Hello.
Today I finally received my Alfa AP121U router. It has stock Alfa firmware on it.
As I understand, I need USB/Serial to UART adapter to reflash my AP121U to OpenWRT or Pineapple using "Mark IV Clean Flash Instruction".
But I would like to know, is it possible to make a backup of the stock Alfa firmware before reflashing it to Pineapple? May be after some time I would like to return to the stock firmware.
The same question was asked here, but does not have answer: http://forums.hak5.org/index.php?/topic/27947-alfa-ap121u-custom-alfa-web-admin-help/
Also I have found this topic: http://forums.hak5.org/index.php?/topic/27203-ap121u-flashing-stock-alfa-firmware/ but as I understood, using this instruction I will get OpenWRT firmware, not the Alfa stock one?
