Probably try to put the fastboot from your sdk folder in copy, paste it into system32 or SysWOW64, I never got fastboot to set properly right but that should make work, unless not, get the usb drivers to sync then try fastboot method again
Do us a favor, open up your SDK\Tools folder, and just make sure there's a "fastboot.exe" there.

[HELP] Can't ADB in fastboot

I've been trying to update my phone to a jelly bean rom and when I try to flash the kernel it says no device found. But when ever I check adb devices everywhere else it appears. Any help for fixing this?

extract laf.img from your stock firmware or the one u are running and run this command in fastboot from command prompt
Code:
fastboot boot laf.img
you will be in download mode. Not a big issue dont worry.

you may have knowingly or unknowingly done these steps thats why your download mode is missing. Google on how to extract the laf image put it in your ADB folder . Then run the command i posted above when in fastboot mode, the screen will change from fastboot to download mode . then reflash stock rom . everything will be fine.

Ok so from this thread : http://forum.xda-developers.com/zenfone2/help/how-to-upgrade-cn-version-to-ww-t3101556
I saw this : fastboot flash fastboot droidboot.img - droidboot.img is fastboot, and if you somehow will flash corrupted image, you won't be able to boot to fastboot anymore. Thanks to sorg
Is there ANY way to fix that ? Mine is broken and I CAN NOT : root/update recovery/enter bootloader
Basically i am STUCK on the firmware I have and CAN NOT do anything on this phone other than factory reset it but thats just about it.
Search for flash_image. I used it to flash recovery from running system. I suppose it can be used to flash fastboot too.

The phone HAS RECOVERY does NOT HAVE BOOTLOADER
Read entire message. I wrote that this tool probably can be used to flash fastboot too.
You can also try "dd" command from busybox. Check sticky section in Zenfone General forum how to use it.

You shouldn't mess with stuff you don't understand
If you have recovery, can you get to recovery menu?
Droid on back with error underneath and where you have to hold power then up volume to get to recovery menu.
Ok, here is link to flash_image tool.
http://forum.xda-developers.com/showthread.php?t=902493
I used it to flash recovery on HTC Sensation, but it should work with fastboot on Zenfone too. The command should be "flash_image fastboot /path/to/droidboot.img"
I'm not sure if it will work, but you already have messed up fastboot so this shouldn't make it worse
The second option is "dd if=/path/to/droidboot.img of=/dev/block/by-name/fastboot" or "dd if=/path/to/droidboot.img of=/dev/block/mmcblk0p3" as fastboot is the third partition. You can execute this even in terminal emulator on phone. Of course I haven't check it, but it's listed in general section to flash recovery (fastboot is just another partition, so it should work too).
About going to recovery maybe you can type " reboot recovery" in terminal emulator or from pc "adb reboot recovery". I'm not sure if it uses fastboot to boot into recovery but it's worth trying.
