I promptly attempted to restart it through pressing the power button, but had absolutely no response.
Then I tried replacing the battery and the phone device on normally right away, with the Galaxy S4 logo shown as usual, but turns off after a second of the logo display.
Attempted getting into both the download and the recovery mode, no response.
Anybody know what's the issue here? Phone has been rotted and flashed with SlimBean ROM, it has no issues leading up to the event today. Please help!
