I recently helped out a friend who was having issues with their RAZR being unresponsive. I used SafeStrap to install SlimKat, but they had so much stuff on their Phone that I ended up putting in place of the stock rom. Almost everything works fine and the phone is much more responsive and useful. The only issue is that they can not send or receive MMS Messages. With the stock Messaging App they were getting APN not specified. I tried to set up a new APN under settings but the option is greyed out. I tried to replace the apns-conf.xml with one I found searching, which didn't work and I even tried to go to 8SMS and that still didn't work. I'm not totally new to Flashing ROM's, XML or moving data to and from Android, either via PC or with Root Explorer, but I'm used to working on my Galaxy not this RAZR so any help would be awesome. If there is a good fix for this I would really appreciate anyone helping me through it.
Thanks in advance.
