Greetings All. I jsut have a few questions.
I just purchased a refurbished Galaxy Tab 3 8.0 with JB on it. The update downloaded but I did not install anything. In fact, i turned off wifi so it does not try to force any installation of it once I reboot it. My question(s) are can I use this method to root my Tablet on JB? Once rooted and TWRP is installed can i flash any KK rom or JB rom? Or am I jsut stuck with JB since the Tablet originally came with JB?

Thank In Advance for any response and help..

I just downloaded the Cellular South Galaxy Tab 3 8.0 firmware from Samfirmwares and used ODIN to flash, no issues at all. You'll need to create an account to DL from here though. My apps and custom launcher were even still there. I was rooted as well so you shouldn't have any problems updating over a rooted 4.2.2 if you know what you're doing, and it seems you do.

I used this cf autoroot version especially for this product and root is enabled, FYI.

Somehow he got the 4.4 update even though I didn't do anything. I wonder if he might have sent his tablet in for service and they reset it. I'll check.

hmm... i have a SM-t310, with KitKat 4.4.2 on it. Performed all the steps in post one... First time I did the root via the TWRP Reboot>System... used Root Checker and it said it said Root Access=no access. Tried rooting via the SD Card. Again everything seemed to go fine, but again Root Checker and it said it said Root Access=no access

any idea what could be up?

Not completely sure, but with the new sd card permissions on Kit Kat, it may not work to use sd via recovery. I tried a custom recovery from my sd and had to reflash root using Odin because I think knox tripped and it restored the original recovery instead. I had success rooting via Odin only.

Galaxy-Tab-3-8.0-Root-TWRP.jpg


The latest iteration in the Galaxy Tab series, the Galaxy Tab 3, has a lot going for it. The Galaxy Tab 3 8.0 specifically features a 5MP camera, 16 or 32GB of onboard memory, a dual-core 1.5GHz CPU with 1.5GB of RAM, and as its name suggests, an 8-inch touchscreen display. The device is now rootable and also has a custom recovery ready to be flashed, so custom ROMs should also be on their way pretty soon. The guide below should help you get ready to flash custom ROMs, by way of rooting the device and install custom recovery (TWRP Recovery in this case).

I. Before You Begin
1. Make sure you have backed up everything you care about from the device before you begin.

2. Charge your device to 75% or more before you start.

3. Install the proper drivers before you start. Usually, installation of Kies will take care of this.

II. Necessary Downloads
1. Odin307.zip

2. TWRP_T31x_r3.tar [or the latest version from this post under the Downloads section]

3. ROOT_SGT3_8.0.zip

III. Installing TWRP Recovery on the Galaxy Tab 3 8.0
1. Extract Odin307.zip to a folder on your desktop.

2. Copy TWRP_T31x_r3.tar to the extracted Odin307 folder.

3. Double-click on Odin3 v3.07.exe from the extracted folder to start the Odin tool.

4. Power down your device and put it into download mode. To do this, press and hold the Home + Volume Down + Power buttons simultaneously for 3 to 5 seconds until you see the warning screen.

5. Connect your device to your Windows PC using a compatible microUSB cable. If your PC installs drivers at this point, let it do so. Once that is done, the ID:COM field on Odin should light up yellow, signifying that Odin has recognized your device without a problem. If not, make sure you install the proper drivers (by installing Samsung Kies) and try again.

6. Click on the PDA button on Odin and navigate to the location of TWRP_T31x_r3.tar to load it on to Odin.

7. Wait for the PASS message on Odin and reboot your device.

You should now have TWRP Recovery installed!

IV. Rooting the Galaxy Tab 3 8.0
1. Boot into recovery by powering down the device, pressing and holding the Power + Volume Up buttons until you see the Galaxy Tab 3 splash screen and letting go of the Power button once you see it. Continue pressing the Volume Up button until you get to TWRP Recovery.

2. Hold your device in portrait mode, and tap on Reboot on the bottom right of the screen and then select System on the next menu.

3. You will be asked to install root. Accept it and the device will reboot.

4. Follow the on-screen instructions that will now appear after your device has powered on.

V. Alternate method for Rooting
If the section IV steps failed to obtain root, here is an alternate method to get you going.

1. Copy the ROOT_SGT3_8.0.zip you downloaded above to your internal/external SD card.

2. Boot into TWRP Recovery as detailed in Section IV > Step 1.

3. Tap on Install once in TWRP Recovery.

4. Navigate to the location of ROOT_SGT3_8.0.zip and select it.

5. Swipe to confirm the flash.

6. Go back to the main menu, tap on Reboot and then tap on System.

You should definitely be rooted after your device reboots. To confirm, install Root Checker Lite from the Play Store or any other root requiring app and you will prompted to grant root access via the now-installed Superuser app.
Was able to install Odin and p_s g_t root file directly to my tablet so when I plug it in I can transfer them over to my computer with the TWRP link after 5 seconds on the download page it tries to make me install an app called mobogenie and I have to disable wifi on my device and force stop the application after which I can close all the tabs and clear my history and cookies. Can someone direct me to another place where I can download the tar file?

Odin tool installs malware

I downloaded Odin 3.0.9 from its official site(google for it, I cannot include a link)
Beware, this tool installs lots of malware- including browser add-ons, different search engine, and more (it does give you warnings in the form of license agreements, that most people never read).

i was lucky to notice...

For T311 Android 4.2.2 Unlocked Phone

Thank you for the excellent instructions! However, was not able to access TWRP screen until I first rooted using a different method, designed for unlocked T311 with Android 4.2.2. Once rooted, I was able to access TWRP and install a custom recovery.

Here's what I did:

1) Rooted using Team Android instructions [google: "How to Root Galaxy Tab 3 8.0 T311 on Android 4.2.2 Jelly Bean Official Firmware"]

2) After I rooted, I tested my root with an android root testing app.

3) I then I followed all the instructions again and it worked.

Thank you.

hello people, developers and users. Please help me.
I need guidance in installing custom roms on my tab 3 8.0. It is a wifi + cellular device. I got bored with jellybean, and wanted to experience kitkat. I have successfully rooted my device. I need proper guidance in installing roms.

I have tried CyanogenMod 4.4.4 and LiquidSmooth 4.4.4 roms, but at the TWRP Screen when it asks to install the zip files, viz. the custom rom and GApps, it fails and gives an error saying, THE MD5 IS MISSING.

pls help me people.

There is a new kitkat touchwiz rom available for T311 3g model. You can install it for kitkat experience instead of a custom rom. Download it from sammobile

Great instructions. Personally, I go for Philz instead of TWRP.

Problems

I faced the following problems while trying to root my SGT3 t311 .
Odin recognized my tab when i connected it to the pc while it was on but did not recognize the device in download mode.
I dont think it is a driver problem because it connects to the pc while on.
Any idea what is wrong?

On my TAB 3 ( SM-T311) running on 4.4.2 stock firmware( unrooted), I flashed twrp recovery by odin, successful!.
But then in recovery mode when I click on reboot and then on system, it asked to root my device. A superuser app was installed .
I tried to run that app but it says that my device in not rooted fully and I verified it with root checker.
App offered me two chices to root my device either google play( updating the super user app) or twrp, I choosed to go with play and I updated to supersu app.
But not rooted yet!
SuperSu app says:
"There is no SU binary installed, and SuperSu cannot install it. There is a problem!
If you just upgraded to Android 4.3, you need to manally re-root - consult the relevant forums for your device!"

What should I do now?
Should I try to root by odin?
If so , do I need to unstall SuperSu? Please help.

    This thread is for Android 4.2.2 but will not work with Android 4.4.2

    I successfully rooted with this:
    droidviews.com/root-galaxy-tab-3-8-0-sm-t310-on-kitkat

    Then Installed custom recovery,
    philz_touch_6.19.3-lt01wifi.tar.md5

    My model # is: SM-T3100ZWYXAR

    yeah was wondering the same.. also does anyone know if a rom from the 7 or 10.1 section can work on the 8?

    No they won't sorry. All Galaxy tab sizes are based on different chipsets.

    Yes this will work on most current stock firmware as well.

    Simple, painless. (SM-T310) Thanks eeamshh worked a charm. Be sure to uncheck auto reboot in Odin folks and all will go smoothly. Power Tab down manually once Odin finishes and 3 button combo into TWRP. I used the alternate method installing .zip from SD, got a custom binary/system status count but whoop dee do da, such minor details never bother me. AdAway here I come...
