I currently own a Samsung Galaxy S2 HD LTE SHG I757M.
I tried to root it, and didn't think to back up anything. I'm currently stuck on the CF-Auto-Root screen with the red droid, turning off my phones just brings me to this screen. Earlier I was stuck at the error during upgrade screen. I honestly have no idea what to do, any help is greatly appreciated.
remove the battery of your phone, wait 10 seconds, and put it back in.
press and hold volume down, home and power buttons until the phone turns on.
it should show the download mode screen. look up on google images to see what the download mode screen looks like.
if it boots into download mode, take out the battery again, and leave it out for the time being.
go to sammobile.com, or samsungupdates.com, find your phone and region, and downlaod the file.
look up on google,
"how to unbrick phone with odin"
follow whatever directions you find easiest to follow.
you will have to download odin first, a google search should find a download easily enough.
