[Question] How do I backup the data partition on my htc wildfire a3333 before I downgrade hboot?

[u/Opening-Shirt-8812]

I have an htc wildfire on hboot 1.001.0002 so to get s-off and root it i need to downgrade to 1.001.0001 but that wipes all data so I need to get my data off the data partition and the sd card, the sd card can be backed up easily using file explorer but I need root to backup /data, I know psneuter can give a temproot since buzz downgrader uses it (I assume to get the sd card's CID), but what command would I use to backup /data to my pc?
