[Samsung Galaxy Exhibit 4G] jocala:
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

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.
