I have a sprint marquee flashed to boost. Can't update profile. I have rewritten the nv files from my incognito. Written ha and aaa secrets a few times.network shows up aslong as I don't update internet workd at 1x I see 3g for a sec then back to 1x. Looked at my phone's info and it shows I'm still on sprint network. If I update network shuts off and I get error code 67. Any solutions would be nice. I'm growing my hair just to pull it out because of this.
