I am sorry for posting here but I didn't know how to post in bug tab
Anyway, I can't understand this message, this screenshot from my xperia l device, this app was working in beta 4 without any issues
Second, I think there are something in data connection, sometimes gone and sometimes work but slowly till turning it off and turn it on again , NOTE .. I faced this error in a good single place
That wasn't in beta 4
this question belongs here http://xdaforums.com/xperia-l/development/app-recoveries-recovery-installer-t3187915 not here in CM12.1 development
and btw just downlad latest 1.1.1 recovery installer, it will work
