To root the 2.37 update will it not be possible just to turn the appropriate carrier froyo rom into a .img file and flash that via the bootloader, then downgrade to 1.32 and root (just curious although my DHD is already rooted).
[Desire HD Android Development] jkoljo:
Sure you can, but you can only do temproot, then you have to do some manual setting up.. It is not really a solution. If you are too lazy, then don't do it :)

No, because Desire HD also checks the software number, and it does not allow us to downgrade to lower version number (i.e. from 2.36.abc.d -> 1.32.abc.d).
[Desire HD Android Development] thenocturnalnurse:
By any means, is there still hope that the current firmware version can be downgraded? *fingers crossed* :D
[Desire HD Android Development] jkoljo:
Sure there is, it is just a matter of time :)

If I already have S-Off on 2.37 am I able to downgrade?
[Desire HD Android Development] fshami:
Ofcourse you can. Read the first thread of this amazing guide ;)
[Desire HD Android Development] ZeTa18:
I´ve done all of the steps of this guide and i got and error, when i put adb shell i get $ and not # i tried the steps many times and i get the same result ¿What i doing wrong? im supercid (11111111) and i got the S-OFF, Pleasee Help me...

FAQ:

Q: I have done Radio S-OFF and SuperCID, do I need this?

- No, with those you do not need this kind of trickery.
[Desire HD Android Development] ZeTa18:
I don't know what do you mean with this comment... I got supercid with a Imei unlock and I don't know why I don't get root following the steps.
[Desire HD Android Development] jkoljo:
He means that you should read the FAQ before attempting incorrect things with your phone.

Yep, just throw the PD98IMG.zip into your SD card and reboot to bootloader. Easy.
[Desire HD Android Development] ZeTa18:
thanks a lot, i dont understand the comment so sorry for that, i will try now!! thanks for yours quick answers.

The last answer, I'm supercid, but not root, it's doesn't matter? thk
[Desire HD Android Development] DominatingSystem:
Can anyone tell me whats wrong here ?

I Have Android 2.3.3 and Version 2.36.405.8.

I follow the Instructions but fail everytime :/
[Desire HD Android Development] jkoljo:
Give it time, reboot, or do a factory reset. Usually one of those helps. Also make sure that you have disabled any antivirus software before downloading the downgrade zip file.
[Desire HD Android Development] wickedsaint:
Dear jkoljo,

Will it take a lot of time?? Cant really wait to install the wonderful custom ROMs that developers put up here...!!

I checking this thread and yours almost thrice a day!:(
[Desire HD Android Development] jkoljo:
I honestly do not know. The earlier root-blocking update got cracked in two months I think.
[Desire HD Android Development] :
Oh right, thanks for the reply
[Desire HD Android Development] thenocturnalnurse:
IMHO 2 month's fast for a tough job :D
[Desire HD Android Development] strusiu:
error when you type these commands

anyone know what's the problem?

build number: 2.36.405.8

//edit

Factory reset helped :D
[Desire HD Android Development] sidon100uk:
I am running the DHD 2.2.1 update and i am wanting to downgrade i have follow everything but when i do for froyo i do not get a # i get $ but as the guide suggests i did the Gingerbread cmd and this worked but with the goldcard i have made all i get at bootloader is CID incorrect.

Please can someone point me in the right direction, when i made my goldcard for my Hero i had no problems.

Thank you in advance.
[Desire HD Android Development] jkoljo:
You probably did not do the goldcard properly. Try it again :)
[Desire HD Android Development] tmh:
Just wanted to say thanks for this great tool and guide :-) Got my DHD back from repair today and of course they had updated it. 10 minutes after receiving it, I was downgraded, thanks to this :-D
[Desire HD Android Development] sidon100uk:
When i make my goldcard the txt goes red until i save is that correct?
[Desire HD Android Development] jkoljo:
Just follow the instructions, yeah I recall it goes red. I am not 100% sure though, because I only made a goldcard once for testing purposes. My own device is carrier free.
[Desire HD Android Development] sidon100uk:
I have just tried it again with another sdcard and still same error. Tomorrow i will start fresh from the begining and see where i come up. Oh and should i use froyo or gingerbread for 2.2.1?

Thank you for your help.

Hi jkoljo.i'm a newbie to android system.unfortunately I update ota 2.37.i don't want to stuck in it.plz help to find the solution.i want to try many new cooked room out there and get my device rooted.sorry for my bad english

Hi from cambodia.one more thing is any one know how to install khmer unicode on android system? Cos my phone can't read cambodian website.
[Desire HD Android Development] jkoljo:
I do not think that anybody wants to be stuck in 2.37, but that's the way it is at the moment. You cannot do anything about it.
[Desire HD Android Development] hmpfbla:
Hi there,

I tried to downgrade from 2.3.3 but Im stuck after executing the GingerBreak.

CMD window shows

After that I only get the blinking cursor. Even after waiting for up to an hour it wont change.

Additional information:

- Software-Number is 2.36.207.16

- Android Version is 2.3.3

- HTC Sync is installed and latest updates applied.

- Since its a branded DHD (o2 Germany) I created a goldcard beforehand and copied the PD98IMG.zip to it.

- CMD is elevated.

- Windows 7 x64

- No custom ROM installed. Its the vanilla HTC O2 ROM.

I did 8 factory resets and tried it several times after each reset: No change, it always stops at the same line.

Anyone got a hint where the problem might lie?
[Desire HD Android Development] jkoljo:
Hmm, that error happens when Gingerbreak has been patched to be disabled in a ROM. You could ask some other 2.36.207.16 users if they have successfully downgraded their software. The chances are that HTC has blocked rooting in your build, though. Then you are in the same boat with 2.37< users :(
[Desire HD Android Development] scorpion5:
Same here! Welcome to our boat :)

AlphaRev team has been working on temprooting the new builds, but it seems that they failed. I hope that the android exploit crew can cook something up..
[Desire HD Android Development] scorpion5:
OMG!!! They faild?

Now the only hope is the android exploit crew...:(
[Desire HD Android Development] thenocturnalnurse:
Let's not lose hope buddy :) I don't want to be stuck at this official ROM also. Just stay positive hahaha LOL :D
[Desire HD Android Development] DotNetRules:
Hi all, I have been working with HTC to find a way to sort 2.37 out. I was one of those that upgraded OTA to 2.37, since upgrading I've had a ton of issues with the device. HTC have gone out of their way to help, they tried to downgrade it, which didn't work as we already know, they even tried to reflash the current build with a matching RUU and that too failed......

So during all this I asked my carrier repair centre who I know flash these things as part of the repair process all the time, and I was surprise (or maybe not) to hear they have no way to reflash 2.37, so any 2.37 device that requires reflashing is stuck for now. HTC actually bricked my phone in the end after weeks of work, now I'm battling to get them to replace it, my DHD is only a few weeks old :mad:
[Desire HD Android Development] jkoljo:
Well if you have friends in HTC repair center, just tell them to get you S-OFF. HTC can Radio S-OFF any phone they want. Then you can come back here, download the PD98IMG.zip from the first post and reboot to bootloader. Depending on HTC's unlock method you may have to make a goldcard, but that's it. Your device will allow the downgrade.

A simple advice for anybody who is stuck, and is desperate to downgrade: send your phone to HTC repair center, with 50 euros and a note to give you S-OFF.
[Desire HD Android Development] DotNetRules:
Mate without a word of a lie they have tried and can't do it. They aren't my friends either by the way but rather I found a person in HTC that went the extra mile to help, we spent weeks without success. I have emails to say they can't do it. They even sent me their tool to try, which I'm told is the same thing they or a repair agent would use, still no luck.
[Desire HD Android Development] UpInTheAir:
Out of interest, could you please UL an image of the tool, if you still have it.
[Desire HD Android Development] jkoljo:
Same request here! Please upload the tool for us, mate :)

You have no idea how important that tool can be, it may even have the HTC's private key in it :eek:
[Desire HD Android Development] oranje:

[Desire HD Android Development] jkoljo:
Search button is your friend :)

In short, do a factory reset.
[Desire HD Android Development] jkoljo:
Lol, he just used the same hack my Radio S-OFF tool uses :D

So nothing new there. Thanks anyway :)

[Desire HD Android Development] wwfc:
Hi guys, great thread but i have a problem. I'm an eejit and i haven't got a clue where to start. Iv'e created my goldcard and put the .zip file to the root of my sd. Now i don't know where to go, iv'e opened CMD but the guide says go to downgrade folder, i don't know where that is, and even if i did i wouldn't know how to navigate to it :S. Plus when i try to execute the first command i get- adb is not recognised as an internal or external command, operable program or batch file. someone help please iv'e been up all night downloading things and creating goldcards, i really wan't to put a custom rom on this goddam thing, get rid of all this crappy orange bloatware. WHY OH WHY DID IT SHIP WITH 2.2.1?! Sorry for the long question, i just haven't the foggiest where to go now :(

edit: I now have downgrade folder (being the eejit that i am i completely blinkered past it on the first post :P) but still have a problem. The folder is in the root of Vista (C:), so in Command prompt i put C:\Users\Alex>cd Downgrade as your picture shows in the first post, but i then get a response saying - the system cannot find the path specified. I'm really struggling here guys, someone give me a clue! I've had a pop at HTC via email, asking why they felt the need to make it so difficult to root and s-off in anything other than stock 2.2 :S
[Desire HD Android Development] zhaominghao:
thanks for sharing
[Desire HD Android Development] adrianyujs:
But still, 2.37 can't be root yet..

Sent from my Desire HD
[Desire HD Android Development] wwfc:
Anyone?! I'm really confused :$
[Desire HD Android Development] UpInTheAir:
Patent ?
[Desire HD Android Development] jkoljo:
Nah, the hack is under GPL, freely usable.

For the guy who has problems with cmd, use command "cd .." to go down in the directory tree.
[Desire HD Android Development] wwfc:
Thanks, worked a charm. now i'm not sure what to do in the bootloader, it says checking PD98IMG.zip then has a menu with fastboot, recovery, factory reset, simlock, image crc. Which do i choose? sorry for being a pain. I don't want to get this far for nothing :P

Edit - got it, reformatted sdcard and repeated goldcard and whole process and worked great, downloading RCMix3d now
[Desire HD Android Development] jkoljo:
It should load automatically. Format your SD card with full format to FAT32, put the PD98IMG.zip again into the card and go to bootloader. You do not need to run any command line stuff again.

You can also check the md5sum of your PD98IMG.zip, you can find the correct sum in the first post.
[Desire HD Android Development] hmpfbla:
Thanks for the hint!

I searched for the software number with keywords android and downgrade and found a thread with a solution for 2.36.207.16-Users:

http://xdaforums.com/showthread.php?p=14761903#post14761903

So

1. Upgrade

2. Proceed with the instructions from this thread or use the one linked in the above.
[Desire HD Android Development] DotNetRules:
Oh man...... I was hoping there was something of value there for you all :(

I pulled the rom.zip from that RUU, placed it my GoldCard, restarted into boot loader, it found the zip (I had renamed it PD98IMG.zip), then on the screen it displayed Found "PD98IMG.zip" then "Loading....." with a verticle progress bar, which took a few minutes, then once that completed it displayed "Checking...." (or Verifying....) which again took a few minutes, once that finished the boot loader screen reappeared, the device didn't restart or anything like that, does that mean the rom was installed? or is it meant to do something afterwards? The HTC guy says once I'm able to get that rom installed the ATM tool will give me temp root as it did their end :rolleyes:

Thanks

Edit*: I've just been told by HTC that the problem is with the 2.37 OTA update, evidently if you reflash with the same 2.37 rom.zip (has to be the exact version/radio number as the OTA, renamed to PD98IMG.zip) you can then gain temp root. Evidently there is some type of difference between OTA and Full Install. I'm willing to try if someone can tell if the above mentoned processed is correct. I appologise if this is a goose chase, just sharing what I'm being told.

Edit*: HTC say you need to "Wipe Cache" under recovery then do "clear data/factory reset" before this is attempted.
[Desire HD Android Development] jkoljo:
That is bs, you cannot get temproot even if you flash a PD98IMG.
[Desire HD Android Development] DotNetRules:
I think what they are saying is flashing a full version rather than an OTA and from that point on you can root. If thats BS I'm being fed then I'm not very happy :mad:

Ok can we try something different.... What can I ask them for that will help you and everyone else to root 2.37, I will contact them and see what we get back. I'm new to this so please give the me names/terms/tools that they will understand. Its got to be worth a try. If that fails then I give up :confused:

Thanks
[Desire HD Android Development] jkoljo:
Yeah it does not make a difference whether you install full version or OTA. Well we have to get RATC, psneuter or Gingerbreak working, but I doubt a normal customer service agent knows any of those. Basically we just have to achieve even temporary root rights in command line, then I can adjust this guide to work.
[Desire HD Android Development] evanbigfan:
please do it ,we are counting on u,if i just bought dhd and the first thing i did is upgrade it OTA,if i had read this before then i was having a rooted device :( ,poor me

Having real problems here guys. I rooted my phone some time ago and I reinstalled stock rom not knowing it would unroot my phone. Now I can't get this to work.

I followed all the steps and 9/10 get an error saying im not permitted on the second to last step in section 2a.

However when it does work I follow it through to the end and then I reboot into bootloader and nothing comes up. I can't remember what I'm meant to do next? I have that file on my sd card and nothing pops up.

Same, +1.

This lack of downgrading and rooting is annoying.. Can't even get the phone to sync clock properly anymore and GPS no longer works..
[Desire HD Android Development] DotNetRules:
This is a known issue in 2.37, affects some and not others, I've come up with this solution so far: In applications press 'Clear Data' for Google Maps, Clock Widget, Weather, HTC weather sync provider and Weather Provider. You will loose Countries in in the clock and weather, but you can simply re-add them, or do a factory reset afterwards to get all the default countries back. The clock will still error (if it currently does) whenever you restart the phone, so you'll need to redo the time/location setting each time, you may also receive the error if you manually refresh/download weather, chances are your WiFi range sux as well after the 2.37 upgrade compared to Froyo. 2.37 has soooo many problems in my view. Hope this buys you some time while we wait for 2.37 downgrade.

Edit* If you have the clock widget on any of your screens then delete it first, do the proceedure above, restart the phone, re-add the clock/weather.
[Desire HD Android Development] [Aek]:
Are you referring to the clock issue or the gps issue?
[Desire HD Android Development] DotNetRules:
Both issues
[Desire HD Android Development] ajoshi9194:

This so suxx, I want to flash a ROM, bt I hv to wait as thr r no means to downgrade 2.37.

Pls request developers to make something to solve this problem.
[Desire HD Android Development] [Aek]:
My issue with the clock is more to do with unable to sync using an app called "Clock Sync", so that won't be fixed.

Anyway, I'll give it a go to fix the GPS. Thanks.

i am so friggin desperating right now

i got my DHD back after 6 (!) weeks of repair. reason enough to angry.

well. I wanted to root it like I did in the earlier days before.

Hah, good joke. stupid HTC updated it to 2.3.3 and I can friggin root it anymore.

I did everything . even created a gold card. prolly about 10 times now.

I never get to the part where the tutorial says : If you get a #, rpoceed with these commands.

I always get stupid dollar sign $ after the adb shell command and thats it... damn !!! I hate htc so much never gonn a buy it again...

can you guys maybe help me?

sorry for the anger :D
