Hi to all.
I am trying to create an application for advanced boot options including the factory reset one, for rooted devices - mostly for Huawei devices.
My device is rooted, but when I try to perform a factory reset, it loads TWRP and I wipe the data manually -by choosing the desired wipes (the EMUI option for factory reset doesn't work - running android 6.0).
I have found a sample of code for this operation, but it doesn't seem to work:
Code:
try {
Runtime.getRuntime().exec(new String[] { "su", "-c","mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system/" });
Runtime.getRuntime().exec(new String[] { "su", "-c", "chmod 777 /system/" });
Runtime.getRuntime().exec(new String[] { "su", "-c", "recovery --wipe_data"});
} catch (IOException e) {
e.printStackTrace();
}
Does anyone know what exactly is the command that I need to use for this?
Thanks in advance.

Hello there,
Im trying to create my own file explorer (a very stripped down one) with root privileges just to learn how to code for android. Anyways, i am able to access my /system folder and look in every folder besides the /data folder. There are no subdirectories... its just empty. When i check through ADB or through terminal emulator, i can see al the folders in the /data folder. So what am i doing wrong???
I have this setup for now,
Code:
final Runtime runtime = Runtime.getRuntime();
try {
runtime.exec("su");
}
just go get root access, but i dont even know if thats correct. The app asks for root permissions and i can accept it but i still cant view the /data folder...
I also tried
Code:
runtime.exec("mount -o remount,ro -t yaffs2 /dev/block/mtdblock5 /data");
and
Code:
runtime.exec("mount -o remount,rw -t yaffs2 /dev/block/mtdblock5 /data");
and still nothing...

you don't actually have root
adb shell
Code:
# ls -l
drwxrwx--x 1 system system 2048 Jan 9 22:30 data
drwxr-xr-x 1 root root 2048 Jan 13 10:42 system
data is owned by system, and can only be read by system ( and root )
system is owned by root and can be read by everybody
you executed su
which got you root, but it didn't actually do anything, your app did not inherit root permissions

Hmmmm alright. Well what i can do to make my app inherit root permissions?
edit:
I was able to view the contents of /data by changing the permissions on the folder itself using:
Code:
runRootCommand("chmod 555 /data");
which would make it read-only and
Code:
runRootCommand("chmod 777 /data");
which would make it read/write (i think, maybe 755?)
where runRootCommand is :
Code:
public static boolean runRootCommand(String command) {
Process process = null;
DataOutputStream os = null;
try {
process = Runtime.getRuntime().exec("su");
os = new DataOutputStream(process.getOutputStream());
os.writeBytes(command+"\n");
os.writeBytes("exit\n");
os.flush();
process.waitFor();
} catch (Exception e) {
Log.d("*** DEBUG ***", "Unexpected error - Here is what I know: "+e.getMessage());
return false;
}
finally {
try {
if (os != null) {
os.close();
}
process.destroy();
} catch (Exception e) {
// nothing
}
}
return true;
}

Hello!
I need to set the system time!
What i read up to now is, that it is not possible! because it needs sec. level 3 (only System and Signed)....
I tryed it with:
Runtime rt=Runtime.getRuntime();
rt.exec("su");
rt.exec("date -s 19991212"); //And other sytax..
on the Tablet with ConnectBot its working, because connectBot was installed on the ROM!
The App i am writing is for internal use in my company, and it needs to sync with a Server!
My Tablet (Flytouch 3, Android 2.2) is rooted, so it should be possible to set the time! The App ClockSync (http://forum.xda-developers.com/showthread.php?t=688177) can do it too!
Please help me!
Thanks
Does it have to do so using root, or would launching an Intent to the system settings app be sufficient?
Setting Intend would be not an option!
but for everyone who is looking for a soution found one! (here on XDA (where else? ) http://forum.xda-developers.com/showthread.php?p=4528387#post4528387
calling:runRootCommand("date -s <date&time>");
Code:
public static boolean runRootCommand(String command) {
Process process = null;
DataOutputStream os = null;
try {
process = Runtime.getRuntime().exec("su");
os = new DataOutputStream(process.getOutputStream());
os.writeBytes(command+"\n");
os.writeBytes("exit\n");
os.flush();
process.waitFor();
} catch (Exception e) {
Log.d("*** DEBUG ***", "Unexpected error - Here is what I know: "+e.getMessage());
return false;
}
finally {
try {
if (os != null) {
os.close();
}
process.destroy();
} catch (Exception e) {
// nothing
}
}
return true;
}
just for ur information because i was looking for the syntax to set the date and time for about 2hours now, could find it in the inet :/
and finally i found it by hacking a lot of possible combinations in the terminal! and it is:
date -s yyymmdd.hhmmss
Example: 20110717.175930
I have a huawei u8950d which I wanna root.
Its bootloader has been locked but I found a way to root a locked device: http://forum.xda-developers.com/showthread.php?t=1461736
So I've make those following codes to a bat file:
Code:
adb push mempodroid /data/local/tmp
adb push su /data/local/tmp
adb push Superuser.apk /data/local/tmp
adb shell
cd /data/local/tmp
chmod 777 ./mempodroid
./mempodroid 0xd524 0xab8f sh
[COLOR="red"]mount -o remount,rw -t ext4 /dev/block/mmcblk0p17 /system[/COLOR]
cat /data/local/tmp/su > /system/xbin/su
chown 0.0 /system/xbin/su
chmod 06755 /system/xbin/su
cat /data/local/tmp/Superuser.apk >/system/app/Superuser.apk
chown 0644 /system/app/Superuser.apk
When launching the red line I got this:
Code:
mount: Operation not permitted
Is it the issue of mempodroid?
The two addresses doesn't match my device.
Code:
./mempodroid 0x**** 0x**** sh
Maybe other reason?
I need help.Thx!

Hi,
Were you finally able to root the Huawei U8950D? How did you do it? I will be grateful if you give me a step by step process. Thanks

what is this code and who we have to use it????
device: Galaxy S7 Exynos, systemless SuperSu, CF-Autoroot, Nougat 7.0
Hi,
I've tried a lot of things now, but I'am failing at editing a file in android /sys folder. I want to change a variable for battery charging in /sys/class/power_supply/battery/batt_tune_float_voltage. In a terminal I've performed following
Code:
1|herolte:/sys/class/power_supply/battery # cat batt_tune_float_voltage
43500
herolte:/sys/class/power_supply/battery # chmod 777 batt_tune_float_voltage
herolte:/sys/class/power_supply/battery # echo 42000 > batt_tune_float_voltage
1|herolte:/sys/class/power_supply/battery # cat batt_tune_float_voltage
43500
I even cannot mount battery_tune_float_voltage
Code:
1|herolte:/sys/class/power_supply/battery # mount -o rw,remount /sys
herolte:/sys/class/power_supply/battery # mount -o rw,remount batt_tune_float_voltage
mount: 'batt_tune_float_voltage' not in /proc/mounts
Does anyone know what the problem here is?! I would be really glad if someone could explain me if i've missed something or why this does not work.
Anyway: As I'am understanding so far, the App Battery Charge Limit here on xda uses following code for editing file /sys/class/power_supply/battery/batt_slate_mode
Code Link
Code:
val switchCommands = arrayOf("mount -o rw,remount $file", "echo \"$newState\" > $file")
if (alwaysWrite) {
suShell.addCommand(switchCommands)
} else {
suShell.addCommand("cat $file", 0) { _, _, output ->
if (output[0] != newState) {
setChangePending()
suShell.addCommand(switchCommands)
}
}
}
}
