Thank you, for taking the time to put this together for the E4GT community. Nice work
Great. I always wanted to know how to do it.
I decided to write a script to do this automatically.
[size=+1]As before, I provide this with no warranties or guarantees. Use at your own risk. Make a NAND backup of at least System and Data before attempting.[/size]
The script assumes you have busybox and root access.
The script does not check for supported hardware. It has only been tested on the SPH-D710.
The script will check for /mnt/sdcard/external_sd, /mnt/emmc, and /mnt/sd-ext and that at least one is mounted. It bails otherwise. If your external SD card is mounted elsewhere, you can add it to line 9 of the script file (`mountpoint <real path to external SD (no symlinks)>`).
This script must be executed from a live boot (ie, not from recovery) using either Root Explorer, Scripter, a terminal emulator, ADB, or anything else that will run scripts as root.
The file must be on an EXT# partition (just put it in /data and you'll be fine) with 777 permissions unless you're using Scripter.
The script backs up your vold.fstab file to /data/vold.fstab.bak. If the backup file exists, the script will restore it, delete the Link2SD file, and delete the backup file.
Executing the script from Recovery is not advisable.
Executing the script after it has already been executed and the backup file no longer exists is also not advisable.
Your phone will reboot immediately after the script has executed.
Method 1 (terminal emulator or ADB shell):
Put the file from the zip into the /data directory.
Use the following commands from the shell:
Code:
su
chmod 777 /data/eg.link2sd.sh
sh /data/eg.link2sd.sh
Method 2 (Root Explorer | Root Browser):
Put the file from the zip into the /data directory.
Long tap the file, click "Permissions", check every box (the bottom row (there are only two boxes in that row) can be unchecked), and tap Ok.
Tap the file and tap "Execute".
Method 3 (Scripter):
Put the file from the zip wherever, but remember where.
Open Scripter, tap the "+", tap "Import", find the file, and tap it.
Tap the file in the list, tap "Run script", make sure "Execute script as root" is checked, and tap "Execute".

Someone smarter than me can validate or disprove my answer here, but I believe JB has different file system mount points than ICS. (he said he did this on BK)

You are correct. JB has a different pre load set up. I think you are rite...this was created on the ICS Kuban.

That's just it, it works fine, but System, Settings, and some other system apps crash consistently while the internal sdcard is mounted to Link2SD's directory and the external sdcard mounted in its place. I even made sure to edit my scripts to change where the external and internal would be remounted to (it's /storage/sdcard0 and /storage/extSdCard respectively).
P.S.: It's 4.2 that changes how mounts are seen by or accessible to apps.
Edit: To clarify, the directories get successfully changed around as intended.
Edit 2: Oh, and the phone reboots itself after a few minutes. I had to fix it via Recovery with ADB because the phone wouldn't stay up long enough to do it the normal* way. * Transferring files to the SD card via USB and moving them to their proper destinations via Root Explorer.
I figured out why I was having a problem. I was mounting /dev/block/mmcblk0p12 to /storage/extSdCard. The problem is that Android 4.1.2 stock uses /dev/block/mmcblk0p12 as "overflow" for system apps.
I am currently unwilling to test this on my phone at this time. My setup would require /dev/block/mmcblk0p11 to be an EXT4 file system which, judging by what I see in init.rc, is going to get reformatted as exFAT on boot. Besides, Link2SD has since been fixed to find the second partition on the external SD card for the SGS2.
I have successfully mounted my internal SD card to /data/sdext2, mounted my external SD card to /storage/sdcard0, and bound /storage/sdcard0 to /storage/extSdCard (for backward compatibility) using the following scripts.
[size=+1]I provide this information with no warranties or guarantees and I only tested it on the Sprint Epic 4G Touch with stock rooted Jelly Bean 4.1.2. Use it at your own risk.[/size]
Requires:
root
busybox
basic knowledge of shell scripts and Linux (not necessarily required, but it doesn't hurt)
Notes:
Make sure /system/etc/init.d/12binds, /system/bin/debuggerd, and /system/bin/debuggerd.bin are executable. Just to be safe, you can execute this from a terminal emulator (the asterisk will make it get multiple files at the same time).
Code:
mount -o remount,rw /system
chmod 755 /system/bin/debuggerd*
chmod 755 /system/etc/init.d/12binds
mount -o remount,ro /system
The reason I converted my SD card to EXT4 is so I can move&bind internal app data (the stuff in /data/data/app.package.name) to /data/sdext2/data/app.package.name and preserve file permissions. exFAT does not support this.
Terminal emulator - Executing this command will wipe the SD card and convert it to EXT4. This is optional:
Code:
mkfs.ext2 /dev/block/mmcblk0p11

To make the above work:
If this is too much for you, don't do it.
Copy /data/data/app.package.name to /data/sdext2/data or if the folder already exists in /data/sdext2/data, copy the contents of /data/data/app.package.name to /data/sdext2/data/app.package.name. Use Root Explorer or any other root file explorer that will preserve the owner of the files and their permissions. Do not use the "move" option or you will be making new folders and trying to figure out what the owner and group should be!
Open each folder except lib in /data/data/app.package.name and delete everything in them.
Execute /system/etc/init.d/12binds or reboot.
I bought an SGS4 and promptly broke the SD card I got for it, so I took the one from my S2 and put it in the S4. I then changed the vold.fstab file back to stock. Unfortunately since the internal SD card is EXT formatted, it won't mount as an SD card. This means that any app that relies on the SD card may not work. Apps that use the path work if I mount the SD card via shell script, but there's a caveat: the files that get put there (e.g. $sdcard/Android/data/<app name>/cache/<stuff>) have their owner/group set to that of the app and no other app can use it without changing the files' owner, group, and permissions first. Camera and Gallery apps won't work at all regardless of whether or not I mount the SD card, at least not the ones I've tried (stock camera and gallery, Camera ICS, Gallery ICS, and Social Gallery). Otherwise the phone works fine without error.
Edit: If I mount a temporary file system (mount -t tmpfs /dev/null /storage/sdcard0), I can get the Camera to work, but the Gallery still complains and any pictures get deleted after reboot. This gave me an idea, though: mount the tmpfs and then bind /data/sdext2 to /storage/sdcard0. This worked, for the most part. Gallery apps still don't like it, but the Camera works. I still have to change the owner, group, and permissions to be able to do anything with pics.
For the record, this seems to work the best:
Code:
chown media_rw:media_rw /data/sdext2
chown media_rw:media_rw /data/sdext2/DCIM
chown media_rw:media_rw /data/sdext2/DCIM/*
chown media_rw:media_rw /data/sdext2/DCIM/Camera/*
chmod -r 775 /data/sdext2
/system/bin/debuggerd
Code:
#!/system/bin/sh
LOG=/data/debuggerd.log
echo "$(date) mounting..." > $LOG

echo debuggerd.bin launched >> $LOG
exec /system/bin/debuggerd.bin
I could change it back to exFAT, but I don't wanna.

That script was written for the Galaxy S2 with ICS. You'll have to modify it to work in whatever device and OS you have and I don't have either of them, so you're on your own.

Mods like this eventually burn out extsdcards, when that happens the device won't boot, they also don't work without the modified sdcard inserted. If it ever burns out it is nearly impossible to get the device working again. Just a heads up.

Google seems to have closed outbound connections to the NTP port (123). Lucky, one can easily reopen it with the following script. Execute it as root post-boot with ROM Toolbox or similar.
Code:
#!/system/bin/sh
iptables -A OUTPUT -p udp --dport 123 -j ACCEPT
Edit: So it turns out that init.d is too soon. It must be executed post-boot using a script executer like ROM Toolbox, Tasker, Script Manager, etc.

Have busybox? Wish you could type "grep foo" instead of "busybox grep foo" ? This simple shell script checks your busybox for supported commands and softlinks them from /system/bin to wherever the first busybox it finds in the $PATH is.
Since I screwed up my links a couple times making this, there's also a script that strips every link to busybox out of /system/bin.
These scripts do basically no error checking. They require root access, but they don't check for it. If you don't know how to read a script to see what it does before you run it, don't run it.
That said, it's handy.
Code:
#!/system/bin/sh
# linky.sh: softlink busybox to all the commands it supports
# Now with zero error checking! Beware :P
# -speef
busybox &>/dev/null || exit 1
bbl=`busybox which busybox`
ready=0
busybox mount -o rw,remount /system
>./linky.log
for cmd in `busybox`
do
cmd=`echo $cmd|busybox awk -F, '{print $1}'`
if [ $ready -eq 0 ]
then
if [ $cmd == "functions:" ]
then
ready=1
continue
else
continue
fi
fi
echo ln -s $bbl /system/bin/$cmd
busybox ln -s $bbl /system/bin/$cmd &>> linky.log
done
busybox mount -o ro,remount /system
echo "see ./linky.log for errors!"
And its counterpart, which removes all links to busybox from /system/bin:
Code:
#!/system/bin/sh
# delinky.sh: remove all busybox links from /system/bin
# Now with zero error checking! Beware :P
# -speef
busybox &>/dev/null || exit 1
busybox mount -o rw,remount /system
for cmd in `busybox find /system/bin -type l -exec ls -l \{\} \; | busybox grep busybox|busybox awk '{print $6}'`
do
echo rm /system/bin/$cmd
busybox rm /system/bin/$cmd
done
busybox mount -o ro,remount /system
ERROR: chroot: can't execute "/bin/bash" no such file or directory on Android
Hi guys,
I have a problem with "change root" command when I setup ubuntu to run on android. My tablet is Samsung galaxy tab 3 10.1, android 4.4.2 . I followed this tutorial step by step: galaxytabhacks.com/galaxy-tab-10-1-hacks/how-to-install-ubuntu-linux-on-galaxy-tab-10-1-tabuntu(excuse me, I can't post link, please copy and paste help me) but when I run "bootubuntu" script it threw error as title above.
This is bootubuntu script
Code:
#modprobe ext2
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
export kit=/sdcard/ubuntu
export bin=/system/bin
if [ ! -d /data/local/ubuntu ]
then
mkdir /data/local/ubuntu
fi
export mnt=/data/local/ubuntu
export PATH=$bin:/usr/bin:/usr/sbin:/bin:$PATH
export TERM=linux
export HOME=/root
export bbox=/system/xbin/busybox
$bbox mknod /dev/block/loop255 b 7 255
$bbox losetup /dev/block/loop255 /sdcard/ubuntu/ubuntu.img
$bbox mount -t ext2 /dev/block/loop255 /data/local/ubuntu
$bbox mount -t devpts devpts $mnt/dev/pts
$bbox mount -t proc proc $mnt/proc
$bbox mount -t sysfs sysfs $mnt/sys
sysctl -w net.ipv4.ip_forward=1
echo "Setting /etc/resolv.conf to Google Open DNS 8.8.8.8 and 8.8.4.4"
echo "nameserver 8.8.8.8" > $mnt/etc/resolv.conf
echo "nameserver 8.8.4.4" >> $mnt/etc/resolv.conf
echo "Setting localhost on /etc/hosts "
echo "127.0.0.1 localhost" > $mnt/etc/hosts
echo "READY TO ROCK AND ROLL BABY! "
echo "Brought to you by NexusOneHacks.net and the open source community! "
echo " "
chroot $mnt /bin/bash #error here
#After exit command is executed clear it all up
echo " "
echo "Shutting down Ubuntu"
$bbox umount $mnt/dev/pts
$bbox umount $mnt/proc
$bbox umount $mnt/sys
$bbox umount $mnt
$bbox losetup -d /dev/block/loop255 &> /dev/null
And this is result
Code:
