Same issue for me. I plugged in the new Battery what iFixit sent me. Phone wont turn on, neither shows anything on the Display. With the Old Battery it turn´s on and shows diffrent things on the Screen, so the Screen is not the issue. With the new Battery it remains completly dead, even plugged in.

Hey Guys

My Note 8020 died in my vacation. I wanted to boot, everything normal until the code verification for the SimCard poped up, a error occured and the table restartet imediatly.

Its startet staying in a Bootloop. Then somehow everything turned black.

Now its not responding. I plugged in the charger an nothing happens. No vibration no screen turning on no nothing....

I dissasembled it and took out the battery. I thought maybe a hardreset ( taking away any current ) will do the trick but the problem remained.

I can press whatever button I want or take any charger or cable ( I tested a few ) I want it remains dead.

Now the Li-Ion Battery is a 2 Cell build together parallel. So the current is 3,7 Volts.

I checked the voltage and found out that I have 3,2 V on both sides.

Now is 3,2 Volts for a Li-Ion less enough to say its dead? Because I dont know what else to do to get it back to life.

I know that LiPo Batterys are dead under 3,3 V but its said that Li-Ion is dead from less then 2,5V. Any ideas?
