ancient_one,

I have exactly the same problem. I also really like the cm6 ROM--except for this problem. I have had my hero since June 2010. When the hero was first released, it had Android 1.5. Picture messaging did not work on it until in August 2010 they released RUU_Hero_C_ACG_2.36.556.1_signed_release. Picture messaging worked after that.

That is probably the ROM that came on your hero. Well, after rooting and installing CM6 everything got better. No more dial lag, easier and more accurate input, but not picture messaging. I remember after the switch to the 2.36.556.1 ROM there were some manual changes that had to be made with a customer support person. It seems I had to dial a 5 or 6 digit number (seems like the number was mostly 7's and 8's) and change some values before picture messaging would work. I wonder if those setting were lost when I flashed CM6 and if another call to CWW support to check those values would help.

I have not done that yet because I dread the "you should not have done that, we can't support your phone anymore" speech.

If others have insight on this problem, I also am all ears!

Thanks!

I have the same problem on my rooted Hero. But I'm not running the same ROM that you are. I found through trial and error that if I disable Wifi then I can receive and send MMS. Then after I get the MMS I turn Wifi back on. Not sure why it works but it does. Good luck.

 

same problem with mine till i installed NFX Hero Rom
