Thanks a lot, I finally managed to get it working, as mentioned I'm a total newbie :-) But I found the steps on how to install PD98IMG.zip on the xda-developer forum.
Finally I followed these steps (also found on the xda-developer forum) in order to get root
also if you wanting root you need to download here http://rapidshare.co.../gfree_root.zip
unzip to the root of sdcard
then put phone in to clockwork recovery,plug usb in and go to mounts and storage
mount system and mount sdcard(should both read unmount )
adb shell (# will appear)
cp /sdcard/superuser.apk /system/app/
cp /sdcard/su /system/xbin/
chmod 06555 /system/xbin/su
unmount system and sdcard
Everything seems to be working now, Titanium backup / MyBackup Pro etc can get root.
However If I try to run the "Superuser Permissions" app it force closes with the message :
"The application Superuser Permissions (process com.noshufou.android.se) has stopped ......
Any hints on how to fix that ?
I tried clearing the data for the app, but that doesn't help.
Did you get root on the DHD using this method with the latest OTA already installed? eg. 1.72.xx?
Or, did you have an old version of the system software?
EDIT: Ah, I see, you need to have Clockwork Recovery already installed. Nevermind.
