present (even thought it worked previously to flashing)
after finding this i (silly enough:silly though flashing system would recover it but instead i seem to have Wiped it, and now im stuck at the sony boot logo. If i hold Power+Vol Up i get one vibration and then another three if held for longer.
my computer doesn't seem to find the Xperia when its in its dock (cant use Micro usb/charge port typically broke/loose) so doesn't seem to accept a restart +vol up to get fastboot or any other mode. it just boots back to SONY + Red LED
im going to get the charge port fixed or re solder it myself in hope it will allow a fastboot/ allow me to flash a FTF :fingers-crossed:, But does anyone have any other advice i could try using my dock to resurrect my Part-Dead inside Xperia z.

Emergency!

My fone has all the symptom of soft-brick but i think its hard-bricked I need assist from Pro immediately
-> cause: yesterday i wanted to install new CM12 on my Xperia V. I wiped out system partition, done factory reset, davik cache, and then ....... i fell asleep. i turn off my fone and thought that i will finish it today morning. But when i woke up, i realized that i have done the most stupid thing in my life - > i forgot to install the rom :cyclops:
->consequences: Now when i turn on my fone, a Sony logo appear, but that''s all, next is a totally black screen. I try to get into recovery mode but a blue light blinkering a few second & then it completaly black again. I try to connect to Flashtool but neither flashmode nor bootmode working on my fone. :angel:
What should i do now ????? love affair between me and Sony has come to the end ??????
poor me !!!!!!!!

Try to pull out the battery, wait 30 sec. and then insert it again. Open Flashtool, connect your phone in fastboot mode and flash a boot.img form WhiteNeo's Homebuild (as you were planning to go for CM12).
If you cant enter fastboot mode, then you have a driver problem. Search in the forum for Fastboot Driver installation. You'll find the solution.
And I can confirm, it's not hard-brick

XZ in continious bootloop, no matter what i flash/do

Hi guys,
Device info:
Model C6603, Unlocked bootloader
So i have the following problem, my device is in a bootloop and i can't figure out what the exact issue is. I'm out of options at least.
First a little background on how it came to be: (scroll down for short overview)
Before official lolipop came out I've been on CM12.1 for a few months, cm-12-20141221-INFECTED-yuga to be exact. When official lolipop came out I installed C6603_10.6.A.0.454_Customized_HK-Rooted+Xposed Modules for LB following the instructions, although i see the thread has been modified (name, updated etc.) the instructions are the same. I did not install Xposed yet, because i wanted to try stock+root first.
After a few weeks of normal use, i used google maps navigation. This worked fine but when i arrived at my destination and picked up my phone closed google maps app but then my phone crashed. It rebooted to the point where i had to enter my pincode, but every time i was entering my pin it crashed and after a few tries it dind't even got to the lock screen but only showed the sony logo and rebooted(bootloop). I noticed my device was getting hot and left it alone for a few minutes, after that i started my phone again and was able to use my phone again. Until I started google maps again for the way back and enabled gps it crashed again, the same thing happened the phone would reboot when entering my pin, the phone wasn't hot this time. I left the phone alone till i got home, put it on the charger and the next day my phone worked fine again.
A few days later i was outside in the sun whatsapping, when the same happened my phone crashed and rebooted when entering the pin or slightly after. The phone was feeling hot, also because it was exposed to the sun for a while, in TWRP recovery it showed temperatures around 70 degrees celsius (i don't know if this is too hot?). After i had left the device alone for a while and try to boot it up it got stuck in a bootloop (sony logo), after a night of charging it got to the point of entering the pin code again but crashed and got stuck in a bootloop again (sony logo). And since then i'm not able to get rid of this bootloop. However i could still get into recovery (TWRP).
First i tried to reinstall the rom, factory reset and flash via recovery: C6603_10.6.A.0.454_Customized_HK-Rooted+Xposed Modules for LB
This worked, and the device booted up but after a while it crashed and got stuck in a bootloop again (sony logo).
So all summed up:
cm-12-20141221-INFECTED-yuga
>> C6603_10.6.A.0.454_Customized_HK-Rooted+Xposed Modules for LB
>> Google maps navigation >> overheated >> bootloop (sony logo) >> charging night >> working >> whatsapping in bright sun >> overheating >> continuous bootloop (sony logo)
What i have tried:
- Tried booting without sim card, withoud sd but doesn't work
- Flash same rom via recovery C6603_10.6.A.0.454_Customized_HK-Rooted+Xposed Modules for LB : Worked once, but then crashed and went back in bootloop, now when i flash this only Bootloop (sony logo)
- Flash updated version of http://forum.xda-developers.com/xperia-z/help/lollipop-5-0-2-10-6-0-454-pre-rooted-t3116205 via recovery : Bootloop (sony logo)
- Flash kernel via fastboot http://forum.xda-developers.com/xperia-z/development/kernel-unlocked-bootloaders-t3114234 : Only recovery works
- Flash stock kernel via fastboot: boot (sony logo) one time then turns off
- Flash stock lolipop (with and without bootloader unlocked) via latest Flashtool : Bootloop (sony logo)
- Flash stock lolipop via xperifirm (C6603_10.6.A.0.454_KPN Mobile NL) xperia (with and without bootloader unlocked) via latest Flashtool : Bootloop (sony logo)
- Flash stock kitkat (with and without bootloader unlocked) via Flashtool: Bootloop (sony logo)
- Relock bootloader and Sony PC companion restore latest firmware : Bootloop (sony logo)
- Restoring serveral backups from TRWP and Phillz touch but they all result in the same bootloop, while at the time the backups were made there were no problems.
I'm pretty much out of options and begin to thinking something was damaged when the device overheated or a bad partion of a kernel is still stuck in the devices kernel.
Does anyone had the same issue, if so how to fix it? Or another option i could try, maybe someone spotted anything i did wrong?
Current state:
Locked bootloader, stock lolipop 10.6.A.0.454 flashed via Sony PC Companion recovery
Boots into setup, after a few reboots I completed the setup. But still randomly reboots when trying to use some apps or in general leaving it in standby for a while (might be due instability).
Thanks in advantage,
Jonathan

So the only things that you do that do not result in a bootloop are flashing a kernel. Try flashing a Stock kernel with Flashtool --> open flashtool >choose the flash button at the top left > flashmode > choose the firmware > check cache and data above and below check Only Kernel. Post result here...
Good luck

Don't do this. It will wipe your data and flash everything but the kernel, therefore losing root etc.
If you want to flash a stock kernel, you must leave everything in the "Wipe" section unchecked, and check everything but "Kernel" in the "Exclude" section.
I don't think this will help anyway, being that you're already on a stock firmware flashed via Flashtool.

Thanks for your fast reply, I think you meant: check everything but leave kernel unchecked (as kingvortex replied at the time of writing)? Since it is an 'Exclude' list. I flashed stock kernel, it shows the Sony logo and then shuts down. I used stock lolipop kernel from 'C6603_10.6.A.0.454_KPN' Mobile NL, and i also tried 'C6603_10.6.A.0.454_Customized CE1'. both have the same result.
I've got the most "life" after i restored my phone with pc companion to 10.6.A.0.454. Then, after being charged via the wall charger for a while, it boots up normally and goes into setup, since it is a complete restore. But crashed around the setup screen for wifi. The other options i tried do not come any further than showing the Sony logo, this stock one shows Sony logo >> android logo >> boot animation + sound.

I'm thinking it might be a case of a dead battery or battery controller of some sort. Because the phone only boots up normally, with stock android .454, when the phone is connected to the wall charger. Whenever i pull out the cable the phone crashes and reboots, also when not connected to the charger it gets stuck in a bootloop. However when the phone is connected to a charger and working for a while it still randomly crashes when using the device, sometimes these moments are suspicious because it sometimes reboots when enabling gps, wifi, mobile data or when starting an app, phone call or synchronizing accounts for instance. On a side note sometimes the battery percentage drops about 6-9 percent when rebooted one time or when crashed, also when i connect my phone to the charger the status led is red but when done showing the sony logo and when charging it turns green (or yellow, depends on battery percentage). This is why i think something internal is not working properly whether it is the battery or the battery controller, i don't know.
I still find it weird that the phone was in perfect condition before flashing .454 stock lolipop, it might be due to overheating that some components where damaged. At least i'm guessing this is the case because i know no other reason why it would show such behavior. Is there someone who has experienced something like this or another solution i might try?

In the mean time i bought a Z3, my XZ is definitely dead now after the battery has discharged and i can't charge it because it's constantly rebooting. However flashmode and fastboot are still working. Thanks for the replies. I might repair my XZ if i can get my hands on a cheap (broken) second hand and replace the internals, but i'll see.

Hi, i have the same problem... i cant charge and the constantly rebooting... and in my case also... when i try to flash any ROM, flashtool and Fastboot are stuck for 1 hour when try to flash system.sin (system.img)
i stop flashing after 1 hour... not sure if could finish after 2 hours :/
Cant use PC Companion because dont have charge in the phone (locked bootloader)
Any suggestion?

need help, regarding xperia T lt30p cant turn on

hello everyone!
i have a few questions. and i have done my research yet i still find no solutions so i will ask here
this is my story...
-root,unlock bootloader,flash cm12 android 5.0.1, ran cm recovery
-running fine for around 2 weeks.
-in those 2 weeks there has been times where phone drained to 0 its battery, then charged it then it was fine
-suddenly one day. charged it after it drained completely. then wont turn on.would boot up to 'sony' screen then repeatedly reboot and do the same thing again.
-could enter recovery, but when trying to reflash rom, phone would reenter boot loop
-have tried charging for days.
-have tried removing battery, same thing
-then used flashtool, relocked bootloader, reflashed stock firware, now cant get into recovery, flash successful, yet phone still cant turn on pass sony screen.
is it a battery problem?

just to add, ever since the first time it started having this problem, i could never get the phone to turn on at all without plugging it in .

Hi Jetdin
had the same problem with my XT a year ago, when a powerbank somehow "nuked" the battery-logic... After that, I had the pleasure to know what a deep-discharge feels like :-/
To revive my XT, I had to replace the Firmware... I did it this way, maybe you can try a "factory reset", maybe it already works out for you...
1. loading it (turned off) 24h with original recharger (don't try to turn it on)
(1a - if you can reboot it to save apps, data, files - do it)
2. reboot into TWRP - and do a factory reset
...and try your XT; with luck, this already solved your problem... if not:
3. get the new image of your choice - i downloaded whiteneos 12.1 - works like a charm... and copy it to an sd-card
4. after (re)loading the XT - boot into TWRP - and install the new image...
...reboot and hope this solved the problem...
Good luck!!
Edit:
that it only stops at the sony-logo sounds like "operating system not working" - maybe a "higher" OS-version will do the trick?

Thanks for the reply theunlucky.
I have tried most of those.
The cm12 was on Android 5.0.1
The stock firmware for the Xperia T only goes up to JB huhu

you cant get pass the sony logo?
unlock your bootloader again
1. download whiteneos cm
2. extract the boot.img and flash it via fastbootmode
3. reboot
4. if you see a led hit vol + ( or vol - ) several times until the led color changes
5. now you should be in recovery... try to flash cm12.1 from whiteneo and reboot
