I flashed a Huawei (Vodafone) K3765 modem so I could use it with my MTN prepaid sim card but I keep getting an error message saying 'Error 31: A device attached to the system is not functioning'. All other sim functions like sms and USSD work fine but its the data connection that's refusing. I'm not sure if I'm messing up the profile settings (profile name / APN / access number) or its my computer with the problem. I have an i3 HP running Windows 7 Enterprise. An assistance will be appreciated. Thanks in advance.
