N00b Filesystem Question

Don't laugh - I know the answer will be obvious.
Can anyone tell me why, when I start a terminal, then SU and enter
cd /sdcard/
ls
I get to see everytning I expect on the SD card.
BUT
If I boot to the Recovery ROM, access the phone with ADB and do
adb shell cd /sdcard/
adb shell ls
I don't see any files at all?
Some kind of virtual filesystem going on in there?
Just curious.
TIA

You should still be able to access adb shell at the shell level, what is likely happening is that you are dropping into a root shell and this is causing SuperSU to prompt if you want to allow adb shell to have root access. What are the exact steps you are taking when you go to use adb shell?

I Use Android Screencast Plus Android SDK, Then I Use Command Prompt
.Adb Shell
.Su
At That Point Super Su Is Prompted

I would recommend try starting adb shell (adb shell command) and not dropping into a root shell then skip the su command. So just do
Code:
adb shell
To start adb shell, and then skip the su command.

If I Skip su The cmd Says Not Permited
Code:
•adb shell
•su
•chmod 777 /data/dalvik-cache
•cd /data/dalvik-cache
•chmod 777 ./
This Is My Attempt, Is There An Alternative

Trying using adb shell from the command line, instead of Android Screencast. Also what are you trying to do with the device extract your personnel information?
Any progress with this? I'm in the same situation

[Q] Couldn't open ADB Shell

In recovery mode, I couldn't access shell window by using adb shell command. (Referring to the attached pic)
The device has already be rooted and OS run very well.
I also checked the hierarchy of the system, system/bin/sh does exist.
So what's wrong with it, any advice welcome!
BTW, this adb file works fine with my another mobile featured with Qualcomm CPU, hence is adb file dependent on type of CPU?

Stuck in settings

I was trying to install gapps and now when I reboot I am stuck and the Play Store language select screen. When I click next, it takes me to settings. I have no home or back button so I cant get anywhere other than the settings menu. I have tried a factory reset with no avail. I also tried a manual update, but I have disable OTA updates so it wont recognize the .bin file on my SD. If only I could get to ES File Explorer. Any tips on fixing this problem?
Code:
adb shell "su -c 'mount -o rw,remount /system'"
adb shell "su -c 'mv /system/priv-app/SetupWizard.apk /system/priv-app/SetupWizard.apk.old'"
adb shell "su -c 'mount -o ro,remount /system'"

Care to elaborate? I am a complete noob and shouldn't have been trying this at all. I can't access anything on my Kindle other than settings. Do I run this in command prompt on windows?
Edit: I also wanted to add that I am not one of the guys who sits around waiting for an answer without researching the problem lol
You need install adb on your PC - http://forum.xda-developers.com/showthread.php?t=2317790
Install drivers for our tablet (no need to reboot fastboot just manual install drivers for your kindle at device manager) - http://forum.xda-developers.com/showpost.php?p=59268023&postcount=8
Open CMD (cd C:\Program Files (x86)\Minimal ADB and Fastboot>)and paste these commands. I assume you rooted if you can block ota.

Apparently I no longer have root since I reset to factory. I do have the adb drivers installed, but I get stuck when using the command prompt because I dont have su access. Anyway for me to root it with only access to settings? I am on 4.5.2
are you sure?
earlier I had root even after hard reset on 4.5.2
anyway you could try install kingroot but I do not sure
I think @Cl4ncy and @Davey126 may clarify this.

Yes, I no longer had root access. Thanks to all of your other help and suggestions, I have been able to successfully get my Fire HDX working again. With all of the info you gave I was able to research and piece together what I needed. I was able to install Kingroot through cmd and then use the commands you gave to get rid out of settings. Thanks alot!
