So I have been using Terminal emulator to load new boot loaders on my phone and I use this code:
Code:
su
mount -o remount,rw /system
cp /file location/bootanimation.zip /system/media
My question for you guys is, what does the second line mean? I mean sure I can memorize the code and use it but I'm trying to figure out how to read it and it doesn't really make sense to me.
Code:
mount -o remount,rw /system
We use the mount command, with the option remount (meaning unmount and then mount again), and the desired access rights ( rw = read and write) on the folder /system.
This mean we have a folder /system which is probably mounted as READ ONLY.
To change access rights you have to unmount first and then mount with the new access rights.
We want to change the access rights of system and we don't want to change its mount point. So we use mount command with the option remount and our desired rights.
Does this clarify it for you?

Thank you so much!
hmm, i logged in as su but did not perform the remout code, ive found a tool to calibrate my xperia x10 mini pro accelerometer but when i executed it and did the required operation, it said the configuration was complete and yet the accelerometer was left unchanged, could this mean that because i did not use the mount remount command before using the tool that is why the program did no changes at all?

I want for my /system to be mounted as read/write automaticly upon startup of the phone using this command "mount -o,remount rw /dev/block/mtdblock3 /system"
How can i make this command to be executed as ROOT when my phone starts up.

Why do you need this?? Just download droidsans andwhen you need read write just use that.
I need it bc im trying to move my apps to my sd card.....if i have the /system in read only mode then the phone crashed when i try to install a new app but it works fine when my /system is read and write
I doubt you need to mount /system rw. Do ls -l in /system and make sure sd has the same owner/permissions as the other dirs and it should work.

i have followed the instructions in the post titled apps on sdcard and it works fine without mounting the system RW. look at that post and follow those directions.
See: http://forum.xda-developers.com/showpost.php?p=3386761&postcount=2
Just add the line to The File insted of the Path Part.
The is called after system is mounted so it should work fine
Suddenly I couldn't find any of my ringtones that stored on the /sdcard/ringtones directory from Ringtones Settings.
The /sdcard/ringtones is still avaliable on the sdcard and If I tried to play them throw the mp3 player they works fine.
I found out that the sdcard is mounted as Read-Only and not Read/Write as before. Even if I plug it in to the PC I can't change any of the data on the sdcard only read it.
The latest change that I made few days ago was to store all cache files on the sdcard. I am not sure that this is the reason but it could be.
Does anyone here have any idea why it happened?
install Rings Extended from the market. Open your soundsettings with the program. It will prompt to open with rings extended or standard.
Don't know about the read-only stuff, but you could take a look at the ownership and the rights you have as a user/admin... if all fails.. format?
thanks for the advice, I will try it...
does anyone have more ideas regarding the read only issue?
yes could this be your problem too http://forum.xda-developers.com/showthread.php?t=473256
unfortunately its not the same issue, I have root access to the phone and when I run the mount command this is the output I have for /sdcard
/dev/block/mmcblk0p1 on /sdcard type vfat (ro,dirsync,nosuid,nodev,noexec,uid=1000,gid=1000,fmask=0711,dmask=0700,codepage=cp437,iocharset=iso8859-1,utf8)
I can't use the camera and the ringtones because of that.
I do able to remount the /sdcard as rw but any time I reboot the phone it become ro.
can you please copy for me the output that you have from mount command on /sdcard/ and the permissions you have on that directory from ls -l command?

I suspect the fat partition on your sdcard got corrupted. Try a reformat
you were right thanks
I did chkdisk from windows and it did fix the fs.
now its working just fine...
My captivate is already rooted, i use the Astro app to edit files and now im trying to edit the /system/etc/gps.conf, but when i try to save...does not save...i notice this file is read only rights. How can i edit that and save it???
to mount /system as read write, you need to be rooted (obviously) and open up an adb shell.
mount -o rw /dev/block/stl9 /system
depending on what kernel you're running and what filesystem /system is mounted as you *may* need to specify the filesystem ("-t vfat" for rfs, "-t ext4" for voodoo) but I've never had to before.
I installed the ubuntu dual boot and now want to get rid if the ubuntu partitions it created.
Anyone know how to do this?
Well, how about opening a terminal under android (terminal emulator by jack pavelich should be fine) and typing "mount" for checking mount points.
Then you could mount the partitions (e.g. "mount -o remount,rw /dev/sda2 /Volumes/useless)
---> This would mount the partition "sda2" as read-write on "/Volumes/useless/" in your android root directory.
Then delete all files on that dir. And google somewhat for further information on how to delete partitions.
Hope this helps.
NVFlashing over everything is probably the easiest
I fixed this by nvflashing the stock rom.
I'm looking for a one click solution to mount the external sdcard.
I searched the market for a widget without luck.
I don't like to go to the settings/storage all the time.
Try adding a quick link icon to the command: su - c mount ... etc., with all the arguments you need for your card, e.g.
su -c 'mount -o rw /dev/block/vold/179:17 /mnt/mSD'
(just change the volume)
I'm not rooted.
