EK-TM4C1294XL: Can't program Tiva TM4C1294XL via CCS or LM Flash, Hibernation Mode

Part Number: EK-TM4C1294XL

Guys, I'm new to Tiva C and was playing around with the hibernation mode to a point where I can't program my board again.

Both CCS and LM Flash Programmer give the same error: Cannot Find Target Device!

Is there any way of doing a hardware reset?

Here's the last code I downloaded into the uC:

#include <stdint.h>
#include <stdbool.h>
#include "utils/ustdlib.h"
#include "inc/hw_types.h"
#include "inc/hw_memmap.h"
#include "driverlib/sysctl.h"
#include "driverlib/gpio.h"
#include "driverlib/timer.h"
#include "driverlib/pin_map.h"
#include "driverlib/debug.h"
#include "driverlib/hibernate.h"

int main(void){
    uint32_t ui32SysClock;

    //

    //
    ui32SysClock = SysCtlClockFreqSet((SYSCTL_XTAL_25MHZ |
                                       SYSCTL_OSC_MAIN |

                                       SYSCTL_CFG_VCO_480), 120000000);

    SysCtlPeripheralEnable(SYSCTL_PERIPH_GPION);
    while(!SysCtlPeripheralReady(SYSCTL_PERIPH_GPION))
    {
    }
    GPIOPinTypeGPIOOutput(GPIO_PORTN_BASE, GPIO_PIN_1);
    GPIOPinWrite(GPIO_PORTN_BASE, GPIO_PIN_1, 0x02);

    SysCtlPeripheralEnable(SYSCTL_PERIPH_HIBERNATE);
    while(!SysCtlPeripheralReady(SYSCTL_PERIPH_HIBERNATE))
    {
    }

    HibernateEnableExpClk(SysCtlClockGet());
    HibernateGPIORetentionEnable();

    SysCtlDelay(1200000000);
    HibernateWakeSet(HIBERNATE_WAKE_PIN);
    GPIOPinWrite(GPIO_PORTN_BASE, GPIO_PIN_1, 0x00);

    //HibernateRequest();

    while(1){
    }
}
