This is hack for the userinit.sh script that allows to override
system programs with different binaries or just add some new
executable programs to your rom as you can use your ext3 partition
as storage. One more advantage is that your customizations
will be persistent even after a update.
For this to work you have to add this lines to your /system/sd/userinit.sh script:
Code:
mount -o remount,rw /dev/rootfs /
mkdir /usr
chown root.root /usr
chmod 755 /usr
mkdir /system/sd/bin
chown root.shell /system/sd/bin
chmod 755 /system/sd/bin
ln -s /system/sd/bin /usr/bin
mount -o remount,ro /dev/rootfs /
After a reboot, you'll find a newly created bin
directory in /system/sd/ linked to /usr/bin.
/usr/bin is the first directory to be searched
in path in CM-mod ROMs so any program dropped
there will be found and executed before others with
same name in the system. So you can simply:
Code:
adb push new_program /usr/bin
adb shell
cd /usr/bin
chmod 755 new_program
chown root.shell new_program
This is experimental stuff and therefore USE IT AT YOUR OWN RISK.
Tested on CM-mod-3.6.7.2 and CM-mod-3.6.8 and works fine for me.
So if I were to use this method. I could 'truely' replace the home screen with one of the 3rd party ones. ie aHome or dxTop? As it is now, I've noticed that even setting aHome as default, Home still runs in the background. Using Advanced Task Manager to confirm this btw.
If this is the case, I'll be using this shortly. As I'm tired of just running 3rd party programs in addition to the programs they are suppose to replace.
Its like using windowblinds in windows, instead of just replacing the whole shell. lol

This only lets your run cli programs. This is below the dalvik system so it won't help you change the launcher.apk for ahome or dxtop.
Ok I see what your saying now. Misunderstood the exact intent of the changes
Cool trick, thanks. I already had a /system/sd/bin, so I modified it a little to skip creating it and doing the chmod etc on it.
Slight mod to avoid the whole thing if /usr is already there.. .
Code:
if ! [ -d /usr ]
then
mount -o remount,rw /dev/rootfs /;
mkdir /usr;
chown root.root /usr;
chmod 755 /usr;
ln -s /system/sd/bin /usr/bin;
mount -o remount,ro /dev/rootfs /;
fi
This is useful to me as my userinit.sh is the new one from the compcache thread and can be run to get status info on compcache after boot. No need to remount the filesystem and all that when what we need is already there.
I don't think you can skip the creation of /usr as it is lost
after a reboot at least on cm-mod, you can skip the creation
of system/sd/bin if it already exists tough. OTOH running:
Code:
mkdir /usr
chown root.root /usr
chmod 755 /usr
mkdir /system/sd/bin
chown root.shell /system/sd/bin
chmod 755 /system/sd/bin
ln -s /system/sd/bin /usr/bin
will do no harm as mkdir and ln will fail if the targets already exist
and chown and chmod will just ensure that you can run your
programs.To be on the safe side i would suggest:
Code:
mount -o remount,rw /dev/rootfs /
mkdir /usr
chown root.root /usr
chmod 755 /usr
# we should check if /system/sd is mounted
if [ ! -d /system/sd/bin ] ; then
mkdir /system/sd/bin
chown root.root /system/sd/bin
chmod 755 /system/sd/bin
fi
ln -s /system/sd/bin /usr/bin
mount -o remount,ro /dev/rootfs /
This would be a great place to put a set of the GNU utilities like ls, ln, cp, mv, etc to go along with bash. Busybox is great and all, but there are some advanced options in the GNU versions that aren't available in Busybox. Has anyone compiled them for Android? I might try copying the Debian ones over and see if they work without the rest of the chroot. I'm thinking I'll need at least some of /lib from debian for them to work though.

Have you tried a fully configured busybox with desktop options enabled?
Attached just for reference my .config.

Nope. Is there a binary available? I don't have a cross compiler set up right now.
Try this, You can create all the symlinks with this command:
Code:
adb push busybox /usr/bin
adb shell
cd /usr/bin
./busybox --install .
For full functionality you should also add /etc/passwd, /etc/shadow, /etc/group, /etc/gshadow. I link them to /system/sd/etc/ to have them rw
Code:
mkdir /system/sd/etc
chmod 644 /system/sd/etc
/system/bin/chown root.root /system/sd/etc
/system/bin/chown root.root /system/sd/etc/passwd
/system/bin/chown root.root /system/sd/etc/group
/system/bin/chown root.root /system/sd/etc/shadow
/system/bin/chown root.root /system/sd/etc/gshadow
/system/bin/chown root.root /system/sd/etc/fstab
chmod 644 /system/sd/etc/passwd
chmod 644 /system/sd/etc/group
chmod 600 /system/sd/etc/shadow
chmod 600 /system/sd/etc/gshadow
ln -s /system/sd/etc/passwd /etc/passwd
ln -s /system/sd/etc/shadow /etc/shadow
ln -s /system/sd/etc/group /etc/group
ln -s /system/sd/etc/gshadow /etc/gshadow
Remove the su link to busybox for now as it interferes with
the superuser app (otoh you could set a root passwd and
use busybox's su BUT ONLY FROM A SHELL)
Code:
rm /usr/bin/su
You should also:
Code:
passwd root
addgroup -g 65534 nogroup
You can even use ash as your default shell by doing:
Code:
if [ -e /usr/bin/busybox ] ; then
mount --bind /usr/bin/sh /system/bin/sh
fi
# Fix scripts in /system/bin
for i in am ime input monkey pm svc
do
if [ `grep -c "#!/system/bin/sh" /system/bin/$i` -eq 0 ] ; then
echo "#!/system/bin/sh" > /system/bin/$i.tmp
cat /system/bin/$i >> /system/bin/$i.tmp
mv /system/bin/$i.tmp /system/bin/$i
chown root.shell /system/bin/$i
chmod 755 /system/bin/$i
fi
done
Thanks! That worked great.

Hey farmatito - just stumbled onto this thread and am going to follow this but I am unclear on how to remove the su link to busybox? Any direction would be appreciated! Thanks.
Edit: I realize you mean to just rm it from /system/sd/bin - duh. thanks for this thread! I like having the full busybox bin.
cd /usr/bin

Yeah, I figured that out - thanks. I had edited my above post saying such.
another question for you - I was going through your busybox config file - and am wondering which directory you store it in so that it is used when installing busybox?

Quick stupid question please... tried searching but haven't found much.
After doing the userinit.sh mod shown here and using the new busybox (thanks for that, btw!), I noticed that a lot of the commands (including 'ls' which is now using /usr/bin/ls) show ansi colors in a terminal that supports them (i.e. 'Terminal' or 'Better Terminal' app) which is awesome but 'adb shell' looks mostly horrible with escape sequences instead of colors, like this:
Code:
# cd /system/sd
cd /system/sd

Do you guys set your $TERM variable to something that makes the adb terminal more "sane" or is not possible because adb is limited and I should just ssh or telnet in, etc.?
I've tried setting $TERM to various standard things (ansi/vt100/xterm/etc.) but the dumb adb terminal remains.. well.. dumb.

What terminal are you using?
I use konsole on linux and everything looks fine.
Cannot say if there is a suitable terminal for windows,
maybe the one that comes with the mingw compiler.
If nothing works you can just:
Code:
cd /usr/bin
rm ls

Many thanks!
Oh, sorry, I should have specified that.
This was using adb from my Vista x64 laptop (yeah, sorry, stuck with win32 for using adb so terminal choices rather limited).
So, basically, it was just running "adb[.exe] shell" from a Windows command prompt.
Tried bash under cygwin and even though it has full ansi coloring support, it looks like adb.exe isn't very terminal friendly because extended/escaped ansi still don't translate.
No big deal; I'll remove /usr/bin/ls for now or temporarily alias 'ls' to /system/xbin/bb/ls while I'm in an adb shell.
Wondering what else I could be using via the USB connection to get a shell prompt within my G1... easiest way is to turn on the wifi and telnet/ssh in, I guess?
EDIT: Duh, just started telnetd and forwarded the port using adb and problem solved (using putty to telnet in as described here and it works very nicely).

If you are on a windows pc, try using cygwin - works great.
Hey guys, just got my hands on one of these suckers, it runs 2.1
Can anyone point me in the right direction to get root?
Im also looking for froyo, however dont expect it soon, manufacturer is working on it.
Sent from my S7 using XDA App
I second davidcampbell! We need froyo here
The root method is the same as the s7.
download z4root from market and root, after wards install busybox by titanium backup and you are set.
The app2sd mod works for this device since it is similar to the sony x10 on 2.1 but is risky because i lost wifi aftewards. So just explore until we get some real developers working on it hopefully cm6.1 port but after huawei realeases the recovery.img and source to mess around with though.
being able to overclock to 1ghz wouldnt hurt either.
S7 Bootloader?
Has anyone figured out how to get into the bootloader for this device?
Havent been able to through any apps \ commands. Just go to a black screen and thats it, and recovery sends you into factory settings for your device
I only know that pressing back key and call\send key when when powering on the device puts it into update mode.

Zomg, nice, thank you alexisprz, it's rooting time
I really wish Android had a better term for rooting, it sounds like I'm either breaking it, or trying to cram my man bits into it some how.
Will this affect my ability to use the manufacturers update to froyo in the future?
UPDATE: z4root worked great, I installed busybox no problemo, very happy forum member here
sir i just bought one telstra touch tab can you plz help me to debrand it and unlock it i also have jtag too

if you have to move directory i think that you have to do: mv -v -t source dest
cause -t is used for specified that you want move a dir and -v to show what the command are doing....
for the ln command use this format: ln -s /my/existing/directory thisismylink
...and i see that you wrote "1n" and not "ln" but maybe is a paste error

Hey, I installed BT5 arm on the Motorola Xoom wifi and i would like to know how to completely remove it from my device. My device is rooted and i have tried to delete the whole BT5 file with astro file manager and absolute file manager but neither of them worked. I was wondering if anyone knows another way of doing it.
I tried deleting it with commands in terminal emulator but its a read only file. Wouldn't chmod help with that? If so how would i use it?

Go read the backtrack 5 thread. There is a link on how to remove it. That really should be the first thing you check before asking
ok thanks, ill do that the next time i have a problem
I couldn't find it. I think it might be a tiamat BT5 img and i have the remover tool but im not quite sure how to use it. I just flashed it like i would do with a rom but it says installation failed. what would i do to fix that?

Common knowledge - system must be set to RW
Here is an alternate route- manually
How To:
ADB Shell Folder Removal - (we will use BT5 as an example)
++++++++++++++++++++++++++++
1. Connect Xoom to pc
2. Boot into recovery
3. Toggle to internal storage as /sdcard
4. mount /data
Enter adb shell via pc
(cd to file location) in this case BT5, is in the sdcard directory
Code:
Code:
cd /sdcard #
(once typed, you will be at.... /data/media prompt)
if after the above command and you are not at the /data/media prompt start over)
Code:
Code:
rm -r BT5
(BT5 is the stubborn Folder)
*Side note ... This works for any other stubborn folder that you want to delete as well...
USE AT YOU OWN RISK - MAKE SURE YOU DO A BACKUP FIRST
If this was helpful Hit The Thanks!
it didnt work it said that rm failed for BT5, permission denied

do chmod 777 BT5 to give all permissions and then when i tried to remove it again it was still denied.
I looked up the permissions of the file and its set to rwxrwxr-x. so chmod apparently didn't work
