While I don't want to discourage you by helping on development (by any means),. consider, that proper evaluating of CSSU-devel fixes/bugs is much harder than things, that you just failed to achieve.

I mean, that if you've failed to fix gmail access, broken pictures etc - which are amongst most trivial things to fix permanently, to be honest - you may have great trouble properly detecting and reporting cssu-devel bugs.

Of course, all of this may be easily overcome by learning, but then, you wouldn't have any problems with glitches, that made you change your device so circle loops here.

No disrespect or mocking meant, just honest opinion.
