Sorry for the late response--I've been away for the holidays. Yes, Knox was tripped, but the 1-year warranty was already 2/3 complete so I didn't feel I was sacrificing that much for the benefit of getting root. That rooting your device just to undo annoyances and makes customizations also invalidates the warranty completely sucks. I suspect that one day, a technically inclined judge will call BS on this--at least we can hope so!

Tab4 8.0 rooting problems

I'm trying to root my new Tab4 8.0 to gain full rw access to the 64gb external SD card, which appears to be a very active subject. I've read the articles linked in your post and having some trouble. After downloading, I ran the Towelroot.apk file. However, it appears to go thru the initial process, then reports "app not installed" and goes no further.

Suggestions?

I'm running...

Samsung Galaxy Tab4 8.0 (SM-T330NU)

Kitkat 4.4.2

Kernel 3.4.0-3266519

Build KOT49H.T330NUUEU1ANK1

Thanks much.

Just read your post about a successful t330 root and could use some guidance. All I seem to get out of the Towelroot.apk is "app did not install"

Suggestions?

Thanks much.

Hi all, managed to get myself a galaxy tab on a boxing day sale a few days ago.

Now I'm trying to root my Tab 4 8", SM-T330NU (wifi)

Android version 4.4.2

Kernel version 3.4.0-1337409

From what I can see, there is some success with this version, so I'm hopeful. But from what I understand Samsung has been doing updates that break root, so what can I do to avoid that? I tried reading through all 20 pages but honestly it's all a blur as my thought process is completely disorganized... the multiple models in this topic doesn't help either haha. I was tempted to just go try towelroot but it seems to easy to be safe without doing anything else... like should I back up my bootloader and unlock it?

As far as I can see all I have to do is simply hit the towelroot button and it's done. Am I missing something here? Seems too good to be true...

Cheers
[Galaxy Tab 4 General] slushbilly:
If you have not installed the most recent ota. You can use towelroot and then use titanium backup to freeze the update app so it won't keep telling you a new software update is available. That's what I did. Updates break root.

I was able to use towelroot with the latedt NK1 update. The kernel was built Nov 12th. Am I one of the lucky ones then?
[Galaxy Tab 4 General] evrkusd:
Did you change the parameters of towelroot when you ran it? I haven't gotten it to work successfully on NK1
[Galaxy Tab 4 General] wire55:
No I changed nothing.
[Galaxy Tab 4 General] evrkusd:
So weird. Which model exactly do you have? Can you confirm that you're on 4.4.4? [MENTION=5844563]blazinandroid1[/MENTION] Maybe this would help us get root..
[Galaxy Tab 4 General] wire55:
I have the T330NU on 4.4.2 with november 12th as the kernel buid date. I didn't know the wifi model got 4.4.4.

I have the Tab 4 10 inch with the NK1 kernel dated Nov 5th on 4.4.2 and towelroot won't work for me... Unless I'm doing something wrong. It should be just install towelroot and press 'make it ra1n' right?
[Galaxy Tab 4 General] wire55:
Maybe I am just a lucky one and mine didn't get it patched when I updated.
[Galaxy Tab 4 General] evrkusd:
It may be that the patch that blocks root is tied to the bump to 4.4.4. Your NK1 version is oddly still 4.4.2, so it's likely a completely different build than others are upgrading to.

[Galaxy Tab 4 General] nikagl:
I have done it using CF-Autoroot but it then tripped Kn0x. Someone else said you first need to flash and old kernel, but as I had already installed root I have never investigated how to do this and whether that won't trip kn0x... haven't found any real guides either, so hope someone else has better guides and instructions? My tab was on T530XXU1ANH7, see posts on previous page...

I downloaded Towelroot on my SGT4 10.1 SM-T537A still on 4.4.2 (there is an OTA available but I've been hesitant to do it) but I cannot install..

I only get a screen that says "App not installed" after clicking on the .apk

any ideas?
[Galaxy Tab 4 General] slayerking:
Doesn't work anymore but CF Autoroot does ;)
[Galaxy Tab 4 General] Savagerun:
Yes it does but it also trips knox so your warranty is void if that matters to you.
[Galaxy Tab 4 General] jdmst77:
That's why I haven't used CF Autoroot.

I've used Root66 on my SGS3 and that didn't trip any warranty flags. Does anyone have any option like for this device?

I want to get Kn0x and all the bloatware off this tablet ASAP
[Galaxy Tab 4 General] Savagerun:
Not sure what will work on your model i have SM T330NU and towelroot worked for me. I've used cf auto too which did trip my knox but i don't care about that i just use my tab for one thing and that's to screen mirror to my Roku3 player to get free cable channels using the Kodi app and free movies using showbox app. I was able to dump directv after that and save $120 per month ?. I've owned many android devices throughout the years and never had to use my warranty so that's why i didn't have a problem using cf auto to root.

[Galaxy Tab 4 General] repey6:
Is possible

has long been acting method. Method of replacing the kernel
[Galaxy Tab 4 General] verbage:
mmgill, I have the same tablet with the same kernel. My first course of action was to try Towelroot as that supposedly does not trip Knox, but I did not have success. However, I only tried changing the default Towelroot modstring from "1337 0 1 0 4 0" to "1337 0 0 0 4 0". I subsequently found out that there was a special "New Samsung" modstring "1337 0 1 7380 4 0" (see https://towelroot.com/modstrings.html), but it was too late in my case as I had already turned to the CF-Autoroot method.

All this said, as repey6 wrote, you can supposedly downgrade your kernel to an earlier version that still has the vulnerability that Towelroot uses. And then use Towelroot on that to get root without tripping Knox.

I think there are probably pros/cons for each method so it will be up to you. In my case, tripping Knox didn't really matter too much because the 1 year warranty on my tab is almost up anyways (I got it when it was first released way back in May 2014). Plus, I get whatever benefits/fixes that are part of this updated NK1 kernel. If the benefits of not tripping Knox are worth it to you, well, you will have to do the extra footwork of downgrading to an earlier kernel, and subsequently prevent updates. But this also means that you will not get the benefits/fixes of the newer kernels. To be frank, however, I have never seen changelogs between the kernels (does anybody know where to find them?) so the additional benefits/fixes of the newer kernels may be very small.

Anyway, I would suggest trying the "New Samsung" modstring with Towelroot first, and maybe doing some research on it from that angle. If you have no luck, well, you can always do the kernel downgrade method like repey6 mentioned. Or maybe by that point you'll decide you just want it done and over with so you'll use CF-Autoroot. Good luck with whatever you decide, and if you find out something new, definitely report it back here.

Thanks
[Galaxy Tab 4 General] thisisapoorusernamechoice:
I'm not a dev so I can't tell you what the situation is on roms. But there are always benefits to rooting regardless of roms. You can get rid of bloatware (annoying/useless apps that come pre-installed on stock). You can install adaway, an adblocker that requires root and titanium backup which has a wide variety of uses. With root you can deodex your stock rom and theme it to your liking. Many third party tethering apps require root.

[Galaxy Tab 4 General] jdmst77:
ok, just so that we are clear, the tablet is unlocked but by locked, do you mean that it is AT&T branded (I want to remove the AT&T bloatware so bad)?

oh, so the firmware was downloaded from Samsung and you extracted the kernel from the firmware? I'm not sure how to do this for my model, or which kernel is rootable, or if someone else already did this for my model...

When I first turned on the tablet and it was on 4.4.2 and I accidentally triggered the OTA update sequence (4.4.4 or 5.x, I don't really know?) and couldn't stop it from wanting to update so quickly rebooted while it was unpacking the update and forced a factory restore.

Any advice on where to go from here would be greatly appreciated.

---------- Post added at 02:00 PM ---------- Previous post was at 01:53 PM ----------

won't a custom recovery always trip the warranty bit and/or custom binary download count? If so then would it really help to not trip Knox?

Towel Root worked on Tab 4 8 inch, SM-T330NU

As of 28 Jan 2015, towel root worked on a WiFi (non-carrier) Galaxy Tab 4 8.0 inch, SM-T330NU without issue. A screen shot of my software and kernel version is attached. It says I had the most up to date versions.

1 . I downloaded towel root from the link on the OP. I first made sure system settings enabled debugging and external app install. Check this thread for specifics if you are unsure. Check before asking. It is very simple.

2. After download I installed and ran towel root. My system did not reboot so I knew it ran by simply clicking "make it rain"

3. I downloaded supersu from the Play Store, installed and ran it. I simply followed the prompts to update the binary and disable Knox.

4. I rebooted and installed titanium backup, root checker and ROM Toolbox (my choices)

5. I verified root with root checker, backed up with TB, removed bloat with TB by freezing apps, and tweaked with ROM Toolbox.

6. Disabled auto system updates in system'settings option menu.

When development gets further along I will install a recovery and a ROM but for now running smoothly and happily. Enjoy!

[Galaxy Tab 4 General] thisisapoorusernamechoice:
Not if you follow the directions. I and many others on this forum used this method instead of towelroot. In essence it's basically just using Odin to push SuperSU along with all the necessary files/directories to your tablet; nothing that's already there gets deleted or really even modified. Obviously I'm in no way a developer and can't offer you any sort of guarantee, but I am confident in this method since I've seen it work a bunch of times and haven't heard of it not working.
