Problems updating to Lollipop

[Mozness]

I need help updating my phone to Lollipop. I have the latest PC companion installed and I get to the step where I need to hold down the volume key while inserting the usb cable. A red light flashes and then nothing.

Have you completely turned off the device before connecting to computer? Do you have any antivirus or firewall that could block the update?

Hi,

Also make sure that your battery is fully charged or at least 80% charged. And when you are connecting the phone, hold down the volume down(-) button before you connect it via the USB-cable, and don't release it until PC Companion goes to the next step.

So now I get two things that can happen:

A) Nothing or

B) A battery charge indicator.

What do I do now?

You may need to perform a software repair using PC Companion.The process will erase all internal memory.You might need to charge your device for about 1-2 hours before so the device has at least 60% battery.

Make sure the device is not connected to computer or laptop and turned off (sometimes you have to press power button and volume up until the device vibrates 3 times or on some devices you have to press the small button near the SIM tray or on the back of the device).

Open PC companion->support zone->phone/tablet software update->repair my phone/tablet blue highlighted.Follow the steps given,do not connect your phone until prompted to press volume down while plugging USB cable. If PC companion does not start the repair process, you might need to run it in compatibility mode with Windows 7 (in some cases XP).
