[Q] Checking SU access - Thunderbolt Q&A, Help & Troubleshooting

I rooted my phone and I was able to install Superuser and Titanium Backup and both appear to be running successfully. My question is when I run adb shell from my PC and I get the $, I get permission denied when I type SU or whoami? Did I miss something?
C:\>adb shell
$ su
su
Permission denied
$ whoami
whoami
whoami: permission denied
$

just wondering why you need to use superuser when you use adb shell

OK, so why the permission denied response from the OS?

that prob has something to do with it, push that kernel and try again

OK thanks, I will keep that in mind if I run into issues. Everything else is working fine otherwise, so I will well enough alone for now, while I read the docs on the Android Dev site.

[Q] Superuser denied to shell

Hi everyone, I recently installed this ROM here http://forum.xda-developers.com/showthread.php?t=2205516&page=73&nocache=1 (unfortunately I can't post questions on that thread yet). Superuser access works fine from apps and terminal emulator, but if I try to connect from adb with "adb shell su" I get "Permission denied" on my command prompt and a "Superuser denied to shell" toast on the phone.
I can't find a way to change this, apparently the shell user can't su. I tried from the terminal emulator too and here's what happens:
Code:
[email protected]: / $ whoami
u0_a14
[email protected]:/ $ su
[email protected]:/ # whoami
root
[email protected]:/ # su - shell
[email protected]:/ $ whoami
shell
[email protected]:/ $ su
Permission denied

Any help pwetty please?

[Q] adb shell prompt

Hey everyone I got a very technical question
I am trying to set a custom prompt for the shell on an android device running bourne shell (sh), I have suceeded in setting it for a login shell (sh -l) but I would like to make this default for non login like adb or ssh through connectbot @localhost. Normally on linux I could do this by editing /etc/profile but for some reason on my android sh does not read /etc/profile unless it is a login shell. I tried moving the sh binary and replacing the sh binary in /system/bin with a shell script that executes sh -l but I loose superuser access ( shell reports su command not found) so I moved sh back to /system/bin/sh. Does anyone have any Idea which file is read in by sh at launch?

[Q] Should have root, but don't...?

Hi all,
This one is confusing me, feels like I am missing something really stupid...
I am trying to get my brother's phone rooted for him, and he already used some online tools to get halfway there (Unfortunately I don't know what these tools did or how they did it).
So right now if I run "adb root && adb remount && adb shell" I get a full root shell wirh RW access to the /system dir. From here I can copy the su binary into /system/bin and set:
chown 0:0 /system/bin/su
chmod 6755 /system/bin/su
After this I can run su from the adb shell (so the binary does work), but if I try to use terminal on the device itself su claims to have insufficient permissions, and the SuperSU/ BusyBox installers won't play nice for obvious reasons.
What have I missed out on?
Thanks in advance
PS: This is a repost of a question I asked in kinda the wrong place. Sorry about that.

[Q] Chinese Tablet Root Problem

Hi all! I have a Chinese tablet that I need to root in order to run some applications. It mounts a 4.4.2 Android version and I can access via adb by opening an adb root shell. The table is called letine lt707a .
This is what I did:
Code:
adb shell mount -o remount,rw /system
adb push su /system/xbin
adb shell busybox chmod 6755 /system/xbin/su
Then I installed a version of Superuser.apk. When I open a terminal emulator app from the device, if I write "su" I obtain a "Permission denied" message.
Where is the problem? Maybe I have an old binary su?
I also tried with SuperSU without any results.
Thank you for your help!
I have just to push the correct su in the folder, but I don't know where to find it. After that in case of error I must undersand how Superuser communicates with the su. Anyone?
I think the problem is with kit kat. I pushed the su binary that came from superSU, but when I open a terminal emulator to write su I obtain a number zero as output.
If I start superSU I obtain a warning message: the program doesn't find the su binary.
