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...
(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!)
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?
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.

I agree this is not the easiest way to do it but is just another option. I for one hate installing applications if I can get the job done myself

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.
