[Q] LagFix (fstrim) on Prime - Asus Eee Pad Transformer Prime

Hi,
I have downloaded LagFix (fstrim) for my TF201 and when I try to use it it says that it does not have root permission. I am rooted and I have root permissions, since I have Titanium Backup already running on my Prime. So its probably LagFix (fstrim) that did not ask SuperSu for permissions, I was wondering is there a way to manually give a permission to an app ? I really want to use this LagFix (fstrim) cause my prime has become sluggish.
Thanks in advance

Go into super su and open up the permission for it and you should be able to change it.

How do you do that since LagFix (fstrim) never asked for any permissions. I know I am a noob.
Sorry it is not SuperSU it is Superuser.
LagFix (fstrim) just never asked for Root permission to Superuser so because of that it wont do the fstrim

I suggest you simply uninstall.. LagFix
then update superuser (I personally love SuperSU)
and then reinstall..
Thanks button deserves a click. no?

Just delete all lagfixes data and open it again

I did what you said its still does not work, I also did what Makrilli said do delete data for lagfixes it stills does not work, it does not get Root permission, I wish there was a way to manually give an app root permission.

You could try to set supersu to automaticly to give access to root. Also you could try to use superuser instead

Unfortunately I did that too, I dont know why it does not want to give root to lagfix when I gave root to other apps just fine in the past they are all still rooted and have permission, including AdAway and Titanium Backup.

Root functions on unrooted p500 with cm7

Is it posible to do root function(overclock, change VM heap, screenshot, reboot etc.) from the cm7 settings, after unrooting the phone?
I think it is possible to do them, but will they work?

It isn't because for that stuff you will need administrator privileges (root) maybe you can unroot but before change your user privileges in a terminal maybe thats a workaround

Root explorer will get rid of SU
You have to delete from 3 places in the system section I just can't remember which 3. I did it on the TF101 and it works
Your dont need root to do it but you may need the paid version of Root Explorer

good luck.
Depending on how you rooted, the superuser app is probably installed to /system. If this is the case then you can only remove it by doing a full root followed by an unroot.

Thanks for the help, but I've since re-rooted via viper mods tool. And actually just unlocked the bl.

I tried using the viperMod and I still couldnt get su permission, what is wrong. It is in the system files and I tried deleting them with the ROOT Explorer app stated above and nothing worked. What am I doing Wrong?
EDIT: sorry I didn't notice that jmikeb92 was not the OP. So this post probably makes no sense.

If I were you I'd root using mempodroid, install the su binary, then use a terminal shell to remove all traces of root (ie: superuser apk, busybox, su).
Another thing you can do is check the permissions on your su binary. Not sure where vipermod puts it, probably in /system/xbin. Check that it is setuid at least. If it is not, that's your problem. In this case gain root using mempodroid and setuid the sucker.

No it is not difficult but you would need some knowledge of linux security. For example what setuid/setgid is, how to change file ownership, how to change file permissions.
There are lots of resources out there if you are interested in that sort of thing.
Hi,
I had this problem and spent hours before I could figure out how to remove Superuser.
Maybe you can try this method:
First, download Root Browser Lite from the market. It's like Root Explorer, but it's free and can work with both rooted and unrooted device. Then, open it and go to system>app. Inside the folder, delete the file 'Superuser.apk'. When it's done, power off to restart the phone.
If that doesn't work, you can do what I did. Search for Superuser in the market and try to uninstall from there. It may take a while. After that if the dead shortcut still appears in the app drawer, you can just reboot the phone and it'll be gone.
For those whose phones are rooted and have Titanium Backup, you can use that to delete the file, too.
Hope it helps.

open drawer, put your finger on the superuser app and hold for a few sec. After drawer goes away, keep on holding it. You will see "App Info" at the top of your screen. Move the superuser there and menu will pop up. Clear cash and disable the app. Now it should be gone.
I hope i helped you
Sorry if i made a mistake. English is my second language.

To root or not to root, that it's the question!!!

Well I've flashed a stock official virgin rom since I'm done with customs, the question its because I have superuser premium and it has the ability to go ghost mode (hide from upgrades so the device won't lose the root) but.... I know the rooting process leave my stock rom untouched being able to receive OTAs updates on my Gnex... but I don't know if the rotting process here will be the same... I mean will I still be able to get my OTAs (aka future ICS updates). On the gtab if I'm rooted?
My tab its carrier free, meaning ill get the OTA as soon as Samsung put the little file in the OTA server... I don't think I'm flashing custom ROMs as i love some Samsung apps wich need the touchwiz framework to work but at least in ICS I got the Nova launcher waiting so i can run Samsung apps with ICS AOSP looks...
Thanks in advance for the info

unrooting is easy. Use busybox app from market to remove busybox, delete superuser app from /system/app with es file explorer or root explorer, download superuser app from market, remove su-binary from /system/xbin or /system/bin. Uninstall superuser app.

[Q] Slim bean 4.2.2 - unroot

Hi,
I really like the slim bean rom.
However, I would like to unroot my phone.
Can I unroot my phone and still keep slim bean?
If yes, how?
Thanks for your help!
in the superuser app settings
Thanks Glebun!
However, it is already set to disabled.
For example my Good for Enterprise app still fails the compliance check.
So I would like to know if I can completely unroot my phone while still keeping Slim Bean.
what superuser app are you using? SuperSU allows for a full unroot
Its built into settings

Exactly.
I can't find a superuser.apk on my phone.
It's not visible in as an app anywhere.
There is no option to uninstall if I open superuser via the settigns - superuser menu..
I've searched the internet to no end and I'm getting more and more confused.
Hope you can help.
get supersu from play then

I did install supersu, but again installing it and then uninstalling it still leaves me with the "# Superuser" setting in the settings menu and it's still rooted.
By the way: I just installed another superuser app (I think it is from the CM mod) and I get a notice saying "Normal, the 'su' file needs to be edited. Choose an installation method. 'Via recovery' is recommended for HTC-devices.
So no succes there.
installing and the uninstalling it will have no effect. read my post - supersu has a setting for a full unroot, use it

root consists of 2 elements
1) The app (or settings) which is a gateway to root if you like, but not actually root itself
2) The SU binary /system/bin/su. This is what actually gives root. The above just allows or denies root access. Using one of the superuser apps, you should be able to unroot, removing this. The settings menu will always remain but means nothing.
You may just be able to use a file manager with root permissions to delete the binary.
that is what I meant

Guys: you're the best!
Turns out that I had to reboot (duh) before the change took effect.
Now I have slimbean 4.2.2 unrooted and can make use of Good for Enterprise.
Thanks a bunch!
A small summary:
1. Install SuperSU.
2. Use the "Full unroot" function of SuperSU.
3. Reboot :laugh:

[GUIDE]Superuser update on custom ROMS

This thread is for users facing difficulties on updating the Superuser app, while running a custom or stock ROM
Most times you might be facing problems like "Singature error". I will give you some instructions on updating Superuser. Here's what you will do:
1. Open Google Play Store and install the "System Apps Installer'' application. It is free and it is compartible with Galaxy Y.
2. Open it and grant superuser permissions to the app.
3. At first, you will see a File Manager. Browse through your sdcard and find the new Superuser app version you have downloaded and you want to install.
4. For example I will install Superuser 3.1.3 . Now find the apk and click it.
5. It will know say "This app already exists. ¿Do you want to overwrite it?
6. Press yes and wait to install.
7. When it's done it will say "¡App installed correctly!
8. Open the new Superuser and update it's binary.
9. You're ready to go.
From now on, if Superuser has ever an update released, you will be able to update it succesfully from the Google Play Store.
Personally tested and working on Evo-x4.2
Get the APKs needed in the attachment below.
P.S. You can use that method too for other apps that you can't update.
And if this won't work on your device, you can try hnkotnis's SGYToolkit [AROMA]

if superuser error.. how to grand system app installer?
superuser Superuser is the app that manages
what apps on your rooted device
have access to su. Apps that are
granted su have elevated
permissions and can modify just
about any part of the system. The
app was originally written by zinx,
and I took it and made it much more
useable. The app consists of two
parts, Superuser.apk and the su
binary.
source http://androidsu.com/superuser/
As mentioned in the OP, it's a guide for force updating Superuser. I didn't mention anything about "error granting su permissions", but I mentioned "error updating su and su binary".
