This is a permissive kernel with rooting restrictions removed.
Due to the new security policies in 5.1.1 you will need this kernel to root your device.

This will trip the knox flag thereby potentially voiding your warranty.
I hold no responsibility in any case if you decide to flash this product.

I had a bit of a challenge to get this installed on my SM-T710. I couldn't get Odin to install the kernel using either boot or AP. I did get this working by installing your TWRP build, extracting the IMG file and having TWRP install the IMG file.

What was the issue?

Odin froze/did not complete on the flash. No fail message or even window greying. I tried 3.10.6 and 1.85. After about 10 tries, I decided to use twrp to flash the image and it worked fine.

Same issue for me. Couldn't get it to flash with Odin so flashed the image file via twrp and all is good.

Hmm, I had the same problem but I can't use twrp because when I flash that it says it flashed fine but then I still get the regular stock recovery. Im on 5.1.1

if you already on 5.1.1 ...I believed you have to root first before you can install the TWRP...

I was not sure how did they flashed TWRP without got the Tab rooted first...

more specific instruction ... would be nice...

Thanks

from what i understood they were flashing twrp in odin... from the instructions I read it appeared you could update to 5.1.1 and then begin the process...

Do I need to flash back to 5.0.2 and if so which one? I've got a US 710 wifi.

I just got the root working...

no need to go back for 5.0.2

from 5.1.1 stock..

1-flash TWRP
2-copy t710_5.1.1_boot.img (pulled out from the corrupted TAR) place it in your Tab
3-go to TWRP
4-select install from Image
5-flash t710_5.1.1_boot.img
6-go back download mode, and flash the CF_auto root
7-go back download mode again, and flash the TWRP again
8-go back and verified got Rooted and Custom TWRP

Thanks

The stock recovery gets reflashed by the OS when you reboot. To prevent this from happening you have to reboot immediately into recovery after flashing. TWRP will then patch it to prevent this from happening.

If you disable 'Auto reboot' you can reboot after flashing by holding POWER + HOME + VOL DOWN then immediately switch to VOL UP whilst still holding the other buttons when the tablet restarts.

    5.0.2.....think, there is no 5.1.1 at the moment for Sm-t 815.?...

    Of course, didn't see the t815 bit in your post.
    You need a permissive kernel, I have the t815 source code, so shouldn't be an issue to compile it.
