How to enter flash mode

Power + Volume Down + Home

In some cases, using power button to boot into Download Mode doesn't work. Instead, while pressing Volume Down + Home, connect the device to PC via USB. Don't release the buttons until you're in the Download Mode.

Installation

Use pmbootstrap to build your own installation image.

The nonfree-firmware adds the required binaries for Wi-Fi. This should be installed by default.
