I've already used avast! Mobile Security to set up a fairly resistant anti-theft system on my Triumph. My problem is that a slightly more tech-savvy thief might know to enter CWM and just wipe /system from there. Then I found this Tasker plugin, which claims to be able to execute Linux commands. This got me thinking that I could set up a Tasker profile that, when I send my lost Triumph a specific text message, would execute a series of commands that would replace CWM with the stock recovery image; I have the stock image still on my phone, named "recovery.img.backup" or something similar. I know that the thief could just enter Download Mode and replace the recovery image there, but that requires a computer and a microUSB cable, whereas wiping /system through CWM can be done with just the phone. Swapping recoveries could buy some time. So, my question is: is there a way to modify the recovery image in userspace? And if so, what commands would be necessary to do so?
