Galaxy S3 turning on and off repeatedly even after factory reset I have a bricked samsung galaxy s3! It is shutting off and on again and I need to remove the battery to make it stop. I have tried the following...

-tapping out stuck power button

-options in recovery menu (reboot, wipe cache, wipe data and factory rest)

-I have wiped and installed fresh from Odin, which was difficult because my charge port is apparently not working great.

Once I reset with Odin my phone booted up nicely and walked me through setting up my phone. Once i got to the main screen my hopes and dreams were promptly crushed and the phone started shutting  down and restarting again..

Thoughts?
Reload your BOOTLOADER because that is what will be stopping your device from booting sincerely it works a bit like BIOS. I, sadly, dont have any tips on how to do so though. Google search maybe?
