Sure, all you need to do is use the T210 root method, recoveries and what not. I have both my kid tabs rooted with cwm touch recovery on them using the T210 model.

Have you used the the cwm/twrp and root signed.zip from gr8nole thread Root Recovery for SM-T210/210R for the kids tab?
What kind of language support your kids ROM? I search a ROM which supported German.

Yes I used the cwm that gr8nole posted. There are no custom roms for the kids version yet but if you need german support I do believe I saw a german official firmware you can flash thru odin when I was downloading the US version.

Thanks, I really just wanted to root it. Custom recovery is pointless as I don't plan on any custom roms. Just wanna remove bloat. I was thinking custom kernel too, but I'm not sure whats out there that works with the kids tab. Suggestions?

Hi,
I have a kids tab 3 (SM-T2105) and a normal tab 3 (SM-T210R)...basically i purchased the normal one before the kids one and i want to add the kids mode app on the normal one...if i create a nandroid back up of the kids tab can i load that image to the normal tab?
i'm new to this scene and just trying to weigh my options...i tried the "mybackup pro" option and that didn't work...any feedback would be greatly appreciated. thanks

SM-T2105 Galaxy Tab Kids - Corrupted USB Connection
Monday, 13 October, 2014 04:44:05 PM - SM-T2105 Galaxy Tab Kids - Corrupted USB Connection
---------------------------------------------------------------------------------------
Hi all.
I've spent almost the full 2 days looking for solution of this but to no avail.
My tablet is using 4.1.2 Jelly Bean.
I owned the SM-T2105 Galaxy Tab Kids rooted. Then suddenly I was thinking to move all my apps to SD card. Trying and trying, finally I realized that I need to make separate partitions on the SD card first.
So one of the solutions I found on the internet suggested to make that partition using the PC. Then I am interested to connect my device as mass storage instead of the default MTP connection. So I found this - https://play.google.com/store/apps/details?id=com.mohammadag.samsungusbmassstorageenabler&hl=en.
Without reading any further, I quickly installed it and turn on the mass storage function. But to no avail. My PC can't recognized the tablet anymore since then. Immediately, I quickly uninstalled that app and looking for another app. But still the same problem.
So finally I am stucked with "connected as an installer" whenever I connect the tablet to my PC. And the worst thing that, I cannot change it back to MTP/Camera transfer mode i.e. my tablet would immediately reboot! I was totally intensed since then. After trying and trying, I still cannot find the solution.
Then I thought a firmware upgrade will do. So i install the latest firmware for SM-T2105 - T2105ZHAND2 from here - http://www.sammobile.com/firmwares/download/32189/T2105ZHAND2_T2105ZZHAND2_TGY.zip/. I also rooted it again then.
But still the problem persist. I also end up using the ADB terminal from my PC to issue the
Code:
su
setprop persist.sys.usb.config mtp,adb
reboot
But still the same problem. My device would restart immediately after issuing the command.
I have also found this code below somewhere but the issue is I cannot find that /sys/devices/platform/msm_hsusb/gadget/lun0/ path on the tablet:
Code:
Mass Storage Mode
---------------------------------------------------------------------------------------
setprop persist.sys.usb.config mass_storage,adb
echo /dev/block/vold/179:33 > /sys/devices/platform/msm_hsusb/gadget/lun0/file
Return to MTP
---------------------------------------------------------------------------------------
#!/system/bin/sh
echo "" > /sys/devices/platform/msm_hsusb/gadget/lun0/file vold
setprop persist.sys.usb.config mtp,adb
The nearest folder that I could find is /sys/class/android_usb/android0/f_mass_storage but no lun folder inside. Only nluns file is sound
So I am really stressed with this. Can someone here please help me out?
Besides of all those issues, turning off the Developer Options/USB Debugging would also make it restart on the spot.
Factory reset would be my last choice.
I was expecting something like system files update or something. Is it possible?
Thank you very much.

[Q] Samsung Galaxy Tab Kids SM-T2105 Problem

Hi there.
I am new in the forum. Thanks ind advance for any help you can provide me.
Here's the issue:
We just bought the new "Kids" Version. It came with 2 accounts, the normal mode and the kids mode. The kids mode was accessible through a "Kids mode" icon in the normal mode.
I really don't know what my wife did, but she erased the "kids mode" icon and that account is not accessible anymore. Still, I can search for the kids apps and they still show up.
I got two different error messages. An "error 210" and the "Unfortunately the Setup launcher has stopped" (or similar. I don't have the tab here with me)
I thought my only choice here was to download the firmware it came with it, which is T2105UEAMK3-XAR, and re-install it. But KIES won't let me install it, since it displays the "Your firmware is up to date" message. And Samsung doesn't have an official firmware download anywhere. I also talked to an online Samsung representative, who directed me to perform a hard reset. Still, back to factory settings, the "kids mode" icon didn't appear. So he told me to schedule a service. But my daughter won't get any happier if I send out her beloved toy for a week or two.
This is my first venture (or issue) with an Android device. I have found a seemingly endless numbers of video tutorials and the likes, but still, I don't want to mess up with it.
Any help would be greatly appreciated -specially by my daughter
Thank you.

[Q] Developer options.

Hi guys,
I am having a nightmare finding the developer options on my tab S 8.4 (SM-T705). I have enabled it by pressing build number 7 times and had the pop up stating that it is enabled, yet I cannot for the life of me find the menu. Does anybody have any idea where I am going wrong?
Thanks in advance

general tab... before the about menu... try reboot your device

Thanks for your reply
It's really weird because it is not there. That is where it is found on my phone and my old tab 3 but it's nowhere to be seen on the Tab S.
I have rebooted and it's still not there. I have also tried to enable again by pressing build number 7 times but I get a pop up saying "no need, developer mode has already been enabled." I even factory reset to see if that would sort it but still the same thing.
hmmm.. back to the drawing board i reckon..

Were you able to solve this? im having the same problems

It's a firmware base issue.
Update manually using Odin T705XXUX1ANJ3 (Russian CSC) and "hey presto".

SM-T320 - can't find OEM Unlock switch in Developer Options

I feel like this should be obvious, but I'm unable to find the OEM Unlock switch under Developer Options on a Galaxy Tab Pro 8.4, SM-T320.
I must have found it once before because I rooted and installed Android 7.1 on the same model (different tablet) last fall. But for whatever reason, it's eluding me on this one. Apparently, on Samsung devices, that switch is hidden; to reveal it, you need to turn off automatic downloads and auto date and time, restart, open Developer Options, and so on, but there is no switch for automatic date and time anywhere on this menu, which is unlike any other I've seen on an Android device.
I have USB Debugging checked, but the tablet won't root, and it seems that unlocking the bootloader is the sticking point. And it's driving me nuts. As noted, I must have done this with the other tablet, but I can't find that switch on that tablet either -- and it would look different anyway, since it's not the tablet's stock Android.
Please help? Any suggestions will be appreciated.

I found another web page on which it simply says to check USB Debugging. I had done this before, but unchecked and rechecked it to be sure. Then I tried to root once more, using the file:
CF-Auto-Root-mondrianwifi-mondrianwifixx-smt320.tar
...which worked on my other tablet last fall and again tonight. Still, the tablet isn't rooted. I cannot figure out what I'm missing.

Well, a few more hours and attempts later, the tablet still wasn't rooting, so I started the tablet in recovery mode and reset it to factory before trying it again. This time, it worked! Clearly, there was something (an app, perhaps?) that was getting in the way. I still don't know where that OEM Unlock switch is, but I no longer care.

From feeble memory, I recall having one tablet (only one, an SM-T520) that would only do what I wanted by first flashing it back to stock. From there, everything was fine. I have another SM-T520 and a couple of SM-T320's, any of which couldn't care less what I do to them.

I guess that's the fail-safe position. Since I was installing a newer build anyway, it didn't matter. It just seemed odd since the other SM-T320 rooted just fine without that extra step. I wish I'd thought of it sooner, but that's water under the bridge.
BTW, if those other tablets work and you're interested in selling one of them, drop me a PM. And if not, no worries; I just thought I'd ask.

Do you have a link as to where I can download twrp flash recovery for tab pro 8.4? It seems like it needs a tar.md5 file.
Thank you!

Look here: https://eu.dl.twrp.me/mondrianwifi/
3.4.0-0 available as tar file.

Trying to get a clean install on a crippled SM-T540 (Galaxy Tab Active Pro).

Edit 3: USIC, after further investigation, has confirmed the tablet was actually one lost in shipment and compensated for by insurance, the sale was legitimate (not a stolen device) and they unenrolled it from KNOX before I could ask if they would do so. So, overall a satisfactory outcome, even if the tech part of me wanted to find a way to defeat a technical challenge.
EDIT 2: The device may not be stolen after all, seller has given a plausible explanation. Withholding further judgement until more information comes in.
EDIT: I was originally thinking of 'USIC' as a subsystem of Android or KNOX. A user on Reddit suggested I reach out to the company USIC and see if the tablet was stolen from them. I did. It was. Will be getting the tablet back into their hands and pursuing a refund from the eBay seller. Will leave this post up in case anyone has a use for the technical rabbit hole I went down.
Backstory: Found a good deal on a new Galaxy Tab Active Pro from an IT liquidator company on eBay, it was listed as locked and price reduced because of that. I thought along the lines of 'hardware access is total access' and figured I would be able to wipe / reset it.
Device arrived today, the crippleware (MDM or administration software actually, but I'm feeling ornery at it) installed is Soti Mobicontrol. I can boot into the OS but a bunch of stuff is disabled. First I initiated a factory reset from Settings - it resets and during setup lists "This tablet is protected by Knox Cloud Service. To continue setup, connect to a Wi-Fi or mobile network." From there it states "Your admin can monitor and manage settings".... a bunch of stuff ending with "USIC will manage and monitor this device using the following app: MobiControl" with the only option being 'Accept & continue'.
Tried another factory reset through the boot menu (hold down vol down and power to reboot followed by hold down vol up) - same result.
Found and downloaded the same version firmware the tablet currently has: SM-T540_XAR_T540XXU2BTG5_fac.zip where XAR appears to be the US/Canada region code and T540XXU2BTG5 is the exact version of firmware the tablet currently has installed (verified by going to 'Software information' in settings).
Downloaded latest version of Odin (3.13), booted the tablet into the correct mode and flashed clean firmware (just the AP firmware) to the device. Went through first install sequence to no change in behavior, still installs Soti Mobicontrol as a device admin.
I've looked into maybe getting TWRP installed (so I can delete KNOX from TWRP file browser perhaps as demonstrated here:
) but as far as I can tell there isn't a build for this version of the tablet - closest I can get is for the SM-T547 XDA forum post on it here: https://forum.xda-developers.com/t/...alaxy-tab-active-pro-10-1-snapdragon.4284347/. Also not sure how I would get it installed since I can't enter dev options in the tablet (tapping on Build number, even in safe mode, results in a popup: Action not allowed This action is disabled by MobiControl. Contact your organization's administrator to learn more.)
I've found someone on YouTube (
) who removed the software just by intentionally entering a wrong password until a factory reset tripped - but I am already able to use the factory reset option and the software comes back. I'm thinking Soti Mobicontrol and the KNOX service are separate issues and in this person's example he was only dealing with Soti and not KNOX Enrollment.
Next I found this gentleman on Youtube:
who specifically mentions using the 'Nand erase' option in Odin along with flashing all files in the stock firmware to remove management software. Tried that, no luck. Same as each install I get the message 'Updating... Updating Knox Enrollment Service... X%' after being required to connect to wifi to continue setup with the 'Skip' option greyed out.
So, that's where I am right now with it, and I refuse to give up. Ideas?

@studentoflife don't know this device but might be a chance to flash the multiple part stock ROM you can get via Samfirm_reborn.

I am unfamiliar with Samfirm_reborn. What is this project? I can't seem to find much in the way of descriptive notes.
Edit: apologies, did some googling and now know what Samfirm_reborn is. I'm pretty sure I've already flashed all parts of the stock ROM - downloaded the T540XXU2BTG5 version firmware and flashed the BL, AP and CSC images. No CP image given this version of the device does not have a cellular modem.
Hm. I suddenly wonder what will happen if I reflash with the earliest version instead of the current one. I know I don't want to update it to the latest firmware in case that applies some security patch that can't be downgraded and locks out some workaround I haven't found yet, but downgrading... maybe.

I have a similar tablet with mobicontrol. I can't unlock OEM so all the methods of flashing new firmware I tried, failed. Have you had any luck since your last post?
