[Q] Xperia V (LT25i) not turning on - Sony Xperia T, TL, TX, V

hello,
My xperia V lt25i is not turning on. I just made a nandroid backup using CWM and rebooted the phone and this happened.
* when i pressed the power button(hold) to tun on - red led flashes twice a second or for 2 seconds like that and keeps on repeating
* when i released the power button - nothing happens, no display , no led, no vibration
* when i connected to wall charger - red led lights up immediately and it lit for 40-50 sec and went off and again after about 30 sec - 40 sec again it lights up , this repeats.
* tried for flashmode and fastboot - same thing happens as in the above mentioned point - led on /off and repeats this.
* i tried to connect the wall charger while holding the power button - now led lit for long time which means its on for about 3 mins and off for about 1.5 mins and it repeats.
* now connected to laptop with rubber band tied over the vol. down button and flash tool is waiting for device for flashing (kernel and partition only). it been already 30 mins but still no detection by flashtool
* pc device manager refresh when device led goes on but it is not showing any device.

My friend had somehow same problem on his Galaxy Note3, it was battery related. Try another battery

Xperia T shutdown.

So like 5 minutes ago I checked the phone and got no response. Pressed power, long-press, nothing happened.
I had like 30% battery left when I checked it last time. I connected to power, nothing happened.
Then I connected it to my laptop's usb and it showed "life signals". ~24% battery left so it wasn't dead.
This never happened so far since I got my phone last year in october.
I have the JB update but nothing else. I don't know what could've caused this.
Do a hard shutdown. (power+ vol. up till you get 3 sort vibrations)
Then try powering on again

Dont work for me (((
Currently, my phone fails to start over.
It was root (see my signature) it functioned very well, but when I tried to flash it with this rom ([ROM][4.1.2][T/TL] TuRdZzROM v2.0.6 - 9.1.A.0.489), the flash is ok , but when I reboot the phone, it will not boot anymore, no SONY logo, no vibration ....
When I plug it into USB connected to a power outlet, the green LED lights up and turns red after a few seconds, then the LED will turn off and becomes green, red, green, red ........ ..
When I press the power button, the red LED flashes 2 times and nothing, no vibration ....
When I launch Flashtool, the phone is not recognized or connect and déconect .....
When I press POWER + Vol.UP red LED blinks 2 times, stop and re Blink ....
What can I do???
Plug it in the wall charger until the led lights up green continuously.
This may take more than 24 hours. After that try turning it on

[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

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???

Did you left your phone whilst reinstalling any ROM or flashing anything?
I can suspect that you;ve bricked your device.
You can try to stick POWER BUTTON + VOL. rocker and leave it for entire night. I have read that some had fixed this issue by the way which I'm writing now, but I'm not sure if it will work to you.
You can even leave your phone connected to charger for some while.
If it will not work either - I have seen some where in this forum thread in which were specified how to unbrick XZ with disassemblying it

Xperia Z bricked issue

Hello, my xperia z bricked suddenly while I was gonna flash a stock rom with flashtool (I used flashtool many times before). I just turned off my phone and then prepared flashtool to flash stock rom (kitkat). When flashtool said to connect the phone in flashmode, I just press the volume down button (while turned off) and connect the phone with pc. But nothing happens then. Phone doesn't response. Pc/flashtool couldn't detect my phone and also my phone doesn't response. No led light, no vibrations (holding volume up+power button for 5/10 seconds), no led indicator while charging. Nothing. Just died suddenly :crying:
Then I dissembled my phone and disconnected the battery connector from motherboard. Then I connected it again and plugged my phone to wall charger and charge my phone (no led light appeared that time while charging, phone just heated up) around 20+ hours. After that I got a red led light whenever I plug my phone into pc or wall charger. But the red led turns off after around 30 seconds. From then, whenever I connect the phone to wall charger or pc, red led appears and after around 30/60 seconds, it disappears again. I don't understand what does that mean So,
1. is it hard bricked or soft bricked?
2. is there really any chance to fix that problem by myself? I unlocked bootloader so there is no chance that sony will fix that 'brick' phone.
Any help will be highly appreciated.
Thanks guys.
You can try s1tool to flash your Bootloader.... Search the forum, u can follow the tutorial.... There might be a hope

just try to have the usb cable conected to your pc and hold the power button and volume up till it makes a vibration ,and then hold volume down even if it does not vibrate it should still conect to flashtools .
