Samsung Galaxy Tab S 10.5

 

Summary




Autoroot process

In january 2015,I have bought this tablet and I got frustrated with restricting rights over microSDcard
So I decided to be a Super-User ( not Superman ! )

I 'm gonna describe the autoroot method, being given that O.S. is Android KitKat.
If you follow the process described hereafter, it 'd be quite fine.

Warning :
- Driver USB samsung must have been set up onto your computer.
- Battery is 100% full up

Process :
1 - Download Odin v3.09 
    Unzip in a directory on your computer.

2 - Download CF_AutoRoot_Port_T800_BeansTown106.tar.md5 
    Unzip in the same directory.

3 - On your computer, run Odin as Admin.

4 - Now, you need to start up your tablet in Download mode.
For that, hit and maintain hit Power + Volume Low + Home as shown.

5 - Then hit Volume up. You 'd see the follwing on screen tablet :

root samsung galay tab S 10.5

root samsung galay tab S 10.5

6 - Usin an USB cable, plug the tablet to the computer.
In Odin, the field under ID:COM must be filled in blue when tablet granted by computer. Watch out :

Odin 3.09

7 - Click AP. Select CF_AutoRoot_Port_T800_BeansTown106.tar.md5
Be careful ! Only Auto Reboot et F.Reset time toggled !
    Click Start. Let's go and wait until finished up.
See what happens in Message zone.

8 - Tablet automatically reboots. Then you may unplug the tablet.

9 -You can now check out whether the tablet has been rooted running a software which needs superuser rights.
    For instance, Titanium backup.


Work out non official status after root

After rooting, the device status becomes non official and a message 'd display, asking to reboot.
You need to proceed as following :
- Open ES Explorer in root mode or Root Explorer.
- Search directory /data/data , rename com.sec.knox.seandroid or delete it.
- Do the same for sec.knox.store.
- Search directory /system/app/ , rename or delete :
    KNOXAgent.apk, KNOXAgent.odex, KNOXStore.apk, KNOXStore.odex.
- Reboot.


Disable Knox after root

(complete the previous column)

Despite root, SuperSU and Triangle Away could come across some issue. Knox is the culpit.
Many ways to disable it :

1 - Using Terminal emulator.
     Run it.
     Give it root access.
     In command line, enter : su pm disable com.sec.knox.seandroid

2 - using Titanium Backup.
     Run it.
     Give it root access.
     Freeze the following :
     com.sec.enterprise.knox.attestation
     com.sec.knox.eventsmanager
     KLMS Agent
     KNOX
     Knox Notification Manager
     KNOX Store

3 - using official way, running Knox then uninstall it. (Parameters)


Usefool tools for superuser

As soon as I'll find out some useful tools (from my point of view), this part 'll be completed.
Besides essential applications as Clean master and Battery Doctor, there are :

Titanium backup : Backup, restore, freeze (with Pro) your apps + data + Market links.
This includes all protected apps & system apps, plus external data on your SD card.
You can do 0-click batch & scheduled backups. Backups will operate without closing any apps (with Pro).⇒ 
You can move any app (or app data) to/from the SD card.

System App remover : uninstall system and user apps.

Total Commander : very powerful file explorer with ftp (I use it on Windows system as well).

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

Terminal Emulator : access your Android's built-in Linux command line shell.

Link2SD : allow moving applications to the SD card, to clean all cache files of the apps.
Format with SDFormatter on Windows (ou EaseUS partition master) to get an « ext » partition read by Android

Root firewall : locks ads, save battery, protects privacy.

Adblock Plus : will filter all web traffic out of the box.

Root Explorer : Files manager with easy changing permissions.

Triangle away : reset flash counter.

Adbd Insecure : let you run adbd in root mode if your device is rooted.

Xposed : framework for modules that can change the behavior of the system and apps without touching any APKs.
Xposed installer : installer for the Xposed framework, which is a requirement for all modules.
Let me point out 3 interesting ones :
→ Xprivacy : prevents applications from leaking privacy sensitive data.
→ Handleexternalstorage : Enables R/W access to the external storage for all apps.
→ Xsuite : change name and icon of an application.

Here is a french link which lists 15 modules very useful : frandroid

SDfix : Android 4.4 KitKat removes your ability to write files to the MicroSD card. SDfix restores it.

Snoopsnitch : collects and analyzes mobile radio data and warn you about threats. (requires Qualcomm chipset)

NoMachine : connect to any NoMachine-enabled computer.

Applications running on Galaxy S5 and on tab S :

 • S-Note : 

 • S-translator : 

 • Calculator : 

After install, updating automatically 'll run.

 • Office Suite Premium : 
View, create and edit complex office and attachments all from a familiar desktop-style interface.

You can do it using SDfix or editing a file in the following way :
- Open ES file explorer, activate Explorer root (bottom left).
- Tap Explorer root again. Tap Mount R/W.
- Toggle RW for /system and /mnt/media_rw/extSdCard.
- Search platform.xml in /system/etc/permissions/ directory.
- Edit it using ES editor.
- Go to line <permission name="android.permission.WRITE_EXTERNAL_STORAGE" >

- Tap Explorer root again. Tap Mount R/W.
- Toggle RW for /system and /mnt/media_rw/extSdCard.

- Add at the end the following lines :

net.tcp.buffersize.default=6144,87380,110208,6144,16384,110208
net.tcp.buffersize.edge=6144,26280,35040,6144,16384,35040

net.tcp.buffersize.wifi=262144,524288,1048576,262144,524288,1048576


- Save.
- Warning : check out rights 644 ( rw-r-r ) of buid.prop now.
      Root Explorer is very helpful to do this.
      Run it, toggle build.prop, tap menu (3 points at top right),
      tap Autorisations. Check out.

root explorer chmod

- Reboot.
