[Galaxy Grand Duos i9082 Q&A, Help & Troubleshootin] AndroSteel:
I think the developer mentioned it is not a bug, indeed it's CM behaviour (it uses proximity sensor to determine whether to turn the screen ON/OFF so you cannot respond to a call accidentally when you got your phone in the pocket)

[Galaxy Grand Duos i9082 Q&A, Help & Troubleshootin] AndroSteel:
The procedure to activate root access mentioned above is accurate, and if it doesn't work for you, it means the problem is your not the ROM, so please make sure you don't have "dirty-flashed" any deltas and flash the full ROM instead. As for the recovery, none of us is a wizard, so provide more information about the problem:

-What recovery is flashed in your phone?

-How are you trying to access the recovery mode?

-If its not the recovery in the OP, are you sure its intended for this specific device?

-If its some kind of recoveries intended to be "ported", make sure you have the correct version with the same screen resolution.

good rom but a question.......

Amazing!!!!! am going to flash it, but before this, do we really need to use odin for flashing via recovery? cant i just save the file my grand and press home button volume down and power button, then i choose to install the zip from the phone itself???? i wanna verify. pls reply!!! pawitp!! :)
[Galaxy Grand Duos i9082 Q&A, Help & Troubleshootin] AndroSteel:
The ROM is not ODIN-flashable, you must flash it with a custom recovery with SELinux support (Check the OP)

Edit:

But the recovery itself (recovery.img) must be flashed via ODIN

the kernel link of github.

the kernel link given above takes us to git hub. when should we install it?? should we use cwm for that? pls reply someone out there?
[Galaxy Grand Duos i9082 Q&A, Help & Troubleshootin] :
No need to flash a kernel the ROM comes with a kernel

if you want more customizeable one use frost

Flash it via recovery
[Galaxy Grand Duos i9082 Q&A, Help & Troubleshootin] jaimin@j.v:
then why did pawitp give its download link? what is special in that rom? :confused:
[Galaxy Grand Duos i9082 Q&A, Help & Troubleshootin] :
That's the source code of the kernel

android is open source so devs provide sources of kernel and android source code

Sometimes they provide Patches to fix something

Incoming call/message popup is not displaying

Hi pawitp,

Thanks for your interest in developing Custom Rom for Grand duos. I earlier used Samsung stock ROM and hated the phone. But now it is something like a new phone and enjoying the performance and UI.

Unfortunately, I am getting issue with notification popup. Please find the complete details below.

What is your--

Phone model (I9082 or I9082L): i9082

Radio (baseband): I9082DDUBNB1

CM version: 12.1-20150704

CM Download url: http: // d-h.st / nius

Gapps version: gapps-lpmr1-20150503-signed.zip

Did you--

wipe: wipe data/factory reset, wipe cache partition, dalwik cache

restore with titanium backup: no. Used Helium for call logs and messages backup. But old messages are not showin in Messaging app.

reboot after having the issue: Yes

Are you using--

a task killer: no

a non-stock kernel: no

CMSettings/Performance settings (other than stock): NO

Dual SIM: Yes

other modifications: Installed SuperSU 2.46

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

1. Incoming call popup/large screen is not showing. However, I can see the popup when manually scrolling down the status bar, but this is also not staying more than 1-2 seconds and always blinking. Device is hanging when this is happening. I am unable to use any buttons or unable to launch apps while getting the call.

2. Incoming messages(message notificaitons) are not showing as popup. I am opening status bar to see the messages when I hear the message sound.

Please check this issue.

Thanks,

Sandeep.

1. Simply tried to flash on the current build.

2. Wipe cache and delvik cache and tried to flash it.

3. Format system, cache, data, data and data (internal storage) and tried to flash it but didn't get luck.

Is there anything that I have missed.

Bye the way you have done a great job pawitp. Only because of you our grands are alive.:good:

---------- Post added at 08:54 AM ---------- Previous post was at 08:22 AM ----------

Did you make any modification of system files. Did you get root. If you installed any app which need root access then most of the time the system files get modified automatically. In that case you can't use OTA update. You have to download the whole package (which I do every time)

---------- Post added at 09:10 AM ---------- Previous post was at 08:54 AM ----------

(It's good to see that you are using TWRP. I could not make it stable in my grand)

May be you have to install another launcher. Try google now launcher. I am not sure about it. :D

---------- Post added at 09:26 AM ---------- Previous post was at 09:16 AM ----------

Don't jump into kernel flashing business. It's hardly needed. To flash a custom ROM you just need to have a custom recovery like TWRP or CWM Recovery and root access. That's all.

---------- Post added at 09:34 AM ---------- Previous post was at 09:26 AM ----------

Flash the TWRP/CWM Recovery through Odin. Instead of rebooting, go the recovery mode and make sure that the recovery mode is working.

Wipe cache and delvik cache to avoid boot-loop.

Boot into system to make sure that everything is working fine.

Copy SuperSU.zip file into your external memory card and reboot to recovery.

Flash the SuperSU.zip through TWRP/CWM.

Wipe cache and delvik cache to avoid boot-loop.

You are done.

Try flashing another build. I suggest to flash this (cm-12.1-20150627-UNOFFICIAL-i9082.zip) build which is working fine for me. I think the build has got some problem. You will get the build in main page's download section. Happy flashing.

The log you have posted is an error from "com.mxtech.logcollector" and has nothing to do with Dialer.

- If you did not try wiping again and not restore data, try that first. Crashes are often caused by restoring incompatible data (no matter what app you use).

- If it is still crashing, post the full logcat.

Hello,

As I am using the latest one uploaded on 08.04.2015 I would like to highlight a couple of key issues:

1) Settings> Simcards: After Restarting the option "Preferred SIM for Mobile Data" always resets to the service provider inserted in SIM 1 even after changing the option to SIM 2 several times. This happens on every restart of the phone.

2) Settings> Mobile Networks: SIM CARD settings: Access point names show the same APNs for Sim 1 and Sim 2.

3) Settings> Sounds: Link Ringtone and Notification Option not working: In either ways ON or OFF: by default it is functions as ON and cannot be set independantly.

Setup Wizard crash solution

Hi,

To resolve the Setup Wizard crash error, please try below mentioned steps

1. Flash the 12.0 ROM any build ( i used cm-12-20150224-UNOFFICIAL-i9082.zip)

2. Flashed gapps ( for me it was gapps-lp-20141220-signed.zip)

3. Setup the Phone - (google/cm account etc)

4. Flash 12.1 (cm-12.1-20150410-UNOFFICIAL-i9082.zip) -

Do not wipe anystuff

5. Flash gapps (i used - gapps-lpmr1-20150503-signed.zip)

and you are ready to go.

I suppose that u can use any files in point 1 and 2, I have used whatever was available for me without downloading new stuff :)
