I update my KT to 5.1.0 and it was fine at the begining, (with jailbreak,luncher 1.1.0 and simple screen saver hack)
After several hours ,it's touching control suddenly became mad—— I press the menu and it goes to search, I select books and has no feedback. Clean the screen is no helping. Since the diag mode works fine, I figure it's software issue,so I use dd to clean /var/local and downgrade to 5.0.0, then upgrade to 5.1.0 again.

After these procedures everything works fine for 3 or 4 days then the touch screen became mad again, this time dd is not helping anymore, I try fastboot flash kernel kernel-kt-5.0.0.img and with no luck. The diag mode still works fine so the hardware should be ok, is there any other thing I can do to save my KT? (It can reboot normally,every thing is working other than touching control)
