After unlock/recovery/root, cannot use adb commands in Terminal Emulator

Hi all,
After unlocking/recovery/rooting via Heisenberg's guide, I then tried to connect to my Amazon FireTV via Terminal Emulator, but when I try any adb command from it, it says:
/system/bin/sh: adb: not found
What am I missing or forgetting to do? Thanks.

adb is computer -> phone connection. Adb cannot be used in terminal emulator.

I've been using the same ADB commands in Terminal Emulator on my Android phones for years...
Anyone?

Anyone? Would really like to be able to connect to all my Android devices...

Can anyone help me with this? I can't find anything online and surprised no one else is asking about the issue...

Same issue was posted here on reddit FYI: https://www.reddit.com/r/AndroidQue.../adb_tool_no_longer_available_on_marshmallow/
How can we connect to other Android devices via Android 6.0 devices if this no longer works?

USB Debugging Xtrons 8.0 BMW E39

Hello guys,
I have a PX5 HeadUnit for my E39, and right now im developing an app for it.
The problem: i can't find a way to connect the HeadUnit with my Notebook to directly debug it.
I have already tried it with an USB to USB-c cable, as i don't have any USB male to male cables here, but it was with no success.

Why not using adb over WiFi?

Actually, I didn't know that was an option...
I'll test it and report later.

Apparently adb over WiFi doesn't work without an USB connection first, so that one was not helpfull at all.
Edit: OK! I found the solution, WiFi over ADB DOES work without an USB connection first.
Simply follow these steps:
install an terminal app on your unit and type in the following lines:
setprop persist.adb.tcp.port 5555
setprop sys.rkadb.root 1
reboot
(install adb drivers on your pc, kinda obvious)
type in "adb connect [your device ip]:5555
done.

How do you connect via adb if you are not rooted?

The same steps should also work without root.
I'm sure that my device wasn't even rooted back then.

Azottu Head Unit - ADB trouble

Hello,
I bought few month ago a Azottu (allwinner T8 core) head unit and I'm trying to link it with my laptop using ADB.
The problem is the HU is USB Host, as well as the Laptop. So using USB for ADB is not possible.
I tried to make the link using Wifi; the HU is connected to the wifi and via the laptop I try to connect (using the ip of HU)
But that's not working.
Does someone manage to connect to a HU using ADB and Wifi ?
Of course the HU is on development mode (7890) and the USB debug is activated ([email protected])
Hope to your light and help. Thank you

install a terminal app on your unit and type in the following line:
setprop persist.adb.tcp.port 5555
Then reboot the device and you should be able to connect via adb over WiFi

Thank you, works better.
Now with
adb devices -l
List of devices attached
192.168.1.118:5555 unauthorized transport_id:2
But the device is unauthorized
So I tried to remove all the keys generated by adb on my laptop, and revoke the authorization on the HU (with a reboot for both) to resynchronize the pairing without success...
I tried to generate a new key with the adb keygen command, and then copy the public key (.pub) on the HU (adb push or cp from sdcard to /data/misc/adb/adb_keys) without success as well
Do you have any other idea ?
Thank you

To see "unauthorized" when using adb over WiFi with a head unit never happened to me so far. So I have no advice, sorry

RK3128 based device - usb adb not working

I am currently trying to gain access to a device based on the rk3128 and android.
There was an UART that allows me to access the serial console including su.
I successfully connected the device to my wifi. Currently I am struggling to enable ADB. It doesn't work via usb, even after typing "adb -d start-server"
using "adb -a start-server" doesn't work for me, as the server is only started on 127.0.0.1 (netstat).
Any idea how to get adb access over network?

ADB commands from mobile phone to head unit

If you want to execute ADB commands you can use a USB male to USB male cable but you can also do it wireless:
1. Activate USB debugging on your head unit
2. Install Remote ADB Shell from Google Play Store on your mobile phone: https://play.google.com/store/apps/details?id=com.cgutman.androidremotedebugger
3. Connect your head unit to the wifi hotspot of your mobile phone.
4. Start Remote ADB Shell and connect to the IP of your head unit.
5. Execute ADB shell command.
Here are some samples for the Junsun V1 headunit:
Get su rights:
Code:
su @#zxcvbnmasdfghjklqwertyuiop1234567890,.
Disable duraspeed:
Code:
setprop persist.vendor.duraspeed.app.on 0
Give authorizations to an app:
Code:
pm grant com.llamalab.automate android.permission.WRITE_SECURE_SETTINGS

Would this work on Joying head unit?

Just give it a try. I expect the su command with the "password" will not work but remote adb may be possible.
