How did you do it?
In the same way described here: http://wiki.xda-developers.com/index.php?pagename=Hermes_SDCardFlashing
What .nbh file did you use? The one extracted from Original-Dash-ROM?
Can you save the SD-Card on PC with psdwrite/psdread?
Thanks in advance for sharing your know-how

Flash from SD using original TMO rom
This is what I did:
1. OPEN RUU_Excalibur.exe with an archiver and extract files to temporary directory (the file we want is the EXCAIMG*.nbh)
2. Format SD card using FAT32
3. Insert SD card into phone
4. Connect using ActiveSync
5. Rename nbh file to "EXCAIMG.nbh"
6. Copy EXCAIMG.nbh to SD card
7. Disconnect phone
8. Start Manual Bootloader (hold camera key for three seconds and press power button)
9. After quick messages (checking sd card, etc.) you should get "Update SD image? Press power button to download" screen with countdown in bottom corner
10. After timeout you will go to color bars UI
Exit bootloader: hold camera key, wait three seconds and hold down power key also until phone turns off
My phone is not unlocked, so I didn't test with other roms.

SD Flash WM5 works SD Flash WM6 doesn't?
Ok, using the extracted nbh file from the original WM5 Dash ROM, I perform the following operations using the command prompt under windows:
1. Format SD card (FAT32)
2. Rename nbh file to EXCAIMG.nbh
3. copy EXCAIMG.nbh to blank SD card
4. copy any additional files to SD card (cabs, homescreens, ringtones, etc...)
5. Insert SD card into phone and power on while holding down the two softkeys
This method allows me to flash the phone back to WM5, but when using the nbh file from the WM6 Test ROM it will not work. Can anyone tell me why? WM6 -> WM5 works, but WM5-> WM6 doesn't. Is it the bootloader (same or downgrade only) or is it the signing of the ROM, could it be something else I'm missing?

Is the .nbh file talked about the bootloader only (~1.5 MB file) or the entire ROM image (~36 MB)?
can i ask why you would load the rom from an SD card when you state "connect to active sync"? if you have a computer there, that the phone is connected to, why not just use it to flash the rom?
Because my power button is broken and I can barely get the phone into bootloader. While in bootloader, active sync will not connect to the phone so I can flash it via my computer. Thats why I was wondering if I coud flash thru the SD card.
Thanks mate, your info above saved my unlocked athena (X7500) on which I had flashed a wm6.5 ROM which was faulty, and had completely taken over my athena, and refused to flash any other roms.
I have now reflashed with original rom before I try to flash other roms again.
Thanks once again.
PS. The last step does not work with Athena, what works is to simply do a soft reset by inserting the stylus into the reset hole.
Thanks but I still can't do itKeep trying, you are probably holding too much time the power button.
Do I need to release cam key when I press Power ?? or holding it ? Same question for Power button ? I'd know the timer is very important..Funny,I've sitting in front of my clock,count 3,and do it ~ 1k time,mine buttons are nearly broken
