Even if the P/N and the SKU are the same?there is always risk cause card can look the same, labeled the same but use different firmware anyway. you're pretty solid, but still a risk. Not too unusual that guys go ahead and flash and notice rom is incompatible and stand without any working rom.
Are there any other distinguishing characteristics I can look for on the card to verify? It was shipped with the box, software, cables, etc. so maybe that might help to ID the card as well, yes?
