My Samsung galaxy s2's screen reciently got smashed, nothing comes up but I believe the rest of the system works. Now when I connect to my computer it just charges. So I was wondering if there is any way to retrieve my contacts, internet favorites, pictures, and memos without replacing the screen.
Thanks
i cant do too much research at the moment, but I have an idea.
Assuming that you have clockwork recovery installed:
I think there is a way to mount the file system using clockwork recovery.
*You should try looking up the key combo to get into the recovery screen in boot
*Then look for specific instuctions on how to mount the file system.
*Since clockwork recovery is entirley controlled with harware keys you should be able to navigate without seeing what you are doing
*(just look at the instructions and press the appropriate keys, the appropriate amount of times to get to where you need to be)
Its a shot in the dark (bu-dum-chi) but I think it might be your best bet.
This should point you in the right direction:
http://forum.xda-developers.com/wiki/ClockworkMod_Recovery
If not, there may be a way to remove the internal storage and put it into a simmilar device and get the data that way. But I cant really help with that.
assuming it does turn on, turn it on and plug it to your pc, then use adb (android debug bridge) which comes with the android sdk to pull files out of your phone.
as for the contacts you can pull the sqlite db file:
http://www.droidxforums.com/forum/droid-x-rescue-squad/30987-acquire-contacts-via-adb.html
you can also parse them directly on phone with the sqlite3 command while in adb shell.
Is there any feedback on this.

I've just used Samsung Kies and was able to retrieve data, now I am looking for a way to format the internal memory.
Howdy folks,
Yesterday, I was the proud owner of a sleek little TCT.Alcatel OneTouch A554C, formally know as a Virgin Mobile Venture running Android version 2.3.5.
It was successfully and surprisingly easy to root by utilizing 2 cool little apps, Ministro and Poot-Debug.
After root, I subsequently downloaded some root tools (eg., Titanium Backup Pro, Superuser Elite, System App Uninstaller).
That was last week.
Yesterday, I got a bit cocky. I needed to clear up some internal memory so I used "System App Uninstaller" to uninstall a few apps. If I remember correctly, the apps were as follows: Google Maps, Google Maps Street View, Calculator, Digital Clock, Setup Wizard, Android Live Wallpaper, Live Wallpaper Picker, Magic Smoke Wallpaper, Music Visualization Wallpaper, and the TouchPal Keyboard French and Spanish Language Packs.
So far so good, right? However, I believe I may have snarfed-up when I uninstalled the Setup Wizard. But I'll get to that in a minute.
Now with Titanium Backup, I moved some apps to the sd card. Included was the stock launcher, Smart Launcher Pro, SPB Shell, AVG Anti-Virus, and Superuser Elite. Then I rebooted through Titanium Backup and I haven't viewed any pornographic material since!
After reboot, the phone got stuck on the final boot animation frame. I panicked, pulled the battery, booted into recovery then rebooted a 2nd time.
This time it booted to the pull-down lock screen. I unlocked and seen:
"Sorry! The application com.android.setup wizard has stopped unexpectedly. Please try again." Along with a "Force Close" option. I forced closed and the screen went black with the exception of the status bar. The phone is still on but otherwise...nada.
When I press the power button, same thing happens: pull-down lock screen, screen goes black. Or sometimes, it will turn on and boot loop.
Major panic time!!! I booted into recovery again and performed a factory reset to no avail.
Another clue to note: I can connect & access the sd card via usb to desktop.
Also, I did have the good sense to backup all apps, system and user, through ES File Explorer and stored them both on sd card and in the cloud via Yandex Disk prior to this bricking fiasco. Now, what do I do with them? I now realize it was possibly a mistake moving all 3 launchers to the sd card. How do I get the stock launcher back to the phone?
Or, should I:
1- Attempt a base rom reinstall or
2- Attempt a custom rom install or
3- Use it solely as a time piece/mass storage device or
4- Throw it very hard and very ******* far away from me!?
I realize this is an obscure little cheap phone but it's the only one I have. Any valid feedback would be greatly appreciated.
You can go to the Play Store on any browser and choose a launcher to install. Or if you have USB Debugging on, you can side load an launcher apk. Or if you install a custom recovery, you can install another rom or sideload an apk there. Or you can flash the original firmware via SP Flash Tool.
Lots of options and none of them need to be throwing it against the wall.

Hmmm...Ok, thanks. Dig your username, by the way.
First thing is, install from play store would be possible if I had data service or if I was able to enable wi-fi. I only have calling & texting service on this phone and as for wi-fi, I can't enable it due to the problem of not being able to access the settings menu. All I have when it does boot, and it only fully boots when it is connected to a PC, is the pull-down lockscreen displaying time, date, status bar and the original wallpaper. Pull it down and the screen goes black with status bar still displayed along with time & battery level.
Secondly, USB debugging was enabled prior to all of this but I panicked & performed a factory reset. Don't think it's still on.
And lastly, is installing either a custom recovery, (which, to be frank, I'm just not that savvy) another rom or flashing original firmware even possible without a PC? Because I only have access to a PC without administrative privileges so therefore...no installing exe's without a password. Maybe this program lab will allow me, quite possibly not.
Hell, would I even still have root after a reset/data wipe?
Thanks, anyway, Esoteric Chaos

You can go to ANY browser - even on the PC and log into your account and hit Install and it will send the command to your phone to install it. Pretty nifty. But you did say you factory reset, so that isn't actually going to work. Sorry.
The rest of the stuff would require a PC, though I don't think admin rights are needed, so there's that...
If you don't have your phone logged into Google or USB Debugging enabled, you're kind of stuck without a PC.

Well, on these PCs it certainly does. I thought I was on track yesterday and tried to install a copy of Odin that I found. Can't install without a frigging admin pass.
Someone else just suggested I try a stock rom flash. Might as well, right? Happen to know where I could find a good reliable copy? That also happens to be free?
Not sure why you were trying to use Odin for a non Samsung phone...?
The stock rom flash would only be possible via PC or if you had a custom recovery installed.
Here's what you would need to do for the Virgin Mobile Venture:
Download CWM: http://www.sendspace.com/file/4gt04i
Download adb/fastboot: http://forum.xda-developers.com/showthread.php?t=2317790
Download rom: http://goo.im/devs/LeslieAnn/Venture/Stock_Venture.zip - Put on SD card.
Drivers: http://pdanet.co/bin/PdaNetA4150.exe (this program is for USB tethering and installs the adb drivers for your phone as well as many others)
The CWM img will need to be in the folder you unzipped for adb/fastboot. You'll need to boot to fastboot mode by powering on with while holding Volume Up.
Open a terminal prompt and change directories to your adb/fastboot folder. Then run this command:
fastboot flash recovery nameofrecovery.img - fill in the nameofrecovery with whatever the CWM file name is.
(if this doesn't work - make sure that your PC is reading the phone correctly by using the command: fastboot devices . If you don't get anything back, make sure you check the Device Manager for errors. If you have them, try reinstalling the drivers and rebooting the PC)
Then pop the battery out and then reboot to recovery via powering on while holding volume down. Once there, you should be able to do a factory reset and then install the stock rom zip. The volume keys should scroll through selections and the Enter key for accept, or Power if that doesn't work. Not really sure about this particular phone.)
Actually, you might just be able to use adb to install a launcher apk once you have CWM installed. Might be a little easier.
launcher apk must be in adb folder then while in CWM:
adb install nameoflauncher.apk
Note: You can rename zips and apks to be easier to type the commands.

Yeah, me either. I was all over the place yesterday grasping at anything. So Odin is only for Samsungs, huh? Guess I can delete the exe file from my sd.
Right then. I'm about to proceed with your advice. Cross your fingers and toes.

Wait, what? Please excuse my ignorance, but am I missing something. ADB didn't come in a zip. It's an installer. I think you may have to dumb this down a bit more, mate.

If you can't run the exe file, then let me know, and I'll just upload a zip / folder with the necessary files. You do not need admin access to run the adb commands.

That would be really cool, actually. But check this out:
I talked someone into allowing me to utilize his laptop. I installed ADB, moved the Launcher APK to the folder suggested, ran the commands but the command prompter responded with "waiting for device" and progressed no further. Could it be a driver issue? I was under the impression that if the PC recognizes your device (which it did) then a new driver install was not necessary.
Dude was real cool about it even though I ran his battery down quite significantly and didn't even accomplish anything.
So, if I had the ADB files then I could just copy them to...say the PC desktop and run the command prompter from there? If so, then yes please upload and I'll just try it that route rather than rely on someone's personal PC. Know what i mean?
I do appreciate all of this. I'm getting quite the education here. If you ever get married, let me know and I'll come and dance as my favor to you.:good:
Peace...I'll return tomorrow.
What mode were you in when trying to install? The laptop had the most up to date drivers? You checked the Device Manager to make sure there was no yellow exclamation mark next to the phone? It's not unheard of for the PC to recognize in one mode, but not load the correct drivers in another, as there are different drivers for the phone depending on if it is booted, in recovery, or download mode or whatever they call it for that phone. Just make sure to get the PDAnet drivers installed and reboot. That should do the trick.
Everything else you should need will be in here:

I was in Recovery and I was also attempting to install the just the Launcher versus the entire ROM. And I was also feeling a tad bit rushed, cause dude was right there informing me of his battery status. "Well, it's down to 30%." Then 2 mins later.."Ok, looks like it just fell to 25%."
Haha...so yeah, with him pressuring me, I spaced on checking the device manager. This desktop that I'm on today seems to be cool. Just checked the manager & it informs me that my device is 'working properly'.
Off to give it another bloody joust, mate. Wish me luck...
Can you fully explain how to do this

Hi there, i've been trying to make some changes to my build.prop (mainly enable miracast...can't believe they would disable it!) and i've had a rather challenging time.
I am now stuck on how to pull the actual build.prop...when i enter the command i get a long list of ADB definitions but no file - at least not that i could find. I tried a few times, including directing the file to be saved on an empty drive in case i could not see it.
I have unlocked my boatloader and installed TWRP. Mounted the system then gone back and entered the commands in ADB....and i don't seem to be having any success. Any help would be appreciated.
thanks

Why not just edit it within the built in editors in most file explorers? I use Solid Explorer and it allows me to edit at will within the app itself, no pushing or pulling. Of course I back up my current one before doing anything to it

i'm not rooted...and i've read that you don't get OTA updates...and it's happened to me more than once that i have an issue with the phone, and i can't get service because it's rooted...
and i guess i thought it was too much trouble to get rooted, make the changes, and then unroot...but i could be wrong at this point?!
You won't get OTA with twrp either. You need stock recovery.
so i bit the bullet and rooted my phone...i was able to get the build.prop editor to work (at first i did not have busybox which it seems helps apps to realize you have root). So now when i go to unable Casting, i can turn it on from the top right of the cast screen, and my tv appears. I can select it and it starts to sync up...then the mircosoft display adapter shows that it's also trying to sync...and then it times out it seems. I've checked it with my tablet and my wife's phone...both work.
any suggestions?
I understand Miracast no longer works in Nougat. I'm still on MM with my 6P and it works, but if you're on 7, you may have lost that feature.
What about WUGS toolkit? Do you need to re rooted for that...ifnot thats what I always use to edit the prop. So much easier as it has most edits you'll make and you just choose.
you never needed to root i edit build.prop like this all the time
1. boot to twrp recovery
2. go to mounts and select system
3. adb pull /system/build.prop
4. make edits
5. adb push build.prop /system/
idk if your edit will work but thats how to do it without root and for some of the other things said in this topic you can ota in twrp but it will fail if modify anything like you just did
Hi Everyone,
I have a phone, the Huawei Ascend P7 -L10.
Some weeks earlier I tried to install Spotify in my phone, but I didn't manage to install it. After several attempts I end up crocking my phone.
It happened when I found some app that had apparent solution to solve Spotify installation problem. I don't remember the name of the app. Anyway, I found it effective so I tried to follow the instructions given. I made it, then the changes were effective. What the app does is to change the phone model and respective carrier.
All the dilemmas started when I decided to restart the phone.
Here goes what I've done so far after the incident.
1. I tried by myself to restore/upgrade the system. I've experience doing this.
2. I took the phone to the 1st Repair Agency - they did not fix it
3. I took to the 2nd Repair Agency - the same thing, they fail to fix it
Note: When you try to restore the phone it gives the following information “update failed!"
and when you normally try to switch the phone on it stop on black screen and nothing else, I've also tried wipe cache, wipe data everything but nothing. Please help!!
Sounds like it might have modified your build.prop (general explanation of build.prop is here: http://forum.xda-developers.com/android/general/explanation-build-prop-values-t3069341). Basically this file found in /system dictates a lot of settings and modes for the phone to do and be in. If you are rooted, then you can view the build.prop with a build.prop editor, text editor, or root enabled file manager. If you aren't rooted, then you will have to see if there is a way to install TWRP recovery or you might be able to use adb if you can still get into your phone's settings. With adb, you should be able to pull the file to your PC then edit it back to the correct info. You might need to see if you can download a rom that will have this info or get someone in the forum for your phone to post it so you can verify that everything is the way it should be. Once that is done then updates should work again. Reason being is that most updates reference the build.prop to make sure it is installing to the correct device to avoid major issues.

Thanks for your replay. My device is rooted one, but the problem is, I can't login not even connect it via cable (using e.g. HiSuite). So, how can I pick up the file from phone?
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!

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://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/

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
Click to expand...
Click to collapse
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!

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.

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.

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?

Can’t get into settings. Tried the power button variations, with and without mini usb plugged in to the pc.
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,

All, I have found a solution to get this P-WAL-107-ELC-02 unlocked and usable!

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://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.
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!

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

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?
