Guest winlinwcn Posted March 27, 2013 Report Share Posted March 27, 2013 I was searching online for how I can I make a back up for Acer liquid A1 to my computer, I found it is possible using SDK. I tried to make a backup using the following adb command: adb backup -all -f C:\backup.ab but i got this error adb: unable to connect for backup even though USB debugging is enabled , and adb devices recognizes my acer. I am using CM7.2 (final improved by Ainilia ) is there any way to creat backup file, on my computer ? Thanks in advance Link to comment Share on other sites More sharing options...
