    well I have the same problem and I really don't know what to do :(

  • Matt_79 Dec 10, 2008

    Took the battery out to change the SIM (as I have done on munerous previous occasions) after turning it off first and when I restarted the phone I got red flashes from the infrared port area and no joy. Connecting it via the charger to the mains did not help either.

My sony xperia T will not charge

Success story. Disclaimer I haven't notice any damage or
loss of data, However I take no responsibility for any damage or loss of data
that may occur.

My girlfriend has a xperia T and did let it go flat, since
then it didn't appear to charge or switched on.

I had tried allsorts suggested on various websites such as
plugging charger in and out a few times, leaving in charger for 24 hr, plugging
into laptop, and trying to power up with power button and volume up. Red light
sometimes lighting up or flashing but not staying lit.

After playing around with all of the above methods, I
noticed if I kept my finger on power while plugging into the charger or laptop
the red led stayed on until I let go. So I tied an elastic band around the
phone on the power button, then I plugged in the charger, unplugging it,
plugging in again with volume up pressed until I had the red led lit. Not sure
of which combination I did but just when the led was lit (not flashing). I left
it for a few hours while it was plugged in with the elastic band keeping
pressure on the power button. Came back to it and found the phone on and
battery at 100%.

Hope this helps some of you

How do u reset it after it freezeso on the lg lotus screen

I'm afraid you'll have to hard reset your device, in order to sort your problems out. Be warned that a hard reset will set everything on your phone to their factory defaults, for what you'll loose all the programs you have installed, as well as your personal data. To perform a hard reset, turn your phone off completely, by pressing and holding the power button, and answering to the turn off prompt. Then, press and hold the Volume Down, the Call, and the Power buttons, until the LED (at the side of the camera) flashes. Release the buttons. That LED should flash in green/red/blue now. When your device powers up, it should be completely cleared.
Hope it works for you, since this is completely theoretical. I have never done it myself.

Cannot pair lg voyager with jawbone bluetooth.

Mine wouldn't pair either so I went to the jawbone site and I did this and it worked the first time.

For Jawbone ICON, while the power is off, press and hold down the Talk button and slide the power switch on. When the LED starts to flash red and white alternately, release the Talk button.

1. Press the OK Key.

2. Highlight SETTINGS & TOOLS and press the OK Key.

3. Select Bluetooth Menu.

4. Select Add New Device. (If Bluetooth power is set to off, you will be prompted to turn power on. Select Yes and press the OK key.)

5. Highlight Jawbone and press the OK Key.
Enter the PIN "0000" (be sure to enter four zeroes and not the letter "O") and press the OK Key.
