Can anyone help. I have been trying to sideload the 4.1.1 update all morning via adb. I believe adb is installed properly. I followed all instructions to get the drivers installed along with adb and when i plug in my device with usb debugging active, it recognizes my device by giving serial # and device next to it. I type in command adb reboot recovery, device goes into recovery, hit power button, then volume up to get into menu where i use power button to install from adb. In the command line, i renamed long zip to update.zip, then type exactly adb sideload update.zip and keep getting "cannot read update.zip". At this point after hours of trying different things to no avail I come to the forums for help. I have also tried leaving the file as is and copying and pasting into abd, didnt work, i also tried update.zip.zip, didnt work. I have no idea why it can't read file. If anyone has come across this and have found a fix, please share.
