  1. Flashed cm 13 after flashing hydrogen os with VoLTE, When I try to call with my JIO sim there was no connection to the network, like totally blank, hope to see a fix for this on CM 13 as this is the most stable CM rom for One plus two

  2. Hello…
    I succesfully installed this rom…*non root method..
    It works like a charm..
    But battery doesn’t seem better than oos lollipop….Then I rolled back to lollipop then ..my sim cards wont get detected …
    Looking for a possible solution….

  3. Please don’t flash…..
    There is signal drop issue.
    The signal drops ever 5 – 10 min

  4. Hey thanks for this great post !!!!!!

    The ROM works excellent except the network drop issue.
    There is a frequent signal drop for few seconds when you travel and it is a bit annoying experience.
    Is there any alternate modem which I can flash?

    It would be great if you post solution for the network issue.
    Thanks in advance !!!!!!!

    • Ok I will. For now only solution for network drop isuue is to flash oxygenos 3.1 and flash the orignal modem again.

  5. Can we flash this modem on Oxygen OS 3.1.0 to get volte support?
    Or it only does work for h2os 2.5?

      • I Flashed Modem On CM 14.1 After That My Both Sims are not Detected.Then Came Back To Stock (Quallcomm Reset Method) Still My Both Sims are Not detected.
