Rooting Android 2.2 (Froyo)

There are many apps which will help with rooting Froyo.  The two I have tried are:

z4root
Visionary

Both cases require USB Debugging enabled.

z4root did not work for HTC Desire HD.

Note of caution:

Rooting has a few risk just as going into operation is risky.  If it works, it is fine but when it fails, there are a lot of complications.  It is good to have a copy of your ROM so that you can flash back should you need to or have a service center close by to help you.

Reason for rooting


I rooted my device because I have had to reset my device a few times due to problem with the contact synchronization.   Each time I had to reconfigure everything.  To reduce that need, I wanted to perform a full backup of the device without rooting.
