I followed the steps below
Step one:
Download the special factory image. This image is the WiFi Pineapple MKV's 1.2.0 firmware, packaged differently to allow unbricking. Please verify it's md5 checksum to be 167b1533b9dd5c49f7107413fb960bfa.
Power off your WiFi Pineapple MKV and set the DIP switches to up, up, up, up, down (from left to right).
Connect to your WiFi Pineapple MKV via ethernet and set your network interface to a static IP of 192.168.1.2
Boot up the WiFi Pineapple MKV. After around five seconds, you can navigate to http://192.168.1.1
Upload the factory-1.2.0.bin file through the interface. Wait for it to complete.
Set all the DIP switches back to the default configuration up, up, up, up, up (from left to right).
Make sure the SD card is inserted and powercycle the WiFi Pineapple MKV. Your device will now boot the 1.2.0 firmware. Please wait patiently and refer to the first boot instructions in your WiFi Pineapple MKV instructions. You may skip any information relating to the stager.
You are done. Enjoy your freshly flashed WiFi Pineapple MKV!
Step two.. Logged in. upgraded
At this point everything was running great. I was asked to verify that I was the owner (awesome addon) via lights and it ask me a number of questions to setup the wifi
Step three I logged back in after setting everything up and updated the wifi settings
Green light of death ..
Note:
I just powered it back up. it starts up with a solid green light and a blue flashing light, after about 15 sec the blue light goes away and I am left with a solid green light. I think its laughing at me right now :(
I'll try unbricking it again in a few hours.
