Hello there. Two days ago i used the guide to replace battery. I used 99,8 isopropyl alcohol to remove the adhesive. I used syringe to pour carefully and waited till i remove the battery. After that i replaced with the new battery (original samsung). I put everything back as the guide asked. I powered my phone and everything worked fine. I used it for 6 hours and then i went to sleep. In the morning my phone screen was dead. When i press power and volume down i feel a vibration but nothing else. Any ideas?
