I am doing some testing and writing scripts in GScript and was wondering if there is a power off or shutdown command (as opposed to reboot). I want a command that will literally just turn the phone off but it needs to be a command line command, not an app.
Thanks
Code:
C:\>adb shell
* daemon not running. starting it now *
* daemon started successfully *
# which shutdown
which shutdown
/system/bin/shutdown
http://www.computerhope.com/unix/ushutdow.htm
lol i tried "shutdown -k" and it shutdown my phone!
Code:
# shutdown -k wait
shutdown -k wait
mount: mounting tmpfs on /dev failed: Device or resource busy
mount: mounting sysfs on /sys failed: Device or resource busy
mount: mounting none on /dev/cpuctl failed: Device or resource busy
C:\>
When I try shutdown from terminal it just locks the phone up completely

I too am trying to achieve phone power down using a script. But like you when I issue the shutdown command the phone immediately powers off and won't switch on again without a battery pull.
Same for reboot command.
I am using gscript lite and have s-off with a stock Froyo sense ROM.
"poweroff" generally works in linux systems. I haven't tried this in Android though.
"reboot -p"

Poweroff works if run using busybox, however, the command needs parameters to run.
#poweroff (doesn't work)
#busybox poweroff (also doesn't work)
#busybox poweroff -d 8 -f (works!!)
The -d 8 delays by 8 seconds to give system a chance to stop processes and unmount filesystems, whilst the -f forces poweroff.
Works a treat using Gscript. Not sure if it harms the system as the busybox poweroff command does not use init. That may be a bad thing. I just don't know enough about Android/Linux to know that. Maybe someone else does???
"reboot -p" works.
"busybox poweroff -d 8 -f" works too.
"busybox poweroff -f" works.
If I use the power button to shut down it takes a bit of time, goes through a process. If I shut down using terminal, by the command reboot -p, the shut down is instant. Is there any harm in that, or is that ok to shut down like that?
I like to find ways to reduce the use of the power button, as some have reported it fails after time, but if it's not good for the system then I'll just shut down normally using the power button...
YES! "reboot -p" works for me

"reboot -p" has a possibility of harming the phone.
What if none of these commands work for my device?
reboot does work.
reboot -p does not, just returns to command prompt.
shutdown does not work (no such file)
poweroff does not work (no such file)
busybox is installed, but these applets are not installed
Is there any other way?
"adb shell shutdown"

If you use adb:
"adb shell shutdown" - performs immediate shutdown
poweroff under su always worked for me.
Nothing works but reboot -p for abrupt shutdown on my phone..
It may cause harm

Sometimes there are problems when you use reboot -p too often, like failure in file systems because they are not unmounted safely. I do not use this command very often. I only use reboot recovery for flashing roms. Just try not to use this command very often to prevent harm okay?
Current Phone/ROM:
Samsung Galaxy Ace GT-S5830/Cyanogenmod 10.1 RC1 by bieltv3
Recovery:
CWM v5.0.2.6
ROMs used in the past: CM9 RC2 by Maclaw, SGS2 v9 ROM, AOSP ICS ROM by Maclaw, PAC ROM(very disappointed with this, no play store included.)
reboot -p actually does a reboot
Hi there,
on my device
Code:
reboot -p
does shut down the device, but after a few seconds (like 2 or 3 seconds) it boots again. So actually it behaves like doing a normal reboot. Any ideas how I can fix this issue?
Thank you and kind regards,
ToBe_HH
Hello gyus,
is there any Android application to perform power off?
Thank you
The followin shut down my CM13 using the Cerberus shell. Very slick.
su -c 'am broadcast android.intent.action.ACTION_SHUTDOWN && sleep 5 && reboot -p'

Hello,
I downloaded the latest version of busybox on my o4x, after I downloaded that, I turned off my device. When I tried to turn it back on, it got stuck on the 'loading apps' page, so I can't basicly do nothing with the phone. I let it load apps for like 10 hours (while on the charger) but that didn't work, and I let my phone run out of battery and after a couple of hours turn it back on, that also didn't work.
Does anyone know how to fix it, or can at least tell me what the problem is?!
Thanks,
Luuk
Try to clear dalvik cache, so that it gets rebuilt. Then try again. If you don't have CWM installed, you might as well be able to do it manually, but unfortunately I don't know the commands for that atm.

I had the same problem. You can start the P880 in stock recovery and connect it to pc. After the drivers are installed, you have access via adb. Because you installed busybox, i think your device is rooted. So you cann access your P880 with "adb shell", in the shell "su", then you have to mount system and you can push another busybox (e.q. from root, the o4xr directory contains a functionally busybox) to your phone (/system/xbin)
Just download o4xr.zip from the "How to Root" thread.
Then do the following:
- extract o4xr.zip and switch to that folder
- adb shell "su -c 'mount -o remount,rw -t ext4 /dev/block/mmcblk0p33 /system'"
- adb push busybox /sdcard/
- adb shell "su -c 'cat /sdcard/busybox > /data/local/busybox'"
- adb shell "su -c 'chmod 777 /data/local/busybox'"
- adb shell "su -c 'cat /sdcard/busybox > /system/xbin/busybox'"
- adb shell "su -c 'chmod 777 /system/xbin/busybox'"
- At this point the device will reboot itself automatically (Don't know why?), if not: adb shell 'su -c reboot'
- Delete /sdcard/busybox
- Done
I´ve done all this and its booting again with no problems....
Allright, it all sound really complicated to me. I will do my very best! But how exactly do I boot my phone in stock recovery mode, volume up and power button at the same time?

Vol- & Power. Vol+ & Power will bring you to "Emergency mode", this might work as well. Just make sure you have adb access.
Hello
Thanks for the guidance' the only thing is that "adb push busybox /sdcard/" is not recognized so I pushed the file into /temp I created and then continued accordingly

Normally u can push directly through /data/local without the /sdcard step. But its ok to push it to any other local tem-folder before moving it to /system/xbin...
Search for total commander the pc version and the adb plugin then you can access the phone file system, il post what next to do,
* total commander - http://www.ghisler.com/ - officall free version
adb plugin -- http://www.totalcmd.net/plugring/android_adb.html
---------- Post added at 03:53 PM ---------- Previous post was at 03:43 PM ----------
basically what you need to do is said in this extract from a previous post i had done
open total commander and then click configuration and then click options then next click the plugins tab followed by the the WFX button,
then point it at the installed adb plugin,
Once you have done that click the Drive tab in total commander it will be set a drive C:/ and change to Network Neighbourhood, now go to your phone and plug in your usb lead while powering it up and holding the power key and volume up and not releasing until it starts.
Now in total commander click adb in the explorer part and it access you into your phones file system so click on the root folder then click the system folder and then click the Xbin folder i replace the busybox inside with the busybox file which is in o4xr
Please
Hello,
Thanks for the support, but I don't understand anything from your post. I'm not a real geek, and know how all this stuff works, so my phone is still dead. Lg won't take it back for repair, and other phone companies can't manage to fix my phone. So can you please give me some more specific instructions, sorry that i'm a noob, but I miss my phone .
I only understood the 'download the onxr4 file and extract it', after that I lost it:silly:.

Try reflash the *.KDZ .
See this thread :-

Then boot into recovery [ (power on) + (vol-) ] .
Then wipe cache ,, and do factory resert . This will delete all your apps .

do the kdz flash. Easiest and safest. Worked for me with the same prob like you.
Did that
I already did that al long time ago, didn't work though. I'm considering to buy a new phone, I've been having these prpblems for several weeks now.

Why don't you just send it to LG for repair. They'll fix it for you and you'll get it back as good as new. And after you have done that, stop messing around with busybox.

Dude...
You are my man! I've got the problem solved, so thank you!!
Good morning guys,
I potentially have a couple of hundred of these to update with an AOSP ROM. I dont have any problems with the update, all smooth sailing, but I'm trying to script as much as possible to automated the process - Unlock bootloader, get root, push all the files then install the ROM.
For some reason though the command 'adb reboot recovery' doesn't work as expected. It just reboots the phone back to the normal OS.
Has anyone else encountered this? or a work around?
I can issue 'adb reboot-bootloader' and it will reboot into the bootloader correctly where I can issue fastboot commands but not to the recovery (Which is CWM latest as of today, which I think is 6.1.1?)
Thanks in advance!
Code:
adb shell
su
echo "boot-recovery" | /system/bin/dd of=/dev/block/mmcblk0p5 bs=1 count=13
reboot / reboot recovery

Your a genius.
As a side note this didn't require root access.

Maybe you can help me out a little futher. What I'm trying to do is automate the superuser install.
From the look of that, is that writing to one of the recovery commands located under /cache/recovery ? Perhaps the command file?
If it is or not, perhaps you know of a way to write the /cache/recover/command file to run an update ZIP immediately on rebooting into the recovery? My reading seems to be going in circles.
From my reading what I would need to do is:
* Copy the superuser.zip to the sdcard
* write 'boot-recovery' to 'a' file as you mentioned above
* write '--update_package=/sdcard/superuser.zip' to the file /cache/recovery/command
Obviously without root already I cant just write to that file so I thought it might be possible to use 'dd' as above?
Then rebooting into recovery should automatically run the update zip? Or am I mad?
You do need root to write into the command file. 'dd' tool also needs root.
Welcome to Flashe!:victory:
Flashe is basically an all-in-one installer which only requires a few clicks and you are root,unlocked(bootloader), and you can choose a recovery to install in the process. This is much easier than using ADB commands or fastboot.:good:
The program does included a feature that allows you to use a custom boot image and get rid of the "unlocked bootloader" screen.
WARNING: USE AT YOUR OWN RISK
Requirements:
-Atrix HD,Razr HD,Razr MAXX
- .bin logo file(rename to logo when put in flashe folder)
- .iso for your recovery(CWM,TWRP, or Philz)
Future Update:
-Downloads the required files from a server
-Menu(choose to install other things
-GUI, instead of text there is a actual button interface.
Errors:
You MUST allow the program to boot you into recovery otherwise the custom recovery is lost due to the android os overwriting it. If you have any other errors pm
me!

I looked at the threat, and it calls it a threat because it is a rooting tool.
Also,When I first started rooting I did not get how to use it at all(Mythtools).Instead I used programs on my android.So I made this to help new users coming to the atrix community once I finished learning ADB commands and some fastboot commands.
Here is the source:
Code:
adb kill-server
adb wait-for-device
adb push pwn /data/local/tmp/pwn
adb shell chmod 755 /data/local/tmp/pwn
adb push su /data/local/tmp/su
adb push busybox /data/local/tmp/busybox
adb install Superuser.apk
adb shell /data/local/tmp/pwn
adb shell rm /data/local/tmp/pwn
adb shell rm /data/local/tmp/su
adb shell rm /data/local/tmp/busybox
adb reboot
adb wait-for-device
adb push unlock /data/local/tmp
adb shell chmod 755 /data/local/tmp/unlock
adb shell su -c /data/local/tmp/unlock
adb shell rm /data/local/tmp/unlock
adb reboot bootloader
fastboot getvar all
fastboot continue
adb wait-for-device
adb reboot bootloader
echo [-] To continue you will need a boot file which will
echo [-] replace the "Unlocked Bootloader" image. Name it:
echo [-] logo.bin
echo [-] Continue when you are in the bootloader and have the file.
pause
fastboot flash logo logo.bin
fastboot continue
echo [-] Processe complete!
echo [-] -Root installed
echo [-] -Bootloader unlocked
echo [-] ---------------------
echo [-] This next step will install a recovery.
echo [-] Recovery will allow you to install your own roms,etc(depending on the selected recovery)
echo [-] Rename your recovery image "rec" so it should be 'rec.img' then continue.
pause
adb reboot bootloader
echo [-] Continue once in bootloader
pause
fastboot devices
fastboot flash recovery rec.img
echo [-] Once finished flashing continue...

adb reboot recovery
echo [-] Complete! You now should have recovery installed. Enjoy!

TL;DR: can someone direct me to a custom recovery image for droid bionic that lets me turn on developer mode USB from recovery mode? does CWM or TWRP do this?
Long version: i thought i could run a game that wasnt running well by installing the chainfire 3D mod. nope. it softbricked, and my developer usb mode was off at the time. now im stuck at a black screen after the M logo.
the device is rooted, running stock. (4.1.2). i plan on switching to a modded rom when i solve this and back my stuff up.
i can boot into fastboot, and the stock recovery mode. through recovery i can get an adb sideload mode to enable, and it does connect properly to PC, but normal ADB commands do not work. i also have options for bp modes and stuff when trying to boot to recovery, but most of those fail to start.
i know that if i can acesss normal ADB mode, fixing this is a couple simple commands away. there's an uninstall.sh file already there i just need to run.
fastboot and the sideload adb mode both function properly. my PC drivers seem to be in order for now.
if there's a file i can sideload or a command that works in adb sideload mode that will uninstall this driver, im all for it. ive already located the code used in the uninstaller:
Code:

sadly, i know very little about android and not much about linux. kind of picking this up as i go. im not even sure how to turn that code into an uninstaller file, though im guessing its as easy as a text file with the correct filename extension. i feel like i'm missing something sort of simple that someone more linux/android knowledgeable would be able to share.
can someone suggest, if one exists, an alternate recovery image i could install that would let me browse and edit files on the system partition, or enable full adb mode?
edit: i've tricked the device into charging, so the 'low battery' issue so many bionic softbrickers end up with has been avoided. phew.
edit 2: i used fastboot to reflash only system.img (i knew thats where the bad file was,) from cdma_targa_9.8.2O-72_VZW-22_cfc.xml.zip. the result was what appears to be a proper fix. i just lost a few tweaks (like deleting that godawful startup sound), and root. but i've rooted it before. shouldnt be a problem. next will be a full backup, and adb install of better recovery tools.
marking as solved.
