Editing Lenovo ThinkSmart

=Installation=
;1. Go into your home directory:
 cd /~

<br>
;2. Install git and python if you don’t have them installed already:
 sudo install git
 sudo install python3

<br>
;3. Run the following commands to prepare the required binaries and the EDL tool
 sudo apt install adb fastboot python3-dev python3-pip liblzma-dev git
 sudo apt purge modemmanager
 git clone https://github.com/bkerler/edl
 cd edl
 git submodule update --init --recursive
 pip3 install -r requirements.txt
 sudo cp Drivers/51-edl.rules /etc/udev/rules.d
 sudo cp Drivers/50-android.rules /etc/udev/rules.d
 python3 setup.py build
 sudo python3 setup.py install

:<b>Note: What is the EDL tool?</b>
::The EDL (Emergency Download) tool is a special mode of operation for Qualcomm MSM based devices The EDL mode itself implements the Qualcomm Sahara protocol, which accepts an OEM-digitally-signed programmer over USB. The programmer implements the Firehose protocol which allows the host PC to send commands to write into the onboard storage (eMMC, UFS).

<br>
;4. Download the file: [https://drive.google.com/file/d/1vnRMgf0pac1uKbdNDqJTANmH1t6IgflV/view?usp=sharing. kingston-ha-rom.7z]

<br>
;5. Move the kingston-ha-rom.7z zip file to a temporary folder, extract all of the archived files. Next, delete the 7z file then move the contents of the temp folder to the edl directory that was created by cloning the git repository.

 mkdir temp
 cd temp
 mv ~/Downlads/kingston-ha-rom.7z . 
 7z x -o./ kingston-ha-rom.7z
 rm *.7z
 cd ~/edl
 mv ~/temp/* .

You should see three new folders in the ~/edl folder:
 bin
 extras
 flash

<br>
;6. Before you flash the ThinkSmart device
The default boot screen is vertical, if you want to change that, you need to do it before flashing the device, by renaming splash.bin to splash.bin.vert and splash.bin.horiz to splash.bin (see Extras & Notes in OP).<br>
(I don’t know which splash.bin needed changing, so I did both.)

 cd ~/edl/flash
 mv splash.bin splash.bin.vert && mv splash.bin.horiz splash.bin
 cd ~/edl/Drivers/flash
 mv splash.bin splash.bin.vert && mv splash.bin.horiz splash.bin

<br>
;7. Flash the ThinkSmart device:
cd into the edl/ directory and run the EDL command:
 cd ~/edl
 ./edl qfil ~/edl/bin/rawprogram.xml ~/edl/bin/patch0.xml ~/edl/flash --loader=~/edl/bin/prog_emmc_firehose_8953_ddr.mbn
The terminal will show marching dots (…) as it is looking for a connection to an Android device.

<br>
;8. Connect the Lenovo device via USB C
The USB-C connector is behind a rubber plug on the bottom.

;9. Press both volume buttons and connect the power to the device.
I recommend using a switched outlet strip because you will be powering the device off and on a few more times.
After a few seconds the terminal will show the device is connected and the flashing is proceeding. (You can release the volume buttons now).

<br>
;10. When the flash finishes, remove power cable or switch the power strip off.

<br>
;11. Put the device into the recovery mode.
Power the device with the volume-up button pressed. The buttons aren’t labeled, but volume-up is the center button.

<br>
;12. Select “Wipe data/factory reset”, then Select “Reboot Now”

<br>
;13. Finish up user provisioning:
Once you see the Lock Screen, run these ADB commands to finish up user provisioning:

 adb shell settings put secure user_setup_complete 1
 adb shell settings put global device_provisioned 1

<br>
;14. (Optional but recommended)
Install and start the virtualsoftkey app
 ~/edl$ adb install extras/virtualsoftkeys.apk
This gives you three navigation buttons at the bottom of the screen: Back, Home and History.
.###(I think you have to reboot to make the navbar active)
:VirtualSoftkey settings:
:From the home page, tap the VirtualSoftkey app icon.

I set the navbar to hide after 5 seconds. To get it back, swipe up from the bottom of the screen. To hide it before the timeout, swipe down on the navbar itself.

<br>
;15. Configure your wifi
Settings > Network & Internet

<br>
;16. Install the HA app from the Aurora Store
.### I got a page full of errors when I installed the HA app. but upon reboot, the Home Assistant app was on the home page and it does work.

=Problems I encountered:=
I never saw this:

In Aurora setup, choose ‘Aurora Services’ when asked for an installer.
The first time I ran Aurora Store, I signed on with my Google account and was presented with the Aurora Store. There was no “Aurora Services”.

Transfer over the included wallpaper and install a gallery app, so you can set it:
   adb push extras/wallpaper.png /sdcard/Downloads/
   adb: error: failed to get feature set: no devices/emulators found

   adb install extras/gallery.apk
   error: no devices/emulators found
   error: no devices/emulators found
   Performing Streamed Install
   adb: connect error for write: no devices/emulators found
Then after the first boot (and provisioning)
adb root && adb remount
This did not work for me, the terminal just hangs. This worked:

 ~/edl$ adb shell
 CD-18781Y:/ $ su
 CD-18781Y:/ # mount -o rw,remount /system
 CD-18781Y:/ # exit
 CD-18781Y:/ $ exit
.### Other issues:

 ~/edl$ adb shell mv /system/media/bootanimation.zip /system/media/bootanimation.zip.vert
   mv: bad '/system/media/bootanimation.zip': Permission denied

 ~/edl$ adb shell mv /system/media/bootanimation.zip.horiz /system/media/bootanimation.zip
   mv: bad '/system/media/bootanimation.zip.horiz': No such file or directory
'adb remount’ for some reason is hanging

 Try turning on developer mode in settings.
 Tap build number 7 times in settings → about.

;auto load the HA client app on boot<br>
Wallpanel (GitHub - TheTimeWalker/wallpanel-android: WallPanel is an Android application for Web Based Dashboards and Home Automation Platforms) has an option for start on boot<br>
<i>WallPanel wouldn’t install. No error messages, it just hangs.</i>
