For backing up data from and repairing a stock Samsung Galaxy S2 (see How to copy / modify data from a soft-bootlooping Samsung Galaxy S2 (GT-I9100)), I used a recovery ROM (PhilZ-cwm6-XWMS3-FOP-5.15.9-signed.zip
, SHA256: 406a617e8b378384bde40dd2dc6234c0660a1b4f592b6c25b3be6b6f078b9eec). This recovery ROM works without having to re-install the stock firmware (which, on this phone, is normally required). As a side-effect, it also installed the "Superuser" app, making it possible to become root
.
After turning on the phone a few times, I was asked whether I want to allow "Automation Test" to gain super user privileges. What application is that and where does it come from? It seems like it is stored here: /system/app/AutomationTest_JBUP.apk
