For the Bluefruit LE Friend, which is based on the first generation 16KB SRAM nRF51822 parts, you must use the 0.5.0 or lower series firmware.
The 0.6.0+ series firmware only works with newer boards based on 32KB SRAM nrf51822 parts like the Bluefruit LE UART Friend. The 0.6.0+ firmware won't boot on older 16KB SRAM parts.
If you are using the Bluefruit LE Connect apps from Adafruit to manage your firmware updates, it should take care of the version differences automatically.
