I have followed these steps to the letter yet my device doesn't seem to want to root. Everything looks to install fine but when I reboot no super user and the root checker says no root access found. When I flash the Super User it appears to be fine but when i reboot every time it says it needs to fix root permissions I say yes or I say no and it doesn't work. Could someone assist me with this?

Thanks

Following the guide it was not working, but after reading DroidFanJL post I have made it working fine.

By the way, if i go to twrp and reboot system, it says it need to fix permissions everytime because it can't find super su and busybox, but they are installed and working fine (already tested)

And, if i do a full compressed backup of my entire system it creates a folder with about 20-30MB of files, but in twrp it says it's gonna take about 5GB, what's wrong with this recovery?
Can i switch to CWM or Philz?

I use Philz...
And I guess you can switch..

You'd probally have to re-flash back to stock and start over
new and fresh.
I know it willl take alot of time, but will be worth it in the long run
good luck

No pc

Is there any way this can be done without a pc?
I have mobile odin but it requires root and I have not found a way to root so far.
Please advise

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?

I have the same problem...hope we get an answer

---------- Post added at 03:03 AM ---------- Previous post was at 02:54 AM ----------

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.

I have the same issue with my 3.10

This worked great. Took me forever to get a working download of the stock US version, which to my knowledge Samsung never released on its site - (Cellular South XAR from Sammobile finally downloaded). Towelroot wouldn't work, but this one did. Thanks.

hi guys,
I had same on my uk tab3 - spotted a post in about page 3 that linked to a SU update zip - flashed that and then the SU app seemed to be ok
twrp still says there might be a root issue :/ not sure if it is this knox thingy - not tried to flash rom yet
cheers
dan

...ran root check by Jrummy and says rooted ok - shows binary etc - cool :)
.ran the cf auto root just to be sure - seemed to go ok - reflashed twrp after
...tried rom flash (slimkat) but binary error :/ assume that mean SU bin
fortunately the twrp recovery DID work! :D phew!

I was unable to root properly with the given files, I succeeded though with latest SuperSU flashable in TWRP on my T310XXUBNH1.

TWRP still however complains that the device seem to be not rooted, but you can ignore that. Now I'm just going to do a full backup and put in latest CM ;)

Cannot Turn Off the Screen with the Power Button

After following the instructions the tablet is functioning OK (it is rooted), except for the thing that I cannot turn the screen off anymore. The long press on the power button brings the dialog box for Power off, etc, and I can turn the tablet off. The short press on the power button does NOT do anything anymore!!!

The tablet is SM-T315 with Android 4.2.2 and Build number JDQ39.T315XWUANA1

Please help!

    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.

    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...

    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...
