hi uniqs...
there's nothing wrong with the installation.. just that the new version is not come with aroma installer like v3 or v4 (the version i used) compared to this LRQ version.. and yes it's look alike the installation hang in the middle.. but it is not... just what until it finished...
as for my two cents.. just stick to the one that works with you ... v3 or v4 in my opinion is more enhanced than the current version...
btw... if got stuck next time... just get back into recovery mode... vol up + home + start button... then just install abyss.. followed by factory reset.. then flash back the new / old rom ... reboot... there you go... good luck!
have a nice day then... cheers!
