[HELP]Location of default.xml on Kyocera Brigadier?

Hey there,

I was trying to get rid of the "unknown sim card" notification on my Kyocera Brigadier. I got it running on AT&T, and it works great, I just constantly have that notification saying it's an unknown sim card, which is kind of annoying. I found with other phones there is a default.xml file located in the system/customize/acc folder, that can be edited to get rid of this error. The problem is, on the Brigadier I don't have a customize folder in the system folder. And the explorer (droid explorer) i'm using doesn't have a search function.

Another question is, if the phone doesn't have this file at all, if I created a customize/acc folder and placed a default.xml file in there, configured so that the sim card wouldn't be unknown, would the phone read and recognize this?

Edit: I downloaded ES Explorer and searched for default.xml, nothing turned up. So I guess the question now is, is there another file that does the same thing as default.xml, or if not, could I create me own default.xml file and have it read by the system?

Thanks in advance!

Kyocera XTRM C6721 with SYS APP VIRUSES - Framaroot success, still not rooted

Kyocera Hydro XTRM USCC-C6721

The viruses are manifested as system apps and cannot be deleted/uninstalled. I have wiped the phone in recovery mode, factory reset it, removed the sim card, tried rooting it in various ways... At this point I have to make myself give up and ask for help before I go nuts!

Framaroot finally started reporting success, but I've tried 5 or 6 different versions at least twice each (all attempts and different versions successful), but upon rebooting/restarting, the phone is not actually rooted. It's not rooted before restart, either (root checker). Other options have failed (kingoroot, Cydia Impactor, etc).

I've read a million forum threads and websites, tried for hours and hours, but I'm still not getting anywhere.... I have seen mention of flashing/roms/scripts but I don't know anything about that and need better instructions. Please help!
