Thanks for the reply. Well the flash gods must be watching over me because I am working on the mk5 4.3 that was out there. I did do a lot of reading (two days worth) and nothing I read covered tri-band and I was already in a pickle with not being able to boot all the way to the desktop. That's what I get for not asking first when I couldn't find any info on this model phone before trying to upgrade it. Wiping cash, data, system, dalvik, and internal did not work unless I need to restore first then wipe all that stuff. I do at least have an external sdcard installed though so I am good there. Samsung does have the version 4.3 for this phone but Samsung Smart Switch will not let me update since it sees that I am already on 4.3. It working so I guess I will leave it alone.
