Cyanogenmod 9 (CM9) Nightly ROM for Galaxy S — Installation Guide

Advertisement

Cyanogenmod 9 (CM9), based on Ice Cream Sandwich Android 4.0 is perhaps the best custom ROM you can find for any Android device. The CyanogenMod team has recently started adding nightly ROM support for CM9 on various devices. Nightlies are auto compiled builds of the ROM that change every night, incorporating the latest changes made by the developers every day. The Galaxy S i9000 also recently got official nightly support for CM9, after the release of the Android 4.0.4 sources by Google, which brought along performance and stability improvements.

Now, keep in mind that the nightly builds are not officially supported as they are automatically generated builds, but they do help in getting you the latest updates in the ROM at a regular basis. The ROM has a few bugs and issues, a full list of which you can find under ROM Info below.

Read on to find out how you can install the CM9 nightly ROM on your Galaxy S i9000.

  • Jussi

    Hi. Can I just follow the steps from step 4 onwards if I have xxjvu installed and have rooted the phone?

  • H Saeed

    Hey can I install CM9 RC mode (
    cm-9-20120726-NIGHTLY-galaxysmtd.zip ) using the above method?

    • H Saeed

      I meant
      cm-9.0.0-RC2-galaxysmtd.zip

  • OC

    Wifi slow down appears to be due to the CPU management and cutting it down to 100mhz when the phone inactive/sleep – Settings – CyanogenMod Settings – Performance – CPU Settings – Up Min and may fix it at cost of lower battery – 200Mhz and getting 400KB/s or so but it does fluctuate quite a bit

  • Aman

    thank you for excellent guide and steps ! really appreciate.

    Aman.

  • mmmboulos

    i followed all the steps and made sure that the phone was properly rooted, however after installing cm9 (
    cm-9-20120625-NIGHTLY-galaxysmtd.zip ) the phone loops on the boot screen. It just keeps on shutting down and restarting all the time, never gets past the Galaxy S cyanogenmod screen.
    Help?

    • mmmboulos
