Flashing

NOTE: During configuration or flashing a device, the only things that should be hooked to the device is the computer and power.

Flashing OpenWrt

This device is NOT RECOMMENDED for future use with OpenWrt due to low flash/ram.

DO NOT BUY DEVICES WITH 8MB FLASH / 64MB RAM if you intend to flash an up-to-date and secure OpenWrt version onto it! See 8/64 warning for details.

This device does not have sufficient resources (flash and/or RAM) to provide secure and reliable operation.

This means that you will not be able to install many packages, and that you might experience crashes due to OOM situations more or less often. See OpenWrt on 8/64 devices what you can do now.
