Unlocking 32 inch Wallboard Outcome Health - Android Q&A, Help & Troubleshooting

All, I have found a solution to get this P-WAL-107-ELC-02 unlocked and usable!
Original post:
I acquired a used Outcome Health (Contextmedia) Wallboard. There have been other posts previously about unlocking the 10 and 13inch tablets, but the steps and procedures used did not work with this wallboard.
The model number is P-WAL-107-ELC-02, and is similar to the item found here: https:// fccid.io/ 2AI6X-PWALELC
It is running on Android 4.4.4
I can open the "secret" configuration menu built into the app, but all the functions are password protected. I've had no success accessing the default android settings menu either. If you close the app, it launches again immediately, and the status bar seems to be locked down so that it can't be expanded.
EDIT: I've tried using a USB keyboard, and used the settings hotkey but no luck with this either. Using the home button pushes a message at the bottom of the screen "Override Launch." I also tried generic passwords in the various menus, but nothing has worked so far.
Any suggestions or experience with these items is greatly appreciated, thank you!

Rebooting into safe mode and removing contextmedia applications:
With the help of information in this thread: https://forum.xda-developers.com/android/help/android-4-4-4-context-media-10-tablet-t3670769 I got it working.
With the wallboard connected to the pc, I restarted the device and repeatedly pressed the power button until it finished booting and it started in safe mode! I was able to open the android settings, uninstall the contextmedia app and the zygote app, access dev options and enable debugging.
Connected to the PC and in debugging mode run the following to remove the synop and the remainder of the contextmedia applications.
adb reboot root //Worked in my case, confirmed root access.
adb shell
[email protected]:/ $ su //Root permissions in shell
[email protected]:/ # rm data/dalvik-cache/[email protected]@[email protected]
[email protected]:/ # rm data/dalvik-cache/[email protected]@[email protected]
[email protected]:/ # rm -r data/data/com.contextmediainc.system.synop
After that, it should let you simply uninstall or disable everything else.
With that removed, you should be able to install any compatible launcher (I used nova launcher at the time of writing this) with the adb install commands.
Flashing TWRP recovery and installing open Gapps:
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.
Flash your recovery image via adb shell on android
JANUARY 16, 2017
//edit: You need a rooted device for this kind of flashing
Hi, ever wondered about how you can flash a recovery.img via adb shell?
A lot of posts suggest flashing it via fastboot. Well my ****ty Samsung phone is not detected by fastboot. Then there is the option to install a dubious binary file which is called flash_image.. thank u internet!
Well damn I have the recover.img whats so hard to use dd and flash it with a single shell command? For those who don't know much about linux commands here we go;
Enable your USB debugging bridge in switch via adb to the terminal:
./adb shell
Then you should be able to find your recovery partion with:
DEV=$(ls /dev/block/platform/*/by-name/recovery); echo $DEV
that should output something like this:
/dev/block/platform/7824900.sdhci/by-name/recovery
If this is the case you only have to put the recovery.img on your sd-card or the internal storage and you are one command from flashing:
dd of=$DEV if=/external_sd/recovery.img
Thats it! No binaries you have to install. No ****ty fastboot udev rules :S
You can enter into your new recovery system with:
./adb reboot recovery

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.
Install SuperSu if you want to maintain permanent root on the device!

No suggestions, but what a cool find. I'm surprised that hospitals use Android smart TVs! Or is it a giant tablet?

It seems more like a giant tablet. I saved it from the dumpster hoping it could be turned into a nice web surfing machine for the garage.

How often do I click the power button when it is booting, to get into safe mode? It just keeps going back to the home screen for me. Also, which USB did you have connected to the PC while doing this?

---

I am having the same issue

---

Any further update or progress on this from anyone? This would be perfect for a garage (or wherever) media center.

---

Any idea where I can find the recovery file? I tried to obtain one via TWRP and no luck.
I was able to install nova laucher and delete the files in data using adb shell. I'm just stuck at the recovery image part.

Freak-tab .de website is down. Can someone please send me the image recovery file? Thanks in advance.

I'm able to get mine to the Recovery System but I cant run adb shell as I get exec '/system/bin/sh' which is no root. But I can't get into Safe Mode. I have the 32" Wallboard too but mine is ELC-01. What power button combo did you use to get into Safe Mode?
Plug in power and then just mash the power button? When do you stop mashing it?
Mash it as you plug in power and keep mashing?
Plug in power as you hold the power button down?
Stop mashing when it flickers or the screen is white?

Can’t get in to the settings.

Wallboard
There are some typos in the original post commands. I wasn't having any luck with the "rm" commands to remove "zygote" and "sysop" apps, so I used the "ls" and "cd" commands to see what the file names were.
Removing the second file should be "[email protected]:/ # rm data/dalvik-cache/[email protected]@[email protected]" , the third should be "[email protected]:/ # rm -r data/data/com.contextmediainc.system.sysop"
When you type the command "DEV=$(ls /dev/block/platform/*/by-name/recovery); echo $DEV" you'll get an output, type that output into the next command. ex: dd of="output of previous command".
If you just drop the TWRP onto the USB mass storage drive that appears when you connect the tablet, it will be in "/sdcard" folder. The final command will be something like: dd of="output of previous command" if=/sdcard/RK32.img. If you don't have root access it will tell you "permission denied", so make sure you use the command "su" after "adb shell".
Lastly, I accidentally found that when I performed a factory reset via TWRP recovery menu that the Home button started working. It may also work via the settings menu, but I didn't try it that way.
Anyway, hats off to OP for posting this as it gives use to these massive android tablets.

Kinda stuck...
Hey Slaysher62. I'm kinda stuck. Was wondering if you could help me out. I have a few of these due to our hospital just not needing them anymore and telling me I could either keep them or throw them away. I've tried for weeks to replicate your success but I feel like I'm missing a few steps. If you could Message me or something that'd be great.
Thanks,

Help with recovery
Recently acquired 3 of these 32-inch screens at first I wasn't able to get into safe mode but I deleted everything off the sd card and restarted the screen after that spamming the power button worked and I was able to get the app uninstalled and Nova launcher installed but what I'm having an issue with is getting TWRP to install also I noticed mine isn't a RK3288 its a RK3188
I've tried to flash all the TWRP RK3188 recoveries I could find but none of them work just puts the screen into a boot loop until removing power and restarting

any update from android 4.4
was anyone able to get any operating system installed on this besides andriod4.4? trying to decide if I am going to just use the screen and install a new mini board to install android 10 or chrome os
---------- Post added at 07:41 PM ---------- Previous post was at 07:36 PM ----------
to get to the secret menu . power on "tablet", wait till the program is running . you will see a logo close to the bottom right hand corner. keep pressing it until the menu pops up. to get into the actual settings I can't remember what it was called but I should be something like device admin or such on the right hand sign. click it. it will ask for password ( cat10dog ) from there you should be able to follow the instructions above

Uit232b-u03
Thought I'd chime in; I have one of these wallboards, model # UIT232B-U03, nominally equipped with an RK3188. Here's what I've found:
Misc. Device Info
RIL Ver: KitKat ril-rk29-dataonly v3.3.00
Build No.: Z05-outform-32-B4.21-20160324
Build Fingerprint: rockchip/rk3188/rk3188:4.4.4/KTU8Q/eng.root.20151208.162319.eng/test-keys
Board / Chipset: rk30sdk / RK30board
As you might notice from the Build Fingerprint, this model appears to be running an engineering build of Outcome/ContextMedia's KitKat ROM; this screen was pulled from a working clinic, but USB debugging was already enabled and connecting via adb shell automatically dumps you into a root shell. There's nothing more you need to do to gain that access.
The device info (courtesy of Droid Info) references three different RK chips in a few places: RIL Ver. (rk29); board & chipset (rk30); and everywhere else (rk3188, specifically). I don't know what to make of that. Maybe something to do with it being an engineer build? Could be an engineering sample board, too -- I need to check for that info.
Personalization
As mentioned, it looks like this unit (and maybe other UIT2xx-xxx revisions) appears to come pre-rooted with USB debugging already enabled. There's no need to authorize any given machine on the tablet when connecting over ADB for the first time, either. If you still want/need to access the system settings, three-finger-tap on the application logo in the bottom-right of the screen (tapping multiple times will just cause a credits list to pop up). The password to leave the application for the Android system settings is cat10dog, as has been noted elsewhere.
Before I loaded anything new, I went ahead and factory reset it to see what it looked like. Upon doing so, the only system application was Zygote -- it looks like it's a modified version which is serving as the "launcher" for this tablet, and which forcibly reloads the application whenever it is closed for whatever reason. From factory reset, it will launch into a first-time setup screen, where it looks like you can configure the application and get connected to wifi/ethernet and download the remaining system apps (this is my impression; I didn't go through with it, but I imagine the application will want to verify a license or something). Uninstalling the modified Zygote seems to not kill the first-time setup screen (makes sense -- it's meant to stay resident and likely has everything it needs loaded into RAM at the time), but you can install Nova Launcher 5.3 (last version to support KitKat 4.4.4) and then Zygote fully disappears and you won't get bothered about setup anymore. (I have no idea what happens if you remove Zygote and then don't install a launcher. You can probably still connect over ADB, but I've never seen a launcher-less Android.) Other apps can be installed at this time, too.
As noted elsewhere, the Home and Recents soft buttons still do not work. I'm not 100% sure, but I think that's something stuffed in the ROM itself and may not be configurable (maybe through the commandline?). But, you can just use the Back button to go back to the home page at any point.
I have not had any success installing TWRP: It turns out, despite the chip being labeled in all ways as an RK3188, it is in fact a lower-specced RK3188T (1.4Ghz top speed). Every version of TWRP for the RK3188 I've tried has resulted either in a bootloop (unplug from power and plug back in to return to system), or a black screen, or the TWRP splash screen but which never progresses beyond that step. (This reminds me, I need to check on the black screen instances to see if the recovery executable is running at all, and what happens when I try to manually start it.)
On the off-chance anyone has a TWRP build for the RK3188T for me to try, I'd definitely appreciate it! Or indeed any ARMv7-based build, if I'm just going to be blindly loading recoveries to see what happens. (If anyone has any advice for debugging the recovery loading process, I'm rather a noob at this and could use any information about where to look for logging info, or to make it output a log at all if it doesn't by default.)
OH, and uh... if anyone has a stock version of the recovery partition, could you send it to me? I didn't back it up before writing over it...
Other than not getting to install TWRP and get all experimental with ROMs, it is usable in its current state as an old-but-servicable, pre-rooted-for-your-convenience-no-supersu-required, massive Android tablet. Too bad Pocket Camp requires Android 5 since a few builds ago...
Edits for grammar, spelling, extra info.

device configuration and also just to clarify what he meant was tap on that flower looking logo repeatedly until you get the secret device configuration then on top right corner theres 3 lines select network settings and it should ask for a password which is cat10dog

And now I'm stuck
If anyone could give me direction/etc to get past where I'm at, I'd appreciate it.
I bought one of these bad boys from an auction and thankfully found this post and started the task of customizing it. I got to the point to where I deleted the apps listed, all through adb reboot recovery (used Generic RK32 with SDcard).
However, on reboot, it didn't go into recovery and had the Context Health splash to a nature backdrop and an Error: Wallboard not installed message. USB debug wasn't persistent, and trying everything that worked previously, I can't seem to get into Safe Mode, and I haven't found any other ways to get into Settings.
I did find the "reset" hole on back, which otherwise functions as a hardware 'Volume Up', but have yet to find any [Boot to Recover] methods involving only Volume Up and Power that work.
Any ideas of things to try?
Thank you
Update 1: Still no luck overall, but somewhat of progress, I hope: Plugging in the DC automatically boots up everything. If I hold down the hardware volume up/reset while adding power AND have USB plugged in, I get a listing in Device Manager; however, the screen stays black. Otherwise, as far as getting my PC to notice it, this is the only means to do it. There is no connection when powered on normally, rather I plug in USB before or after providing power. Also, spamming the power button while booting in order to get into Safe Mode had worked initially. Now doing it causing a freeze on the second or third splash screen refresh.

So I have recently acquired a bunch (50+) of these 32" screens. They were pre-rooted as @dwkindig had mentioned. I was able to remove all of the Context media apps and unlock the functionality as a basic android tablet pretty quickly. Threw Nova launcher on it and they work great. Has anyone had success in getting anything above Android 4.4 on these? I have a ton and can pull any files that would be of help to do some digging here, so please let me know. I would love to at least get Lollipop on these so that Android Webview could be upgraded and I could use the Wallpanel app for dashboard use on these. Any suggestions or help I can offer?
