K810i wont turn on

move on to near by service center if u have valid warranty..
might b issue with the ROM OR DISPLAY problem..if its display, replace with the new one..if its ROM then they will flash and give u

I'm 100% sure on the Xperia T(I have a ZL) but with most off the Xperia's there is some sort of removable back panel or a hinged flap that opens up under the panel/flap there is a orange button that you will need a pen to press and hold. hold this button down while holding down the power button it should vibrate once, keep holding the buttons then it should vibrate 3 times, now let go of the buttons and your phone should stay off.

try this: take the cartridge from both compartments. take out the cartridge. press the on button for 30 seconds. place the batteries back into the toy. try turning it on.

1.Check the device's battery level for at least two bars of strength.
2.If the battery level is low, charge the battery.
3.If the issue is not resolved, remove the back cover.
4.Remove the battery.
5.Wait 10 seconds.
6.Press and hold the W key.
7.While pressing down the W key, re-insert the battery.
•The device restarts and after approximately 15 seconds, the 'Recovery' screen appears
•Release the power button but *continue holding the home button*, for another 30 seconds.
Step
Thanks

let it sit in the charger for 1hour then try to turn on your phone. it could be that the charger cannot charge the battery and turn on the phone at the same time and the battery is too weak to turn it on and needs a better charge.

On your phone the program has broken, it is necessary to reinstall it. To give to repair.

Hi. Just try pressing the power button and reset button at the same time. Unit will vibrate when reset. You can use a paper clip or similiar to hit the reset button located behind the screen. After that, plug your device to charger for at least a couple of hours. Hope this helps.

First thing is never remove the cable without stopping the USB connection from system tray. Now, as your phone has gone kaput, you will have to re flash the firmware. Checkout some SE forums like esato.com,se-nse. Use a memory card reader to copy the contents of your m2 and don't keep it inserted in the phone while flashing.

If your phone is still under warranty, i suggest you take it to the service center.

My friend had experienced the same problem with her SEK810i. We both bought the K810i last year. Mine is working perfectly fine. but hers suddenly froze, and she cannot even see the phone menu. we tried to go to a service center but they couldn't fix it. So she just bought a new phone. also fro the SE phone collections.
