First off my phone, Galaxy S4 Model SGH-I337 running Android 4.2.2 rooted. No custom rom installed, i.e. Cyanogenmod. I recently bought some new batteries and a new charger which I had been using for about two weeks before my problem arose.
I came home one night plugged my phone in to charge and woke up to find it unresponsive. I tried a battery pull and found my phone turns on for about 3 seconds showing the samsung custom screen with the padlock only to shut off again. Same thing happens not matter how many times I perform a battery pull. I tried plugging into my computer but the phone is not detected.
I tried a battery pull and booting into safe mode and debugging mode but the phone just shuts off after 3 seconds no matter what.
I'm not sure if this is a true hard brick since when I perform a battery pull the phone starts and the buttons seem to work, at least enough to enter safe or debugging mode.
I have not seen any threads where the phone momentarily turns on after battery pull only to shut off quickly.
Has anyone run into this problem before and is there anyway to fix it???
