I managed to uninstall and reinstall Trook (from adb) on the 1.3
softroot :
>$ ./adb connect
192.168.0.109:5555
>$ ./adb uninstall com.kbs.trook
Success
>$ ./adb install Trook-debug.apk
494 KB/s (151652 bytes in 0.299s)
pkg: /data/local/tmp/Trook-debug.apk
Success
Hope it helps some who struggled to do it, like me ;)
