This is an update, finally I got it works and solve my problem:
the reset procuder as follow: (This I used for CloudStation CS-X2)
Bring the unit to EM mode which will put the NAS in a state where it is detectable on the network and allow us to reset the password/settings to allow access to the unit again.
- Power the unit down (disconnect the power by pulling out the power cable while the unit is ON).
- Reboot the unit, if the power led is still flashing more than 60 second's from the start, disconnect the power immediately and retry.
- Do this until the unit's power led is constant 50 second's after the start and the unit is in EM.
Please note it can take a number of attempts to bring the unit to EM mode.
Once the unit is in EM mode run the file shared by Davo (LSRecovery.exe) and it will do the rest, Plz note: this file is not working one windows 8 better to use compatabilty mode and select Windows Xp SP3)
I would like to first to thank my God then thank Customer support for the EM procedure they sent me by mail as well as thank Davo for his support and share.
This procedure helped me reset the NAS password and saved my data.
