If I'm now on the 2.2 US Update with 2.2 Boot SBF, can I/how do I get back to completely 2.1 stock? I know I can unroot, but what about SBF/ROM/etc?

No I dont think you can downgrade from an official 2.2, besides there is no stock 2.1 US sbf you can flash to at the moment.. This is the closest to stock US you are going to get.
Wait - I have a Nandroid of my 2.1 stock. Would that do it or that would put me back in the same place as being stuck in a bootloop since now I have a 2.2 SBF?
u can restore it and after that 2.1 sbf boot only file
and learn to use search function ..or use faq ...more or less all your questions have already been answered ....no need to open a new thread for each trouble u ran into
and for your camera problem ull find an answer for that in jboogies bluerless ginger thread i had the same problem

I never saw an answer to this question. But I did see someone say that they went back to 2.1 after they were running the new leaked 2.2 ROM. I also recall reading somewhere that once the new radio is updated, you can't go back.
If I am currently running Froyo 2.2 with version 2 radio, can I just RUU, then run Unrevoked to restore root, and then restore my nand backup to go back to were I was before I started, which was Eclair 2.1 rooted with v1 radio???
No speculation please. I want to know if this is possible. Preferably from a dev or someone who has done this successfully.
Thanks in advance!
You're making this way too complex (RUU, etc.). Just nandroid back and you're good.
Will nandroid also downgrade the radio??

The OP stated that he wanted to go back to V1 of the radio. So if a nandroid restore won't downgrade the radio, then what options are there?
I believe this is what you are looking for.

My question is... if you do this Froyo 2.2 as in the developement area, because your phone is rooted when you are done, I don't think you will be able to get any further updates until you un-root. So do we have to revert all the way back to 2.1 or radio version 1?
I think I'll wait.

No, the OP stated that he'd "heard somewhere" that he needed to go back to V1 of the radio. I said he was making it too complex, just nandroid restore.
Really, it's that simple.
I forgot to nandroid after unrooting and installing the 2.1 ota leak. I am now rooted with the 2.1 ota leak and flashed the froyo leak. How would I go about getting back to stock?
So if we had previous 2.1 nandroid backups we can just restrore those? (while leaving the new HBOOT and radio of course)
I just want to be clear.
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 decide to update my radio and install a leaked froyo ROM is there any way to revert back to a stock phone?
Yes but not if you do unrevoked forever. Currently there is no way to revert s-off back to s-on. But you don't need to do that to run Froyo and an updated radio, and without it you can easily go back to 100% stock.
How would I go about reverting to stock? like if i want to return to stock 2.1 with original radio?
Just flash this zip file in recovery it will revert you to 2.1
Edit: ok it didnt take my upload for some reason the the zip name is PB31IMG.zip
oh so just reflash the stock 2.1 image and everythings back to fully stock?

I dont mess with my radio outside going to 2.x as for the rom which rom are you talking about?
Edit: Wait your stock 2.1 right now? If your asking about updating your radio so you can root and get froyo leak then just check out the videos from the guy I sent you above he has a video on updating your radio then just use Unrevoked3 to root
Currently I am running stock 2.1-update1, with a hydra kernel and s-off.
If I update my radio, am I going to have any problems with getting 2.2? Should I just wait for the OTA to come, and flash a recovery after I've installed it? If I do the radio update early, is my stock 2.1 going to keep working fine?
Seriously, nothing on this? What does updating the radio do other than allow 2.2?

I don't really know what your asking, and I'm sure that's why no one else has chimed in. But here is my best attempt to figure out what I can do to help.
To get the 2.2 OTA to install, you NEED stock recovery.
What I would do if I were you, and this is what I am currently doing -
keep S-OFF, un-root the phone by getting the stock recovery -
try this
androidforums.com/incredible-all-things-root/99828-video-howto-unroot-incredible-downgrading.html - sorry can't post links yet. cmon MODs! lol j/k
and then you'll be able to get the 2.2 OTA and then be able to put clockworkmod recovery back on and attain root.
"If I do the radio update early, is my stock 2.1 going to keep working fine?"
are you asking, will 2.1 still work with 2.15x radio?
to put it simply - yes,
but with s-off, what I used to do, if keep a file of both the 1.x radio, and 2.15x radio on your sd card, and if you want to flash either one, just move it to the root of the sd card and either go back up to 1.x or go back down to 2.15x radio.
Thank you, that actually cleared things up perfectly. Sorry for the foggy wording.
Can someone please clarify the following in relation to rolling back to 2.2 from 2.3....
If at any stage you need to revert back to a Froyo ROM, you will need to reflash /boot into CWM 2.X via Fastboot.
I get what I need to do to get a 2.3 based rom but dont understand exactly what I need to do to roll back clockwork to v2.5.?.? from v3 via hboot in case I have any issues
cheers
Open rom manager and flash away
