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.
Here is a video by dennis96411, showing CM9 on the Exhibit II
What seems to work
HW accelerated display
Haptic keyboard feedback
What does not work (NO ETAs)
Bluetooth calling features
With CM9, your removable sdcard is mounted under "/mnt/emmc" and symlinked to "/emmc"
Facebook sync is not included in CM9. 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.
Installation requires a CWM-based recovery. Download/update Exhibit II 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 these files
CM9 Beta: cm9.beta.042112.zip
Google Apps: gapps-ics-20120317-signed.zip
Copy the downloaded cm9 beta and gapps zip files to your internal or removable sdcard.
Back up your data. This installation will format your data partition if you are not already running cm9.
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.
Home key = enter
Back key = back
VolUp/Dwn = highlight choice
If installing over a non-CM9 ROM you must do a ROMwipe before installing. If you are installing over a previous version of the CM9 Beta I suggest that you wipe cache and dalvik.
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.
