Towelroot does the same for the 337a without tripping knox bit. Did it not work for the 337t?

No, unfortunately once knox is tripped, it can't be reset. I'm pretty sure the 337 a and t are identical except for bloat and frequencies and I just used towelroot on mine today. Mines the a

I get "your device is not supported" what mod strings did you use Ive tried a few with no success. also, what kernel are you on ive read the some kernels (may 2014) worked but the one I have (jun 2014) did not

My kernel is here. Didn't use any special strings, just downloaded, installed and pushed the make it rain button.

I went into SuperSU after I rooted my SM-T330NU with CF-Auto-Root and it asked me if I wanted to disable knox - I said yes and it disabled it. I also installed Wanam Xposed and used the Security Hacks feature and Faked the system status to be set to "Official". I also deleted several of the knox system apps with Rom Toolbox Pro and it works great. I can still get OTA update from Samsung and no knox messages and knox is not tripped.

---

when t-mobile tab 4 was released it had a newer baseband n kernel than the other tab 4 devices, thats why towelroot doesn't work on it.
this was discuss in this thread, http://forum.xda-developers.com/tab-4/help/sm-t337t-looking-root-method-t2853724

Does this method alow install custom recovery on t330nu?
I used towelroot and got root access but no luck with a custom recovery such as cwm or twrp would this help or is there any way for custom recovery on t330nu?

I'm not aware of any recovery for any of the 8" Tab 4 models.
If you root and an recovery becomes available (someone needs to make it) you should be able to install it.

This method only works for the t337t. Chainfire makes all of his root methods by Model and uses stock recovery

---

8" recoveries should be on their way soon.

---

Source files have been found and recoveries are in the making.

We have a few developers looking into it. We have distributed some necessary files for the device. Just need to be patient and work together. All is in motion as for a few days ago nothing was really in motion.
Everyone should stay positive, patient and in due time we should all be happy. All thanks and recognition will be made known upon completion. Thanks to everyone helping out great work so far.
