I was trying to manually update my phone from version 27 to version 18. I was using the instructions on xda and I followed the instructions exactly as they said and the phone shut off like it was rebooting however it did not come back on. I waited awhile and nothing happened so I unplugged it and it wont turn on at all. So I plugged the phone into the wall however it wont even show it is charging. Then I took the battery out and now on the screen it is showing a pic of a phone with a line going to a computer. Does anyone know what I did to this phone??? It will not turn turn on or off... it just stays on that screen. Nevermind i figured it out. had to put it back into download and redoe it. i wipped the phone but didnt put it back on.
