Hi,
Finally I can enter recovery mode after messing up with build.prop on Xperia Tablet S
tablet is visible in ADB as
C:\Users\Amiga\Desktop\adb>adb devices
List of devices attached
0123456789ABCDEF recovery
but rest of the commands doesn't work
C:\Users\Amiga\Desktop\adb>adb shell
* daemon not running. starting it now on port 5037 *

The reason you are getting the "error: closed" message is because the version of System Recovery installed on your tablet inhibits ADB from accessing the tablet's file system. You are not going to be able to pull or push the build.prop file.
Ok I can't use ADb so how can I replace faulty build.prop file or make recovery? Any ZIP file that I can put on SD card?

You can try copying an OTA update file to an SD card and using System Recovery to install it, but I do not believe doing that will work. I believe you have bricked your tablet to the point where you have to send your tablet to Sony for repair.

Hi cat tried to PM you but can?t do it...
Can you teach me how to copy/restore (pull and or push) the original build.prop in my cell (now bricked) i had the original file (buil.prop) inside it... i am learning about adb commands. thanksss. The main problem I have: An issue with ADB VCOM drivers (in windows) (tried in a couple of PCS, the device manager "see" the vcom preloader only a little moment (when connect the cell with usb cable) and then dissapear... then with command adb devices: no devices found... can you help me?

The reason ADB is reporting no devices are found may be because (1) your device is bricked, which probably means you are not going to be able to pull/push files from/to your device, (2) you do not have ADB drivers for your device properly installed on your PC, and/or (3) you do not have USB debugging enabled in your tablet's Developer options settings.
It's good you are learning how to use ADB and there are plenty of ADB tutorials to be found via Google, etc.; e.g., HERE.
Here is what you specifically ask for.
Pulling the build.prop file from your tablet to your PC is easy, just use these commands.
Code:
adb wait-for-device
adb pull /system/build.prop
adb kill-server
Pushing the build.prop file from your PC to your tablet is more complicated.
(1) Your tablet must have root access. If it doesn't, attempts at pushing the file to your tablet's /system directory will fail.
(2) Along with having root access, you must have SuperSU or Superuser, and Busybox installed on the tablet.
(3) You have to temporarily set your tablet's /system directory's properties from RO to RW, which must be done quickly because your tablet's OS monitors the /system directory's properties and will reboot the tablet if it detects the directory's properties have been changed from RO.
(4) To issue the ADB commands as quickly as possible, the commands must be put into a DOS batch command script file. For example, create and run a batch file named doit.bat containing the following commands.
Code:
adb wait-for-device
adb push build.prop /build.prop
adb shell "su -c 'stop ric'"
adb shell "su -c 'busybox pkill -f /sbin/ric'"
adb shell "su -c 'mount -ro remount,rw /'"
adb shell "su -c 'chmod 0440 /sbin/ric'"
adb shell "su -c 'stop ric'"
adb shell "su -c 'busybox pkill -f /sbin/ric'"
adb shell "su -c 'mount -ro remount,rw /system'"
adb shell "su -c 'busybox cp -af /build.prop /system/build.prop'"
adb shell "su -c 'chmod 0744 /system/build.prop'"
adb shell "su -c 'rm /build.prop'"
adb shell "exit"
adb kill-server
Good luck.

Wowww Cat, you are the one!! Thanks in Advance
The main problem I have: An issue with device recognition in windows PC... driver ADB VCOM MTK 6592 (tried in different PCS windows Xp and 8) (the device manager "see" the vcom preloader but only a little moment (in the first instant when connect the cell (cell off) with usb cable) and then dissapear (disconnect) the vcom preloader... I think If I can reach the way to get this connection running ok I can progress with this... will fight hard...
When I type the command adb devices, result: no devices found...
Tried to upgrade the vcom drivers (when i can catch it in the active state in device manager)... nothing
Tried to "on" the phone... nothing
Tried to flash a new ROM from Recovery (MIUI or Feelingme 078)... ERROR installation aborted
I can see this effect (with usbview): the usb is recognized in the PC (but just for a little moment at the instant when plug it), then disconnect...
I need to recover the original build.prop.bak from coolpad memory, rename it to build.prop and send it to coolpad again...
I think i can flash (from recovery) an original build. prop (packed as update.zip) doing the wipes and apply update from sdcard)... anyone can assist me on this?
This new 9976A item comes to me with 048 version, custom buid version 265 and rooted from factory...
Anyone can please help me?

adb push build.prop /build.prop
is it ok? or the path is this?

You need to solve that problem before you can do anything else. Find an xda-developers forum that deals with your device and look there for fixes for your device's drivers. I am confident I can help you with Sony tablet drivers, but not your device's drivers. I don't even know the model of your device.
Create and use the following CheckDriver.bat file to help you troubleshoot the drivers. The script simply opens a DOS command window, starts the adb server, then lists the devices the adb server finds. The DOS command window will stay open until you press any key. If the script hangs, press ctrl+c to abort the script and close the DOS command window, then open another DOS command window and issue the "adb kill-server" command to stop the adb server.
Code:
@echo off
echo Starting ADB server and waiting for device.
echo.
adb wait-for-device
adb devices
pause

Looks okay. Just keep in mind that the scripts are based on what is required for Sony tablets. Your device may require something a little different.

No. The "adb wait-for-device" command is what starts the adb server and causes the script to wait until the adb server detects a device before the next command in the script is issued.
Similar to the CheckDevice.bat file, you can insert the "@echo off" command at the beginning of your .bat files and the "pause" command just before the "adb kill-server" to cause the DOS command window stay open so you can see what is going on and the DOS command window will stay open until you press any key. Again, if the script hangs, press ctrl+c to abort the script and close the DOS command window, then open another DOS command window and issue the "adb kill-server" command to stop the adb server.

Sounds to me your device simply is not responding to the adb server's attempt to connect. Again, my advice is for you to find an xda-developers forum that deals specifically with your device and look there for fixes for your device.

Thank you for the info,
but it's not working on Recovery mode!
I try to backup and restore the build.prop file on cmd in recovery & in bootloop case.
working:
adb wait-for-device
adb pull /system/build.prop.bak or adb pull /system/build.prop
adb kill-server
not working push to the system: (even the cmd showing the opposite)
adb wait-for-device
adb push build.prop /system/build.prop
adb kill-server
I'm tring to resotre from PC or SD card...
(after changing the permission to system folder (instead only build.prop file) to 00644 the device keep get to Recovery mode! (with root browser app)
only flashing again the rom fix it.)
I got an error too:
- exec '/system/bin/sh' failed: Permission denied (13) -
by the way what Should to be on?
SuperSU or Superuser (ADB shell allow ?)
Developer Mode (Enable ADB ) +USB Debugging on
i'm worng what else?
I want to add some info:
I know the best way to edit this file only by : Notepad++ or EditPlus editor to preserve UNIX encoding
or Turbo Editor ( File Editor ) app.

will this work too on recovery or bootloops mode?
backup:

Hacking android, got "system" user, but not root, how to escalate privilege?
Hello, i am new to XDA. I am trying to jail-break my android device:
Android 5.1.1, Linux 3.10.49
This device is a rare brand and have no any unlock & flash mechanism.
Currently i have successfully got "system" user (UID 1000) by using a preinstalled DEBUGGABLE system app.
This user can only change /data directory etc, it can not change any file owned by root.
So any help to escalate "system" user to root user will be very appreciate.
the result of command "id":
Code:
uid=1000(system)
gid=1000(system)
groups=1000(system)
1007(log)
1010(wifi)
1015(sdcard_rw)
1021(gps)
1023(media_rw)
1028(sdcard_r)
3001(net_bt_admin)
3002(net_bt)
3003(inet)
3004(net_raw)
3005(net_admin)

3009(qcom_diag)
9997(everybody)
41000(u0_a31000)
context=u:r:system_app:s0
This account can change /data/system/packages.xml etc, but can not change /system/*, nor chown/mount.....
It's CapBound is 0, too strict. And also can not disable SELinux.
Can anyone help me?
----------------------- PS: share how i get system user privilege, maybe helpful to others -----------------------
In a word, just use jdb to attache to the app then print new java.lang.Runtime().exec("sh /sdcard/my.sh").
First, i found a package appeared in Android Device Monitor's debuggable app list, e.x. com.example.app.
Then i use
Code:
pm dump com.example.app
got confirmed it use system UID, then
Code:
run-as com.example.app
but failed due to "Package not found", i don't know why.
Then i try to use JDWP way.
Get the debuggable process ID:
Code:
$ adb jdwp
9424
$ adb forward tcp:8600 jdwp:9424
$ jdb -attach localhost:8600
> threads
group system:
(java.lang.Thread)0x2a86 Signal Catcher ...
(java.lang.Thread)0x2a87 FinalizerWatchdogDaemon ...
...
group main:

(java.lang.Thread)0x2a8e Binder_1 ...
...

main[1] > print new java.lang.Runtime().exec("sh /sdcard/qj.sh")
There are some files need be upload(adb push .... ) before run the last command.
/sdcard/qj.sh:
Code:
date > /sdcard/log
cp -f /sdcard/busybox /data/ 2>> /sdcard/log || exit 1
chmod 4777 /data/busybox 2>> /sdcard/log || exit 1
(while true; do /data/busybox nc -l -p 7777 -e sh; done) >> /sdcard/log 2>&1 &
echo server OK >> /sdcard/log
/sdcard/busybox:
this file can be found at busybox.net/downloads/binaries/latest, choose ARM7v.
The above jdb command "print new java.lang.Runtime().exec("sh /sdcard/qj.sh")" will create a shell server listening at 7777 port, bridge input/output to sh.
So, to connect to the shell server,
Code:
adb forward tcp:7777 tcp:7777
nc localhost 7777
then in this connection, input shell command.
Sorry: i forgot a very important step: to run the "print new ...." statement, i have to turn on screen, even touch the app so can be trapped into jdb.
---------That's all------------
I found I can use these ADB commands to turn on and of the WiFi of a rooted phone:
Code:
adb shell su -c 'svc wifi enable'
adb shell su -c 'svc wifi disable'
However, I'm interested in doing it without having to root the phone for an automatic testing I'm doing. Do you guys know if this is possible?
I found this project which allows me to connect to a WiFi through ADB commands not being a root user. I was wondering if anyone knows how to disconnect also from ADB and not being a root user.
UPDATE:
I've been recently trying:
Code:

I also found doing this type of command:

adb shell input keyevent 20 & adb shell input keyevent 23
I can navigate and click. The problem seems to be that I always finish in a different state so the next time I input the command
Code:
adb -s serial_number shell am start -a android.intent.action.MAIN -n com.android.settings/.wifi.WifiSettings
I start in a different place and start clicking elsewhere. I've tried returning home, but that doesn't fix the issue. Is there any way to start always from the same point inside the WiFi settings?
Thanks!

I found I can use these ADB commands to turn on and of the WiFi of a rooted phone:
Code:
adb shell su -c 'svc wifi enable'
adb shell su -c 'svc wifi disable'
However, I'm interested in doing it without having to root the phone for an automatic testing I'm doing. Do you guys know if this is possible?

Turn WiFi off
Code:
adb shell settings put global airplane_mode_on 1
adb shell settings put global wifi_on 0
adb shell settings put global wifi_scan_always_enabled 0
Afterwards you've to re-boot the device.

Thank you, but those don't produce any change on my device. Actually, if I put the first two commands without doing "adb kill-server" in between, I get this message:

But the output when they work is:

I've been recently trying:

This opens the screen where you can turn on and off the WiFi but it doesn't do it...not sure if I'm missing something!
Just to be shure, make shure your using the latest version of ADB offered by google here:
https://developer.android.com/studio/releases/platform-tools
You could use adb wifi
After activating when using usb it and connecting through the same wifi:
svc wifi enable
works without root
I'm a little late to this thread, but if it still helps the OP, non-rooted Android 10 and below allowed wireless adb connections AFTER a USB connection was first established (adb start-server && adb tcpip 5555 && adb connect [IP]:5555), but that changed (for the better) in Android 11 and above with the new new Developer options Wireless debugging random port assignments (adb connect [IP]:[PORT] or adb pair [IP]:[PORT] [PIN]) such that the adb wireless connection never needs USB cable ever again.
Given Android 11 allows Developer options Wireless debugging via a random port, and Android 12 new Developer options Wireless debugging allows that to be accessed even easier with a new Developer options Wireless debugging tile, the only thing missing is a way to turn the non-rooted Android Wi-Fi on or off via adb (which was the OP's original question after all).
Maybe this will work if we can figure out how to tap the buttons?
adb shell "am start -a android.settings.WIFI_SETTINGS"

For swiping on the phone from adb this works...
C:\> adb shell input swipe 500 1000 500 100
This will instantly swipe from center to the top of the screen.
You can add a time period, e.g., take 3 seconds to swipe that.
C:\> adb shell input swipe 500 1000 500 100 3000
Click to expand...
Click to collapse
But you want to tap the buttons, right?
If we can figure out the positions, maybe this would work?
C:\> adb shell am start -n com.google.android.gms/.ads.settings.AdsSettingsActivity
That should pop up an Android "Reset Advertising ID" settings page.
C:\> adb shell input tap 500 400
If run after the command above, that will tap the button to
asking to "Opt out of Ads Personalization" in that Activity
if that button is like mine, at the X=500 & Y=400 location.
On my phone, this is the "Reset advertising ID" button location:
adb shell input tap 500 200
On my phone, this is the "OK" button on that GUI above.
adb shell input tap 700 1000
C:\> adb shell am force-stop com.google.android.gms
If run after bringing up the advertising-id reset Activity,
it will close the activity without doing anything else.

Here is a somewhat related post...
[adb,scrcpy,vysor] What ports does Android 12 randomly set when Wi-Fi connecting via Wireless debugging adb "pair" or "connect" commands?
Type adb tcpip 5555 in the command line or Terminal and press Enter.
Find your phone's IP address in Settings > About Phone > Status > IP Address.
Back in the command line or Terminal, type adb connect [your Android's IP address].
Finally, press Enter again.

Hi, I'm just a newbie my phone reboots randomly and I'm trying to find the problem through Logcat so that I could send it though the Devs if its an software bug. I tried adb bugreport but I'm not sure what to look for then it seems that the timestamp starts after the phone reboots. but I couldn't replicate the reboot issue when Logcat is running trough ADB terminal. I've read somewhere its possible to see the "Last_kmsg" but it seems the terminal cannot find it. Any ideas how to narrow the bug report or other ways to get a log? Thank you
*phone is not rooted
*tried factory reset
*tried reinstalling latest software update
EDIT*
I managed to use "Logcat Reader" on android but since that the reboot is unpredictable. I can't save the logs before the reboot. I'm currently looking into other apps maybe theres an autosave incase the phone reboots.
EDIT2*
I was hoping I could get 'dmesg' log but ADB terminal says access denied maybe coz I don't have root access.
@JKD23
To get the booting process events from the logcat
Code:
adb devices
adb shell "logcat –d –b events ^| grep 'boot'" > C:\Android_Logcat_%DATE%_boot.txt
adb shell "logcat -d ^| grep 'preload'" > C:\Android_Logcat_%DATE%_preload.txt

Hi, thanks for replying. I entered those commands in the terminal but all I got was
"grep: 09/13/2020_preload.txt: No such file or directory" for both commands.
I can ad hoc open any given Activity on the Android phone while connected over USB to adb on the Windows PC, but how do I DUPLICATE the SAME THING, but from the phone itself?
For example, how can I run this Activity, ad hoc, on the Android phone?
ACTION: "android.intent.action.MAIN"
PACKAGE: "com.google.android.gms"
CLASS: "com.google.android.gms.ads.settings.AdsSettingsActivity"
Click to expand...
Click to collapse
For illustrative purposes, below is a trivial example of ad hoc opening the "Reset Advertiser ID" Activity on the Android phone.
1. Install & test adb on your PC (I tested this only on Windows 10)
2. Connect your Android device over USB (mine is Samsung, Android 11)
3. Paste this command into a Windows command window:
C:\> adb shell am start -n com.google.android.gms/.ads.settings.AdsSettingsActivity
That's just a trivial example where I can't yet figure out yet how to duplicate that popping up of a given Activity on the android phone for any given Activity, if all I know is the name of that given Activity (and which isn't already found in a static list inside of the shortcut creator apps).
Here are more examples I've tested for other Activities.
Code:
C:\> adb shell am start -n com.android.settings/.Settings
C:\> adb shell am start -n com.google.android.gms/.ads.settings.AdsSettingsActivity
C:\> adb shell am start -n com.google.android.gms/.location.settings.LocationAccuracyActivity
C:\> adb shell am start -n com.android.settings/.applications.ManageApplications
C:\> adb shell am start -n com.google.android.gms/.update.SystemUpdateActivity
C:\> adb shell am start -n com.samsung.android.secsoundpicker/.SecSoundPickerActivity
C:\> adb shell am start -n com.android.settings/.Settings\$NotificationAppListActivity
C:\> adb shell am start -n com.android.settings/.Settings\$AppMemoryUsageActivity
C:\> adb shell am start -n com.android.settings/.Settings\$NotificationAppListActivity
C:\> adb shell am start -n com.android.settings/.Settings\$SecDisabledAppsActivity
C:\> adb shell am start -n com.android.settings/.Settings\$PowerUsageSummaryActivity
C:\> adb shell am start -n com.android.settings/.Settings\$AppAndNotificationDashboardActivity
C:\> adb shell am start -n com.google.android.gms/.app.settings.GoogleSettingsLink
C:\> adb shell am start -n com.google.android.gms/.app.settings.GoogleSettingsIALink
C:\> adb shell am start -n com.google.android.gms/co.g.Space
C:\> adb shell am start -n com.google.android.gms/.gcm.GcmDiagnostics
C:\> adb shell am start -n com.google.android.gms/.nearby.exposurenotification.settings.SettingsActivity
C:\> adb shell am start -n com.google.android.gms/.nearby.sharing.ContactSelectActivity
C:\> adb shell am start -n com.google.android.gms/.mdm.settings.AdmSettingsActivity
C:\> adb shell am start -n com.android.settings/.network.telephony.MobileNetworkActivity
After each command line above you can close the previous results using the adb command shown below (because you can't open an Android Settings Activity on top of an existing Android Settings Activity):
Code:
C:\> adb shell am force-stop com.android.settings
I'm well aware that we can create permanent homescreen shortcuts using shortcut creator applications; but this question is not about creating a homescreen shortcut for permanent access to Android Activities.
This question is how to instantly open ANY given Activity ad hoc (i.e., on a case-by-case basis) on Android whenever you want to - just from the name like we did above using adb (but without needing adb to do it).
Pack all the ADB commands listed in a Linux shell script ( means omitting "adb shell" part ), put this script into /data/local/tmp, make script executable and finally run this script in Terminal Emulator on phone.

That worked! Thank you!
Below is my first testcase, which was the simple example of popping up the "Reset Advertising ID" Activity on Android when all you know is the unique name of the Activity.
This alias (which I named "resetadid") that worked first was:
$ alias resetadid='am start -n com.google.android.gms/.ads.settings.AdsSettingsActivity'
This saves that alias into your bashrc file for safekeeping.
$ alias >> ~/.bashrc
To run that alias at the Android Termux command line, I just type:
$ resetadid
(which will pop up the named Activity on your phone)
Then I put that line into a shell script that I named "resetadid.sh"
$ am start -n com.google.android.gms/.ads.settings.AdsSettingsActivity
And I put the following line into another shell script (named "closegms.sh") to close that gms (google mobile services) Activity.
$ adb shell am force-stop com.google.android.gms
Note for the shell scripts to work, I had to run these commands.
$ pkg install termux-exec
$ termux-fix-shebang ./resetadid.sh
Click to expand...
Click to collapse
This is the "./resetadid.sh" shell script that survives rebooting:
#!/data/data/com.termux/files/usr/bin/bash
am start -n com.google.android.gms/.ads.settings.AdsSettingsActivity
To run that script at the Android Termux command line, I just type:
$ ./resetadid.sh
(that will pop up the named Activity on your phone)
Normally we won't need to close that Activity because resetting the advertising ID will close it when we hit the "reset" and "ok" buttons, but for now we need to close the Activity after we pop it up.
To that end is this temporary "closegms.sh" shell script.
#!/data/data/com.termux/files/usr/bin/bash
adb shell am force-stop com.google.android.gms
There are only two things left.
1. How to put that Termux command in a homescreen icon for free?
2. What to add to that shell script to actually press the "Reset" button?
Anyone know how to add a shell script to the Android homescreen?
Anyone know how to add a command to press the "reset" button?
Typically by long tapping on the home screen, you can create a shortcut to an existing script or add a live folder that contains all of your scripts.
BTW:
Termux is a Terminal Emulator what allows you to run ( Linux conformant ) Android Shell commands / scripts.

Thanks for that advice which works to create, not a shortcut to a script, but a widget to a script (a shortcut would be nicer as it fits in homescreen folders).
It's not as simple as just long tapping because there is a ton of syntax involved, and the files have to be in critical directories, and even the version of Termux matters extremely greatly.
But it does work. Thanks.
So we can now create a homescreen widget that will bring up any given Activity if all we know is the Activity name!
I'll write it up in the next post.

The "right" Termux appears to be that on F-Droid and NOT the one on Google Play as documented elsewhere on the net, this being one link.
For this kind of shell scripts (to run Activities) do you think Andronix will help (Andronis is apparently Linux on top of Android along with Android without the need for rooting).
So we can now create a homescreen widget that will bring up any given Activity if all we know is the Activity name!
For anyone who reads this, may I ask that you please invest five minutes in testing this out and letting everyone here know how it works for you?
What I wrote below is designed so you can just follow the cookbook and you should end up with a widget on your homescreen which will open up to ANY named Activity (but I only give one example below) if all you know is the unique name of that Activity.
Install the F-Droid Termux
(Do not use the Google Play Termux!)
Install the F-Droid Termux:Widget
Start Termux on your Android device
All commands below are run on the Termux command line.
If you had to back out the Google Play Termux in favor of the F-Droid Termux, you'll want to re-create & re-test the alias to a simple Activity such as "Reset Ad ID" as explained earlier in this thread, just to test your syntax.
Re-create:
Code:
alias resetadid='am start -n com.google.android.gms/.ads.settings.AdsSettingsActivity'
Re-test:
Code:
$ resetadid
Then re-create & re-test the shell script we previously described earlier in this thread.
Re-create:
Code:
#!/data/data/com.termux/files/usr/bin/bash
am start -n com.google.android.gms/.ads.settings.AdsSettingsActivity
Re-test:
Code:
$ ./resetadid.sh
Now we're ready to put that command on your homescreen!
Create two directories which are defined in the Termux-Widget help.
Code:
$ mkdir -p $HOME/.shortcuts
$ mkdir -p $HOME/.shortcuts/tasks
Note I'm not sure what the "tasks" directory is for but Termux:Widget docs say to create it.
Move the shell script you created earlier into the $HOME/.shortcuts directory.
Code:
$mv ~/resetadid.sh $HOME/.shortcuts/.
Add the Termux Widget to your homescreen.
Long press your Android homescreen.
Select "Widgets"
Select "Termux:Widget"
Place that "Termux:Widget" on your Android homescreen
Click to expand...
Click to collapse
Depending on your Android version...
It will ask:
"Create widget and allow access?"
To which you press "Yes" to put your widget on the homescreen.
Click to expand...
Click to collapse
To interact with the now-running widget, just press the named entry showing up in that Termux Widget.
Code:
resetadid.sh
Depending on your Android version...
It may ask: "Termux requires "Display over other apps" permission
to start terminal sessions from background on Android >=10."
"Grants it from Settings -> Apps -> Termux -> Advanced" [sic]
Click to expand...
Click to collapse
If needed, grant Termux permission to display over other apps:
Code:
Android11:Settings > Apps > Your apps > Termux > Appear on top = (change off to on)
Now you can press the always running Termux:Widget icon on your homescreen to bring up the desired Activity.
Does this work for you to bring up the named Activity on Android with the only thing you know being the unique Activity name?
If so, here's what's left that I know of:
a. Figure out how to add a step to actually press the "Reset" button!
b. Figure out how to use a shortcut instead of an always-running widget (which can't be placed inside a homescreen folder)
c. Figure out how to run this automatically such as when there is a screen unlocking event.

Notes: Keep in mind the goal is to be able to interact with ANY known Android Activity using only freeware (so that everyone can do it); resetting the ad id is just one of the simplest examples.
Interested users can try this on the "Show Running Services" Activity (e.g., for implementing a "ps -aux|kill -9" shortcut).
