Huawei Ideos U8150 Currently displays the standard opening screen when turned on but does not respond to swipe to open. I have loaded an sd card with dload with includes update app (180MB) and userdata.hwefg. I've then pressed vol up + stop(end/red) + power on buttons. No result. Can the capacitive function be restored in any other way? Do I have to accept that this phone is now useless ? A brick ?
