Hi,
I already wrote down my phone for losses, thinking that the motherboard failed - similarly stated the service technician. After inserting the original battery, the phone did not respond at all. After inserting a non-original battery, pressing and holding the power button, the phone began to turn on and off. Periodically. But nothing else - it didn't respond to any pressure. After replacing the battery with the original one, the phone would not turn on at all. After replacing the battery again, pressing and holding the button, the phone turns on / off - the model name is displayed, but nothing else. After connecting the phone to charge, the charging picture shows - but only if it is turned off.
What could be the reason for this behavior of the phone?
Best regards,
Michael

It looks like you are right because the message popped up: "A custom OS can cause critical problems in phone and installed applications. If you want to download a custom OS, press the volume up key. Otherwise, press the volume down key to cancel . " 
Additionally, the PIT file, and in Odin's options you select re-partition.
