[QUESTION] How to Downgrade Stock 2.2 to Stock 2.1 - Desire Q&A, Help & Troubleshooting

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.

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.

[Q] Anyway back to 2.1 or root 2.2 updated?

After just getting my Evo recently I was overly anxious to get Froyo so updated it quickly not knowing that standard rooting methods wouldn't work on it. I was wondering if anyone has found a way to go back to 2.1 or a way to root the 2.2 to install custom roms ect...?
......wait for it......
eeeeew. Who wants to do that?

[Q] custom rom to official 2.2 rom (how to)

Hi all,
I have a HTC Desire A8181, SLCD, hboot 0.83 with AuraxtSense 7.4, its umbranded and not simlocked. I would like to install STOCK 2.2 (RUU_Bravo_Froyo_HTC_WWE_2.10.405.2_R_Radio_32.44.00.32U_5.09.05.30_2_release_142828_signed.exe)
Is it possible to simple execute .exe or i have to do it using other way? which way?
Thank you,
Marcello
Moved to Q&A. Please don't post question threads in Development.
Yes it is possible to just execute it, and it will guide you through the process.
There is other ways if you can't get it to work but start with the ruu
i second that. if you want to go back to stock unrooted rom, flashing a RUU is an easy way of doing that. but if you want other ways. you can try this one.

Upgrade a 2.1 Rooted Evo to Froyo

I tried searching on this and closes match I could find was this:
http://forum.xda-developers.com/showthread.php?t=743352
However, that refers to a "Leaked" Froyo firmware. What I'm trying to do is to upgrade my already rooted 2.1 Evo to Froyo (2.2) and then root that of course
If I try to do a OTA upgrade automatically through the phone, I get an error. Anyone advise what the best method of doing the upgrade would be?
Maybe try this -

I had stock 2.2 with the latest OTA and rooted it. It was very very simple. Here's the link-

Hah. Very interesting question. Ok, so rooting lets you change the system as well as the other partitions. Froyo and eclair are both system changes, so try flashing a froyo rom. Didn't you research before rooting?
Yep, you're right. I'd blame it partly on being 1 AM and partly for not thinking it through. Thanks.

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
