Stucked in Bootloop after installed ifixit battery

Hi everyone, my iPhone 7 is stucked in a Bootloop after installed ifixit battery, I have tried several things like:

• Hard reset, (volume down + sleep button for 10 seconds).
• Factory reset, not working because is stucked in bootloop.
• disconnected and connected battery cable few times, with no luck.

What can I do ? I think my battery arrived DOA, can you please help me ?

Thank you!
