  58. Will your process unlock the other vendors Network? If yes how, i have followed all the steps which are mentioned in your post.

    ReplyDelete
    Replies
    1. The unlock procedure for other network is quite complicated, the modem have it's own firmware that too in it's own instruction set with encrypted form.
      We can unlock it, but I don't want to perform such complicated process on my limited time, it could be dangerous for modem itself.
      it will completely out of your mind because it require lots of instruction set and Reverse engineering knowledge, if you have one I could only hint you.
      These are following:
      1. Extract original modem.img
      2. Unpack it
      3. You'll find parts of binary inside it, concat them. (it's up to you, how you do it)
      4. Open it in it's Qualcomm specific decompile kit
      5. Patch network detection logic that resist other vendors
      6. Repack it
      7. Again make its parts as it was before
      8. Make modem.img file from it
      9. Flash it.

      Now it's up to you how you do it.
