G901f Unbranded rom needed

I've recently updated from kitkat to an unbranded lollipop rom but the network failed to work . What can I do now ? While flashing I got some error
<ID:0/005> FAIL! (Size)
<ID:0/005>
<ID:0/005> Complete(Write) operation failed.

I then flashed a pit and phone booted but no network.

Can you give me link to some unbranded rom kitkat or lollipop which isn't network locked.
