ah... forgive what's probably a noob question, but when I start uncart it brings me to the brahma menu. Neither loading a payload or running seem to work.uncart now dumps and decrypts all at once which is much nicer than dealing with the convoluted muti-step process of old.
The option remains to just dump a standard encrypted cci - 2.5x faster than GW, without unique header id.

I've only tested this on cubic ninja and it appeared to do a good job for the most part, but the update partition wasn't decrypted. Not important in most cases, but it should be known.
