Did you check it is r/w and not r/o?
Have you tried superclick?

You need to use something like Root Explorer to do that.

btw i try to run desktop virtualizer and also this program said that she dont have the right permission do to so. :<
thanks for your's help , mate ! :]

Do you have SDK installed? If so, just open up a command prompt and use:
Code:
adb shell
mount -o rw,remount /system
rm *insert path to specific file you want to remove*
Ctrl+C
exit

[Q] Honeycomb Keyboard

I'm kinda new to android
I've started to delete useless apps through Titanium Backup(acer staff,games etc) , and exidently deleted smth connected with honeycomb stock keyboard.
Now every time when i want to use stock keyboard, pops up a messege "The application Android keyboard (process com.google.android.inputmethod.latin) has stopped unexpectedly. plz try again".
Ive tryied to reset factory data but it wont helped. Is thera any solution for this problem? if there no, plz tell how to completely reset tablet) ive read "system Images " thread but i didn understand some things
here is my recover steps: (for a500 which is bricked)
for a500 is normal:
root it
put the system.img into a500
connect to the computer with adb and follow the codes:
su
dd if=/sdcard/system.img of=/dev/block/mmcblk0p3
then reboot
Click to expand...
Click to collapse
connect to the computer with adb and follow the codes:
su
dd if=/sdcard/system.img of=/dev/block/mmcblk0p3
what that means)

You might very well have ruined your tablet.
I'm not a developer or coder so I can't make any sense of the code you posted but if a reset didn't fix it then you've certainly deleted something important. Hopefully someone has some ideas.
If not, then maybe you can return it? And next time, don't delete something unless you know what it is you're deleting.

ok ive recovered from image, but now wifi is not working , what should i do?

There are posts about having to change file permissions to fix wifi. Search this forum, there are a few.
edit - linked post
http://forum.xda-developers.com/showthread.php?t=1074449&highlight=wifi+permission

yeah ive read this but i dont know how to move that files to system folder on devide, wifi is down , so i cant download any file managing apps from market and theres no any file managers on stock Rom

If you've got the adb working, you can use the command mv to move the file.
I'm not sure of the exact path involved, but for example. the file is in /mnt/sdcard/filetobemoved and needs to go into /sytem/lib/modules
mv /mnt/sdcard/filetobemoved /system/lib/modules
That'd put it in the location you need. To change the permissions, you'd use the command chmod
chmod 655 /system/lib/modules/filetobemoved
The 655 is an octal(0-7) representation of the file's permissions. I'm not sure what permissions it needs, but you could try 655 as a start unless someone else knows for sure.
if you want, hit me up on msn, I can try to walk you through it: [email protected]

No clue. I really should start reading up on HC app development and at least familiarize myself with that environment.
I haven't rooted yet cause I'm e'scarded to.

ahh i cant replace that files , somehow installed astro manager(through docsttogo) but i cant remove/replace/rename that files in system/lib/modules it says i dont have permission to do this.
tryed in connectbot type "mv /mnt/sdcard/filetobemoved /system/lib/modules"
got this "failed on '/system/lib/modules/filename' - cross-device link"
im rooted what if

type mount and paste/retype the line that has /system in it. It might be mounted read only.
or try the cp command in place of mv
edit - also, the filetobemoved is just an example. I think one of the filenames is bcm4329.ko but I'm not sure. so /system/lib/modules/bcm4329.ko would be the full path

yeah thats i know)

Are you logged into the tablet using adb's shell? I've only used that once on a different tablet, but iirc the commands are standard Unix/Linux commands. Someone correct me if I'm wrong but aren't you already logged in as superuser like this? You don't need to 'sudo' or 'su' to switch over do you?
I'm not familiar enough with this specific environment to figure out what might be keeping you from placing those files in that location. The command to check the partitions mount options is
mount
It should return a bunch of text, one line of which is gonna be the /system partition. If it's ro(read only) then you can't write to it and would need to remount it.

yeah it looks like it is "ro"
ive got /system ext4 ro
how to remount)

My knowledge of adb is limited as well. All I know is that I can connect to it, type: adb devices (in the command prompt) to make sure it sees my tab then 'adb push filename.extension /directory/structure' to force files... Conversly, I think adb pull filename.extension /directory/structure will grab files on the tab if you know what they are called and where they are located.

what was the /dev/block/mtdblock for /system?
there is a number after it...for example /dev/block/mtdblock1
mount -o rw,remount -t ext4 /dev/block/mtdblock1 /system
would remount it read/write, provided that it is mtdblock1, change the number depending on what your device has.

yeah now /system have "rw", but it anyway refuses to copy using mv(failed on '/system/lib/modules/filename' - cross-device link"
) or astro manager

If cp won't put it there either, I'm out of ideas. Maybe ask in the other thread how they were able to copy/move the file and set the permissions?

I know it may not be really classy, but how about downloading an .apk That will let you mount the drive, to an sd card in a computer then transfer that to the Acer. (If it's an extreme case and nothing else will work..not condoning piracy, but don't know what would work...)
or is it possible to copy the system data from a Titanium backup and send it over so he can restore the missing files?

This following step I can't be responsible for it's safety. It looks safe to my eyes, but proceed having been forewarned. I did some research and you might be able to use dd to get the file there.
dd if=/mnt/sdcard/filname of=/system/lib/modules/filename

Our on the right path so far.. But the way I've always used adb I kinda dragged everything to the tools folder...I have the library and everything else there...try putting it on our tools folder and see what happens if not check the platform tools.. Just drop the map apk and try it out.

You can make the system r/w.

lost all permissions after messing with platform.xml

Hello,
I have SM-N9005 variant and recently I updated to the latest android 4.4.2 leaked version with Odin, and then rooted with CF-Auto-Root.
After that, I lost the permission to write to external sdcard.
I searched and found this: http://forum.xda-developers.com/showthread.php?p=49603814
I backed up /system/etc/permissions/platform.xml and then I followed the instructions there.
After restart, a lot of app stopping messages showed and I had no access to file system or network anymore.
I used adb shell to restore the original platform.xml but it didn't helped in any way.
It seems that all mounts and networks are working, but none of the applications has permission to use any of them.
How do I resolve this, without wiping all my data?
Thank you!

You need to set the correct permissions on the .xml after you overwrite it back into the /system Off the top of my head I can't think what they are (just out of bed and got to work so still sleepy!)

I tried 644 and 777 but the problem persists.

rw-r-r which is 644 - read wrong
or chmod 666 -- forgive my lack of memory, it has been a long time since I have used chmod commands, few years since my glFTPD / site modding days.

i dont know if it helps in your situation but did you try the "fix permissions" from a custom recovery like twrp?
there are also scripts you can execute in a terminal, the knoxout script linked in my sig for example has a permission fixer included.

Do I need to mess around with something on Alsa Mixer? And what do you mean with the chmod 755 file?

You block the app, allow them in cm settings

It has already been mentioned on this forum quite a few times...
The best way to increase all volumes on CM11 is to install William's kernel and install Fauxsound. (see play store)
You can increase your volume untill the point you can literally blow your speakers.
Be careful when using it!

Is the williams kernel compatibile with last CM 11 compilation ? I don't want to break my phone . Is there another way to fix that by flashing kernel? This williams seems to have bugs

Though, if anyone follows this guide, use max volume at your own risk.

Keep it going bro! I'm too noobish to do anything like that, share when u achieve our goal .

Ok, if you want less volume, you need lower value in script (p.ej if is 96 you can modify to 94 and test it), remember always change permissions to 755 after change the script (Reboot required after change).
Digitall RX1 and Digital RX2 are for call speaker.
RX3 .. RX7 is for external speaker.

Could You tell me what exacly did you do? In simple language. I have this app aleamixer and i can find this rx digitals in it. I have already changed the volume of call speaker by switching values with 8x or 9x(it worked w/o restart) . I don't know what is this chmod and 775 permissions. I let this app permanent permissions in superuser.
I dont know how to change media speaker though :/. Could u tell me?

Extract the file that dssmex left and extract it. Put it in your /system/etc/init.d/ folder.
Go to Terminal and type:
"su" Do this only if you haven't given permissions to the app yet.
Click options and select restart console.
Now type:
"-c chmod 755 /system/etc/init.d/audio_80"

But do I have to mess sth up with values in this alsa mixer? Ok, nvm, i dont have to. I can't copy this file audio to this folder init.d though. It is a matter with permissions i guess which i cant changr

You can't? You need to have Root Explorer or any app that can access to the system folders.

Okey. I copied it finally... I thought that my explorers have this root permisions to copy. Anyway, when i write this command into terminal it says file not found ;/
-c chmod 755 /system/etc/init.d/audio_80
heh, i just read that this chmod is changing permissions status, which i did already(in some root explorer) so it should work now... i check it right now. It seems not to work ;/
OK. It works now, after restart. Ty all

Permissions should be. rwxr-xr-x
Good to know it helped.

Thanx bro.....
