I'm going to do the manual method. This sequence (from the read me file in the boot image and su package you referred to):
fastboot boot boot.img:
the device will reboot and start in unsafe mode where you can enable adb as root usually on production devices this is not possible.
Be sure to enable adb debugging on menu.
Back to command prompt and then
adb root
adb remount
adb push su /system/bin
adb push Superuser.apk /system/app
adb shell chmod 06755 /system/bin/su
adb shell chmod 06755 /system/app/Superuser.apk
my additions:
adb push hcidump /system/xbin
adb push hciconfig /system/xbin
etc.
adb reboot
Just to add to this story was the frustration I was having was finding all the necessary USB drivers to run both adb and fastboot for this phone. On this model, GT-19250, fastboot will not run without a second special driver (the adb driver is the Samsung_USB_Driver_for_Mobile_Phones_v1_4_8_0.exe which seems to be well known). Took me forever to even find out that I needed a second driver for fastboot. If I am permitted (and learn how) I should upload these files to this site so someone else can be spared the agony.
My only concern is that this is a very new phone with ICS on it that I need in order to make an app that used the new HDP Bluetooth....which unfortunately seems to have some holes. I'm just not sure this older stuff wont be 'bricking'
this device!
and to top it all off I am very new to Android!
