Hi! I`m trying to fix my old Samsung Galaxy S2 GT-I9100 but i have problem and i don`t know how to solve this. When i power on my phone i get the yellow triangle and the message "Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again" I have Kies but phone won`t connect. I try to Flash using original firmware with Odin but fails every time. I really need help. I have Samsung usb drivers on my pc. Odin detect my phone but i just cant find the way to fix the phone! Thanks!
