Hi hoping someone can help me with this please:

I am trying to upgrade my lx2 to vix 4.0.5 and have downloaded to USB but running through the instructions nothing happens on the front screen to indicate to press the volume + to start the upgrade and it boots into version 3.2.

I have tried a clean formatted fat32 usb and tried downloading the firmware from within the manager but once I have done that and tried to install the box doesn't seem to start any upgrade (although USB is flashing away) and all I have showing on the screen is Error - Tune Failed. the front screen is showing backup Manager and if I remove the usb and plug into computer I see a number of folders.

any help at all would be greatly appreciated I want to move from 3.2 which seems to have stopped working for me.
