won't reset chip after dfu

Question

Hi, 
 I am using keil uvision 5.17, SD 130, nRF 51822, dualbank bootloader. 
 
 I have programmed own application and merged bootloader, application, soft device. 
 I can do dfu as many as I want, 
 but the problem is I should push reset button whenever I finish dfu. 
 If I don't push reset button, I can't connect with smartphone. 
 
 My application have programmed from s130_hrs_with_dfu example, 
 I removed all of code exept dfu and device manage service. 
 Which part should I check to fix manual reset problem?

 Solution :
..\dfu\bootloader\main.c 
 set(if you are using timer1, timer2) 
 if (bootloader_app_is_valid(DFU_BANK_0_REGION_START) && !bootloader_dfu_sd_in_progress())
{
 // Select a bank region to use as application region.
 // @note: Only applications running from DFU_BANK_0_REGION_START is supported.
 bootloader_app_start(DFU_BANK_0_REGION_START);
}
 
 to 
 if (bootloader_app_is_valid(DFU_BANK_0_REGION_START) && !bootloader_dfu_sd_in_progress())
{

 NRF_TIMER1->TASKS_STOP = 1;
 NRF_TIMER1->TASKS_SHUTDOWN=1;
 NRF_TIMER1->EVENTS_COMPARE[0]=0;
 NRF_TIMER1->EVENTS_COMPARE[1]=0;
 NRF_TIMER1->EVENTS_COMPARE[2]=0;
 NRF_TIMER1->EVENTS_COMPARE[3]=0;
 NVIC_DisableIRQ(TIMER1_IRQn);

 NRF_TIMER2->TASKS_STOP = 1;
 NRF_TIMER2->TASKS_SHUTDOWN=1;
 NRF_TIMER2->EVENTS_COMPARE[0]=0;
 NRF_TIMER2->EVENTS_COMPARE[1]=0;
 NRF_TIMER2->EVENTS_COMPARE[2]=0;
 NRF_TIMER2->EVENTS_COMPARE[3]=0;
 NVIC_DisableIRQ(TIMER2_IRQn); 

 // Select a bank region to use as application region.
 // @note: Only applications running from DFU_BANK_0_REGION_START is supported.
 bootloader_app_start(DFU_BANK_0_REGION_START);
}
