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.

Updating OTA After Root

My first post here
Ok so I rooted my HTC EVO with Unrevoked and loved it. Everithing is working just fine. Lately I am getting the OTA Update request but I denied it since I read I could brick my phone. I found on this post http://forum.xda-developers.com/showthread.php?t=874251 what I think i need to update the OTA but dont know the difference between Deodexed Version and Odexed Version... What do I need to use or do to Update the OTA...is it different than rooting?? Thanks for your help!
Software 3.29.651.5
Android 2.2

Just flash a rom. Most available now are based off the 3.70 ota. Deodexing is process that allows for easier theming. Odexed roms will boot up faster and are basically completely stock.

Yup new rom flash. I'd you like sense I suggest myn's warm twopointtwo, but for aosp you can't go wrong with cyanogenmod. Look around a bit. most all round come deodexed these days & I would suggest it. Odexed is apparently not notoceably faster, but I can't say since i've never used an odexed rom. Deodexing is basically taking all the framework files & making a new path for them. Correct me if I'm wrong

Thanks for your replies, i really never tried to flash new roms in my phone since I dont know much about it but I will read around...what king of guidelines you can use to select the ROM you will use since y see there a lot of different around

[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).

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

[Q] Downloaded 2.3 Gingerbread

So I joined the whole "impatient and I can't wait" boat and decided to download the new 2.3 Gingerbread from the "HTC Software Update" option in the settings tab.
I just completed the download and clicked on "Install Later." Now the download is sitting in my notifications bar for whenever I decide to install it.
After browsing the forums and hearing raving reviews of those who have rooted their EVO 4G (and hearing that you cannot do it on an unrooted phone running 2.3), I want to stick with 2.2 froyo and root from there.
However, the question is, can I root it with the downloaded 2.3 sitting in my notifications bar? After I root it, will the 2.3 notification still be sitting in that bar just waiting for me to accidentally click it and screw up my phone's root? How can I get that notification out of the bar because I don't want to install it anymore and all I want to do is root my phone...

All that means is that you have downloaded the update and its ready when you are. You can clear the notification and it will still be on your SD card ready to install if you ever choose to. The notification just tells you it has been downloaded and nothing more. Welcome to the XDA and enjoy rooting!
Goodluck!

And props for doing the research BEFORE you installed the Update!
+1

I'd suggest rooting now. Use unrevoked, it only takes a few minutes. Even if you were to accidentally install the update, unrevoked forever should keep you s-off, so all you'd have to do is reflash recovery and you'll be set.
Although, if you do go ahead and root, you might as well go ahead and flash a custom rom. Find one you like and you'll never want to go back to stock again.
But if you decide rooting/flashing isn't for you, you can always unroot and go back to stock.
EDIT: And agreed, good job on actually reading first. You're officially smarter than at least half of the already rooted people on here.

Truth is, if you really want the benefits of the GB update, Android 2.3.3 plus Sense 2.1 with 3.0 mods, just flash one of the Gingersense ROMS. I can endorse the one I'm using, Mik's 1.01
You'll be MUCH happier than a stock EVO with GB 2.3.3 and Sense 1.0

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

Hey dude.
Here is the link to AAHK http://forum.xda-developers.com/showthread.php?t=1259821
Hope that helps.

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
