I glad for those of you having success flashing over the previous version, but for me it's just not an option I want to consider. The lack of functionality still stands, your settings might have "stick'ed", but you won't be able to change your ringtones without going through some loops, and won't be able to change your system-wide LED settings at all.
And that's what we have found thus far, there may be more little bugs, so I'll stick to 0.11.19 for now, since it has worked well for me so far until some of these issues are resolved.
