[Samsung Galaxy Express GT-I8730 ROMs, Kernels, Rec] szezso:
This ROM is for the International GT-I8730 ONLY! It is NOT for the SGH-I437! Just because Samsung named them both "Express" does not mean they have identical internal hardware!

CyanogenMod is a free, community built, aftermarket firmware distribution of Android 4.4.4 (KitKat), which is designed to increase performance and reliability over stock Android for your device.

* I am not responsible for bricked devices, dead SD cards,
* thermonuclear war, or you getting fired because the alarm app failed. Please
* do some research if you have any concerns about features included in this ROM
* before flashing it! YOU are choosing to make these modifications, and if
* you point the finger at me for messing up your device, I will laugh at you.

CyanogenMod is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restore the Google parts. CyanogenMod does still include various hardware-specific code, which is also slowly being open-sourced anyway.

All the source code for CyanogenMod is available in the CyanogenMod Github repo. And if you would like to contribute to CyanogenMod, please visit out Gerrit Code Review.

Reporting Bugs

You are allowed to report bugs only in this thread. Before reporting a bug, please make sure you are running as stock as possible. This means no custom kernel, no custom framework modification, etc. If you are using any of the above modifications, please flash the rom again to get rid of the modifications before reporting.

If you're having issues like these:

-Phone reboots randomly.

-Phone blacks out, and you have to force shut down/remove and put the battery back in for it to turn on again. (This problem doesn't happen when it's plugged in though)

-No Audio AT ALL.

-No calling works, phone also sticks/freezes when you try to make or accept a call, there is a blank screen. When the call does go though, neither you or the other person can hear.

-No video plays either, test with youtube if you're unsure about this one.

-Several apps/features that attempt to play audio crashed and freezes.

Try this (thanks to [MENTION=6002443]toxious651[/MENTION]):

1. Factory reset current rom and clean cache.

2. Download and install this entire firmware using ODIN (make sure you use this specific firmware):

http://samsung-updates.com/details/16541/Galaxy_Express/GT-I8730/KPN/I8730XWAMK1.html

Note: I recommend you use the terafile.co link, to download, scroll to the bottom under "Free" and click a link that says "Regular", close the popup, enter the captcha when the countdown is done and click "Create Download Link".

3. Check if audio, calling, and playing videos work after installing that firmware. If they do, then continue to do the remaining steps.

4. DO NOT DOWNLOAD OR FLASH THE BASEBAND IN THE OP. The firmware I gave in step 2 covers that.This is important, do not use that baseband as it is probably the source of your problem.

4. Root the phone

5. Install clockworkmod recovery

6. Factory reset and clean cache

7. Install CM11 Zip

REPORT BUGS IN THIS THREAD ONLY

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)

Remember to provide as much info as possible. The more info you provide, the more likely that the bug will be solved. The following is a useful format to follow.

What is your--
Phone model:
Radio (baseband):
