[ROM][UNOFFICIAL] CM 11.0 for Galaxy Grand Duos (I9082/I9082L) (Update 20140709) 2SIM
CyanogenMod is a free, community built, aftermarket firmware distribution of Android 4.4 (KitKat), which is designed to increase performance and reliability over stock Android for your device.
* Your warranty is now void.
* 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
. You can also view the Changelog
for a full list of changes & features.
Device-specific source code for the Samsung Galaxy Grand Duos are available from https://github.com/pawitp/android_device_samsung_i9082

How do I enable/disable Dual SIM?
starting from 20140505, Dual SIM support is enabled by default. If you only use 1 SIM and wants to disable Dual SIM support, you can use the following instruction:
setprop persist.radio.multisim.config dsds
What are incremental/delta updates?
setprop persist.radio.multisim.config none
Delta updates allow updating from one version to another downloading only the difference rather than the full ROM, for those on limited bandwidth. They are named like "cm-11-20131215
_delta-UNOFFICIAL-i9082.zip" which means that it can be used to update from 20131215 to 20131216 (simply flash it in recovery like any other update). Delta updates will not work if you have installed custom kernels or other system modifications, including editing build.prop
. In those cases, downloading the full update is recommended.
Can you include Feature X into your ROM?
No. This ROM will have CyanogenMod's feature set.
Can you include S-Note/S-Planner/MultiWindow/Insert Samsung App Here?
No. This is an AOSP ROM and cannot have TouchWiz applications.
Can you include call recording?
No. CyanogenMod does not include call recording to avoid potential legal issues.
Can you add Feature X to the stock ROM?
No. I don't work on stock ROMs.
What kernel does this ROM use?
A slightly modified version of the stock kernel, the source code is linked above.
I've heard that Broadcom doesn't release source, how can you make this ROM?
Contrary to the popular belief, userspace driver source code is not always required to make an AOSP-based ROM as long as the proprietary binaries shipped with the device does not modify the API too heavily (or is from a very different version of Android). Instead of modifying the source code of the drivers, the Android source code was adapted to be able to use the proprietary binaries.
Can I use your ROM as a base?
Most of Android/CyanogenMod is licensed under the Apache License with other small parts licensed under other open-source licenses. Which means that you may modify and redistribute without asking for permission as long as the proper credits is given and it is not misappropriated as being the official CyanogenMod. (In other words, you must say that it is based on pawitp's unofficial CyanogenMod, but is not related to CyanogenMod in any other way.)
Will you make this official CM?
Due to the amount of work and commitment involved, I am not planning to make an official CM port.
Can contacts be saved to phone/SIM?
No. It is not supported in AOSP-based ROMs.
Can I send files over Wi-Fi Direct?
Yes, but you must use third-party applications. The implementation provided on Samsung ROMs is not an open standard. AOSP/CM does not provide a native way to send files over Wi-Fi Direct.
Can I mirror your ROM?
You're free to, but I will not list it in this post.
Is overclock (OC) available?
Since 20140101 build, 1.3 GHz OC is available in Settings -> Performance -> Processor (enable developer mode
first). Higher frequencies are not enabled since benchmark
does not show additional benefit.
Will feature X from a previous version of CM be implemented?
I don't know, probably will be, eventually. I don't really involve myself in the feature-set side of CM.
Will you OTA support?
No. CM Updater is present on the device, but it only works for official devices. I'm not interested in adding an alternative update mechanism. If you want to know when a new ROM is released, follow the rss feed at http://goo.im/rss&path=/devs/pawitp/i9082_cm11.0
I cannot add APNs
Make sure you set the correct MCC/MNC code, the APN will not appear otherwise. Also make sure to use menu -> save (back button means discard).
Recovery asked me "ROM may flash stock recovery on boot. Fix?"
Short answer: "yes" or "no" doesn't matter
Long answer: Newer versions of CM starts including recovery with the ROM. However, this does not get flashed unless the "Update CM recovery" option in system settings gets ticked. If you say "no", the current recovery will not get overwritten (unless you enabled the "Update CM recovery" option), but it will continue prompting you every time. If you say "yes", CM's recovery flashing mechanism will be disabled until a newer version of the ROM is flashed.
I get "Throttle Limited Exceeded" or "We currently accept only US numbers" when an unknown number calls
It's a bug of all CM11 ROMs with the reverse lookup code in the dialer. You can work around it by
1) Disable dual SIM
2) Go to dialer settings and disable "reverse lookup"
3) Re-enable dual SIM
Does this custom kernel work? Does this app work on this ROM?
Please ask the in Q&A thread
maintained by chotu22. If you're experiencing any problems while running a custom kernel or other system modifications, please remove those modifications and test again before filing a bug report.
You are allowed to report bugs only in this thread.
- 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)
- If the problem disappears after running "setenforce 0" from a root shell, grab /data/misc/audit/audit.log
Remember to provide as much info as possible. The more info you provide, the more likely that the bug will be solved. Please also do not report known issues. The following is a useful format to follow.
What is your--
Phone model (I9082 or I9082L):
CM Download url:
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):
Provide any additional information (observations/frequency of problem/last version it worked on/etc) as needed:
- The CyanogenMod team for providing a great ROM. Without all the compatibility work which went into it, this ROM would've been much harder to make
- My real-life friend for letting me borrow his phone to work on this
- RampantRhino for donating a phone to help me continue with this project
Please do not use email, PM or use social network to ask for support (use the thread), ask for help on another device (I can't help without access to the device) or recommendation on the "best" device/ROM (I only know about what I use).
