See the yellow sticky at the top of the 8300 section for the latest OS for your device and the instructions. The OS is device specific so make sure you get one for the 8310.
As for instructions, follow them exactly and be patient. It can take an hour or longer. If using a laptop, make sure it is plugged in to a charger and it doesn't run out of power.
