That's a pity,
my big annoyance with using Cacko ROM was that issue with battery charging.
But now that this seems to work (for me, unless ) I have the Z as I wanted it, lot of apps (since I use 64-0), no problems installing apps and no worries with battery (at the moment... )
I have just plugged the Z to outlet, I still had some batt left but I want to use WIFI.
It blinked.
I unplugged, tapped on qtopia-batteryapplet, left it on screen showing mid-charge, plugged again and worked
It has worked too many times to be just coincidence! (I want to believe )
I installed Cacko Rom 64-0, and later upgraded to new kernel. Never tried with Sharp 3.13 Rom, though.
