Hum... well now that I found that Verizon would just accept my PPC-6700 (from Sprint) with open arms, I've been tinkering around with the ideas of getting Verizon to allow me to subscribe to VCast service on it (so I can get my "emergency data" plan like usual - Bluetooth tethering). God knows I'm not gonna pay $40+ per month for something I'll only use once in a while...
So "method" (involving ESN and one of my other VX8300's) aside, I now have VCast subscribed on my Apache, and service (phone/SMS) works great. Just for one small (big, rather) problem! Whenever I try to connect to the internet via "Cellular Line", I get a message from Sprint saying "Error Code: 67 / Registration failure. Your PCS Vision username and/or password may be incorrect. Please try again".
How on earth did my Apache even remember anything about Sprint? It's been fully flashed in every corner of the device... there's no traces left of Sprint that I know if (I updated radio/ExtRom/OS with the latest Verizon XV6700 ROM, first time I ran it I let it fully "customize", then I hard-reset it and selectively installed customizations that give me features instead of stripping...). The only trace I found was in nvm_htc which had a Sprint URL in it.
The OP's post regarding editing nvm_htc is very very vague and I don't exactly understand what needs to be done in the hex editor (which I'm plenty proficient in using, btw). I found SPCS_001 in the file and replaced it with "11111111", but I'm not sure if that's what needed to be done, as I still get the error.
