• Grab a logcat right after the problem has occurred. (Please include at least a few pages of the log, not just the last few lines, unless you know what you're doing.)
• If it is a random reboot, grab /proc/last_kmsg. (Do not bother getting a logcat unless you can get it just before the reboot. A logcat after a reboot is useless)

What is your--
Phone model:
Radio (baseband):
CM version:
CM Download url:
Gapps version:

Did you--
wipe:
 restore with titanium backup:
reboot after having the issue:

Are you using--
a task killer:
a non-stock kernel:
CMSettings/Performance settings (other than stock):
other modifications:

Provide any additional information (observations/frequency of problem/last version it worked on/etc) as needed:

• You never, ever have to wait for a nightly
• You can add or remove as-yet uncommitted features with ease.
• You learn how Android works under the hood
• You learn how to use Linux
• You'll learn how to use git
• You may, even accidentally, pick up a little C, Java, C++, and learn about the build system.
• You can personalize Android-- make your own tweaks, replace kernels, modules, graphics, add or remove projects, overclock, underclock etc. In other words, you have control over every aspect of your device's functionality. Your build is custom to you.
• You can audit the code for potential security issues such as back doors or trojans (as opposed to just trusting a random person who posts a build). Since CM10 source is open, you can examine every commit, and there are many eyes looking at the code. (does not apply to proprietary blobs, but these are pulled from your device, so you have and are using them already)
• You can contribute features/fixes back upstream
• You can start ports to other as-yet-unsupported devices (start by copying folders from similar devices to devices/manufacturer/model)
• You come to really understand that Android phones and tablets are full-fledged general-purpose computers just like laptops and desktops.
• AAAAND....you get huge bragging rights

• It's fun.

How to Install Cyanogenmod 9 on Galaxy S3 i9300

1. You need clockworkmod (cwm) recovery to be able to install/flash the Cyanogenmod 9 on Galaxy S3. To get that, Install CF-Root, which gets you both root and (cwm) clockworkmod recovery at one shot — easy and simple. Once you have got CF-Root from there, jump to next step.
2. Download the Cyanogenmod 9 from official development page: Link. (This file will be flashed in step 8 below.)
3. Download the Google Apps package. This will install apps like Market, Gmail, etc. which are not present in the ROM by default. (This file will be flashed in step 9 below.)
   Download Link  |  Filename: gapps-ics-20120317-signed.zip
4. Connect phone to PC and transfer the two zip files you downloaded in step 2 and 3 to your Galaxy S3, on the internal sdcard that shows up on PC upon connecting.
5. Disconnect the phone from PC. And power off the phone, wait till it vibrates and the two capacitive lights (Menu and Back keys) go off, to confirm complete power off.
6. Now, enter the awesome thing that we call clockworkmod (cwm) recovery. For this, press and hold these 3 buttons together: Volume Up + Home + Power until you see Samsung logo on screen, upon which you can release them all. You’ll enter recovery mode soon enough. (Use volume keys to browse between options in recovery while power key to select to select an option.)
7. [Optional] It’s recommended you create a backup from the clockworkmod recovery your phone is in right now, using the option Backup and Restore » select backup from internal sdcard. You can restore this backup to get everything to normal in case something turns out bad. You just need cwm recovery for this, which you always get from the link above, in step 1.
8. Wipe stuff now to prepare for installation of CM9 on Galaxy S3:
   1. Do Wipe Data/Factory Reset — select the option and then select yes on next screen to confirm it.
   2. Do Wipe Cache Partition – select the option and then select yes on next screen to confirm it.
   3. Go to advanced and do Wipe Dalvik Cache — select the option and then select yes on next screen to confirm it.
9. Flash the Cyanogenmod 9 on Galaxy S3. Now, form the main menu in recovery, select the optioninstall zip from sdcard, then select choose zip from internal sdcard, and then browse to folder location where you transferred the 2 files in step 4 above, then select the CM9 rom file (which you downloaded in step 2 above). Select Yes – Install _____.zip on next screen to start flashing it. Flashing of CM9 rom will be started.
10. Now, you need to flash the Google Apps too. So, after step 9 is finished and you are back to recovery, go back to the recovery’s main menu. Select the option install zip from sdcard, then selectchoose zip from internal sdcard, and then browse to folder location where you transferred the 2 files in step 4 above, then select the Gapps file (which you downloaded in step 3 above) . Select Yes – Install _____.zip on next screen to start flashing it. Once gapps have been flashed, go back to recovery’s main menu.
11. Select reboot system now to reboot the phone and boot up into lovely CM9 rom, void of all Samsung bloatware and its TouchWizUX UI (although some may miss it), based on Android 4.0.4 and taste the pure android experience as Google meant it to be.
