Sprint Flex to ATT, then to Tmobile issue

[yellaboyla]

Hi guys, Have a question;

I took a free LS995 (sprint) and modded per the forum and turned on GSM. Then I flashed the ATTSPRINT rom and edited the APN to get it to work on TMOBILE. The ATTSPRINT rom is on 4.2.2. I got curious and flashed the modded TMOBILE rom from the forums (4.4.2) over the ATT rom. For some reason, now I can't make calls. Checking the Mobile networks, the setting don't look right, but I can't change them.

Just looking for some direction while I search...thx in advance.

5457#* ur model#
OK, I can get into these menus, but what do I need to change?
