  8. I hv run .exe for ec315-5 and now it doesn’t get connected with PC correctly!!!
    As Google chrome opens first page, it demands a code,and after only 2-3seconds it is disconnected.
    .exe firmware failed to recover user info.
    What to do now?

  9. I did every thing you said in the tutorial to find the spc code.
    The CDMA tool shows the code to be 000000 but when i enter it,it says that the code is wrong what do i do?
    Where can I get the meid?

    • u need ur device in diag mode. mine comes up on 2 ports, one is modem option (port 10) and the other is the diag port (port 11 for me) your ports may be different.

  10. i am getting all zeros on the ram setting and it will not scan on the cefs setting. esn is 5f5f980c and 5F5F9239. spc has me locked out. cannot find the meid anywhere.

  11. By this method every time it is giving 000000 as SPC Code. Which is not correct on cdma workshop. I have reliance ec159 huawei.

  12. Please any info about how to go about unlocking huawei ec226 cdma modem….Followed the instructions posted above but not working.

  13. I used EC315_Update_11. firmware to update.
    It has detected the port and now asking for password. Is it the SPC code thru DFS tool? I am not able to get it using DFS.

    MEID A0000043694FFE
    Please provide me the SPC code or the password for the update.
    Is there a tool to get the code?
