This is weird...
I bought a used XV6800 in may; the guy i got it from said he got right when it came out in like december of 2007. So peeblo flashed the sprint rom with not issues what so ever; unfortunately my phone was destroyed 2 weeks ago so i got another one from insurance and when peeblo did the update with the sprint rom on my new phone, the internet would not work and i coulnt make any calls. So we went back and tried uploading the sprint rom again only this time he downloaded from another source but for some reason it would always stop at 11%!
