Error during root attempt —*Mount: Operation not permitted - G2 Q&A, Help & Troubleshooting

Hey Everyone,
I'm attempting to root my VS980 (software version: VS98011A) on OS X via Terminal.
I am able to the following successfully:
View my device with the command ./adb devices
Push required files supplied by TheCubed's post
I cannot successfully execute the command below. It returns the error "mount: operation not permitted"
Code:
./adb shell "mount -o remount,rw /system
Am I missing a step that is causing an error? Do I need to use Loki Bootloader bypass first?

Occupying space for updates and hopeful solution for other mac users.
UPDATES:
Some more tinkering shows that SU cannot be found in /system/bin/sh —*Am I safe to push su to this location? Will this aid in achieving root?

- Get visionary+
- Temproot your legend with it
- Use commandline with adb on your pc to flash misc1-2.img.
type the following commands from the folder where you have adb;
Code:
adb shell
su
accept the notification on your phone if one comes up
and then in the command line type this;
Code:
/data/local/flash_image misc /data/local/misc1-2.img
That should be enough to make it possible to run the 1.31 RUU.
same problem here..try many way as stated!!

and then?
run the RUU_Legend_HTC_WWE_1.31.405.5_R_Radio_47.26.35.04_ 7.05.35.26L_release_126592_signed.exe?

Did you get the # symbol after the su command? If not, then you have to do temp root again.
What does ADB say? Do you have Debug Mode eneabled?

[Q] Rooting Problem, Won't mount. Line needs correction.

Hi, I am currently trying to room my Blade but I get this problem in cmd
$ exit
exit
C:\android-sdk-windows\platform-tools>adb kill-server
* server not running *
C:\android-sdk-windows\platform-tools>adb start-server
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
C:\android-sdk-windows\platform-tools>adb shell
# mount -o rw,remount /system
mount -o rw,remount /system
Usage: mount [-r] [-w] [-o options] [-t type] device directory
# exit
exit
C:\android-sdk-windows\platform-tools>adb push su /system/xbin/
failed to copy 'su' to '/system/xbin/': Is a directory
Click to expand...
Click to collapse
As you can see, I am unable to copy over su to system/xbin.
Does it have to do with the mount command line?
you dont need to use the mount command at all, you can just type 'adb remount' instead of 'adb shell', or if you want to use the mount command then the correct line is this:
mount -o remount,rw /dev/block/mtdblock5 /system
you were missing the device part of the mount command line, it's /dev/block/mtdblock5 for /system on the blade.
you've just given me an idea to post a rooting guide, there is an easier & better way, using adb, fastboot, clockworkmod & superuser.
I fixed it by just getting z4root and rom manager for clockworkmod.

Cool. I've written a rough rooting guide using adb & fastboot here: http://forum.xda-developers.com/showthread.php?t=1319257
z4root uses a root exploit that only works on older versions of android. Some versions of the blade sold in some countries use newer versions of Android (2.2.2 or 2.3.5) that have that vulnerability fixed. I wrote a guide that will work on any blade, because it doesn't use any root exploits - it's bad that z4root worked, you need to update your rom!
The blade has an unlocked bootloader, so you can install clockworkmod using 3 commands
Code:
adb reboot bootloader
fastboot flash recovery recovery-clockwork-5.0.2.0-blade.img
fastboot reboot
Then use clockworkmod to install the superuser zip file, or custom rom.

Failed to copy to /data using adb push

Hi,
I am trying to push
Code:
$ adb push androidvncserver /data/androidvncserver
failed to copy 'androidvncserver' to '/data/androidvncserver': Permission denied
When I do 'su' in 'adb shell', i get a root prompt , that means I have rooted my device, right?
Code:
$ adb shell
$ su
#
If so, how can I push to /data?
Thank you.
Your default shell is secured - means, when you're executing ADB command without executing something through SU, you're going through the regular permissions.
To enable insecure boot, set ro.secure to 0 in your build.prop. I'm not sure if it's enough, though, or if you need a kernel compiled with security off to take full advantage of insecure adb commands.
You can push the file to sdcard, enter shell, enter su, and in root shell copy the file where you want it to be.
And you're posting in the wrong section. There is Q&A for questions, please move there.

[TRICK]Installing Google Dialer after towelroot

I spent a few minutes struggling to install Google Dialer after rooting my latest OTA note 3 with towelroot. Here's what I discovered worked (works for putting anything in the system folder):
Step 1: Install ADB on your computer, push tr.apk (towelroot) and install. Run towelroot, install busybox
Step 2: Open up two command prompts on your computer. In one, ADB shell and su. I will refer to this as "the su terminal" for now. Ignore the second for a bit.
Step 3: type "mount | grep system" and extract the first bit:
Code:
/dev/block/platform/msm_sdcc.1/by-name/system /system ext4 ro,seclabel,relatime,
data=ordered 0 0
The important part is the first section, /dev/block/platform/msm_sdcc.1/by-name/system. Also notice that it is mounted as RO, read only.
Step 4: type the following, replacing the /dev/... line with your own from above (maybe the same, idk)
Code:
# mount -o rw,remount /dev/block/platform/msm_sdcc.1/by-name/system
Step 5: Confirm it worked by running mount | grep system again:
Code:
/dev/block/platform/msm_sdcc.1/by-name/system /system ext4 rw,seclabel,relatime,
data=ordered 0 0
Note that it is now RW.
Now we run into an issue, if you go to your second terminal and try to use ADB to push to system it still says read only. If you go to adb and try to adb root it says disabled for production builds. If you go into an app such as ES file manager, it still says read only. I also tried pushing the file to the sd card and using MV to move it while in a su shell, but that didn't work either (error about cross device something or other)
However... I found a workaround.
Step 6: On the second terminal, use adb to push your file to somewhere on your sd card, in my case, /storage/emulated/legacy/ worked.
Step 7: on the second terminal, adb shell and su.
Step 8: On the first terminal cd /system/priv-app/ (or any folder where you need to write something)
Step 8.?: On the second terminal cd /storage/emulated/legacy/
Step 9: Run the following commands
First terminal:
Code:
nc -l -p 1234 > com.google.android.dialer-1.1.apk
Second Terminal:
Code:
nc localhost 1234 < com.google.android.dialer-1.1.apk
Finally, on the first terminal, chmod 777 com.google.android.dialer-1.1.apk, and install by tapping within ES file manager or similar, then adb reboot.
You will need to use a tool to create a shortcut for the application, it does not get one this way.
You now have the google dialer installed on your Verizon Note 3, rooted with TowelRoot.
Trick can be used to push to the system folder without adb root or adb remount working.
Enjoy!

Rooting LG V20 H990DS?

Been reading this guide here --» https://forum.xda-developers.com/v20/development/dirtysanta-h990-t3624296
despite much of a mess that it is and poorly written in some regards. I can make perfectly good sense of it all, but the commands issued most of them are pretty useless, or don't work as they're instructed to do.
Let me point out some stuff here, cuz I'm trying to work my way through the tutorial to root my LG V20 H990DS (International) btw;
ok so the first part here it explains the following;
6. Using dirtysanta's steps: Run "RUNMEFIRST.bat" <-- Do not close.
7. Run "step1.bat" <-- Wait until you can type something again.
Click to expand...
Click to collapse
in my case here I'm using Linux, not Windows to do this, so things are simpler, the RUNMEFIRST.sh executable literally does nothing, when I can see it clearly is suppose to do something, let's take a look at what that files trying to run;
Code:
#!/bin/sh
# runmefirst.sh
#
#
# Created by me2151 on 12/13/16.
#
adb logcat | grep -a dirtysanta
OK, so it's using logcat to see what the phone is doing while piping to grep to watch out for dirtysanta being written to the phone while you have step1.sh running in another terminal instance, when that command completes you're left in ADB Shell of your device. Meanwhile the first shell script doesn't report anything going on, OK that's fine, doesn't matter since it wrote the contents of the required files to the phone, so it's there, as it should and as it's described in the shell script;
Code:
#!/bin/sh
# Step1.sh
#
#
# Created by me2151 on 12/11/16.
#
adb push dirtysanta /storage/emulated/0
adb push aboot.img /storage/emulated/0
adb push dirtycow /data/local/tmp
adb push my-run-as /data/local/tmp
adb shell chmod 0777 /data/local/tmp/*
adb shell /data/local/tmp/dirtycow /system/bin/run-as /data/local/tmp/my-run-as
adb shell /data/local/tmp/dirtycow /system/bin/applypatch /data/local/tmp/dirtycow
adb shell
Now this next part, doesn't work at all, because in the tutorial guide, they said to do chmod 777 permissions on "/storage/emulated/0/*" this doesn't work because operation is not permitted by the file owner and group root, there is no write permission to change permissions of that directory structure.
Code:
chmod: chmod '/storage/emulated/0/Android' to 40777: Operation not permitted
and yes /storage/emulated/0/ is suppose to be your storage userspace of where you save your files and stuff. Your "virtualized" SD Card space, you have normal read-write access there anyways. The next part of that tutorial says to check the id output from the Terminal Emulator app on Android, and check for the response "untrusted_app", that I do get, if you're doing it through ADB Shell you'll get "context=u:r:shell:s0" instead.
Part 12 of the tutorial has misuse or incorrect command line usage for applypatch, it will not simply execute because the command line usage is incorrect like so;
Code:
applypatch /system/bin/atd /storage/emulated/0/dirtysanta
it'll just simply return the following;
Code:
usage: applypatch [-b <bonus-file>] <src-file> <tgt-file> <tgt-sha1> <tgt-size> [<src-sha1>:<patch> ...]
or applypatch -c <file> [<sha1> ...]
or applypatch -s <bytes>
or applypatch -l
Filenames may be of the form
MTD:<partition>:<len_1>:<sha1_1>:<len_2>:<sha1_2>:...
to specify reading from or writing to an MTD partition.
obviously the step2 shell script can't do anything because there is nothing to backup, since it's calling to backup the boot images off the device.
So far I haven't been able to find any comprehensive or updated rooting guide for LG V20 H990DS in particular, nothing new worked on seems to popup anywhere as of yet.
bump this
No help for this at all? Just gonna be another one of those dead-end topics with no answers?
