Samsung Galaxy Player 4. Gingerbread, I believe. I am stuck. My battery started to fail quickly. I eventually factory reset. Then, during upload I get the TW Launcher error. I click through that and it gives me a black screen. I can't disable the TW launcher because of the black screen. I tried to download GO launcher, but because I factory reset, my device did not recognize my google play account as active. Google Play gave me an error saying that I did not connect through my device yet. Which I can't now because of the black screen. I tried to sideload a launcher through USB, but it gave me the error that my USB debugger option is not set within my device. It gave me instructions to select this option, but I can't set the debugger option because of the black screen. Now I am stuck with a black screen and no way to upload a new launcher, assuming that is the cause of everything. Now my player sits in the drawer unusable to my knowledge. Help would be appreciated.
