Hello,

i have the newest Froyo from o2 UK on my HTC Desire..

My HTC Desire:

o2 Branded, Android 2.2, Software: 2.14.207.1, Baseband: 32.44.00.32U_5.09.05.30_2,HBoot: 0.93.0001

Can i downgrade my Desire with this tool without problems???
[Desire General] senninha:
my SW is 2.13.707.1

as for the error message, it goes through the verification process then says "UPDATE...FAIL!" or something like that.
[Desire General] teppic74:
It should give a reason for the error, e.g. rom version, CID, etc.

You can otherwise just flash the Asia ROM directly if you wish, the RUU is available here:

http://shipped-roms.com/shipped/Bra...00.28U_4.06.00.02_2_release_126179_signed.exe

Only use this if you have an AMOLED screen.

Hi Teppic 74

I've just tried to use this tool in win 7 x64 ultimate,

installed all drivers again for HTC, when I run the win down it's only goes till deamon started succesfully and that's it, no further that that,

Phone connected as usb charge only, phone is sim free

Any ideas? or just get a x86 to try?? (just need to swap the machines over)
[Desire General] teppic74:
Try restarting the computer first, sometimes the drivers can get messed up in Windows.

If that gets you nowhere then try with the x86 machine. That'll be the easiest way.

__________________

If this tool has helped you, maybe buy me a beer?
[Desire General] misiokicio:
I tried x86 and is exactly the same,

I have tried another sc card 1gb, still no joy...

I follow all instructions
[Desire General] teppic74:
Are you certain you've enabled USB debugging? You'll have a triangle with an exclamation mark through it in the notification bar if you do.

If you have, try restarting the phone.
[Desire General] misiokicio:
You were right!! My mistake, Just tired after long day in work!

It's pushing the files through

I'll let you know in a sec...
[Desire General] misiokicio:
All was ok, pushed files fine,

Obtained root access etc.. When booted to Hboot and when I choose the bootloader option, image wasn't veryfied or missing! cannot get that working

My CID retrieved is HTC_001

/data/local/mtd0.img: OK
[Desire General] teppic74:
You have to wait up to 20-30 seconds for it to find the file. Otherwise try formatting your sdcard (fat32) or using a different card.
[Desire General] misiokicio:
Cool, Im gonna try again with another card

It's loading the file now...
[Desire General] tonypony:
worked 100%

thank you kind sir.
[Desire General] misiokicio:
You're the Man !!!!!!!!!!!

Worked like a charm after all!! What a fantastic tool,( hopefully guys from htc will not put theirs dirty hands on it!)

I owe you a beer now!!! Give me couple minutes and I donate for your pint!!
[Desire General] garyb01:
Fantastic! Finally! Thank you very much, worked like a charm with my unbranded Desire, easily went back to 2.1 update 1 and I now finally have a rooted phone!

Thank you for the effort, much appreciated!
[Desire General] teppic74:
Glad you finally got there! And thanks for the beer :)
[Desire General] misiokicio:
You're more than welcome:)

Thanks again for all your effort!!
[Desire General] teppic74:
New version uploaded!

Main change is Mac OS X support.

I've kept the previous download links posted because the download limits are reached quite quickly. Version 2.1 will work fine for anyone on Windows/Linux.

[Desire General] naguz:
I have a few questions about this

- Why is the original readme-file for rageagainstthecage not included?

- Why do you not give the people behind it any credit?

- Why do you not give out their PayPal-indo alongside your own?

Dont get me wrong, it is great that you have adopted their exploit and made a finished working package out of it for the Desire. But unless you are part of The Android Exploid Crew, this is not your work to take either credit or donation for. At least not all by yourself.
[Desire General] Vildar:
Hey there, wonder if you can help. I ran the program fine, it all seemed to go well, apart from when it reboted into blootloader. i had a message pop up a few times then flash of saying

"PB99IAG.zip image not found"

Something along them lines anyway, it flashed of to fast.

But checking the download folder i see that the zip file is named "PB99IMG.zip"

Any problems here?

EDIT: On closer inspection it seems to go through a series of text, each image file name different to the other in some way. Then it all flashes off before i can properly read it. And just hangs there in the boot loader untill i reboot. Not sure if i did anything wrong.
[Desire General] teppic74:
@naguz: I developed all the scripts and the downgrade method myself, which took several days of work. The binary I use to gain temporary root access isn't hidden in anyway, I've not even renamed the file, and that exploit alone won't do anything to downgrade the ROM.
[Desire General] teppic74:
Can you try another sdcard?
[Desire General] Vildar:
Will try now, just got to do the HxD edit thing to make it a goldcard.

That wouldnt be a problem would it ?
[Desire General] teppic74:
It seems that the phone's firmware can't find the file on some sdcards. It should at least find the file whether the card is a goldcard or not.
[Desire General] Barosz:
i have a 2.09.405.8 unbranded desire (2.2). after i downgrade to 2.1 can i use update from phone to update again to 2.2 if i want to ? (i have a gps fix problem and i hope to solve it this way) thx in advanced
[Desire General] Vildar:
New SD didnt do a thing. Still same output staiting it cant find the image.

Both SD's i have tried are 2GB cards. Both formated to FAT 32 i belive.
[Desire General] teppic74:
You can, but it's unlikely to fix it if you simply upgrade back to stock froyo...
[Desire General] teppic74:
They have to be formatted to FAT32 I think.

You can also try running the downgrade RUU in Windows, there's a link in the first post.
[Desire General] Barosz:
then what do you recomend me to do ? i dont no for sure why my gps does not work. on stock 2.1 worked after update no gps fix....
[Desire General] Vildar:
Sorry, i should have said before. Im running windows 7 32 bit.

When the program finishes, i can see the files

"mtd0bak"

and

"PB99IMG" when i mount the SD card as a removable, or check it using a SD adapter.

Aswell as 3 folders from the android format.
[Desire General] teppic74:
As long as file passed verification it's something to do with the phone accessing the sdcard. I'm not sure what causes it, for others using a different sdcard has worked.

If you run this executable in Windows it will do the equivalent as loading that file from the sdcard:

http://shipped-roms.com/shipped/Bra...1.00.32U_4.08.00.09_release_137222_signed.exe
[Desire General] Vildar:
Hey again.

Im not sure what fixed it, but i just went over everything again.

Reformated to FAT32, recreated the gold card. Etc.

And it seems to have worked.

Thanks a million for this tool. Now, how do i buy you a beer ? :P
[Desire General] teppic74:
Heh, the pint is purely voluntary :)

I think formatting the card usually sorts it out.
[Desire General] olec_:
¿Anybody has done for HBOOT 0.93? it's confirmed that this downgrade method works fine for 0.93?

Thanks all
[Desire General] GFerry:
worked like charm, thx for the soft mate :)
[Desire General] zagevent:
yes it works
[Desire General] olec_:
Sorry for my ignorance, but i have updated by OTA from 2.1 to froyo 2.2 wich cames with HBOOT 0.93 and 2.10.161.2 ROM and 32.44.00.32 radio (VODAFONE)

My desire has AMOLED display.

Can i apply this method to my phone?

thank you very much!
[Desire General] EddyOS:
As the title says, ANY HBOOT, so it should work fine...
[Desire General] Barosz:
worked for me 2 !
[Desire General] teppic74:
Yup. It uses a flash procedure to downgrade that is present in every version of hboot, so the version of the bootloader isn't relevant (at least for all existing ones).
[Desire General] garyb01:
Same spec and it worked perfectly for me.
[Desire General] WillyTP:
Hello everybody...

Excuse me for my n00b question,

I have an European (Italian) HTC Desire, is it CDMA or not?

I wouldn't brick my mobile :-)

Thanks
[Desire General] Dave_S:
ALL of Europe uses GSM/UMTS so your Desire is definitely not CDMA. CDMA is primarily, but not exclusively, used in the USA.
[Desire General] babynips:
Worked Great on my HTC Desire with stock 2.2 Thanks soo much
[Desire General] sam9s:
teppic, I am in the same boat, PLZZZ help me, my screen also went blank when I tried to downgrade :(, but the rom you have suggested gives me the following error ....

ERROR[131]:Customer ID Error

The ROM update utility can not update your android phone

Please get correct update utility and try again

I would have posted the image but I am not yet authorized to do so (being a new member)

I have HTC Desire with S-LCD bought in India (Asia)

Please help me as I have completely lost my phone .....
[Desire General] BrainMcFly:
try with goldcard, although its unbrandet.
[Desire General] sam9s:
Can you point me to the right direction, to create and use gold card ....

Remember I cannot see anything on my phone ....
[Desire General] xfile087:
Hey guys, just downgraded mine on a Mac. I don't know if it's been mentioned (I do apologise if it has) but the downgrade would not work until I commented out or deleted "exit" on line 23 of downgrade.sh. I don't know if it's a mistake.

On a side note it went perfectly after that and I'm now downgraded!
[Desire General] teppic74:
Gah - that may be a mistake from testing. I'll have a look at it and upload a new version if necessary. Cheers.

edit: yup - I forgot to remove that from testing. I'll correct it with an update as soon as possible.
[Desire General] sam9s:
teppic74, I was waiting for your reply ...... can you please help me here, I am just sitting with a Blank screen with my phone, and its a brand new phone ..... Plz help me to get it back .....
[Desire General] xfile087:
I don't think you can make a Gold card with a phone in which you can't see the screen? I'm pretty sure you need to upgrade to stock Froyo and then downgrade again using the tools provided?
[Desire General] sam9s:
The stock froyo link provided in this thread does not work, gives the same CID error, I tried couple of other from Shipped-Roms.com but non works all give the same error ...... man I am dead ,,,, I hope the phone hasn't become unrecoverable ......... HELP!!!!!:(
[Desire General] teppic74:
sam9s - this isn't the right thread for your problem. As has been said, you need a goldcard to apply the froyo update, otherwise you will get CID errors.
[Desire General] sam9s:
Which thread then ... open a new one?? ok i will ............... Just tell me how am I suppose to create a Gold Card without not being able to see anything on the screen .......
[Desire General] sam9s:
Ok created a new thread ........

http://xdaforums.com/showthread.php?p=7992503#post7992503

No is willing to help this poor chap ... :-(

BTW I get Failed to get CID while creating the gold card ...... USB debugging might be the issue but can check and can enabld it as well as the screen is blank ....
[Desire General] ultrafast_sunglasses:
Thanx a lot!

Hi volks!

I successfully downgraded an amoled vf hboot0.93 desire.

The only small issue was:

Usb debugging mode wasn't switched on in my phone.

The win-down.bat wouldn't tell me about this problem/requirement, but instead just stopped at one of the first steps and refused to do any further stuff.

So I hat to do a little bit of investigating... (a good thing, so I had no chance of being bored this night... ;-)

After switching-on usb debugging mode, telling myself what a jerk i've been and finally rerunning the win-down.bat, everything worked just excellent! :-)

Thanx a lot for this great tool!!

Greetz,

Al

(total newbie)
[Desire General] teppic74:
The current version (2.2) reminds you to enable usb debugging when you run it. It does clearly tell you to do that in the instructions in the first post, by the way :)
[Desire General] 74mosquitoz:
This work flawlessly for a completely noobs like me :D ..thanks for the great effort..very much :)
[Desire General] teppic74:
Just a reminder that in version 2.2 the Linux/Mac version doesn't work. I'm uploading a fixed version at the moment.

edit: now available.

[Desire General] [steve]:
Hey Teppic,

This tool looks great on my iMac and the terminal part runs a dream.

I am (and have been getting for the last 24 hours) the error that says

Loading...[PB99IMG.zip]

No Image!

Loading...[PB99IMG.nbh]

No Image or Wrong Image!

When loading the Bootloader.

Mine's an unbranded Desire. Just got it back from HTC after a main board replacement... they loaded the newest Froyo on, hence needing to downgrade!!

I have tried 3 SD cards, 1 x 512mb and 2 x 2Gb ones and always getting the same message about no/wrong image!

I noticed the Mac formatted the 512mb one in FAT16 but the 2Gb card was formatted as FAT32 but still doesn't want to work...

Must have formatted the card and run the utility 10-15 times now.....

Can you shed any light on what i'm doing wrong??

Thanks.

Steve.
[Desire General] teppic74:
I think if you format the sdcard on a Mac it can lead to problems. Try formatting the cards from the phone's settings.
[Desire General] [steve]:
Will do, i'll let you know what happens..... Thanks for the quick response :)
[Desire General] timmy1980:
Sorry its taken me a while to post this but THANK YOU.

I had tried every method I could find to root/downgrade my desire but always failed at the flashing of clockwork recovery. My phone would not boot into a custom recovery only the stock one after I had flashed the official froyo update.

I was actually at the point of arranging an exchange of my phone due to a "fault" when you came up with this and it worked FLAWLESSLY.

I now have my phone downgraded and rooted... mainly for a2sd+.

Thanks again.
[Desire General] [steve]:
Nope.... formatted the 2gb card in the phone and it's still saying no image or wrong image... :(

I'm making sure the phone is connected 'Charge Only' and that it's set to ask... is there any way I can test that the phone is recognising the sd card at bootloader??

Is it possible for me to rename PB99IMG.zip to Update.zip then head into recovery and run the update.zip command from there... or could that fook up my handset?

This is the outcome of the utility... (the latest run)....

[Desire General] teppic74:
The tool is doing everything it should - so it's an issue with your sdcard. Maybe try formatting it in Windows. If you formatted it in a Mac, try formatting it again but make sure it's set to DOS MBR style and *NOT* GPT.

Alternatively, if you have Windows, you can flash an RUU directly now.
[Desire General] [steve]:
Cheers mate. I don't have a windows machine... may have to borrow my dad's laptop... same as I had to when I flashed back to stock before sending to HTC for warranty repair....

Thanks again for the support..... really appreciated :D
[Desire General] teppic74:
I think that if you format the larger card in OS X but ensure the partition type is set correctly it'll have a chance of working.
[Desire General] [steve]:
In Disk Utility it only has one option - MS-DOS(FAT)

OSX seems to decide on what file system it's gonna format the sd card as.....

Are there any advanced options I can go to, or another program for OSX that will format the card properly???

Cheers.

[Desire General] teppic74:
What did you do in the end to get it to see the file on the card?
[Desire General] osnola ivax:
can i just run a stock RUU 2.1 file to downgrade from official OTA froyo 2.2

Hi folks,

I had my phone rooted and was running open desire. But I found I couldn't use the phone when it was charging or it went into a reboot cycle. Anyway, I took the notion to unroot. Mine is a branded o2 Ireland desire so I thought I'd use the opportunity to demand it aswell.

So I created the gold card and ran a stock 2.1 RUU. When this was done, I got a message to upgrade to 2.2 official OTA. So I did. However, the charging problem still persists so I am gonna have to put up with it so I want to re root and go back to open desire which I loved. Can I just run the stock 2.1 RUU to downgrade or do I have to follow the procedure here. Do RUU only work on rooted phones? Any advice would be very helpful.
[Desire General] teppic74:
You can't run the stock 2.1 RUU if you've upgraded to froyo without using this tool. RUUs work on any phone - rooted, unrooted, custom, stock.
[Desire General] osnola ivax:
Thanks very much, I appreciate that.

I tried it today, seemed to go through the process ok and launched the bootloader on my phone. I pressed power to enter bootloader but then nothing happened. I got no option to downgrade, ie volume up to start or down to cancel, I don't think it picked up the zip file.

I did however run a ruu stock 2.1 and this worked a treat. Rooted again now on od 4.0.4. Thanks mate.
