i am trying to change the init script for APP2SD by [email protected] (cyanogen). it is the standard script for all custom roms.
i want move dalvik cache back to phone memory and app, app-private and data to system/sd. data/data/ is normally moved back to phone memory by the script if someone moves it to system/sd/ due to "compatibility" reasons.
i have edited the script and removed this part.
the problem is that after installing some apps, etc. phone memory is at 13mb and one cant install any additional apps.
also, how do i replace the previous 40a2sd script? i ran into a wall when trying...

16) My GoogleMaps (or other application that uses OpenGL) is freezing/irresponsive. What can I do?
Open terminal or adb shell and type these commands:
Code:
$ su
# mount -o rw,remount -t ext3 /dev/block/mmcblk1p21 /system
# echo sysctl -w vm.min_free_kbytes=4096 >> /system/etc/install-recovery.sh
# chmod 744 /system/etc/install.sh
# mount -o ro,remount -t ext3 /dev/block/mmcblk1p21 /system
Hi all i have some question about this!
So this is a countermeasure like a mod? I type it in then everything goes well?
Or i have to type it after every restart?
and if i write this it kills the app or it will run before the freezing?
is this working with opengl games?.
Thanks!
Ernő
when i tried typing this line
# chmod 744 /system/etc/install.sh
no such file exists
maybe this?
# chmod 744 /system/etc/install-recovery.sh
PS: Has this anything to do with recovery 2ndinit or something?
not exactly sure what this does, I think it makes sure at least 4096kb of RAM is free.
but try
$ su
# mount -o rw,remount -t ext3 /dev/block/mmcblk1p21 /system
# echo vm.min_free_kbytes = 4096 >> /system/etc/sysctl.conf
# mount -o ro,remount -t ext3 /dev/block/mmcblk1p21 /system
# sysctl -p
it worked for me and has kept the setting after restarts
Just download sysctl in market and set it at 4096 it higher. If you have setvsel, it had option to increase min kb to 4096

My Defy 2.2 also freezes when trying Maps (the only one that works is 5.0.0) - so I've tried sysctl with 8192 at min. kb. free.
No success, still freezing with 5.6.0/5.7.0 .
Uninstall updates in maps then update a fresh one.

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

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
