Have you tried this...

I think you need Step. 7 onwards if you have read the tutorial, as you can already FTP/Telnet your box?
Step 7
Now let’s go to transfer the necessary files to the box using FTP
To do this, we connect with our favorite FTP client (I use filezilla). You have to enter the IP address we got on previous step. The user is root, and the password is azbox, as usual. Copy files (Files are in the Files folder of this tutorial):
backup_kernel : Copy it to /MMP on the box
update : Copy it to /tmp on the box
Step 8
Return to the putty windows, where it asks login and password.
The user is root, and the password azbox.
Type:
cd /tmp (We move to /tmp directory)
chmod a+x update (We give the file run permission)
./update /MMP/backup_kernel (start restoration)
The process will begin, and will show progress.
When the process completes, the decoder will reboot, and will come to life!
We have 100% operational box with the original firmware!
Now, we can flash the firmware we want. Don’t forget to make a “Format Application Area” to clean up remnants of previous firmware
