Using the 'Official TWRP App', I created a copy of both the boot and recovery image.

For the next step, if the device manufacturer will not supply an updated ROM, can you use the hardware profile help find a close custom rom that may work here? if so, do you have any suggestions on next steps? I installed the 'Droid Info' app to view hardware info, but it was not as detailed as I had hoped.

Rockchip RK3288 model number AIO MW22-A32

I sent an email to service@mediawavepc.com and will report back once I get a response:

I purchased one of these recently and the OS is Android 4.4.4

Do you know where I can download the ROM, Recovery image file?

I believe that I saw that your website stated the OS to be Android 7.1.

Is it supposedly capable of Android 8.1?

<and thank you very much>

The unit I purchased seems to have only 1GB DRAM?!?

Any way to increase this? Any advice is greatly appreciated!

[General Questions and Answers] donclark:
I did not attempt. TechlandPC did respond and said that this model maxed out at 4.4.4. I was not convinced that the updated firmware will work with this device and could not find anyone specifically doing it to this device - and did not want to brick it. I was able to delete some large system apps and free up some space with OAndBackupX (Andorid 4+)- https://f-droid.org/en/packages/dk.jens.backup/

I know the topic is a few months old but I’m currently looking at possibly purchasing the 22” or 15” in models and wanted to see if there were any further updates? What is everyone using them for? I hope to use them with home assistant and fully kiosk…anyone know if it’s possible? Seems like there is enough interest, maybe we can get this tablet upgraded?
[General Questions and Answers] donclark:
I purchased the 22" for my 83yr mother. I created a desktop stand for her to use it to view her gmail, facebook, etc. Its fairly limited because of the small space on the device, So I found a way to move many of the apps to an external usb. It also does not have a camera - which would have been nice for her to be able to use to make videochats, but I could not get an external usb camera to work (tried 4 different makes/models). I never did attempt to flash and upgrade it.
[General Questions and Answers] Crazyshakespeare15:
Oh wow Don…good on you for getting your grandmother up and going with it. I’m a little scared to take the plunge not knowing if it can run what I need…how good is the browser (is the system sluggish?) They two I’m looking at say they have built in cameras (I too was hoping to use it) but I bet it will be a no go :/
[General Questions and Answers] donclark:
If it says in the description that it comes with a camera - you may be ok. Mine clearly stated that it did not have a camera.

It is responsive and works well. I did do something to make it sluggish but I do not remember specifically... it may have been that I came very close to maxing out the storage which caused the issue.

The other thing that I was really disappointed in is that it does not have an HDMI in. So I could not push video to it. It does have an HDMI port, but I havent tested if it does push video to another device since I didnt have a need to do that.
[General Questions and Answers] Crazyshakespeare15:
It’s good to hear it’s responsive (or was lol) maybe I should just bite the bullet and get it…if I can just get it to run Home assistant it will be golden…if you think of anything else or figure anything out let me know!
[General Questions and Answers] donclark:
If the Home Assistant app will run on 4.4.4 then you should be fine. I had to search around and find some apks on other sites so that they would work on this. I would think that the app description should provide this info.

My question to you is - why would you want a specific device to run Home Assistant? Will it not run on your cellphone?

Please keep me posted on your adventure!

I should have been more detailed in my description....I am currently renovating a commercial building into a home and want to have large touch screens at the entrances.

[General Questions and Answers] chriswkbrd:
FWIW, I have a paper weight if I can't at least upgrade it to 5.1.1. so I've got nothing to lose.

With the links provided above (though half do not work) I downloaded the RockChip tools, RK3288 files, and RK388 Nougat.

I can only get my Windows 10 PC to recognize it when connecting using a USB-A to the Mini-B port on the screen. When it does connect, it uses a generic Microsoft driver 10.0.19041.746 (2006). I've installed the driver provided in the RockChip tools, but it doesn't seem to work. When I try to manually assign it to the tablet, I get an error, something about it not being compatible and making sure it's designed to work with 64-bit systems, which is the one I chose. Btw, I also tried the 32-bit, and got the same error.

Next, I tried the Andriod Tool, but it doesn't find the devcie, even though my PC does (with the generic driver). I'm sure this is due to not being able to install the correct driver.

I'm also unable to boot to recovery. When I try, I get "No Command". Anyone else able to get to recovery?

That's all I've got so I'd be interested to hear anyone else's experiences.

@donclark That's what I've tried in those first two videos but the firmware tool doesn't recognize the tablet. In the second video, I did email the poster and asked if he could help with suppling the firmware. I'll update if I hear from them.

One concern with the tv box firmware is, will it recognize the touch screen? I don't know enough about the android OS and how it will function on different devices.

Regardless, I can't really do anything until I can get the firmware tool to see the tablet. I'll continue to play around with it when I have time, and will update if I figure anything out. Thanks for the extra info.
[General Questions and Answers] kernel610:
I also reached out to the owner of the YouTube video. He said they don't own this model and couldn't provide help. Anyone else have luck here. I have a similar use case as others here, I want to use the tablet as a wall-mounted dashboard for Home Assistant. I'd like to use Fully Kiosk but would be ok with using the website if necessary. Fully Kiosk requires Android 5.0 as a minimum. Even when I load an old APK that supports 4.4, the web view doesn't load which I'm guessing is because Android 4.4.4 did not support the newer web technologies. Any idea whether we can add that capability without upgrading the whole firmware? That would probably solve my need enough for what I'm trying to do. It's a nice tablet device if we can get it to work for the use case.

A vendor image is required before you can flash a GSI, just grab the vendor image, flash it and flash a GSI on top of it. You maybe you required to flash a kernel too!

head over to bootloader unlock section for your device and see which vendor is available for your device that works best.

[General Questions and Answers] mcflurryXD:
I have a few MW22-A32s and MW15-A32s (I believe they are 15" variants of the same thing), and I'd like to do this as well. I'm using one of each right now to RDP to a terminal server. Most have root access from a factory reset of the image, and I have VNC servers running on each for remote management. I would like to upgrade them if at all possible, since kiosk mode was introduced in Lollipop I believe, as well as support for newer apps.

I've noticed some of them don't have the exact same stock images. Some have apps that others don't have, some don't have an entry in Settings -> Display for a sleep timeout (which I want to prevent screen burn-in using Daydream), and I even have one that apparently root access doesn't work after multiple resets. It's got SuperSu, but every time I open it, it wants to download something and fails, and root checkers always fail. I also don't know if I can find any factory images for these devices if we need them. Maybe some of the info I just gave is helpful? I'm not sure.

All that to say I'll look into these videos and maybe try to flash one of them if the steps look like something I can do. I've rooted older devices before, and I even used ADB yesterday to try to get into the recovery for one of them, although I never got past the "No Command" error.

Edit: I cannot find these devices anywhere in the Project Treble list.
[General Questions and Answers] cladkins:
A bit of an update as I also bought 2 of these to use as Home Assistant dashboards, and went down quite a few rabbit holes with no luck. I've decided to go a bit of a different route. I poped the back cover to get a look at the LCD panel, its model number HR215WU1-120. I was able to find controller boards for this panel on AlieExpress and eBay. Decided to go the eBay route hoping it will get here sooner. My plan is to grab a Raspberry Pi and use that to run the panel. Im going to order the controller boards this weekend with hope to have this up and running by the end of next week.

Controller Board

Getting the rear cover off was fairly self-explanatory, with 10 small Phillips head screws and a spudger(Old Credit card). Removed the screws and ran the spudger around the edges and it popped right off. Don't yank on the cover as there are 3 wires connected.

Ill post updates here as I make progress.

Edit: It appears that this controller board has the same barrel jack and power requirements as the current internals.
[General Questions and Answers] donclark:
Great progress and thank you for the update! I am very curious to know if the controller board works (and if there is anything else you needed to do to get it going the way you would like). I am excited to see your next update!
[General Questions and Answers] chriswkbrd:
As @donclark said, thanks for the update! I gave up and was going to throw it way next week. Looking forward to your date. I guess I'll just hang on to this thing for a few more weeks... lol
[General Questions and Answers] cladkins:
Also had another revelation this weekend. Instead of a raspberry pi, i might track down a android stick of some sort and see if that works as well.
[General Questions and Answers] POS-Consulting:
Well, you may or not find this helpful but...

I just spoke with a tech at Techland PC. They actually built the MW22-A32 as a special project for a line of clinics to use as registration kiosks. There is no upgrade path for this model, period. His only suggestion was to purchase a newer version (we all bought these because they were cheap on Ebay, so likely not going to happen) and currenty they only have the 32" version priced at $1400.00 USD. I (think) he said they are on Android 9.1, but definitely higher than the 7.1 advertised in the product brochure.

http://techlandpc.com/wp-content/uploads/2020/11/TL-MW22-A32.pdf

Finally got the controller boards, they work just fine. My struggle now is the capacitive touch controller. I'm trying to figure out how to adapt the Capcitiver touch controller to a raspberry pi.

I'm pretty impressed with everything you've done. I did try to see what I could find on the mb but I didn't find anything that hasn't already been posted here. Thanks for the update.
[General Questions and Answers] cladkins:
I was able to get ahold of SSA via WhatsApp and they unfortunately don’t sell just the newer motherboard. All is not lost though, I realized today that the capacitive touch controller can take a 4pin JST connector which will allow it to connect via usb to the raspberry PI. Most of the supplies I need will be here in a few days, I’ll keep updating as I go and if all is successful I’ll do some sort of write up with instructions and links.

For those looking to build a HAOS dashboard, I came across the ability to add a voice assistant to a Raspberry PI zero W. I grabbed a motion sensor, mic/speaker tophat and hopefully will be able to add some voice assistant capability as well.
[General Questions and Answers] cladkins:
Well, not great news. I was unable to solder to the built-in Touch Controller for the monitor. The pads are just way too small. At this point, I'm calling this a lost cause. I'll hold onto them for a bit in case anybody else has any ideas or leads on how to connect the touch controller to a Raspberry Pi.
[General Questions and Answers] adamkoehler1990:
can you post a picture of the size of the pads with a coin or something for reference? I might have an idea
[General Questions and Answers] Saboral:
So I successfully soldered to the connections for the touch controller. Is it possible to get links to the LCD driver and other components you used for the PI swap?
[General Questions and Answers] Saboral:
Also jumping down many many rabbit holes, I think the way to get this thing reflashed is going to revolve around shorting the CLK pin for the eMMC module to ground. I believe the manufacturer may have used secureboot which has disabled all the potential to use the AndroidTool and Loader mode. The eMMC will have to be bypassed to get to the flashing. I've examined but I need to get a scope out to look for the CLK pin as its not evident from visual examination.

If I conduct the Pi swap, I may do some more testing since the mainboard will be useless at that point except to figure out how to get around the manufacturer's obfuscation.
