Tried flashing Beta2 from AOKP three times now and each time, Superuser has been broken. Was thinking I might have messed something up earlier, but validated that Superuser still works fine in other roms.
Also, flashing Beta2 straight leads into a recovery bootloop. To get it to properly flash, I needed to flash AOKP and then immediately flash Beta2 after. Flashing Beta2 onto AOKP... bootloop.
Any information I should pull to help figure out what's going on? Next step for me is going to be flashing Beta1 and seeing if that has working Superuser, and then if updating from Beta1 to Beta2 keeps it alive...
Edit: Beta1 has the same issue. Pure-flash gives recovery bootloop. Flashing AOKPr4 into AOKPCB Beta1 gives broken Superuser.
