As of right now there is no possible way. But give it time.

i'm looking to downgrade as well if anyone hears of anything!

I was reading about someone downgrading their nexus one froyo back to eclair using andoid sdk and some rooted sign file and a recovery file. Lucky nexus one users lol.

Anyone know anything about this?

if you want to downgrade then wait, it took a long time to root the last OTA.
If you want to upgrade and keep root, NEVER accept anything from sprint, only install from XDA or a similar forum.
The fact that this is an entire OS upgrade can either be a good or bad thing in how long it's going to take to root.

Look at it this way: If you could downgrade to 2.1, there would be no warnings or questions about how to root after flashing the 2.2 update. The answer would be "downgrade to 2.1 and root it like before."
But once 2.2 is rooted, you will most likely be able to flash a 2.1 stock or custom ROM if you wish. Just make sure you flash one that's pre-rooted.

Thanks for all the info guys, I wanted to downgrade to run cyanogen mod and overclock etc.

OTA Froyo 2.2

http://community.sprint.com/baw/com...rd-winning-htc-evo-4g-beginning-tuesday-aug-3
I'm at a loss, as I remember reading it but can't find it any where to verify. When Sprint releases 2.2 Aug 3rd, since I'm rooted I should NOT accept OTA or force it to update...or ever do it, right?
Sorry for the dumb question, just wanted to make sure!
You should not.
thanks for the quick reply!
hi im using unrevoked3, how do i go about updating to froyo 2.2 when it comes out OTA? thanks!!
you dont until someone here roots it.
And go ahead and get off unrevoked now. Do a full root and use a rooted rom even if its a stock rom. You will be happier in the end. There are several methods posted in the Dev forum. Just pick one that matches the sweet version your currently running or follow the instructions posted previously in this forum.
Actually, I don't recommend full root if you can get by without it. Full root permanently screws up your PRI, even after unrooting. Until its fixed, people should only do it if they absolutely need it. You can use an ota update, but you will lose root until someone finds a way to root 2.2. Also, you can flash one of the stock 2.2 roms that are rooted. They should work with unrevoked.

It doesn't screw up your PRI, it just makes it a lower version. For some people this causes lower speeds on 3G; others are fine. But yes, once you do NAND unlock your PRI is stuck like that until someone figures out a way to update it.
I think flashing a 2.2 ROM with unrevoked and expecting it to stay rooted is a risky thing to do. I wouldn't recommend it personally. That is, unless someone has tried it and it works.

[QUESTION] How to Downgrade Stock 2.2 to Stock 2.1

I have been looking around for a while for a solution to my problem but i cant find anything concrete so my last resort is to start a new thread so please bare with me.
I installed 2.2 Stock Froyo with HTC sense on my Desire and I would now like to root my phone. My understanding is that I have to go back to 2.1 in order to do this. Is this correct? Then once I am on 2.1 again then I can Root my phone. So my problem is in 2 questions:
1) Do I need to downgrade to 2.1 in order to root my stock 2.2 desire? If not, what recovery image would I use to root?
2) Otherwise If I do have to downgrade to 2.1, what is my best solution?
Thanks in advance.

[Q] Wondering if anyone has Rooted Stock 2.2?

Hey I'm just wondering if anyone has successfully Rooted Stock 2.2 for the Incredible yet. From what I read, I think Unrevoked is currently working on a 1-Click Root method for the people that received their stock 2.2 update.
The only reason why I am asking is cause I've always wanted to install CyanogenMod's Rom on my phone, ever since I heard they were working on working all the bugs out and whatnot I've been wanting it on my phone.
From what I understand the latest build of Cyan includes 2.2 and is somewhat stable and only a few issues exist which are supposed to be easy fixes.
But in any case I guess my question points to two parties: Unrevoked and Cyanogen - I need one group to make a compatible Recovery and the other to make a compatible ROM and without the necessity to include the 2.2 update. For those of us that already have the official OTA.
I hope this isn't asking/expecting to much. Anyways if anyone has got any information on the progress of either project please let me know. Thank you!

Yes!!
did it the first day I got the 2.2 notice...here is a post...
http://forum.xda-developers.com/showthread.php?t=771178
I am stock 2.2 rooted with unrevoked clockworkmod (manually) and S-OFF must be set....see link...
Oh...you can install a different room but get the device setup first but you will need S-OFF....very important...
Ya here's the problem with that method...I do not wish to downgrade. And I'm really against the whole wiping my phone idea cause even tho I know backup apps are available they never really restore the app fully and usually all the update links to the marketplace are cut. I'll just wait for the 1-Click method from unrevoked. Thanks for replying but you kinda missed my point. I wanted to ROOT and install the custom ROM with the stock OTA without having to downgrade cause I hated 2.1 with a passion.
Ya so I guess to simplify my question I'll just rephrase it:
Is it possible for me to use the CyanogenMod on my phone if I already have the stock 2.2 ota installed? And I think you just answered that question, because you said I would need to have the S-OFF first correct?
i'm rooted with 2.2 stock too!

Right now the only way to s-off is if you were rooted before 2.2. There is no root available for group yet. There is a guide to downgrade to 2.1 then root and s-off, but if you don't want to do that then you are stuck until they come out with a way to root 2.2.

Thank you for answering my question.
Even tho I never really cared about S-Off all I wanted was to install the Custom Rom.
unrevoked from Twitter:
Making good progress on v3.2 of unrEVOked right now. More devices, FroYo across the board, integrated optional S-OFF!
^^ just wait

[Q] Root Desire HD OTA update gingerbread 2.3.3

hey guys.
did anybody know here how to make 2.3.3 ota update root, i have tried gingerbreak that doesnt working showing just black screen.
my phn is s-on, I do it coz it wont accepting OTA update.
is there any manual process to make it root via adb shell or something like that.?
i dont want to install custom roms i already checked so much of them but the are not fully bugs free and not fully google compatible as i want..
It is not possible. True, not all the ROMs work great, but some do. Try Android Revolution HD 5.1.6.
You have to downgrade first to get root, and then S-OFF if you want to flash custom ROMs.
You can also downgrade, root, get Radio S-OFF, unroot, get OTA again and use GingerBreak. Then you can have root in the latest HTC Gingerbread ROM.

OTA didn't came when radio is S-ON. thats y i did this..
Your phone is always S-ON when it is stock, so surely OTA will work then. And even when it is S-OFF, it does not matter if your /system partition is in stock condition (no root, no bloatware removed).
HTC have stopped Gingerbread OTA because of to many bug (To many have reported problem with SMS, WiFi a.l.). It will be released new version within few weeks when those thing is fixed. Ref HTC support
Thanks jkolko for the useful s-off & eng-off guides. Should anyone else find it an issue, note that if recovery cannot mount your sdcard, you should try another sdcard (found this elsewhere in the forums).
Hi, any app for downgrading? Honestly, not à "hero" when it comes to touching my phone, but would like root (at least to get rid of some stock apps).
Sent from my Desire HD using XDA App
To have root in 2.3 you need to use the downgrade guide to 1.32. Root and S-OFF and update to Gingerbread using 2.3 RUU. Then use Gingerbreak .apk to root. Now you have rooted S-OFFed Gingerbread 2.3

Updated to 2.3 from fully rooted 1.32 by RUU, installed AMT and now have su and full root Gingerbread AMT relay works, thanks to developer of script...
Hello Frendz,
The day before yesterday HTC sent an upgrade to the factory default OS (i.e. 2.2 froyo) on my DHD and I happily upgraded to 2.3 Gingerbread. Now, before updating I had permanent root access on my desire through Visionary but just after the update I realised I do not have root anymore. I would appreciate any comments and other experiences in this matter.
Also, during my own research I came across Gingerbreak which is probably the best around for rooting the 2.3 version but all I wanna ask is, if I still need to downgrade to gain root access or is it possible to directly use ginger break somehow? If I am not flashing another Rom, and all I want is Superuser rights.
As, I have never flashed any other find on to my DHD and I was using the stock interface since the start obviously with visionary root.
Also, whichever way I do it, I would loose all my contacts apps or we can avoid that. Can anybody please suggest any good (possibly free) backup app.
Tooo Long to read but any help and replies will be greatly appreciated. Thanks in advance.

Anyone have any idea when Visionary or another One Click will work on a stock DHD running 2.3.3? I only want to root to get Set Cpu to improve my battery life.
You can trust my word.. Never.

Wow, that's a bold statement in tech lol
Any reason why this build will never be hacked when seemingly every other one is?
Not doubting yr word at all tho lol
Because it uses (as far as we know) pretty much flawless security measures that prevent us from doing much anything. Previously the devs found a way to go around the main security barrier after two months of trying, and now HTC blocked that security hole. As downgrading is possible, there are really not much interests to try and crack the new builds. Especially as it seems like a mission impossible.
....sigh.....
and since downgrading, gold cards etc etc is not my favorite, still waiting for a simple apk "for dummies", I guess I can forget to get to root mine.....
Those guides are really not so hard. Read them a couple of times, and if you still do not get it, ask your friend to do it. You can also join #AndroidRevolution IRC channel, somebody can hold your hand through the process. If I am logged in, make sure to send me a private message in IRC so I notice you.
thanks for the offer! will read again & probaply come back t you for help
Indian Desire HD
Apparently the Indian DHDs running 2.3.3 cannot be downgraded to root.
Any help would be appreciated.
Thanks
You can install seraphic custom Rom if you like its just a stock Rom with stock kernel and root access. I love that Rom, closest to stock you can get on rooted DHDs IMO.
yes, it really sad that to say 2.37 OTA upgrade cannot be downgrade this time, I really want to downgrade or just root it :'(
nothing can do this time

How to root it? HELP!

I am tired of watching useless YouTube videos, reading useless comments, and doing it from November until today. My Desire HD is updated, as you all DHD users know, the latest update is the Sense 3.0 update, and now it's a 2.3.5 ver. Android on it. The question is? How can I root it?? I REALLY want to root this phone but I couldn't find a solution for 2.3.5 Desire HDs, just the Froyo ones. Help please! I tried GingerBreak, SuperOneClick. Nothing happens, they run forever and do nothing.
Hey dude.
Did your DHD come with Gingerbread or did you OTA update to it?
If your DHD came with Froyo and you updated to GB, you can factory reset your DHD to take it back to Froyo, then follow the instructions here to downgrade to 1.32 then you can root etc...
Regards.
Greg.
Thank, it came with Froyo as I've bought it when came out.
You can use AAHK (advanced ace hack kit). Search for it on the site. It is updated to root all versions of Android officially released for DHD. No need to this manually as the AAHK does it all on its own in mere minutes. Just make sure you really read what needs to be done before running it. It really is a very simple process. If you get stuck running it, AAHK has an irc support chan so you can ask there or in the thread directly.

Donno if I am missing something but i cant find this AAHK thing, and the factory reset does not downgrade my phone, just removed all my stuff, but still 2.3.5 and sense 3.0. Why is it so complicated...
Use search in xda. Aahk will find the thread.

I found Jkoljo's method easiest. One click root s/off Downgrade , then root. Easy as 1,2,3

Hi there,
I'm in the same situation as the TS, also with the stock OTA Gingerbread update. So, I understand that a downgrade is unavoidable during the root process right? I understand that AAHK is the way to do it. My question is, will it OTA update back to my current version of GB 2.3.5 with Sense 3.0 after the root and downgrade? Or is OTA updating after this process dangerous or will it undo the root? I'm kinda guessing that flashing the stock 3.12.405.1 ROM manually will undo the root process?
I know there are probably many magnificent ROM's out there that I could flash. But I just don't have the time to identify the differences, try things out and maybe change to another ROM because of bugs. I did do that back in the old WinMo days. Then I would probably flash a new ROM weekly, because there was something faster or more bugfree. Because, even a ROM from the greatest chef has some bugs. I don't have time for that anymore unfortunately, so I'd like to stick with the stock ROM which is good enough for me.
In fact, the only thing I want is root, in order to control permissions from apps (Permissions Denied app) and make better (Titanium) backups. I want nothing more.
Please help me out!

You could OTA update back to 2.3.5, but you would lose root! ;-) Here is a pre rooted stock ROM you can use after rooting: http://forum.xda-developers.com/showthread.php?t=1382235
