Yes it works without a goldcard if you have an unbranded and unlocked phone, just done it myself.

Big thanks to all involved, I got caught up in the excitement on Sunday and kinda forgot how much I despised Sense and loved having the freedome to choose a ROM that suits.

Cheers!
[Desire Android Development] :
I have a question. How come I can't install and stock ROM after the downgrade?
[Desire Android Development] SavageCore:
just did this on 0.83 and got a black screen after pressing VOL UP.

Now the device turns on and I hear boot up noise but nothing on screen.
[Desire Android Development] Sammy83:
Thats because of the broken /misc partition.

You can fix this by using this: USB brick/rickrolled/b0rked -> FIXED!
[Desire Android Development] marinierb:
I got my new Desire from Telus today (the one with the Super LCD screen). It just came out today. It's running the following:

Telus HTC Desire:

HBOOT: 0.83.0001

Software number: 1.29.661.1.

So far it doesn't seem that the procedure works with HBOOT 0.83. Some folks here seem to have b0rked their phones! I will be keeping an eye on this thread for a solution! Good luck, guys!
[Desire Android Development] Sammy83:
I'll add a video tomorrow in addition to my guide.

I hope that will help people to get the steps right.

I'll show:

- Downgrade from 0.92 to 0.80

- repair misc partition

- apply custom recovery and root by unrevoked

- flash custom rom r7 by modaco
[Desire Android Development] black_impact:
it's me again...

can we see some useful informations?
[Desire Android Development] BongoUser:
It looks like some new Devices has a problem.

You can downgrade to 0.80, but you can't root the Desire and you can't flash

other HTC ROM's or other ROM's with Branding.

I need help with this problem too:

this all process is so ****ing difficult and risk for phone.i wish we can soon get

some batter and easy solution.i have downgrade my rom but not hboot vartion

waiting for easy way:o:(
[Desire Android Development] Sammy83:
It's not so difficult and there is only a higher risk for HBOOT 0.83 phones!

If you are on 0.92 and do the downgrade you should be fine.

Of course there is no 100% garuantee that it will work, but most of the people here succeeded :)
[Desire Android Development] heavymetalmage:
Has anyone with HBOOT 0.83 succeeded with this method?
[Desire Android Development] Owendavies:
I've got HBOOT 0.83 to on O2 UK and would like to go to Froyo but it sounds like it doesn't work yet :( Hope it gets cracked soon.

After successful downgrade from OTA HBoot 0.92 to 0.8, now my

desire is USB bricked. in Windows's device manager, when the

phone is on the normal screen and recovery mode, I see it as 3 Qualcomm CDMA Technologies MSM" items.

I'am trying to downgrade again using PB99IMG.zip, still same USB bricked. My USB, Radio FM and Bluetooth not working.

I'am trying to flash with RUU 1.21.405.2, always failed. Because when get ver in fastboot, my system version is 2.09.405.8, actualy is 1.21.405.2 (in about).

Now i can't using adb command & using USB brick/rickrolled/b0rked -> FIXED! because need root access.

Using unrevoke to rerooting, How i can rooting when USB bricked and Unrooted? with emulator terminal (need root access too).

Now i can't to update again with OTA_Bravo_Froyo_HTC_WWE_2.09.405.8-1.21.405.2_release4dua3bcrut4wrv30_2.zip

i have a unbranded Belgian HTC Desire with Froyo 2.2, DO I HAVE TO MAKE A GOLDCARD or can i skip that step?

thanks
[Desire Android Development] black_impact:
I have now returned my device because of this 0.83-problem

edit:

is it possible, the cause of this brick is, that i had i slcd?

my fw was:

RUU_Bravo_O2_DE_1.20.207.3_T2_Radio_32.41.00.32U_4.08.00.09

and the last amoled OTA was:

RUU_Bravo_O2_DE_1.20.207.3_Radio_32.36.00.28U_4.06 .00.02
[Desire Android Development] BastiaanN:
Because Samsung (the manufacturer of the amoled displays for the Desire) cannot deliver enough amoled screens they started replacing them with super-lcd displays in newer Desires. Could it be that Desires featuring a super-lcd display use HBOOT 0.83 and that HBOOT 0.80 is missing support for super-lcd displays?
[Desire Android Development] teppic74:
It's possible that you need 4.08.00.09 or better to use with an SLCD Desire. There's an RUU available with this radio, so flashing that may debrick the phone.
[Desire Android Development] Sammy83:
First video online for downgrading progress: http://www.youtube.com/watch?v=VdWt65tUBVc

Second part is coming in a short while (misc partition and custom rom)
[Desire Android Development] Komadyret:
Sorry if this is a somewhat stupid question, or if it is answered earlier, but I'm trying to rid ALL uncertainties out of the way before I proceed with my rooting. I'm a first-timer :o

After I've done the downgrade by instructions given in this thread, I've considered installing the ROM from the thread named:

[ROM] Rooted Official HTC Android 2.2 (FroYo) ROM [Market issue fixed]

In the thread about that ROM install instructions states that one should install latest radio before installing the modified ROM. Isn't my OTA'd HBOOT 0.92 already fitted with the latest radio, or will this downgrade process leave me with the older radio too?

I'm still somewhat confused about the differences between a radio, a ROM and a RUU and what they're used for :o
[Desire Android Development] Sammy83:
After the downgrade you are on HBOOT 0.80 with an old radio.

Use the ROM from this thread: http://android.modaco.com/content/h...-froyo-pre-rooted-no-hboot-with-radio-deodex/

it has the actual Radio included.
[Desire Android Development] teppic74:
If you try to use FroYo with an old radio you'll get no signal and your phone will constantly reboot. Official updates always contain a radio too, but custom ROMs let you choose which radio to use (which requires rooting).
[Desire Android Development] Ch3wyzzz:
Can someone help me i have erverthing done as the guide told and have flashed opendisire 3.5 and rebooted and niw it says that there is no sim card in it but i have it insert can someone help me thx
[Desire Android Development] Komadyret:
So if I downgrade and apply the ROM linked to in the first reply, I will have the latest radio, and a "stock" rooted HTC-Sense-Froyo ROM, and can easily re-flash any modified ROM later if I wish so without bothering about installing any new radio until the day comes that there is a new update available?

I'm still looking at a ROM that has that slight Market issue fixed, but can re-flash to that later, if the ROM from the modaco forum gives me an easier way of installing the radio than the separate install :)
[Desire Android Development] teppic74:
No. This downgrade gives you unbranded and unrooted Android 2.1 and a radio that works fine with that, but not with FroYo. But you can root that and then update the radio and apply a rooted custom FroYo ROM if you want to. If you apply the OTA update to FroYo you'll be back to where you started (latest software and radio, but unrootable).
[Desire Android Development] Komadyret:
Oh, sorry. I've jumped the wagon a bit here. I was reading the howto/tutorial linked to in the first post of this thread. It has rooting using unrevoke listed as step 2 after downgrading and then goes on with flashing a misc-repair and a costom ROM :)

It certainly won't take me back to unrooted Froyo
[Desire Android Development] black_impact:
can you tell me where you saw this RUU?
[Desire Android Development] txitxi2004:
misc partition and custom rom

youtube.com/watch?v=T88G3px7Ztc

from sammys channel

:D
[Desire Android Development] teppic74:
hxxp://shipped-roms.com/shipped/Bravo/

It also contains hboot 0.83 - either this or the new radio seems to get the phone working again. It could be that hboot 0.83 is necessary to initalise the display on SLCD desires, but this is conjecture.
[Desire Android Development] txitxi2004:

[Desire Android Development] txitxi2004:
Please could you recommend me a 2.2 ROM which does not create radio problems. I am the biggest noob here. Does app2sd thing work by default?
[Desire Android Development] Sammy83:
Radio Problems CAN occure by some Providers. So i can't say which one suites your phone.

2.2 has App2SD is build into froyo but the froyo one sucks ;) because there very few apps which you can copy to SD.

If you want real App2SD you need root.

I used this ROM in my videos which provides the latest Radio:

http://loadbalancing.modaco.com/dow...avo-stock-rooted-busybox-withradio-signed.zip

If you want to use the root App2SD you need en EXT3 partition on your SD card.

I couldn't root so i add this HBOOT, and now i can't install froyo (official)

So i tried use original RUU but it can't flash original room, say error 140.

What can i do ?

where can i find HBOOT 0.75 ?

and if i try to root my phone it's says error 43
[Desire Android Development] Sammy83:
you must use the misc_partion after using unrevoked method to get root recovery.

After that you will be able to install what ever you want.
[Desire Android Development] black_impact:
a question again because the problem that I had.

can it work if I try the Arab RUU to flash and then again the o2-flash version, so everything is back to normal?

the arab version and the o2 version have hboot 0.83 and the newest radio with slcd-support...

i cant simply try it because i won't brick my phone more... i'm going to send it back.

if the chance is low, i let it be
[Desire Android Development] Komadyret:
Will the custom recovery provide a partitioning tool for the ext3, or should I go about getting the card partitioned on my computer before starting the downgrade/flashing procedure?

Crap, just as I'm writing this it becomes all obvious to me! If I partition the SD card all data/files will be lost, and I will have no ROM on the card to flash after partitioning :p

Decided to leave the post here anyway, I can't be the only noob here trying to do too much in one go! :rolleyes:

Think I'm almost ready to pull the plug here. Heart rate is picking up slightly:eek:
[Desire Android Development] Sammy83:
No problem :)

If you want an EXT3 partition the easiest was is if you have a linux system running (VM,emulated, live-cd - just google ;) )

The other way is to download a windows (or mac) tool to do the job. (google again)

And yes all you data will be lost on the SD card so i advise you to make a backup before!

And remember: You only need an ext3 if you pkan to use the rooted version of app2sd not the froyo one!
[Desire Android Development] Sammy83:
Again, i have no experience with HBOOT 0.83 or any other firmware versions. so i must apologize for that :)

I just can proof that it works with HBOOT 0.92 official stock froyo rom and the files mentioned in my guide.
[Desire Android Development] Komadyret:
One quick question that came to mind; at what point do you plug the USB cable? Do you keep it connected to the computer during the whole procedure? The howto didn't state it, but it seems rather obvious when it should go in....
[Desire Android Development] Sammy83:
yes i leave it connected all the time (i think :D )

You must plug it in when you want to remove the PB99IMG from your SD.

At least you have to plug it in at step 2 when you do the unrevoke thing.
[Desire Android Development] :
Once you have transferred the PB99IMG.zip in your phone's SD card you just have reboot the phone in bootloader mode by holding VOLUME DOWN button while you press the power button. Like Sammy 83 mentioned you only need to connect the cable to delete\rename the PB99IMG.zip after the downgrade.

And you just let it go until it's finished.

Once it's done you just re-root the phone with unrevoked.
[Desire Android Development] Komadyret:
I'm a bit stuck here, can't seem to get the android usb drivers to install. Any advice? Also when I enable USB debugging all installs well exccept for ADB. I guess this is the stuff the driver is suposed to handle?

[Desire Android Development] x-layer:
Hi.

Yes, i've try this method on my Desire and it works. But my phone is "old" with AMOLED screen. I've sent it for repair and HTC replaced mobo and flashed HBOOT 0.83.

But for SLCD Desire i dont know.

Regards, X.
[Desire Android Development] heavymetalmage:
Yeah, it seems that 0.83 and higher is required for SLCD screens.
[Desire Android Development] Komadyret:
Dun & Dun!

Alright...

Downgrade and rooting went reasonably smooth. A slight mishapping at drivers install, but that was my own fault :o

Now I've flashed LeeDroid. Gonna give that one a try, looks promising.

Thanks for an excellent guide :cool:
[Desire Android Development] Sammy83:
You're welcome :)
[Desire Android Development] heavymetalmage:
@Sammy83

I would put a warning in the first post that if the user's desire is on HBOOT 0.83, then they shouldn't try to do the downgrade (unless they know that they have an AMOLED screen.)
[Desire Android Development] Sammy83:
Thanks, i have put a warning on my tutorial page already. I think that should be enough.
[Desire Android Development] BongoUser:
We have found a solution!!

DO NOT DEINSTALL HTC Sync for unrevoke process!!

If Windows ask you for the driver, select modified driver directory.

This do NOT work with Win 7 for me.

I had to install Win XP for this.

How can i downgrade 0.80 to 0.75? Currently root with custom ROM.
[Desire Android Development] Sammy83:
Why do you want to downgrade to 0.75?

My guide is ONLY!!! for downgrading from

0.92

to

0.80

Don't use it if you have 0.83 or an SLCD Device!
[Desire Android Development] jamaljmys:
sammy

any help in this issue please...............
[Desire Android Development] Sammy83:
If you choose the full wipe factory reset then all data including ext3 partition will be lost. the partion itself will remain untouched.

If you apply the misc partition fix then you can use any root method you want.

But you have to use unrevoke in first place.
[Desire Android Development] jackytang520:

Maybe you could add to step 2 that you need to install HTC Sync furst and need to uninstall it, but leave the drivers installed...

Hi,

Regarding downgrading hboot 0.92.

i am on stage 2. Step 3 says

3. Download the unrevoke recovery USB driver here and install them!

how do i install them? I unzipped them and got 2 folders and 3 files. I tried to right click on android_winusb.inf and click install. Then i get an error message saying the inf file you selected does not support this type of installation.

I did uninstall the htc drivers and sync.

If i plug in my phone to htc sync i can see anything on my device manager. if mount usb its fine. how can i install this driver?

Please help i am stuck.

btw downgrading hboot went very well. on 0.80 now with 2.1 update 1:)
[Desire Android Development] txitxi2004:
Nevermind i figured it out:D

For others who might get stuck on this step.

I did Right click my computer ->manage->device manger.

Then at the top menu Action-> Add legacy hardware.

Then choose install hardware manually and choose the inf file from the unzipped usb driver files.

BTW i successfully rooted

Thank you Sammy

Could not do without your awesome tutorial :)

what do you guys do after rooting?

apps2sd?

:D
[Desire Android Development] chill today:
I know now that what I see is normal when booting to recovery.

What I am concerned about is.

I have now unrooted and back on stock ROM. 2.2 Froyo. I was having reliability issues with some cooked roms.

OK, so out of curiosity I booted to recovery (vol-,power) and I still see the PB99IMG.zip flash up for checking on sd card.

Surley this is a mark left from doing the downgrade.

If HTC take my phone for repair and fire up recovery, they will see this and know that something has been tampered with, SO NO WARRANTY.

Any thoughts on this.

chill.....
[Desire Android Development] Orphee:
Hello :)

Just a quick question...

In order to downgrade and root, do we must wipe the phone ? or not ?

PB99IMG check in recovery ??

I have the same question, the thing is i am very happy with my open desire rom but what if i want to downgrade or have some warranty issues do i still have

PB99IMG flashing in recovery ?
[Desire Android Development] armadax:
I have tried the method described on your page. The image is identified, but the CID error remains. I was wondering whether I made a mistake with creating a goldcard, but I've done the process half a dozen times now and the first time I did it, I was able to unbrand to the stock HTC froyo rom.

So, I'm stumped: just create a goldcard and put the image on it right? I made sure not to use the zip.zip (that would trigger a problem with recognition of the file), but I keep getting a problem with my CID. I've tried a FAT/FAT 32 format, making new ones, creating it on the PC with a card reader versus through a USB cable.

Does anybody have any good ideas on this?
[Desire Android Development] billyjoego:
Hi, thanks for the info and support.

Is there any way to tell if a phone is AMOLED or SLCD when it is already at HBOOT 0.92?

I didn't see if it was 0.83 before OTA upgrade, and searching both google and here hasn't found me the answer.

Thanks
[Desire Android Development] brindyman:
Check the box your Desire came with at the section Display: if it states "3.7 inch AMOLED touch-sensitive screen" then you've got an AMOLED display but if it says "3.7-inch touch-sensitive screen" then you've got an SLCD display.
[Desire Android Development] vnvman:
Same here. Any suggestions?
