SDK is a spammer. Hasn't written a single sensible post. Just meaningless drivel. Not sure if it is a person or a spambot.
As to your problem: Different RM-model numbers means different hardware, which means that firmware for another RM-model is likely going to be fatal to your phone, if you try to flash it.
