Hello y'all,
I can't get the command "wget" to work in the default busybox (using a terminal-emulator) that is installed on Darky's 10.1 custom rom
command: (example)
wget -O /sdcard/download/plaatje.png http://images.androidworld.nl/wp-con...logo-trans.png
error code:
"wget: bad address"
also nslookup google.com gives me: "0.0.0.0" (can't see dns address)
???
(my internet is just working fine though)
Code:
su
mount -o remount,rw /system
echo nameserver 8.8.8.8 > /system/etc/resolv.conf
Okay, finally managed to compile the tun.ko module for 2.6.35.10-g13578ee
To install with adb (thanks to this thread: http://forum.xda-developers.com/showthread.php?t=630703):
Code:
adb shell mount -o remount,rw /dev/block/mtdblock3 /system
adb push drivers/net/tun.ko /system/lib/modules/
adb shell mount -o remount,ro /dev/block/mtdblock3 /system
adb shell
insmod /system/lib/modules/tun.ko
Previously, compiling with NDK-r6b created a tun.ko that didn't insmod. There was a another thread that mentioned that. Reverted back to NDK-r5
Now... to figure out the routing for openvpn.
Trying to compile module?

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
Hi
I'm trying to install this http://forum.xda-developers.com/showthread.php?t=2573441 on my freshly bought and updated GT-P5210 (rooted stock rom).
The script runs to the point where it has to mount the Image. (using the script from the post)
Code:
$bbox mount -t ext2 /dev/block/loop255 $mnt
This fails with 'invalid parameter', and if i remove '-t ext2' it fails with I/O error
Code:
[email protected]:/ $
[email protected]:/ $ cd /storage/extSdCard/Img
[email protected]:/storage/extSdCard/Img $ su

Checking loop device... FOUND
mount: mounting /dev/block/loop255 on /data/local/mnt failed: Invalid argument
Error: Unable to mount the loop device!

Do I tell busybox to overwrite the 'mount' command?
I used TWRP for root/recovery instead of CWM if that makes a difference.

*Edit, turns out it was a bodged image file transfer
Mounting cifs filesystem is a mandatory feature for my needs. I searched some howto about mounting cifs filesystem on a lineage 14.1 OS and didn't find any solution. I've digged the issue and found out a solution without switching selinux to permissive mode. My device is a tablet samsung tab S.
You need to install some additional pieces of software :
. The su command to get root. Following commands require root.
https://download.lineageos.org/extras
. The busybox suite
https://forum.xda-developers.com/android/software-hacking/tool-busybox-flashable-archs-t3348543
You need this software because the mount command of the lineage toolbox (toybox) doesn't support network filesystems.
. The setools-android with sepolicy-inject
https://forum.xda-developers.com/android/software/setools-android-sepolicy-inject-t2977563
Extract the zip file in /data/setools.
When cifs trys to reconnect on a share, it fails with this avc denied :
Code:
<36>[ 1055.524752] [L1: logd.auditd: 2431] type=1400 audit(1511819085.871:227): avc: denied { net_raw } for pid=6208 comm="cifsd" capability=13 scontext=u:r:kernel:s0 tcontext=u:r:kernel:s0 tclass=capability permissive=0
So, you must inject the missing policy which prevent cifsd to well functionning. To inject the allow rule, type :
Code:
/data/setools/sepolicy-inject -s kernel -t kernel -c capability -p net_raw -l
. Finally, mount your remote filesystem with the busybox mount command, and you are done !
Code:
DIR=myshare
[ -d /mnt/cifs/$DIR ] || mkdir -p /mnt/cifs/$DIR
/system/xbin/mount -t cifs -o ro,username=xxxx,password=yyyyy,iocharset=utf8,noperm,file_mode=0777,dir_mode=0777,context=u:object_r:sdcardfs:s0 //10.0.1.1/$DIR /mnt/cifs/$DIR
Thank you hmelg, I am having Lienage os 15.1 installed with su addon on samsung galaxy grand prime.If I install the busybox as per your thread above, does it conflict/impact existing lineage tool box in any way ?
must re build kernel ,add nfs
To further ressurrect a dead thread...
I can get my folders to mount where I want them, but only other root enabled apps can see those files. Regular userspace apps see an empty folder at the mount point. Is there a modern solution to this problem? Everything I've found on the internet so far leads me back to that exact same situation.
