I have downloaded the SBF through TBH app and flash the SBF using RSD Lite 4.9. When the procees is 99%, windows show that new device 'Flash MDM6600' is connected and prompt for the driver. But I do not have the driver (or may be it is in my computer but I do not know where it is). A moment later the process become 100% but the result is failed. The status show that 'Failed flashing process. Phone: Error switching phone to BP Pass through mode (0x70BE); phone disconnected'. Can anyone send me the driver? or tell me the solution? Thanks.
