Flashed the new build after wiping cache/dalvik (something I always do at this point) ... audio issues fixed. No crackling audio at all (but I've only had it on for a short while). Looking good so far, thanks very much jocala!

Antutu shows benchmark dropped from 3330 to 3239 between 0412 to 0421

Other diff was sdswap applied. Wonder if that can cause a drop in perf.

It's possible that the swapsd had an effect on your score depending on the difference between the read-write speeds of the internal (originally) SD card versus the one in the slot. The other factors that could change it include the number of background apps and other processes that could use resources. Regardless, the difference is a meager 2.7% which could just be statistical variance.

Jocala, any chance the camera of this Samsung tab is compatible with the exhibit ii? Both are 3.2mp Samsung cameras with flash and it's working somewhat on ics

See the thing is that not only does it have to have the 3.0mp camera but it has to have the same vga front facing camera as well as the same snapdragon processor. Plus it needs a camera working version of ics. If we find this ( unlikley ) we can use those drivers

Weird bug last night - went from playing my game to the blue Cyanogen Mod 9 animation that happens when my phone starts up - for about ten seconds, then back to my home screen. It wasn't a reboot though because my place in my apps was still held and it didn't re-scan the SD Card. Hasn't happened again, just freaked me out!

boot loop

I just flashed to the 4/21 build, wiping davlik and cache beforehand, and for the first time with this rom I've gotten a boot-loop, it just sits on the skateboarding android animation and vibrates haptically every half minute... any ideas on cause? I was running the 4/14 release before

Upgrade Procedure

First; Thanks to everyone working this. I have been running this on my spare (Bad IMEI) Exhibit II for about a month, and am ready to transition to my everyday Exhibit II. I would like to get some feedback on the procedure that I use when flashing. I have a feeling that it could be a lot more efficient.

1. Perform a full TB Pro batch backup of any new applications.
2. Reboot into CWM recovery.
3. Perform a full Nandroid backup in CWM.
4. Perform a full RomWipe. (it is never clear when a RomWipe is required!)
5. Restore CM9 from zip file.
6. Restore Gapps from zip file.
7. Reboot
8. Login to Google, but decline sync to Playstore.
9. Install TB Pro from Playstore.
10. Batch restore all user applications and data with TB Pro.
11. Manually restore Home screen and folders.

All of this can take a fair amount of time.

a. When is a Romwipe required?
b. Is there anyway to create a zip file of all of my user applications, and flash them in CWM?
c. Is there anyway to save and restore the home screens and folder structure?

Thanks,

Mike

Almost impossible to say. If you're interested in diagnostics, you could connect to your PC and do an adb logcat and maybe see what's what.

For a fix, I'd boot into recovery and do a cache/dalvik wipe. Reboot and see if that fixes things. If not, boot into recovery and do a romwipe followed by a re-install.

I romwipe when:

1. Installing over a non-cm9 rom.
2.I'm testing a new build and want a clean platform.
3. Having trouble a cache/dalvik wipe doesn't fix.

I keep a TB backup of apps. I also keep my apps in a directory, easily installable with:
Code:
cp /emmc/apps/*  /data/app
I keep a clean state cwm backup of each rom I work with (rooted stock, peach and cm9), replacing when required.

Thanks Jocala. Is a Romwipe required when the kernal changes as well? I noticed that the 4/21 build had the kernal updated, and assumed that a full Romwipe was required.

    This is a port of CyanogenMod 9 (Android 4.0.x) for the Samsung Exhibit II 4G. It is very much a work-in-progress. There are no guarantees whatsoever that it will work to your requirements or that it will progress beyond its current state. Major kudos to Arco68 for his help in getting this going; you would not have this ROM except for him.

    Here is a video by dennis96411, showing CM9 on the Exhibit II

    What seems to work
    Phone
    Wifi
    SMS/MMS
    GPS
    Bluetooth audio
    Amazon Market
    HW accelerated display
    Headphone detection
    Microphone detection
    T-Mobile Wifi-calling (works for most)
    init.d support
    CIFS networking
    Camera (Stock Camera only, 3rd-Party apps mostly don't work)
    Haptic keyboard feedback
    Market/Play
    Gmail
    Browser
    Screenshots
    Streaming video

    What does not work (NO ETAs)
    911 Emergency Calls
    Torch app (check thread for alternatives)

    CM9 for the Galaxy Exhibit is NOT vulnerable to USSD dialer exploits.

    Vanishing text
    The content of text buffers sometimes disappear when touched (messages in: gmail,yahoo,fb). Wiping cache has fixed this for some. Long-press of back key and restarting app for others.

    Facebook
    Facebook sync is not included in AOSP. 3rd-party apps are available in the market.

    3g vs 4g
    Cyanogen Mod views UMTS as 3g whereas the stock Exhibit II rom views it as 4g. Even though you see 3g on your status bar, your actual speed should be unchanged from stock.

    Changing band preference
    In dialer, enter Service Mode via
    You should see:
    [1] Automatic
    [2] WCDMA Band Preference
    [3] GSM Band Preference

    To force WCDMA only, tap option 2, on next screen tap option 6 - WCDMA All

    To force GSM only, tap option 3, on next screen tap option 7 - GSM All

    You can use the back button to verify your settings took effect. To exit, tap menu button, quit. This change does not survive a reboot. If you use this frequently, save it as a contact.



    WIFI Problems
    Wifi is working fine for almost everyone using CyanogenMod 9 Galaxy Exhibit build (and also for the Galaxy W). If you are one of the very few having difficulties, a possible fix has been posted that may help: WiFix Manager.

    Installation
    Installation requires a CWM-based recovery. Download/update Galaxy Exhibit Custom CWM Recovery here.

    Updating CyanogenMod 9
    Once you have a stable install you're happy with you can apply future updates w/o any wiping. If for some reason a wipe is required, I'll make that known.

    Download CM9 Beta
    Core2idiot's CM9 Nightlies

    Google Apps
    Google Apps gapps-ics-20120429-signed.zip .... Mirror

    Kernel sources

    Copy the downloaded cm9 beta and gapps zip files to your internal or removable sdcard.

    Back up your data.

    Start Custom Recovery (cwm): Press & hold Vol-Up, then press & hold Power. Shortly after the plain white Samsung logo appears, release both buttons. Recovery should start after the color Samsung/T-Mobile Exhibit logo.

    CWM Keys:
    Home key = enter
    Back key = back
    VolUp/Dwn = highlight choice

    If installing over a non-CM9 ROM you must do a ROMwipe before installing.

    Select "Install zip from sdcard." Choose the cm9 beta zip from sdcard or external sdcard, depending on where you placed it. Highlight the cm9 beta zip file then press Home. Confirm the choice and installation will proceed. You may also install Google Apps (gapps) at this time. Gapps does not include all Google apps. Those not included are available from the market.

    Please DO NOT PM me with support questions! Post them in this thread!

    adios

    I'm moving to a Galaxy S2, so my work on CM9 is going to draw to a close. If you have a build environment running and would be interested in continuing development for the community, please PM me. It's been a fun ride and I'd like to thank everyone for their support.

    Compile CM9

    Portions copied from Motorola Droid X CyanogenMod Wiki

    Thanks to Arco68 for hand-holding and patches. Any mistakes are mine.

    These instructions assume that you will be using an Ubuntu 10.10 Linux system (or a close relation, Debian, Linux Mint,etc). Setting up a Linux partition or creating a Linux VM are beyond the scope of this post.

    First, Install the Android SDK

    Next, install the linux build packages required. I install using apt-get:

    For 32-bit & 64-bit systems
    apt-get install git-core gnupg flex bison gperf libsdl1.2-dev libesd0-dev libwxgtk2.6-dev squashfs-tools build-essential zip curl libncurses5-dev zlib1g-dev sun-java6-jdk pngcrush schedtool

    For 64-bit only systems
    apt-get install g++-multilib lib32z1-dev lib32ncurses5-dev lib32readline5-dev gcc-4.3-multilib g++-4.3-multilib

    NOTE: gcc-4.3-multilib g++-4.3-multilib is no longer available for Ubuntu 11.04 64-bit, but should still build without issue.
    NOTE: On Ubuntu 10.10, and variants, you need to enable the partner repository to install sun-java6-jdk:

    add-apt-repository "deb http://archive.canonical.com/ maverick partner"

    NOTE: sun-java6-jdk <> open-java6-jdk!
    These instructions assume an "android" directory located in your home

    Install repo
    Code:
    mkdir ~/bin
    curl https://dl-ssl.google.com/dl/googlesource/git-repo/repo > ~/bin/repo 
    chmod a+x ~/bin/repo
    Download CM9 source
    Code:
    mkdir ~/android/system
    cd ~/android/system
    repo init -u git://github.com/CyanogenMod/android.git -b ics
    repo sync -j16
    This can take hours. When done, ~/android/system should be at least 11Gb in size.

    Next:
    Code:
    cd ~/android/system/frameworks/base
    git remote add arco git://github.com/arco/android_frameworks_base.git
    git fetch arco
    Download kernel source
    Code:
    mkdir -p ~/android/system/kernel/samsung/ancora_tmo
    cd ~/android/system/kernel/samsung/ancora_tmo
    git init
    git pull https://github.com/arco/samsung-kernel-msm7x30.git
    
    Repeat the pull command occasionally to obtain updates.
    Download ancora_tmo device directory
    Code:
    mkdir -p ~/android/system/device/samsung/ancora_tmo
    cd ~/android/system/device/samsung/ancora_tmo
    git init
    git pull git://github.com/Jocala/device.ancora_tmo.ics.git
    
    Repeat the pull command occasionally to obtain updates.
    Download ancora_tmo vendor directory
    Code:
    mkdir -p ~/android/system/vendor/samsung/ancora_tmo
    cd ~/android/system/vendor/samsung/ancora_tmo
    git init
    git pull git://github.com/Jocala/vendor.ancora_tmo.ics.git
    
    Repeat the pull command occasionally to obtain updates.
    Set up prebuilts:
    Code:
    cd ~/android/system
    ./vendor/cm/get-prebuilts
    Applying cherry-picks
    You'll need to gain at least a rudimentary knowledge of
    using git and github. Teaching this is beyond the scope
    of this howto. Cherry-picks must be re-applied after each
    repo sync.As time goes by they also get merged, so it may be that some
    cherry-picks are no longer required. You can check their status here.

    Attached to this post is a script (reposync.txt) that will do a repo
    sync then apply current cherry-picks. I keep it in my
    android/system directory. Rename and chmod 0755.

    Set up your environment & build

    Code:
    . build/envsetup.sh
    lunch cm_ancora_tmo-userdebug
    brunch ancora_tmo
    Building takes at least an hour. If everything worked, you should have a
    out/target/product/ancora_tmo/cm-9-SOMEDATE-UNOFFICIAL-ancora_tmo.zip file

    ============

    CCACHE

    If you have room on your build system you can speed
    your builds up considerably by using ccache. ccache is a compiler
    cache. It speeds up re-compilation of C/C++ code by caching
    previous compiles and detecting when the same compile is
    being done again.

    Install it with apt-get: sudo apt-get ccache

    Set environment vars for Android use:
    (I put these exports in my .bashrc)
    Code:
    export USE_CCACHE=1
    export NDK_CCACHE=ccache
    Set a cache size of 10G for optimal results:

    Code:
    ccache -M 10G
    Check the status of your cache with the command:
    Code:
    ccache -s 
    
    Returns:
    
    cache directory                 /home/jocala/.ccache
    cache hit                         106673
    cache miss                         18379
    called for link                     3758
    preprocessor error                     5
    not a C/C++ file                    4425
    unsupported compiler option          678
    no input file                       4565
    files in cache                     36758
    cache size                           3.2 Gbytes
    max cache size                      10.0 Gbytes

    This is true. My phone always says 3G, but switches to H when downloading, then goes back to 3G.

    Also, even though he's now ignored, Nightlies aren't forced updates. You can flash over the update whenever YOU want. They're just always supplied on a nightly basis in case there have been any changes to the repos. Since it's CM9 there probably won't be many new changes, but its still offered...

    Sent from my SGH-T679 using xda app-developers app

    It's always hilarious when a newcomer shows up who absolutely knows it all, refuting everything we only think we know about our phones.

    I think the idea of nightlies is great, I never had the resources. I've replaced the OPs download link with a link to Core2Idiot's nightly page.

    On another note, I've decided to keep my Exhibit as a dev device, so I'm going to continue busting my head with 911 for a while at least. I'll post if I have any breakthroughs.
