Did you press these keys before power on and keep pressed while the unit boots?

I confirm you this sequence works properly. ( I done it a year ago )

Best regards,
Flavio

I think I tried it like this...I can try again...

Didn't work
I powered it on with those keys pressed...
First the display says "ERROR Wave/Expansion memory damaged"
After pressing those 3 keys simultaneously again, I'll get "ERROR Wave/Expansion memory damaged" with "CONTINUE " and "TRY RECOVERY" buttons
after trying "TRY RECOVERY" I'll get "Function error !"

Time to follow the instructions....
Please, contact Customer Service.

But....And if you press CONTINUE instead of TRY RECOVERY...

And if you install from another USB drive ?

✅ Roland Fantom – Memory Error: Summary of All Steps to Try

If you get the “Wave/Expansion Memory Damaged” error on a Fantom 6/7/8, try the following steps in order:

---

1. Forced Memory Format
This is the official first step.

1. Turn the Fantom OFF
2. Hold SHIFT + EXIT + ENTER
3. Turn the Fantom ON while still holding the keys
4. Keep holding until the format screen appears

If the format completes but the error returns, continue below.

---

2. Factory Reset (if you can reach the menu)
If the keyboard boots far enough to access the menu:

1. Press MENU
2. Go to UTILITY
3. Select FACTORY RESET
4. Confirm and reboot

If the error appears before the menu loads, skip this step.

---

3. Reinstall the System Firmware from USB
Sometimes the internal memory map becomes corrupted and needs a full OS reinstall.

1. Download the latest System Program from Roland’s website
2. Copy it to a USB stick
3. Boot the Fantom in update mode
4. Reinstall the firmware completely

If the error still appears after a clean reinstall, continue.

---

4. If all resets fail → Likely hardware failure
According to Roland tech support and repair forums:

- Some Fantom units have faulty internal flash memory (NAND)
- When the chip cannot be formatted, the error keeps returning
- The only fix is main board replacement at a service center

This happens rarely, but it does happen.

---

✅ Short conclusion
If forced format + factory reset + full firmware reinstall all fail, the internal memory is physically damaged and the unit needs service.
