Sold TP2 w/SsS-ROM 2 & now won't activate

[Mr.Gadget]

Help!

I sold my TP2 to someone. It is only a month old and had the SsS ROM #2 on it. It worked great for me. I overnighted it to the buyer and she says she could not activate it. She took it to Sprint and they said it was "fried".
I think they did not know what they were doing...?!!
I would like to have the buyer re-flash to stock Sprint ROM and retry activation over the phone through Sprint (not the store). I am downloading "1.21.651.3_RS_1.96WF_NV_SPCS_1.42_0430_PRL60652_s hip.zip". Sound like I have the right stock one???
Does this sound reasonable?
Any reason why she could not activate my old phone while on SsS ROM?
I have a Hero now which replaced the TP2 just last night.

Help! I may have to refund her. No problem really, but I think the phone is fine. I just need some advice.
Thank you!!!
