I tried to install WebOS doctor 224 but Pre3 was hanged and after that, only showed HP on screen. I still tried to remove battery and re-install, but can't fixed.
I do follow instruction as above and still ok from step 1 to step 9. But WebOS Doctor 224 AT&T (Build Att.170.2211) only run to 12% and look like not running anymore.
I'v just update system to WebOS2.2.4.
Please help me to fix this problem.
