Stuck in bootloop after replacing battery
So replacing the battery from ifixit went like this. After replacing the battery the phone was stuck in boot loop. I tried a few possible solutions but whitout any luck. Luckily i did not throw old battery away so i replace the new one with old one. Phone did turn on and it is working. I switch it again to double check if there was bad conection but same story as before so i switch it back to old battery and again it is working. What do you think went wrong ?
