Change of name before filing llp agreement

I guess, it is not possible. You need to first file Form 3 for Intiial LLP Agreement. Then only you will be able to do it.

So, I am guessing, we will first have to file form-3 (Initial Agreement) followed by request for change of name (form-1 and form-4), followed by filing for changes in LLP agreement. 
Or is there a shorter and speedier process?

What if the LLP agreement is not filed at all? will it render the incorporation void?

If you do not file Form 3 for initial agreement, then, as far as I know, MCA system won't allow you to file other forms. However, it does not invalidate incorporation.

For change in name procedure, plz refer LLP rules. I guess Form 4 is not required for change in name and object.

You are correct sir, Form-5 is to be filed for change of name, not Form-4.
Will do the needful.
Many thanks for your guidance, appreciate it.

Namaste,
