anybody now to downgrade 2.2 back to stock 2.1, i found som info but refers to the nexus 1. it advices to unlock the bootloader by flasing a .zip file (goto androidtechnical.info and get the passimg.passion_.zip file load it to your sd card root name it passimg.zip (just one zip ext) and flash wahla)
I was wondering if i can apply this to my EVO and be done with it?
just flash to 2.1 rom.
whats your reason?
Downgrading will only be possible once it has been determined how to root an unrooted 2.2 EVO. That is not possible, at-the-moment. We will just have to wait....
if you aren't rooted currently there is no way to downgrade or root 2.2.
so in short you are stuck at stock 2.2 until the amazing devs figure out a new bug to exploit to provide root.
but just to confirm, if i'm rooted since day 1(original 2.1 root) and i installed a rom from XDA(OMJ's 2.2 froyo) i can downgrade simply by installing his older 2.1 rom right?

Not sure if you can flash a 2.1 OMJ over a 2.2 OMJ (or similar) becasue I haven't done it ( I don't think you can), but if you run simple root again (or do Toastcfh's part 2 manually) and load the engineering build, you should be able to again flash a 2.1 to downgrade...Same idea as what you need to do to downgrade in order to flash a RUU if you have to send your phone back for any reason...

i tryed that, Froyo locked up my bootloader. I have too many issues with 2.2 for my taste. I want to go back to a rooted 2.1 and flash a custom Froyo Rom

yes! this is what I want to be able to do. having an original 2.1 root allows you to flash any ROM Sprint Stock or ortherwise, its almost like changing skins but your base never changes. The only time things change permanently is when you do an UPDATE. Doing an UPGRADE only brings the eye-candy that only a custom ROM can provide.
If I downgrade my HBOOT from 0.92 to 0.80 and root it and install Clockmodrecovery.
Can I download the original HTC Froyo ROM from the sticky thread with official RUU ROM's and flash it?
No. You don't root a bootloader. If you install the official ROM, it will remove root.
Okay thanks.
I see you're looking after the same as me, take a look in this thread. It's the official 2.2 rom with root access

That is a custom ROM, not the official/stock ROM (it's just very similar).
Hey guys,
I have rooted Desire 2.1 with the stock rom.
Now, after HTC released the Froyo to asia, I would like to update to it.
but I have some questions :
1.to unroot and than do OTA for 2.2, I only need to install the RSUU right ?
2.will I have to root the 2.2? is there a root for it? ( I have bootloader 0.80)
Thanks !
I have just installed Oxygen on HTC Desire, but I prefer official 2.2 android.Is it possible to downgrade?
Yes, either flash a 2.2 rom or if you want go back all the way use a RUU.
Will installing the new 2.3.3 ROM for Desire from HTC (http://htcdev.com/devcenter/downloads) remove my root/S-OFF? Or should I go with something like this instead of the official one: http://forum.xda-developers.com/showthread.php?t=1040121
you don't install the update 2.3.3 because this rom is for developers, and remove root because the hboot change to 1.02.001. If you want to have root install rom
Just use this one. http://forum.xda-developers.com/showthread.php?t=1200261
It's as close to stock as you can get and it's rooted and still allows S-OFF
