Rooted Hero Fails adb remount, can't move files from SD

I rooted my hero last night and tried out a few different ROMs but eventually decided to revert to stock and make some manual changes. I used nandroid to restore to just after the root (1.56.651.2). I was able to remove some apps using adb, but the adb remount command fails (permission denied), and I'm unable to push a new bootscreen on to the phone. I also tried a Root File Manager and pre-kitchen as alternatives for the bootscreen, and neither one works. The Root Manager won't paste the files from SD into /system/media/ and pre-kitchen just reboots the phone.
Any suggestions?

Any chance this has something to do with downloading only up to SDK Platform 1.5? I'm at a total loss. I RUU'd my phone, did a clean root at startup using adb shell, and I still have the same problem. The adb remount command won't work, and I can't push anything into the system directory. For what it's worth, when I still had Root Manager installed I was able to toggle RO R/W in any directory with no problem, and I could move files around within the ROM... but I couldn't move anything into it from the SD. I'm new at this, so I have no idea what the problem might be. Anyone else had this problem or have any suggestions?

If anyone else runs into this problem, this solution worked for me:
adb shell
# su
# mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
# chmod 777 /system (Or any subdirectory you want to push to inside system)
# exit
adb push <local file> <device location>
Restore modified permissions when done.
Though I'm still not sure why this is necessary in place of adb remount.

I'm pretty sure the adb remount command will not work on the stock rom. You should be able to do it with just this command instead:
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system

Thanks... didn't realize stock wouldn't accept adb remount. If I use the above line from within shell, that doesn't help me push anything on to the phone though... so I needed to enable global permission and then do the push. Oddly enough I tried the same approach last night using Root Manager, and the transfer from SD still failed, even after I applied 777 to the dir I was trying to modify. The current solution may be kind of tedious, but at least it works.

you really shouldn't do 777 on your filesystem, ANY app can then write to your system, overwrite things, or install malicious code. Just remount manually and you should be able to push anything you want, just remember that w/ the stock rom you also don't get a full busybox either.

I'm not positive, but I would think after you remount, you should be able to "adb push" to /system. I suppose it might be specific to that shell, but I would think not.
You just may have to do it once each time you boot your phone.
Edit - err nevermind... you're having permission errors.... um... change adbd on the phone to run as root? not sure how off the top of my head...

Remount Failed: Operation Not Permited

Hey guys. I've done commands in adb many times. I'm still new to it, but I never remember having this issue.
I've ran CM6 for months, and nightly's as well. I'm running a custom compiled CM6 right now though.
adb remount I get
remount failed, operation not permitted.. and in default.prop ro.secure is set to 1. I changed to 0 but still can't do remount. Any other suggestions?
Thanks!

For a workaround, try remounting through shell - mount -o rw,remount /system, or the full command (mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system).

is that a temporary fix, or for good. or just a work around?

Just a workaround. It's a command in OS itself that does the same job as "adb remount" - which is, remounts.
I just can't think of anything that would cause adb remount to fail, so I have no suggestions for you to try. But in case you want to be able to do something without getting stuck, and wait for the solution without being in a hurry - I've posted the workaround.

I don't have a solution to solve it once and for all, but every time you want to remount, use
PHP:
adb root
before your commands

excellent.
adb root
adbd is being restarted
adb remount succeeded .
Thanks dude! that will work for now til cooker fixes that. lol

Tried this and it appeared to succeed but I didn't get the results I wanted.
After doing this I tried push c:\com.amazon.mp3.apk \system\app\ and it repeated it back to me, but when I look in that directory, it's not there. What am I doing wrong?

Wrong direction of slashes:
push c:\com.amazon.mp3.apk /system/app/
And you shouldn't be doing it from the ADB shell. The remount is done in the shell, the push is done outside of it.

So once I perform the remount I exit out of the shell?

operation not permitted.

"adb push" gets you "not permitted"?
try "adb root" first, as suggested above.

adb root gets me something along the lines of "not supported on a stock build."
EDIT
ok...
adb shell
su
mount -o rw,remount /system
then i get this:
Usage: mount [-r] [-w] [-o options] [-t type] device directory
So it appears it's not actually registering the command?
Then I try
push c:\com.amazon.mp3.apk /system/app/
and I get: failed to copy 'c:\com.amazon.mp3.apk' to '/system/app/com.amazon.mp3.apk' : Read-only file system.

You need to use the full command, since you're running sh, not bash.
Look for the full command in my post.
Yes, currently it doesn't do a thing.

So I tried the full command and exited out to "dos" command prompt and tried again. This time I got "failed to copy.... ....permission denied."

Ok, try without exiting. I'm not sure it'll do anything useful, though.
There is some problem with either your ADB setup or the ROM you're using. Or you're just not rooted.

Found another thread on another board. I just flashed amon ra's recovery and booted up from there, and it appeared to let me copy!
But then it wouldn't let me cd to system/app. It let me cd to system, but not to app. Weird... I booted back up and there's no evidence of the "copied" apk, anywhere.
What...
the...
****.
Thanks to all for your patience with my super-noobish ass, I'm hoping you're not as frustrated with me as I am with this.

When you're in the recovery, your system isn't mounted. You need to mount it first.
Use almost the same command as for remount, but leave out the "remount" option. Just "-o rw".
Your copy went to void.

Why isn't there a link somewhere to a simple instruction manual? It would be so much easier if I could read up on this myself without bugging all of you guys.

Of course there is. My sig has it in bold, and you can find everything there. It's just that people tend to rush asking questions instead of reading

I've seen a couple of the basic noob guides to adb and I've seen the google definition of adb functions but it doesn't include instructions on how to do the stuff you're walking me through.
Will take a look at those links shortly. Btw, I'm on a MT3G though I don't think that makes a difference at this level.

My first script!

So I got sick of typing
$su
#mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
#chmod 777 /system
So I wrote a script and I just click on it in gscript.
Does this officially make me a white belt, lowest rank possible dev? Aahaha

Congrats on the script! It's get's easier now that you have the concept - then it gets hard again lol.
While we're on the subject of scripting - any reason you choose that system rw mount script? There's 3 ways I've seen it done and they are all completely different... maybe the have different functions?
Again, good job and I like your idea. I saves a lot of typing especially with those commands since we type them a lot.

I think just by writing a successful script.. you are already above MANY xda users.
Kudos.

His script mounts the system as rw.

Nice script
What I do is a little different. I have it saved as my initial command for terminal, so it starts whenever I use terminal.
The code I use is this:
export PATH=/data/local/bin:$PATH
su
mount -o rw,remount /system
I am obvlious though as to why you put yaffs2 and mtdblock3 and all that, I never thought it was necessary since it works just fine without it. I'm not too keen on linux syntax though so its probably obvious but I'm curious anyway.

That's what my question was too lol. It's a great script especially for his first but now he should make it less bulky. If it's being ran in terminal as a script then all he would really need is this:
Code:
#!/system/bin/sh
mount -o remount,rw /system
I don't believe you need to use su before running it but I always do just in case.
Of course you'll want to make a /system ro script (unmount) too so you're not always in mounted in rw access.

I found that leaving out the yaffs2 etc didn't work. I read somewhere that you need this line with certain kernels. I wish I could give you a more learned answer though.
I'm thinking it's a good idea to put the system back in ro too, actually. Now I'll have made two scripts haha
Sent from my HTC Vision using XDA App

Not positive on all of this, so someone can correct me if I'm wrong, but
Code:
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
is used to mount system by accessing the NAND (hence the yaffs2 filesystem and mtdblock device). Many of the older Android guides use this command (since the older phones all used raw flash).
The Vision (and many of the newer phones) use an eMMC though, which has an FTL to present the NAND as a block device to the OS (just like a hard drive). This is why in many of the guides written nowadays, you'll see something more like this:
Code:
mount -o rw,remount -t ext3 /dev/block/mmcblk0p25 /system
This accesses the eMMC as a native block device (hence the ext3 filesystem). This is probably the "more correct" way of mounting the partition as it utilizes the actual FTL controller on the NAND as opposed to the more inefficient linux virtual block driver (what mtdblock does), so it's a little cleaner from a software development standpoint. Both commands accomplish the same thing though, so you could really use either.
The shortened form of the remount is what others have been listing:
Code:
mount -o rw,remount /system
Basically, since the system partition had already been mounted by the OS on boot, it should already know the proper way to remount it (i.e., you don't have to retell it the device or filesystem used). I don't believe this command will work on every ROM out of the box though (requiring either Busybox to have been installed or ro.secure=0 to be set in your default properties, maybe both).

Excellent and informative post! So is the reason why the
Mount -o rw,remount /system
Command doesn't't work for me is because busybox isn't installed? I'll test this out right now...
Also, I was thinking chmod 777 might be redundant because the system is already rw. Is this true? My understanding is the chmod 777 simply sets whatever path after it as modifyable. Is there a difference between rw and being able to modify files in linux?

Well if you want to know if you have busybox just do this:
Code:
su
cd /system/bin
busybox
That should start busybox. It will say 'not found' if you don't have it - so if you need it the easy way is to use titanium backup to install it.
Btw, ianmcquinn that was very informative and well written. Thanks for explaining it so well.

Definitely have busybox. Definitely still just gives me the usage information...weird.
How do I set secure=0?
Sent from my HTC Vision using XDA App

ro.secure=0 is standard on most roms, so I asume you are just using a rooted stock build? You will need to unpack your kernel, change the ro.secure from a 0 to a 1, and repack the kernel. If you don't know how to do that, use this.

Virtuous 0.9.0
Sent from my HTC Vision using XDA App

I don't use Virtuous, but I would be shocked if it didn't already have ro.secure=0 set already. You can check by typing this in terminal:
Code:
getprop ro.secure
It should return a 0. This property is set in the ramdisk within your boot.img. To set it yourself, you would have to unpack the image, modify the setting in the default.prop file, repack the image, and then flash it back to your phone. As was said earlier though, pretty much all of the custom roms set this for you already.
Not sure what is going on in your case then. Maybe try running the mount command explicitly through busybox to see if that is the problem.
Code:
busybox mount -o rw,remount /system
If this works, sounds like you may want to reinstall busybox since the symlinks were not properly set up. Another thing maybe worth trying is to swap the order of remount and rw in the options. I've seen reports of this making a difference for some people, but have no clue why it should (maybe different versions of the mount command/busybox). Kind of a long shot. So try either of these commands:
Code:
mount -o remount,rw /system
busybox mount -o remount,rw /system
EDIT: In case you were curious, here's a link I had bookmarked about how to edit the boot.img. I'm sure there are others out there as well.

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

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.

[Tip] Make getting read/write access easier

If you are having trouble getting read/write access, try the following code in either Terminal Emulator on the device or through 'adb shell' from your computer:
Code:
su
mount -o rw,remount -t yaffs2 /dev/block/mtdblock03 /system
That has worked for me without fail on multiple Android devices (Hero CDMA, NS4G, Sprint Galaxy Tab w HC, Samsung Moment). Obviously, you need to have Busybox/Superuser installed.
This is useful for removing stubborn, factory-installed applications (Sprint, I'm looking at you!). However, you need to type this every time you want get read/write access which can be very hard using Terminal Emulator and tiny soft keyboards on the device. One way around it is creating a simple shell script. One example is below. I named mine 'readwrite' but you are free to name it whatever you want.
Disclaimer: I am not responsible if this screws your phone up, blows your phone up, or makes your phone hate you. It usually is pretty safe but still proceed with caution and type commands exactly as shown. Your mileage may vary.
Code:
su
cd /system
cat > readwrite
#! /system/bin/sh
echo -n "Mounting file system as read/write"
mount -o rw,remount -t yaffs2 /dev/block/mtdblock03 /system
echo -n "Finished mounting system as read/write"
exit
Press <ctrl><d> when done. Usually, <ctrl> is Vol-Dn button on most devices. Check 'Special Keys' section within Terminal Emulator to be sure.
Now time to make the script executable. Type in
Code:
chmod a+rwx readwrite
To double check that readwrite is executable, type in
Code:
ls -al
The the first column of the row containing readwrite should read "-rwxrwxrwx"
Now, to get read/write access anytime you wish on the go, just type in the following in Terminal Emulator:
Code:
su
cd /system
sh readwrite
That should do it
PS: If you have Root Explorer, by all means use that. My understanding is that the application is not free. This tutorial is for cheapstakes like me

This isn't easy, this is pretty difficult for the noobs.
An easy way would be to download 'mount /system rw/ro' from the market, enable it to run after boot, mount rw and grant it su access. Now that's simple.
