Ok, got a solid working root on the non Dev M. Bootloader still locked, have not been able to flash a recovery tho. Now I have a boot into AP fastboot every time the phone reboots. But root works.
Lolz! Used RSDlite and broke my phone with the first attempt. Lousy bootloader! Gotta say this is a fairly robust phone though, I flashed it again with a fresh download and it worked and kept my root!
