[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???

Dead z1 :(

It seems that my z1 has just given up on life.
I was checking my gmail and the phone switched off. It wouldn't switch on so I tried vol-up and power, it vibrated but did nothing.
Now absolutely nothing will make it show any signs of life, it seems to be completely dead which is weird. No LEDs or vibrations at all, so I guess I'll be returning it :crying:

Dude you ran out of battery. Try to recharge it.

That's odd... Well sent it to Sony.

Guess I'm gonna have to

Even mine was dead for sometime today
Even my phone gave me a shock today... Screen switched off and the phone was not responding.... had to reset it through the sim tray!

I get 3 vibrations when holding the reset button next to the SIM tray, but nothing else.

Strange. Vol down and power would reset the phone?

I had the same issue your having with my rooted Samsung s4. I couldn't get anything. Bought secondary battery... Son took into verizon came on briefly. My programming USB cable rusted out, had to buy a new jib. That didn't work. I just persevered, I found life when I put in the battery and started hitting the power button repeatedly, 15-20 times
Finally it would turn on, used the jib got it into download mode and flashed the ROM with odin again. Still had some issues so I did a reset then re flashed again, re rooted and started loading programs.
Still not sure if it was/is the power button or system change I made with exposed or other such toolت.
Also now using button savior as a preventative measure. As an added bonus I have 3 batteries and a stand alone battery charger.
Please update your thread as status changes. Hope you get it working.

"If someone helps, never forget to hit thanks ? "

my z1 2 hours ago had died, I solved by connecting it to flashtool with the volume down pressed. I have version .157

I would think faulty battery, had same issue with old s2

No idea what the problem could be, perhaps moisture got into the headphone jack or something and made its way into the phone.
As I said, when I help vol+ and power it would vibrate 3 times to indicate power off however it would show no signs of life when turning it on.
Flashtool wouldn't recognise it nor would PC Companion.
I sent it away to Sony to repair last week - it's currently still with the technician. I'll update the thread as the repair progresses to let you know the outcome! Hopefully it will be a manufacturing error and I won't have to pay for a repair.

I recognize this problem in a slightly different form.
When my battery is completely dead and I try to charge it and turn it on it won't. It gives me the same three vibrations. I let it charge on the fast charger the whole night. Nothing. (0% charge, light stays red all night long.)
Then I reset it (red dot next to SIMtray) (which does nothing, no vibrations) but it works if not connected to the charger (it only vibrates then)
After reset I try to charge it and it goes automatically on but when it goes on it stops charging after splash screen and turns off and stops charging.
Then it's just trial and error. Reset, no reset, manual turn on, turn off, reset with USB connected, without and eventually it charges and I can turn it on.
After that it works fine.

[Q] HTC One Charges but Won't Turn On

Hello guys,
A while ago, I was just doing stuff I normally do with my phone. I flashed a ROM and it rebooted normally. I then flashed a MOD using TWRP recovery. As usual, every MOD that uses Aroma Installer has a "Reboot device after install" option so I chose that and then **** happened.
Out of nowhere my One suddenly shuts off (The install was done so...)
I have tried the sensor under bright light trick and my phone does vibrate once but nothing actually happens. Just a black screen and stuff.
Sometimes it does go into this screen where it shows a battery icon with thunder bolt in the middle (Yes I know that is the charging screen. But, I also believe that it acts like a progress bar and it does not do THAT.)
Then again, it dies and it doesn't have the charging LED nor would it turn on.
Help is appreciated. I know basic and complicated android stuff but I can't do any of that if my phone is dead
Edit: When I press the power button for a few seconds, it vibrates but nothing happens. The screen is still off and the charging LED is not turning on as well.
Edit: Okay, when I do get it to charge, it shows that charging screen and when I unplug it, it freezes with the charge light on. The phone is also heating up so that does mean it's charging
Regards,
TAM

No. But I was able to drain the battery and once I plug it in using the original HTC wall charger (which is the one that I always use to charge it.) it charged but the charging LED is blinking (mut have drained it self good overnight) am I making progress or did I make it worse?

It's difficult to say at this point, Personally I would just leave it charge over night. Then try and power it on with Volume Down+Power while still connected to the charger. And it definatly doesn't show up in device manager, not even as Unknown Device or QHUSB_DLOAD? I find that a little odd.
But there are signs of life so I think a good charge may do the trick.

Yes. I did plug it into my laptop's usb ports last night when it still had charge (usb 3.0 if that helps) but it was neither recognized nor visible in the device manager. I hope! I am now charging my phone as we speak. I hope it's not dead too

Okay so...I installed HTC Sync and still nothing. It was not recognized and it's still not booting

Try Windows 7 USB 2.0
just htc Drivers
Try to go to Boot loader and flash firmware
if it show battery with charging sign it means Soft Brick or battery problem
if it showed nothing like no charging light or nothing on screen then its Hard Brick

Then it is probably a soft brick or a battery problem. Because when I got home I immidiately pluged it into the wall charger for it to charge and it charged showing the charging screen with a blinking LED. One more thing, if I press the power button for a few seconds it vibrates and then nothing happens. I am planning to leave it charging over night. Is that a good idea?

can I ask what your flashed before it did this ?
also crazy question, but have you tried holding down the power button till the lights on the bottom flash approx. 12-15 times ? this resets the device, Ive had to do this after many flashes of various things.

I was flashing a MOD then after the installation finished, it asked if I wanted to "reboot now" so I tapped yes then the phone died and it won't start anymore. Yeah but how long should I hold the button? Just to clarify, my phone only vibrates if I hold the power button for a long time. It just keeps vibrating and vibrating

until the lights stop flashing, usually about 12 or 15 times cant quite remember exactly how many times they flash but its quite a few.
I know you said you tried the bright light trick, but you should also try this trick whilst holding down the power button.

Umm...but the buttons don't light up when I press the power button for a long time.

It does this but when I unplug it, it freezes like that with the LED on.

Edit: When I plug it in the computer it doesn't show up (I think that's good because it's a sign telling me that maybe the phone just needs a long ass charge). Now I will be leaving my phone to charge over night and hope that it will boot up in the morning. The phone becomes hot too while it's charging.
Note: I also do not have access to RECOVERY, BOOTLOADER and FASTBOOT.

Okay so I plugged my phone into a laptop with USB 2.0 ports and it showed up in device manager as an "Unknown device". Not sure if it was caused by the phone showing the battery charging screen but anyway that happened. Is that a sign of life? What should I do about it?

[Q] My Xperia SP bricked, wont start

Hey guys,
I need your help!
My Sony Xperia SP (C5303) wont start. It crashed while I was using it. Display faded and afterwards I am not able to turn it on.
I searched a lot but havent found anything useful to my problem. I found these articles(well more, but those are the most comprehensive ones):
Article 1 on xda
Article 2 on sonymobile
I tried everything what was mentioned in those articles. Nothing helped. Honestly I am a bit rusty with toying with my phone. I have been in to it on collage, but last few years I settled with what I installed back then ( eXistenz Ultra 3.0.0 I guess or similar version)
When I am trying to charge it red light is on. After a while (15 mins or so) red light disappear. When the phone is at least a bit charged and I try to turn it on it flashes red three times (not every time).
When I plug it in the computer while having Flashtool open it goes like this:
22/055/2015 13:55:27 - INFO - Device connected with USB debugging off
22/055/2015 13:55:27 - INFO - For 2011 devices line, be sure you are not in MTP mode
22/055/2015 13:55:28 - INFO - Device disconnected
22/055/2015 13:55:32 - INFO - Selected null
22/055/2015 13:55:32 - INFO - Flash canceled
I guess that is all I know now about the problem.
Please help
PS: I tried the turn off button in the back ( even holding it for like a minute )

From the above info i can only make out that your device is unable to connect to flashtool. Use USB cable of good quality.
You also try reinstalling flashtool

I installed Flashtool v 0.9.18.5, used three different USB cables (including sony original) still the same log. I do not think problem is in this
Can I offer some more specific information? Honestly I do not how else describe my fatal problem

Seems that your battery is completely discharged or you have drivers problem
Here you are step by step:
1- Connect your phone to wall socket and let it charge for 1 or 2 hours
2- After that force shutdown by pressing back reset button till vibrate three times.. Do not turn on the phone
3- Uninstall flashtool and any xperia flashing tools or drivers
4- Download and install PC companion from here:
http://www-support-downloads.sonymo...nloads/PC Companion/Sony PC Companion_Web.exe
5- Open PC Companion program and connect your phone to PC via USB cable while pressing your phone Volume down key
(You should hear windows new hardware plugged sound and your phone led will light with green)
6- follow PCC wizard to repair your phone

Hey, thanks for advice, OsGhaly.
Sadly I already did this - charged my phone from wall socket - pressed the back reset button (hold it) - nothing..no vibrations, nothing
Update: I have this problem for 2 weeks ( using another phone meanwhile), now I tried just for sake to charge it again (I tried everything 14 days ago ) after like 30 minutes it actually kinda turned on - it booted into the screen with charging battery. I was like whooah So I tried to turn it on. During loading graphics got messy again and screen blurred off. An everything is as it was. Broken.
Seems to me it somehow restarted over that 14 days (battery drained ?) and thanks to the fact that battery was depleted it kinda turned on. I guess it was a mistake to try turn it on immediately. I should have tried to reinstall the phone in that battery charging screen I guess. ¨So maybe I should just wait few days to let the battery drain again a try this ? Do not know :-/
But again what u have described I tried 14 days ago, did not work sadly.

Update: I have this problem for 2 weeks ( using another phone meanwhile), now I tried just for sake to charge it again (I tried everything 14 days ago ) after like 30 minutes it actually kinda turned on - it booted into the screen with charging battery. I was like whooah So I tried to turn it on. During loading graphics got messy again and screen blurred off. An everything is as it was. Broken.
Seems to me it somehow restarted over that 14 days (battery drained ?) and thanks to the fact that battery was depleted it kinda turned on. I guess it was a mistake to try turn it on immediately. I should have tried to reinstall the phone in that battery charging screen I guess. ¨So maybe I should just wait few days to let the battery drain again a try this ? Do not know :-/
But again what u have described I tried 14 days ago, did not work sadly.

Why u want to wait? U can simple press and hold the reset button for 8 sec or so till it makes 3 vibrations consecutively. After that charge your phone for 1h and then without booting it flash stock ftf via flashtool

When you unplug the back of the phone you have a yellow power off.
Plug your usb, push the off and power + and release when blue led appeare.
If don't work push long time (1mn) the off and retry

Nothing.
Rom is eXistenz 3.0.0
here is the thread with that rom:

I am not actually sure which kernel it is, since in the info it says something else than in installation guide. So please check for yourself because I could give you a wrong information

Still no progress. Please help

eXistenZ uses stock kernel. I think you should try flashing your SP through some other PC.
Either your battery is damaged or USB socket problem

Nope, using another pc did not help. So I am still stuck with bricked phone. I would like to quote the article I linked in the first post because it exactly describes my problem. But in that article wasnt found a helpful solution either.
"...When I charge it, the red light on the bottom just comes and goes. Stays on for a few minutes, then goes off for a few minutes. I let it charge for almost 6 hours like this and nothing has happened. When I plug the phone into my PC you hear the USB connected sound, but right after you hear the disconnected sound, and nothing shows up in device manager. I tried the Vol+ and Power button combo and nothing happens. I tried holding the reset button on the back for 5-10 seconds and nothing happens. I get no vibrations at all. The phone is not detected in any program like SUS, Flashtool, or PC companion. Some times when I press the power button I get 2 red short flashes, I have no idea what this means as it's not consistent, and only happens every once in a while.... "
I have my phone in warranty but my display is cracked a bit and I not original software is installed on the device so I am not sure if warranty wasnt voided by those things. Please help.

Since u have not unlocked your bootloader you are still in warranty. Now only service center can repair ur phone. Dont tell them u have installed a custom rom or rooted ur device if u want to claim warranty.

XSP won't charge or boot

Hi
I am stuck with a phone that won't boot, charge, or be detected by flashtool (or windows) and will not boot in flashmode/fastboot either.
I had plugged in the phone for charging when the battery was considerably low ~ 5-10% before I went to sleep. I remember the red LED glowing, meaning the phone must've been charging.
The next morning I check the phone, the LED was STILL red and the handset was kind of dead - no response at all, whatsoever. Even the reset button on the bacl panel doesn't work (no vibration).
The phone was running BlissPop (5.1.1) with Tangerine kernel.
Now when I plug in the phone for charging, nothing happens at all, not even the red LED. The LED does glow red for as long as I press and hold the power button while it is plugged in (both PC and wall outlet)
I took it to the service center; they say they'll have to change the motherboard. Obviously the phone is not in warranty and there is no way I can pay 10,000 INR that Sony is demanding for the job.
Someone somewhere in the forums suggested allowing the battery to drain completely, but I don't think my battery is holding any charge.
Can anyone help me out?
Thanks

1. Press and hold the reset button for 8 seconds and check if it vibrates. Now plug in charger as there is a possibility that phone is not booting because of insufficient charge.
2. Charge for atleast 20 min without switching on phone.
3. Make sure flashtool is installed properly and so as drivers.
4. Flash Stock ftf
If the above didnt work then try Fastboot mode and simply flash Tangerine kernel.
If nothing works, then its an hardware issue and there is no point in spending 10k in repairing.
Get yourself a brand new Moto G or yureka.

http://forum.xda-developers.com/showthread.php?t=2717303 <- this guy had a pretty similar problem and managed to fix it
I was following the steps he provided: i plugged the phone to PC and held the power button pressed. Surprisingly the PC did recognize the phone after a while- but it was only momentarily and the red LED also stopped glowing. Unfortunately I haven't been able to reproduce a similar situation after that.

bump!
