Hello guys .. i have samsung galaxy nexus . Stock handset. Never been rooted
I want to root my nexus for first time so i have some confusions in my mind which i want to clarify so that rooting goes smooth
.
Question : rooting erased all the prvious data and apps. I have heard there are some apps which bakup the game and software as well as the other mobile content. Please suggest Some good backup app

Question: i have 4.1.1 currently on device. Does it mean after root only 4.1.1 roms will work on my handset

Welcome to the Nexus club

Here are the answers to your question;

Data Wipe:
Rooting erases all the previous data and apps? NO. The process of rooting only provides you with root access. (But dont be so happy yet

)
As I see, you have a stock Nexus. So before Rooting, you have to do a process called Unlocking. And Unlocking wipes EVERYTHING.

Once rooted and unlocked, when you flash switch ROM's you have to do a clean flash. This removes Apps. But preserves app data and sdcard contents.

Backup:
For backup of data, I'd recommend go for individual apps. The below are my personal favorites for backups:
For app backup, use ES File explorer (It only backs up free app, and no data backup)
For SMS and log backup, use SMS Backup & Restore and Call Logs Backup & Restore by Ritesh Sahu
Contacts and calendar and mails will anyways be synced with google account.

Do all the backups and copy these contents to your PC and then proceed with the Unlocking and Rooting.

Once Rooted, you can use Titanium Backup or ROM Toolbox for data and app backup.

Android Version
i have 4.1.1 currently on device. Does it mean after root only 4.1.1 roms will work on my handset. NO
When I bought my GNex, i was on 4.1.1 too. Currently I am on 4,2.2 ROM's

Hope this helps.
All the best.

Regards,
Neeraj

Thanks for the reply.
I have recently updated to 4.1.1 OTA and notices the battery of my mobile phone is draining quite quickly.
I am thinking to root the device and update it to 4.2.2 (i think its latest available).
Is it possible ? Where to find software to update ?

Once i have downloaded the rom
I have to unlock bootloader, root the device and then flash 4.2.2 on the device. Is it right ?
And when i will flash custom roms on device it will replace the stock 4.2.2 ?

if i flash with any custom rom, will it overwrite the 4.1.1 and is there possibility that it will solve my battery drqain problem ?

yes, it will overwrite.
the battery life is more related to Kernel than ROM; so to get good battery life it would be better to flash a good kernel...

I have seen different tutorials for updating galaxy nexus to 4.2.2. It says something like this

"In order to do the update your device needs to be running build JOP40D"
But when i saw my settings in the mobile, my built number appears to be
JRO03C.I9250JPLH2

Now whats the point here .. ?
how to update the device in this situation

Pirateghost · Feb 23, 2013

fastboot flash system nameofsystemimage.img
fastboot flash boot nameofbootimage.img

arslan_sweeto1 · Feb 23, 2013
