I have stock Tattoo ROM. In addition I modified it to get root and installed busybox.
Now I want to make some modifications to /system filesystem. I go to adb shell, su, mount -o rw,remount. After that "df" says me that /system have some available space. But when I try to wriite something to this FS, it fails and then "df" shows me zero bytes available at /system.
What I have to do?
I think you must run insmod tattoo_hack.co also, to be able to white to system.
oh thanx. i forgot it....

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...
I am running custom rom Rooted 2.1 v0.3.
Ever since flashing to the custom rom, when i try to push a file, such as:
adb push bootanimation.zip /system/media
I get the error:
Failed to copy.... Read-only file system.
I didn't have this error before flashing to the rom. Does this have something to do with superuser whitelist?
I have tired:
mount -oremount,rw /dev/block/mtdblock3 /system
and it didn't work and I tired:
adb remount
winch returned:
Operation not permitted.
This is ticking me off since I didn't have this problem until flashing the rom.
EDIT: Now if I try:
adb push bootanimation.zip /system/media,
I get:
Permission denied.
This is crazy.
I need help also. Rooting for first time and trying to get recovery.img on and keep getting read only errors. Tried remount to no avail. Help please
su
mount -o rw,remount /Dev/block/mtdblock3 /system
file system is case sensitive!
if anyone know what command to execute an install or push of "any.apk" via Android Terminal Emulator. It would help me greatly.
p.s.
make sure you have developer mode enabled "settings" and accept su permissions. Also have BusyBox

I had the same problem. From what I could tell, I had the wrong ADB driver somehow. So I downloaded the drivers from the HTC website and went to device manager (Win7) and updated the driver software which fixed the problem. But I think i just lucked out when i stumbled onto that, I feel a blind retard with epilepsy trying to draw a circle on an etch-a-sketch when I'm doing things like rooting. But, it couldn't hurt to try it.

Did you ever get this fixed? I have the same problem!
I have the same problem also. I've been using SDK just fine for over a month or two, and now that I'm on V3, no worky. Somethings obviously going on. But what?!

I think the proper permissions were not set for this ROM. Hopefully jcase can modify the file and re-upload the ROM =)
at least that's what I've gathered... someone PLEASE correct me if I'm wrong
edit: I looked at the script file and it seems like rw permissions are set properly???
jcase - any insight?
I personally get a bunch of "Out of memory" errors when trying to follow the recovery walk-through.
post baleeted
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.
*anticipation*

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?
I can't mount r/w through root explorer.. I also tried mounting in recovery but it wont stick when the phone boots up.. anyone know how to do it?
assuming you have root, open a terminal and type the following
su
busybox mount -o remount /system
i am rooted, and i tried it.. still a no go on the r/w.. its not that big of a deal at this point i guess, just seeing if anyone knew what the deal was
my busybox won't update either.. saying i may not have nandroid backup or it was unable to remount..
my bad sorry. the second command should be
busybox mount -o remount,rw /system
awesome.. worked
Hello fellow xda'ers,
A few weeks I am experiencing a problem with my moto x style. The problem is that i don't have access anymore to my system folder. I have full root access, I can use rooted apps, but i can't switch my file system to r/w. Also when I boot into recovery I can flash roms etc, they are fully working, but once again, no system access. Also when I try to mount the system folder in recovery it seems it won't stick. Also when I use root explorer it says it switched to r/w but in fact it is r/o..
Can someone please hint me out what I could do to fix this problem?
Thanks in advance,
Bump
Have you tried something like this in terminal as root, or via ADB root?
Code:
mount -o rw,remount,rw /system

Did you receive an error running the command? You are root, correct? Possibly just use:
Code:
mount -o remount,rw /system
Then run...
Code:
mount | grep system
Mine is read-only, but this should tell you if yours is rw or not.
Code:
u0 a114 clark:/ mount | grep system
/dev/block/bootdevice/by-name/system /system ext4 [B]ro[/B],seclabel,relatime,data=ordered 0 0
