What rom or just stock rooted? There were some specific rims that had issues a while back.

Have you tried deleting data etc at menu.settings.manage apps.messaging

Give me more details on ur set up

 

I have seen this posted before but don't recall the fix. Give me some time to find it

 

ok so far after 11 or 12 pages I have found two possible solutions

go through the same steps above and force stop the messaging app and then go open it and try the mms again
and
make sure wifi is off...

 

update prl and data at menu.settings.update software

also check out this thread Transient failure when trying to receive MMS. - HTC EVO? 4G (Sprint) - Android Forums - HTC Community

 

in that case find a stock rooted rom...

go into recovery (nandroid to be safe and make sure your apps all have a current backup) and wipe dalvik and cache , DO NOT wipe data, you are simply flashing over what you have. you shouldn't loose much at all other than some settings, widgets and customization

flash the stock rom , try mms

if it works than most likely you deleted something you shouldn't have

go back through deleting/freezing stock apps but do a functionality test after each one

 

glad it worked!

just a quick disclaimer...if you do experience issues you will want to back up all your stuffs with titanium ...wipe all data, dalvik, and cache and reflash flash.


Most have flashed it over stock with no issues....but he does say a full wipe is best. Fresh is not a stock rom but a custom rom based on stock.


I really don't think you will have issues though.

Glad I could help
