I'm trying to push files to /system via ADB. However I'm having problems (getting permission errors). I am running Eclipse 2.0.2, so yes, my phone is rooted, I have su and busybox.
Phone is connected to PC and is set as "USB Mass Storage".
USB Debugging is ON
Here is my CMD log:
Code:
C:\android-sdk\tools>adb remount
remount failed: Operation not permitted
I tried to remount and it failed
Code:
C:\android-sdk\tools>adb push C:\myfile.apk /system
failed to copy 'C:\myfile.apk' to
'/system/myfile.apk': Read-only file system
I tried to push, and got a READ-ONLY FILE SYSTEM error (keep this in mind)
Code:
C:\android-sdk\tools>adb shell
$ adb push C:\myfile.apk /system
adb push C:\myfile.apk /system
adb: permission denied
I try to push inside of ADB shell. Nothing again...
Code:
$ su
su
# mount -o remount,rw /dev/block/mtdblock4 /system
mount -o remount,rw /dev/block/mtdblock4 /system
# exit
exit
I go into SU and attempt to remount the /system
Code:
$ adb push C:\myfile.apk /system
adb push C:\myfile.apk /system
adb: permission denied
$ exit
exit
I go back up to ADB shell and try to push again... same error as before
Code:
C:\android-sdk\tools>adb push C:\myfile.apk /system
failed to copy 'C:\myfile.apk' to '/system/myfile.apk': Permission denied
I go back to the main command line and try to push again. This time I get PERMISSION DENIED. This error is different than before.
Any help on the matter?
I've read about ro.secure needing to be set to 1, but I need to edit the boot.img in order to do this, correct? Does that require an unlocked bootloader? Is root ADB even possible on the DX2.
Thanks!
I am no expert (don't even know if i know enough to b called a newb) but maybe try a root explorer. I use es file explorer because it's free. In settings check root explorer and mount file system. I received similar errors and this solved my problem.

I'm familiar with root explorer, it's easy. I'm wanting to be able to use ADB though. Your post made me try something new though. I plugged my phone into my PC, then went into root explorer and mounted everything as RW. But, still was unable to push via ADB. Thanks for the reply though
So, how can I get ADB working?

I was using adb also and had similar problems. After i changed those settings i was able to push a file. I had to have system mounted.

No luck on my end :/
Sorry i couldn't be more help. I am new to adb and may have done more to get it working. I'm sure there's someone else around here that can help u out.

Make sure there are no spaces in the file path to your android-sdk folder. Can't say if this is your issue but its worth a shot as it has always caused weird problems with android development since day one.

Ro.secure is in your local.prop on the root of your phone. As far as your issue you have to reset permissions in order to push to /system. I saw that you were trying to do that but with no success. I believe I know what will help but I will have to find it and repost.

Ok look at the command lines at the bottom of the op. You are going to use adb shell. Follow that almost exactly but adjust according to your directories. Should go into adb shell, gain su permissions, mount /system rw, push your apk, then don't worry about remounting as ro, just reboot. Pay close attention to spaces.

Took me a few days to be able to getting around to trying this, but it didn't work :/ I'm still getting all of the same errors. The /system just doesn't seem to want to mount as RW (even though it is possible when using root explorer).
As for ro.secure in my local.prop, I'm able to edit this but it resets on reboot because (from what I've read) this is a file generated by the kernel
Anyone else have ideas?

Moon shadow has a post in development to mount system rw
It's some type of script u run before adb or something
I don't know anything bout adb
But I do know he created it for this reason
Check it out

Thanks for that! It's not quite what I'm aiming to eventually do, but did give me more insight on how the whole adb/shell/su systems work. From inside of su, I was able to mount the /system as RW, however I'm only able to do this from inside of SU. I want to be able to do this from the initial CMD so that I can ADB PUSH from my computer to the phone.
Here's my latest log:
Code:
C:\android-sdk>adb shell

So now the question is, how do I mount as R/W so I can use ADB push?
Wes
Maybe its because im tired but im confused as to why it wont let you push your files if you have remounted as rw. At that point it should be cake. You gained access to system by remounting it as rw successfully already.

Try:
Code:
adb devices
adb remount
adb push [filename] [destination]
adb reboot
the "adb remount" remounts the fs RW instead of the default RO.
I'm no expert in ADB, but I had run into the same issue as you and for me the fix was to go into ADB SHELL , then type SU to get SU access, then type exit twice to get out of shell completely. Then I tried pushing the APK and it worked fine with no read only errors.
This worked for me on my SGS2, could work for you ! Goodluck !

Any update
did you ever get this figured out? I'm having the same frustrations on mine. Mine won't install the 2.3.5 update due to it not recognizing the Quickoffice.apk and I'm trying to push the files manually, but I'm having no luck getting past the same you've posted here.

Do this
Sbf to 2.3.4
(or 2.3.3& take one ota To get to 2.3.4...however you want to do it..just be bone stock 2.3.4 )
Root your device.
BUT DO NOT USE ZERGRUSH TO ROOT
Use petes Motorola one click root method.
Then continue the process as normal from there on out.
Trust me in this. Zergrush root method is not playing nice with your /system partition, (if you notice during the root process it might say something like "making room in system,"= or "moving/deleting app to make room" something similar)
And when it does that, it's messing up how the update checks for untouched stock apps.
Let me know how it goes.
This solution has worked for COUNTLESS others so far, zergrush has always been the culprit when it comes to failing to find certain apk or system file that needs to be there for the update to install.

This won't work with Eclipse since it's not using 2nd init. I asked this question in the Eclipse forums and Nitro responded with the following:
Not without using 2nd init. All of that works due to being able to load its own init.rc which starts services and passes parameters, etc.. during boot time. It is possible to make a stock rom use 2nd init. CM9 will not even have root enabled by default. The only other way to push stuff is to enable root shell prior to pushing.

I know that CM7 allows using the adb remount, but that's because it's using 2nd init. I had also asked the question about why CM7 defaults to root shell when you adb shell into it and that's why he mentions how CM9 won't have root enabled by default.
The way I push to Eclipse is to run root explorer on my phone and mount the directory r/w. Then, I can use "adb push" to the phone.

I think I may have tried that in one of my iterations. Originally I had it rooted with One-Click and then I was having issues with the 2.3.5 OTA update (quickoffice.apk) and at this point I've SBF'ed and rooted it probably 5 times this week so far. Rooted with both One-click and zergRush at various times. Actually I think every time except this last time has been with one-click. So I don't think that has seemed to make a difference for me so far. I can try it again, but if there's any other advice to throw out in the mean time, I'll take it.
Alternatively, I may take the new phone (the first replacement they sent had 2.3.5 on it, but a bad menu key causing the phone to flip out), load Titanium Backup on it, backup all the system apps and restore them to my original phone. Worst case is I have to SBF it again. But that seems like a logical process since I will have two phones available.
I am trying to re-root after the 2.3.6 update, I did not remove root before the OTA update.
I made sure USB connection was set to none, and USB debugging was on. I see that is saying that I am out of space, problem is I don't know how I could possibly be able to be out of space, I have plenty of room on both the internal and external cards. Below is the output with the error. Any help would be appreciated. Thanks.

Hi there... I had the same issue when I installed the 2.3.6 ATT OTA update when I lost root... I tried RootKeeper application but it didn't work after the OTA installation. I looked for information about this error but didn't find much or complex solutions as to free space from that system dir... so then I thought about if the copy command would have an overwrite option and it did, so I tried it and it worked for me.... I'm rooted again!
I see this is an old post but in case you still need it, it may help you too. I used line bleow to overwrite and the rest you know it.
cp -f /preinstall/su /system/bin/su
by the way, I got an error in the line "PATH=/system/bin:$PATH pm install /preinstall/Superuser.apk" telling me that the application or file already existed as I already had superuser installed... I guess it should work without re-installing it, in my case the reinstallation was to a different superuser version... anyway if you want to skip that error and proceed with the re-installation you can use option -r as shown in line below.
PATH=/system/bin:$PATH pm install -r /preinstall/Superuser.apk
cheers!
avelezmtz,
Thanks for the idea, but it did not work for me, I still got the no space left error. Do you know if there a way to delete the SU file and then try to copy it? Thanks
I tried the, PATH=/system/bin:$PATH pm install -r /preinstall/Superuser.apk, command and it was able to reinstall the apk which it never has before so that's good, but it's still not rooted.
If anyone else has any ideas let me know. I am thinking about backing everything up and doing a factory reset and seeing how that goes.
First... as suggestion, if you will be playing deleting files, ensure you have clockworkmod backup or anyother way to restore a previous backup just to be safe.
I think rm command should delete su, but I'm not sure if it would help since the error is not a permissions error, so the ovewrite option should work if the space in the system dir is enough... if you still wanna try the removal of su I think line below will do it.
rm /system/bin/su
Another option I saw somewhere it was about freeing up space by deleting apk files from /system/app dir which is mounted in the same volume, however it would depend on how big those files are. Of course you should back them up first maybe copying them to /sdcard/ for instance. In the post I saw that they removed swype.apk and that was enough for them but in my case it didn't help and as the ovewrite worked I didn't try removing more apps.
If you want to know the space on that dir you can use
df /system/bin/
avelezmtz,
Thanks for all the help, I am now rooted again!!
Using your suggestion I deleted Superuser.apk and Swype.apk from the /system/app directory.
After that I was able to rerun all the commands and get root back. Thanks for all the help, I appreciate it. Sure beats wiping the phone and starting all over again.
I have a problem with my Yu Yureka which running on CM 12.1 and Rooted (su) twrp
1. When I was trying to to flash any zip file like CameraNext Mod, it was flash successfully. After reboot the system, I can't find the CameraNext Mod, it was not in menu.
2. Sometime when i tried to flash other zip file like xposed framework, it was not completely installed. there was error and the error message was " cp:write error: no space left on device"
plz help me with right direction..
I just play andorid device a few days, but My hdx7 is a little bricked because i deleted some system app. Now I can log in fire os, have adb, usb connected and internal storge, even i can operate device setting app, but i can't open the other app because i don't have a desktop.
I compare system/app folder with the same folder in the amazon bin, found that the folder lack of scores of app, but the other system folder is the same. So I hope can adb push app folder to the system folder, but the pemission denied. I try to remount or mount, it can't work.
if adb root, then "adbd cannot run as root in production builds.
if adb push apk to the app folder, then “permission denied".
if adb remount, then ”remount failed: Operation not permitted".
and I have try adb shell like that:
# su
# mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
# chmod 777 /system
# exit
it didn't work.
my hdx7 have rooted.
My Questions are:
1. If I could push the app folder to the system folder and reset to factory, is my hdx saved?
2. How to get the system folder rw in the situation?
thx for any prompt, although i am a rookie but i will try my best, i wish the adept can help me and will be enormously grateful. Sorry for my poor english.
It sounds to me that you had lost root.

Hmmm... It says you still have root (the prompt changed after "su")
I personally don't use ADB much. I have Root Explorer (grabbed it legally for free from Amazon ages ago) and Wifi Explorer Pro (same method) so I basically WiFi myself the files I need sideloaded then move them around on the device itself. But if you've lost launcher, you have deeper issues.
Have you tried ADB push any launcher? Or even a download store like 1Mobile or Aptoide?
ADB is basically a Linux shell debug into Android, so you need to learn some Unix shell commands. I'm sure you can find ADB guides with the basic commands, like "ls", "cp", and so on.
You need to check the directory and see if the system/app and other system directories are still there. This is one reason I only play with the copy of ROM I have (see Safestrap Recovery).
can someone explain how to use bypasslkm in further detail. i looked through multiple threads but im stilll not getting the handle on it,
Open your terminal emulator on your phone (download one from Google play if you don't have one) open the terminal and type the following commands (Pressing enter to execute each one)
su (sands for switch user, used alone will switch you to the "root" user. Equilivent to Admin in windows)
cd /data/local/temp (cd - change directory, followed by the complete folder path you want to navigate to)
chmod 755 bypasslkm (not going to get too in depth with this one because I could go on for a while with it but "chmod 755" changes the permissions to read, write, execute for the root user and read/execute for everyone else)
. /bypasslkm (. / tells the system to look in the current directory and, in this case, execute bypasslkm)
Hope this helps clear some things up for you!

Thats not an error. If you had bypasslkm anywhere on your phone, it should now be in /data/local/tmp with the right permissions and should have executed. Make sure you downloaded the bypasslkm binary linked above

The permissions should be 755, as Surge said.
If you KNOW it's in /data/local/tmp, then do this in a terminal emulator window:
Code:
su
mount -o remount,rw /system
chmod 755 /data/local/tmp/bypasslkm
/data/local/tmp/bypasslkm
insmod /system/lib/modules/dhd.ko
mount -o remount,ro /system
exit
If this doesn't work, DO NOT post just "it didn't work". Say what you did, why you think it failed. Capture the output and reply here with it.

I figured it out! Here is exactly what I did:
after downloading the bypasslkm.bin from the dropbox link, I used ES File Explorer (WITH ROOT ENABLED) to move the bypasslkm file to directly to the data/local/tmp location. NOTE: there are a few places marked "data" and "local" on the phone, so when you open a "data" folder, make sure you find the path in the right order [ i.e. first data, then local, and then tmp]
Using a ROOT FILE EXPLORER app (because ES doesn't have what you will need) go to the bypasslkm file, long press, and select permissions. It will display with permissions are currently set. At the bottom, it SHOULD display the total sum of the permissions selected. Basically, that means by selecting the right boxes, you can change the permissions to 755 !
7 5 5
user group world
r+w+x r+x r+x
4+2+1 4+0+1 4+0+1 = 755
These setting will give you the 755 that you need to pull this off .
When you have the permissions changed to 755, the last step was actually very easy. But if you want to play it safe, then I will tell you the root file browser I specifically used to do the last step.
I used the app Root Browser version 2.2.3 ( i literally googled for any generic root file explorer and this came up )
ok, so when you have the permissions changed, long press on the bypasslkm file.
select "Open With" and then select the option "Open As.."
At the bottom of the options is "script file" select it.
after doing so, select the option "Execute" and... Voila! I immediately regained my WIFI !!!!! \>w</
I hope this guide helped everyone out. I tried to be as specific as possible.

after downloading the bypasslkm.bin from the dropbox link, I used ES File Explorer (WITH ROOT ENABLED) to move the bypasslkm file to directly to the data/local/tmp location. NOTE: there are a few places marked "data" and "local" on the phone, so when you open a "data" folder, make sure you find the path in the right order [ i.e. first data, then local, and then tmp]
Using a ROOT FILE EXPLORER app (because ES doesn't have what you will need) go to the bypasslkm file, long press, and select permissions. It will display with permissions are currently set. At the bottom, it SHOULD display the total sum of the permissions selected. Basically, that means by selecting the right boxes, you can change the permissions to 755 !
7 5 5
user group world
r+w+x r+x r+x
4+2+1 4+0+1 4+0+1 = 755
These setting will give you the 755 that you need to pull this off .
When you have the permissions changed to 755, the last step was actually very easy. But if you want to play it safe, then I will tell you the root file browser I specifically used to do the last step.
I used the app Root Browser version 2.2.3 ( i literally googled for any generic root file explorer and this came up )
ok, so when you have the permissions changed, long press on the bypasslkm file.
select "Open With" and then select the option "Open As.."
At the bottom of the options is "script file" select it.
after doing so, select the option "Execute" and... Voila! I immediately regained my WIFI !!!!! \>w</
I hope this guide helped everyone out. I tried to be as specific as possible.

Thanks for the support. Glad I could help. Has your WIFI remained on, though? The solution I posted works, but only for a short amount of time. rebooting the system undoes the work I did and I have to go back into the root browser and execute the file all over again to get wifi.
Can Surge or someone else offer any expertise?
with the permissions changed properly, I tried executing the code, and still not working.
I have safestrap enabled, and I have sound restored. I am currently on android 4.3 from the downgrade provided by Surge. Its rooted.
If I were to upgrade to the rooted version of NC5, would that help fix the wifi issue, or would it carry over?
Any input going forward is appreciated!

It is possible to automate this.
Create a file with the following contents:
Code:
#!/system/bin/sh
/data/local/tmp/bypasslkm
insmod /system/lib/modules/dhd.ko
exit
Save this file as /system/etc/install-recovery-2.sh.
Make sure that the bypasslkm file is in /data/local/tmp.
Reboot, and you should now have WiFi again.
[Note: this assumes SuperSU has it's custom copy of /system/etc/install-recovery.sh in place. If that's not there, it's still possible to edit /init.rc to add a stanza to run this command.]

I do NOT have supersu's install recovery 2 file in the location you said. I only have the regular install recovery file.
What I should I do? Could I create the file in laptops termial?
The first line of code gave me the error "file not found"

I tried again.
Ok, so I figured out the coding a little bit. Im not used to this, so forgive my ignorance.
I did the code as u typed it. BUT I made a change. Because I kept getting the "file not found " error. I added ".bin" to the end of the bypasslkm code line. It generated a real response. I felt relieved. I went ahead and typed the last line of code.
THEN I was told the file already exists... I have attached a picture of what I got in android Terminal

You should have /system/etc/install-recovery.sh
It will run /system/etc/install-recovery-2.sh if it exists. What I would do is to create the file on your PC, put it onto your SDcard on the PC, then use Root Explorer to put it into place.
The "file exists" error is because you already have the WiFi module installed. That won't happen when this script runs at boot.

Ok. I'll try that tonight.
But I have a few questions
Im basically trying to autostart the wifi module when the phone boots up right? Are there any apps that can accomplish this specific task?
Also about the downgrade in general. Did anyone get their SD card permissions restored after downgrading? I donwgraded to 4.3, rooted the phone, and somehow I STILL cant move apps to the sd card! Im beginning to suspect that thr issue may be with the card itself, which can be fixed with formatting the sd card. But has anyone had any problems with moving apps to the sd card?
Finally, the bug question concerning the wifi issue.
Is this probkem specific only to those with the downgrade? If so, should upgrading to Surge's rooted kitkat (with sd card permissions and tethered enabled) resolve the wifi issue?
I also noticed that I had wifi access when the phone had no sound. Only when I flashed the Non-HLOS bin file did I encounter this wifi issue.
Thanks for the feedback so far, I just need to understand whrre to go from here

I'm sure there are programs that can be set up to run scripts as root during boot; However, that's complicated since you want this to run while the phone is booting, before there's any opportunity to allow SuperSU to ask for permission.

That's a problem that's fixed by an edit to /system/etc/permissions/platform.xml, adding a stanza that permits external storage write access.

The need to run the "bypasslkm" program is because of the downgrade. If you go to a clean rooted Kit Kat ROM, it shouldn't have any issues with WiFi being enabled. That may be the easiest way to fix this.
Hi all.
I apologize ahead of time that this thread is so long, but I have quite a problem. I am in the process of rooting my unlocked Galaxy S4 running Android 5.0.1 lolipop, but I cannot add the su and busybox to my /system/bin folder because /system is a read-only filesystem. I have done just about everything I can think of to mount and remount, like typing adb remount and mount -o remount,rw /system, but they just give me the same answer saying permission is denied. I tried doing adb root to get the permission I needed, but I got an error message saying that adbd cannot run as root in production builds. After doing some research, I found out that the /default.prop has debuggable=0 and that may be what is not allowing me to restart adb as root. So I opened the shell and typed cat to see and sure enough it was set to 0. So I did echo and set the variable to 1. However, whenever I hit enter, I got another error telling me the same thing, that /default.prop is a read-only file. I am at a loss of what to do now. How I can mount and unmount the /system if I can't get any permission to do so? Any help would be greatly appreciated. I do ask though, please don't recommend ready made apps that can insta-root your phone like a supah-hackah because I want to do this the hard way for gratification's sake. I am just stuck and need some help to get the /system to allow writing as opposed to read-only. Thanks in advance.
