I just did a major mistake by copying sh from Windows to /system/bin/sh. Not haivng the execute bit has stopped me from using adb shell.
Could someone provide a clockworkmod recovery file that restores sh & it's permissions? I would greatly appreciate it. Thanks!
Why not just run the fix permissions script from the advanced menu in clockworkmod?

well, would be easier from a linux box:
chmod 755 sh
adb push sh /system/bin/sh
adb reboot

Thanks. I fixed it through recovery mode shell via adb.
I'm getting the following garbage when I do ls within adb shell. Is there any way to fix this?

Those are bash color escape codes but I don't know why adb is outputting them since I'm new to Android.
It's a windows command prompt thing..
Easiest solution, do this from your adb shell (you'll need to do it each time)
export LS_COLORS=none
alternatively you can installed cygwin and spend a little time setting it up so that the ANSI colors are displayed when using adb shell.
I assume the colors show up fine under linux, which is why this got included in some kernels/rom packages without anyone addressing it.
Thanks for the info. It shows up correctly through a cygwin terminal. I'll just use that for now on.
I'm trying to find an universal way to read userdata partition(dump partition) without rooting the device.
Assumption :
the device can be boot in fastboot mode
Possible ways :
1. Using fastboot
I've looked into fastboot.c, it taking usb as a usb_handle pointer. I'm trying to move from that point. Fastboot is mostly to write or erase, but I assumed if writing and erasing are possible, reading should be possible as well.
2. Using nvflash, tftp...
It won't be the solution, since it's chip dependent but using chip vendor's download tool to dump partitions.
Go for it!
How does using adb dumping from /dev/mmcblk0p1 sounds?
can I unmount mmcblk0p1, and mount back to readable position?
what device? more info please.
dd if=dev/mmcblk0p? of=data.img bs= 8096 is usually the easiest. (<--just an example)
also this may be helpful:

Thanks for the link. using dd command is the exact way I used to dump mmc block as root. Or can it be run under not-rooted phones?
Rooting depends on the kernel version of devices, so when I have to dump various phones, it's very cumbersome to root different kinds of devices and dump.
So I'm finding a way to walk around the problem by using fastboot or if possible adb.
I think fastboot is my best bet so far.
How about adb?

df -h

As already mentioned, dd, but via ADB. I believe that it functions at a low enough level that you should be able to dump mmcblk0 without having to be rooted. If dd can't be directly accessed via adb, you could extract a busybox install from a rooted phone and set it up in your adb directory and then run it from there with busybox (in theory).

Question.
Feels like i'm on the different page from you. If i run dd for /dev/mmcblk0 it does give me an error message saying "Access Denied" of couse mmcblk0 is owned by root. And busybox too(I haven;t tried this), it's just a set of linux commnads, I'm not sure how it can access a file(in this case, a device) which does not have its ownership.
Please correct me if I'm wrong.
Hi All,
There is a way to dump any partition to SD card partition on unrooted device vi ADB.
Paste this couple of lines into the terminal :
adb kill-server
adb wait-for-device
adb shell "echo ro.kernel.qemu=1 > /data/local.prop"
adb reboot
adb wait-for-device
adb shell "mount -wo remount rootfs /"
adb shell "rm /data/local.prop"
adb shell dd if=/dev/block/mmcblk0p1 of=/sdcard/mmcp1.dump
The phone may reboot many time after that, so make sure the file /data/local.prop is deleted after this operation. or execute this :
adb reboot
adb wait-for-device
adb shell "rm /data/local.prop"
adb reboot
hope that helps

Has anyone verified if this works for reading partitions on a non-rooted phone?
This doesn't work on an unrooted, locked device.
Code:
C:\Windows\System32>adb shell "echo ro.kernel.qemu=1 > /data/local.prop"
/system/bin/sh: can't create /data/local.prop: Permission denied
This did not work for my phone.
I got "permission denied" right after
adb shell "echo ro.kernel.qemu=1 > /data/local.prop"
Most of the above will only work on a rooted device with superuser.
The loop holes for shadow copies are mostly fixed since 6.0.
Partitions that can be accessed without root can be dumped with DD through ADB if ADB itself is supported and not internally limited to prevent just this.
Try
Code:
adb reboot recovery
adb root
adb shell
In my device, I can able to read those /data /dev without bootloader unlocking or root.

So, ... You are lucky. If I try these commands, I am getting "error: closed". And believe it or not, I have my bootloader UNlocked. It's a doomed chinese tablet, Allwinner 100 SOC.

I found that it is common for many Realme devices to able to use `adb root` in recovery mode.
I have a Realme C12 which has Mediatek Helio G35 MT6765G SoC. So we can also able to `readback` partitions by using SP Flash Tool with the help of MTK-bypass.

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.

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?

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.

@echo off

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.

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
adb kill-server
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.

and great script from user.
http://forum.xda-developers.com/showpost.php?p=55113422&postcount=208
will this work too on recovery or bootloops mode?
backup:
adb shell
su
mount -o remount,rw /system
cp /system/build.prop /system/build.prop.bak
mount -o ro,remount /system/ /system
----
restore:
adb shell
su
mount -o remount,rw /system
cp system/build.prop system/build.prop.bootloop
cp system/build.prop.bak system/build.prop
chmod 00644 system/build.prop
reboot
I build my own boot image for the Tolino Vision HD e-book reader (firmware 12.2.0, Android 4.4.2) just to enable adb on it. This went fine by setting the following lines in default.prop:
Code:
ro.secure=0
ro.adb.secure=0
ro.debuggable=1
persist.sys.usb.config=mass_storage,adb
persist.service.adb.enable=1
persist.service.debuggable=1
I'm able to run "adb shell", but am denied access to most directories, including /data/ and /system/.
Running "adb root" does not fail, but adbd is afterwards not running as root:
Code:
$ adb shell
[email protected]_6sl:/ $ id
uid=2000(shell) gid=2000(shell)
[email protected]_6sl:/ $ ps |grep adb
shell 2115 1 4592 212 ffffffff 00000000 S /sbin/adbd
$ adb root
restarting adbd as root
$ adb shell
[email protected]_6sl:/ $ id
uid=2000(shell) gid=2000(shell)
[email protected]_6sl:/ $ ps|grep adb
shell 3027 1 4588 208 ffffffff 00000000 S /sbin/adbd
What could be the reason for this behavior? I read that ro.debuggable allows adbd to become root, but that doesn't seem to be the case for my device.
----
Attached is a boot image for the Tolino Vision 4 HD with "adb root" enabled.
The most probable explanation is that adbd has been compiled without ALLOW_ADBD_ROOT.
tolino shine 2 HD
Hello Christian, your image runs like 'Schmitz Katze' on my tolino shine 2 HD. Maybe you should mention the link to your 'Tagebuch' here, since it's a nice manual (in English) or even open a tolino section here on xda. Tolino FW reverse stuff belongs (my opinion) here and not to all the German forums like ALLESebook, e-reader-forum, and others (thanks to all the guys there, who helped me to understand my tolino a bit).
You could mention in your 'Tagebuch' the option to try your boot.img with 'fastboot boot boot.img'.
Just scrcpy isn't running. I guess because of the 'adb reverse failed' error.
Code:
D:\aosp\scrcpy-win64-v1.10>scrcpy
INFO: scrcpy 1.10 <https://github.com/Genymobile/scrcpy>
D:\aosp\scrcpy-win64-v1.10\scrcpy-serv...shed. 1.3 MB/s (22546 bytes in 0.017s)
adb.exe: error: closed
ERROR: "adb reverse" returned with value 1
WARN: 'adb reverse' failed, fallback to 'adb forward'271
I'm writing this post by scrcpy, PC and my Redmi.
I managed to manually patch adbd on the Toloni Vision 4 HD and build my own boot image.
The process is described in a blog post: Getting ADB root access on a Tolino, which also has a link to download the boot image.
With it, "adb root" works and I was able to get access to all the files on the device. (File is also attached to the first post in this thread)
Alternative firmware (for almost all Tolino models)

i have that issue with minimal adb and fastboot
try using this ADB thread starter claims it's the newest ADB compiled
https://forum.xda-developers.com/android/general/tool-adb-fastboot-installer-tool-windows-t3999445
it might support "adb root" commands
