 IN BELOW INSTRUCTIONS, IF USING MAC / LINUX TOOLS, ALWAYS
 preface adb WITH "./" and ALWAYS preface fastboot with "sudo ./"

 For example:

 ./adb devices
 ./adb shell

 sudo ./fastboot erase cache
 sudo ./fastboot flash zip PB31IMG.zip

Downgrade

1. Turn on "USB Debugging" on your phone: Menu -> Settings -> Applications -> Development

2. Connect the HTC Incredible to your computer & set the connection mode on the phone to "Charge Only"

3. Open a command prompt or terminal and navigate to your directory with adb and the other files.

  You can also hold CONTROL+SHIFT while you RIGHT-CLICK on the
  folder you extracted the files to, and select "Open command window here"

4. Enter the following commands (in bold):

adb devices

 If you see your device listed, continue with the rest of this guide

adb push flash_image /data/local/
adb push mtd0.img /data/local/
adb push zergRush /data/local/
adb shell

 AT THIS POINT YOUR PROMPT SHOULD BE "$ "

cd /data/local/
chmod 755 zergRush
./zergRush

 Let it do it's thing, until it kicks you out of shell, then re-enter shell

adb shell

 AT THIS POINT YOUR PROMPT SHOULD BE "# "

cd /data/local/
chmod 755 flash_image
./flash_image misc /data/local/mtd0.img

 Verify there were no errors - otherwise abort and join IRC for help

exit
adb reboot bootloader

 Your phone will reboot to a white background, and say "FASTBOOT USB" at the top
 In the command prompt/terminal window, type the following:

fastboot erase cache
fastboot oem rebootRUU

 Your phone will say HTC in big gray letters

fastboot flash zip PB31IMG.zip

 Don't worry if the following shows up in your command window

 FAILED (remote: 90 hboot pre-update! please flush image again immediately)

 If so, you'll need to type the above command a 2nd time:

fastboot flash zip PB31IMG.zip
fastboot reboot


When this has finished, your phone will be back to running Froyo, in a factory stock condition.

You are now ready to run unrEVOked v3.32, and get radio S-OFF, the best S-OFF there is.

On Freenode IRC, join: #unrEVOkedtest, for additional support.

Here are the steps to run unrEVOked:

1. If you are running Windows, you need to install the unrEVOked modified HBOOT Drivers.

 Follow the directions Here: (http://unrevoked.com/rootwiki/doku.php/public/windows_hboot_driver_install )

   ( The driver needed can also be downloaded from: http://downloads.codefi.re/zanzibar/Tools/android-usb-driver.zip )

 (Come Back to This Page When Done.)

2. Boot your phone into running mode, and checkmark these two items:

  Turn on Unknown sources (Menu -> Settings -> Applications)
  Turn on USB debugging. (Menu -> Settings -> Applications -> Development)

3. Plug the phone directly into the computer's USB Port.

  Do not use a USB hub, and plug it in the back if possible.
  Choose the option "Charge Only" on the phone, not "HTC Sync" or "Disk Drive".

4. Download reflash-package from: http://www.unrevoked.com/recovery/
     ( You can download the Windows executable from: http://downloads.codefi.re/zanzibar/Tools/reflash_package_v3.32.exe )
     ( You can download the Linux executable from: http://downloads.codefi.re/zanzibar/Tools/reflash.tar.gz )
     ( You can download the Mac executable from: http://downloads.codefi.re/zanzibar/Tools/Reflash.dmg )

  For Windows, run reflash-package.exe or reflash_package_v3.32.exe, as Administrator)
  For Linux/Mac, run reflash as root ( sudo ./reflash )

AFTER you complete the root, you should use the commands listed in bold below to flash the file PB31IMG_Incredible_C_Gingerbread_S_VERIZON_WWE_4.06.605.3_Radio_2.15.10.07.07_NV_1.70_Hboot_6.02.0420_CWM-5.0.2.0.zip to get the latest version on your Droid Incredible, along with a custom HBOOT and ClockWorkMod recovery installed. The custom HBOOT will give you many extra fastboot commands, normally only available with an Engineering HBOOT.

Boot your phone fully, and do the following:

Turn on "USB Debugging" on your phone: Menu -> Settings -> Applications -> Development

In your command prompt, do this:

adb reboot oem-78

 Your phone will reboot and say HTC in big gray letters

 In the command prompt/terminal window, type the following:

fastboot erase cache
fastboot flash zip PB31IMG_Incredible_C_Gingerbread_S_VERIZON_WWE_4.06.605.3_Radio_2.15.10.07.07_NV_1.70_Hboot_6.02.0420_CWM-5.0.2.0.zip

 Don't worry if the following shows up in your command window

 FAILED (remote: 90 hboot pre-update! please flush image again immediately)

 If so, you'll need to type the above command a 2nd time:

fastboot flash zip PB31IMG_Incredible_C_Gingerbread_S_VERIZON_WWE_4.06.605.3_Radio_2.15.10.07.07_NV_1.70_Hboot_6.02.0420_CWM-5.0.2.0.zip

 After a bunch of status messages appear on the screen,
 and you are returned to your prompt, continue...

fastboot reboot

When this has finished, your phone will be back to running 4.06.605.3, with all the latest radios, etc.

The final step will be to do the following:

Download Superuser-3.0.7-efghi-signed.zip (md5: fc462fa0630379edbe10006b1d19d9b1). Do not extract any files from the zipfile. Place this zipfile on your sdcard, and install it from within ClockWorkMod recovery.

The file is located here - http://downloads.codefi.re/zanzibar/Tools/Superuser-3.0.7-efghi-signed.zip

Good Luck!
