The "#" sign means you have root.

The "/sdcard #" means you are running a custom rom because the standard rom doesn't place your current working directory in the prompt.

I don't know what environment you have set up currently.

You need to copy su to /system/bin and do the chmod on it, but it seems you are having trouble accessing /system/bin

Please post the output of

cd /

ls -l

cd system

ls -l

cd bin

ls -l

Your /system is not mounted which is why you are having trouble with the instructions. You are running a custom rom when the instructions expect you to be running the stock rom.

You don't need to "root" the phone using rageagainstthecage. Since you have a custom ROM, you already have root as evidence by your "#" prompt.

What you need to do is install the binaries for "su" and "busybox". You can't do that yet because your /system is not mounted. You can't follow the directions here, as is, because you don't have the environment that is expected.

To mount /system in your environment, try this:

mount -o rw -t yaffs2 /dev/block/mtdblock5 /system

cd /system

ls -l

cd bin

ls -l

Please post the output of those commands.

If the second "ls -l" gives you a directory listing then you can continue with the instructions in the first post starting at step (13)

aahhhh i thought when i updated it it took the root off becuase the recovery was blue background thank you

I can't get past step 9. ADB will not connect to the device again even after a kill-server/start-server.


Edit:
followed: http://forum.androidcentral.com/lg-...alling-ota-ls670vc-using-kp500-diag-mode.html

Installed V9, cried, installed VC, and the root commands in the first post worked.

Thanks for this, worked as expected.

Yeah for having root again!

I can't get the Zip file to download. Anyone else having that problem?

My phone came with ZVC installed on it. Will this method work? With the repeated warnings of "if you didn't use the LGMobile update tool to get to ZVC, this will not work" make me nervous to try it...

It's described in big red letters in the beginning of the guide.

 

[generosity]

My point was, I did not accept the OTA update, do I still need to revert to v9? The big red letters do not describe what to do when the phone comes with VC installed already.

Thanks for the assistance.

Yes you need to revert to V9. Full VC (Android + Recovery) is not rootable whether you got it by OTA or it came stock.

Also please note if your unit came with VC, there is a chance it has the new LCD hardware so some steps may not display properly. The phone will still boot/work including the touch screen, just there will be no display feedback.

See RED warning #2 in my signature.

At step 10 when i try to Fire up the shell (again) it says

C:\Program Files\Android\android-sdk\platform-tools>adb shell
error: device not found

You need to revert to V9 first per the RED section of the original post.

I followed the VC rooting process successfully a few weeks ago, and have been enjoying the root privileges. I wanted to adb shell into my phone today, and I got the $ prompt, and running 'su' came back with permission denied. Then an adb reboot got me stuck at the LG screen, but was fixed by popping the battery.

My question is, how do I get the # prompt when running adb shell? And it seems that I can repeat getting stuck at the LG screen. Any ideas as to what is wrong?

Don't know what is up with getting stuck, but to become root in adb shell, turn on the phone, make sure you aren't in the lock screen, type "su" in adb shell, look on the phone for a prompt asking for root privileges, and accept the prompt.

Working on MacBook, can't root

I'm on a MacBook here having some problems with this procedure:

Things go according to plan, step 8 doesn't work, then in step 9 I only notice the phone disconnecting and reconnecting once. I gave it a couple minutes to make sure, but it still only reconnected once so far as I could tell. It kicks me out of shell. I get back in and I'm still stuck in $$$$$. :-\

Any ideas?

rageagainstthecage depends on a race condition. It doesn't always hit gold. You may have to try many attempts before it works. Sometimes sprinkling in an "adb kill-server", rebooting the phone, and rebooting the PC help alter the timings to be more favorable, but again, it is a race condition. You aren't racing Usain Bolt, but more likely the best athlete in your cafeteria. Sometimes you might win, but many times you'll lose.
