No custom roms working on my ATrix 4g ATT model

So,as the title says after I flash any custom rom(cm9,jb,gb) my screen freezes at the Motorola Dual Core blah blah...I know the big 3 wipes rule and i did this every time,the only rom i have managed to flash and wich is working is nottachtrix 2.3.6...i also have 4.5.131 ATT en.US but from other providers (Cosmote in Romania) i rooted my phone,unlocked and everything...i can't get over this,can someone help me ?
P.S And smth else,i can't use my data service on Cosmote(did the apn thing) i can use it on Orange and Vodafone but on cosmote it's not working,can someone tell me why ?
Regards,
Try updating recovery, or better use the recommended recovery for the Rom you want to flash...
Thanks dude,seems like that was my problem

Does your sim card support 4g? If it's too old, there is a chance it doesn't
