    And thanks in advance for this ROM.
    Does it come with LTE support?
    My initial installed ROM for this device didn't have it so I downloaded a mod which had a modem installed which had LTE band support.

    14s update worked fine but 17s bricked my x500. Took a long time with spflashtools to get it working again. Would rather recommend upgrading to 15s and applying bb72 pack to remove chinese apps. http://www.letv.re/topic/1161-bb72-le-1s-eui-58-015s/
