however onto the bug i have experienced,
currently atrix4g running kitkat bigpart build v2, CM version is cm11-20140813, adroid ver 4.4.4, basband is N_01.77.38p, kernel 3.1.10 droid@ubunto-00#1 wed aug 13 02:58:23 utc 2014, build number cm_olympus-userdebug 4.4.4 KTU84Q 53bdf40312 test-keys, carrier ATT US, also my runtime is DALVIK, and SElinux is enforced at the time of the bug.
Most everything runs smooth and without problems havent ran across any force close events thusfar been running this since yesterdays release, battery seems to last a good deal longer with everything disabled and all is well except for one thing when i connect to my mobile data, my mobiledatanetwork carrier is set to the standalone ATT option like ive had in past roms by default and everything worked, i can send mms messages and they get sent just like normal, however when i recieve an mms message i cannot download it, auto-retrieve on or off, ive tried different APN connections such as ATT LTE and ATTPHONE all either have no connectivity with the att servers to send or recieve mms except attphone and the standalone ATT. Hope this contribution helps in some way.
EDIT:Resetting the APN settings, making a new set, inputting different values for different networks(ATT3g/ATT4g etc) does not work, the fone takes the update and saves it however mms messages are still undownloadable, still can send them no problem can recieve the download tag for an mms recieved, click download and it sits at downloading, after u click download though it does switch to 3g quickly adn then back but with no update to the message so i am unsure as to whats going on internally.
