No CP command in Dev Magic

I've been messing around with my Dev Magic and found a site for the G1 with some stuff to try:
http://gettinthru.blogspot.com/2009/04/mods-for-tmobile-g1-at-your-own-risk.html
In there, some of the things suggested use the linux command "cp" to copy files from/to the SD card. Problem is, I can't see it listed. Here is the listing of commands in /system/bin:

As you can see, no cp. Any suggestions like a .apk of the command to push over to it?
Cheers

you can use dd to copy files aslong as you dont have busybox ( on the dream "all" the rooted images come with busybox )...
However you can use busybox from a non-rooted device by copying it to the folder "sqlite_stmt_journals" as it has both exec/write rights...

Seem to be sorted now...
I found that I can install Busybox like the G1 owners have as standard:
http://www.androidfanatic.com/cms/community-forums.html?func=view&id=228&catid=9
Folowed the guide and have cp and loads of stuff to play with now.
Cheers for your responses.

No problem... Wont take long before custom images are put together that include busybox as the magic now can also be rooted like the dream.

the "rootme" rom i provide in my rooting procedure has busybox installed, as well as apps2sd

the easiest way to replace the "cp" command is using "cat"
cat "sourcefile" > "targetfile"
if you need to copy more files, create a small script with a "for" loop.

Optware for Android, another try

If you're interested in running more complete Unix/Linux environment on your Android device, you might have heard about Optware for Android, here is thread for example.
Well, that project had few issues, like: shipping binaries of unknown origin and running them on user's device as root; coded and advertised as applying to one particular device; making too much changes on the device in one turn (like alter rootfs image).
That's why I decided to create another Optware install script to address those points. It is explicitly envisioned to support Android as an OS/Platform, i.e. all devices, not one particular model. Well, that may be not exactly easy, but that's at least good aim to pursue. It also doesn't come with any random binaries, but instead downloads them from a trusted source during the installation process (sources being Optware itself for bootstrap packages and CodeSourcery toolchain package for libc on which Optware depends).
Due to the last point, the installation script runs on a Linux host, so ADB connection to the device is required. Device also should have working "su" command (i.e. be rooted).
The source code is on github: https://github.com/pfalcon/optware-android
Just a bit of DISCLAIMER: you should run this script only if you understand what Optware is, and how to use it. Some experience with Unix/Linux command line and shell scripts is required, in particular you should skim thru the install script before running it.
Otherwise, it works quite well on my Nook Tablet, and I'd be happy to receive suggestions, success/bug reports, patches, etc.

Great work.
I took the liberty of using your script as a base to install OpenSSH. Should work on any device. I can't post links so I attached an archive with the script and the necessary files.
CyanogenMod on my Touchpad has some sort of sysinit '/etc/init.d', so I initialize Optware and Optware init scripts from there. I don't know how other mods handle this, probably different. SSH authentication is key-based, since passwords are not set. Have a look at the script to figure out how to deal with that.

Glad it was useful for you. Issue how to automatically start up daemons on Android indeed exists. The native Android way is /init.rc config file (of adhoc format). The problem is that this file is located on rootfs, which is ramdisk, i.e. any changes are lost and not available during boot. And initial content of that ramdisk comes from initramfs/initrd, but it has many ways to be implemented - compiled into kernel or on separate partition, checksumed against any changes, etc. So, in general case it's not possible to update, and even if it is, a mistake can lead to bricked device.
So, I for now skipped that issue altogether in my installer, but hope to get to it eventually (have some ideas).
So, if you have CyanogenMod, then using /etc/init.d is for sure a good solution.

One suggestion/question... is it possible to alter the script to run directly off of the device's command line? That would eliminate the Linux (and optionally would eliminate the ADB requirement).
I'm sure there's a static wget binary for ARM already compiled somewhere, and the rest can be done through busybox.
That would really make it universal. I'm a Windows user, and haven't had the time to parse out your script and figure out what the end result is supposed to look like on the device

There's now FAQ at http://sf.net/p/optware-android which discusses why this isn't possible on pristine Android system (lack of basic POSIX utilities and wget). It also has a suggestion for Windows users ;-).

The question is not if it's available, but whether you can trust such binary. The responsible user's answer is "No". Nook Color's optware installer does exactly that - ships binaries of unknown origin, and dissatisfaction with such approach is what prompted be to develop alternative installer.
The only way you can trust it if [easily buildable] source is provided, then it's up to the user to either compile it themselves or on their own risk to use provided binary. I don't have such source at my hands, and not interested to make it zillion's time just for this adhoc purpose - instead, there should be well-established community project to provide such build framework for all other projects to reuse. I hope, we'll tackle that under auspices of f-droid.org project.

Other possible approach is to just skip "shell script" (and need for busybox) thing at all, and write installer in Java, to be run as normal Android app. That's certainly neat idea which will make users' life easier, and I have that on my (very long) TODO list ;-).

awesome! great work!
i have one small issue though: /etc/hosts doesnt seem to have any effect. a lot of stuff won't work because localhost cant be resolved. any suggestions?

2 onemandivision: Confirmed this issue, looking into it.

Ok, it turns out that GLibc's nsswitch default is weird in favoring DNS over /etc/hosts, and with Google DNS it didn't even look in the latter. Fixed by installing explicit nsswitch.conf:
# ping localhost
PING localhost (127.0.0.1): 56 data bytes
64 bytes from 127.0.0.1: seq=0 ttl=64 time=0.274 ms
Let's dub this 1.0 then (tagged).

Most phones that are rooted have a fairly recent version of busybox on it, which includes wget. Also, standard practice on kernels these days (non stock ones) is to have all scripts that exist in /etc/init.d execute. That would solve any service startup issue.
I don't see any problems with requiring root and busybox
Solves all of the issues.

Hello
I tried the script and i was able to install ipkg on my Samsung Galaxy II
the only problem is... if i try to install any package... i get a segmentation fault error

any advice? :'(

If you already have shell access to your device and don't want to connect via ADB, I modified the script to have the ability to run directly on your device (your device will need at least a functional wget executable already, which I had from SSHDroid):
Code:
# OPTWARE_DIR is where to install optware, it should be on a partition with
# normal Unix filesystem (permissions, etc.)

They can be used as improved shell or in your application, root or otherwise.
A more reliable way to run native functionality than through Busybox.

Rooting the webOS TV

pivotce.com informs that instructions have been published on gaining root access to a webOS TV. This is much harder than on the old phones and tablets. When this was done on legacy webOS, there was a wave of enhancements and tweaks made available to phone users from webOS Internals and other developers.
The instructions can be found on the Russian webOS forums here: webos-forums.ru/topic4650.html (English Translation via Google).
As the thread itself notes, this creates the possibility of fiddling with your TV in a way that may turn it into a large, thin brick and will almost certainly invalidate your warranty. The general user should stay well clear of this.
pivotCE published this for information only and recommend leaving investigations to those who know what they are doing or who can afford to wreck expensive television sets. We will watch to see if anything interesting emerges from this development.

6) Download with WinSCP start-devmode.sh and edit it locally.
You need to add at the beginning
Code:
mount -o bind /media/cryptofs/root/etc /etc
telnetd -l /sbin/sulogin &
Plus you can add the line to launch any App at start, e.g:
Code:
luna-send -n 1 -f luna://com.webos.applicationManager/launch '{"id": "netflix", "params":{}}'
And comment Dev Mode online check.
Here it's mine start-devmode.sh. It's for webOS 1.4. It can be different for other webOS versions:
Code:
#!/bin/sh
mount -o bind /media/cryptofs/root/etc /etc
telnetd -l /sbin/sulogin &
#luna-send -n 1 -f luna://com.webos.applicationManager/launch '{"id": "netflix", "params":{}}'

Ok, so I get run the root app and first ,second , and third stage all are good. then it says try get root password is 1111. But the terminal keeps freezing after that happens. A couple times my tv rebooted too. I cant figure out what i could have messed up. ANyone with any experience using this method have any legit information?

Try to delete all 'cache' files from exploit at /media/developer. It doesn't wotk twice as far as I concerned

Is there anyway I can root my 1.4.0 and if so what r the benefits of the root? Can I install Android or kodi? What's the point

I tried it stil seems to finish step 3 then says enter 1111. But this is where it freezes up and does not get any further.

Is this still working on 3.6? I'm stuck at try to install any app from market.

Which TV and firmware version?
Is this possible with UJ63 serie?

Hi, would the root access allow somehow to connect other bluetooth devices different than LG? Thanks!

You can do pretty much anything to the system with root, even include support for unsupported devices in form of additional kernel modules.
For example, I've added Samba support so I can mount use my NAS (see my blog at ddscentral dot org for details).

Hey guys is it possible to install android apps into WebOS? I just bought an Lg oled LG 55EG9A7V i want to use Perfect Player IPTV but i cant install it right now...Other then that i dont need anything else..
Can anyone help me?

need help about rooting

i can't root Samsung galaxy a02 -- SM-A022F/DS Build No: A022FXXU2BUI3 , android 11 , i dont know what to do for rooting and i dont have firmware file (bootloader unlocked)

To get the superuser access ( AKA root ) to be able to control various aspects of Android OS means you need to perform a certain modification that will root your phone's Android. An unlocked bootloader isn't needed to root Android.
Here is what you have to do to root your device's Android:
Replace Android's Toybox binary - what is a restricted version by default - by unrestricted Toybox v0.8.5.
This e.g. can get achieved by means of a Windows command script making use of ADB coomands.

Typically people do a Google search like "Android Toybox" ...
To save you this search: Toybox is a suite of Linux commands ported to Android.
The commands supported are
Code:
acpi arch ascii base64 basename blkid blockdev bunzip2 bzcat cal cat
catv chattr chgrp chmod chown chroot chrt chvt cksum clear cmp comm
count cp cpio crc32 cut date devmem df dirname dmesg dnsdomainname
dos2unix du echo egrep eject env expand factor fallocate false fgrep
file find flock fmt free freeramdisk fsfreeze fstype fsync ftpget
ftpput getconf grep groups gunzip halt head help hexedit hostname
hwclock i2cdetect i2cdump i2cget i2cset iconv id ifconfig inotifyd
insmod install ionice iorenice iotop kill killall killall5 link ln
logger login logname losetup ls lsattr lsmod lspci lsusb makedevs
mcookie md5sum microcom mix mkdir mkfifo mknod mkpasswd mkswap mktemp
modinfo mount mountpoint mv nbd-client nc netcat netstat nice nl nohup
nproc nsenter od oneit partprobe passwd paste patch pgrep pidof ping
ping6 pivot_root pkill pmap poweroff printenv printf prlimit ps pwd
pwdx readahead readlink realpath reboot renice reset rev rfkill rm
rmdir rmmod sed seq setfattr setsid sha1sum shred sleep sntp sort
split stat strings su swapoff swapon switch_root sync sysctl tac tail
tar taskset tee test time timeout top touch true truncate tty tunctl
ulimit umount uname uniq unix2dos unlink unshare uptime usleep uudecode
uuencode uuidgen vconfig vmstat w watch wc which who whoami xargs
xxd yes zcat
As you might see su is the ROOT functionality.

Actually I'm working on a Windows command script that makes use of ADB what does the job. I'll publish it here when finished:
