i would re download rom (just in case it was a bad download) then i would pull sd card out (just in case, strange things are known to happen) then task 29 then flash sharkie agian. let it boot all the way threw the customs and such. check if there are any issues. to be on the safe side hard reset---clear storage and let it boot threw customs. then check if there are any issues. backup sd card on pc---then re format and insert sd card.

the other option is follow above but instead of task 29, replace with a flash of sprints offical stock rom. in fact try this option first but check if you have issues on the stock rom before flashing agian.
