[Desire General] AdamZA:
Thanks for releasing such a powerful tool! Trying it as we speak but having a problem...

I've entered my CID on http://ks33673.kimsufi.com/misc/index.php but it says its not valid and to enter one like HTC_01...

I've created a goldcard with this CID so I don't think its wrong. Any ideas please?
[Desire General] teppic74:
A goldcard cid and phone cid are not the same thing. The phone cid will always be 8 characters long.

I will update the thread with details on how to find the correct cid later (the Linux version finds it for you).

You can try skipping this part and using the supplied mtd0 image. It may also work if you enter 11111111 instead of your own cid, but this needs testing too.
[Desire General] AdamZA:
Thank you for the quick reply! I will try the options and report back.

If it fails because of this incorrect file, will it result in a bricked phone or anything like that?
[Desire General] teppic74:
I think that it should be safe but I can't guarantee that.

If you have access to the android sdk you can find your CID this way:

Boot the phone in fastboot mode (back key and power button)

Run on the PC with the phone connected: fastboot oem boot

This will list the phone's cid in the output. It's difficult to obtain this information on a phone that isn't rooted. I will include the fastboot binary in the next version of the utility.
[Desire General] AdamZA:
Okay, I am just downloading the downgrade file. I will try it without changing the mtd0.img file so we can see if the step is needed.

Fingers crossed!
[Desire General] teppic74:
I have a feeling that with a goldcard in the phone the CID you enter is ignored and that the partition will be updated with the correct version when you downgrade anyway. I'm not certain though.

The supplied mtd0.img file has a CID of O2___001.

edit: I tried flashing a CID of 11111111 and it didn't seem to do any harm.
[Desire General] Subliminal10:
You and lollylost100 are great guys. Once this Phone CID issue is resolved I will definitely be following this tut. Thanks for all your help
[Desire General] Theqie:
Hi, and thanks you very much for the utility. But I'm getting stuck at the error below, any tip?

(Win7 x64, HBOOT 0.92, SLCD, No branded phone - No Goldcard.)

adb server is out of date. killing...

* daemon started successfully *

failed to copy '/dev/mtd/mtd0' to 'mtd0bak.img': Permission denied

Flashing misc partition.

Done.

If you saw any error here, press ctrl-c and try this utility again.

Press any key to continue . . .
[Desire General] teppic74:
It looks like the backup cannot be written to your computer for some reason, although the flash appears successful. As long as there are no other errors you can proceed there. I'll look into that error in a little while.
[Desire General] BrainMcFly:
because unrevoked hast be be run with admin-privileques on x64-systems, it has to for this tool too. Maybe try to start it "as Aministrator"
[Desire General] Theqie:
I proceeded and the phone is now being downgraded without errors (so far), thx.
[Desire General] Chura:
Not for me, but Thank for the effort !
[Desire General] AdamZA:
Done - now running Eclair 2.1.

I had my goldcard in the phone - DID NOT change the mtd0.img file.

Encountered error in the installation:

failed to copy '/dev/mtd/mtd0' to 'mtd0bak.img': Permission denied

Continued anyway.

Will now use unrevoked and then install a different ROM. Thank you for all the hard work.
[Desire General] fieryriver:
well this is great for slcd users. I had to suffer through a black screen before i managed to downgrade and root. I should have waited it would have been a lot easier but it was worth it...can't believe i ever thought i wouldn't need to root. custom roms are awesome
[Desire General] teppic74:
There's clearly a problem with the mtd0 backup - I'll fix it or remove it in the next version. It's safe to ignore that error so long as the flash works without an error.
[Desire General] igor7:
This method working great!! I downgraded my Official HTC Android 2.2 (FroYo) ROM without any problem (I used Linux). Thank you very mach!!!
[Desire General] balthor80:
It's realy works on SLCD + 0.92 hboot + OTA 2.2 ?? without black brick screen ??

thx a lot !
[Desire General] betalif:
with starting ruu I always get a Error 170 - no USB connection.

I installed the package on a new PC with win XP - no chance.

Now i try to copy the PB99IMG.zip to the Goldcard and run again, but no plan if it would work this time...

How can I find out my installed radio and rom etc?
[Desire General] Droidzone:
Copying PB99IMG.zip and trying before the downgrade util has succeeded will result in a "Software version is newer" error.

Your USB drivers on Windows seem to be at the root of it. Try the method I posted.
[Desire General] Droidzone:
It is not the PB99IMG.zip in the utlity that is special. It is the script used by the utility itself. So you need to get the scripts to run, for that a usb connection is needed.

You can find out the installed version in Fastboot mode. Switch off, then switch on by Back key+Power key
[Desire General] betalif:

[Desire General] gusribeiro:
Hi guys, could you please answer this question?

I want to update my HTC Desire 2.1 to froyo asap. This utility is usefull for me?
[Desire General] Droidzone:
What are you guys talking about?!

You're confused!

This is a downgrade utlity->Lowers the version number.

Actually this isnt needed for most purposes. Not for rooting, unrooting.

In fact, if you dont know what this is about, dont run this at all.

For a Froyo "upgrade", what you want is an OTA/a 2.2+ RUU

[Desire General] buzmay:
I might not be sure but you have a PVT4 Desire which might be the reason why you can't.
[Desire General] AGPPC:
So PVT4 means what??

Any solution ?

Thanks
[Desire General] buzmay:
Well it means they are the newest Desire and many people have had problems with them trying roofing and getting misc errors. Why do you want to downgrade?
[Desire General] Droidzone:
Hmm..I dont think having PVT4 is a contraindication for the downgrade, rooting or S-OFF.

I use a similiar Desire and I never had a problem with doing these..

The Fail-PU has been described as a misc error due to hardware fault. Not sure whether that's true..

As buzmay asked, I too would like to know why you're running the downgrade tool. It's unnecessary for most purposes-Rooting, S-OFF, unrooting etc.
[Desire General] AGPPC:
Thanks for your reply lads.

I tried to root my Desire using unrevoked3 but it fails to find my phone when connected via usb cable. May be i am wrong but what i understand is that to have desire flashed with custom rom i need to setup partition on SD card.

Also i have noticed that i cannot flash my phone with any ROM except one with radio version 5.0.11.27.

Please advise if there is any workaround. All i want is to install Desire HD custom Rom with su access on my Desire.

Thanks for your reply.

[Desire General] AIRagon:
Works even with novice

Hi Teppic74,

You are incredible, Because :

I'm a brand new HTC users (Desire) with no android knowledge. I udpated my system (OTA) 3 days ago and had my device completely blocked (because of Hboot 0.93).

After a long time spent on forums with no solution, I finally found your thread. I followed the steps, created a goldcard and after 3 tries (driver problem...) It finally works and the device came back to life,

Thank you so much Teppic, your tool is so awesome that it works even for newby with no knowledge like me,

I just noticed 1 point that could purhapse help others : As my device was completely locked (only main screen HTC and only acces to USB selection mode when connecting to PC) The procedure didn't work with the option "Charge only" as I could not set up "USB debug".

The solution was to uninstall HTC sync 3 (keeping HTC drivers) and choosing "HTC Sync" methode for usb.

Thanks again for your great Job
[Desire General] The Tjalian:
Hi there.

First of all, many thanks for this tutorial. Makes it much easier for newbies like me to get their phones customised just the way they want.

Secondly, I'm in the process of doing the downgrade. I've downloaded the zip file and made a goldcard. I've run win-down BAT file and currently it's stuck on daemon started successfully line and that's it - and it's been that way for about 5-10 minutes now. Is this normal? I just don't want to wait for 20 minutes or so and realise it's only supposed to take 10 minutes tops!

I'm currently on an HTC Desire, O2 Branded OTA 2.2 Update. Here's my stats from the recovery menu:

hey guys!

i also downgraded to 2.1 since i had wifi problems after updating 2.29.405.5 and this is the only thing that helped!

however, if i find necessary, how would i update back to newest software again?

i already tried by just accepting the automatic update and after the install, phone keeps freezing during the boot... unlocking sim card and setting up phone screen just freezes.

any ideas?

Hi, i first rooted my htc wildfire with unrevoked then i got the 2.2 Update but i couldnt install while being rooted it so i flashed it with different ROM's until i found one that supported my bootloader so now i have bootloader 1.01, but the ROM i have on now doesnt work well at all can anyone help downgrade?
[Desire General] Droidzone:
Did you notice that this is the Desire Android Section?
[Desire General] dhar9417:
i know haha, but would you know what i could do?
[Desire General] Droidzone:
We Desire users wouldnt know anything about Wildfire Hboot versions, Roms, or RUUs. Better post in the Wildfire section.

will this work on htc wildfire too ??

This program flashes HTC desire ruu on the phone. Do you really want to try it on the wildfire? Initial steps may be common. Better ask in wildfire forum

Could this procedure be modified so that it would work on HTC Legend? We would really need something to downgrade legends hboot, since S-OFF from alpharev is out, but only supports 0.43 hboot version. Some help would be appreciated:)
[Desire General] Droidzone:
If one of you with a Wildfire or Legend send a spare phone over for testing, we'd be sure to try it out :D

Honestly, guys, most of us in the Desire section have only a Desire, and have no idea..You should ask people who have had both phones. Check if rageagainstthecage exploit (the base of unrevoked) works on your phone. If it does, Just replace the PB99IMG.zip included with the script to the PB*whatever (corresponding to your phone) and try it.

Be warned..The consequences could be disastrous.

Houston, we have a problem!

hi there, im a total noob. my htc desire is running crazy lately keeps rebooting randomly after the new update from HTC.

My current specs:

First of all Ive just finished the downgrade process with the utitlity works great! Thanks teppic.

But i tried to install a HK CSL radio for waranty purposes, but it won't seem to install. ive followed the steps by pressing vol down at the end to skip the "downgrade" and tried to run the official RUU update, it all goes fine until the RUU install sheild reboots the desire into bootloader, and then Windows says, "does not recognize component" and the whole installation just stops. What can i do? Im really lost here....please please please help.

I want to go back to the release before the newest update available for HK which screwed up my phone. (prev post)

[Desire General] vkass:
yeah just get a stock rom from shipped-roms.com/shipped/Bravo/

thanks. that saved my device. but still I can't flash any older version than the latest froyo. Tried to flash an Eclair RUU and I got the same error.

Any ideas what's causing this?
[Desire General] vkass:
probably the hboot, u need to downgrade it to root the device.

without root u can only flash stock roms
[Desire General] regunus:
That's the problem. I get this error when I follow thw directions in the first post to downgrade. Then the devices hangs and boots onlu in stock recovery (where I can't even use fakeflash).

In order to use the device again I had to flash the froyo stock ruu. :-(
