[Q] Help me on fastbooting :(

I've downloaded all the things that im supposed to download. There's recovery image (for froyo 322) and update for froyo 322 and the fastboot file.
Firstly, i made my dell streak onto Fastboot mode.
Then i connected it and it said "Fastboot_Mode"
After that i open Command Prompt and open fastboot.exe which was located in fastboot file
But, when i type "fastboot -i 0x413c flash recovery (my recovery image file name)" it says "fastboot is not recognized as an internal or external command, operable programme or batch file"
Im on windows 7 home basic. Someone please help me. My phone's still in fastboot mode till now
You need to make sure you change the directory of the command prompt to the folder your fastboot.exe is in. Then use fastboot.exe instead of just fastboot in the command

[Q] 10.1v Device not found

Yes, I have read every single thread about this issue and I have tried all steps including downloading new drivers, removing old USB drivers, ...
Yesterday I unlocked my Bootloader using this thread: http://forum.xda-developers.com/showthread.php?t=1064793
Everything went fine and when I boot up my tab I can see the unlocked lock.
According to the thread the next step was following this thread: http://forum.xda-developers.com/showthread.php?t=1079781 (How to get root on 101.v)
I booted my tablet by holding down the Power Button and the Volume Down button. I selected the USB icon and in the left corner I see
"Fastboot USB download protocol"
Bootloader version: P7100BUKC8
Baseband version: P7100BUKDF
Lock state: unlocked
Everything goes well up to the step where I have to type adb push skitzandroid-10-1v-root.zip /sdcard/ in the Command line. When I type this, I get a message: "Error: device not found"
In the aformentioned thread someone else has a similar problem. One person asked if he was still in fastboot? Aren't you supposed to be in fastboot to root your device? He also asks if Clockworkmode is loaded. Doesn't this step come after rooting your device?
When I just open command and type fastboot devices I get a message saying: 'fastboot' is not recognized as an internal or external command, operable program or batch file. When I type "cd "C:\android-sdk-windows\tools"" and then "fastboot devices', it does work and I get a message saying: [serial number] fastboot. Does the fastboot devices command only work if you have a specific folder selected?
This is all so confusing
Thanks for any help

Ray fastboot problem when opening bootloader Solved, can be deleted

Hey guys! I'm a noob, I aknowledge it and I apologize for it.
I've been trying to open the bootloader on my brand new Ray by following the official Sony Ericsson guide found on their website. The problem is that I'm stuck with this step:
# Open a command window and go to the tools folder within the Android SDK folder.
# Enter fastboot.exe -i 0x0fce getvar version, and verify that you get a response back (for example "0.3"). This means your phone is connected properly.
The only answer that I get from command promt is: 'fastboot.exe' is not recognized as an internal or external command, operable program or batch file.
This leads me to thinking that there's not fastboot in the SDK-folder. Why is this? I've followed the guide to the letter, and I've checked several times that I actually did follow it to the letter. Any help guys? Please?
Found the solution after hours and hours of fighting, still not through with all the problems though.
Try flashtool, inside x10 flasher folder you will find the required fastboot and adb.exe and dll for them. Try from there.

Have you installed the drivers for fastboot or ADB? If not you have to do so, and it shouldn't take much time if you use the fastboot gordon gate installer.

Take a backup of your data before proceeding further.
Try this,
Download adb and Koush Universal adb driver and install them on ur pc, always install the driver first and don't install the drivers adb setup asks u to install.
Run command prompt as administrator.
Open the folder in c drive where adb is installed, u can use file explorer for this.
Press Shift+right click and select open command window here.
Enable USB debugging on your phone and connect it to the pc by a USB cord.
Enter command "adb devices" without quotation marks.
If it shows some device connected, only then proceed further.
Enter command " adb reboot bootloader"
Enter command " fastboot devices", if it shows some device to be connected, only then proceed further.
Enter command " fastboot oem unlock".
Ur phone may then ask for final confirmation on the phone screen, select yes.
When procedure completes, type "fastboot reboot" and ur phone will reboot.
U can now use Kingoroot for pc or any other tool for rooting.

Have you installed adb? If yes, then proceed further.
You are in the wrong folder. The correct path should be C:\adb
Then Shift+right click
Select "Open command window here"
