I had rooted my phone ten days back but lost the root somehow in between during some updation, since I tried so many root tools on my B92/ Wickedleak Wammy Sensation and my cell did install SU by those scripts. However, neither Titanium Backup, nor any other root apps were function, they just used to write that no root acquired, check for root.....i also started getting segmentation fault error messages.....while using this script, I first clicked on Unroot, it completed successfully....to my surprise, after reboot...my Root had started working again !!!!!!
I then clicked on root option and it confirmed that device already has a root....i guess the unroot command with this tool had deleted some files which were blocking my hitherto rooted phone
either way I am damn happy not to be living with a non rooted phone after 3 years of android experience
thanks a lot guys.
