Need Help with ENABLING 900 GSM Band on E398

[Whi$keY]

Hello everybody !
First of all I'd like to introduce myself !
I'm Alex and I'm 19.
I've bought myself (again) this E398 cause the last one I had (4 years ago) broke.
I already own touch phone, but I so loved this one that I bought it new again from Ebay.
Now the phone is unlocked, works on any operator etc, but the problem I have is that my operator operates under 900 Mhz.
Now I tried already the
10*0*3 code to enable it where it says SUCCESSFUL but unfortunately it doesn't enable it, and I can't use my network. It always says No Service/ Emergency Calls only, and when I go to the Networks Setup, I can only see 800/1900 & 850 , and i need 900 Mhz GSM.

So if someone could tell me how preferably (step by step) and give me the exact program to do it with, the firmware file etc, I would really be grateful and will give back the favor for sure !
Thanks in advance all,
With regards
~Alex

You need to flash your firmware to get a quadband gsm.
download my motomix,just click in my signature.
and download flashbackup 3.xx also with motorola drivers from my 4shared.
you only need to do flashing your phone using flashbackup 3 with motomix to renew your firmware.
you can ask me more for your problem.
