[Q] My Phone Charges, But Won't Turn On!

I just got a Sony XPeria Play from Ebay, and it doesnt turn on, ive charged it, but it doesnt vibrate or anything. But it does charge perfectly fine. Please could I have some tips? PC Companion won't help and I have taken the battery out and put it back in countless times.I also need some help with fast booting my phone

How can you tell it's charging?
Are you using USB to computer or USB to wall?

I can tell its charging because the screen goes to the charging icon, and I'm using usb to computer.

If you hold the search button while its off and conect the USB to your PC does the power button light turn blue? If so you can try flashing back to stock rom.
Or if you hold the back button and connect does it turn green?

Yeah it does turn blue, but the power button doesn't respond to me pressing it...

remove the usb and make sure everthing is off, now remove the lid of the phone and press the power button. Remember you have to leave it press a couple of seconds

I've got a feeling the power button is stuffed... It still won't do anything when I hold the power button

i would also think is the power button, cause if you hold the search button and plug the phone while it of and the led on the power button turns blue, and if you hold the back button instead and it goes green, i would say that the power button is definitively the problem

Ok..don't press the power button if you're trying to put it into flash or fastboot mode. It sounds like it's one of two things: 1. the button itself is not making contact OR part of the board is busted. Either way, if you have flashtool then hold back and plug it in the usb, flash the stock ftf and flashtool will boot your phone for you.

I hope its the former! Also when I turn on flashtool, it says I need drivers, where do I get them from? Sorry for my nooby questions.
EDIT: Found the driver installation file, now I just need a stock ftf

It's ok mate don't worry, it's not being nooby
Here is the link for those drivers:
https://rapidshare.com/files/1146432065/Flashtool-drivers.exe
Install it fully, so once you open it click next and tick all the boxes. I know some are useless but just incase select all. Thats what I did It will take a bit of time I know and messages keep poping up and just go along with and it will eventually finnish. I had this problem too.
You can find this driver installation file in the directory of flashtool aswell.
It should be in -> C:\Flashtool\drivers or something like that.
Good luck

Ok so I need a stock ftf file...

Mybe u should jst try reboot using command prompt 1st. Jst to be sure that is related to the power button or not. Install all driver. Mke sure the phne is off, hold the search button n connect to the pc n see light turn blue. After that open command prompt n type "fastboot reboot". If it reboot then u'll know its the power button related.
Thanks vokal1992

Do this:
1.- Open flashtool
2.- Hold the search button on your phone
3.- Connect usb cable while holding the search button
4.- In flash tool press the lightning icon
5.- Select fastboot mode
6.- Select Reboot in system
7.- Enojoy

Hmm, now I'm thinking it's a broken battery, because it gives up on me as soon as I unplug...

Unplug it after it reboots

It reboots into the charging thing and when I unplug it, it dies.

in flash tool, does it say connected in fastboot mode?

U need to enable the usb debugging to be able to reboot using flashtool. Mybe the easiest way is to flash another stock .ftf.
Thanks vokal1992

well, if you need to flash ftf heres a list of them:

[Q] Boot into fastboot?

I maybe missing something simple entirely, but after a lot of goolging I haven't found any answers. I'm following the guide on unlocking the bootloader for my phone with fastboot: xperiagamer.com/Beginners-Guides/unlock-the-bootloader-ramge[dot]html (cant post links yet) How ever I am unable to get my phone to boot into fastboot mode. Removing the battery and holding down any one of the following keys, back, menu vol down, shows my phone as "S1Boot Download" in control panel. And fastboot.exe does not find the device at all.
How do i get my phone to boot to "S1Boot Fastboot"?
Is there a different button I'm supposed to be pressing?
Is there some setting I'm missing?
Is there something I need to install before hand?
Phone is xperia play SO-01D.

You're not supposed to remove the battery to get into fastboot... You just power off the phone then hold down the search button as you plug it into the PC, not letting go of search until the power button turns blue

I tried :
*holding the power until given option to turn off.
*holding down search button
*while still holding down search button, plugs in usb cable
-Sony Ericson Logo Appears
-Phone goes into recharge mode
-Power button is red.
I tried this with home button and vol up button. Same thing. I was removing the battery before each try to make sure that the phone was completely powered off.
I tried using the adb on the command line"
adb reboot fastboot
and my phone just booted up normally. If it's a NTT docomo phone then is it possible that fastboot has been disabled by the carrier?

No idea if it's disabled by carrier, but it doesn't sound good

Not sure if this applies but, with the R800X and R800AT, you must have an unlocked bootloader before you can boot into fastboot....
Then to enter Fastboot you must power off the phone, press and hold the 'search' button, and attach to computer USB port.

Try installing driver on flashtool maybe.

Calm dowm man, i already did that **** once kkkkkk
Simple: Hold down the reset buton till your cellphone vibrate 3 times (That hide one beside your SD Card). That'll turn it off. So hold down your Volume ( - ) button and plug your USB, now you are in flash mode.
Open Flash Tools and flash a Stock ROM (Recommended) or Stock Kernel, That's it!

Sorry for bumping this thread, but I got exactly the same problem described by OP. But I simply can't get into the flashmode.
When I hold the volume (-) button and plug the cable at the phone, I got nothing more than the Windows USB sound and a red led of death on my ZL (C6503).
What I've already did:
1) Pressed the "Off" button beside the SD card slot a lot of times (holding it for a few seconds of course) before trying to get into the flashmode;
2) Tried SUS, PC Companion and Flashtool but couldn't get the flashmode or detected by any of them;
3) Keep it charging for more than 12 hours and all I got is this red led of Death!
Any help is welcome.
Cheers.
Edit:
Got the flashmode holding at the following way.
1) Pressed the "off" button beside the SD card slot for a few seconds and instead the 3 vibrations the red led blinked 3 times;
2) Hold the volume (-) button, connected the USB cable and keep holding for a lot of seconds, you will hear the Windows USB sound disconnecting and connecting a few times, wait until Flashtool recognize it and start flashing.

EMERGENCY Brick!

hi,
any help is hugely appreciated.
I wiped my phone in recovery with the option to wipe for new custom rom, this worked fine. when i went to install custom rom it failed and then turned itself off. now the phone just gets stuck at the Sony logo. the only way i can turn it off is via the red button in the sim slot.
I am unable to connect to the computer at all, no fastboot. I'm also unable to boot into recovery to restore.
Please help. Hope i haven't ****ed it up beyond fixing
Thanks

Flash a stock ftf with flashtool (in flashmode). You should definitely get into flashmode and fastboot, otherwise there is a problem with your computer.

Funny, I didn't even know there was a red button Holding Volume Up + Power for a few seconds always worked for me, no matter in which state the phone was.

Hi all,
I've exactely the same problem !!!
My phone stuck to Sony logo, and not reconyze on my 3 PC.... before that, usb connexion work fine on all PC, but now.... nothing
I've just POWER + and VOL+ (its power off the phone), i've no led color light
I've try flashboot, but not detect my phone
i've try to install :
flashtool-0.9.16.1-windows (not detected)
Flashtool-drivers-1.5-20140318 (my computer doesnt not see my phone)
Xperia_Z1_Compact_driver (my computer doesnt not see my phone too)
I can't go into Flashmode...
When i power off my Z1c, and i plug usb + (vol+) nothing appear...stuck Sony logo...
I'm lost... I need your help XDA members ! just U can help me
PS : the red button is in the SIM slot, but i think is same POWER + (VOL+).... its power off the phone

Because you're doing it wrong. Vol+ enters fastboot mode, you have to press Vol- to enter flashmode. Then use Flashtool to restore the firmware.

Sorry it's a mistake....
I've try both (vol+ and USB) and (vol- and USB).... but no sound (device not detected), in device manager nothing appear too.
I've make a fresh install of windows 7 x64 on another PC.
I finaly working to boot (2-3 times) with Vol- + USB cable, but stay in sony logo and Flashtool whait for device...
Please i need u're help beacause i'm really lost (usualy i flash many phone S4, Mediatek, phones, etc...) but now i dont find solution

My problem come from the original cable
All this because of the USB cable does not work ... CRAZY !
This USB cable is new and original sony... just 2 Weeks
I solved my problem with new one

That's unfortunate, good you found the issue.

xperia m5 dual (e5663) not starting. No response from device.

i tried to flash a generic lollipop firmware on my device using flashtool 0.9.21.0. I think i forgot to select wipe out sections. the flashtool log showed no errors. but when i disconnected the usb cable, red notification light kept flashig all the time. no response when pressed power button or combinations of power and volume buttons.
when i press the force power off button (beside sd card tray) and press volume down or up key and connect to computer, then sound is coming from the computer but nothing displayed in the device manager and not recognised by flashtool or xperia companion.
also no responce for charging. Is the device hard bricked? If yes, is there a way to recover?

Same here
I stuck too downgrading phone. Anyone please help out
