[Q] AT commands with samung mobile C3222 and Linux - General Questions and Answers

I am using the UBUNTU 12.04 LINUX and I am tring to do some tinkering with USB devices and AT commands .
I have successfully accessed my Huewei E150 USB modem via terminal and also sent a message and called from it.
by using (as a root)
cat /dev/ttyUSB2 (in one terminal)
echo "<AT COMMAND>" > /dev/ttyUSB2 (in another terminal)
now I want to do the same with my samsung C3222 chat .
I have found the device file for it as /dev/ttyACM0
and I am getting the outputs that the system does with it by typing the command
cat /dev/ttyACM0
(which shows that all the drivers are OK and I am able to connect to it)
but the problem is I am not able to communicate with it as I was doing with Huewei modem .
Some of the commands I am trying to do are
"AT"
"ATI"
"ATD<mynumber>"
AT+CMGR"
but none of the above commands get response from the hardware.
I need some help as I don't know how the samsung phones works with USB ? Where am I going wrong?? are there are different AT commands for SAMUNG phones .

[Q] LG Thrill 4G new ROM Help

I have a LG Thrill 4G. I rooted the phone using superonelick, root checker says it is rooted. Downloaded ROM Manger and flashed clockworkmod. I cannot click boot into recovery, it just restarts the phone. I have tried to reboot into recovery by pressing 3d button, down volume, and power and it boots me into the android recovery but not clockworkmod, so I can not find anyway in to download the new rom from the zip file. Has had any other people had trouble with this? I have spent over 2 days searching the internet but I cannot find any similar problems, is there anyway to get into the recovery mode to install the new ROM without it just restarting the phone?
LG Thrill 4G ClockworkMod Installation (correct method)
1) You need to have ROOT access at the least (see link below)
It will also be good to have ADB (and hence LG Thrill drivers) installed properly
http://forum.pandaapp.com/thread/2/11/20110919/4e77f603d22632913-1.html
2) Get the recovery image from here and keep it on your PC in a folder accessible by ADB.
OR (if no ADB then) directly put it on your LG Thrill SDCard root
http://forum.xda-developers.com/showthread.php?t=1257588
4) If you have ADB then follow the instructions in the first link above to push the recovery image to your phone.
OR
if no ADB then open Terminal Emulator (install it from Market) and type su and click allow if the prompt comes up
5) Now you can follow instructions in the first link (far above) again, starting from the 'dd if=...' step. But instead of rebooting you could just power off
6) Clockwork recovery should now be flashed. To enter recovery, keep the 3D button, Vol-down and Power button pressed until you see the LG logo
Thank you for getting back with me. I tried to follow these steps and when I am in the Terminal Emulator and type adb push recovery.img /data it comes back with adb: not found. I have redownloaded the recovery file that you have attached to the SD card, same error, and then I tried to copy to the phone itself and same error. I can do any of the other prompts for the emulator but nothing that has to do with the recovery file it will not work. I am guessing maybe this is the problem because if it cannot find the recovery file, I cant do much of anything else. Do you have any suggestions of why the file still cannot be found on my phone?
connect adb through tcp
Try this:
1. If you are using terminal emulator to access adb then try downloading the app called remote adb. This tool will allow you to connect your device via tcp. Take note of the ip adress and port number. Usually the default port is fine.
2. Now open sshdroid, connectbot, terminal emulator and start an ssh session with the adb shell. You must have the correct public ip and port entered in to access the adb via tcp.
3. Once you have made the ssh connection between what ever emulator you are using and remote adb, start a shell as su.
4. Type the commands mentioned earlier.
This should let you run the whole thing from within your phone.
Alternatively...
1. start remote adb on your device.
2. start a terminal or cmd prompt on your cpu.
3. cd to androidSDK\platform-tools
4. type ---> adb start-server
The server then sets up connections to all running emulator/device instances. It locates emulator/device instances by scanning odd-numbered ports in the range 5555 to 5585, the range used by emulators/devices. Where the server finds an adb daemon, it sets up a connection to that port.
Note that each emulator/device instance acquires a pair of sequential ports — an even-numbered port for console connections and an odd-numbered port for adb connections. For example:
Emulator 1, console: 5554
Emulator 1, adb: 5555
Emulator 2, console: 5556
Emulator 2, adb: 5557 ...
As shown, the emulator instance connected to adb on port 5555 is the same as the instance whose console listens on port 5554.
Once the server has set up connections to all emulator instances, you can use adb commands to control and access those instances. Because the server manages connections to emulator/device instances and handles commands from multiple adb clients, you can control any emulator/device instance from any client (or from a script).
5. type --> adb forward tcp:5554 tcp:5555
5. type ---> adb devices. In response, adb prints this status information for your device. If there is no emulator/device running, adb returns no device, and you have not made a tcp connection.
6. Take note of the serial number listed. You will use it later to direct commands to device.
7. Type --> adb shell
8. Type --> su
9. Use commands from other post to achieve whatever you need.
10. once finished with shell, type --> exit twice to leave the shell
11. Finally, type --> adb server-kill
Hope that helps. Seems like you were having issues making the connection from device to adb, so that is what I focused on. If I can help anymore, just ask. We are all continually learning and the only stupid question is the one never asked.

How to Internet Pass Through from Linux to Sensation?

Hi everyone
I have a Sensation 4g and my system runs Ubuntu 12.04.
I was wondering if there is any way to make Internet Pass Through work with Linux?
In Windows, I install the HTC Sync and it works, but what about Linux?
Thanks

It works by default
In windows it asks for htc sync coz it need drivers to recognize the device
In Linux drivers are not necessarily required
You can just connect the device and use Internet pass through
(if you got adb working on that pc already then you are good to go)
Sent from my pyramid.. Through blazing fast sonic waves
I remember this as well on Ubuntu 11.04 - I only needed to modify some lines for ADB to get it work
well add the attached 51-android.rules file to /etc/udev/rules.d/ ( remove the .txt extension to the file ..i need to add it to attach in xda )
and chmod it to 755
(i.e chmod 755 /etc/udev/rules.d/51-android.rules )
then try the pass through it might work
For me it is not working
Let me explain what I did.
First of all I connected my phone with the laptop. In the beginning the
Code:
adb devices
was giving me ??????????? but I restarted the server as root and then adb was recognizing my device properly.
Then I chose Internet Pass Through in my phone but despite the fact that Ubuntu recognize my phone as a Wired Connection 2 (Wired Network - HTC Android Phone) I don't have internet on my phone. Also when I chose the Internet Pass Through in my phone, the
Code:
adb devices
list is empty (is this normal?).
So, ganeshp I pasted the rules that you gave me in the /etc/udev/rules.d/ and I changed the permisions but no luck. It doesn't work.
Also, after enabling the Internet Pass Through after some minuter I get a failure message on my phone that says
Unable to connect to PC
Either you don't have the latest version of HTC Sync installed on your PC, or another phone is already using Internet pass-through on your PC. Please ensure......etc

davebugyi what lines you needed to modify in the adb to get it work?
No one has an answer for this? If you are using Internet pass through without problems in your linux OS share what you did to make it work.

I've got my HIS working in Ubuntu 12.04 (DHD also). No root access or adb needed. Just simple script for Network Manager. I've posted a blog entry about this, it's in Russian, but you can use Google Translate to read it. http_://blog.loquens.org/?p=489

all you have to do is to use sudo
HTML:
sudo adb devices
Do the following:
Press CTRL + ALT + T to open the Terminal.
Inside the terminal type:
Code:
lsusb
Output should look something like this
Code:
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 009 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 008 Device 003: ID 0bb4:0c86 HTC (High Tech Computer Corp.) Sensation
Bus 008 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 007 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 006 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Take note of these two values 0bb4:0c86 next to the HTC (High Tech Computer Corp.) Sensation.
Then type:
Code:
sudo nano /etc/udev/rules.d/51-android.rules
That will open a file named 51-android.rules then type:
Code:
SUBSYSTEM="usb", ATTR{idVendor}=="0bb4", ATTR{idProduct}=="0c86", MODE="0666", OWNER="username"
In the text above change 0bb4 and 0c86 with the numbers you got from the lsusb, and instead of the username type youre user name.
Press CTRL + O and hit enter, then press CTRL + X .
if your adb-server was running up until now you need to kill it and restart it as root so type the following:
Code:
adb kill-server
sudo adb start-server
Then to check if everything worked out type
Code:
sudo adb devices
If all went well there should be an output similar this and you are good to go:
Code:
$ sudo adb devices
List of devices attached
BLABLABLA device
Edit: I assumed by the way that you have turned USB Debugging on :> that covers adb part, for the Internet pass trough you dont need drivers for linux just select the mode when you connect your device and you should be good to go.

adb from smartphone to android wear with just bluetooth (no cables needed)

Hey folks,
Just wanted to share something I found that might be useful from time to time: how to send adb commands to android wear directly from your phone without any cables nor an extra PC.
This is a combination from different tutorials, made for different goals, so almost all credit goes to them
This worked from my Nexus 5 (4.4.4 stock, rooted) to a LG G Watch R (5.0.1)... but it should work with any combination as long as, your smartphone is rooted (but this is XDA so it has to be rooted )
First thing first, start bluetooth debugging in your android wear device (from the developer menu)
Now from your smartphone, start USB debugging (developer menu too)
At the bottom of the settings in the android wear app you should see a new option "Debugging over bluetooth", turn it on. You should get a message just below:
Host: disconnected
Target: connected
You will also get a permanent notification to remind you that debugging over bluetooth is active.
Disclaimer: su commands are powerful and with great powers comes great responsibility... so pay attention to what you do. In any case, I'm not responsable for any damage incurred to your phone, your android wear device, your cat, your home, your neighborhood, etc...
Open a terminal emulator in the smartphone paired to your wear device, where you can do "su" stuff, and run the following commands:
> su
> export HOME=/sdcard
> setprop service.adb.tcp.port 5555
> stop adbd
> start adbd
> adb devices <--- this should show you your own smartphone (with a emulator-5554, in my case)... you can actually shell into it if you like recursions .
SECURITY NOTE: This will allow the adb daemon to listen for tcp/ip connections from other machines connected to your wifi hotspot... I guess it will also allow machines sharing the same 4G cellular network you are using to connect, but what are the odds... In any case, and if I'm not wrong, any android version since 4.3 should give you a message telling you to accept the connection or not.... maybe in airplane mode with just bluetooth activated it would work and it would also be safer.
Continuing in terminal (the typical stuff we know already):
> adb forward tcp:4444 localabstract:/adb-hub
> adb connect localhost:4444
At this point your smartphone should buzz and ask you to allow a connection from your own phone. This time is the real deal, but just in case read carefully the message. It should say "Allow Wear Debugging?", so accept the connection and optionally mark the always accept option.
You will now have two emulated devices:
> adb devices
emulator-5554 device <--- the smartphone
localhost:4444 device <--- the android wear device
you need to specify for now on the target of your adb commands. For instance if you want to have a shell in the android wear device:
> adb -s localhost:4444 shell
That's it. Hope it works for everyone.
Ah! just one thing the value service.adb.tcp.port we set before disappears with a reboot (you can replace the word service with persist if you prefer to have it surviving the reboot... but I do not recommend it).
If you do not want to reboot but you want to disable it, run, as root:
> setprop service.adb.tcp.port -1
> stop adbd
> start adbd
to clean-up, from the terminal and as root:
> adb kill-server
You can also disable the adb debugging from the developer menu.
N.B. 1 . I guess the easiest thing to do would be to put all those commands in a script file and then just run as root:
> sh script_to_adb_wear.sh
N.B.2. I have not tried with fastboot... but that would surprise me if it works.... In any case, and IMHO, fastboot should only be used with the device connected to a computer via usb.
This isnt working for me on my OPO running CM12 unofficial... Running the commands gives me a blank adb devices window, any advice?
Hi,
I guess you get the empty device list after the "start adbd" command, right?
Just to be sure, before running the adb devices commad do "adb kill-server"
If adb devices still gives you an empty list of devices try with:
> adb connect localhost:5555
And check again. Usually, what should happen, the adb server detects a adbd listening in the port 5555 and it considers it is an android emulator and it connects to it automatically. Maybe in your case it is not connecting, so the connect command might help. Once you hace at least your phone showing you can run the other commands to access the watch.
Let me know if this helps

No credit. Just copied and pasted from OP. Thank you so much for this gusano!! Always find myself needing this . Now if you could just figure out fastboot [emoji57]
Oh my, thank you very much, I've been trying to do this ever since I got my watch but just didn't have the skills (still managed to fins an other way to send files from the phone to the watch and even install apk's), you're great man!

I'm pretty sure that in fastboot mode (bootloader) the bluetooth driver is not loaded, so I guess having fastboot with bluetooth is not possible. Furthermore, I would not trust a bluetooth connection to do things that could brick your watch... of course, the pogo pins is not what I call a super trustable connection either
The sarcasm was lost apparently ?
Grr. Got a replacement phone from insurance and the binary isn't there. Can someone please pm me the adb from system/bin?

ADB tells me that my device has not authorized itself as an adb connection. The problem is since it's not actually a standard USB debugging connection I don't get a popup to mark my device as trusted. Is there anyway to work around this?

How to enable USB debuggin with broken touchscreen?

Hi
I have a old nexus with broken touchscreen . I want to use it via mirror on pc.
unfortunatly USB debuggin wasn't enable so i can't install any app.
any tips?
thanks
PS: i saw many use usb adapter to connect a mouse but i don't have it
EDIT: right now i just need a rom/kernel with USB debugging mode enabled by default
the screen still works , only the touch screen is broken
power , and volume bottons still work
the device is rooted
If it's only installing apps you could install them via recovery. (as zip)
Or you could check for a cheap replacement touchscreen.

thanks for the answer!
sorry i forgot to mention that i need USB debuggin for make the app works correctly.
I'm trying now to find out what rom i have installed and maybe then find a kernel with OTG support . (yes i found a otg cable )
i'm not a expert of rooting
I think google has an app called voice control. Not sure how operational it is though. Supposedly you can control the entire system via voice.

Boot into Recovery and mount*Data*partition.
Open a shell on PC and type:
adb pull /data/property/persist.sys.usb.config ~/
Repace*~/*with home directory of your OS.
Open that file in a text editor and you would possibly see*mtp*written there. Change it to*mtp,adb.
Note that sometimes Android doesn't understand the text file changes if the line terminator is "DOS Terminators" which Notepad would probably do on Windows (mine is Linux so no issue here).
In that case, I would suggest not using*adb pullbut doing:
adb shell echo 'mtp,adb' > /data/property/persist.sys.usb.config
You may verify that the*echo*command overwrote the file by using:
adb pull /data/property/persist.sys.usb.config ~/
and seeing the file's content in some text editor.
Unmount*Data*and reboot into Android OS. USB Debugging would probably be enabled.

adb shell echo 'mtp,adb' > /data/property/persist.sys.usb.config
You may verify that the*echo*command overwrote the file by using:
adb pull /data/property/persist.sys.usb.config ~/
and seeing the file's content in some text editor.
Unmount*Data*and reboot into Android OS. USB Debugging would probably be enabled.

Reboot your phone into recovery mode.
Connect it to your computer.
Open the terminal and type:
cd ~/.android
adb push adbkey.pub /data/misc/adb/adb_keys
adb shell reboot
but it still says error : device unauthorizated . please check the confirmation dialog on your device
i tryed also with a different version of adb and now gives me after "adb devices" an "offline" response
NB: if i connect the phone (not in recovery mode) via usb i can copy files in and out (i can explore onlyfew folders) , maybe this could help.

Sorry but this could not help... Now only thing you can do is connect any USB mouse to your phone via otg cable (as it is not costly also), and you can also try USB gamepad. I also have used USB gamepad before when my touchscreen was not working.
Second thing you can do is download any android device manager for your PC like mobogenie or mobilego they directly install any app from play store to you android device, through USB.And I don't think they need USB debugging option to be enabled.

my problem is not installing an app (i could do it in recovery mode with a .zip) but enabling the USB debuggin
I have a otg cable but not the "Y" type ( the one with power source ) , also i don't know if OTG is supported by my kernel . I would like to install maybe another kernel which has OTG support and usb debuggin mode enable by default but i don't know what kind of rom i have D:
right now i just need a rom/kernel with USB debugging mode enabled by default

ADB Emulator 5554 offline

When I connect my pixel to my pc and go to adb, i'm seeing 2 devices on "adb devices" prompt
xxxxxxxxxxxx (the model for my phone)
emulator 5554 offline
this is since i updated my pixel xl onto Oreo.
I can use -d for adb commands, but the presence of the offline emulator means i can't fastboot command as it wont accept the -d in the string to select the phone.
I've checked online (lots) to try to see how to remove it, but does anyone have any ideas how i can remove the offline emulator (i don't even use an emulator) from my adb devices?
same problem here, and I don't have bluestack!
