Did I damage the battery?

Hi!

I used the tear-down guide to change the the lcd/glass/touch/frame assembly. I had the right tools and was very careful. But the battery gave me problems, the glue held up a good fight. I didn't know that there was a small control board in the upper part where the connector sits. So i lifted the battery all the way around, and it got a little bent while doing this. When i put everything back together, it wouldn't start. I plugged it in the charger and the LED blinks red. The battery was fully charged before i took it apart.

I suspect that i broke the battery, trying to get it out. Would you agree?

I tried to take the connector of the battery and reconnecting, no change. When i plug the charger in, while the battery is disconnected, the screen shows the battery logo. I can even turn it on for a few seconds, it vibrates and shows the google logo. then turns back off. I guess because of the missing battery?

Do you think it's safe to order a new battery, and that it will work again?
