I would help you out if I was able to get some more days off of work…lol

    Well, back to stock, CM9 Nightly is good but kinda laggy, imma wait for the “stable” versión. Btw its a nice work, the only one is the FM Radio missing. What about a CM7? Not available?

  11. nzo_ says

    Great mod. Works perfectly! Much better than the original gingerbread. I have even Chrome now (didn’t let me install it before).

  18. ruizren says

    i have rooted my phone and installed the clockwork mod recovery, but when i will reboot to recovery it hangs on the LG screen. i really don’t understand it. Can anyone help me with this. plsss

    • Borisb131286 says

      Just remove your battery as long as it doesn’t swich into a CWM Recovery Mod.And try before you do install ICS CM 9 oficiall that you get a latest V10j update frimware over the OTA on your Android or over your LG PC Suite on your PC or MAC Computer machine what ever of thouse 3 you have.And see what is going on after that.

  19. Boris Blagojevic says

    There is more things missed like PC Suite and Mass Storrage, Update Baseband from V10i to V10j and the latest.and if would be nice and noble from Cyanogen Mod Developers that they give an option flashing Stock ROM OS back on this model I have seen that there are new update for the Stock ROM for this model the size of 27 MB I have heard the rumors that update is a LG Stock Android 4.0.4 so after Orthodox Easter I will flash this my model LG E400 machine back to the Stock ROM so on that way I can findout is that update the size of 27 MB really is a LG Stock ROM Android 4.0.4 ICS and only when Cyanogen Mod release a Stable version of CM10 Jelly Bean Android 4.1.1 I will maybe but just maybe again for the second time root and flash it back to the CM ROM OS.Google’s latest mobile operating system, Android 4.1 with the code name Jelly Bean has been introduced at the Google I/O and running for the first time on Google’s first Android Tablet Nexus 7 and Galaxy Nexus smartphone, this update provides a better user experience since it claimed to be the fastest and smoothest OS. With these offered improvements, as expected attract the curiosity a lot of people to immediately run this update on their devices, you must be wondering whether your device compatible with this update or not.

    There’s no official announcement about the minimum hardware requirements for running Jelly Bean update, but if your current device has been capable to run the ICS update properly, then it’s likely that your device is also compatible with Android 4.1, although it isn’t officially from your device manufacturer. Some low-end smartphone such as the Xperia X8 which only equipped with a 600 MHz Single Core processor and 168 MB of RAM are able to run CM10 custom ROM (based on Android 4.1), so if your device has better specs than that, you have a greater chance to get this update, additionally it depends on the existence of a developers who would develop the CyanogenMod 10 ROM for your smartphone or tablet devices.This is what I have findout about CM10 Jelly Bean ROM OS for this and any android model whether is a smartphone or Tablet PC.

    • Purcea Codrut says

      i had the same problem.
      Enter in recovery mod then click on advance then click on “emty calvik cache” or smth like that

  25. says

    I installed CM9 on my LG L3. It worked so fine. Fast and smooth UI. Until I noticed some bugs or whatever you might call it.

    1. There’s no PLUS button in which I need to select contacts on “message”.

    The function in which you need to send group message, it’s not there. :((

    2. There’s no option to delete multiple contacts in “contacts”.

    3. Whenever I want to end the call, the phone sleeps. I need to press the unlock/power button to keep it awake.

    4. There’s no GOOGLE PLAY (at first!) You need to install or flash GAPPS. (please ninja romeo, include this on your tut.. thanks)

    5. After a week and my phone was not much loaded with apps. I just installed INSTAGRAM, FB MESSENGER, GROUPY (for group message purpose), TWEETCASTER and 2 games, BASKETBALL MANIA and PANDA RUN. There’s like a135 mb free storage space and 800 + mb internal storage BUT WHY DOES MY phone keeps on FREEZING? :( Please give me answer to this. I am loving CM9 but with this, it breaks my heart guys =(((

    6. Every time I need to boot or whenever I remove the battery coz it freezes a lot, I need to press Volume Down, the home button and the power button at the same time. Can we just press the power button and not get the battery icon blinking? :(((((( BOOOOOOOHOOOO!

    On the other hand what I like about this ICS CM9,
    1. voice search is accurate
    2. smooth UI
    3. The phone storage is pretty much accessible.
    4. Camera works so fine!

  44. hfdh says

    Data doesn’t work. :(

    APN settings don’t save: I enter APN info, click save, and APN list still empty.

    Programs like APN database etc. say like “unrecognized sim card”.
    I did factory reset but it didn’t help.

    I still can make phone calls and use wifi. Data was working before this upgrade!

    any ideas? Thanks!

    • moralesnery says

      Every time you change the ROM, your APN settings get lost. You can enter them manually, just ask your carrier or search in Google. Is not that hard.

      • hfdh says

        You didn’t get it.
        I enter APN settings, click save, but phone doesn’t save these settings. APN list is still empty, and phone unable to use DATA.

        • moralesnery says

          I get it now, you can try going into recovery and doing full wipe, erasing caches and then reinstalling the ROM. If that doesn´t work, maybe you should try another ROM.

  45. Melanie says
