                      i still havent been able to return it to complately normal but it works with hilink drivers on pc too

                    • Hi kamlesh
                      regarding this solution i have correct info here

                      1. First of all, you have updated normal modem to hi link modem, then your modem will be not detected by Huawei Mobile Partner software.
                      2. install huaweri Hilink drivers your modem will get detected
                      3. For those who see their modem locked u can install Russian beeline firmware and it will unlock your modem
                      4. if u recive error code 10 then it is your good luck so dont close that becoz you are one step from repairing your modem keep the error window open it will show the modem as below or as other 2 unkown devices so update then with same name below

                      5. open device manager if u see either then manually update them by selecting from list->>ports->>
                      FC-Application Interface update to huawei mobile connect-3g Application interface
                      FC-PC UI Interface to huawei mobile connect -3g PC UI Interface

                      6. your device will be detected and u can update to beeline firmware

                      7. then download the Download Firmware Huawei E355s-1 (OpenMarket India) and unzip in folder.
                      and it will be repaired

                      finally reset your modem after upgrade and your modem is as good as NEW

            • If not worked, then download latest version Huawei mobile partner software and install in PC, in device manager try to search new devices. If something is coming in yellow in COM ports, that means it is drivers problem, install the drivers manually.

  2. I by mistake updated my Huawei E355s-1 dongle to and web UI to I was not aware that it was meant for hi link e355. Now i cannot use Mobile Partner, the dongle is working though. I have downloaded Firmware Huawei E355s-1 (OpenMarket India) as mentioned in this post but cannot install it as the software is showing “Error 10:Find Port failed”. What should I do now in order to revert back to the previous version? Please give me a way out.

      • In Device Manager I don’t see any yellow or cross marked driver.

        Under Universal Serial Bus Controller I can see – Huawei Mobile Connect-Bus Enumerate Device and other Intel Host controller;

        Under Network Adapters I can see – Intel (R) PRO/100 VE Network Connection and Windows Mobile-based Internet Sharing Device;
        Under Ports (COM & LPT) I can see- Communications Port (COM1) and Printer Port (LPT1)
        I have tried to connect the dongle in other port but after installing usb driver it shows “Drivers cannot be installed properly.Your device might not work properly”
        How do i now install drivers in device manager separately?

          • I have already installed Mobile Partner (showing the latest version) but it does not detect the dongle. Also kindly mention clearly which port no. or name should i change because i cannot see anything like FC-Application Interface, FC-PC UI Interface or HUAWEI Mobile Connect – 3G Application Interface , HUAWEI Mobile Connect – 3G PC UI Interface ,as mentioned in earlier posts, in my Device manager. I have changed the Communications Port (COM1) to Communications Port (COM5) but nothing happens;no yellow or red cross mark beside anything. Getting a bit confused as to what to do.

  3. I have the same problem as these people, my firmware upgrade failed at resuming user information when upgrading to firmware and web UI to Now the dongle only installed the CD mount driver, other drivers won’t install. Both LED on the dongle blinks, I can connect through WiFi to the dongle but the webUI won’t load. When i try it just keeps looping infinitely. Please help me out 🙂
