i received my fdd redmi note 2 today. i upgraded to the latest developer rom but then my imei numbers were erased. i used a guide to bring back the imei and it worked, but now my phone only works when i use 2g. when i change in settings to lte or 3g, the signal disappears and i can't dial or receive calls. i didn't try to put in a sim befroe the upgrade so maybe 3g was never working. is it possible that they gave my by mistake the tdd version?? i go to engineer mode and it appears that band 1, 3 and 7 are available. i tried to use mi falsh and flash original fastboot version, but nothing works. anyone knows what to do???
