Can't get beyond Hboot after downgrade
OK, I'm not a noob but neither am I an expert and I have now got myself into a terrible pickle.
After running this tool, I have now unrooted and S-Ond my device so that HBOOT shows:
Bravo PVT1 SHIP S-ON
HBOOT-0.930001
However, I cannot load RECOVERY from HBOOT and neither can I boot into the ROM. I ahve tried both flash methods to put on a stock rom with the same radio as reported by my HBOOT,
RUU works successfully in flashing.
PB99IMG unpacks with all OK and completes the update.
But on reboot, I get stuck at the splash screen (white screen with green HTC logo) which then bootloops about every 90 seconds. I cannot select Recovery. I can select Bootloader and perform some basic Fastboot commands, but now I am S-On again, I cannot even reflash a new recovery.
I cannot ADB into the machine so can't re-root using unrevoked or any other method I've seen here to gain root back to try and do stuff again
At the moment I have a very expensive lump of useless electronics and have spent a huge amount of time researching (including most of this thread) to try and find a solution. Any assistance would be greatly appreciated.
I attach an output of fastboot diagnostic in the hope that will help.

hi my desire is a T-mobile so i made a gold card, with this card my phone says safe to remove sd card... is this normal?
now i tried to run the utility but it was not able to send the downgrade rom to sd card
it says failed to copy file : permission denied..
and i cant access my sd card with card reader too! what should i do?
Edit : problem solved

Hi Teppic! Do you think there is a chance to update this tool to downgrade Desire from official Gingerbread to Froyo? I was fool enough to install official RUU and now I lost root, s-off, everything. I'm stuck with a stock phone, no memory for programs, miss my custom cm7 rom 
.
Best regards,
Cristi

After having much trouble with various RUUs and USB error 170 and 171, this finally works for me... I succesfully downgraded CyanogenMod 7.0.3 with AlphaRev-X S-OFF ... I have Windows 7 64-bit with HTC Sync 2.0.40
Unrooted
Thank you for this guide. Now I can get my Desire serviced.
Just had to install stock Froyo 2.2 before this worked.
Everything is working just great, HBoot was 0.93 and now 0.83.

All four of the download links work fine on my side.. What happens when you try access them?
Hmm... Ok, two ideas here:
1: Goldcard
If you have one, put it in your device and try flash the stock RUU again. This is probably the easiest method for getting around CID errors.
If you don't have one yet, you can create one with this guide.
2: Downgrader HBOOT
From the Alpharev website, download the 'downgrader' HBOOT, make sure it's named PB99IMG.zip (name is case sensitive), copy it to the root of your SD card, and boot your phone into bootloader.
When you load the bootloader, obviously you won't be able to see what you're doing, but here's a basic idea of how to do it blind:
- Load bootload: hold volume down and press power
- Wait approx 30 seconds
- Press volume up once, this selects to install the HBOOT
If this either confuses you or doesn't seem to work, try use the command prompt method explained on the Alpharev website (below the HBOOT table).
Can i use GoldCardTool_0.0.5 ? I already created with this tool goldcard
Via fast boot i got

11*Please note: this utility may not function with some very new froyo releases (e.g. the ARA release) and almost certainly will not work on the official gingerbread release*
This utility will quickly, safely and easily downgrade froyo to stock Android 2.1 (HTC software version 1.21.405.2, radio 32.41.00.32U_4.08.00.09, hboot 0.83), which can then be rooted with unrevoked3. The downgraded ROM is fully compatible with SLCD and AMOLED screens.
You do not have to downgrade to Android 2.1 with the supplied stock ROM. After the process is completed, just cancel the flash and install the ROM you require using the standard RUU method (this utility will prevent the version error you normally get when trying to install an older release).
In other words, some typical uses:
- You have installed an update and want to revert to an older version.
- You have rooted your phone and want to return it to stock (e.g. for warranty or selling).
- You want to debrand your phone, or you have debranded and want to re-brand it.
It runs in Linux, Mac OS X and Windows. Please post your results, even if successful and without any problems. If unsuccessful please post the output from the utility and include which version your phone was currently on (e.g. 2.09.405.8 / hboot 0.92) and the CID that the utility gives you (e.g. HTC__001). If the utility reports that it has failed to root your phone, no harm will be done so long as you stop the process.
Update:
Newer versions of unrevoked3 (from 3.21) can now root froyo ROMs directly, and a downgrade is no longer necessary if you just want to root and install custom recovery, although there appear to be a few issues. If you want to rebrand/debrand your phone, rooting won't achieve this and you can use this method instead. If you cannot get the new version of unrevoked3 to work you can also run this and use the older version (3.14) that works with Android 2.1.
Requirements
A working goldcard if your phone is or was branded.
At least 150mb free on your sdcard/goldcard, formatted as FAT32.
Downgrade Utility (v2.3) - Alternate Link
md5sum: f558a157e154e47331da67aa3c3d0a8b
[Downgrade utility (v2.1) - Alternate Link]
md5sum: 9b218e68068e77840d91c9d5edbf32ac
Process
Previous froyo downgrade options are not really adequate for these reasons:
- They result in a broken screen on SLCD phones.
- They do not run at all on software versions higher than 2.09.405.8.
- They involve manually copying files and manual post-downgrade steps.
This downgrade has none of these problems, and will work on SLCD and AMOLED phones and any version of HBOOT.
The process is simple and requires minimal intervention - just a couple of key presses. A few reboots will take place as it flashes the downgrade, and this is nothing to worry about.
You can run this utility on Android 2.1 too. If your phone is rooted or has a custom ROM, it will be restored to a stock unrooted ROM.
This downgrade is not suitable for CDMA phones.
Further Information
If you want to flash an alternative RUU (e.g. a branded 2.1 release), just skip the downgrade section at the end by pressing vol-down on the phone when the utility has completed. Then reboot the phone and run the RUU you want. If you have an SLCD screen you should be very careful here - most older RUUs don't support the screen.
If you want to run a custom ROM you need to apply the downgrade, and then root the phone using unrevoked3.
On some sdcards the phone might not detect the downgrade file (this is nothing to do with this utility, and it will not harm your phone). If this happens, trying a different card or re-formatting it as FAT32 will probably fix it. Otherwise you can install the same downgrade image directly using this RUU. Note that you can only apply this RUU after running the utility, and it is only necessary if the phone does not detect the downgrade at the final stage.
Linux/Mac Installation
1. Download and extract the utility in a terminal:
$ unzip downgrade23.zip
$ cd desire_downgrade
2. Enable USB debugging on your phone. Ensure 'ask me' is set under 'Connect to PC' setting, and 'charge only'. Plug in your phone.
3. Run the utility.
$ sudo ./downgrade.sh
4. Wait for the process to complete.
If you chose not to downgrade, you can now flash any RUU.
Windows Installation
0. Install HTC Sync (driver required).
1. Extract the downloaded zip file fully (do not just click on the zip file).
2. Enable USB debugging on your phone. Ensure 'ask me' is set under 'Connect to PC' setting with 'charge only'. Plug in your phone.
3. Double-click on the win-down file.
4. Follow instructions and wait.
Notes - Please Read
You should remove the PB99IMG.zip file from your sdcard after completing.
This process will wipe all the data from your phone (except the sdcard).
The downgrade will work on branded phones only if a goldcard is inserted (without one: CID error).
The process will flash your recovery partition back to stock.
The downgrade installs an official (unbranded and unrooted) stock HTC ROM.
The downgrade does not depend on any version of HBOOT.
If the bootloader cannot find the PB99IMG file, try formatting the sdcard as FAT32 and try again.

__________________________
If this has helped you, maybe buy me a beer?2Current version: 2.3
Known bugs:
Some newer phones may fail to downgrade properly with an error during the flashing process. If this happens, try installing one of the latest stock RUUs to recover.
Further Information
Backups
Downgrading requires a full factory reset, which is automatically performed as part of this process. There are various apps to help with backing up data from your phone. For example, 'SMS Backup & Restore' is a simple app that will back up your text messages to your sdcard and let you recover them later. You can back your contacts up using the People app (menu, and then 'export to SD card').
Recovery from broken screen
If you have previously run an RUU or tried an older downgrade method and your SLCD phone's screen is now disabled, the easiest way to recover is to run the official froyo RUU to upgrade. You can then either stick with official froyo, or downgrade to a working Android 2.1 release using this tool.
Other HBOOT?
You do not need a lower version, and installing a lower one will break SLCD phones. See this thread for information about this.

Please include as much detail as you can, with at the very least any errors given by the utility. Also include the CID provided by the utility.
