You have to flash the May firmware from sammobile.com via odin. Aug firmware don't allow root.

I kept, having the same problem, it's because of the August update.

You need to revert to the previous update. You can go to sammobile dot com and get the previous firmware for your tablet. Get the latest firmware that does not have Kies. Instructions for how to install it onto your tablet are on sammobile. You'll use Odin 3.09, and once you've flashed the previous frimware, turn off any wifi connection on your tablet so that it doesn't re-update. Then root using the method in this forum and you should be good.

Thank you very much. Now I can reboot in recovery to install the update.zip.

[Galaxy Tab 4 Q&A, Help & Troubleshooting] WanderingElf:
Hello.

I'm new to both tablets and this forum. I've just bought a Tab 4 7" (SM-T230). I've heard a lot of stuff about how rooting is good and great and enhances performance, but I don't really understand what it *IS*. I also don't know if/how it can be done.

I've read the thread but a lot of it is going over my head because I've never done this before (I have a GS3 phone but it runs with the original samsung stuff - please don't throw rotten fruit at me!). Can someone please explain to me exactly what rooting is and does, and why it's so good and useful to do? I seem to be getting the gist from the thread that the 7" tab 4 is a bit of a bugger to get rooted anyway, so failing being able to do that without risking killing it (which presumably would kill the warranty as well), is there anywhere I can find which of the apps I can remove from it? There's a hell of a lot on here that I don't want, don't need, and will never use, but I understand that some of them are integrated with the system and may not be removable without making the device stop running properly.

Any help would be great. :)

Thanks
[Galaxy Tab 4 Q&A, Help & Troubleshooting] raitchison:
Welcome to the site.

Rooting is the process of gaining the most high level privileged access to your device. If you are familiar with Windows it's akin to getting Administrator access.

Getting root allows you to do things that you would not be able to ordinarily, that might mean uninstalling or disabling built-in apps you don't want or it might mean installing and using apps that do things that ordinary apps don't.

For me having a rooted phone is an essential requirement, but it's not without risks. If you make a mistake with a rooted device you could completely break it. You generally do void your warranty when you root but in many (but not all) cases you can restore your device back to it's original configuration to the point where nobody could tell it has ever been rooted.

Here's an article that goes into more detail.

[Galaxy Tab 4 Q&A, Help & Troubleshooting] WanderingElf:
Thanks! I'll read that article when I get a chance to later. :)

I've been happy with my phone without having done anything too strenuous with it (actually only found out about rooting after I'd had it six months and wasn't sure about how to make sure I didn't lose anything). I found out how to disable and uninstall some of the apps I don't use (all hail google), and it seems to work fine. I did feel there were a LOT of unnecessary apps on my new tablet though, but can't seem to find a list anywhere of what's safe to delete. My searches brought me to this site and this thread, but there doesn't seem to be a general consensus on whether or not this tablet roods successfully. Like I said, I also can't find a 'safe to delete' list like I did for my phone. :)

Hello guys. I need your help.

I have SM-230NU, and I need root this.

Here you can see all firmwares for this tablet.

So, on "MAY" ROMz I successfully flashed TWRP recovery by Odin and installed root (supersu) via TWRP recovery

But on "AUGUST" and "OCTOBER" Romz (for example last is T230NUUEU0ANJ1) TWRP recovery is not working, I successfully flashed TWRP by Odin but on Tablet still native recovery. Look screen.

[IMG="Native recovery instead of TWRP after successful flashing that via Odin"]http://s24.postimg.org/f29jdzxur/IMG_20141019_040033.jpg[/IMG]

By VRoot it's also impossible to get Root.

Any sollutions please?

Many thanks in advance.

UPDATE

Problem solved. Just don't let reboot fully after flashing TWRP recovery (via odin) , immediately press volume up+power+menu and you enter into the TWRP recovery, then flash supersu file for root.

Following kuroshka's lead in post #328, I di the following:

This is what I did to get a rooted Samsung Galaxy Tab 4 7.0 (SM-T230NU) on NJ3 firmware.

1. Used Odin v3.07 to flash back to ND9 firmware

2. Turned on USB debugging

3. Configured a WiFi connection

4. Root ND9 firmware with Kingo Root v1.2.5

5. After rebooting, update the SU binary (should tell you this needs to be done)

6. Prepare to flash the NJ3 firmware, UNCHECK the Auto Reboot option in Odin first

7. After flash, click EXIT on that Odin session

8. From the tablet Download Mode screen, boot into Download Mode again

9. Use Odin to flash the TWRP 2.8.0.1 recovery

10. After tablet boots, power off and boot into recovery

11. From recovery, select reboot

12. At the "You do not appear to be rooted" screen, Swipe to install the SuperSU Installer

13. After booting, run the 'SuperSU Installer'

14. I selected the TWRP mode

15. Select 'Continue' to boot into recovery and install SU

16. Reboot tablet and you should be rooted and on NJ3 firmware.

There may be an easier way, but I couldn't find and/or figure it out, but this worked for me.

ATTEMPT AT YOUR OWN RISK!

[Galaxy Tab 4 Q&A, Help & Troubleshooting] devdude:
You cannot flash a custom recovery unless you are already rooted. The procedure above works because I did not reboot after flashing NJ3 and wiping out root, thus being able to flash the recovery. Not a developer, so I don't know exactly why it worked, it just did. :)

Umm...one question before I (possibly violently) return this thing (SM-T237) to the Sprint Store this afternoon....

Does anyone know a way to get Messaging on it?

(WhoDaHayell builds a 4G-LTE device that can't message???)
[Galaxy Tab 4 Q&A, Help & Troubleshooting] brandonmaze:
You can't do traditional messaging with a tablet. You can use an app called MY or mighty text and it will sync with phone.
[Galaxy Tab 4 Q&A, Help & Troubleshooting] FerretPD:
*shakes head*...Thanks for the info, Brandon; I'll look into those Apps......but I gotta say that it makes absolutely *NO* sense.

First off...why assign a Phone # to a device that can't make phone calls, and (supposedly) can't use SMS?

Second....don't say "Tablets don't do Messaging" as if it's some Law...my wife's original Tab (the one we were replacing with this new one) does Messaging just fine...and did so right out-of-the-box.

It never occurred to me that with all the increased memory and processing power...that they would "dumb-down" the device like this.
[Galaxy Tab 4 Q&A, Help & Troubleshooting] brandonmaze:
They assign a phone number to it so it can access the network and communicate with towers. There simply isn't any other way to to accomplish providing cellular data to a tablet. Hotspot devices also have a phone number but can make/recieved phone calls or text messages.

I said can't do traditional messaging. Tablets simply don't do SMS messaging. Most likely you were using some sort of 3rd party preinstalled app that was allowing the messages. I've had tabs on every carrier for the past 4 years and none have done SMS ever.

Hmm - well I just tried Vroot on my new Tab 4 and it didn't work - at least I think it didn't work. The Tab connected to the PC just fine and I ran Vroot. It briefly showed a little USB icon on the left side of its window. I clicked the green button ... and waited ... and waited. And since nothing further seemed to be happening, I ran RootChecker on the Tab and it said no root. I rebooted the Tab, still no root. I ran Vroot again, still no root.

And of course I can't understand any of that chicken-scratching in the Vroot window. For all I know it might say "All your data has now been sent to Peking. Your disk will reformat in 5 minutes."
