Messed up my superuser whitelist, help

Hi, I am on Darchdroid 2.7 and while I was trying to push Camera.apk to my phone I kept getting the "read only file system" message. I did not know at the time that the first thing I should've done was "adb shell" followed by "su" to make sure adb got onto the superuser whitelist.
Well, i proceeded to read around the net (here)and I used this command I saw around to get root:
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
cd /system/bin
cat sh > su
chmod 4775 su
Click to expand...
Click to collapse
And it worked, I was able to push the Camera.apk.
Now i have a problem though, when I use an app that requires root, it no longer brings up the superuser whitelist app even if I've chosen to forget them from the whitelist.
Titanium backup gives the following message:
Warning -
BusyBox works but the "su" command does not elevate to root: "whoami" reports "app_47" instead of root/uid 0. I think your "Superuser Whitelist" system app does not work. Please check with your ROM provider.
Click to expand...
Click to collapse
I searched around the net and I actually found a post regarding this from the dev behind Titanium Backup saying that if this message shows up, it means that the app is not properly communicating with the superuser whitelist....
Now, I believe that the commands I put in adb previously did away with the superuser whitelist and just gave root to whatever app asks for it, I don't know if I am correct.
Can anyone verify this? If so, is there a way to undo what I did? ..or will reflashing Darchdroid be my best option?
I really dont want to flash, I just got this rom settled in :\
Thanks in advance!

Chainfire 3D help [CM7-SD]

I'm running on an SD version of CM7 N115.
Used Verygreen's size agnostic to get it loaded on there.
The problem is, I can not install chainfire drivers because /system is not writeable(RW). I was able to install this previously on a dual-boot SD card with phiremod on it.
What I've tried
ES file explorer change permissions- Result: Denied
ES file explorer root options- mount system as writeable option- Result "failed to mount"
Was gonna try the ADB method but my device isn't even recognized when I start it up.
Anyone think they could lead me in the right direction?

I figured it out. Anyone else having trouble mounting partitions or making /system rw to install these drivers this is what I did.
1. Open up terminal emulator on your nook
2. type su and enter. type "bash" without the quotes.
3. then type mount -o remount,rw -t yaffs2 /dev/block/mtdblk3 /system
I was able to install the drivers after this.

Or you can install the latest Busybox using the Busybox Installer app with the blue arrow on the icon. The other one with the gears in the icon doesn't work for me.

You will have to provide more information. Like if your running off SD, what version of CM7 your running...etc.

BusyBox problem: installed twice, removed one, damaged system

Hello guys, please help me out with this problem! I've been working on all day but my phone is still bad...
When I rooted my device BusyBox was supposedly installed by the toolkit I used to root (mskip's).
Then I installed BusyBox installer market app (Stericson's) and it said "BusyBox location could not be found". I thought it wasn't installed so I used the "smart install" with the default values, so it was installed to /system/bin and all the applets were listed as symlinked to /system/bin/busybox
After a while I realized that it was installed both in /system/xbin (by the root toolkit) and in /system/bin (by busybox installer). I used the uninstall option from the busybox installer app to remove it from /system/bin again and leave just one installation to avoid conflicts. This was not a good idea it seems. After uninstalling and rebooting, the phone started to work incorrectly, wifi doesn't work.. and most importantly, USB connection is dead with Android fully booted. the battery charges but the PC doesn't detect it. (It works on Recovery mode though).
I have an idea of what may be wrong. I think the "BusyBox installer" changed all the symlinks to system/bin/busybox, so when it was uninstalled, the phone was left without any of the applets of busybox even though the file /system/xbin/busybox is still present.
Or maybe I'm not really rooted anymore? However, the su binary is still present in /system/xbin/su but I still can't get to work commands like "mount".
How can I fix this problem? I will greatly appreciate any suggestions.
I think it might be fixed by installing busybox to /system/bin or even just copying the /system/xbin/busybox file to /system/xbin/busybox but because the phone is not working correctly I haven't been able to do that...
Here's the information I've gathered so far for you guys to PLEASE help me out with this:
SuperSU is installed and seems to works fine.
"BusyBox Free" installer app doesn't work. If I open it, it shows only black with the three buttons in the bottom but they can't be "clicked. It has been granted root permissions.
"ES File Explorer" gets root permissions but is unable to mount /system as writable (to copy the file).
In a terminal emulator application (Jack Palevich's), this is what I get:
Code:
$ which busybox
/system/xbin/busybox
$ ls
ls: not found
$ busybox ls
(works, outputs the directory content correctly)
$ mount -o remount,rw /system
mount: not found
$ busybox mount -o remount,rw /system
mount: permission denied (are you root?)
$ su
(the terminal emulator app has root permission, but when issuing "su" command, the cursor stays inactive for several minutes and when it finally responds, the following operations are still not succesful. The "su" doesn't seem to work.
$ busybox mount -o remount,rw /system
mount: permission denied (are you root?)
$ /system/bin/busybox --install -s /system/bin
busybox: /system/bin/zcat: Read-only file system
busybox: /system/bin/mountpoint: Read-only file system
busybox: /system/bin/nohup: Read-only file system
My plan is to make the USB work so I can use the toolkit again to restore a stock firmware and clean this mess. Oh, I have stock recovery and stock boot image if that's of any help to know it.
How can I issue the commands I need? or fix this problem?
I have basic linux experience so if you need the output of any command please let me know.
Any help is appreciated. Thank you!

... i think that flashing cwm recovery(.tar.md5) with odin and flashing a root+busybox.zip with cwm recovery should be the fastes way to fix this .... only thing is that it erease your "costum binary count" but with the "Triangel Away" app you can reset that counter ...

Thank you for the hint, enox. I'm will try to install the custom recovery now.

Thanks again enox for pointing me in the right direction. The phone is working again. I'm sharing what I did in case it helps someone in the future:
1) Installed the custom recovery 'twrp', provided by the toolkit (program_folder/recovery/recovery-twrp-2.4.3.0-GTI8190.tar) using odin with the phone in download mode.
2) Flashed this busybox uninstaller using twrp recovery. The phone wasn't working fine yet, so I continued to the following step.
3) Flashed a root+busybox.zip provided by the toolkit (program_folder/root/SuperSU-1.25-Busybox-RenameRecoveryRestore.zip) using twrp recovery.
At this point, the phone was working fine but to be sure that all symlinks were correct, I ran an additional cleaning script which you can find at the end of this post, along with my comments talking to myself while I was troubleshooting the problem.
I'll go to sleep now. Thank you.

Got a PM and I thought it would be better if I reply to it in the forum so others can benefit as well:

[SOLVED][Q] 4.4.3 after restart restores previous values

Hi!
I have problem with my HTC One m7 (ViperOne 7.0.1).
While I changed something in /system/app folder (eg. deleted a "DriveActivator.apk" - successfully accomplished) and restart phone, I see again that deleted app!!!
Do you know why? I'm using RootExplorer, I have root and granted permissions to r/w.
It seems like system restores some kind of backup - I don't know why, and I don't know how to fix it (I mean do some permanent changes in /system/app).

It appears that the System isn't booted with RW capabilities
There's a nice long command that I'll give you later that will fix it
If you wanna get it sooner and aren't afraid of adb shell (make sure you have root access enabled for adb AND apps, not just apps) you can Google remount Linux system read/write and you should find it
You'll need to modify that command to reflect the One, but the name of the partition should be something like by-name-system or something
I'll get it later if you need it when I wake up

Stupid question - how I can check whether I have root access enabled for adb and apps? I have superuser app, and in settings I can see: "Superuser Access: Apps and ADB" - is this what you are wrote about?

That's exactly what I'm referring to (The settings thing)
Lemme go find that command for you
---------- Post added at 06:00 AM ---------- Previous post was at 05:56 AM ----------
Wish I knew this existed when I was working on the L port
There's an app to do exactly what you need without looking up partitions
https://play.google.com/store/apps/details?id=com.beansoft.mount_system
Although if you want to go through terminal, here's a tutorial
http://ckirbach.wordpress.com/2012/11/27/how-to-remount-system-as-read-write-in-android/
Basically, you use grep to find the name of the system partition, then run the mount command to remount the partition you found in that precious step

I have this app: Mount /system (rw / ro), also I have this option in superuser and it works fine - I mean that I can change /system/app or for eg. edit /etc/hosts (I get message that ES explorer granted superuser access), but after restart I see previous files (before changes)... I have no idea how make this work - maybe I need custom kernel or something? I want to make permanent changes in system files...
I have reinstalled system (clean option with wipe all data), but still no results...

I have tried - still no results. My system already has RW permissions. Problem is that after restart my files are "restored".
Analogously like in Cisco IOS - commit but without write memory.
Maybe I should go to recovery and do something (but I don't know what)?

This should remove DriveActivator (while script is ongoing I see no errors), but after reboot DriveActivator.apk is still in /system/app...
Is there any other way to permanently remove/change files in /system/app?

Make life simple: erase the apk while in custom recovery, TWRP has a file manager, or you can use Aroma File Manager
even adb commands while booted in custom recovery are better than booted up ROM.

I would recommend using the Aroma File Manager instead of TWRP's, just place all the files you'll need on your internal storage (including Aroma File Manager), then reboot to select "Install" to run the Aroma File Manager and remove/replace whatever you need to.
You may need to also check if the permissions are right, I can't remember if Aroma File Manager has that built in.
remember that once you are in recovery to mount /system (in the Mount menu)
and you can even use adb shell, and adb push commands to replace the .apk.... i'm just guessing it's easier with a GUI interface.

Well for one thing if you disabled/uninstall Unified Search, it allows google search to work correctly in the launcher, also without root you can replace the amazon keyboard with the google keyboard and get voice search.
Edit: We need to probably install Google play services properly to get Google Play Games to work correctly but I am not sure.

The ability to install apps depending on root is awesome.
If you are asking for wishes, then I wish I could use CyanogenMod on this device.

I have de-amazonified my tablet a bit. Cant wait to get a custom rom installed on it though.

we need a safe list with what apps can we delete... i did the same but i don't know for sure what to delete and what to keep... i mention that i don't use amazon apps nor i logged in..

You can use titanium backup, and remove it like that. I would make a backup firs though just in-case.
Also, I need help trying to unhide the firelauncher process. I have the command here "adb shell pm unhide [package:com.amazon.firelauncher]"
But I need the other command first so ADB can talk to my tablet. Because I ran the command, and it just says "true" when it should say "false".

If you are already rooted you don't need to do all that stuff.
Just adb shell
su
mount -o remount,rw /system
rm -r /system/priv-app/com.amazon.firelauncher or whatever the package is called.
Reboot and it's done.
Remember to install a launcher before this.

Will this work if I hid the process with ADB before hand? If not, how do I unhide it? What command would I use before "adb shell pm unhide [package:com.amazon.firelauncher]"

Don't know, try if it works hiding, but I doubt it.

I want to replace the hosts file with the one of my Lenovo S660 (China phone). The S660 hosts file is about a mile long and has entries like "0.0.0.0 bad.ad.server" - a very basic but effective way to avoid a lot ads, even at apps. I have not yet took a closer look but I think I would create a mix of both files for the fire.
So, what are the steps?
I have done similar things to my rooted Sony Experia Tipo concerning modifying files at /system, which is mounted RO as default. So I remounted it RW with ES-Explorer, modified what I had to and mounted RO with ES-Explorer again.
I wonder, if this is ok, because of the security means the fire/android has.

I took a chance and I was successfull.
I attached the unchanged hosts file from my Lenovo S660 /system/etc/ as hosts.lenovo.zip file. The fire hosts has just 1 line: 127.0.0.1 localhost. The lenovo's hosts has 25858 lines.
Code:
- unzip hosts.lenovo.zip -> you get host.lenovo
- rename hosts.lenovo to hosts
- connect fire
- adb push hosts /data
- adb shell
- $ su -
- # cd /data
- # chmod 644 hosts
- # exit
- $ exit
- ES Explorer
- Enable root explorer
- remount /system rw
- go to /data
- mark hosts
- cut hosts (to memory)
- go to /system/etc
- mark hosts
- rename hosts to hosts.old
- insert hosts from memory
- remount /system ro
- exit ES Explorer
done.
should work, use at own risk.
Note: You cannot chmod 644 at /mnt/sdcard1 because it is vfat there, that's why you use /data.
Note: You cannot write to /system/etc while at adb shell, even if it is mounted RW, that's why you have to use ES Explorer which will ask you to choose the path with android overlay window - which makes it work (at least my experience).
If you have apps which showed ads before, then you might keep on seeing the very last forever. Or a broken link sign. Or even a popop with broken link sign. Or your ads hosts is missing at the lenovo hosts file and you keep on seeing ads. There even my be websites you cannot visit anymore - which I have not yet experienced, but the risk exists, or will come.
If interested, take a look at http://winhelp2002.mvps.org/hosts.htm for more information and use for your windows or linux pc.
If you don't like it you can go back, you have a copy of your old hosts file.

Check out the adaway app (open source). It blocks ads through the host file just like you're doing except it puts the host file in place for you, combines host files from a couple different sources (running de-duplication on them) & auto updates your host file as new ad severs are added or removed. Absolutely beats rolling your own host file manually.

That is new information to me, thanks.
