How do you change phone ids (ESN, MEID, IMEI, etc) ? topic

I got the Sprint HTC One M8 (HK) with the intent on bringing it over to Ting which accepts Sprint devices. Issue is, the One is carrier locked via the IMEI until April, one year after the release date. So that was a bust. In the meantime I have a Fascinate with Verizon, that I can use as a donor phone for all its info. Thing I am having issues with is understanding what else needs to be changed to use the phone with Verizon. I read something about the radios need to be flashed and then while I can find the IMEI and MEID, and I can use fastboot to write my own, I cannot find anything for ESN or the MIN(MSIN). That plus the activation number, I assume will dial to Sprint not Verizon, so I'm trying to figure out what else this would entail. I will back up everything, since once April comes around, i'll switch to Ting, but until then, I'd like to enjoy my new toy.
