Yeah, I haven't flashed to 1893 either yet.
Can anyone at least confirm if the issue with the power off and no boot afterwards is solved? From the list of fixes it seems so but that has happened in the past and it's still there.
Also, any differences in the mem settings? Few months back Tony said some improvements were on the way, including control of the tRD/Perf Level but so far nothing. Is it there yet, anyone?
