Infinix X551

I have a problem which am requesting your input.

I was brought an infinix x551 (16+1 L) with pattern lock.

I flashed it with Sp Flash Tool with 16+1 lollipop firmware and it finished successfully but not Booting.

I used format+Download.

Now trying reflashing it l get error 4032.

Does the 16+1L require a different firmware?

Please assist.

Thank you.
