changing permissions on folders??? - Hero CDMA General

Is the only way to change the permission of a folder through root explorer?
I tried connecting my phone to my pc and then using the adb shell command and then issuing the chmod 755 system/xbin but i got an error message that says "read only file system"?

Did you turn on "mount r/w" at the top of the page?

Exactly, turn mount r/w on using the button at the top. Then to change the folder permissions long press the folder and select the permissions tab.
For using the chmod command, while in adb shell you would have to type out "su" then "mount -o remount,rw -t yaffs2 /dev/block/mtdblock4 /system" so it won't be read only anymore.

A little guidance please (delete permissions, etc.)

(Sorry for not posting actual links - the system won't let me because I'm still a "new user.")
I already rooted my Sprint Hero using this (thread 583291) guide and can successfully tether using the WiFi Tether app. Yay!
Now I want to delete and/or replace the boot up sound (boot.mp3 located in /system/media/bootscreen) When I try to delete it right now (either through adb shell on my computer or from within a file manager app on the phone itself) I get permission denied or "read-only file system."
I see two threads regarding busybox, superuser, and adb remount. Thread 591303 which is dated 11/28/09 and is just for busybox and Thread 593952 which is dated 12/03/09.
I'm not sure which of these two I need to install. If it's the latter which includes ADB remount and superuser as well as busybox, then I'm not sure if I am supposed to unzip them before pushing them to my phone.
Could anyone point me in the right direction based on what I want to do (delete files on my phone - ANY file I want)?
Thanks in advance for any help you can offer.
All you should need to do is:
Code:
adb remount
rm /insert file path/file
So yours would be
Code:
rm /system/media/bootscreen/boot.mp3

will rm work without busybox?
As long as you can shell into the phone it should work. The rm command is to be run inside the shell.
So it actually should be
Code:
adb remount
adb shell
rm /system/media/bootscreen/boot.mp3
You want to install the busybox remount and superuser Rom if you want to run stock.
Or manually install busybox, superuser whitelist and adb remount
Biggz - looks like they are on stock. No adb remount.

Unfortunate, custom is so much better.
If you are on stock, do this:
Code:
adb shell
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
mv /system/media/bootscreen/boot.mp3 /system/media/bootscreen/boot.mp3.old
exit
[you can also do rm /system/media/bootscreen/boot.mp3 instead]

successfully removed (rm) the boot.mp3 in the shell - Thank you for that. I do want to replace it with a different one (I'll use the same file name since the .xml file still refers to it) so I'll need the cp command and I've noticed that it's missing in shell. I'm assuming I need to install busybox to get this functionality. I'm not really sure I want to install a complete new ROM and I don't mind manually installing busybox, adb remount, etc. What does installing "superuser whitelist" and "adb remount" allow me to do? I'm not sure what their potential uses are?
I installed busybox and have the cp command functionality now (see above post) but now when I try to copy anything to the /system/media/bootscreen folder I get "cp: cannot create '/system/media/bootscreen/boot.mp3': Permission denied"
I type "mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system" after getting into shell and typing "su" and getting the "#" prompt and it takes successfully (this is the only way I was able to actually "rm" the original boot.mp3 file to begin with.
See anything I'm doing wrong?
Nope, that is correct.
/system is normally mounted as read-only, so you can't add or delete anything. The mount command remounts it as read-write, so you can modify it as root.

Superuser whitelist is an application that warns you and asks for you to provide permission whenever an app tries to use the su binary to run as another user. You want this, as without it there's no way to know if an application runs as root.
Adb remount is a service that allows you to toggle the +RW bit on the /system/ partition through the shell. IIRC the one one floating around also kills color terminfo so you don't get all the extra chars on a windows PC when using the ls command. Just a matter of convenience.

I can't create/copy anything after getting into the shell and remounting as read-write. From CMD prompt I type:
adb shell
and get:
$
Then I type:
su
and get:
#
This is where I type:
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
Then trying to copy anything into the /system directory gives me:
Permission denied
It will let me DELETE anything I want from this folder (as confirmed by now deleting boot.gif just to check) but it won't let me cp (copy) anything to this folder. WHY?
What the heck?
try these commands for the boot mp3
Code:
cd/
cd /androidsdk/tools/
adb shell
su
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
exit
adb push directoryonpcwhereyourbootmp3is /system/media/bootscreen/
make sure that you rename the mp3 to boot.mp3 or it wont work anyways.
the other option (this is what I do) is find a bootscreen that you like (I use this one). open the zip file useing winrar or 7zip, navigate into the files where you see the boot.mp3 and drag in YOUR (now renamed) boot.mp3 close the window, put the zip file onto the root of your sd card, boot into recovery, choose flash from zip, flash the file and your good to go.

tried this just now and still get "failed to copy 'C:\android-sdk-windows\tools\boot.mp3' to '/system/media/bootscreen/boot.mp3': Permission denied"
It's the /system folder... I can push to /data/local all day long, but anything in the /system folder is read only. How the hell can I change this?
/system/media/bootscreen/boot.mp3

if this is the code you are using then that could be your issue
the code line should look like this
Code:
adb push C:\android-sdk-windows\tools\boot.mp3 /system/media/bootscreen/
doing adb push C:\android-sdk-windows\tools\boot.mp3 /system/media/bootscreen/boot.mp3 says that you are trying to push the boot.mp3 to the directory bott.mp3 and there is no boot.mp3 directory the folder where you want the boot.mp3 is bootscreen. try the ubove code and see what happenes.

Nope, was a typo on my part (here in the post, not when issuing the command). Still permission denied. I don't think it's actually mounting the /system folder as writable. Is there a way to check after issuing the remount command?
A quick command of "ls -l" at root prompt gives the following for the /system folder:
drwxr-xr-x root root 2009-09-21 06:30 system
after you run the remount command what does it say? does it say remount succeded?
After typing the remount command it simply repeats my command back at me and returns to the "#" prompt.
honestly at this point what I would try doing is do a back up then flash a custom rom like fresh 1.1 that has all the tools built into it. then go into the cmd prompt and cd to where sdk is then type adb remount and see what it says then adb shell and try to cp the file to that directory.
this is more a test than anything else.

I'll try this - so you recommend trying fresh 1.1 then? I know it's just a test, but just in case I like the ROM and decide to stick with it, might as well try a really good one! I'll try this tomorrow - I'm beat! (Thanks again!)

[Q] 1st update froyo

should i flash it. i dont have root
WOW! i cant believe no one has replied to you.
if you take a look at the first post with the topic
[ROM] Official AOSP 2.2 OTA
but you mentioned you dont have root. so try installing alogcat from the marketplace and capture the whole deal. then you can email directly from the app.
logcat isnt going to do much, it prefetches the files, need to pull the update.zip from adb
ok, so i havnt gotten the notice yet.
but need a bit of help prepping for when i do.
i have the android sdk installed on my desktop, and can create a virtual device etc...
but when i open the cmd prompt and try to run adb devices it says it is populating a list but i see no results or no file created.
so i tried just running adb logcat and it stops at waiting for device.
any pointers. im running win7x64 ultimate
well, i screwed it up. i removed the usb drivers and set it to debugging mode and got it working.
so i am able to run adb shell etc...
once i get the notice ill be ready to do an adb pull
adb shell
su
cd /cache/
ls
adb pull /cache/<package_name>.zip .

but how do you know the new radio and spl update name?
you should get that by running su then "cd /cache/ ; ls"
right now i have
download-1.apk
downloadfile.apk
recovery
lost+found
so after it is precached i run that "cd cache/ ; ls" i should have another file or two in there
that would be the file you run adb pull /cache/*.*
a tad bit of help, as a test i am trying to do
adb pull cache/downloadfile.apk d:\
but i get
remote object 'cache/downloadfile.apk' does not exist
i also tried adb pull /cache/downloadfile.apk d:\
and get the same.
edit:
tried doing a adb push
D:\android-sdk-windows\tools>adb push d:\test.txt /cache
failed to copy 'd:\test.txt' to '/cache/test.txt': Permission denied
so i dont have permission to put anything there, which means i likely dont have permission to pull from there
D:\android-sdk-windows\tools>adb pull /cache/downloadfile.apk d:\
remote object '/cache/downloadfile.apk' does not exist
so i opened another cmd prompt and and did an adb shell
su
and i am su
so while the other window was open and i was su i tried the same commands again and got the same results.
edit2:
D:\android-sdk-windows\tools>adb shell ls /cache
opendir failed, Permission denied
so it is definately a su/permissions issue.
Are you rooted? If not use Universal Androot.

Here do this:
First if you have root, open up terminal or cmd prompt if you are on windows:
adb shell
su
mount -o rw,remount yaffs2 /cache
chmod 777 /cache
that will change the permissions allowing for read and write.
Now exit out of shell and just adb pull /cache/
That will pull everything out of the cache partition.
BAM!!! perfect!
i new it was permissions related. just couldnt figure out the "mount -o rw,remount yaffs2 /cache" part. might i ask you to break that down for me? at least the yaffs2 part.
thanks!
so once the update hits i am ready to grab the files.

So the YAFFS2 part of the code I put up there is designating the file system in which we are reading/writing.
YAFFS2 is the most popular and widely used format for flash memory.
please allow me.
yaffs2 is a filesystem type. /cache is of course the directory. -o is for option.
rw: read/write
remount: remount /cache again with new option.

Oh yeah and BTW, you can change the permissions back if you want after your done, otherwise I believe you can just reboot the phone and it fixes it, not entirely sure, I was trying to rewrite my default.prop to get adb remount to work with stock 1.6 rooted, but I am getting and access denied issue.
perfect was about to ask what the -o was but i tried mount --help and mount -h both resulted in nothing. then you reply sharpt71
thanks again all.
i am now ready to pull the update and upload once i get the update. hopefully soon!
Rather than the remounting and chmoding so you can adb pull.
You could probably get away with
Code:
su
cp /cache/<whatever> /sdcard
Then mount the SD card or put it in a card reader.

You probably could I just know that this is a sure fire way to grab everything in cache directly to the machine, otherwise if you aren't next to a machine you could probably do a copy like you said.
My 2nd update failed, do you guys think the files are still in my cache?

[Q] Some system maps

Hi Every body,
In quit new in Android.
I just finaly rooted en S-Off my Desire.
Now I want to copy a file in to a system map, but I cant safe in that map.
Is there a way that I can Chmod the right, so I can Copy too their.
Check the file system you're trying to copy to, it might well be mounted as read-only. If you have permanent root you should be able to remount it as read/write.

No, you need to remount the /system file system (/system/media/audio/notifications) is just a directory within that file system.
Then go into that directory and make any changes that you need to. Then remount it as read-only when you're done.

The problem is ES File Explorer isn't running as the root user. So you can do a "chmod 777 /system/media/audio/notifications" then it will work.

Are you not comfortable doing it via the command line ? There is an "experimental" option within ES File Explorer to let it run as root, but I just tried it, and it doesn't work on the stock ROM.
I checked and it looks like one of the other main explorers, Astro, doesn't work as root either.
Maybe try the Root Explorer app (hmm, though I see you have to pay for it) ? Anyone else have recommendations ?

If you are willing to pay for the "Root Explorer" app, which you will find on the Android market, then that should do what you want (i.e. give you a file explorer app that will work as root).

Help ADB Push to /System Folder

Hope this is the right place to post this.
My Atrix is rooted stock 1.83 .
I'm trying to "adb push" some OGG files to "/system/media/audio/" to add-to and replace some of the existing system sounds, especially that bloody annoying keypress (typewriter) sound, but I'm getting the following error (which makes sense):
Read-only file system
Tried using Root Explorer, same issue...again makes sense since its mounted as Read only on boot.
I tried booting into recovery mode, but I can't access the phone via ADB at all, even with USB Debug enabled. I also tried "adb remount" command, no luck either. I get an error "operation not permitted".
So, does anyone know the correct sequence of commands I need in ADB to remount the Atrix /system folder as RW??
What I have been doing is using adb push to the /sdcard then using adb shell then su then
mount -t rfs -o remount,rw /dev/stl5 /system
Then cp /sdcard/whatever /system/media
Sent from my MB860 using XDA App
EDIT: im at my computer now so I can write this easier to understand, lol
Lets say the file you want to change is called whatever.ogg
Code:
adb push whatever.ogg /sdcard/whatever.ogg
adb shell
su
mount -t rfs -o remount,rw /dev/stl5 /system
cp /sdcard/whatever.ogg /system/media/audio/notifications
when you access root explorer, does it let you know that it has been granted supervisor privilages? Does it give you the option to change from read to write? what did you use to root? I had to run the original Aroot three times before if finally gave me root.
You're the best, worked perfectly Can't believe that hideous typewriter sound is gone, it only took me 1.5 years as an Android user to finaly say enough is enough. Whomever thought it was a good idea to mimic the sound of an 1800's typewriter on a 21st century device needs to be fired.
Thanks again.

I cant mount system rw

Hi. Im running stock 7.1.1 and i got tired of google now launcher. I downloaded the pixel launcher but couldnt swipe left for google now. This is caused because the app is not system mounted. So i flashed twrp but it didnt stick,after 2 weeks of trying difrent ways to do it and giving up a few times i saw a post that said i have to root after the flash or it wont stick. Ok i now have a rooted 7.1.1 with twrp and i can do what i want.. or so i thought because i cant mount system rw and cant set any app to system. I tried one click app and adb. My friend tried to mount it through twrp terminal but it shows that system is empty. I saw some posts about it that said that there were 2 system folders, one mounted by twrp and second one that actually is system and cant be accesed. Right now febuary OTA security patch is rolling in and i downladed flash wire to update but it crashes on encrypting. I think that this problem is caused by the same thing. Can someone give me some instructions to mount that damn thing or am i doomed forever? ;_; sorry for my english and my noobish explanation btw.
Download and install BusyBox and a terminal emulator app if you haven't already. In terminal emulator type "su" without quotes then press enter to give it root access. On the next line type "mount busybox -o rw,remount system" also without the quotes and press enter. If you did it right it should just go to the next line without any errors. Doing this should give you rw access to system.
