Unplugged my cable while upgrading via Odin My cable was unplugged while my Samsung Galaxy S2 I9100 upgrading with Odin. Now, nothing appears on the screen, even when I plug the charger. How can I fix my device?
You will have to Switch ON the phone in "Safe Mode" by pressing the Volume down, Power, and the Home button all together. Then, factory reset the phone, and upgrade it through Odin; or on a safer side, use Samsung Kies for upgrading to a new OS.
