Outer buttons stopped working

When the it is blinking the phone is resetting. There are several reasons for this. Once the blinking stops and Date & Time appear, your phone should be operational again. Check the buttons for programming by using Feature *0 and pressing any button to verify it is programmed. If not you might have a bad phone. Try swapping phones with a working one of the same type. This will tell you if your phone or port are in trouble by where the trouble goes.

Then it is just screwed up

Use Nokia Original cable.I've tested.

Go into settings and open phone settings and then display settings

Try this fix, turn off your computer properly then unplug the computer from the wall socket, then press the power button and hold for about 3-5 seconds. Then plug your computer back in, restart the computer then wait for the boot to settle into Windows.
After doing those things plug in a USB device into the same port as you have been doing. It should work now, if it does not plug it into another port if it does not go to all of the ports and try them all if none of them work then you cable may have come loose on your board or it is a bad USB HUB on your computer it is obvious it is not the unit if it worked on another computer.
You will have to replace it or if it works on one of them then change out the bad one. Replace it! Or go and get a 4 port USB extension using just one of the USB ports. So that you will have more ports without the fix. Replace any worn parts or devices that do not work anymore. John

My LG phone also does I just delete my whole inbox and sent messages it worked for me, hopefully it'll work for you too. :)

It seems to be a viral attack. Visit the nearest Nokia Care and have the firmware re-installed. That should remove the virus and then install an anti virus SW from www.getjar.com or www.dotsis.com.

Hi. First of all, I think the hard reset is not the first solution, but it's the last and the absolute solution. But in case if it is needed you can perform it by: The phone buttons + reset & power = hard reset. Firstly, tap the Start and the Settings. There, find the Sounds & Notifications. Ensure that the first 3 of the checkboxes are checked. And select the second tab to configure your notification sounds and vibration settings. After you've done these, you can try to set an alarm and check if your PDA notifies you. If not, you can also give a try to this free alarm application (http://www.ageye.de/download/galarm.cab) for your PDA. If none of these work, you can try to hard reset your device, but you should backup all your data before a hard reset since all the data will be lost after a hard reset. Hope this helps.

connect it to the computer and charge 4 round bout 30 min n take it out and hold on wen it comes up it should work again dats wat i did wen dat happened
