Lanvo LTE bricked

[fitz]

Hi to all. My Lanvo L200g LTE MTK6582 lost some functionality (home button etc) after uninstalling an app locker. Factory restore did not fix the problem. Have been experimenting with sp flash tools to try to load a different ROM but have managed to completely brick the phone instead. I think I have hit the format button. Now no indication of life except a repeating beep from pc when usb'd and the occasional windows message of usb device malfunction. Flash tools =error message, droid tools does not see the device and it does not show up in windows xp either other than as an mtk port.

Is there a way of approaching reinstalling an OS on what appears to be now a completely raw device? Help in re-animating my phone appreciated
