[Nexus 7 General] shonangreg:
simple mistake: '/sdcard': Is a directory

Again, top posting in this confusing xda-threading UI:

UPDATE: Even though I could not complete this process, I do apparently have root! Google Play has SuperSU listed as an app "Up to date", ditto for Root Checker by joeykrim. And in Root Checker, when I click "Check root", "Verify Root Access", SuperSU does pop up and ask if it should be granted root, I say yes, and Root Checker says I have root.

I did manage to install the SuperSU app once or twice in my recent attempts (also using this rootzwiki guide ). The first time I rebooted, I am sure I did not have root. Maybe the last two times I tried it, I did get root. About tablet says:

Android version

As far as root goes, am I all set? I don't care about using a different ROM or bootloader. I just want to have more control in customizing -- and using Titanium Backup -- and still get the updates when they roll out. Is it all good?

Note: I'm sorry, but I don't understand xda's threading. I've posted three different replies here, two asking for help, and one trying to help someone else, but all three are in one window for me. I also can't find a "view as flat" thread option here. Now I feel like I am cross threading, so please pardon for messy threading, but help me if you can.

I got most of this done, but in the last few steps, after flashing CWM and setting 'mount /system', I had lost adb's access to the N7. So, I went into the options on the N7 and chose "Go back" and then "reboot system now". Now I have no adb connection -- and an N7 in first boot mode showing me the welcome screen.

Did my reflashing "take"? What should I do from here? I was at the end of the "make cwm permanent" and just before flashing SU. Please help.

UPDATE: I tried the "For anybody having trouble trying to use fastboot and come up with a no-permissions error or adb ????????? problem" link to here: http://xdaforums.com/showthread.php?p=32494870#post32494870, but that didn't work either. I added my comment there.

Thanks,

Original message below. Much of this has been worked through. The missing "/" in copying over SU is still an error in FadedLite's original post.

-----------------------------------------------------

EDIT: "adb devices" confirmed I am connected. And the error was that FadedLite's instructions are missing the final slash: The Pre-step should read

/[path]/android-sdk-linux/platform-tools/adb push /[path]/CWM-SuperSU-v0.96.zip /sdcard/

The last slash is missing from the parent post here, FadedLite.

Is the parent article being updated? I'm still worried about other errors being there (like there being no mention of re-locking the bootloader)

Original description of my code and the error:

In the Pre-Steps section, when I type:

/[mypath]/android-sdk-linux/platform-tools/adb push /[mypathagain]/CWM-SuperSU-v0.96.zip /sdcard

I get

failed to copy '/[mypath]/CWM-SuperSU-v0.96.zip' to '/sdcard': Is a directory

What is this saying? It thinks the zip file is a directory? Or that there is no /sdcard to copy to? And if I am just not connected, shouldn't there be a pre-step command to confirm that adb is running and the Nexus 7 is seen?

Also, later one someone mentions the need to lock the bootloader again. Is this not necessary? Or is the parent article not being updated to include the errors spotted?

That is a different kind of unlocking, rommel. What is being unlocked here is the bootloader of the device. What you are referring to is Sim unlocking. That unlocks the system from a particular SIM card, or something like that. I think there might even be a third type of unlocking.

It would be nice if these different "unlocks" were generally referred to with specific names. Buying an "unlocked" phone is ambiguous, though I think that would generally mean "sim-unlocked".

I've got it all, until this:

5. Make CWM Permanent -

1. Boot into recovery

2. Go to Mounts and Storage

3. Mount /System

4. Type in Terminal*

adb shell

When I try 'adb shell" (in the terminal on my PC), I get:

error: insufficient permissions for device

EDIT: 'adb devices" no longer works either. Somehow my connection was cut in one of the ladt on-device operations, it seems. Still i am lost as to what to do from here. Help, please.

I did kill and restart the server, but I still get the same error. I tried this command with "sudo" as well. Same result. What should I do from here?

FadedLite says, "* For some people, it has been reported that you don't have to replace recovery-from-boot.bak. The flash is enough to make the recovery stick." How do we know if this applies to us? It seems getting insufficient permissions to run adb shell would not be the way we would know.
