[Q] Install busybox

Anyone knows how to install busybox?
I've tried to follow some guides but ends up with:
Code:
215:Desktop ricardo$ adb push busybox /data/local
580 KB/s (1083568 bytes in 1.823s)
215:Desktop ricardo$ adb shell
$ su
# cd /system/xbin
# mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
# cat /data/local/busybox > busybox
cannot create busybox: not enough memory
or
$ su
# cd /data/local
# mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
# dd if=/data/local/busybox of=/system/xbin/busybox
/system/xbin/busybox: cannot open for write: Out of memory
or
$ su
# cd /data/local
# mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
# ./busybox cp /data/local/busybox /system/xbin
cp: can't create '/system/xbin/busybox': Cannot allocate memory

same here. cannot write to rw-mounted /system.
sucks

Try my zip file. Woked for me
The only thing that I want to change and I can't is the init.rc file. I tried to mount the / (rootfs) with rw, but every time I restart my device the file is copied, again, from the ramdisk image.

I have the same problem

What should I do with your files?
Nobody has a solution to this?

I don't think this is a memory issue though, .. added 512mb swap and still it claimed to be out of memory, ..
also I figured maybe hd space .. however when i ln /data/local/tmp/busybox to /system/xbin it had the same error.
I both tried ln from the system and ln from busybox both had same result.

It's not a memory problem! In order to install it you have to be in recovery mode.
Try:
While in recovery mode use adb to connect to our phone. Now transfer the zip file (busybox.zip) to your phone and install it via clockwork recovery -> install zip file -> select my zip file.

can anyone post the proper busybox file cause for some reason the file signature verification failed.
adb push busybox-signed.zip /sdcard/busybox-signed.zip
rebooted phone held down volume button while booting ..
choose recovery, ..
choose install zip from sdcard..
then i see a lot of no and one yes .. so i choose yes but the installation is aborted.

Just install titanium backup and click on 'problems?' at the bottom. It will install BusyBox for you.

it has error during installation at line 4 with your busybox.zip
somethinf like can not chmod
(rooted buzz with stock rom)

Do what this guy said.

titanium install in /sdcard busybox, not in /system/bin (xbin) , so it is not usuable by other apps

i have installed it in during recovery mode in /system/xbin
how now to specify PATH for using commands from it?

i think you need to create aliases however why install it in xbin anyways then, .. if you need to create aliases or links in bin.. ?
example
$ ln -s /data/local/tmp/busybox ls
$ ./ls
if it is in a path that is included in PATH executing a command will auto look for it in all directories defined in PATH env so basicly you could just create all the directories under /data/local/tmp/bin
and just then append that to PATH env echo $PATH then append :/data/local/tmp/bin to it and busybox should work as well.

titanium backup is free software... look on the market, there's a free version and a donate version.

i have aliases in /system/xbin
they was created after busybox --instal -s
but in system allready exists some commands like ls => i want to use ls from busbox, not from system
and terminal emulator dont anderstand ^[ likes bindings

is there a definitive way to do this. There seems to be no clear way of doing it.

To install:
1) extract and push busybox to your sdcard, reboot into recovery
2) mount /system
3) if you don't have /system/xbin (you should), create it
adb shell:
# mkdir /system/xbin (if necessary)
dd if=/sdcard/busybox of=/system/xbin/busybox
cd /system/xbin
chmod 755 busybox
./busybox --install .
4) reboot and done
OPTIONAL - before rebooting replace the busybox installed by the root process in /system/bin
1) mv /system/bin/busybox /system/bin/busybox.bak
2) cp /system/xbin/busybox /system/bin/busybox

The above is pretty straightforward. The only thing is you need to download the zip in the other thread and 'busybox' refers to the binary in the zip rather than the whole directory - as I understand it. Correct me if I am wrong but trying the dd command on the dir will not work.

You dont have to extract the binary into a folder, just extract the busybox file direct on your sdcard. Than the dd command should work, on my phone it works fine.
But if not, does the command cat in the adb shell work?
If so, try istead of the dd comand:
Code:
mount /sdcard
cat /sdcard/busybox > /system/xbin/busybox
And remember to start your wildfire in the recovery mode, that was the mistake I had done...

How to root manually/without Windows

There is already an excellent write-up on how to use SuperOneClick to root your Optimus V.
Unfortunately, you may not have a Windows machine available to run the util, or your PC hates the LG drivers, or you may wish to control how you go about rooting your device.
Hence this short write-up which, obviously, relies on pieces I got from that other write-up.
I. Rooting your device
1. You still need ADB!
2. Download the LG Optimus V Tools package from http://nexus.zteo.com/projects/tools/
3. Unzip it
4. Command-line:
Code:
adb push psneuter /data/local/tmp/
adb push su /data/local/tmp/
adb shell
cd /data/local/tmp
chmod 777 psneuter
chmod 777 su
./psneuter
5. You should be kicked out of the shell
6. Command-line:
Code:
adb shell
mount -o remount,rw -t yaffs2 /dev/block/mtdblock5 /system
cat /data/local/tmp/su > /system/bin/su
mount -o remount,ro -t yaffs2 /dev/block/mtdblock5 /system
(Oh look you are root!)
That's it. You now have permanent root access.
After rebooting your phone, adb should be back to logging you in as a regular user but typing "su" will do the trick.
Note: I realize that the version of SuperUser.apk that comes with SuperOneClick might be re-usable here. I haven't had any success with it but you may.
II. Flashing a new ROM
1. After rooting your device, obviously...
2. Get an image for the ROM you wish to flash...
Currently, my favourite one is a fairly recent version of Zefie's CM7.
You can find it by googling "update-cm-7-04282011-NIGHTLY-thunderc-Xionia-signed.zip" -- I will refer to it, below, as <your_rom_zip_file>
3. Get a minimum Google Apps package for flashing as well.
Here, I would google "gapps-gb-20110325-signed.zip" -- I will refer to it, below, as <your_gapps_zip_file>
3. Command-line:
Code:
adb push flash_recovery /data/local/tmp/
adb push recovery.img /sdcard/
adb push Debug-FormatSYSTEM.zip /sdcard/
adb push <your_rom_zip_file> /sdcard/
adb push <your_gapps_zip_file> /sdcard/
adb shell
su
chmod 777 /data/local/tmp/flash_recovery
/data/local/tmp/flash_recovery /sdcard/recovery.img
reboot recovery
4. In recovery: Flash Debug-FormatSYSTEM.zip
5. In recovery: Wipe cache and dalvik-cache
6. In recovery: Flash <your_rom_zip_file> -- this will take a while
7. Do not reboot!
8. In recovery: Flash <your_gapps_zip_file>
9. Now, reboot.
10. Let your phone think about life for a few minutes
11. Select "Skip" when your phone asks you to create/enter your account info
12. Launch the market; now, enter your main account information

Hey first of all let me tell you that I appreciate this guide. Now my problem is that I am such a noob that I may be doing this wrong.I download the file to my optimus.Then in an explorer I extract it, correct? After that once I put in the first line of command on terminal emulator I get an error that says "adb: permission denied". Please help this guide is my last resort.Whatever I do I can not root through windows.It would be nice if you could explain in more detail every step. Thanks!

help
can u please add a little more detail thank u very much appreciated.

SouthParkFan15:
adb is a tool that you run on your computer; it is available for Windows, Mac OS X and Linux. It is part of the Google SDK.
thizizjohnny:
Could you give me a little more detail regarding what detail you are interested in?

How do I unzip?.. is extract the same thing? I'm running Linux mint 10. How do I get adb? Excuse my noobness.
Sent from my VM670 using XDA App

Oh and one last thing.. does this work on android version 2.2.1?
Sent from my VM670 using XDA App

Yes this works with 2.2.1.
On Linux Mint, you can use the package manager or the unzip command in a terminal window.
apk:
Download the SDK at http://developer.android.com/sdk/index.html
Install it, then run "android" and select "Install platform tools"

I finally got adb on my system, but when I type in "adb devices" nothing comes up and when I do any command that involves the phone i get "error:device not found".Yes I have usb debugging on and yes I have all the right drivers installed and yes I have tried rebooting a million times, and no my computer has never recognized my phone the way it should.Let me also point out that though pdanet or droid explorer they can't find my device. Help please I'm desperate!

Oh, my. Sorry to read that.
Problem is, in 2.2.x, the exploits that give you root access rely on ADB itself so you couldn't be more out of luck.
On second thought...this may seem a bit weird but there may be a way. I have to think about it. It would involve using a file manager that agrees to "see" /data/local/tmp, running psneuter from there and keeping our fingers crossed. I'll keep you updated.

Alright thanks cyansmoke! Keep me informed.

I ran all of the steps for rooting and I didn't get one error. It didn't seem to work though. When I launch adb again after rebooting my phone I get permission denied when I try to run su.
Here is the cap from my command line. I have no idea why it didn't take.
C:\phone\LGOptimusVTools>adb shell
$ cd /data/local/tmp
cd /data/local/tmp
$ chmod 777 psneuter
chmod 777 psneuter
$ chmod 777 su
chmod 777 su
$ ./psneuter
./psneuter
property service neutered.
killing adbd. (should restart in a second or two)
C:\phone\LGOptimusVTools>adb shell
# mount -o remount,rw -t yaffs2 /dev/block/mtdblock5 /system
mount -o remount,rw -t yaffs2 /dev/block/mtdblock5 /system
# cat /data/local/tmp/su > /system/bin/su
cat /data/local/tmp/su > /system/bin/su
# mount -o remount,ro -t yaffs2 /dev/block/mtdblock5 /system
mount -o remount,ro -t yaffs2 /dev/block/mtdblock5 /system
# exit
exit
C:\phone\LGOptimusVTools>adb shell
$ su
su
su: permission denied
$

It's possible that you have another su in your path that takes precedence.
Please try typing:
/system/bin/su

Hey, do you know if there is a way to upgrade my device to froyo 2.2.2? It's currently 2.2.1 and whenever I go to update system it says something like "Your system is up to date".Incase you have forgotten I have the optimus v that can't establish connections with the computer.So what I could do?I'm thinking that If I do that then maybe it could fix all of my problems (or some of them).Thanks

I don't think that it will help you no.
OK it's taking longer than I thought because my wife's LGV, after I restored it to stock, decided that it would not allow psneuter anymore.
Thus, I will need you to run these commands for me and let me know how that went:
1. First, copy psneuter to the root of your SD Card.
2. Then, download Terminal Emulator from the market
3. Run Terminal Emulator, type:
Code:
cp /sdcard/psneuter /data/local/tmp/
chmod 777 /data/local/tmp/psneuter
/data/local/tmp/psneuter
Now, if we are lucky, you should get kicked out of the terminal app (I know it's weird but there is a claim that it goes through adb(!))
Restart the terminal emulator. If we are double-lucky, your prompt should have changed from '$' to '#'
Fingers crossed. Still surprised to hear that terminal emulator would go through adb. No, let me rephrase that: I am moderately surprised, in fact, considering the limitations put on non-rooted apps.

After I put psneuter on the root of my sdcard.I go to terminal emulator and put in the first code and it says "cp: permission denied".Any suggestions?

Ah, my bad, no "cp" by default.
New instructions:
Code:
cat /sdcard/psneuter > /data/local/tmp/
chmod 777 /data/local/tmp/psneuter
/data/local/tmp/psneuter

After I put in the first code I get an error message saying "cannot create /data/local/tmp/: is a directory".

*facepalm*
Of course I should have written:
Code:
cat /sdcard/psneuter > /data/local/tmp/psneuter

I put in "cat /sdcard/psneuter > /data/local/tmp/psneuter" and I get an error message saying "cannot create /data/local/tmp/psneuter: directory nonexistent".

Any suggestions?

[ROOT ICS] The hard way && Digging for roots

For anyone that doesn't want to root the hard way crossix has come up with a double click root for Windows forum.xda-developers.com/showpost.php?p=23052186&postcount=105
Update 2/26/12
/system can now be mounted writable see the bottom of this post.
So the old Honeycomb exploit has now been patched in ICS. But there was an exploit found in the newer ICS kernels. Written by saurik,: called mempodroid
There is an offset needed as an argument to the binary, for the a100 we'll use what has worked for the a200 as noted in sauriks github linked above.
The issue with this is mounting /system as writable. I'm not sure if it's something in ICS, but it appears to be write protected. As noted here and here we will loop mount the system partition.
The tools needed are:
1. mempodroid under Usage Instructions, download pre-compiled
2. busybox 1.20 snapshot 3-10-12
3. su the latest from androidsu.com, extract from system/bin
4. mount.txt script
After downloading and extracting place them all in a folder called tools.
This must be done with adb. Issue the following from cmd or a terminal:
Code:
$ adb shell mkdir /data/local/tools
$ adb push tools /data/local/tools ; adb shell
$ cd /data/local ; chmod 755 tools/*
$ cd tools ; ./mempodroid 0xd9f0 0xaf47 sh
If all went well you should be at a hash # prompt. This is temp root.
mount /system rw the new way:
Code:
# PATH=$PWD:$PATH
# sh mount.txt -o remount,rw /system
Copy su and busybox to /system
Code:
# ./busybox cp busybox /system/xbin; ./busybox cp su /system/xbin/
# chmod 6755 /system/xbin/su
Install busybox
Code:
# cd /system/xbin
# for i in $(busybox --list); do ln -s busybox $i; done; sync
Copy the mount script
If busybox is updated this step must be run again
Code:
# cp /data/local/tools/mount.txt /system/bin/mount
# cp /data/local/tools/mount.txt /system/xbin/mount
Done your a100 should be rooted
the old way:
Now lets loop mount /system
Code:
[b]This is no longer needed[/b]
# ./busybox losetup -o $((512 * 51200)) /dev/block/loop7 /dev/block/mmcblk0
Code:
# ./busybox losetup /dev/block/loop7 /dev/block/mmcblk0p3
# mkdir loop ; mount -t ext4 /dev/block/loop7 loop
Copy su and busybox to the new mount point.
Code:
# ./busybox cp su loop/xbin/ ; ./busybox cp busybox loop/xbin/
# chmod 6755 loop/xbin/su ; sync
If it worked your a100 is fully rooted. Make sure to install SuperUser from the Market.
Either get busybox installer from the market, and install it to /data/local/tools/loop/xbin
Or:
Code:
# cd loop/xbin
# for i in $(busybox --list); do ln -s busybox $i; done; sync
The mount point won't survive a reboot so in order to write to /system again run:
Code:
# busybox losetup /dev/block/loop7 /dev/block/mmcblk0p3
# mount -t ext4 /dev/block/loop7 /data/local/tools/loop
[update 2/26/12]
To mount /system as writable do the following from adb. We'll just make a directory called /data/loop for easy access.
Code:
$ adb shell
$ su
# stop
[b]your screen will go black[/b]
# mkdir /data/loop
[b]skip this if the loop is already set up
# busybox losetup /dev/block/loop7 /dev/block/mmcblk0p3[/b]
# mount -t ext4 /dev/block/loop7 /data/loop
# mount -o bind /data/loop /system
# start
You can write to /system with any app but /system can't be remounted ro then back to rw.
This can be added to /etc/install-recovery.sh to make it permanent
Code:
busybox losetup /dev/block/loop7 /dev/block/mmcblk0p3
mount /dev/block/loop7 /data/loop
mount -o bind /data/loop /system
Thanks to crossix as the first to get temp root, and Icewyng for pointing out the exploit and helping with the magic number.

Ill be testing this when I get home, if it works Ill attempt to write a 1 command script to do it.

OK...
Testing this out and found there were a couple of bugs.
You didn't have a "loop" folder created so I made one in the "tools" folder.
and, when mounting, you need to specify -t ext4.
Here are the revised commands for # mount /dev/block/loop7 loop
mkdir loop;mount -t ext4 /dev/block/loop7 /data/local/tools/loop
I noticed that the files /data/local/tools/loop/xbin/su and /data/local/tools/loop/xbin/busybox don't exist on /system/xbin until after a restart.
Finally, the busybox we are using to install doesn't seem to make all of the links to all of the nice commands we are used to, so things like grep, cp, etc... they won't work. I'm trying to figure out how to re-run the GUI busybox installer and point it to the loop folder, but haven't had much success.

You beat me to the punch... was about to point it out.
Not sure what version of busybox this is but I will try with 1.19.2 and see how it goes.
Edit: Got root! It works great... for Busybox, use Busybox Installer to be able to get the latest version (1.19.4) I confirm that system is R/O for now.

I did have some typos, think it's right now. That is an old busybox, it was just a quick find and it includes losetup but it's not one to use full time. Maybe sync is needed at the end so files are written properly. I didn't have to use -t ext4 with HC, but Ill add it to the OP
[edit] you have to use "busybox cp or busybox grep" I didn't include a way to add all the symlinks. Wow I have typos everywhere it's the end of the day for me, working nights.

Ok ... Got root!
Titanium works, Busybox Installer works, Superuser works, Root Explorer works...
Only thing is that System is R/O but we will work on it.

Waiting for a R/W system...and then, no one will stop my update

I can't get it to root :-(

At what point, need some more details.

The tools folder gets pushed (the 3 files are copied) but then it says there is no such folder.
edit: never mind - i created the folder manually and pushed the files into the folder
edit2: rooted - thakns guys

Brilliat work, will try this later (need to get the sdk all set up again, I've been distro swapping). Got a pool match tonight too, so will try as soon as I can, will give whatever feedback I can later.

I forgot adb can't push a whole directory, it instead only copies the files within the directory.

wait how is it rooted if it's r/o I thought point of root was to make the file system r/w... er is root just allowing you to view all directories? Sorry for a noobish question, but you gotta start somewhere right?

Well I think if we have su working we will be able to mount /system rw in some way if not directly. I cant imagine not being able to.
In any case though being able to write to /data as root is very useful. Example: Hulu flash fix.

You can't view /data if you're not root. That's one thig. Also, other functions may require root, like advanced networking things, etc.
I agree, not being able to write to /system is a major inconvenience, but most of the root programs will still work, as long as you're not writing to /system.

Since this is a temp root, does it mean that I will have to reroot every time I reboot? Will apps like Adfree work on this?

better yet is there a way we can do this solely on the tab? im away for work for another 4 weeks and only have my cell and a100 with me :-(

The first line may produce
losetup: /dev/block/loop7: No such device or address
If it's not looped
After you are rooted the above can be run without adb from a terminal as su.
The mount point can be anywhere ex. /sdcard/loop instead of /data/local/tools/loop

[Q] Run script on FireTV boot

I have a very simple script to mount my NAS to a specific path that I want executed every time my FireTV boots.
I have read about pointing to it in the install-recovery-2.sh, however that is not available on my FireTV. I have also read about placing the script in system/etc/init.d/ however that path doesn't exist on the fireTV either.
Would prefer to do this at the system level and not rely on a manager (Tasker, Script Manager, etc).
Anyone have any experience?
Update w/ solution:
I was able to get this working by placing a script called install-recovery.sh in /system/etc/ . Make sure that permissions are set appropriately (at least 755). If creating the script on a Windows machine, make sure there aren't any hidden whitespace characters (I personally verified the script using SManager on my Fire TV).
Code:
[B]sleep 15[/B]
mkdir /mnt/obb/nas
chmod 777 /mnt/obb/nas
[B]sleep 20[/B]
mount -o noperm,unc=\\\\192.168.1.147\\Public,username=xxxxxx,password=xxxxxx -t cifs none /mnt/obb/nas
The sleep command is necessary as the script may run before the network is initialized.
Thanks rbox and ECEXCURSION!

I have read about pointing to it in the install-recovery-2.sh, however that is not available on my FireTV. I have also read about placing the script in system/etc/init.d/ however that path doesn't exist on the fireTV either.
Would prefer to do this at the system level and not rely on a manager (Tasker, Script Manager, etc).
Anyone have any experience?

Ahh, sorry a little dense
Will give that a shot and report back on the results

Ok, I have placed install-recovery.sh (which houses my mounting script) in /system/etc/
I reboot and it doesn't appear that the script has run. Is there anything else I would need to do in order to get it to run on boot?
If it matters here are the details on my FireTV
Custom Recovery 6.0.5.1.4a
Pre-rooted 51.1.4.1_514013920

That is a very good question How can I test that my script is functioning?
From adb shell or Terminal emulator I type the following commands to mount my NAS:
Code:
su
cd /mnt/obb/
mkdir nas
chmod 777 nas
mount -o noperm,unc=\\\\192.168.1.147\\Public,username=xxxxxx,password=xxxxxx -t cifs none /mnt/obb/nas
To turn this into a script I just dumped it into notepad and added #!/system/bin/sh to the top and saved it as install-recovery.sh.

Run it from adb, but right off the bat, I can tell you you need to chmod 755 it atleast before that will work.

Well first of all, don't run it with sh... it needs to have #!/system/bin/sh at the top, and you need to run it directly. Second, don't put su in it because it's already running in the root context.

How would I run it directly?
Here is my current script (with su removed):
Code:
#!/system/bin/sh
cd /mnt/obb/
mkdir nas
chmod 777 nas
mount -o noperm,unc=\\\\192.168.1.147\\Public,username=xxxxxx,password=xxxxxx -t cifs none /mnt/obb/nas

I am attempting to run that in adb shell, but am getting the following errors:
Code:

It seems like the permissions are correct on the file, and I also tried adding ./ before the path to see if that made any differences.
I made a slight "upgrade" to my script to see if it would help (but as you can probably already see, I am not exactly sure what I am doing!):
Code:
#!/system/bin/sh
mkdir /mnt/obb/nas
chmod 777 /mnt/obb/nas
busybox mount -o noperm,unc=\\\\192.168.1.147\\Public,username=xxxxxx,password=xxxxxx -t cifs none /mnt/obb/nas

That sounds strange... but you'll need to run su before running it, because it needs root. It could be that its not in UNIX file format. If you edited it on Windows you need to use an advanced editor that has the ability to save as UNIX format.

Unix file format appears to have been the issue. When I opened it with SManager I saw some nasty whitespace characters. Removed those and the script works as expected:
Code:
[email protected]:/data/media/0 # ./install-recovery.sh
./install-recovery.sh
[email protected]:/data/media/0 # cd /mnt/obb/nas
cd /mnt/obb/nas
[email protected]:/mnt/obb/nas # ls
ls
Games
Photos
Shared Music
Shared Videos
eBooks
key.txt
[email protected]:/mnt/obb/nas #
After confirming the script worked as expected, I moved it to /system/etc/ and verified permissions were acceptable (777). Upon reboot I see that the /mnt/obb/nas is created, however the NAS is not mapped.
Can you comment, when is the install-recovery.sh called in the boot up process? Is it possible that the CIFS module isn't fully loaded when this is called? Alternatively, is there a log that I could reference to see if any error occurred while running the script at startup?

It's probably running before the network comes up. There might be maybe some kind of regular android apk that will run a script when the network comes up. There might be a way to just stick a loop in your current script waiting for something, not sure.

You could probably just add "sleep 30" to the beginning of the script.

Thanks, will give that a try when I get back home.
Edit: It worked! Thanks to the both you for your input.

Just wondering since I'm a newbie when it comes to this one. Does mounted folder have to be in /mnt/obb or can I choose any directory I want?

help me please I cannot modify system files despite having root

i'm on (pixel 2xl) lineageos 16.0 rooted with magisk, i want to add a script in init.d folder but i can't do it, i tried with root explorer but it doesn't work, afwall also can't mount folder for startup script, any solution?

Why? What error do you get?
Try to move/copy something into /tmp folder. It should work if you're rooted (your shell shows # instead of $).
If it doesn't work, maybe you have to remount your system as rw (read and write):
Code:
mount -o rw,remount /
after you made your modifications, mount it as ro (read only) again:
Code:
mount -o ro,remount /
If it still doesn't work, we need to see the error you get (copy and paste into this forum) while moving/coping something into /tmp.

Can you verify you entered that command as root?
Please do the following:
Do this on your computer to enter your devices shell
Code:
prompt_PC:~$ adb shell
Code:
prompt:~$ whoami
This should give you either "shell" or "root"
If it says "shell" do:
Code:
prompt:~$ su
prompt:~#
It will show a # instead of $ if you're root.
If you're already root (or you are now root due to su command), do:
Code:
prompt:~# mount -o rw,remount /
Now it should be writeable and you can do your modifications.
After you finished you need to change it to ro (read only) again:
Code:
prompt:~# mount -o ro,remount /
After that you can exit the shell:
Code:
prompt:~# exit
prompt:~$ exit
(first exits su, second exits shell)
I'm sorry if you already did that but I wan't to be sure you did it correctly.
If this procedere doesn't work, please copy and past your input and output into this forum as this might help to understand what's going on/failing etc.
