I had the same problem with my sons phone. 1st do not even install the LG software from the phone. plug your phone into the computer and let it find it... it should load drivers for your phone, tell your pc to allow this then you will get a warning that says it is not a Microsoft certified driver click allow, when its done it will say found new hardware and it is ready to use go to.. START... MY COMPUTER..you will see a folder that has a phone logo, open that and you are looking at the files in the phone..good luck if this works please dont forget to rate
common problem is that the USB plug you using is not the right one, as I have a phone that acts the same way certian plugs charge it but one of my plugs the Windows OS sees it as a new divice added to my computer and promps me to nquestion wheather I want to open the device or other options, common mistake is that not all Nextel/Verizion/alltel smart phones use the same USB to mini pin configiration same with digital camera the mini plug may work on a camera but not you smart phone
Dr Know, doesn't know what he's talking about. I have a LG KF750 and have experienced the same problem.
Solution - Really jam the cable into the socket! The connection is pretty rubbish. The phone charging icon will (with some force and wiggling) appear on screen. Then carefully put it down and don't touch it!
USB charges very slowly, if charging from a dead flat battery it may take a good 20mins of charging to boot up.
P.S. the red camera light is not supposed to come on when charging. Keep wiggling the cable and the light will go off when the phone charging icon appears.
I had this same problem, it's really irritating. Not exactly a full solution, but if you leave your phone connected to the usb for around 10 - 15 mins then disconnect it, remove and replace the battery and turn it on, it should have enough power to boot up, the just reinsert the usb and it should charge.
most probably either the USB port on system is disabled right click on my computer goto properties goto hardware goto device manager in device manager Make sure the USB root hub under Universal serial bus are enabled Check whether u get a section for other devices and whether u get a USB device with a yellow question mark under it or not if yes then the drivers for this device or not getting recognised or USb has been disabled.. Try to disable and enable it by right clicking on it. .... u can try to change the usb port on ur system Try to use another usb cable check the teeth oh the usb cable and make sure whether they6 are in good condition or not make sure that the cable is connected to the phone properly and nothing is lose If still does not work
The jack where u plug in the usb cabke in ur mobile , check for dust,,, to clean dust, take cotton , apply little bit of whisky (wine) not too much ( only whisky works nothing else ) , try to clean the jack and makie sure u dont apply too much of whisky other wise it could get inside ur phone try to clean it and see whether it workx or not. Best o luck
