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...
Thanks in advance.

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

situation now, more than 30h of charging, is changed a little now if a push the power button the red light blinks but no reboot no vibration nothing at all.......is it worth to try another battery?
please provide me some guidance.

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%

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.

I was on 80%! Strangely enough however, the vibration is back when I press vol-up and power. Still no display though.

Flashtool doesn't recognise my phone. The only sign of life is the 3 vibrates when I hold vol-up & power

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.

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.

Htc stuck on charging screen!!! Help!!

Try holding the power button and volume up button at the same time for about 15 seconds. That should force restart the phone

There might be issue with offline charging of the rom or might be in the battery or adapter. Try using other adapter or battery.

Note 4 wont respond at all

Hey everyone,
I received the phone couple days ago and while its not new its in pretty good shape, i think. So when i started using the phone i noticed that there was a lot of lag waking it from sleep after extended times of inactivity so i decided to factory reset. The day after everything seemed fine with one incident where i left the phone for like 30min - 1hr and it took 10-15 min to wake up. The following morning i woke up and the phone lagged again for prob the same amount of time however the next morning i.e. today i wasn't getting anything after 30 min so waited another 30 min and realized something is wrong so i attempted the hard reset and other tricks (take out battery and hold power button[1min,2min or 3min], hold vol+/-, the home button and then the power button) but nothing happens on or off the charger, no LED, nothing....
Please help!

I suggest you return the device if you can.
Seems like Your device is hard bricked or maybe motherboard has some serious issues
Try connect to computer see if pc detects the device.
Try another battery maybe battery is dead
If you able to go into download mode then flash stock firmware with pit file.

Well, when i tried plugging it into the computer the only notification i get is the sound of the device being plugged in but the Note doesn't respond and nothing comes up on the computer.
As for another battery i dont know where i can get one to test it.
I cant go into download mode; the screen doesnt turn on, no led, nothing. Its like somebody poisoned the phone in its sleep, it is really bizarre for phone to die like this because you think u would see some signs

Phone is hard bricked and motherboard is almost dead.
You can still bring back to life if you able to find a debrick.image for your model in xda
Its complicated and need patients to do it
If you have enough knowledge then do it or otherwise you have to replace entire motherboard.

[SOLVED] Nokia 7 Plus dead/bricked?

Hi all,
My dad has had this Nokia phone for around a year now, it has been running smoothly all the time and never fails on him. But this morning the phone suddenly cannot boot anymore, plugged into charger, still nothing. It will not vibrate, no display, just nothing. I have tried PWR+Vol+ and PWR+Vol- still nothing... My dad told me that the night before it still had around 60% of battery reported by the SystemUI. Suspecting it of being briced (all of a sudden), is there anything I can try to revive this phone before sending it for repair?

May Be Fault Charging IC or loose battery connectors

Problem solved.
Went to a local repair shop and they replaced the motherboard for my dad, free of charge with warranty issued directly from Nokia.
