Okay I am extremely frustrated right now! I have an Lg Optimus S running 2.3. The phone was rooted. Well, two days ago it started running slow, so I tried to do a system recovery. Well during this time, my little boy made my phones battery come out.. so the restore did not finish. So now I am stuck with a black screen. The phone will not boot up at all.. it shows the lg logo and then goes to a black screen. Even when you try to charge it. The phone will not boot up in emergancy mode, nor download mode, or it will not let me do a hard reset. I have spent hours and hours reading and trying to downgrade, use kdz but all of them require your phone to be in emergancy mode and my phone cannot be. I tried kdz update and it wont sense my phone.. I guess its right because the computer will not recognize it either. My husband has the same phone type and the computer recognizes his. This is all very frustrating and honestly, if anyone on here can help me.. I would be forever grateful. I will try anything. Please help a girl out! Thank you!
