I came out the same error on my Samsung Galaxy Ace.
'This solution did not work out, because I could not go to Settings po this method.
What I did was this (and I worked, I assure you, and did not lose any data, except that the Home screens are cleaned and returned to their default settings)
-> Try to access the Internet pure insistence.
That activates the wifi, back to pure insistence. Try pressing any link of a message, to enter the browser, or also through any application that can be accessed either through notifications (application of weather, notes, etc.), applications always have some link to their website of development of application tucked between the application, what counts is accessing the Internet.
-> Once inside internet in search bar, search google play and click a link that takes you to the htttp: //play.google.com and derivatives
That will open a window that will tell you:
Complete action using
-Free
• Google Play
Select google play, and once inside the bar busadora, looking for "TW launcher android", will launch pure substitute for tw launcher applications that will generate errors, install any (the first or with the most stars) because serve you to enter the desktop and the applications menu, and adjustments.
Once installed, hum "open" and after a while, click the button in the middle / Start button (the only square button), will ask you choose to open the desktop, or TW launcher (the failed), or new application you installed (the new application-desk) obviously choose the new application, and once you open your new desktop once you go to
Settings-> Applications-> "Manage Applications" -> (upper tab) "All" and looking at the ("damn") TW launcher, you click force stop, and then delete data.
And after all is rosy, you return to the Home screen if you want you choose TW launcher and go to settings and desintalas the new application you installed, and now this, TW launcher already returned, but not before losing (as you You realize) the order in which you had your screens.
