[Android Q&A, Help & Troubleshooting] Mr-Ace:
Sideload should work, but I'm not 100% sure.

If you can get the tablet to sideload mode, you should be able to flash a custom ROM(or GAPPS if you get the Media Health stuff off).
[Android Q&A, Help & Troubleshooting] cdietric:
The problem is that in sideload it doesn't allow me to uninstall the Media Health crap. It says waiting on tablet and then the tablet just doesn't do anything.
[Android Q&A, Help & Troubleshooting] Mr-Ace:
It might not be working because USB debugging is not turned on. Try connecting over WiFi. You'll have to get the ip address of the tablet first though. Try "adb shell netcfg".

Afterwards, follow this guide to connect over WiFi.
[Android Q&A, Help & Troubleshooting] cdietric:
So I feel like an idiot now. I managed to turn on USB debugging finally. in the developer options at the top you can switch it from off to on which allows you to make changes.
[Android Q&A, Help & Troubleshooting] Mr-Ace:
That's ok. At least you figured it out now instead of later!
[Android Q&A, Help & Troubleshooting] cdietric:
Unfortunately I still can't remove their install but I did manage to install Nova Launcher over top of it and also installed a custom recovery. I will try to install the stock kitkat 4.4.4 rom I have now.
[Android Q&A, Help & Troubleshooting] Mr-Ace:
That's great! Which recovery did you flash? I wasn't able to do that myself.

Hopefully other people can figure theirs out as well.
[Android Q&A, Help & Troubleshooting] cdietric:
i installed recovery reboot but it doesn't seem to actually do anything. I'm going to see if I can find a way to get clockworkmod on here. do you know if they have the apk for rom manager?
[Android Q&A, Help & Troubleshooting] Mr-Ace:
I think I read somewhere that they removed the recovery from the tablets. The Rom Manager apk can be found here.
[Android Q&A, Help & Troubleshooting] cdietric:
Ok, but when i install the rom manager what do I do from their. anytime I try to reboot into the custom recovery I just get either a blank screen or it goes to the android recovery already on the system.
[Android Q&A, Help & Troubleshooting] Mr-Ace:
Well, the Rom Manager app requires root, so you're going to need to root the tablet, either with a .zip or an app. The .zip is more likely to work because rooting apps usually have a way to detect what device you're on. Because these tablets are so rare they likely have no support through those apps. I'd use a SuperSu .zip and sideload via ADB. Just make sure the .zip you get is compatible with Android 4.4.4.

EDIT: I don't know if the Rom Manager app is specialized per device as well, so it might not work either.
[Android Q&A, Help & Troubleshooting] cdietric:
So the Rom Manager did have root access, but from the looks of it the only company with a compatible root version for this tablet is the original manufacture, context media. They did use TWRP for their recovery from the looks of it but I can't find a TWRP recovery that will flash and work. I have reached out to the manufacturer to see if I can get some details in order to wipe their crap off entirely so that I can then load a new, clean version of the OS on. I will keep you all updated if i hear anything.
[Android Q&A, Help & Troubleshooting] Mr-Ace:
All right. Am awaiting an update!
[Android Q&A, Help & Troubleshooting] slaysher62:
If the tables are the setup the same way as the wall board, you can use adb and shell to remove the synop and contextmedia stuff. Synop is the one that would remove damn near anything I installed on it.

Connected to the PC and in debugging mode run the following:

adb reboot root //Worked in my case, confirmed root access.

adb shell

shell@rk3288:/ $ su //Root permissions in shell

root@rk3288:/ # rm data/dalvik-cache/system@priv-app@zygote_standalone.apk@classes.dex

root@rk3288:/ # rm data/dalvik-cache/data@app@com.contextmediainc.system.synop-2.apk@classes.dex

root@rk3288:/ # rm -r data/data/com.contextmediainc.system.synop

After that, it should let you simply uninstall or disable everything else.

I'm still have problems with the Google Play services and Gapps crashing. If I can sort that out, ill give you an update.
[Android Q&A, Help & Troubleshooting] slaysher62:
Last night I finally got a working TWRP recovery using the TWRP_2.8.7.0_RK32.img using the method show here https://blog.matt.wf/flash-your-recovery-image-via-adb-shell-on-android/

Generic RK32 with SDcard - http://www.freak-tab.de/abdul_pt/TWRP/Generic/TWRP_2.8.7.0_RK32_SDcard.img

Generic RK32 with Unified Storage - http://www.freak-tab.de/abdul_pt/TWRP/Generic/TWRP_2.8.7.0_RK32_DATAMEDIA.img

Turns out the manufacture is Rockchip and the series is an rk3288.

With that, I could flash the gapps from the recovery and now the play store and services are working seamlessly. With the exception of the home and recent buttons not doing anything, this one is completely usable now.
[Android Q&A, Help & Troubleshooting] Mr-Ace:
Wow, this is great! It's nice that anyone can get their tablet working. I only wish my tablet wasn't zonked so I could do this myself. Nice job! :good:

Edit: Are you going to try to install a custom ROM? I'm curious to see if it would let you.
[Android Q&A, Help & Troubleshooting] slaysher62:
I can't guarantee it will work on the 10 and 13 inch tablets, since I'm working with the 32 inch wallboard, but I suspect for the most part it will work though. I did a more complete write up here: https://xdaforums.com/android/help/unlocking-32-inch-wallboard-outcome-t3936524

For now, I've got permanent root access and all the basics, so i'm going to let it be for now, and I may explorer a custom rom later.
[Android Q&A, Help & Troubleshooting] gr8brg:
Hi. Just got the tablet and can't seem to get into the menu. Only can get into the "Configuration screen" and not always...must try for 5 minutes until I finally able to get into that. What do I do now?
[Android Q&A, Help & Troubleshooting] gr8brg:
Oh, it's running 4.4.4 and model number: UIT3138-U01, 13" screen. After hours and hours of trying, can't get into the "settings" menu, only rarely into "configuration screen"
[Android Q&A, Help & Troubleshooting] slaysher62:
You should be able to get into it from safe mode. Try bringing up the power menu, and then press and hold power off until the safe mode dialog pops up. From there, try some of the suggestions listed in this thread. Once in safe mode you should be able to active USB debugging and run commands though ADB and shell as root
[Android Q&A, Help & Troubleshooting] gr8brg:
Pressing power button on the back of the unit itself or the "reboot now" soft button in the middle of the screen that pops up when I touch the hard power button on the back? How do I bring up the "power menu"?

1. When I press and hold the hard white power button on the back, the menu shows up with following options: "Sleet for 15 minutes, sleep for 1 hour, Shutdown device for the day and "Reboot now" that's all.

2. Holding "reboot now" button does exactly that - no safe mode.

3. Just pressing and holding white power button on the back just shuts down and restarts the device into the contextmedia loop again.

4. Pressing volume down and power at the same time brings up green andorid man with "no command" note. From there, pressing power and volume up, does reboot again into NORMAL LOOP.

I just can't access safe mode or setup. That's why I'm asking. Thanks

Thanks
[Android Q&A, Help & Troubleshooting] slaysher62:
I ment the power off from the soft key menu. Sorry I didn't make that more clear. Glad you figured it out though :good:

Most likely named differently for the 13" tablets. Since your in safe mode now, can you uninstall the apps from the settings menu? In my case I could uninstall everything but the synop app. If you have the synop app is imported to remove that too, or it will actively uninstall most software pushed by adb.

Also im so sorry, I see I made a typo when i posted that. it should read:

root@rk3288:/ # rm data/dalvik-cache/data@app@com.contextmediainc.system.synop-2.apk@classes.dex

root@rk3288:/ # rm -r data/data/com.contextmediainc.system.synop
[Android Q&A, Help & Troubleshooting] gr8brg:
Ok, so I figured out my file names "1" and not "2". Now, I was able to install Nova Launcher. HOWEVER, after using adb to remove all of theose ContextMedia junk files and restarting the tablet, it says: "upgrading android" and it it installs those files back again! I am still able to see and use Nova. BUT, I can't seem to remove Synop app as it seems to be protected by security settings. When I try it says: "Can't uninstall because this package is an active device administrator". It takes me to "Manage Device Administrators" window where under Synop it says "Grant Contextmedia the permissions to modify and enforce device settings". It's checked off and greyed out so I can't uncheck it. Any ideas?

Alright. Making progress. After the step above I decided to use settings to "restore to factory specs". That worked! I was able to remove all Contextmedia files including annoying Sysop app. Home button works. But I just can't install / flash recovery with TWRP. The instructions earlier do not make sense and it does not happen for me. Can you walk me through in a clearer way?
[Android Q&A, Help & Troubleshooting] cdietric:
Since I put it in the internal storage I would probably have to change external_sd to internal_storage, correct? Also I'm not seeing the same app you guys are having an issue with. the only context media crap this tablet has on it is com.contextmediainc.system.zygote. Do you know what commands I would have to run first in order to remove it as the system sends back an access denied message even with root.
[Android Q&A, Help & Troubleshooting] slaysher62:
Yes

Try su mount -o rw,remount /system

Then run the remove command again
[Android Q&A, Help & Troubleshooting] cdietric:
cmd output "/system/bin/sh: su: not found"
[Android Q&A, Help & Troubleshooting] Rortiz2:
Seems that the tablet it's no pre-rooted. Try rooting it with kingroot. (Since is kit-kat it will root it)

Then:

adb shell

su

mount -o rw,remount /system

rm data/dalvik-cache/data@app@com.contextmediainc.system.synop-2.apk@classes.dex

rm -r data/data/com.contextmediainc.system.synop

Once you have root shell you can try flashing TWRP with dd. But you need to know recovery partition num.
[Android Q&A, Help & Troubleshooting] cdietric:
Well I may have screwed up the stock recovery, I can't get the tablet to root, I tried to basically start from scratch but every time I go to boot into recovery it just gets stuck now. I think I may be stuck with just using nova launcher on this device...Any ideas?
[Android Q&A, Help & Troubleshooting] Rortiz2:
What? Stock recovery doesn't matters now...

Just install the attatched apk as you installed nova launcher.
[Android Q&A, Help & Troubleshooting] cdietric:
You think that'll make a difference over doing it from the computer?
[Android Q&A, Help & Troubleshooting] Rortiz2:
Well in computer you can do adb install XXXX.apk

It's almost the same. Only install the app open it, and send screenshot of what appears.
[Android Q&A, Help & Troubleshooting] cdietric:
It gives me the same error as when I ran KingRoot from my computer, unable to get root, submit request? That's why I was trying to get into the recovery so that I could wipe the tablet back to factory and try again without having installed everything else already.
[Android Q&A, Help & Troubleshooting] Rortiz2:
Thanks for the feedback. So try RootGenius or KingoRoot. There a lot of programs that may work with this device.
[Android Q&A, Help & Troubleshooting] cdietric:
RootGenius failed as well, I tried that one before KingRoot. I will give kingoroot a try.

Edit: KingoRoot "Root Failed error code: 0x1BA84B" only solution it provides in app is to try the PC version.
[Android Q&A, Help & Troubleshooting] Rortiz2:
Try PC version. And If it doesn't still working, try rebooting recovery with ADB:

adb reboot recovery
[Android Q&A, Help & Troubleshooting] cdietric:
So the PC version worked, I will attempt to install the custom recovery and update you guys with what happens.
[Android Q&A, Help & Troubleshooting] Rortiz2:
Wait wait. You have ROOT but you need to know what are you doing.

Please, can you make a backup of stock recovery.img and stock boot.img?
[Android Q&A, Help & Troubleshooting] cdietric:
I have already done so. Besides, even if I hadn't I have 5 more to pull these off of if necessary. Now I am trying to do the "flash" from the adb shell using the steps located here: https://blog.matt.wf/flash-your-recovery-image-via-adb-shell-on-android/ the only problem being i get the error cannot open for read: no such file or directory. I have confirmed that the image is there though.
[Android Q&A, Help & Troubleshooting] gr8brg:
I have 2 stupid questions (I think).

1. First, how do you get TWRP onto the internal storage from adb? what command since it's not install.

2. I can't seem to find the proper TWRP flash for my tablet. Among numerous manufacturers there's no Rockchip (3188). Also, what version will I need for my 13 inch tablet? Don't want to screw up flashing of recovery.
[Android Q&A, Help & Troubleshooting] cdietric:
There are actually a few other discussions on the forum that people have links to working recoveries for these devices, a quick google search did it for me. Just try something along the lines of rk3188 twrp recovery. As for getting the recovery onto the tablet, I turned off USB debugging and turned on usb storage. I copied the recovery over to the tablet from there.
[Android Q&A, Help & Troubleshooting] gr8brg:
Thanks. Did the search like you said. No working links. All lead to spam / installer sites. No working img can be found....bummer :(
[Android Q&A, Help & Troubleshooting] gr8brg:
Ok, now I'm at the same step and it says: no such file or directory. I enabled USB switching and placed recovery file on both SD card and internal storage, but adb can't seem to find it... any ideas?
[Android Q&A, Help & Troubleshooting] Xer0s:
For the first question.

You can use adb push command which is adb push (directory of your file and file name) (tablet destination directory and file name)

Example

adb push c:\yourfile.img /sdcard/yourfile.img

The way I did it was...

Once you have usb debugging enabled, plug it into your computer and mount the tablets usb storage in android.

Download the APKs of a root app like kingoroot and a launcher program. (I used smart launcher 5 because nova would not work) Copy the APK to the base directory. (I named them something like kr.apk and sl5.apk for easy use.)

Unmount the usb storage, as it won't be accessible in adb while mounted.

open the command line on your computer and change directory to your adb directory.

type

adb shell

then

pm install /sdcard/kr.apk (or whatever your apk is called)

then

pm install /sdcard/sl5.apk (or whatever your apk is called)

This should install the root program and custom launcher. Using the custom launcher, open your root program and root that thing!

From here you can go back to your command line and type

adb shell (if your not still in there)

then

SU (this will give you superuser access in the adb shell and should change the $ to #)

To install a custom recovery image from here, download your .img file, mount the usb storage on your tablet, copy over the .img file to you base directory, unmount the usb storage on your tablet. (I named mine twrp.img for easy use)

From here you can go back to your command line and type

adb shell (if your not still in there)

then

SU (this will give you superuser access in the adb shell and should change the $ to #)

Then type

DEV=$(ls /dev/block/platform/eccm/by-name/recovery)

then

dd of=$DEV if=/sdcard/twrp.img

CUSTOM RECOVERY IMAGE INSTALLED!

Question 2 (and the crappy part)

I have found 2 recovery images that "work" for the RK3188 version of these tablets. (both the 32" and the 13.3") Every other rk3188 recovery.img makes them black screen when booted into recovery, or in the case of the rk32xx version mentioned earlier in this post, it glitches out, then reboots into android.

The first is a generic TWRP recovery image. The problem is, upon booting into recovery mode, it sits at the TEAMWIN screen for 10?ish minutes before it gets to the interface. Once in, you see various mounting errors, and nothing works. Can't flash zips, wipe anything, or mount anything. Upon extracting recovery from recovery.img, and then looking at it with notepad++, it appears the directories are not pointing where they should. (something like /dev/block/platform/something other than emmc/ect...)

The Second is a generic CWM recovery image. It boots immediately into CWM recovery, but it suffers from the exact same problem.

I hope this helps someone. If anyone finds a compatible recovery.img for the rk3188 please let me know!
[Android Q&A, Help & Troubleshooting] k46tank:
I came across a couple of the 13" version of this tablet that also uses the rk3188 chipset and, thanks to the previous posts in this thread, have managed to get them at least minimally usable. I was able to root them with the PC version of Kingroot then was able to push Nova Launcher 5 onto them. I was not able to delete the files defined on the post above involving the big wall board that has the rk3288 chipset. I am assuming they are named slightly different on these tablets. If anyone has located these files, please post the paths to them so I can try to delete them.

I would really like to install a custom recovery like TWRP or CWM but, like everyone else, I haven't found a version of anything that works correctly. My ultimate goal would be to install a stock version of KitKat, or newer, or a custom ROM so this would become a fully functional tablet.

Thank you to everyone that has posted previously as you have been a big help. Please continue to update this thread with your progress. I'm sure someone will finally figure it out.
[Android Q&A, Help & Troubleshooting] johngypsy:
Did anyone ever find a compatible TWRP (or other) recovery image for these devices? I have the same 13.3" tablet and I'm at the same point here now. I have my own launcher installed and can run apps installed via ADB, but I'd like to get GApps working. That generally requires a recovery image like TWRP or a lot of manual work. Anyone have any luck getting GApps on this -- either manually or via a working TWRP/recovery image?
[Android Q&A, Help & Troubleshooting] WootyB:
Psst, I just scored a ton of these 32" and 13" devices, if it asks for an admin password, ours was "cat10dog".

If you cant figure out how to get into Android, triple tap the letter "o" in the logo "Context Media". They are now "Outcome Health" so try the "o" in that if your device is updated, otherwise try a combination of triple clicking one of the letters in the logo.

Been a while since I've messed with any of this but I too came across one of these tablets. I have the 13.3" variant.

4.4.4

Base unknown

Kernel 3.0.36+

I ended up factory resetting and of course getting the endless looping of the context media crap. Side loaded nova launcher which is nice as I can now actually silence the context media stuff and access the app drawer (even though nothing I install works). Also, I'm assuming since this is so old, at this point theres no recovery to download?
[Android Q&A, Help & Troubleshooting] ryanmar89:
I don't believe there is a recovery available but there could be one out there somewhere. If you ever manage to find one though, please let us know.
[Android Q&A, Help & Troubleshooting] hinds73:
Any idea what would be the reason for the baseband version showing "unknown"? If I triple tap it comes up with a box asking for a password. Tried the cat10dog but just said error after closing the dialog box.
[Android Q&A, Help & Troubleshooting] ryanmar89:
That I don't know. I saw that too the last time I was messing around with them and tried a bunch of passwords and none of them worked.
[Android Q&A, Help & Troubleshooting] hinds73:
Were you able to get the context media stuff removed from the system or was it kinda figured out that it was built into the existing rom and would simply reinstall on reboot?

Currently trying to figure out if I can make it use the sd I have installed. It recognizes it but can't seem to get it to read or write to sd. Also want to get a working version of playstore and gapps installed.
[Android Q&A, Help & Troubleshooting] ryanmar89:
I had rooted it to remove the zygote app but the branding still shows on boot. I don't remember the rooting software off hand at the moment. I'll have to take a look when I get a chance. I never got the playstore to work properly though.
[Android Q&A, Help & Troubleshooting] hinds73:
I wonder if I could've gotten the zygote app off if I had tried rooting first. I wiped it before I rooted. I used Kingroot to do mine.

Would like to get my hands on one of the 32" models (RK3288). There's a company here in town that has them installed. Waiting patiently for them to ask me to get rid of them.
