[Q] Hello there have some problems with moving system files

Hi i moved some files from system/app into the sd card to get some space so i could use the metamorph app but i didnt work so i was going to move back the files from the sd card to system/app but now they wont move there anyone know a soloution how to do this?
thanks in advance

system is readonly
you must do an
adb shell
mount /dev/block/mtdblock3 /system
then you can fool around with your system apps

mount /dev/block/mtdblock3 /system || I wrote that but it says
"mount: mounting /dev/block/mtdblock3 on /system failed: Device or resource busy"
i rooted my phone yesterday quite knew to android and i have no clue what to do

You are doing that in recovery mode right?

I tried in ClockworkMod Recovery v2.5.0.1 but it says Device or resource busy :/ have no clue.

ClockworkMod has a nice green menu on screen from where you can see (partitions menu) which partitions are already mounter and which are not.
You can also do adb shell and run "mount" in it to see which partitions are mounted and in what way. ClockworkMod has /etc/fstab so you can mount system just by running "mount /system". If system is already mounted, you can cd to /system/app and try "touch test". If you get permission denied then your system is mounted read-only otherwise you will see test file in /system/app if you run "ls".

I did adb shell and did run "mount" and it says /dev/block/mtdblock3/ on /system type yaffs2 <ro>
I downloaded a app called root explore and the main reason for that was so i could move some files from system/app so i could get some free space so i could use metamorph that was my plan and i moved some files i have eard you could move that wouldnt harm anything but it wasnt enough free space, so my plan was to move back the files i had moved into the sd card some went great but i have like 4 files that i cant bks it says "You cannot paste here because the file system is read-only" is there any other way to push those file into the system/app again? have tried the things u wrote up.
And im not a very pro of theese things i started with this yesterday so excuse me for being stupid!

This:
/dev/block/mtdblock3/ on /system type yaffs2 <ro>
...means that system is mounted read-only (mind that "ro" at the end).
Try running "mount -o remount,rw /system". If it doesn't help run "cat /etc/fstab" and post here the output. You need to be in recovery mode while doing this of course!

did "mount -o remount,rw /system" and it said mount: can't find /system in /proc/mounts
and the other one said
/dev/block/mtdblock4 /cache yaffs2 rw
/dev/block/mtdblock5 /data yaffs2rw
/dev/block/mtdblock3 /system yaffs2 rw
/dev/block/mmcblk0p1 /sdcard vfat rw
/dev/block/mmcblk0p2 /sd-ext auto rw

used my brain a little now and in the recovery settings i did mount the /system in the menu and now i tried to write cd /system/app and now in the cmd it is like this "/system/app #" anything useful?

Sure... as I already told you try to run "touch /system/app/test". This command shoud make empty test file in /system/app. If you get permission denied then you have read-only system. If it suceede, then your /system is writable and you can see all the contents of /system/app by runing "ls".

I wrote that and it wrote the same
"touch /system/app/test"
no permmission denied then it may have worked?

i checked and there is a testfile in /system/app now

I think i got it to work now thanks man for all your help!

factory.zip to mmcblk0p3

I am pretty sure my factory.zip is corrupt or nonexistant from my mmcblk0p3. How do i move the factory.zip file over there from this thread http://forum.xda-developers.com/showthread.php?t=919353
Thanks

I just did this last night. First I booted into clockwork recovery and hooked up the nook to my computer and started up adb. I tried doing this when it was booted normally but I could not mount mmcblk0p3. Anyways once you are in recovery mode go to where adb is installed. Then these were the commands I did
Code:
adb shell mount /dev/block/mmcblk0p3 /emmc
adb pull /emmc/factory.zip factory-1.0.0.zip
adb push factory.zip /emmc/
The second line is me backing up my old 1.0.0 factory zip, just in case things went bad. Then I did the 8 failed boot reset and then reset /data

Thank You! I had something like that except i was missing emmc in the first line and i couldn't figure out why i couldnt mount mmcblk0p3. I want to make a how to once i reach 10 posts on this.

Hate to bring back an old thread, but, no matter how I have tried, I cannot mount /dev/block/mmcblk0p3... I always get invalid argument error... any help is appreciated.
>adb shell mount /dev/block/mmcblk0p3 /emmc
mount: mounting /dev/block/mmcblk0p3 on /emmc failed: Invalid argument
I have yet to be able to mount mmcblk0p3 to copy factory.zip to it.... hoping this would fix my install failed error on the 8 failed boot install.
NM.... fixed it... had to mke2fs /dev/block/mmcblk0p3 before I could mount it... got it fixed... the 8 failed boots works as it should again.

[Q]: Read-only filesystem

Hi!
I have rooted my phone (LG Optimus 2X) and mistakenly deleted some files.
I have these files, and want to push them back using adb, put my problem is, that when i try to mount the system in read / write mode using "adb remount" i get this error: "remount faileded: Operation not permitted".
I can't figure out how to fix it, i can pull files etc.
I have also tried to use the adb shell, and copy the files from the internal sdcard, but i'm getting the same error.
Only read-mode.. :/
Anybody who can help, fixing this problem?

If you want to mount /system just write:
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
Then you're good to go

[Q] CWR Error: Can't mount /cache

I get this error in CWR (3.2.0.1), I have a nook with a blue sticker:
Code:
E:Can't mount /cache/recovery/command
E:Can't mount /cache/recovery/log
E:Can't open /cache/recovery/command

Nothing, and I mean Nothing I have found in this forum solved this error, including the repartition-boot-stock+factory rest.
Any help guys? I am desperate!

adb is working but shell is not
This is what I got, anyone has an idea how to recover from this?
Code:

If you repartitioned, that may be the reason the adb command is not working....

So I have 2 two problems in which the solution to one causes the other...
In the mean time I manged to run both the Froyo and HoneyComb from the sd card, but not the CM7 (which is the one I am trying to install on the internal memory)

using ADB to restore
I tried to use the methods described in:
:http://forum.xda-developers.com/showthread.php?t=919353
However it is not clear where should the factory.zip go?
for some reason it also says that the /dev partition is only 244MB so I cannot flash the system.img, it is probably the partition in the SD card and not the memory, so not much advancement here either. I also think that because it gives me 11223344556677 as the S/N and not the real one.
The quest to restore the nook continues...

Is there a way to manually repartition through ADB?
or anything? cause nothing solves the first error posted in this thread

factory.zip and rombackup.zip should be located on /dev/block/mmcblk0p3
system should be written to /dev/block/mmcblk0p5
1123344556677 is normal for the device listing when adb'ing in when running CWM on the uSD
to write the img files you need to use:
dd if=(IMG FILE ON SD) of=(PARTITION ON /dev... i.e. /dev/block/mmcblk0p1)
to help you out...here's a list of what goes where:
mmcblk0p1-boot.img
mmcblk0p2-rom.img
mmcblk0p3-factory.img
mmcblk0p4-logical.img
mmcblk0p5-system.img
mmcblk0p6-data.img
mmcblk0p7-cache.img
mmcblk0p8-media.img

problem:
thanks for the reply, I am studying more about andriod and adb now than during all my bachelor's.
just
adb push factory.zip /dev/block/mmcblk0p3 ??
and
adb shell dd if=/sdcard/boot.img of=/dev/block/mmcblk0p1
(in some places I saw they didn't write "/block")
and where is rombackup.zip from?
the problem is that for some reason /dev/ is only 244MB so I can't dd system.img, only the boot.img.
I wish that somewhere in the world would exist something that solves it from CWR, just some zip I would install to fix boot+factory+system in one stroke...

to get factory and rombackup zip files on mmcblk0p3...
adb shell mkdir /sdcard/tmp3
adb shell mount /dev/block/mmcblk0p3 /sdcard/tmp3
adb push factory.zip /sdcard/tmp3
adb push rombackup.zip /sdcard/tmp3

more problems (desperation is looming)

then I would use
mount rw /dev/block/mmcblk0p3 /sdcard/tmp3
If that doesn't work:
mount rw -o remout /dev/bloc/mmcblk0p3 /sdcard/tmp3
but it would appear something else is amiss... since it even shows the command should have worked... since everything other than the command (mount) the device (/dev/block/mmcblk0p3) and directory (/sdcard/tmp3) are optional parameters

[Q] Can't mount internal sd card

Hi everyone,
I have the famous problem described here http://forum.xda-developers.com/showthread.php?t=1253036
So I'm trying to repair my internal sd card with these
Code:
adb shell
mount /sdcard
su
parted /dev/block/mmcblk0
rm 1
rm 2
rm 3
quit
With "mount /sdcard" I got "can't find /sdcard in /etc/fstab"
With "su" I got "Permission denied"
With "parted /dev/block/mmcblk0" I got "parted: not found"
I have flashed a JVP ROM with speedmodkernel and CWM v2.5.1
Help Please!!

Do you have a terminal program on your phone? Maybe you can try to connect to localhost and try from there.
Because of the Permission denied message: your phone is rooted?

I don't have a terminal program on my phone because I have a boot loop issue, so I can only get to download and recovery mode.
From CWM v2.5.1 I've done "Advanced SpeedMod Features" --> "ROOT / Install Superuser" --> "Simple: install busybox+su" so I think my phone is rooted
