Oh, that's bad firmware avoid doing a factory reset as you can get it working without losing data (factory reset most of the time wont work when it boot loops on animated samsung logo like that.)

You will need to reflash the firmware on that phone using ODIN flasher if you want to keep the data.

Download the Samsung Firmware from here:

http://updato.com/firmware-archive-selec...

To choose the correct firmware, compare the CSC code (Region / Carrier) that is displayed in the recovery menu:

To boot recovery mode on the phone, take battery out (wait 5 seconds) or force turn phone off via power + volume down for 8-10 seconds then quickly hold power and volume up until it shows (vibrates and shows samsung logo) It will most likely say booting recovery. Let it boot and you will see it display what I said hopefully. Firmware build version information is displayed at top of recovery menu if you want to keep note of it, it's useful to know to help identify which firmware is best for your phone.

It will print in the recovery menu applied CSC code OPS or something like that.

Once you have downloaded the correct firmware, you will need to open up odin

Good instructions on how to use odin are here:

http://updato.com/how-to/how-to-install-...

Alternatively you can use Samsung Smart Switch to identify which firmware is right for your phone:

1. Open up smart switch after downloading and installing it:

For below check the back of the phone / behind battery for S/N and IMEI.

2. Enter Model Number (Use capitals):

http://prntscr.com/eurze9

3. Enter Serial Number:

http://prntscr.com/eurzu7

4. The software should display something like this:

http://d38v16rqg5mb6e.cloudfront.net/wp-...

(BTU) is the region code to identify which region firmware you need for your device, just make sure to use latest one to avoid issues with flashing older firmware than the one you already have on your device.

But don't use smart switch or samsung kies to flash firmware on phone if you want to keep data though.

How do you add Firmware suggested if you can't even get phone to stay on?

Because the phone is supposed to stay on while it's in download mode. If it does not then I would recommend trying another battery first.

Try to perform a factory reset. Pull the battery from your device. Then, install the battery back. While off, simultaneously hold the power button, volume down button and home button until you see a menu at the top left. Release the buttons and then choose factory reset. Wait a few minutes and that will solve your problem.

Just a shot, but try removing the battery and holding the power button down for 10 seconds or so then putting the battery back in. It can remove some residual power that can build up within the power management. Also be sure to use the OEM charger AND charging cube.
