Wrongly filed 3cb instead of 3ca

I have filed 3cb for an LLP for which 3ca is applicable. I cannot file a revised 3ca for the already filed 3cb as two are different forms. I am only able to file an original 3ca or a revised 3cb. The ITR has also been processed. What are my options? Should I revise the ITR and file an original 3ca? Or is there some way to withdraw the already filed 3cb and file 3ca? Please help.

Thanks in advance.
