If it was working under DPSK Mod/DPSK Demond, then all you have to do is

Thanks a lot Cinaed for the tips, in particular, the symmetry order and CMA
equaliser.
I did what you suggested about sps variable. However, it didn't help.
Besides as far as I know form GNURadio documentation, samples/symbol is
referring to the samples representing a single constellation symbol
m-psk for m=2, has 2 samples/symbol and log2(m)=1 - or 1 bit per symbol.
Also, the polyphase clock has an input of 4 samples and output of 1 sps.
It should have input of 2 sps and output of 1 sps.
Just change the sps everywhere to 2.
Also, note there are only 2 symbols in the symbol map of the
C
