[Q] Bricked SP

Hi everyone.
My SP doesn't want to turn on anymore for a unknown reason. When plugging it to the pc\charger the red led appears and then disappears. Non of the tips (power + vol. plus, power + vol. minus) doesn't work.
Please, help. If your suggestion will help, I'll pay you.

put it into charger and leave it charging for like 1-2 hours, also remove sim and sd card

It was on the charger all night long (with no sim and sd) and nothing. But now there is no red light.

Take it back to the shop

How did this happen?? Try this pull out the back panel and press the reset button with a pin and hold the power button and see what happens
Also you may try this install Sony PC companion This will install all the correct drivers for the phone then take usb cord Holding volume Down And Plug it to the phone. If all goes well the led at the bottom should glow green

I had a similar issue and after 4 days of trying all what i could find out in XDA for bricked Xperia phones my SP is back alive.
For me it happened during flashing (with Flashtool 0.9.11) the stock firmware .257 with to less battery power.
Short Info to my phone when it happened
Sony Xperia SP C5303
Kernel: Dooms v01 (i do not think that this was the problem!)
Bootloader: unlocked
Stock firmware from C5302 version .284
System: deodexed and rooted
When i say flashing i did it always with flashtool because PC Companion and SUS did not recognize my phone at all (with locked bootloader).
My SP was behaving as following.
- When i put the wall charger on the phone nothing happened no lights nothing same if plugged in to the computer.
- If i pressed the power button unconnected the LED flashed red 3 times all the time,
after a while nothing happened anymore (which gave me the indication that the battery is completely empty)
- If i pressed the power button continuous during charging (wall/computer) the red light turned on until i released the power button.
When pressing the Power button long enough during i was connected to the computer the green light turned on and i was in flash mode.
But only for maximum 2 min. This was enough to flash all firmware parts except the system.sin (at ~80 % phone disconnected).
And this was the problem my SP stayed dead.
Before someone asks, standard connecting while pressing the volume down for flash mode or volume up for fastboot mode didn't work.
Now i tryed all:
- Left the phone on the wall charger without doing anything -> nothing
- Left the phone on the computer without doing anything -> nothing
- Left the phone on the wall charger/computer while pressing the power button continuous (did it with a tape) -> nothing except that it went in flash mode and red light again all the time
Now my last try (i was reading this in an X10 thread):
I plugged the phone more than 7 hours to the computer while pressing the volume down button continuously (again taped).
Next morning it first looked like that this also did not work.
But as i disconnected the phone from the computer and plugged in again the red light stayed on.
Ok give it a try i thought and i put the phone to my wall charger for 1 hour or so also here the red light was glowing continuous now.
And yeah i could connect the phone to the computer in the normal way volume down than usb and i was in flash mode.
I was now able to flash the complete stock firmware. After again putting the phone to the wall charger for 1 hour the system was booting :victory: .
And now i saw the problem battery charge in status bar showed 1 % but the firmware start up check showed 55 % .
I remember that i did wipe the battery stats in recovery before all that happened.
No idea if this caused the problem.
However i could now charge my phone and it is still alive relocked and on stock.
Hope this helped and good luck.

To prevent other people from this bad situation i tried to remember exactly what caused the drain of the battery to 0%.
Battery was on 25% at start. (I know this was stupid, i was too impatient as dooms v16 and cwm for locked bootloaders were released :silly
1.I started with trying to update my mobile to stock with PC Companion and SUS,
without thinking about that this will not work with unlocked bootloader. -> first battery drain
2. Got stock FTF for .257 (c5303) and wanted to flash it which did not work got errors always.
My SP was connected flashmode on my notebook a long time while i was trying to fix that (reading XDA, driver config etc).
Several times tried to flash without success.
-> drain, drain and more battery drain not thinking about that i started with only 25%.
3. Gave up on my notebook and connected my phone to the Desktop PC (here the config was ok i knew that from flashing before on that computer).
Meanwhile i assume that my battery was already close to completely empty.
As the flash of the FTF (all parts) started my phone turned off and was "dead", i do not remember on which sin it turned off.
The whole time 1. 2. 3. i never booted i always stayed disconnected or in flashmode.
And than the mess began which i posted in my previous post.

So my SP is officially dead. Need to replace to motherboard.

You should keep pressing that button till your phone's screen goes black and vibrates 3 times if it doesn't do that then either the mobo is dead or the button is broken!
well... that's why I kinda hate sony why not do like most makes do (Like iphone, htc, samsung etc just long press the power button to reset the damn thing! It gets really annoying to keep pulling my case and back cover off and then putting a pencil in that tiny hole in public :/)

watch?v=daNue2RsUbY ( video of my phone with the fading logo )
had the same problem with mines ( i manage to record this fading logo part )
hours later after the record my phone won't even turn on and it only shows that red light popping up when i press the power button
i brought it to sony's service center here and they replaced the battery, that managed to fix it <3

For me pressing the back off button and volume + button force it to fastboot mode. From there just flash a kernel and it is fixed.

which kernel???

maybe try holding down on vol key and plug into USB port of computer
something similar happened to me during my initial root process and i'm pretty sure that's what fixed it
or hold down + power until 3 vibes
then after hold power until boot up

I can not get it, do you have Xperia X or Xperia Z ?????
If former, I would advise you to address to the appropriate Xperia X forum
If latter, I would suggest to charge XZ in DK26 dock overnight and look if it comes to the life on the morning. (USB charging is vicious circle: it sends the signal to phone to boot as soon as the battery gets a bit charge, however this charge is not sufficient to boot it completely... so circle continues )

Disconnect from charger. Hold volume up for 10 seconds I think or longer(up to the 3 vibrates). What happens?
open flashtool and connect your phone while holding volume down. what happens?
Does the FlashTool say something?

Hold powerbutton + volume up till it vibrates 3 times indicated your phone is shutdown. Then charged your phone using wall socket. And be patient.
Its look like your battery is totally flat.

But i have a similar problem to the stated one. After flashing the new leaked 4.3 Rom from DoomLord my phone ran just fine for nearly a week. Yesterday i inserted a new sd card and wanted to format it in recovery. But then after formating sdcard1 my phone totally freezed. However i rebooted it from recovery. No led when i plug in. I tried every combination of buttons presses (also volume up + power button which does normaly the trick). I even opened the phone and unplugged battery for 2-3 min, still nothing. Do you guys have any idea what i else can do, or is my phone simply broken?

charage the phone for 24 hrs or overnight and try flashing the stock rom via flashtool. if it did not work with vol down button+power try this method 2
try to do a hard reset; (while NOT connected via usb or something) hold power+vol up, it will vibrate 1 time, and then 3 times quick. After that try to connect the usb (NOT while pressing any buttons) and press vol down+power
That should connect it into flashmode.

Thank you for your reply.
Unfortunately this didn't work. However after letting the phone charging for a while i got a red LED. Which disappears every 5 min and comes again after another 5. When i disconnect phone from charger and connect to my notebook nothing happens. I mean I press vol down + power there is nothing the phone doesn't react. If i try i hard reset. The red LED is blinking and the phone doesn't vibrate .

Ok, I disassembled the phone again. I removed battery and measured voltage seems to be fine. Besides battery life was OK when it worked (OK compared to my SXplay ). Additionally i tried the battery trick from this post http://forum.xda-developers.com/showthread.php?t=2449242. However the bahavior on charger is still the same 5min red LED 5min no LED at all. Excluding it is a driver problem I ran flashtool on my linux machine and tested both the windows and linux flash tool with my xperia Play which is correctly detected in flash mode.
Thanks guys for your hints upon now but I would be happy to get additonal ones. I'm not afraid of disassembling and getting my hands dirty.
I hope I will get this great phone running again since I've really started to love it :-/.

Same situation with CM 10.2
Hi there I'm in the same situation with my xperia V.
Bootlocker unlock and flashed 10.2.0 (latest stable rel) and gapp. No issue everything was working but huge battery drain due to Media Scanner, so I've reboot in recovery wipe the cache and format the external sd then reboot all from the recovery menu.....then the phone is dead.
now in change since more that 30 hours and get red light for some minutes that nothing at all....nothing pushing power, nothing pushing volume nothing at all.....if i connect without battery to the power red light blinks.
how is that possible???? at least recovery node should work...is that an HW problem? but how can i have created an HW problem with a wipe a format and a reboot????
Please help...

How much voltage is the battery? For that battery trick, are you sure, you did it correctly? Could you post some pictures? If you're sure, it's the battery, buy another one.

Ok i attached a picture. The measured voltage is 3.07 V between kathode and anode marked in red (of course I measured it when the battery was disconnected. Moreover you see the soldered connection to the back of the battery marked in green. I've already tried what I red in another post in this forum, where the guys there suggest to unplugg the battery and try to connect the phone in flash mode. This results in a blinking red LED :-/. No idea what else I can do

Charge the battery somewhere or buy new battery. 3.07V is not enough.

Battery Voltage
peetr_ is right, using GPS Essentials to measure my battery voltage at 12% charge (not the most accurate way I know) it's measuring at 3.611V

Yes, it's worth to try it. Just try to borrow it from someone, let it boot and try to use your battery again.

no way even changing the battery

xperia t now alive
hello guys I have a solution to this problem.and I guess you guys are lucky cause I experienced this problem also.you don't need to panic cause this will help.all you need to do is to get a new battery either online or in your domestic regions.if you wish to get it online go to aliexpress.com And it will be shipped to you no matter where you are on this earth.the reason is because the xperia t has been drained to the core and so it can't come on in other to flash in a kernel or image. When you've bought the battery you can actually fix it by yourself cause I'll Show you how.when you've fixed it then you flash in 4.3jb stock room in it and then your phone comes back alive like mine.IV actually used the phone for a month before that problem occurred but now say no more to that cause this thread will work 100%

[Q] Unable To Turn My Xperia Z On!

Hey guys, got an Xperia Z c6603, unlocked bootloader, flashed Paranoid Android and have been running fine ever since. However, last night while in use the phone just went black. I can't turn it on, when holding the power button I get the LED in the top right corner flashing red 3 times. It won't seem to take a charge either.
Things I've tried;
Power Button + Volume Up (No Response)
Power Button Holding (Red LED flashes 3 times)
Power Button + Volume Down (No Response)
Connecting to charger (sometimes the LED flashes red once for a moment and then turns off)
All the above combinations while plugging into charger (No Response)
Connecting to PC (Same as above and Windows won't detect it)
Trying to enter Flash mode and Fastboot mode (No Response)
Anything I can do to revive my Xperia Z? It seems to me like the battery is almost completely discharged. Already sick of returning to an iPhone after having a great eXperiance so far
Any attempt at help is appreciated!

Hmmm, I think something might be wrong with either your motherboard or the on/off button. I'm pretty sure it's not a battery related problem in terms of it being almost dead. I've got my XZ since Feb 28 2013 and my phone still survives for days.
I don't know how long you've got your phone, but it might be time for a repair center, since there isn't really much you can do. Especially since the phone isn't being recognized by Windows anymore.

I got a few red led blinks in the past but i fixed it after charging (just pluged the charged and booted fine)
Try to leave it on charger or wall charged for 1 day and see
