My text messaging started acting weird lately; all of a sudden I was getting late messages, or multiples of one message. And then I wasn't getting any texts at all. This was while I was on Definitive rom, and had not changed any settings or my messaging app (chomp) for a good month beforehand. So I decided to flash FireKat for the DE, and it seems to have worked, but I wanted to set the settings for MMS as suggested in chomp, and I find that the Access Point for Verizon is un-editable. I tried editing the build.prop as suggested for the Note 2--obviously, it didn't work, I lost my Access Points entirely, and my network went to hell--and after a reflash, I'm back to where I started. Does anyone have any idea how to edit access points on the DE?
