[UNOFFICIAL][ROM][4.2.2] CyanogenMod 10.1 for Samsung ExpressATT (SGH-I437) - Samsung Galaxy Express SGH-I437 ROMs, Kernels, Rec

This ROM is for the AT&T SGH-I437 ONLY! It is NOT for the GT-I8730! Just because Samsung named them both "Express" does not mean they have identicle internal hardware!
CyanogenMod is a free, community built, aftermarket firmware distribution of Android 4.2.2 (Jelly Bean), which is designed to increase performance and reliability over stock Android for your device.

* I am not responsible for bricked devices, dead SD cards,

* 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. Source code for the Samsung Express builds can be found on my github, www.github.com/jt1134. And if you would like to contribute to CyanogenMod, please visit out Gerrit Code Review. You can also view the Changelog for a full list of changes & features.
What are Unofficial builds? Builds of the latest CyanogenMod source from github. This version is not officialy supported. If you find bugs/issues you can/must discuss here (do not submit bug reports on CyanogenMod issue tracker).

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.
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.

Phone model:
Radio (baseband):

Wtf. Thought I removed the bootloader check. Will post a fix shortly. Meanwhile you may simply remove the check from the updater script and flash the current zip.

Awesome, thanks. Glad the radio functions work, really didn't feel like having to mess with it any more. Already burned months of my life away fixing radio issues on other devices.

funny thing I've noticed is the difference between RAM with cyanogemod that says I have 743mb and 811 mb stock?
ok any other important information that you require?

Reserved memory allocation is handled differently in the kernel base I'm working on, and is still a WiP. Don't expect those numbers to match up. They only represent the total memory available to the system (total memory - kernel memory).

---

Also,
fixed camcorder (on both cameras).
Update soon

Nice work this is getting awesome fast, you should incorporate Trickstermod kernel settings, they do some amazing work with kernel controllers. :good:

---

Will you be developing for I8730 too?
It will be more than appreciated

He has already responded to this, the answer is no because these are two different phones wih the same name. The gpus are different among other things. The dev needs the actual phone in his hands to do a port.

I have a problem when you restart the phone with 10.1 cm boot image that says "Samsung Galaxy Express" is distorted and I can solve that?
