CD-18781Y (Lenovo ThinkSmart View) Bootloader, Firmware, Zoom/Teams Conversion, Normal Android

[remrog]

After hours of trying and failing, I am really struggling with this

The flashing is no problem, I have tried all the versions above - but non of them gives me ADB access.
I got it once when installing the Zoom version, but after a reboot i was never able to access ADB again.

Im now on 200628.084. Developer Mode is activated but PC (several tried) will not connect via ADB.
I never get a question/pop-up to "Allow USB Debugging" either.. (Exept the one time on the Zoom image)

Anybody have any tips on how i can proceed?

EDIT: I got ADB to work, i changed the USB cable to another one and suddenly it worked

Hi,

a somewhat unrelated question:
I have a ThinkSmart View Teams.
However I can't use it because it fails the inTune compliance test. I just recreated the situation to check if I can find out what specific policy it wouldn't pass nbut I can't find it any more, however I believe I remember vaguely having seen once that it lacks (obviously):
- PIN (screen lock)
- encrypted file system
So as this is a corporate policy obviously I can't change it.
Is there a way to configure the device in a way so that it becomes compliant to the corporate policy?
Is there a way to get through to some android settings that enable PIN / FS encryption etc?

As I haven't used an Android device in literally 8 years or so, please excuse my dumbness

Well, so I decided to try to go the "flash & use for something else" - route.
But that's not overly successfull.

Mine is on firmware CD-18781Y.210507.111
So it propably has no ADB.

"press vol+ & vol- on powerup" is totally unsuccessful - i tried 10 times, it just boots up as regular.
"vol + & power up" brings the diagnostic menu but nothing to gain there.

factore restore -> configuration -> gear icon -> tapping on the firmware version doesn't do anyrthing, no matter how fast or often I tap.
So: I need to flash.

Installed the qualcom drivers (tried both options: WWAN & eth network).
the device is found in windows and I can open it up as USB storage, so the driver seems to work fine.
But it's nowhere to be found in device manager and QFIL shows me no port.

So what did I do wrong?
If the driver allows me to use it as a USB device, it's obviously working, right?
Any hints here?

Thanks!

Try to check the ADB connection.
Install ADB.
Connect the wire to the Usb 2.0 port (black, NOT BLUE) and to the tablet.
Launch "ADB"
Input the command "adb devices" and press enter
See if there is a name for your device?
If there is, copy "adb shell am start -a android.settings.SETTINGS" into the adb window and click enter.
A real system menu will open on the device.

Hi,

thanks so very much for helping.
But somewhere I must have taken a wrong turn:
I have ADB installed.
I don't think my laptop has a USB2-port so I went from USB 3 through a USB 2 hub to the device.
Device is showing as a USB storage device in Explorer, but stil ./adb devices will never show any device.

Is this because the USB 3 - port? Then I would set up an older laptop.

There may be problems with the usb 3.0 port. I couldn't flash through it, but it flashed through usb 2.0

Aaaand it worked...

I guess it wasn't USB 2/3, but the fact that I did need to use a specific version of the QFIL (the one included in the QPST package and not the one downloaded speerately).
Then I installed Nova launcher, switched to it, installed a button remapper, set my buttons, installed the Amazon App store (I suppose the google play store won't work, right?), installed myself the HomeAssistant App and...
...have myself a great new homeassistant status device.

Thanks!!

Hi,
I tried the QFIL included in the QPST package:
same result: no adb
I can have fastboot or COM driver
flashed with 200628.084 Teams & Others (ADB Turned on by default)
But unable to connect via adb (empty devices list )
some help

Connect the wire to USB 2.0. Install the program - ADB Installer v1.4.3 (including Google driver) from here https://forum .xda-developers.com/t/official-tool-windows-adb-fastboot-and-drivers-15-seconds-adb-installer-v1-4-3.2588979/

 

[badtown]

yeah !!
I pass through a hub: usb3 --> usb2
Boot normally (don't press any button)
In device manager:
Android Composite ADB Interface
USB\VID_18D1&PID_4EE7&REV_0318

And: All is fine, I can use adb
Now, I can install apk (nova launcher, button remapper, radio ..)
THANKS

Made TWRP. Works. The touchscreen starts only after the screen goes off with the + or - button.
- replace it in the folder with the firmware.
- install using qpst.

Well, what a ride:
I initially bought this device to use it for work. However after I switched work places after a few months it turned out not to be compliant with my new place's intune policies.
This is why I was trying to get a proper launcher onto it int the first place - to use it for something else.

Now with the new launcher, I tried to use it with the Homeassistant app. And failed.
It will connect to my HA server and show the URL and promt me to enter a user/pw, but then fail with "unable to connect". I removed the app, re-installed, deleted the cache... nothing. It just doesn't work.

BUT.... Since I now have access to the devices' settings I switched on "PIN"; encryption was already on and then thought... "hmmm... I wonder what other requirements intune might have"... so I tried authenticating in Teams once more and what do you know... It works.

Now the unit doesn't work for HomeAssistant but in exchange it does work for its initial purpose

I call that a win

Have fun you all with your smarties!


Oh, by the way... did anyone try to install the playstore or are there so many google services missing that it won't work?

I tried. It kept crashing. even tried several different guides on installing gapps, but none worked. I ended up installing the Aurora store.

The gapps will not be installed until the android build on the device is registered.
This device is not registered. and there are 2 possible solutions:
-need to change the build.prop and vendor.prop parameters to the registered ones
- replace the Google ID

Hi Guys. I'm trying to use Teams version for zoom, but I get "update" Error. "Zoom rooms must be upgraded to join this meeting. Please contact IT for assistance."

In ZDM I do not see ability to update firmware or software.
FW is CD-18781Y.210602.2103
App version is 5.6.3

Are there any users who use Teams panels converted to zoom normally?

One more thing: So as described I have my Thinksmart running teams again, but I'm wondering:
The device does not allow to apply background blur in teams. The option is simply not existing.
Which is obviously available in Teams for android IF the follwoing requirements are met:

Android requirements​

To change your background, your Android device must have the following:

• Teams mobile app for Android (version 1416/1.0.0.2021143402 or later)
• Android version 10 or later
• GPU
  • Qualcomm Adreno 610 or later
  • Arm Mali-G71 or later
  • Arm Mali-T720 or later

That would be a "check" for the App version (interestingly enough the app must have updated itself at some point)
But what sort of GPU is used in these devices? How would I find out?

I have Firmware 200628.084.
What Andorid version is that? Can Android be updated? independently of the firware?

Is there any chance I can get "background blur" or is the thing just not powerfull enough?

I checked for you and blur does work. When I first open teams it says "teams won't run without google play services", but I didn't encounter any issues with the things I did try.

To answer your other question it runs Android Things not stock Android. Android Things was discontinued in 2021 if I remember correctly. I do know the last version was 8.1. From what I can tell there isn't a lot of difference in stock android.

I hope someone writes custom firmware for this, but that is way beyond me.

 

[Xi07]

If there are problems with the navigation buttons. I'm putting it out the navigation button program.set as a regular apk. It is enabled in special features.

 

[Xi07]

For those who do not want to replace build.prop, I upload a Google id substitution program. set as a regular apk. After installing and running the id substitution, install Google play.

The description of the program specifies the requirement for teams android 8.0 and higher. Firmware 200628.084 has android 8.1
