ok got it.
Flashed stock recovery, wiped everything, locked bootloader. I guess I am 100% stock now.
Phone is booting ok.
I will try to use Nexus root toolkit to
2, flash CWM recovery
3, flash superSU
Hope it will work ok now.
What is your take on what happened ?
First Android was a... HD2, loved it.
Went on to buy a Galaxy Nexus, LOVE IT.
Got an iPad2 for a week, hated it!
Bought an Iconia A501: great piece of HW, so many things you can do with it, but limited screen and audio...
Now have an Iconia A700... AMAZING! 1080p movies experience is magnifique... + can plug anything onto it
