Help\How to downgrade Gingerbread 2.3.3 to Froyo 2.2.1 on HTC Desire A8183?

    Was just wondering if anyone knew how to do this?
    I'm not fussed whether I have to root the device or not, I've got a bit of experience in this, just not quite enough to work this out, I've found so many Gingerbread downgrade guides for just about every other make of android device, just not my own.

    My reason for wanting to downgrade is that I can't root via unrevoked and flash Amon RA Recovery because unrevoked only currently supports froyo.
    Another thing, no matter what I do, my SD Card will not mount, meaning I have to do everything straight from my computer to my Desire.

    Any help would be greatly appreciated.

    Device: HTC Desire A8183
    Carrier: Telstra
    Country / Language: English / Australia
    OS / Browser / build number : Gingerbread 2.3.3 / Webkit-533.1 / 3.14.405.1 CL96875 release-keys

    all you needed to do was read our guides.
    2.3.3 cannot be rooted by unrevoked. however there is a tool called revolutionary that will s-off the device and then you can manually flash amonRA via fastboot.
    once this is dont you can do 1 of 2 things, flash a rooted rom of choice or root the current rom by flashing the superuser zip file onthe unrevoked wiki page

    Could you please refer me to an appropriate guide? I looked, but had no luck finding a suitable guide for my situation.
    I have already 'S-OFF'd my phone, if that helps.

    All out guides are linked in the sticky thread "All about rooting". You're looking for the one with "revolutionary" in the title.

    if youve already s-offed you phone im guessing you used revolutionary
    did you read their wiki on flashing super user. they give you the file to download.

    all you have to do is download amonRA 2.0.1 from our tools thread and use fastboot to flash it

    there is a fastboot faq showing you how to get and use fastboot correctly

    we urge people to read through all of the guides as suddenly everything falls into place and you will become and instant guru

    i aint lying either

    just did what you said, Rastaman, worked like a charm, thankyou.

    also, is there a way to root my phone? all the guides I've seen have all suggested the use of an SD Card, still currently running Gingerbread 2.3.3, soon to be CM7.

    Please just read the guide in the "All bout rooting" that I have already mentioned!

    as stated above, in "our" guides, no one elses we go through all eventualities
    I also mentioned on this same page that if you just want to root your current rom, you download the superuser zip (su) from the revolutionary wiki and flash it from recovery (after taking a backup)
