You really should seek help on the proper device forum section, as nuances to the device can actually mean that advice given by EVITA owners can be incorrect or even harmful on the ENDEAVORU.
But the nature of the particular question, likely
applies to either device (although I can't guarantee it). I don't think you will be able to restore an SMS backup made by the Sense feature on any non-Sense ROM (at least not easily).
Do you still have access to the Sense nandroid that contains the original SMS messages? If so, my recommendation would be to restore that nandroid, run SMS Backup+ to sync your text messages to your Gmail. Then go back to whatever ROM you currently desire, and restore the texts using SMS Backup+.
SMS Backup+ is what I have been using for a while now. Its a simple program that works pretty flawlessly to backup your SMS messages to Gmail. So it works across virtually any manner or ROMs or Android phones.
