OK i have a question about 00tweaks and other startup scripts within the init.d folder.
As i understand it the init.d folder and everthing inside is executed on startup. obviously each script is executed in alphabetical order.
this would make the 00tweaks executed first.
My question is, looking inside the 00tweaks it looks as if it remounts a majority of the filesystem in a special way. (noatime,nodiratime ) for reducing cpu cycles to get more battery life.
Now my question si, does the special mounting get undone when my 05cpuclock script is ran.... which does the following
Code:
mount -o remount,rw -t yaffs2 /dev/block/mtdblock1 /system
echo $CPU_MIN > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq
echo $CPU_MAX > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
echo $CPU_GOV > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
mount -o remount,ro -t yaffs2 /dev/block/mtdblock1 /system
would it be beneficial to make the 05cpuclock script execute before the tweaks (by renaming either)?

The remounts there are totally useless, delete them; sysfs is automatically mounted rw on /sys; not on /system.

hmm... ill have to look into it.
simply changing the order around of the scripts so that the cpu clock script is executed before the tweaks.... filenames of 00cpuclock and 00tweaks, seems to have changed stuff quite a bit. 9hrs 25min on W/ 79% bat life left.... extrapolate that out and we get 40ish hrs of bat life... before hand i was down round 25-30 hrs.
tho obviously bat life is very dependent on usage of the phone, and its hard to use it in a simmilar manner each day.

I'm not 100% sure this is the right area for this, so feel free to move it and let me know.
I'm trying to make a scripts that mount the system as rw and ro respectively with an echo to the terminal. However, I'm having a problem, when I add the echo part in, the console returns a directory not found error for the mount operation.
For example, my rw file looks like:
Code:
mount -o remount,rw -t ext3 /dev/block/mmcblk0p25 /system
echo "System mounted as read/write!"
Why should I get an error from this? Is notepad not appropriate for writing the scripts?
As far as I remember, notepad doesn't use the linux style of newline commands. I'd suggest using notepad++ (and set line endings to unix) or try that exactly on the device in gscript. I believe it's reading it all as one line (windows line ending != unix line ending). Hope that helps.

It should be this:
Code:
set /p sdkdir=What is your SDK directory?
cd %sdkdir%
adb wait-for-devices
adb shell su
adb shell mount -o remount,rw -t ext3 /dev/block/mmcblk0p25 /system
echo System mounted as read/write
pause
exit

Appreciate the response, but I'm using these scripts from the phone, not in adb. Still, good post.
Suppose I did forget to add the 'su' before trying to remount.
All right... I guess it's time to "ask the experts". My linux background has not been very much help here... ARGH!
Okay, I have two script that I have written that are supposed to mount /system as RO and RW respectively. Very simple:
To mount rw:
Code:
#!/system/bin/sh
mount -o rw,remount -t ext3 /dev/block/mmcblk1p21 /system
To mount ro:
Code:
#!/system/bin/sh
mount -o ro,remount -t ext3 /dev/block/mmcblk1p21 /system
I manually ran the mount -o rw,remount -t ext3 /dev/block/mmcblk1p21 /system command and adb pushed them to /system/xbin as mountro and mountrw and chmod both to 755.
In ADB I try to execute:
Code:
/system/xbin/mountrw
and get an error stating:
Code:
/system/xbin/mountrw: not found
I even try:
Code:
/system/bin/sh /system/xbin/mountrw
and I get this error:
Code:
mount: No such file or directory
Okay, so I figured out that it is having a problem trying to find the mount command, so I modify the script to:
Code:
#!/system/bin/sh
/system/bin/mount -o rw,remount -t ext3 /dev/block/mmcblk1p21 /system
I then re-run this:
Code:
/system/bin/sh /system/xbin/mountrw
and I'm still getting this friggin' error message!
Code:
mount: No such file or directory
When I run it through Script Manager I get the same error:
Code:
mount: No such file or directory
This should just friggin' work damn it! (Sorry, very frustrated.)
Also, it would be nice NOT to have to type the path to the script. I can run ZepplinRox V6_SuperCharger script from the ADB command line just by typing from the directory I have it in:
Code:
sh V6_SuperCharger_for_Android-update9_RC3.2.sh
No absolute path, no ./ path... WTF? ARGH!
Okay, I KNOW this is friggin' possible just by the fact that I can run Zep's script in ADB...
So, any takers? Thanks in advanced...
Friggin' Ciao.
[EDIT]
Okay, I figured out a work around for this... I probably should not work on this after working at work all day... But, that is another story...
I have heavily modified the script files I have created. They are still called mountrw and mountro and the contents are as follows:
mountrw:
Code:
#!/system/bin/sh
# This mounts the /system file system as Read Write in order to modify or add
# files to the /system file system.
busybox mount -o remount,rw / 2>/dev/null
busybox mount -o remount,rw rootfs 2>/dev/null
busybox mount -o remount,rw /system 2>/dev/null
mountro:
Code:
#!/system/bin/sh
# This mounts the /system file system as Read Only which is the default when
# Android is booted.
busybox mount -o remount,ro / 2>/dev/null
busybox mount -o remount,ro rootfs 2>/dev/null
busybox mount -o remount,ro /system 2>/dev/null
So, after poking around in ZepplinRox's V6_SuperCharger script, I found those values repeated several times, so that helped point me in the right direction. The next problem I had was getting the scripts to "run from anywhere". I still haven't figured that one out yet, and the VERY MESSY solution to that is to put the two scripts in /. I know, I know, I know... that is the most dangerous place to put it.
So, when I first log into the ADB shell all I have to type is
Code:
sh mountrw
and when I'm done, type
Code:
sh mountro
So, As the work around, this works. I really don't recommend anyone else doing this because of the data security risks that you open your phone up to... Yes, I'm aware of them and that is why I am asking now for some help in having the ability to run a script globally, from anywhere in the android file structure. I don't mind typing the "sh" in front of the script since I sometimes must do that in linux. I have noticed that the $PATH of Android doesn't allow scripts to be executed unless you type the absolute path to the script, or are in the same directory as the script.
Okay, so again to ask: Is there any way to execute a script without having to type the absolute path to it? Thanks!
Ciao! (MUCH calmer now then when I first wrote this post...)
[/EDIT]
I don't use adb much at all.
Usually I move stuff around with root explorer and use terminal emulator a lot.
I assume you ran everything as superuser as I sometimes forget to type su first
Maybe the sh command work on the supercharger script because it has the .sh extention.
You can try typing "bash mountrw" since that works when I install the script to /system/xbin/V6
But after reading your post I looked and saw I forgot about permissions so I did chmod 755 and now this works...
su
V6
heh..
I don't have tp type "bash V6" anymore

Yes, I ran everything as su. (I'm a linux admin guy, so su and sudo is next to natural for me...)
Okay, so you put the mountrw script in /system/xbin/V6/ ??
Also, it is an sh script. I identify that in the first line of
Code:
#!/system/bin/sh
I have changed it to bash and same problem. Oh well. I think I can live with the scripts at /
Thanks though!
Ciao!
Hello everyone, I'm trying to figure out how to write a script to copy three .mp3 files from three different locations all to /system/media/audio/ringtones. So far, I'm in a bit over my head and I was wondering if anyone here could help me please?
Thanks in advance!

Well bud, honestly, it's not even worth all the writing it would take to compile a script for such an easy task via and file explorer that supports root functions. Simply copy n paste all into one folder, mount your /system -r/w and then the good ol multi-select button, copy to clipboard, browse up to /system/media/ringtones or /system/audio (whichever your phone model stores your system sounds/ui crap in), then after pasted to destination folder simply remount -r/o, reboot phone, voila!

Haha, thanks -- that's what I usually do but if it's too complicated it's not worth it.
Open a new text file, and write this:
Code:
#!/system/bin/sh
mount -o rw,remount /system
cp location1/file.mp3 /system/media/audio/ringtones/file.mp3
cp location2/file2.mp3 /system/media/audio/ringtones/file2.mp3
cp location3/file3.mp3 /system/media/audio/ringtones/file3.mp3
mount -o ro,remount /system
Save it (the extension doesn't matter) and that's it. You can run it using script manager, or the terminal emulator (in this case you need to get root permissions first, using the su command).
Also you can add some messages (to get a nicer script, you know ), this way:
Code:
#!/system/bin/sh
echo "Mounting /system as RW..."
mount -o rw,remount /system
echo "Copying files..."
cp location1/file.mp3 /system/media/audio/ringtones/file.mp3
cp location2/file2.mp3 /system/media/audio/ringtones/file2.mp3
cp location3/file3.mp3 /system/media/audio/ringtones/file3.mp3
echo "Done. Mounting /system as RO again..."
mount -o ro,remount /system
echo "All done. Have a nice day =)"
Please be careful while using scripts, otherwise you'll brick some devices :silly:

This is exactly what I wanted and it works beautifully! Thank you so much!
If I put script like thisone (classic copy-paste) in /system/etc/init.d, is it possible to configure that runing on ewery boot? And how?
Thanks.
Haven't tried this yet for fear of bricking, can someone help to see it this will work? I'm just trying to have a script to be placed on the homescreen so I can easily disable/enable the mediascanner/screenshot function. By the way, cp copies files, and cp -r actually moves (cut-paste) files, right?
#!/system/bin/sh
echo "Mounting /system as RW..."
mount -o rw,remount /system
echo "Movingfiles..."
cp -r /system/prv-app/MediaProvider.apk /system/prv-app/newfolder/MediaProvider.apk
echo "Done. Mounting /system as RO again..."
mount -o ro,remount /system
#!/system/bin/sh
echo "Mounting /system as RW..."
mount -o rw,remount /system
echo "Moving files..."
cp -r /system/prv-app/newfolder/MediaProvider.apk /system/prv-app/MediaProvider.apk
echo "Done. Mounting /system as RO again..."
mount -o ro,remount /system
Is it possible to do the same but with a folder+ content and not just a file?
Best thought to testing scripts, would be to add an android emulator to your computer. The one I use is nox. Its great for testing scripts and a variety of other things as well. Nox is an android based application, made jjust like a phone. All the features and extensions that your normal everyday android has, this emulator has as well.
Hi guys,
I am using a Huawei T1-701u. I can consistently get root using iovyroot. I have added all the firmwares I can find and created a pull request.
There seems to be some sort of protection on the system partition however. This manifests in two ways. Firstly changes to the partition are magically reverted on reboot. Secondly, I sometimes get an error when mounting /system as rw saying it is readonly.
I have some scripts up on GitHub: /chrisfraser/HuaweiRoot (Sorry you have to search. This is my first post). This eventually works, but it is indeterminate. Sometimes it works first time. Other times it can take 20 tries. Below is the important remount code.
Code:
install_perm() {
cat $1 > $2
chown 0.0 $2
chmod 755 $2
}
echo '[*] Starting root install'
mount -o rw,remount /system
setenforce 0
install_perm $BIN/su /system/xbin/su
install_perm $BIN/su /system/xbin/daemonsu
install_perm $BIN/install-recovery.sh /system/etc/install-recovery.sh
ln -s /system/etc/install-recovery.sh /system/bin/install-recovery.sh
mount -o ro,remount /system
sync
echo '[*] Root install complete, rebooting'
sleep 5
reboot
Thanks in advance
Hi all,
I've been looking around to solve my /cache problem of it being only 17MB.
Found a temporary fix but that needed to be implemented or executed every boot up.
And since I am to lazy or stupid to remember that every boot I search for another solution ...
Combined a script from someone else with some stuf I found somewhere else...
Descriptions are in the code....

echo "If your new /cache partition is mounted with the given size than all is good"
echo "These are the configurations now"
# exec df command to show config now
df
sleep 10
exit
With this your /cache will be changed to whatever values you give in the code...
For safety remove the cachefix.sh afterwards...
Added cachefix.txt, download and rename to cachefix.sh
