Im using the fastboot method to flash the original sprint RUU in zip format.
I used:

-fastboot oem rebootRUU
-fastboot flash zip (or HERCIMG, HERCIMG.ZIP, etc etc)

But i keep getting "Error: cannot load "" or whatever i type.

Stuff i tried:

*Unlocked bootloader to s-off - still wont let me flash and zip files from the bootloader. I'm 100% ive done this before several months ago, and i even used the same HERCIMG file that i left in the /sdcard main directory.
*Delete the old HERCIMG and download a new one from the dev section of the hero forums.
*Manually placed in root of sdcard by mounting the sdcard on my computer.
*Used adb to push the HERCIMG file to the root directory of sdcard

Anyone can tell me whats going on?
Also right now i have CM7, bootloader 1.47 unlocked.

Maybe i have a bad version of fastboot.exe? I copied it from /tools/ folder of android sdk and placed it in /platform-tools/ since it needed adbwinapi.dll which is located in that folder along with adb.exe
Thanks for any help

Ok guys. I have no idea whats up, but eventually i was able to fix by loading the unlocked bootloader and running the RUU.exe from windows. Still wasnt able to flash the HERCIMG.

I had a huge issue with HERCIMG not working for me. I noticed that I had and changed it to HERCIMG.ZIP - make sure it is all caps on your sdcard, how it gets there does not matter, I copied it in windows. Next, you must boot into bootloader - there are many commands, but it has to be a white screen on your phone and text will some point, it will ask you what you want to do with the file...This is all done on the phone. You must have s-off too. If you are not using the ENG hboot, I dont think fastboot will work, btw (and the eng hboot is 1.46)

Yup. Flash darchs eng-spl and you should be good to go. Oh and you have to take into account your radio/baseband ver. If its .29 then you have to flash it a certain way or downgrade your radio then flash it then hercimg your current radio again.

Well the last time I checked you have to flash it from recovery. If you search the hero dev section for it I'm sure you wil find it. Also I'd highly recommend Flashing it with Ra1.6/1.7 or Cwm2.5 and remember to check your baseband/radio version. If you can't find it let me know and I'll post it after church. But you should read as much as you can about the mod to get a better understanding of the risks and benfits of the mod.

Don't forget that your SDcard has to be formatted to Fat32 so the bootloader can find it.

When I use/have used any, I have never done it through fastboot, I have always done it by using the H-Boot screen. The cannot say " (so don't name the zip file with a .zip in the name- check the details of the file to make sure).
If you are in the bootloader, press the volume button down to get into H-boot from the Fastboot or restart the phone (press volume and start button at the same time).

If you used Regaws to become S-off, then I know the H-boot method will work fine. As far as using fastboot commands, you would need to flash Darch's Eng Spl mod that changes the bootloader to 1.46.2. There is a thread by jasonmaloney that has to do with flashing an RUU from fastboot without being S-Off. This needs to be done from Windows, that's why jason includes fastboot.exe along with the RUU. Is the RUU you are using all images, or are there other files as well (binary types)?
Good Luck
