Sprint Galaxy S4 dead even after factory reset?

[Aolish]

Hi all, I was hoping someone can help out an old S4 user. I've had this phone for about 5 years. Its been through its fair share of drops and getting wet (not soaked but just wet) but it still kept going till this morning the phone rebooted on its own. In all honesty the phone has been rebooting on its own for quite some time. But this last reboot in the morning seems to have really done a number on this phone. Whenever I turn on the phone now it never goes past the carrier logo screen.

Long story short I've tried several things like trying to get into Safe Mode (doesn't work, assuming I'm doing it correctly), taking out the battery and putting it back in (doesn't work), tried the default battery that came with the phone (doesn't work), tried to wipe the cache data from the phone in recovery mode (doesn't work, it says error) and even tried a factory reset in the phones recovery mode which didn't work either. They all give me the same result, the phone successfully turns on every time but will always get stuck on the carrier logo after the Samsung Galaxy S4 logo and never moves on from there. Any suggestions is greatly appreciated.

S4 was released in 05/2013
If you have had the phone for 5 years then you are talking about the Galaxy S2
Assuming you are talking about the S4 (which I've owned since it initial release on Verizon)

Galaxy S4 randomly reboots

1. Turn the device off completely.
2. Press and hold the Power button.
3. Once the Samsung Galaxy S4 logo appears on the screen, release the Power button.
4. As soon as you release the Power button, press and hold the Volume Down key.
5. Continue holding the Volume Down key until the phone has completed the reboot process.
6. If you can read ‘Safe Mode‘ at the bottom left corner of the screen, release the Volume Down key. Otherwise, repeat the process until you can boot the phone to Safe Mode.
   
   

Galaxy S4 can’t get out of boot loop

1. Turn off the device.
2. Press and hold the following three buttons at the same time: Volume Up key, Home key, Power key
3. When the phone vibrates, let go of the Power key but continue to press and hold the Volume Up key and the Home key.
4. When the Android System Recovery screen appears, release the Volume Up and Home keys.
5. Press the Volume Down key to highlight ‘wipe cache partition.’
6. Press the Power key to select. The phone will automatically restart after the cache is wiped.

I have already tried the system recovery wipe data cache, I get an error and Safe Mode never seems to work no matter how many times I try. I even tried to restore the device to factory defaults. Nothing works, I always get stuck at the carrier logo.

This is a long shot, but it's free and you've got nothing to lose. You mentioned two batteries. Are you using a generic aftermarket battery? I've used them in digital cameras and when they go bad, they can do unpredictable things, like random rebooting. Think of a TV with a bad power cord that keeps going on and off when the wire is "jiggled". Try a good Samsung branded battery if you can get one. Anyway, take the battery you've got and clean the oxidation off the terminals with a pencil eraser. The contacts look OK until you clean them and you can see the difference. Use the eraser to clean the terminals in battery compartment as well.

I have a Samsung S5 and I think to do Safe Mode the camera has to be completely powered off through the operating system, not just pushing the right button.

Good luck solving your problem
