Still having Tab2 woes

I have an earlier thread here http://forum.xda-developers.com/showthread.php?t=2107600 but that is now buried on page 2 and might be missed by new readers. After a disastrous time trying to root my Galaxy Tab 5100 I did manage with the help of people here to flash the recommended stock ROM - however while the tablet goes through its boot sequenece with the aminated Samsung sign - it sticks when it gets to the plain Samsung logo and wont go further.
Odin reported that it installed OK and the tab rebooted as it should but only this far - not sure what I should try next to get my stock Samsung image back and working. One thing I didn't do was to tick repartition because the instructions only said to do this when a certain type of file was included in the package, and it wasn't. Should I have ticked this after all, if so I can try the same thing again if I can force it back into download mode again. (though as the yellow pane still shows in odin when connected I wonder if I can just go ahead anyway)
I have also been looking for rooting software and came across this
http://root-android.org/?version=Tablet&country=Samsung&ios=Galaxy+Tab+2&submit.x=63&submit.y=104
I am wondering if next time (assuming I ever get it working!) I would be better shelling out $30 and getting software to do it all for me - is this any good? has anyone used it or had reports about it? I wish I had seen this before I read "that it was almost impossible to brick the tab 2"
Also I would like to have root access on my S3 as well but wouldn't dream of risking this I don't think now

Have you tried a factory reset from recovery? If you've restored the stock ROM, then all you need to do is the factory reset to get things working again. Don't repartition unless you really need to.

I can't see any reason you should spend that kind of money given how easy the CF-AutoRoot is. In fact, that product looks very shady to me. "Root Any Android Device"? Well, there's lots of devices out there that nobody's been able to root, or devices that take a lot of work. I can't believe there's a single app that'll work across every Android device with a single click.

Be careful, which stock ROM have you flashed? I would use this sequence
flash the stock ROM
then immediately
flash CWM recovery, use CWM recovery to wipe the data (wipe data/factory reset).
Then reboot

CWM ?

Well I followed one of the posted routes on this forum, downloading from a list of recommended files for each version, and it mentioned nothing about CWM which I know nothing about. I have to say that everyone's definition of "easy" on here - I find complicated and difficult - I know my way around windows but android seems much more complex. The only reason I wanted to have root in the first place was to be able to make a complete image back up that would make it easy to restore my device without having to re-download all my software and set up. I do it with windows all the time. To me "easy" is, download and install something - click go - done! Even getting the device to go into download mode in the first place is a very hit and miss affair (as others say on here too) clearly Samsung don't want you to do this.
The other problem is that while the tablet is in this state it wont turn off, just reboots itself when you do and the screen stays on - so unless you leave it plugged in 24/7 - I start each time with a flat battery that I have to recharge before I can try something else

This is the route I followed

I got this through earlier posts - the only thing I didn't do was to go into recovery and reset in step 2 because this simply wasn't possible - the device was stuck on the error message and no amount of button pressing did anything other than restart to the same screen. By this stage I couldn't even go back to check what version of android I was running - it would have been the latest jelly bean distributed to UK.
I also didn't check re-partition as in 6. because there was no pit file in the download
E. Restore to stock

8. Click Start.
9. Enjoy!

Help please - this is where I am at the moment - some SIMPLE help needed please
I tried to install what I thought was the stock ROM - it appeared to install but wouldnt boot past the samsung screen. I now realise (a) that I may not have followed the full correct procedure and (b) may have downloaded the 5110 rom instead of the 5100 rom - silly mistake I know.
However reading all the guides I can find there doesnt seem to be a simple way I can find of restoring the standard un-rooted rom so that I can go back and try again. All of the things I can find seem to included downloading something onto the external card but cant do that as I cannot access it and don't have an external card reader.
What I can do now is
boot into download mode
connect to ODIN and see the yellow block
It will not boot normally past the samsung splash screen
and cannot connect to KIES in any mode (I do have the drivers installed and have connected before)
I also have no idea now what is installed on it because I cant get to the system to see!
Is there an easy way to install a stock samsung rom from this point? I don't mind if data is lost, I have nothing important on there and wouldnt mind re-installing apps as I had accumulated far too many anway - really I just want to get my tablet back the way it was from the factory but with the 4.2 jelly bean installed (though if it went back to an earlier version and I could update in Kies that would be ok too)
Can anyone give me simple instructions for doing this using just ODIN and my computer without involving the external card - please.
After that I will be looking for an equally easy way to root it again
I will credit you with a good answer if you can help -as well as appreciating it.

What you need to do is to download the stock ROM for your 5100.
Go to www.samfirmware.com and put "GT-5100" into the search box. You'll see a list of the stock firmware for your device. Pick the appropriate firmware for your country and click "download".
Start up ODIN. Click on the "PDA" button and open the firmware file you downloaded above.
Restart in downloader mode (power and volume up), and connect the tablet to your PC. ODIN should now show the device.
Make sure repartition is not checked, and click on "Start". When it finishes, you now have stock firmware installed.
Power off, then restart in recovery mode. (Hold power and volume down.)
Choose "wipe data/factory reset" by using the volume keys to move the highlight, then pressing the power button to select an entry.
Once it's finished booting, you should be back to normal.

Thanks K1MU for this information which at least looks clear - the only problem I have is when I put in the model etc when I get to country it offers me only 3 choices
UK (BTU) GB (O2) or GB (vodafaone)
My phone was purchased from Amazon and is unlocked so I am worried if these might lock me to a carrier which I wouldn't want
I wonder if BTU is the unlocked one as it doesn't sound like any provider I know - but I am not sure
will post on their forum as well

I think I am getting more and more muddled by the minute (sign of old age I fear) I realise now that I have a p5110 - wifi only and not p5100 3g and wifi.
This means in all probablilty I downloaded the correct rom in the first place. As I had not done the factory reset afterwards so tried that - it appeared to work ok but when I restarted it just played the samsung tune and moving image - then went to "Samsung" and stuck there as it was before.
I am downloading the p5110 wifi only rom from Sam's site - awful download programme they use which doesn't accept paypal even to sign up for faster downloading - I will then try following exactly what you have suggested and keep my fingers crossed

thank you

Although I thought it had got nowhere after wipe restore - when I turned it back the next day I arrived at the start up guide - admitedly it was 4.0.3 and in Portugese but after exploring settings and working out what to click i got it back to uk english - it has now connected to kies ok and is currently downloading the latest firmware - thanks partcularly to the last poster and to all others who helped - I will go through and thank you others too,
Point is now - once I have jelly bean can I get root access easily -without installing another custom rom - ahh well tomorrows problem

[Root Guide] Galaxy Tab 3 8.0 only with TWRP Recovery

Here is what I did to install TWRP for my Galaxy Tab 3 8.0, Root, and install Super user (compatible with the SM-T310, SM-T311 and SM-T315)
As best practice I always start with these prerequisites:
1. Full or near full charge on your new Galaxy Tab 3 8.0
2. OEM USB cable
3. Connect table to PC at least once to verify they can communicate
4. Use USB 2.0 port
5. Make sure your PC has an internet connection active
6. Make sure your table has access to a wireless internet connection
7. ** I used a Windows 7 PC ** (post 2 confirms Windows 8 works with this method)
Let’s get started (Total time less than 20 minutes, but hopefully more like 5 to 10 minutes)
1. Download ODIN 3.07 from (http://forum.xda-developers.com/attachment.php?attachmentid=1168421&d13411114315 )
a. Extract to C: root for easy navigation
2. Download Recovery TWRP from ( http://forum.xda-developers.com/showthread.php?t=2386098 )
a. I used release 3 from http://d-h.st/bQh which was TWRP v2.6.0.0
b. Place this in the directory from 1a
3. Power off your Galaxy Tab 3 8.0
4 With the tablet off you will now restart in "Download Mode" by holding the "HOME" button, "Volume Down" and "Power" all at the same time for about 3-5 seconds till you see the Warning!! screen
5. Toggle the "Volume Up" to enter download mode.
6. Start the ODIN.exe program you downloaded from step 1.
7. Connect your tablet to your PC
a. Drivers were automatically downloaded and installed on my Windows 7 PC (took a minute or two)
b. Make sure you have you table added in ODIN by looking at the ID:COM or in the Message window it will say Added!!
8. In ODIN Select “PDA” by putting a check in the box and then navigate to the .tar file from step 2
9. Now select “START”
10. In a few minutes or less your tablet will reboot automatically
11. Power off your tablet again and access the newly installed recovery
a. To access recovery press and hold volume up and power (release the power button once the Samsung Galaxy Tab 3 splash screen is visible continuing to hold the volume up)
b. Hold volume up until you see the standard teamwin recovery screen
12. Once in Team Win Recovery select Reboot from the menu on the bottom right if you are holding your tablet upright like a portrait. Select “System”
13. Hopefully you will be prompted to install ROOT like I was
a. If so, choose that you do and follow the rest of the on screen instruction upon boot
b. I chose the TWRP install method instead of the paly store and my tablet reboot after downloading a few files
c. I verified with root checker and I was successfully rooted
14. Should this not work you can manually install using ROOT_SGT3_8.0.zip file and flash via TWRP located here (http://www.mediafire.com/download/wjye1yssb5ksbfa/ROOT_SGT3_8.0.zip )
a. Copy ROOT_SGT3_8.0.zip to your tablet (placing on the root of the tablet storage or in the Download folder is easiest)
b. Access recovery press and hold volume up and power
c. Select "Install" from the Team Win recovery menu
d. Navigate to the .zip file and select it
e. Swipe to Confirm Flash after it is done select "Reboot" and reboot "System"
15. Verify that SuperSU is installed and run any root checker from the play store if needed
16. Update SuperSu from the play store and reboot using the TWRP method if needed.
17. Congratulations you should now be done!
You should now be Rooted and have a Custom Recovery. Additionally you are now ready for any Mods or ROMs and Kernels once released and after you do a backup in recovery
For thoses that have any issues try the followingthanks to Skiebs post #27)
When you get to the step to get into Odin, make sure you unchecked Auto Reboot. Hit the PDA and find your Twrp file like normal and hit Start. Wait until Odin is done loading the file, once it's done. Put it into recovery manually.
Once I did this instead of letting Odin reboot my system, it went right into twrp recovery, then I just downloaded the ROOT manually and loaded it through twrp.

Works great
Hi, i just did it. Works perfect in my tab 3 8.0 tm-310.
By the way, i used a laptop with windows 8 so it's works.
Thanks you very much for the guide.

I did all as per instructions with my t310 and i still don't have recovery installed? what am i doing wrong?

My Galaxy Tab 3 8" (SM-T311) Has Successfully Rooted!
Finally, I decided to root my Samsung Galaxy Tab 3 8 Inch (3G Version) with this root method. I use desktop PC with Windows 8 Professional in it. Everything is running smoothly as described in this tutorial. Thank's very much for this helpful tutorial.
Happy rooting and be the device ours!

It Worked!
It didn't work at the first go.
In the second round, I disabled 'Auto-Reboot' in ODIN and flashed TWRP. Post flashing, I powered down the tab manually.
To launch TWRP, I pressed the Power + VolUp keys and let go of the Power button upon appearance of Samsung Logo (but kept a tight press on the VolUp) key.
I was not auto-prompted to root the tab. Had to installed the ZIP package manually.
Following Root, "Device Status" shows "Custom".
Is there anyway to to now unroot the tab and restore it to Factory Shipping status? Will definitely need it before a warranty claim.

Noob question - where is the USB debugging selection? Instructions don't say anything about it but, from phone rooting experience, I was automatically looking for it to be sure it was on in preparation, can't find it. Thank you!

To enable Development Mode, open Settings, About Device, click 7 times on Build Number.

Just curious
If I am rooting this device, is the stock ROM that everyone is referring to the same ROM that shipped with the device (including Samsung bloatware, etc.) or is it stock Android 4.2 which can offer multi-user profiles? Noob question sorry, just eagerly waiting to get something closer to stock Android. Ideally, CM 10.3

No its the same rom shipped with the device.. but the good news is you can remove all the unwanted softwares after rooting.. CM 10.3 is not supported for our tablet.. hopefully it might be released in sometime

Thanks! that's what i figured. it's not so much the bloatware as it is multi-user. i bought it (stupidly) thinking that if it had 4.2, there would be multi-user support. it's annoying logging in and out of things and i don't feel like shelling out for another tablet. guess i'll just be patient. thanks again!

Thanks
Worked perfectly with windows vista machine. You made my day. Thanks

Help with TWRP
Hey I have odin up and running and got the tablet hooked up to it and the drivers installed and everything, but the when is extracted the .tar file it kept coming up as a IMG file and when i tried to use it with odin it didn't recognize it....can anyone help? What am I doing wrong?

Do not extract it. Odin uses .tar and .tar.md5 files.

installed ok with win 8 x64 thx very much

FAILED
I mistakenly disconnected usb cable thinking ODIN finished loading TWRP. It didn't complete TWRP installation. I can still access TWRP but can't obtain root either way. Tried rebooting pc, tablet, reinstalling TWRP. Get this:
<ID:0/016> Added!!
<ID:0/016> Odin v.3 engine (ID:16)..
<ID:0/016> File analysis..
<ID:0/016> SetupConnection..
<ID:0/016> Complete(Write) operation failed.
<OSM> All threads completed. (succeed 0 / failed 1)
i think i need to manually remove all TWRP files and start over again but not sure what to look for. Would installing an older version fix it? Should i try CWM and will it overwrite my broken TWRP?

Worked Great...
Thanks

Very nice guide. It worked flawlessly. Thank you.

Greetings;
Have you solved your problem?
If not, tell me what Android version are you running on your device?
i.e: Gingerbread; Ice Cream Sandwich; Jelly Bean or KitKat.
Assuming you are running stock firmware i believe that either your brother flashed a wrong CF-Root for your device or used an application that could not root your device properly.
Either ways don't worry since your device can enter both Download and Recovery modes, it means that you can debug it.
[Rooting]
The best way to root this device is by flashing CF-Root file.
By flashing this file (CF-Root) you will be installing:
- ClockWork Mod Recovery
- Script that will root (automatically) your device.
- ext4 application. (do some research to know what ext4 is and how it os often used)
Small note: Since you will be rooted you will be able to overclock or underclock your device as well increase your device performance and battery duration.
Just PM me or do some research if you need some info regarding these configuration and settings.
[Fixing your issue]
Download Universal CF-Root here:
http://forum.xda-developers.com/showthread.php?t=1351056
Read the instructions before proceeding.
Now boot your device under Download Mode.
To do so:
Unplug USB Cable, Power Off your device and press the following key combination:
Vol.Down + Menu/Home Button + Power Button.
Release when the device enters download mode.
Now open Odin.
Under [PDA] load the CF Root File you've downloaded.
(Do NOT change any options inside odin if you dont know what they are for. Or you may get your device useless).
Put down your device so movement is done into the USB Cable (just to prevent bad flashing when you have low quality USB Cable).
Press Start and let the operation to complete.
Odin will display a message saying: "Pass" highlighted with Green.
Check if your device restarts (it may not restart yet)
If your device boots properly backup your data and follow the next step. If it doesnt boot properly follow to the next step.
Voot your device into recovery mode.
To do so: Power off your device and make sure it is not charging or connected to USB cable.
Then press and hold the following key combination:
Vol. Up + Menu/Home Button + Power Button.
Release after the Boot Logo is shown and you will enter recovery mode.
Now you will perform a Factory Reset.
Inside CWM select by the following order:
- Wipe Dalvik Cache
- Clean Cache
- Factory Reset
Note that Dalvik Cache is not shown at the main menu.
I dont remember the location exactly but if im not mistaken you can find it under "Advanced".
After you perform these 3 options the device shall reboot properly.
(it may take a little bit longer this time. Just be patient).
Since i dont know what was done to your device, there is still a chance that your device wont boot.
Either ways please let me / us (at XDA) know if it worked for you.

Greetings;
Have you solved your problem?
If not, tell me what Android version are you running on your device?
i.e: Gingerbread; Ice Cream Sandwich; Jelly Bean or KitKat.
Assuming you are running stock firmware i believe that either your brother flashed a wrong CF-Root for your device or used an application that could not root your device properly.
Either ways don't worry since your device can enter both Download and Recovery modes, it means that you can debug it.
[Rooting]
The best way to root this device is by flashing CF-Root file.
By flashing this file (CF-Root) you will be installing:
- ClockWork Mod Recovery
- Script that will root (automatically) your device.
- ext4 application. (do some research to know what ext4 is and how it os often used)
Small note: Since you will be rooted you will be able to overclock or underclock your device as well increase your device performance and battery duration.
Just PM me or do some research if you need some info regarding these configuration and settings.
[Fixing your issue]
Download Universal CF-Root here:
http://forum.xda-developers.com/showthread.php?t=1351056
Read the instructions before proceeding.
Now boot your device under Download Mode.
To do so:
Unplug USB Cable, Power Off your device and press the following key combination:
Vol.Down + Menu/Home Button + Power Button.
Release when the device enters download mode.
Now open Odin.
Under [PDA] load the CF Root File you've downloaded.
(Do NOT change any options inside odin if you dont know what they are for. Or you may get your device useless).
Put down your device so movement is done into the USB Cable (just to prevent bad flashing when you have low quality USB Cable).
Press Start and let the operation to complete.
Odin will display a message saying: "Pass" highlighted with Green.
Check if your device restarts (it may not restart yet)
If your device boots properly backup your data and follow the next step. If it doesnt boot properly follow to the next step.
Voot your device into recovery mode.
To do so: Power off your device and make sure it is not charging or connected to USB cable.
Then press and hold the following key combination:
Vol. Up + Menu/Home Button + Power Button.
Release after the Boot Logo is shown and you will enter recovery mode.
Now you will perform a Factory Reset.
Inside CWM select by the following order:
- Wipe Dalvik Cache
- Clean Cache
- Factory Reset
Note that Dalvik Cache is not shown at the main menu.
I dont remember the location exactly but if im not mistaken you can find it under "Advanced".
After you perform these 3 options the device shall reboot properly.
(it may take a little bit longer this time. Just be patient).
Since i dont know what was done to your device, there is still a chance that your device wont boot.
Either ways please let me / us (at XDA) know if it worked for you.
It is important (at least for me as a quality standard) that you are able to repair your device.
Best Regards
Please press thank button if this helped you. Since this will keep me motivated to continue helping.

Thanks for your reply. Frankly speaking I don't remember which Android version I was using may be Gingerbread (Is this important)
I downloaded "bagaria-09.GT-I9003_PDA.tar" from the link given by you and following procedure that you have mentioned. After odin says "Pass" I switched off my mobile and started in Recover mode it took around 15-20 mins to show recovery option. after this performed
- Wipe Dalvik Cache
- Clean Cache
- Factory Reset
and then Reboot. As you said phone is stucked on boot image for more than 15 mins then an loop on "SAMSUNG" logo after more 15 mins phone is showing "kernel panic upload mode"
Can you help me further?

Hello amoghs;
Again sorry for answering after so long; I'm not so often at XDA Lately.
Yes.
1st: Try Remove the Battery, then Put it Back and Try Again.
If this doens't Work:
1) Turn your Device Off and Press:
Vol. UP + Home Button + Power (To Enter CWM / Your Recovery Mode)
2) Select: "Factory Reset"
Let me know how it worked for you.
Note:
- After Flashing a ROM it is Normal that your Device Takes a little Longer to Boot on the "1st" time.
- Phone Stuck on Boot Logo and Looping: Boot Issues (Either Requires to Remove and Place Back the Battery; or Re-Flash the ROM or Stock Rom in a Difficult Stage).
Notes:
- After a Flash Perform a Factory Reset (To Clean Up Old Stuff).
- If you Experience: "Kernel Panic":
a) Remove Battery and Place it Back - (Works on Most Cases)
b) Flash your ROM again and DO NOT Instal Custom Kernel (May be Wrong Kernel or Bad/Incompatible Kernel Programming)
c) Phone Restarts by Himself: Reflash ROM, Try MinFreeManager or Similar APK (Application). Try "Optimal" Settings. (I dont recall the Presets names - But you can Safely test them - Even if device gets stuck. You can always revert to previous state).
d) Any Hard-to-Solve Issues: Just do a "Clean Flash" of STOCK Gingerbread (Check Sammobile Website - Invalid Download Links Just send email to Support Requesting the File)
or Flash "DDLF2 2.3.6 (Also Gingerbread). But always try Stock 1st to remove most issues, and only then Flash your Desired ROM.
Also if you haven't fixed the Boot Issue already: Do note that you can recover your device Boot.
NOT Dead Yet!
Please do let me know if you solved your Boot problem.
Best Regards;

ROOT SM-T210R SIMPLE and Easy, 8gb, White

Okay so I've been at it for days and i mean like months.... when I first bought my 8 gb white Samsung galaxy tab 3 Kernel 3.4.5, android 4.1.2, model JZ054K.T210RUEAMK1 and all i have been running into is problems, like jittery display issues, or flickering display, I tried every method but none has worked but i finally found one and got it all working and running, First of all i would like to thank gr8nole for this method, and all who have helped him. So first let me explain the most easiest explanation for dummies like me, or noobs
Just and example video for visual learners http://www.youtube.com/watch?v=XolmtyvS3Yk&feature=youtu.be, but you want to click on the files i suggested on the bottom lol not what he has on his screen xD
Must Have: KIES, make sure you have fully updated rom from samsung themself which can be found on kies when you plug it in and update firmware, which your android should be on 4.1.2 and version because that's what i have
1. First lets Get all the files we need, First go download SM-T210.CWM.6.0.4.5.recovery.tar.zip at his xda post http://forum.xda-developers.com/showthread.php?t=2433853, after you have download that you will a friend name odin, which can be found here http://forum.xda-developers.com/showthread.php?t=2189539 (With odin you only want to use v3.07) and nothing else , Last but not least you want this file from gr8ole android-armeabi-universal-root-signed.zip and save that to your sd card or ext while click on usb debugging or w.e you wanna store in on tablet
so you should have odin 3.07
T210.CWM.6.0.4.5.recovery.tar.zip
android-armeabi-universal-root-signed.zip
2. Use the same method as g8nole and minor adjustments
Instructions:
1. Download ODIN on your computer (just do a google search to find it...version 3.07 will work fine). http://forum.xda-developers.com/show....php?t=2189539
2. Power off the device.
3. Restart in "Download Mode" by holding the "HOME" button, "Volume Down" and "Power" all at the same time (for about 5 seconds).
4. Hit the "Volume Up" to enter download mode.
5. Start the ODIN exe program using admin rights which means right click run as admin. I recommend un-checking Auto Reboot. DO NOT CHECK RE-PARTITION LEAVE UNCHECKED YOU BEEN WARNED (which it already should be). See notes about ODIN below.
6. Connect the device via USB to your computer. Verify the device shows as "Added" in the Message box. If it doesn't show then you need the Samsung USB drivers (just install KIES to get them) which can be found here http://www.samsung.com/us/kies/.
7. Select "PDA" then choose the T210.CWM.6.0.4.5.recovery.tar.zip.
8. Hit "START"
9. Wait for device to restart. Which means wait til odin says OKAY in the white box and the Picture ask you to reset, When the download icon under download updates is full bar, and odin says reset!, just unplug it. then restart by holding the power button down, with vol up, and home, once the samsung picture shows, only hold the up vol button, recovery mode should now be on. Select install zip, and locate the android-armeabi-universal-root-signed.zip)navigate with the up down volume button and power button to select) file, whichever you placed in sd, or exsd,
10. When all is done reboot device, then it will update your android once you turn it on, Now the anoying part, It will be rooted but what google play won't connect?, easy fix , first lets just update all the binaries since its already rooted in supersu app,
Google Store Fix, now first you have to delete your some things, your apps wont dissapear or nothing as long as you dont uinstall them, go to settings<application manager<all<google play store<clear data/cache w.e<force stop<uninstall updates<it will then ask you it will be factory installed<yes, next step, delete your gmail account if you haven't done so, now go to your time settings (Date and Time) and change it to recent date whichever today is , then open play store and it will ask you to sign in again, blah blah google needs sign up and it should be up and running
ALL DONE, remember this is for people who have run into flicker display problems, which is caused by kernal issue with our model, but with stock rom itself we can universally root it through odin with just that simple method which took me like 3 mins lol to do
Grats guys! you have root and cwm now who doesn't want that enjoy and thanks to developers hard work! and my ambition!

this worked for my SM-T210 also. Thanks heaps for this how-to!

Ok my device is already rooted but I would like to install CWM Recovery on it. So I can make a backup. Or does anyone have the stock kernel for it

But you can also use Odin 3.09.
I'm portant is that you flash always the newest CWM / TWRP or PhilzTouch Version about the new updater scripts.

Your best option is to get CWM sknce it will be your original backup instead of a Rom created from another device.

SM-T2105?
Hello,
I came here beacause of a shorcut link given by @gr8nole and another member (I forgot sorry).
But my English must be to bad, i read and re-read, still don't find the answer...
I have the G Tab 3 kids model, SM-T2105.
@bierma32 says: "Important is that you flash always the newest CWM / TWRP or PhilzTouch Version"
Could you tell me wich one is the best, CMW or TWRP, plz? (the last I can find for T210 is CMW-6.0.4.9 and/or TWRP-2.8.2.0)
More important, do you know where I can find the zip of a rooted stock rom, including that 'kids' stuff? (SM-T2105). Or will I not loose the stock rom? Is there no wipe? Sorry, I don't understand.
I want to root, because of lack of space, and the rest.. but I don't want to loose that..
And the most important, "last but not least", I could not find the zip " android-armeabi-universal-root-signed.zip", so can you help me please, putting a mirror or so? Or could it work only with flashing a SuperSU zip? Not so easy, right?
As you maybe can read, I am a newbie in Android rooting. Or is there another way to do?
Thanks for reply.

[Q] GT-P3100 is restarting by itself and not rooting when tried

hello all,
I am having a samsung galaxy tab 2 gt-p3100 and it is out of warranty now. It was working fine till the day when my cousin installed a game of almost 2 GB size (fifa, also i dont know whether the problem is due to game or not). after the game was launched tab showed restarting issues. It is restarting again and again by itself even when I am not using it. I decided to factory reset it but it didn't worked. I tried hard reset also and again it was not working. All apps data were present there even after reset, nothing was changed.
I did some research on android forums and XDA and found that installing custom ROM can solve this issue else I have to get my motherboard replaced.
I started with rooting and installing CWM recovery on my device. I did the process using a video tutorial and used the files mentioned in it from XDA. the files name is :
"P3100_CWM_RECOVERY-6.0.1.3_SUPERSU-0.96_BUSYBOX-1.20.2.tar.md5"
My odin message box displays below messages. :
............
<ID:0/007> SetupConnection..
<ID:0/007> Initialzation..
<ID:0/007> Get PIT for mapping..
<ID:0/007> Firmware update start..

<ID:0/007> RES OK !!
<ID:0/007> Removed!!
<ID:0/007> Remain Port .... 0
<OSM> All threads completed. (succeed 1 / failed 0)
(Before showing PASS messages. odin showed me RESET message and it was only when tab restarted it showed me PASS)
This shows that process is completed and my device should be rooted. But when I checked there was not Superuser installed and no custom recovery was seen when recovery mode was started.
Also, tab when started shows error messages like "gapps stopped working", "gmail stopped working". In short, all the google apps were displaying these kind of messages.
Please help!!! and suggest me how should I proceed to try custom ROM.

Have you checked root access using any app? If no then do check it.
---------- Post added at 03:24 PM ---------- Previous post was at 03:23 PM ----------
And can you boot into recovery? Volume up+ power button?

i tried booting the device into recovery mode using volume up and power button but itt shows android recovery mode.
Also, i tried installing the application to test for root but tab won't allow the installation to finish. It restarts in between so cant check using apps.

File which i mentioned in above description is for rooting as well as cwm recovery (it was shown in the video as such) so it should complete both processes. But for me it seems none is completed.

Yes i tried that option too but the installatiin was failing in between.
For once, i took my tab to samsung service centers too, they too tried to flash rom using odin (i was able to see there working on pc) but there process was also giving the same result - fail.
I am having a doubt, should my device be rooted to install cwm recovery or this recovery is required to root the device as i am planning to again perform these processes individually using other tutorials individual for both.
I hope this helps.

Maybe you have got the famous trim bug,I think you should use the superuser zip method to root your device,the one without recovery included,
Then try flashing the recovery,

I have already tried to flash stock rom from sammobile and as i have already mentioned, same process was also tried by engineer at samsung service center and the process failed. In all, that process is almost tried on this tab for 5-6 times but with same result.
I also noticed one thing that this tab is stuck at one particular state. No mattwr what i do with it, it comes back to same home screen and without any changes. For example, if i start my tab and uninstall some application and change the view of home screen and then if the tab restarts, it will be back to previous state i.e. no apps unonstalled and home sceen will also b back to previous state. All changes are reverted back.

I have the same problem as yours. Tried to flash the stock rom, wiped the device thru the android recovery, every thing fails. If there is anyone with the solution, let me know.

I have the same problem with a Samsung Galaxy Tab 2 10.1 P5100.

I have the exact same problem to P5100. No solution yet, still reading everywhere.
