[Galaxy Grand Duos i9082 Q&A, Help & Troubleshootin] raghavsharmaxda:
//I AM STILL TYPING AND WILL TAKE TIME << SO DONT REPLY :P

i had typed and mistakenly deleted the tab before clicking post :|...i will delete these two lines once i am done with everything//

guys!

something we are all familiar with on galaxy grand forum is spamming!

indeed there are still many users/new users who post WRONG POSTS in WRONG SECTIONS..

still u can find questions which are off-topic/not related to forum/which have been answered several times/which have been asked several times by making new threads etc.

it not only takes up unnecessary space on server, but also lowers the value of GALAXY GRAND DUOS community..

developers getting pissed by day to day ETA's and helpers pissed by posting same and same answer, to several people !

i do know that xda's search option on top right might be not that accurate for some here,

SO

here i am here making an illustrative thread,(after discussing and opinions from many on xda)

WHICH will not only help you to solve ur problems regarding roms, but also day to day frequently asked multiple times answered questions....

its possible that it does not contain everything that u need , but seriously guys, it will at least decrease number of SPAMS on our threads...

all problems will be mostly illustrated below.........

just read it once please before posting in all other forums....

Few Information better read before any Posting!! (most Important..)​

1. AOSP based Rom/ Non touchwiz Rom (cm11/carbon,resurection remix, paranoid android,Pac-man ,Omni,and others)DO NOT support DUAL SIM Functionality..(it Requires Broadcomm Specific Codes which are not released as Open Source)...

you want Dual Sim , be On any touchWiz based Rom(Stock, Gennxt , etc)..

2.

Difference between Touchwiz based Roms and AOSP Based Roms of our Device

1. AOSP Roms DON'T HAVE Dual sim functionality.

2. these are small in size as have only basic android Framework and Do not include bloatwares.

(Roms size~198mbs+)

3. AOSP Roms don’t have TW features, (but have their own**)!

4. they are Highly Customizable and meant for performance.

5. Lower RAM Consumption compared to TouchWiz.
​

1. Touchwiz Roms HAVE dual sim functionality

2. TouchWiz Roms are Larger in size

because of heavy Framework and Bloatwares*

(ROM Size~844mb+)

3. Touchwiz Got its own specific Features and its own apps for Music/camera etc.

4.they got polish and looks (in own way).

5. High RAM consumption Compared to AOSP.
​

* Custom Roms based on Touchwiz are mostly Bloats free.

**Features varies from Rom to Rom.....get a quicky info in Roms Section!

Recovery Mode and Download Mode

recovery mode- it is a mode used for multipurpose uses.......described below.. :)

switch off the device..hold (vol. up +powe+menu) combination...and let device start..once device start...remove hands atleast from power button else it will switch it on again!!!

How to operate it???

use volume buttons to navigate up and down...

use power button to select!

stock recivery(by default samsung recovery has limited options below....

-reboot system now

(Reboots the system).

-apply sdcard:update.zip

(Install diverse updates like themes, custom roms etc.)

-wipe data/factory reset

(Deletes all the apps, data and system settings(Files on the external SD-card will stay untouched)

-wipe cache partition

(Only wipes (formats) /cache partition (sometimes used as temp storage for updates, market downloads, etc) it hasn't anything common with Dalvik-cache which is in /data by default and it implies that the following boot after wiping cache partition will not be any longer than usually.)

beacuse stock recovery is limited.....custom recoveries are important which have got special features like backup/restore...and many more..

I use CWM...and it is easy to use..i will tell in later section :)

Download mode- it is used to flash firmware by Odin...

Combination - (vol. down+menu+power button)

once it boots ..there will be a screen ..

volume up to confirm that u want to go ahead and flash by Odin.

volume down to backoff and restart if u did it by mistake....​

using ODIN

(lifeline of Samsung firmware installers :P )

it is really simple app fpr windows PC to flash firmwares/kernels/recoveries etc.

when you brick your device, dont panic and post anywhere...just re-install the firmware by Odin for developer's sake :P

it will remove everything and simply will install the Samsung's firmware and will make your device like a fresh new one!

an app for saving asses of guys like me who unwillingly/unknowingly brick there device!!

Odin download

link~ http://bartztech.com/wp-content/uploads/YP-G1/Restore/Odin3v1.7.zip

Odin Prerequisites:-

When you need to flash using Odin, you need the Samsung drivers, so that Odin can detect your device while attached to PC via. USB cable....

- Samsung USB Drivers

linky~ http://www.mediafire.com/download/hzlnda0l5t8qyes/SAMSUNG_USB_Driver_for_Mobile_Phones(3).exe

download drivers

remove old ones installed by control panel(if any)

reboot

install the drivers given

reboot

ready to be used :):)

A stock Samsung USB cable (it seems to give better result than other USB cable bought on third party sellers.)

Flashing by Odin

Note- An Odin flashable file is supposed to be in .tar or .tar.md5 format only.

1.Run Odin.

2. Put your device in download mode(switch off then press vol down+power+menu button altogether.....once it starts..leave buttons else will switch off again :P coz u are holding power button remember !!)

3.You should see a yellow/blue rectangle with COM:xx and saying ready. that is your device ID actually.. It means that your device is ready to be flashed! (It is important because it means that device connected is recognized by Odin :) )

4.Go into the PDA section and take your .tar file.(if single file is given.)

if multiple .tar files are given then put CSC in CSC...phone/modem in PHONE section respectively :)

5. if there is also a pit file then make sure that re-partition box at left is UNCHECKED>!!

6. meditate for a while and ensure once again hat files u have selected are for galaxy grand duos only !!

obvious if you flash s3 files by Odin..you will end up in boot loop.. :P

7. hit start and pray to god that all goes well *kidding*..it will ;)

8.When it's finished, it should say that it's done with a green box saying PASS..if it says fail.....i.e. your USB is not accurately detected...or is detected but disconnects in between.... it happens sometimes if it is not THAT GOOD usb cable...dont panic..remove battery and repeat all steps again!! .just dont let it touched even by air if that happens..keep trying and it will work...once work is done..the first thing u do is get a good USB cable :P(its i am talking about extreme cases , there will be no problem else ;) )

once it is done , device will be rebooted ( if reboot is checked in left box(u will get what i am talking about once you open app and see by yourself) :)

Note:- if you have flashed a firmware..first boot might take time from 3-10 minutes...just keep patience and wait....

if still it doesnt start after 10 minutes ....remove battery...re-insert...go in recovery mode..clear data/format and clear cache..now reboot..wait again.... and you are good to go ;)

ROOTING and CWM

basic reason why most of people come on XDA is how to root!

thanks to [MENTION=4532929]chotu222[/MENTION] who already have made a thread so that people can follow and acquire what they wished!!

i will be short and still descriptive!!!

(as it is already mentioned in forums and its pain to type so much :/)

PROCEDURE:

simply for quick pickers.. install CWM and then flash superUser through it!!

is it really that difficult to do??

there is a cwm given with SeLinux support(which is must for installing kitkat roms ), so why not just install that CWM and be carefree (whatever u flash, it wont give any problem)

simple two steps.....

Step 1

: installing CWM...

here is SeLinux supported CWM file..(thanks to [MENTION=3117667]pawitp[/MENTION] :) \m/ )

linky~ http://goo.im/devs/pawitp/i9082_cm11.0/recovery_20131210.tar

download it and flash via odin :)

NOTE

- while flashing by Odin , untick auto reboot Option(because rebooting device makes stock recovery to over-write over CWM recovery....)

once the flashing process is done....simply remove and re-insert battery, and go to Recovery Mode, flash the Fix-Recovery.zip given below...

that will fix your problem :):)

Fix-Recovery link- http://www.mediafire.com/download/74mmd1x4af6hlo4/Fix-Recovery.zip.

Step 2

: installing superSU: SuperSU allows for advanced management of Superuser access rights for all the apps on your device that need root.

linky~ http://download.chainfire.eu/376/SuperSU/UPDATE-SuperSU-v1.89.zip

just flash the superSU by CWM.....

reboot the device...

and your device is now rooted(check it if there is a superSU app in ur app drawer or not).

that is it!!

that's all it takes to root your device...

just 5 minutes :/

NO..You wont loose any data..its just that you simply installed an app in system root directory :)

Custom roms

Custom Roms are customized Roms for devices..providing us with various different options/advantages over stock Rom what we have Pre-installed by company!..it could be a de-bloated same stock rom w or w/o extra features,/ a whole new version of android/ a ROM based with UI built for different mobile...

simply..there are many Roms and the list is actually long..i cant simply explain but still tried to....

They are mostly based on Aosp/Aokp format(in simple words, with look of nexus UI), or OEM's based(in simple words like Samsung's touch wiz, htc's sense)..

every rom has its unique specialty..unique UI and Unique features.

OEM's are heavily programmed and sized, bloated with factory apps pre-included..

that is the reason that nexus based Roms (~250Mbs+) are twice smaller than the official firmwares(~800Mbs+)!

thanks to all respected Developers who did put such their efforts, and have provided us with so many ROMs !

i am enlisting all ROMs down here with short descriptions, so that you can find everything under one thread here!

AOSP BASED ROMs-

Kitkat (android 4.4.2)

CyanogenMod 11-

thanks to [MENTION=3117667]pawitp[/MENTION] for developing this Rom. i dont think i need any explaination for CyanogenMod :P

its basic AOSP Rom based on Kitkat(4.4.2)...used as base rom for many Custom Roms, It is considered as standard Rom by many Users...Good battery backup,performance and less RAM consumption is speciality of this Rom..it don't implement much extra features except basics, as try to be as near to Nexus stock rom!

developer is always trying to update it as soon as CyanogenMod releases any update...

pawitp has also given delta update Option if you are using limited mbs and internet..its like update and patches which are directly supposed to be flashed (and are <20mbs)..just the modifications made are given , so that you dont download the whole rom...

NOTE- just read FAQ section in cm11 thread for more information on Delta updates.

Carbon Rom

One of the most appreciated Rom Built for galaxy Grand i9082 [MENTION=5273865]xenon92[/MENTION] did put some serious green lantern efforts here :P (the reason why it has got amazing battery backup and performance)

personally, have used many Roms built for the device,but carbon Rom was the one with least problem when Run by ART compiler..

not only its RAM usage decreased from avg. 300 to 210, but also it supports Gapps in ART (while many Roms conflicts with gapps and give FCs in ART)

it has got many add-on features then just plain kitkat Roms...With the possibility of Halo getting Implemented it Near future(Depends on Carbon Team), lockscreen blur, notifications on lockscreen and Active display comprised as its one of good add on features, there is a Good battery backup (actually good,), with performance..

just give it a shot and u will love it ;) :)

SlimKat

One of best thing about [MENTION=5273865]xenon92[/MENTION] is that once he starts rolling new roms, he just cant stop :P ....

so again, introduced slimRom with kitkat power..

slimRoms are most light weight code based Roms , for performance!..they don't add any extra features(Halo and all) because performance is MUST :P

good when it comes to battery backup :)

just install and u will never regret it ;)
