baldo Flashing firmware if testing firmware is still installed

-Please note: our market research has told us people buy stuff with closed crypto keys and vendor approved applications like crazy, theref0re the r0ket is compatible with this audience. The original firmware contains some crypto keys to make this possible, so if you flash your own firmware you will lose those forever. We don't want to stop you from doing so (you'​ll loose only the stuff which needs the closed krypto keys), just wanted to tell you before you start flashing. Possibly you want to live on the Bluemchenwiese for a day or so before jailbreaking your badge... 
  
-Please ​also note: Camp hasn't even started yet and we are putting more stuff together on flashing etcSome of us aren'​t ​even at Camp yet. Probably ​just start with the [[simulat0r]] if you want to write your own Tetris NOW.+Please note: we threw away the crypto keysSo if you update from the original camp firmware to the congress firmware you have to replace your l0dabels with current (unencrypted) ones!

 Yes, that's expected. When you flashed the new firmware, you implicitly jailbroke the device and moved on from Bluemchenwiese to Hackerspace... That means you lost the original secret keys forever (unless you manage to extract them from another device, of course) and the old l0dable files are encrypted with those old keys - so you can't install them anymore. You have to install new l0dable files that are encrypted with the new keys (probably those which you downloaded from git and renamed to SECRET.release,​ see http://​r0ket.badge.events.ccc.de/​build ). Yes, that's expected.

 +=== r0ket only displays test output ===
 +
 +If you see the following output after power on and your r0ket doesn'​t do anything else, it still contains the testing firmware:
 +
 +  testing...
 +  flash...ok
 +  ADC...ok
 +  RF...timeout
 +  spi...ok
 +  test done
 +  ready for
 +  takeoff
 +
 +In this case follow the instructions on [[init|init]] to flash the firmware yourself.
