[Galaxy Grand Duos i9082 Q&A, Help & Troubleshootin] #Prototype:
Yes!! K2wl has already said tht he won't be adding any new features to cosmicCM! So in the long run and pretty much now too AOGP has more features than CosmicCM!

And its not always about how many features a rom has;its about how many features u use! :)

rooting my samsung i9082 - please help

Hi,

I am new to xdadevelopers. I have been trying to root my samsung galaxy grand duos i9082 so that I will be able to install the below rom:

http://xdaforums.com/showthread.php?t=2627818

I managed to install the CWM by following the steps in the below link:

http://www.ibtimes.co.uk/galaxy-grand-duos-i9082-root-android422-clockworkmod-499739

I am now stuck with installing the supersu. When trying to get to recovery mode I get the droid laid down with the error triangle and after a while it actually goes into the recovery mode. I try to install the supersu and will get the "e: verification failed" errors. It then shows that it installed successfully and the device reboots, but when installing root checker app to verify whether the device has been rooted, I still get the message that it is not installed.

Can someone please help me as I am stuck and don't know what to do next.

Thanks,

Matthew

You have not installed cwm recovery properly. 1st -download cwm or any recovery like twrp, philz and odin 3.07 or above.

2nd -download super su flashable zip.

3rd-open odin and don't check auto reboot and install cwm and wait till pass is shown in odin, then remove the battery and switch on by pressing power off and home and volume up button and instal supersu via recovery.

Hit thanks if i helped you

I can't get to download mode anymore since i have cwm recovery installed (not correctly installed). I try to re-install cwm while phone is still on and I get this error on odin:

please help since this is my first time.

Thanks,

There are so many guide and tutorial for flashing cwm this is Q/A thread for rom so plz don't post off topic ques but anyway i m telling u how to flash cwm.

firstly Download mode and recovery mode are different, for download mode you have to press volume down + home + power and for recovery you have to hold volume up instead of down.

You have to install samsung kies in your your pc to detect your device in odin.

Now open odin and go to download mode in your phone then plug your phone via usb ,if odin did not detect then install usb drivers too. After u plug your phone via usb and odin detects then uncheck auto reboot option and select PDA and select recovery u have downloaded, at first it will check it then press start and wait until pass is shown, then switch off the phn by taking off battery and reinsert it and hold power+home+volume up till Samsung logo come up then u will enter in cwm recovery then install super su

Plz use your spare time to press thanks button:p:p

select width -1080

slect DPI - 480

- Hold capacitive menu button

2. How to use multi window?

- Drag 2 apps from sidebar to home screen

3. How to hide/show sidebar?

- Long press back key button for 2-3 seconds

4. Why Led indicator (sms/call notifications at top) is not working for incoming missed-call or missed-sms?

- Install Light Manager (included in rom) and change LED color to "Green" for CALLS and SMS and also run Test to check color. LEDs of phone can show only two colors, Green and Red, so do not change to any other color, else LED LIGHTS will not work.

5. Why do I always experience Unfortunately, SystemUI has stopped?

- If you have facebook messenger installed, drag down chat head(s) to close it then reopen messenger application shortcut to restore System UI back to normal. (Do this if you encounter similar issue with other messenger applications like Viber, Skype, etc...)

- Freezing Facebook messenger will also solve this issue.

- Just found out that even the original HDC Galaxy Note 3 clone which is the source of this ROM also experience this issue.

Hey bro, Installed last night and using it since, with out sleep :D;)

1st thing I notice is resolution problem as shown in ss below, even its the problem some apps like whatsapp, After using kk custom rom, this ROM feels little laggy, and battery obviously not impressive, anyway core is a jellybean system so can't expect more in terms of performances

but if this ROM was available b4 kk update its the best note3 mimic ROM so far, camera quality is superb, but MP is inverse, front is having 13mp and rare with 6mp, i think it should be vice versa,

Aircommmand only pops up, which make me so happy but sad that only search options works on it :(

multiwindow is Woking with litl lag but it works :thumbup:, any idea of including other apps in side bar for multiwindow, tried all muilti window manager apps on play store.

Smart stay works sometimes or may be I don't know how to make use of it :D

Dolby and music player is working like charm

Air gesture works well on launcher and gallery

Really ROM looks premium,

I would suggest any who want to have a best note3 ROM its would be this
