How to Downgrade to Froyo after installing HTC Stock Gingerbread

friend need help i installed HTC Gingerbread which the up on developer website on 1st of aug. now i want to downgrade it to stock froyo.
how to do?
help

Oh i dunno maybe if you put this question in the right place then yes it would be answers for you..
There is a Q&A section for you to put this question in don't waste developers time and mods time by putting your question here. you will get flamed just a fair warning I'm not mad just saying...

Dont think its possible Teppic74's downgrader wouldn't work on the ARA build, so doubt it will work like this.

You should had to ask this in your mind before flashing an RUU that contain an hboot update!

Go to www.shipped-roms.com and find the froyo RUU and flash it, it should downgrade your hboot and you should be able to root again. If you have a branded desire you’re going to need goldcard.
I you dont know how to Flash a RUU use the search function

It's reported to not work! The new hboot does not allow to flash an older hboot.

An S-off could have protected him. Have you tried the new AlpharevX to try and S-Off ur device? If it works, you can reverse the process later.

The new s-off tool wont work, it says that your device is currently unsupported.

Try their irc channel as well. It could be a 'soft' incompatibility, wherein they've disabled it because they havent yet tested it.
Is there no other rootable rom of the same hboot?

1. wrong section
2. every time the same, people will first flash and ask questions later

My downgrade tool almost certainly won't work on this. However, if someone manages to root this version, there's a good chance it will.

Paul Obrien did. Someone might ask him how to
he also flashed the hboot that came with the update.

If I not wrong, was a temp root anyway. But if Paul flashed the new hboot, this is a good news for those that flashed it too. He will of course find the way to change rom

I agree as well, but in the meantime there possibly are a few thousand Desire users who want this problem solved. Another possibility is that people who waited for the GB-update want to root after this disappointing update. They also might be potential donators (including me), so please get root for the official GB-update up and running!
Thanks in advance!

Hello mates, i'm having the same issue, just want to downgrade back to froyo and i can't do it because of the hboot . i've tried with unrewoked, went to shipped roms but nothing succeded.. can you please, tell me if someone managed to fix it ? thanks.

I know its frustrating but you will probably have to wait, keep an eye on the Desire Android Development section, I'm sure when theres a fix the devs will post it up there for you

I wouldn't read too much into that necessarily. A post on this forum thought I was working on rooting desire 2.3

[Q] How can I downgrade my DINC 2 from 2.3 to 2.2?

Hi,
Verizon is pushing out OTA updates to install Android 2.3. I'd like to downgrade to Android 2.2, and prevent the OTA from happening in the future. Is there a way to do this?
Cheers

Only if u are s off already.
Sent from my DINC2 in Yuma, AZ

Sorry, but currently there isn't a way. (with the exception of the xtc clip).
Hopefully alpharevx/unrevoked will get temp root on GB and allow s-off.

No. But you can do some searches and find out.
Please read/search before posting. Thank you.

I, too, was unfortunate enough to receive the Gingerbread OTA update with no confirmation or anything. The funny thing is that I clicked cancel after it downloaded it, which did nothing. What's even more funny is that this is replacing a previous Droid Incredible 2 which already had S-OFF and CM7.
For anyone trying to downgrade to Froyo using this method: http://forum.xda-developers.com/showthread.php?t=1033922 -- it doesn't work, so forget about wasting your time.

i dont know if you've read this thread already http://forum.xda-developers.com/showthread.php?t=1298990 but apparently it works, too bad im sorta new to this so i dunno how to do it myself xD if any1 is down to make a video or slide tutorial of how to follow these steps i am sure it would save the world for us inc2 unrooted users who want to root

it works, but its via adb only. Afterwards, using Revolutionary you can get s-off. The instructions are for downgrading to get s-off. Basically reverting back to .97 bootloader.

It does work, I used this method to downgrade today, i was able to gain s-off and flash cyanogenmod after. It isn't the easiest method for novices though. But the instructions are pretty clear. I had problems running the automated script included (i was in debian linux, so i cant speak for the windows script). However when I executed the commands in the script manually, everything worked . I would imagine that someone will package this method up nicely before too long...

[Q] What RUU for HTC Wildfire?!

Hey guys. I want to go ahead and start the process of rooting my HTC Wildfire, but the problem is, the current Revolutionary build supports only the 1.01.0001 HBOOT version. Mine is (you guessed it) 1.01.0002.
Luckily, HTCDev.com has finally launched their Bootloader unlock process that seems to be considerably easier than using GoldCard (http://forum.xda-developers.com/show....php?t=1145035).
Problem is, when I get down to the RUU download list on the first page of instructions, my carrier isn't there (I currently live in Malaysia and use Maxis). There is, however, an HTC WWE RUU at the bottom available for download.
A little help guys, cause I'm VERY new to this all and would REALLY love some help on what to do.

Yep understood. Well I just wanted to make sure to know that other method (or not). There will be a bit of risk left with all methods to root, s-off, debrand or flash a device - so the only helpful thing might be experiences of others...
That's a point where I probably could be of some help: people unlikely will come back with success stories, most likely they will post errors and problems- so here is my report: I haven't had any issues, problems, hassle with the gold card method (the thread you were pointing to) and I am not a developer, programmer or other kind of a "pro" plus this has been my first experience with rooting a phone.
what I should mention: I've been in the same dilemma: that gold card method did sound complicated and the reports feared me a bit, too ;-)
There's one thing I'd suggest either way: I did follow the instructions carefully - step-by-step, after reading them carefully - twice at least and I've kept an eye on all warnings.
Regarding the other method: if I would have to choose between the two methods I most likely would do the gold card method again. Because it worked for me - sure - but after reading the respective threads, e.g. this one I would feel more safe to do it the hard way ;-)

Run an RUU for wildfire.

- This downgrads phone OS to eclair (android 2.1)
- Let it do the bizniss

glad to hear that everything went well - as I said before: the risk is yours I could only tell from my experiences...
Regarding your question which thread I meant: yes, this mainly has been the source I tried to follow. But as I mentioned before I did read a lot (also in German...) and tried to collect the useful stuff and kinda sorted it later - prepared all hints for troubleshooting etc.
It's always a good idea to do so. If you have any serious doubts they most likely come from missing knowledge - so best idea: read even more ;-)

Some users are complaining about the aahk...it's bricking their dhds so i found that the safest way was to do the original steps like i rooted my phone and many other dhds without a single problem... i was just tryin to help ....and abt the aahk do you really recommend and do you guarentee that it works on all versions of dhds or just the new ones i personaly never tried it ?

It works on all versions of the dhd. I've yet to see one where it doesn't. The ace hack kit does not brick anything. Its just people are to lazy to read and properly setup their PC's for the kit to run. Plus they have an irc room to help people out yet "mysteriously" they miss that to even though its in the op.
To add what agoattamer said, eng soff is not needed but if you really want it the hack kit has a new feature to install it. Do not use any other tool as newer dhd get messed up when using older methods that are incompatible

[Q] I have a few questions. Hope someone can help?

Hello there,
I am new to modding android devices so i just have a few questions to ask about my HTC Desire HD and installing (flashing?) the JellyTime (ROM?) software onto my phone.
I've read through lots of posts but there quite a bit of terminology that gets flung around which im not understanding but i think i know what i have to do.
But my main question are, since I'm running Android 2.3.5 Sense 3.0 rooting my phone has become quite hard for me as every program i look at says I need to downgrade. I read [How to] ROOT without the Hack Kit and I'm guessing "IF YOUR BUILD VERSION IS NOT SUPPORTED TO UPDATE THEN:" applys to me.
But when i go to this post i have no idea whats going on or what a gold card is or what its supposed to do.
So as im a complete noob and i have sort of tried on my own i was hoping if anyone could lead me through what im meant to do to get my Stock DHD to the stage where its running JellyTime android 4.2.2?
I also found a download for AAHK which has been removed by its developer as far as i know and i dont know what XDA's rules are if i was to repost the download link. The problem with the AAHK is that its requires a downgrade of my phone and when it tries to do that it needs to download a RUU(???) which was hosted on the developers site which is now removed and it returns errors for the RUU

What does make you think that your build is not supported? The hack kit is retired and unsupported, are you going to repost and support a tool that might leave you with a brick? Even you have all the files needed by the kit to work?

Because the program in your root guide said that my software version is not supported, I have skimmed through the guide and I will read it properly on the weekend.
Why would it brick my device it has worked on all the device that used to use it? as I have read it used the be the go to tool for root and S-OFF. I thought the developer just didn't like the scene anymore are removed all his work i thought i still worked but the downloads where hard to find.
Could you please tell me if i can run JellyTime on my device?
Also reading your guide i didnt understand the information about rooting where you talked about S-OFF wont be needed to run CWM recovery as i read somewhere that CWM recovery needed to have S-OFF to work.

It hasn't worked on all the devices. It was the go-to tool for S-Off, but read back through the forums; many people (usually those who did not read well) have run into problems and needed support. And if you post it for others in a responsible manner, you need to support that possibility.

My phone says my build(ROM) version is 3.12 but the hboot program says its 3.13
the root kit wants me to update but the ROM updaters says updating from 3.13 to 3.13 but the phone still says 3.12 ????
__________________
I ran the ROM updater outside of the ace root kit. Now it realises that the ROM is still 3.12... But not when i try to update the ROM it returns error 191????
Thanks for the help

I used the HTCDev procedure to unlock the bootloader (updating my hboot to the .29 version going from the .27 version), I then installed CWM. From there I flashed a CM10 ROM selecting the zip from the SDcard in recovery, then the last step was running the command "fastboot flash boot boot.img" after extracting the boot.img file from the ROM file.
I have no real use for root or anything, I just wanted jellybean, and it's well worth it.

Install download oneclick root and your problem will be solved.

Read the Ace Think Tank linked in my signature. You are not unlocked, but you can use the Tank-linked Easy Ace Root Tool to do so. As for a tutorial on flashing custom ROMs, the Think Tank has links for that too; no need for a separate walkthrough reinventing the wheel.

Hi yeah as talked about above and in another post i have use the easy ace root tool but it requires me to upgrade my hboot and/or software. I'm running software 3.12.405.1 but I need to be running 3.13.000 apparently. It automatically downloads HTCDev's RUU but every time i run it it gives me the error 191 ROM not supported.
I have tried all variants of the RUU from the HTCDev website for my phone even for the wrong carries all give the same error.
I read somewhere that i may need a Goldcard since i carried out an OTA update on my phone and its tied to an orange (ee) contract?
However the goldcard generating website is now offline due to hackers and they said they are shutting down and the only person i could find who said they could generate goldcards (geene pool) isnt responding to my PM.
so I'm all out of luck.

Ah. Then yes, you are just out of luck. I know that there's a way to generate a goldcard yourself instead of having Gene Poole do it (I believe by using a specific ActivePerl version, a specific Crypt SSLeay module, and the goldcard generating script) but I haven't had the inclination to do it myself. If you really want it you could give that a shot.
