[Android Q&A, Help & Troubleshooting] slaysher62:
All, I have found a solution to get this P-WAL-107-ELC-02 unlocked and usable!

Original post:

Disclaimer:

This is a collection of the methods that worked successfully in my case. I am assuming anyone using this has an understanding of the use of ADB and shell commands. If not, please do your research to better understand the use of the command line, otherwise you may cause more damage then actual repair. Perform the actions followed at your own risk.

Rebooting into safe mode and removing contextmedia applications:

With the help of information in this thread: https://xdaforums.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

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.

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.

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.

[Android Q&A, Help & Troubleshooting] ttiimmmmyy:
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?

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.

---------- Post added at 01:11 AM ---------- Previous post was at 12:20 AM ----------

Freak-tab .de website is down. Can someone please send me the image recovery file? Thanks in advance.
[Android Q&A, Help & Troubleshooting] HRLQN:
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?
[Android Q&A, Help & Troubleshooting] mizaza:
Can’t get in to the settings.

Can’t get into settings. Tried the power button variations, with and without mini usb plugged in to the pc.
[Android Q&A, Help & Troubleshooting] ArCanSawDAve:
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 "root@rk3288:/ # rm data/dalvik-cache/data@app@comcontextmediaincsystem.sysop-2.apk@classes.dex" , the third should be "root@rk3288:/ # 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.

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.

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
[Android Q&A, Help & Troubleshooting] n4zty:
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
[Android Q&A, Help & Troubleshooting] DaveDischord:
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.
[Android Q&A, Help & Troubleshooting] pedwards3x:
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?

Whenever I am connected to WiFi for around 5 minutes or more and then disconnect from the WiFi, my phone will not reconnect to mobile data, it'll show an exclamation mark next to mobile signal to show it's not connected. I'll have to restart my phone to get it connected to mobile data again.

Happened to me too. Usually it's fixed by restoring the stock modem files via mfastboot or twrp. It's quite a known issue on the lineage 15(.1) ROMs as well. Temme if you need more help with the restore operation.

Hi guys,

Sorry for the noob question; I just got my OP7Pro last night in Shenzhen and it didn't come with a play store (i totally forgot about that)

Is there any way for me to install it? I downloaded an APK but it's having a hard time connecting.

Hope you guys can help me out.

Thanks!
[OnePlus 7 Pro Questions & Answers] wr3zzz:
If you are not a Chinese mainland resident you are better off just swap out the H2OS and replace it with O2OS. AFAIK the unlocked version phones are all identical. O2OS has the complete Google suite.

If you are not comfortable doing it yourself there are plenty of shops in Shenzhen/Hong Kong that can do it for you for a fee. Oneplus does not void your warranty for swapping OS.

Back on T-Mobile now thank's to this amazing Community. Some steps to help others.

Step 1- Download the file in the original post, create a folder somewhere you know where it is and extract the downloaded files to that folder

Step 2-Turn off your OP7 Pro

Step 3-Open the folder you created and right click on MsMDownloadTool V4.0.88.exe and select run as administrator, Once open uncheck sha256 check.

Step 4-Plug the Original USB cable that came with your phone into the phone.

Step-5-Hold the Power/Volume up/Volume down button until you see Connected in MsMDownloadTool, the instant you see Connected press start. You only have 5 seconds before it's too late so be quick.

Step-6 Once you see "Download Complete" in green in the Status of Communication box in MsMDownloadTool the phone will automatically reboot and you should have the TMobile splash screen and be able to set the phone up through the set up Wizard.

That's it you are done.

I was hoping someone could clarify or help me on this... I have a tmobile lgv40. When I got it last October I was able to get my OneDrive account added so that I could access it via the built in file manager and gallery apps. I've noticed, and it has been like this for a while, OneDrive is no longer available in my file manager or gallery apps. I've attempted over and over again to add it but it will not stay. My wife has the same phone and it is doing the same thing.

Is this a bug? Or did one of the security patch downloads change something? We are on the Feb 2019 patch and uptodate.

FWIW, I got into my MSA privacy settings and deleted lg phone from the apps permission area. When attempting to sign back in after this clearing I had to give lg phone access permissions again. I hoped doing this would work but it did not.
