Battery replacement - blue pulsing light and black screen
Hi - I followed the guide to replace my battery. I put everything back together and my phone wont turn on. I plug it in and get a red light, which turns to green. I try to turn it on and it eventually goes to a blue pulsing light. I have tried power + volume down, and power+volume down+ volume up, and power+volume up+volume down+ home, but I don't get anything on the screen. Wondering if I could have damaged something during the repair?
