Hello, I replaced the following parts in my galaxy s8 -Battery -IO flex (charging port) -Headphone jack -Wireless charging flex Reason for replacing parts: One night I was using my galaxy s8 last night and I got a low battery notification so I plugged it into my official Samsung charger my phone stayed at around 5% and slowly dropped over the course of around 30 minutes until it hit zero and died. I left it charging overnight and I am unable to get it to turn on. I replaced all of the components listed above minus the wireless charging flex (I broke it taking the phone apart so I had to order a new one). the phone turned on no problem except I received the error “Battery temperature too low to charge” when attempting to charge the phone. I did some googling and determined that the issue was with not having a wireless charging flex so I ordered one. A few weeks later the wireless charging flex arrived and I installed it in my phone. Except now my phone will not turn on or charge. I have completely resembled the phone as many on the form said to do but I cannot get it to charge or turn on. I have taken the phone apart a few times and ensured that every connecter is connected and making good contact. I am out of ideas any suggestions welcomed
