Do I really need to.. ?

[xtremngl]

Im stuck at this step:

*Get XS++ and a proper MAIN firmware(use same version as your FS !)

I cannot find my MAIN fw in the following link http://forums.se-nse.net/index.php?showtopic=7699

If you check it has no link. This is in the event that I wish to keep

Operator: AMERICA_2
CDA: CDA102494/60 R6A
Firmware: R4DB005

Where can I find this main or the updated one?

Is R4EA031 the laster w810 FM and MAIN version?

EDIT: I just found out R4EA031 is the lastest version as of 2006-09-25.
And there is also R4EK001 version which I suppose it hasn't been released.

Where can I find AMERICA_2 and the CDA listed above?
