A friend is getting rid of all his old geek stuff before emigrating, and he's given me a second-hand ViewSonic Viewpad 7 (Model VS13761). Problem is, it's locked and he can't remember the unlock pattern, so I want to reset the device to "factory mode" and start over.

I can get as far as the "enter Recovery mode" screen by powering it down, then holding down Volume Up + Volume Down whilst pressing Power - but it never gets any further, just sits there with a screen saying "enter Recovery mode" and a picture of some birds.

I've seen forum references to something called SUTL2 but Google hasn't turned up any more useful details. Any ideas?

  • Is the ADB usb debugging mode activated? It can be used to gain access. Else there's the password/screenlock recovery procedure (after a bunch of failed attempts). You need your friend to help you with this though.

  • Yes, USB debugging is enabled. Whatever that is... can you tell I know next to nothing about Android devices? :) Commented Jan 12, 2013 at 14:06
  • Fine. 3.2..1 hacked: there's p2p-adb's antiguard to do this. background here. You can install it using the Android SDK's adb binary (adb install app.apk)

  • you then need to launch the app manually: adb shell am start -S io.kos.antiguard/.unlock (or just download the whole p2p-adb package and run it)

  • Else, just go ahead and use adb to root it using one of the many exploits, e.g. here (and then use p2p-adb to read the screen lock pattern). If that fails, let me know.
