How to Root N7105

Big Thanx to Chainfire and Chenglu for great work.

You can get root access by A.Rooting your existing and desired ROM or B.Flashing prerooted ROM.

Select your choice from one of this

1. Root with Stock Recovery - It will give full root access but have stock recovery. You can set your flash counter '0' and so ready to claim warranty.If you want device full stock + root this is choice for you.

2. Root + Advanced CWM - This will give Root access as well advanced CWM - Here you can reset counter, but once reboot to recovery, it will raise flash counter, Find option to reset counter on every boot (only play store version).

3.Root with ExynosAbuse apk - simply install apk to gain root access.

1.Root with Stock Recovery

How to Unroot and make status Normal

Restart device and wait for 10 min. and then you can check status.

Reseting Counter

Above method will raise flash counter and you will need to reset counter to reclaim warranty, Read next post for it (post#3)

First thing I do recommend after rooting device

EFS Backup

Why so?

EFS folder contains some important and some basic info related to our device identity like Wi-Fi address, Bluetooth MAC address and the very main IMEI address (nv_data.bin).

Now if this EFS partition accidently corrupted then your phone’s IMEI no. will erased and you can not make voice call further. This kind of damage is often not accepted by the service center of your respected handset’s company.

Here your backup can only be savior for you.

How to Unroot :

- This is commonly needed before sending it to service station and reclaim warranty.

1.As discussed in post #3 if you have any custom recovery/Kernel first you need to replace it with stock one. If you have custom ROM, then you will have to flash stock ROM.(you can use mobie odin to keep root intact to reset counter)

2.You need to use Triangle away if your binnary count is non zero (read post #3)

3.Once your flash counter is 'No' then you can simply unroot from superSU setting

if your device status is -Modified, you can do this trick to reset to normal

setting - appl manager - All - clear data for SysScope as well Enterprise SysScope

This should change system setting to Normal

If still you have modified status, you can wipe cache and data from recovery.

If still it doesn't change status, try removing Ext SD card

4. This is optional but full proof method to unroot and won't leave any footprint of previous root.(provided you flash counter is 'No')

-Flash Stock ROM with PC Odin

-Wipe cache and data.

Apart from described above, you can get root access without raising counter by flashing pre rooted ROM, for further detail read this
