Here's what you need to do:
Download the QLD Tool folder from the Dropbox as a zip file.
Unzip the contents in C:
1. Press the volume up button and keep holding it after five seconds(approx) connect the USB cable(The other end should always be connected to the computer) while holding the volume up button until you hear a ding sound from your windows pc. Now open device manager and check for driver listing in the "Unknown" section named "Qualcomm CDMA Technologies MSM".
If the device is listed as “Qualcomm CDMA Technologies MSM” under “Other Devices”…
a.Right-click on it and select “Update Driver Software”.
b.Select “Browse my computer for driver software”.
c.Select “Let me pick from a list of device drivers on my computer”.
d.Click “Show All Devices” and then click “Next”.
e.Select “Have Disk”.
g.Select the folder containing the drivers. For us, the drivers will be located somewhere like “C:\Streak\repairtool\QDLTool…\Drivers\Driver_2.06 7\Win32”. (Without the quotes, of course.)
h.Select “qcser.inf”, and hit “OK”.
i.Under “Manufacturer”, select “Qualcomm Incorporated”.
j.Under “Model”, select “Qualcomm HS-USB Diagnostics 9002”. Select “Next”.
k.You may get a warning. Hit “Yes” if you do.
l.Once Windows installs those drivers, hit “Close”.
m.Your Streak should now be listed as “Qualcomm HS-USB Diagnostics 9002”, under “Ports”.
2. Download the adb driver and install it. To check whether the driver has installed properly. power on the dell streak holding the camera button simultaneously. streak will give a white screen with fastboot on the right most corner. Enter fast boot mode by tapping on it and the screen will tell that it is waiting for a usb connection. Now connect the streak to the PC. You should hear a ding and the device manager will show "Android 1.0" if the drivers are installed correctly.
Now we have the pre-requisites for the diagnostic mode and fast boot mode.
Run the QDL tool. Now press and hold the volume button while connecting the computer. If the qualcomm drivers were correctly installed you will see that name(qualcomm …) in the port setion.
Click Run. This tool is going to take a lot of time. Here we are carrying out diagnostics and also installing Froyo with BB 306.
It will reboot several times since it has to enter fast boot mode to install recovery and flash the rom. If at the end, all the logs turn out green, Congrats, you have repaired your device. Exit the tool, unplug the device and reboot.
I successfully revived my Streak using this method. Wish you all good luck.
