i have samsung j810gf and i did adb reboot sideload in my pc , my phone booted into sideload menu and then i removed usb cable , now i want to exit it but i have tried every possible combination of my phone using power and volume up or power and volume down , although it restarts but it again boots into the sideload screen , and when i hold power and clicks volume up it shows no command .i want to exit it and boot into my stock rom. please help

if u can help by restoring my stock rom it would be best , but if it costs me to reset it i will do it , i have my stock firmware i can flash it again . any help would be greatly appreciated
