is there no other way than losing my OS?
even if I root it after getting it to 0001, can I revert it back to HBOOT 0002 & Froyo 2.2.1?
For Wildfire downgrading your hboot is a must if your going to follow those instructions, you cant root with hboot 1.01.002 because of HTC. When you downgrade, yes your OS will be the same but then later when you use the RUU, you will downgrade your OS to Android 2.1.
Well if you think about it there is software available so you can backup various data like MyBackup
for contacts, calender, apps, alarm settings, bookmarks and others, and you can use GoSMS
for backing up your text messages
Which you can all restore after you've finished rooting.
Yes you will lose all your data on your device but your sdcard will be safe.
If you want your old hboot back, then that means losing all your root privileges and going back to your original phone (without the data)
If you want Froyo 2.2.1, then you can still have root but you have to flash a ROM that has Android 2.2.1
