First off, I know this is "questionable" in some places. If you're not comfortable discussing it in public, my email is burgess AT nightscapetech.com.
I picked up a used Sprint Motorola Photon from ebay, the phone still has a good ESN (so I own it outright, and the previous owner has no debts to Sprint). I started populating it with the profile information from my Brio (See this thread: https://help.ting.com/entries/21495371?page=1). I was able to write all the information except for the ESN and the MEID, both of those simply revert back to their original values. Is thee any special trick to getting the ESN and MEID to write properly? I have been using the DFS tool, I only have the free version of CDMA workshop, but I might be willing to pay for it if someone confirms that it works for this, or other motorola phones.
