No swipe to root

Hi Guys,

can somebody help explain what I am doing wrong.

SM T230

Android 4.4.2

Kernel: 3.10.0-2376415

dpi@SWDD5919 #2

Thu AUg 7 10:05 KST 2014

Build Number: KOT49H.T230ZHU0ANH2

in Odin

I load openrecovery-twrp-2.8.0.1-degas.tar by using the AP button

On the tablet

I start in to download mode

The screen displays Downloading... Do Not turn off target!!

Odin reports

<ID:0/020> Added!!

in Odin

F.Reset Time is ticked

I untick Auto reboot

Hit the START button

Odim reports:

<ID:0/020> Odin v.3 engine (ID:20)..

<ID:0/020> RQT_CLOSE !!

<ID:0/020> RES OK !!

Top panel displays a blue RESET!

On the tablet.

I power down & restart in Recovery Mode

Odin reports

<ID:0/020> Removed!!

On the tablet

I get the Team Win recovery Project app but no swipe to root option.

Tried the Fix Permissions option (even though I do not know what this does)

This reports Successful

OK, have now installed SuperSU and allowed Root Checker access.

Root Checker now reports the device is rooted.

I would suggest the instructions have a little more detail to help the noobs like me. But thanks to this thread have managed to root the device.
[Galaxy Tab 4 General] LillieBennett:
I went to root and noticed an ota update was pending. Since these interrupt the boot I thought it best to apply it now build ends nk2. Performed root successfully. The only problems was I must have kept bumping the back button because as soon as I released the keys after seeing the download mode/twrp screen it kept rebooting. Looks like the device will not be getting a locked bootloader. The first backup and restore to extSdCard was also successful! :good:

Thanks to all contributers! ?
[Galaxy Tab 4 General] rwcasto:
Confirmed with newest firmware update Nov 7 ANK2

Great work to the devs! Just a couple of things I may humbly add for clarity that worked for me to root my T230NU on the newest firmware.

1. Get your windows drivers from here- http://developer.samsung.com/technical-doc/view.do?v=T000000117

2. Download the ODIN and the SU zip. from OP - place the SUzip on the root of your tablet for ease to find.

3. Enter download mode power+volume down+home button

4. Let your PC finish the install of driver

5. Use the AP button to point in ODIN to the .tar file (do not unpack the tar) then untick/deselect autoreboot, hit start.

6. after ODIN has run it will most likely say "reset" DO NOT DO THIS- hold the power button down 10 seconds to power down

7. Enter recovery by holding "power+volumeup+home" as soon as you see the Team Win blue screen release buttons!

8. In TWRP select install zip, then navigate to your SUzip on your tablet and flash it. reboot and profit.

This was the only way I could get this to root my device- many thanks!
[Galaxy Tab 4 General] ThePeacedog:
Just confirming the method also works with the newest NK2 firmware. Although I unchecked the reboot option, the tablet did attempt to reboot nonetheless. I found holding down the power button to force a shutdown and then rebooting to recovery using the Power + V UP + Home button combination did take me to the TWRP recovery, however, there wasn't an automatic check for root. I suspect this could have been due to the tablet attempting to reboot upon flashing. I too had to use the install option and fortunately had downloaded SuperSu to the sdcard prior to the flash (just in case something like this happened). The install option from TWRP allowed me to install the zip and all is well. Rooted and happy. ;)
[Galaxy Tab 4 General] ramzidjoudi:
nice work

is that TWRP fully working (all features work great)

thank you

Odin 3.09 won't open

I have the Tab 4 7.0 (t230nu) I've downloaded the Odin 3.09 from post #45 and it will not open on my pc, it flashes real quick on screen and disappears.. can anyone help me with that. I'm trying to root my Tab. Thanks in advance
[Galaxy Tab 4 General] LillieBennett:
Probably a bad download, have you tried running it from a command line, it will let you see the error message.
[Galaxy Tab 4 General] PhoneCollector:
Odin 3.09 won't open

Hey thank you for the reply, I downloaded again, and it worked!!
[Galaxy Tab 4 General] Colbert87:
didnt work

odin completed successfully then rebooted into recovery but still went to the stock recovery (power-v up-home) just straight to stock

Update: finally got it to work after flashing with odin 3 times i finally released in time to catch it in twrp youve got to be super friggin quick lol
[Galaxy Tab 4 General] LillieBennett:
Well if you turn off the reboot switch it gives you more time. Some catch it during reboot, some power off then enter with the tri-switch method and some just use the tri-switch from there. I believe they all work (I used the latter).
[Galaxy Tab 4 General] ThePeacedog:
I had to catch it on reboot and hold down the power button to force the shut down even with the reboot option unchecked in Odin. From there I use the three finger salute to get into recovery and then used the install option to install SU. ;)
[Galaxy Tab 4 General] jdblaze:
Probably not a good idea to try and use Odin via WINE on linux, eh?
[Galaxy Tab 4 General] ThePeacedog:
From Linux you may want to try Heimdall.

http://glassechidna.com.au/heimdall/

The tablet isn't on the tested device list, but it's probably safer and easier than trying Odin with Wine.
[Galaxy Tab 4 General] c-prodigo:
Save yourself the trouble, I tryied in linux mint virtualbox, even got odin to recognize the tablet in download mode using windows 8, after that it wouldn't flash any way, find a windows pc and do it there.
[Galaxy Tab 4 General] jfriend33:
So here's my question. Sorry for taking thread off topic.

I got one of these galaxy tab 4 7.0 from staples for $99. It's a gift for my 13yo nephew. To replace his 2011 kindle fire.

I rooted his kindle only to install a launcher and block the special offers. He's never got in trouble or had problems from installing something he shouldn't.

I am beginning to think I should probably just give it to him stock. Then if he says it's laggy then root, add greenify and Tasker and a few xposed modules to improve battery life.

Thoughts?
[Galaxy Tab 4 General] LillieBennett:
IMO don't think that these devices will ever be locked so you should be good to wait. You can count on ads though lol!

New to android rooting

Hello,

I have no idea what I am doing I downloaded the links specified but I am not sure if I am supposed to be putting them on the tablet itself or how I am supposed to access the files these android tablets are nothing like my blackberries

what does flashing mean?

I was able to get the tablet into download mode but had no idea how I was supposed to que up the files that I downloaded from the thread. I know I sound dumb but can I have a step by step how do I do this. Do I transfer the files over to the tablet once I download them to the pc or do I download the files direct to the tablet. Do I need to download winzip? I just don't understand this it is very different from what I am used to and where is this ODIN 3.09 I have not seen it, I did get the TRWP and the recovery but .... I am very confused:confused:
[Galaxy Tab 4 General] ThePeacedog:
Hi, Welcome to XDA. The instructions are in the first post of this thread. If you're crossing over from BB devices I suggest you just spend some time using the tablet first and see if you really need root for anything specific. Get yourself oriented in the Android OS or in the case of this tablet, Samsungs version of Android with the Touchwiz interface. Just having root on the device for the sake of it doesn't really make sense in my opinion. If you root with no particular function in mind you may just lower the security level of the device with no real benefit. If you find you need root for something specific just come back to the first post. ;)

Worked on my 530NU, 10.1, as well. Thank you.

TWRP 2.7.1.0 Galaxy Tab 4 10.1 [SM-T530] and UPDATE-SuperSU-v2.37.zip and Odin 3.09
[Galaxy Tab 4 General] Whiteouttonight:
Really!! Thats Great to hear!! We just purchased, for my daughter a 230NU 7.0 and a 530NU 10.1 for myself for Christmas( both wrapped under the tree for now). Good to know I can use a single method to root both when we open them. I have way too many Samsung products in my home now, now I really gotta get my Son off that dang IPAD mini.
[Galaxy Tab 4 General] Fiddlin:
Stuck

Hi.. I have a SM-T230NU

I started to follow these directions:

doesnt matter now. rooted without the vroot help.

i just flashed TWRP recovery thru Odin 3.09 then it detects that im not rooted and it rooted it few clicks

1.) download Odin 3.09 and TWRP(recovery.tar) - all attached

2.) put tablet on Download Mode (Power Button+Volume Down+Home Button)

3.) flash the recovery.tar thru Odin 3.09 use PDA/AP button on Odin

4.) put tablet on Recovery Mode, this time it would be modified recovery TWRP (Power Button+Volume Up+Home Button)

5.) reboot device, TWRP will detect that tablet is not rooted and ask if you want to intalls root. Slide to Install

6.) find SuperSU installer, follow instruction to install.

7.) download RootChecker to verify root

File Type: zip	Odin_v3.09.zip - [Click for QR Code] (973.8 KB, 1096 views)

I did the following. No more than this. I think I'm missing steps...

I downloaded the 2 files to my tablet. Did nothing else with them.

Put tablet into Download mode. Screen said "Downloading... Do not stop target!!" Waited.

Nothing happened. I restarted the tablet.

I've been reading this thread... is the NU an issue? What am I missing? From my limited past experience in rooting, there are usually details left out that experienced rooters would know automatically. Fill me in?

Thanks.
[Galaxy Tab 4 General] Carlyle_f:
Boot straight into recovery after flash twrp. This means, as soon as the tablet restarts from download mode, hold the volume up + home buttons.
[Galaxy Tab 4 General] Fiddlin:
Do you mean once the tablet restarts INTO download mode... when I see the "Downloading.." screen... I just hold the buttons to reboot right away? Nothing is happening from the Downloading screen automatically for me. It does not restart from download mode by itself if that's what you mean. Thanks.
[Galaxy Tab 4 General] Carlyle_f:
Reboot into recovery yes

Sent from my AOSP on Tilapia
[Galaxy Tab 4 General] Fiddlin:
Nevermind I found the info looking at the root of something else. I have to download the files to my computer, connect the tablet and run them apparently. If that's wrong please let me know. Thanks!
[Galaxy Tab 4 General] ThePeacedog:
That's correct, you flash the recovery file to the tablet which should be in download mode from Odin which you run from your pc. You connect up via usb. Good luck. ;)
[Galaxy Tab 4 General] Michele31415:
"3.) flash the recovery.tar thru Odin 3.09 use PDA/AP button on Odin"

Does this mean to put the tar file in the AP line of Odin? I don't see anything marked "PDA/AP" in Odin 3.09.

Also, which Option boxes should be checked in Odin? It comes up with "Auto Reboot" and "F.Reset Time" already checked.

I just don't want to brick my Tab.
[Galaxy Tab 4 General] ShinySide:
Says PDA/AP because in Odin 3.07 and older versions have a PDA slot, 3.09 they renamed to AP. So depending on which version you use, either PDA or AP.

Uncheck auto reboot, when trwp is done flashing, unplug hold power til it shuts off, and reboot DIRECTLY into recovery before booting into android
[Galaxy Tab 4 General] Michele31415:
Thanks for the clarification. I did the Odin part OK and rebooted into recovery. Now I'm stuck on this step:

"5.) reboot device, TWRP will detect that tablet is not rooted and ask if you want to intalls root. Slide to Install"

I've got the TWRP menu on the screen with 8 items (Install, Backup, Mount, Advanced, Wipe, Restore, Settings, Reboot) but it's just sitting there. It doesn't seem to have detected anything and it hasn't asked me if I want to install root. What do I do now???

Scrolling back to msg. 119 in this thread I see someone wrote:

1. odin nj3 (canada version on US tab4 t230nu...not sure if that matters)

2. odin the recovery

3 boot into recovery

4. did nothing tapped reboot.

5. msg came up to install root

6 reboot and verified root

7. ran xposed again, titanium apps i dont need

8 all good

Is that what I should be doing? I'm basically on step 3 of the above list.
[Galaxy Tab 4 General] ShinySide:
Yea
[Galaxy Tab 4 General] Michele31415:
OK, so I tapped Reboot but now I'm looking at something called Reboot Menu with four new choices: System, Recovery, Power Off, or Bootloader. Which one?
[Galaxy Tab 4 General] ThePeacedog:
TWRP recovery is where you need to be. I had put SuperSU on my sdcard prior to installing the recovery so I used the install zip option. Others reported that TWRP asked to install SU and they just followed that. Try rebooting to recovery again and see if TWRP requests SU, if not you might want to grab the apk and put it on your sdcard then you can use the install zip option from TWRP.
[Galaxy Tab 4 General] Michele31415:
"Try rebooting to recovery again and see if TWRP requests SU, "

Well duh! Thanks! From the Boot Menu, I clicked on "Recovery" and hey presto it said "Install SuperSU? Your device does not appear to be rooted. Install SuperSU now? This will root your device." (Swipe to install).

Well hell yeah, so I swiped to install and this brought me right back to the TWRP main menu after what looked like a quick reboot. So *now* what do I do? The choices are Install, Backup, Mount, Advanced, Wipe, Restore, Settings, or Reboot.

And if I Reboot, there's more choices after that.

(And I do not yet have the SuperSU zip on the Tab).
[Galaxy Tab 4 General] ThePeacedog:
Reboot into full Android, go to the play store and install root checker to verify. You should be good to go.
[Galaxy Tab 4 General] DUHAsianSKILLZ:
Just reboot, then hit system. Then supersu should one of your apps. If it's not there then you might need the zip.

[Galaxy Tab 4 General] reaper000:
For anyone who's wondering, the latest official supersu zip is available here: http://download.chainfire.eu/supersu

You should open the above link in your tablet's browser, causing the zip file to be downloaded into the download folder of the tablet. That way when you've Odin'd the custom recovery onto your tablet and rebooted into recovery, you just have to install the downloaded zip.

Thanks to the OP for this!
[Galaxy Tab 4 General] Michele31415:
Thanks! I hit Reboot on the TWRP menu, then System. The Tab rebooted into normal Android with a message about upgrading system (I think that's an Android OTA update that arrived overnight while I was waiting for this - I put it on hold). I downloaded the latest SuperSU (thanks for the link!) directly onto the Tab from the Tab's Internet browser, clicked on the download line in the Notifications, clicked on Play which opened the SuperSU page in the Play store, clicked on Update, waited for it to finish, pressed the Home button, opened RootChecker, tested for Root and ... YEE-HAH *** we have root ***!!! Whew!

So I can confirm that this method works just fine on the SMT230NU, US WiFi version, with NJ3 (Oct. 14) firmware.

Many many thanks to ShinySide, reaper000, ThePeacedog, and DUHAsian SKILLZ for taking the time to help me out with this. It is very much appreciated. Now I can actually use this tablet.

UPDATE

I should add that this root method changes the System Status from "Official" to "Custom". But this is easily fixed with the awesome Wanam Xposed app. In Wanam, go to Security hacks -> Fake system status and check that. Reboot, done. System status in About device is back to Official.

root an encrypted tab4 T230NU

I attempted to root my T230NU encrypted using the TWRP method (thanks!!) described in this thread. I got it encrypted and did not decrypt first because I did no think it would need the data partition. Everything went well and as described in the posts, however root checker does not detect root. The superSU Installer was installed as part of the process in TWRP but when I attempt to install the app itself, I see some error messaging that it cannot access /data. I tried factory reset, and decrypting the device but all failed. It is still encrypted, the recovery is custom, system modified but no root.

Any suggestions to bring the device to original condition. Or, achieve root?

thanks
[Galaxy Tab 4 General] ThePeacedog:
I would flash back to stock using odin then install the recovery again. You should be able to get your stock firmware from sammobile.

[Galaxy Tab 4 General] 2clubbers:
I don't know what am I doing wrong.

I've flashed the file via Odin and then I want to go restart to TWRP directly from Download Mode by pressing Power+Vol Up+ Home.

But then system don't want to Enter to TWRP only the TWRP logo blinks and there is Samsung Animation.

Can you help me ?
[Galaxy Tab 4 General] kurbag:
That part was tricky for me, too. I had to try several times. So, try releasing the Power button after you did the combination of buttons.
[Galaxy Tab 4 General] ThePeacedog:
Have you tried powering the device off and then booting to recovery? Give that a shot and see what recovery is there. If you don't boot directly into TWRP after the flash, the system can overwrite the twrp recovery with the system recovery.
[Galaxy Tab 4 General] jdmsohc22:
So I just got a Samsung Galaxy Tab 4.0 7" for Christmas! It's running 4.4.2, it's an SM-T230NU, and the build is KOT49H.T230NUUEV0ANH1.

I've been rooting Android phones for quite a while now so I'm very familiar with the rooting process, but this is my first tab! So do I just follow this method here and I should be able to boot into recovery and backup/flash etc..??

Thanks!

Wow, that was the easiest root ever!! Sweet, thank you!!

I see there isn't an overabundance of ROMs for this platform, that's kind of shocking figuring it's pretty popular right now..!

Should we expect to see some development with this in the future, or is there a reason that dev's aren't messing with it..??

Thanks again & Merry Christmas!
[Galaxy Tab 4 General] sidthunder:
Forgive me if I didn't see it anywhere in the thread, but did anyone confirm if this procedure tripped the Samsung Knox Counter or not?
[Galaxy Tab 4 General] ShinySide:
There isn't one on the 7
[Galaxy Tab 4 General] sidthunder:
OK, so the Samsung Knox Counter doesn't exist on the Samsung Galaxy Tab 4 7.0 SM-T230NU. Thank you very much!
[Galaxy Tab 4 General] thelous:
Wow, i think this isnt very easy at all, you have to boot recovery on first boot. I dont always end up to recovery even with normal reboot and button combination. I think one click roots r way easier!
[Galaxy Tab 4 General] ShinySide:
Make one then.
[Galaxy Tab 4 General] Zephead:
That was easy!

Just got this tablet for Christmas (8GB T230NU) and followed the first post and now I have root and customer TWRP recovery, made a backup already to the 32GB micro sd card I installed and I'm ready for Rom flashing, thanks!
[Galaxy Tab 4 General] jdmsohc22:
Obviously a one click root is the easiest, but with the lack of one yet for our platforms, this was a very simple and straight forward process.. I remember the days where it required ADB pushing/receiving of certain files to get root, and that was only one step of about 15 lmao..
[Galaxy Tab 4 General] hoopas:
By far the easiest root method I've tried in my years of flashing. Thanks OP. Regarding new Roms, its still early in the game I think but they will come. Till then xposed all the way :thumbup:

What would it take to make a custom rom for this tab.?? I'd love to give it a go..!

cant boot into TWRP

Hello. I followed the steps:

1.) download Odin 3.09 and TWRP(recovery.tar) - all attached

2.) put tablet on Download Mode (Power Button+Volume Down+Home Button)

3.) flash the recovery.tar thru Odin 3.09 use PDA/AP button on Odin

4a.) put tablet on Recovery Mode, this time it would be modified recovery TWRP

. . . but when I go into recovery mode it will never go into the TWRP recovery mode. Ive tried to flash it serveral times with Odin, no luck. Any ideas. Thanks
[Galaxy Tab 4 General] tatoo069sv:
I had the same problem when I did mine yesterday. Make sure your twrp is the correct version mate. I think you need 2.8.0.1 dega something like that.
[Galaxy Tab 4 General] Bob_in_RI:
Same problem with TWRP 2.8.0.1 and NK2 firmware. Flashed back to NE2 firmware and it works fine.
[Galaxy Tab 4 General] exsheeple:
[MENTION=5186754]tatoo069sv[/MENTION] - I verified the version was correct

[MENTION=5741261]Bob_in_RI[/MENTION] - so the NE fireware will root the device?
[Galaxy Tab 4 General] Bob_in_RI:
Yes, I was able to root with NE firmware.

But, just to be sure, I tried again with the K2 firmware. I noticed on another thread that it was important to turn of Auto Reboot in Odin. After a couple of tries, it worked! You just have to be sure it boots into TWRP first, this seems to be the key
[Galaxy Tab 4 General] exsheeple:
Yeah, that seems to be the big issue I'm having. . . .cant boot to TWRP
[Galaxy Tab 4 General] Bob_in_RI:
All I can tell you is that you is that I turned off the Auto Reboot and F Reset Time in Odin, flashed TWRP, waited about 10 seonds after it was done, unplugged, and rebooted while holding down power + home + vol up. If it goes to factory recovery, you have to reflash and start again.
[Galaxy Tab 4 General] ThePeacedog:
I had to unplug the usb and hold the power button of the tablet to force a shutdown then boot to recovery. If you don't boot directly to the twrp recovery after the flash the stock recovery will likely overwrite it. Some have had luck with the timing of the shutdown and booting back to recovery, but I actually had to force the shutdown. YMMV.
[Galaxy Tab 4 General] thelous:
Oh, well my first root was just installing a zip in stock recovery XD tht was when android 3.2 was newest android....
[Galaxy Tab 4 General] ThePeacedog:
My first was a little complicated, had to use adb shell to execute a script that ran the tool on the device to get root. Took quite a bit of reading and learning to get where I needed to be. I was fortunate that I had a Linux background so the learning curve wasn't as steep for me as for some others I remember at the time. Honestly, this could've been a lot tougher. The recovery wasn't locked or blocked in any way so it's been quite refreshing compared to some others. :laugh:
[Galaxy Tab 4 General] azpatterson3:
Super easy root. I've rooted a bunch of devices and this one went with no problem. Didn't even need adb. Just Odin and twrp. Thanks for the directions and downloads.
