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.

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.

can you please provide the link?
My bootloader is .80 and software number is 2.09.405.8
Radio version is 4.06.00.02_2
That radio is an old one so I'm guessing you're on a custom ROM at present...if you were on the proper FroYo ROM you'd have the same radio as me (see signature)

how can I update the radio? The radios I have found needs rooting before upgrading. and my froyo cannot be rooted.
If you're on FroYo you should be on the radio I'm on as 720p doesn't work with the old radio - which is why I asked if you're on a custom ROM. The new radio is on the OTA update and should be installed as part of the update
If you use an official update you will get the latest radio (5.09.00.20), the latest software (2.09.405.8) and the latest bootloader (0.92). It isn't currently possible to root this.
If you're running 1.x software (i.e. Android 2.1) you can root the phone and install a rooted Froyo ROM and the latest radio. This is the only way at the moment to have Froyo rooted.
If you have upgraded to Froyo without rooting and have a 4.x radio, something has gone wrong with your update.
thats what i did, rooted 2.1 then updated radio to froyo radio then used a stock but rooted 2.2 with hboot 0.80 from macado.

you are right. I upgraded to froyo without rooting and stuck with 4.x radio. the Rom is working fine except I cannot install any application from android market or from pc. what can I do now? even if I can go back to my 2.1 Rom, that will be fine with me. please help.
If you don't want to root then you can just apply the Froyo RUU:
http://shipped-roms.com/shipped/Bra...3.00.32U_5.09.00.20_release_140022_signed.exe
If your phone is branded you will need a goldcard for that to work.
Right, now we're getting somewhere!!
Where did you get the Desire in the first place? You'll need to find the RUU for the ROM your phone originally came with
All ROMs can be found here:

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
Hey Guys I just did the Froyo Downgrade onto my Desire Z and some of the apps I use just can't run on Froyo... I have the system update to Gingerbread android 2.3.3 with HTC Sense 2.1 and I want to go back to Gingerbread....
Is it okay to install the Gingerbread update?
well if you want to forget about obtaining root access and s-off that is possible only from froyo then you may update to gingerbread.
Else you can go and follow the rooting guide to obtain root, s-off after which you can flash custom roms of your choice i.e, Froyo/ Gingerbread / ICS
