General :: Why Can't Alter SU Binary To Have System Access Only Instead Of Root

Apr 30, 2014

Imagine a scenario where you have just system access on android , and you want to continually have it, so you use the su binary, with the correct permission and the setuid flag on, and the owner being system, you do:

Code:
chown 1000:1000 su2
chown 06755 su2

you have the ability to change the owner to system as you do when rooting, and you also set the appropriate permission as you do when rooting,

06775 being the permission code to all have execution permission, and the setuid flag on.

But when dealing with system permission that doesn't work. it only works with root.

General :: How To Gain Root Access If Busybox And System App Is Already Installed

Oct 11, 2013

I have a Rockchip RK3188 Tablet with Android 4.2.2, which I need to root ON DEVICE. Actually, the device was already rooted (using a Laptop via the adb bridge), so I already have busybox installed and I have one of my own apps in /system/app. However I managed to delete the su program (yeah great!) and therefore don't have root access any more. I know I can easily root the device again if I connect it to my laptop again, but that is not possible, because the device is at my parent's place and I can't go over there any time soon.

Therefore I want to root the device just with an app. Actually I would only need to copy su to /system/xbin. These are the things I already tried (without success):Framaroot (doesn't work, because framaroot does not support Rockchip tablets)

Writing my own app, which contains su in the assets and using this su for temporary root

Using adb (on the device) for a local connection (adb connect localhost), because if I connect from my PC I automatically have root (doesn't work because Android 4.2.2 has increased security on adb)

Start telnetd via busybox and then execute my commands via nc (doesn't work, because I can't start telnetd in a way that it ends up with a root shell)

My last idea is, that I could maybe gain temporary root access with the app I already have in /system/app. Basically this would be similar to the Master Key Exploit, except that I do not have to fiddle around with the apk and instead install it normally. However I don't know how to continue from that point. I know, I have special permissions if I have an app in /system/app, but which permissions are that? And how can I use those permissions to make /system writeable (and copy my su file there)?

General :: Android Binary To Handle Root Functions?

Oct 6, 2012

Several apps on android market is utilizing some kind of binary and root to call android system methods which normally require permissions only granted to system apps (/system/app).

I am wondering if it is possible to call java methods with C++ binaries using JNI. How the apps are doing this? An example is the launcher Apex launcher, which uses root to allow users to add widgets with the new widgets screen on ICS.

General :: Can Root Android With Own Update Zip File That Installs SU Binary?

Sep 25, 2012

I bought an android 2.3.6 phone which no one has tried to root( it seems). So I was wondering if I could root it by creating an update.zip file containing the su binary and the superuser apk and then installing it in the recovery mode. Will this work? I have failed with gingerbreak, unlockroot and z4root.

Samsung Galaxy S : Recovery Boot Error - Can Not Access To /system/csc/VOD/system

Sep 4, 2010

Phone: UK Galaxy S Issue: Recovery boot error message in red writing

Multicsc : can not access to / system/csc/VOD/system/

Background: I have been trying to root my phone from information found in a youtube video. All went well and the little ninja bloke with the sniper rifle was in the app list. Tried installing busybox and was told that the phone was not rooted´┐Ż..

I think I ran the root application again and at some point I started getting this error message when in recovery. I have since run the one click root method to unroot the phone and the little nija dude is no longer there. Since I rooted the phone it will no longer connect to my wireless network, it finds the network and attempts to obtain an ip address. After a few min it times out and tries again. When I load the phone recovery the error message is still present.

General :: How To Access Android File System

Sep 25, 2013

My objective is to create a text file in an android file system.

Using java language, I am creating an app. It has a screen with a table of 3columns. Each time a user enters the table row and click on Submit button, the row entry should be created as a separate comma-separated file on an android device. So each time when the table gets updated with new entry and clicks a submit button, a new file is getting created on the device file system. So I am looking for the file connectivity to the internal device memory where I could open the files and access it.

I have done the same in Nokia mobiles using J2ME. But for Android, I am not able to find the device file path.

General :: HTC Desire Z - Can't Access System Partition And Formatting Not Possible

Apr 3, 2014

HTC Desire Z (Vision). I S-OFFed how it's described on CM wiki. Latest radio. About month ago I installed CM 10.1 AlterNdromadus. It worked until yesterday, when it unfortunately installed some system update.

After that phone didn't booted anymore. In recovery it says, that it can't access system partition and formatting is not possible.

I tried connect the phone via fastboot in bootloader, but it also doesn't work. Under windows I have it as unknown device and when I tried manually install drivers from google, it says that they are not compatible with the HW (under ROM it worked before).

I tried also install stock RUU rom (extracted the zip and deleted H-BOOT, radio and recovery) from SD-card (PC10IMG.zip). But it also got frozen on system update.

Here you can see error from 4EXT recovery and CRC images from bootloader.

General :: Minimal System With Root?

Mar 7, 2012

I'm after a system.img that's going to allow me to run adb shell sessions as root. That's all I need. I don't need any of the normal phone fuctions or devices. I'd imagine disabling these would overcome any incompatibility issues... but I don't know.

Naturally, it'd be easier if such an image already existed, but I should be able to follow instructions on how to reconfigure a normal system and pack it to yaffs2 image.

General :: Setting System Root As RW Default

Aug 13, 2012

I've mapped my android phone as a network drive using Samba and changed the smb.conf file to show the System Root directory as well. However, system root is default set as R/O so to mange files USING my computer I need to change the permission to R/W using a file manager (such as root explorer). This is annoying, as I have to keep doing this in order to write to certail directories.

I would like the / directory (root) to be mounted as R/W as default so that I can quickly edit files on my PC without having to constantly change it to R/O. I want something that will automatically mount my phone's root dir into rw upon boot, without custom apps/having to manually mount as rw everytime it reboots.

Is it at all possible? We want to put non-button Views in our System Bar. We do have system keys for our specific tablet.

One of my friends tried doing it with no success, but I assume he was looking in the wrong places. I don't know what he knows about the process, so I can't say what we've tried.

We're using Android 4.2 .

I guess I should also mention that we've tried this app - [URL] ..... though we haven't been able to find any info on how he got it to work.

General :: Gain Root On Stock System Image

May 6, 2013

I own a complete backup of all partition of the LG P990 with stock ICS, made it with nvflash with a command like this,

Code:

nvflash -r -read <-partition number-> my_partition.img

for all the partition listed in the partition table.

I guess that in someone of that raw image file, (outputted by nvflash), is located the entry system partition, (PartitionId=23 for the LG P990 ICS partition layout).

It's easy for every linux user to mount the raw image file, simply with 'mount' utility.

Browsing them we can find as already hypothesized the entrie android system partition!

If I copying in it the 'su' executable compiled for my platform, it could work?

General :: Unable To Get Root Access On Evo 4G?

Feb 23, 2012

This is now the second day that I'm trying to root my Evo 4G. So far, I've unlocked the bootloader using the htcdev.com method, but I can't get root access. I think my problem is an old version of hboot (0.99.0001, got it from latest HTC software update [2.3.4]), since the Revolutionary tool is saying that my version isn't supported. I've looked all over for how to update my hboot to 2.15 or 2.16, but nothing has worked. I still have S-ON.

I've tried flashing Amon Ra via command prompt (hangs on "waiting for device") and using the Android Flasher program (hangs on "please wait while your phone is flashed"). I've followed all the steps in the first method on this guide (androidforums com/evo-4g-all-things-root/488901-revised-rooting-gingerbread-2-3-5-dummies-guide.html, but to no avail.

How in the world do I go about rooting this thing? Or even just updating my hboot version?

General :: ADB Root Access On Unrooted Device?

Feb 2, 2014

I have an UTOK 700Q tablet running android 4.2.2 and the manufacturer has made an update to the firmware that requires a full wipe but i want to backup some apps before that.

I've found a way to do a full backup on android via adb on an unrooted device, but is a bit tedious (currently in progress) and while doing it i've noticed that adb has root access:

Now this made me wonder if i can just install titanium backup from adb with root permissions as a system app (or something, not really sure if it's correct, but i hope you understand what i want) so i can backup my apps easier from there.

Also, as a side note, using root checker i see that busybox and su are installed but no SuperUser is found, what does this really mean?

General :: Link2SD Not Obtain Root Access

Jul 29, 2013

I have a rooted Samsung Galaxy Victory LTE and I'm having trouble with Link2SD. I've got a 32GB SD card with a 1.5GB partition, and a 30 GB (or thereabouts) partition. I've verified in SuperSU that Link2SD has root access. But when I start up Link2SD, first I get this toast:

"Link2sd has been granted superuser permissions for an interactive shell." ...ok, that sounds good ...

Then a dialog:

"Select the file system of your sd card's second partition", where I select the Fat32/Fat16 option.

Then I get this dialog:

"Link2SD could not obtain root access.

If you have root access make sure you respond 'Allow' or 'Grant' to the superuser request ."

So what's up with this?

General :: Sprint Galaxy S4 No Root Access?

Jan 16, 2014

So, I have a sprint galaxy s4 (SPH-L720)

BUILD # JSS15J.L720VPUEMK2 ANDROID:4.3

I went through odin v.3 the (COM) spot was lite blue not yellow idk if that matters but it passed and installed cwm custom recovery just like it should, I then installed superuser.zip onto my .sd card and went into custom recover and installed superuser file. the only thing wrong I sawe there is that it failed to verify the signatures? but other than that it said successful/pass all that good stuff and when I turned my phone on and checked the root status it says no root access and superuser not found!!!

Now this is not the first time ive rooted a phone, im no expert by any means but I have successfully rooted and flashed roms to many gs4's with the same computer/odin version/root files...

General :: No Root Programs Can Access Permissions

Apr 7, 2014

I just got a dopo 7" tablet from a relative and for the life of me cannot get it to root. I have been at it since 3-4pm (its 11:10 now) and no matter what apk or .bat rootkit, or windows root exe i have tried from old guides and some new ("can root ANY android device 2014!!!") to YouTube videos.

i have unknown sources checked debugging checked tablet never sleeps/screen never shuts off have it plugged into laptop via the cable the tablet came with usb to micro root master apk failed suggested root-rk29 tab rootkit each step it tried it could not find any of the necessary files needed on my tablet (even after 3 restarts and 3 different methods) root will try to restore data like the programs steps shows but as soon as it says restore started it immediately says restore ended and it gives an X in the circle and wants me to retry (tried 4 times)

tried doomlordz v4 rootkit and same as other rootkit it says the files arnt found and does the alternative methods and SAYS its completed but root checker still says its not

tried key root master mentions something about a cloud program but never roots superoneclick becomes unresponsive for 20mins and does nothing so i have to end task (some says it freezes their phone/tablet) but my tablet acts like nothing is happening.I have tried Googling multiple times only to find results related to 9" version.

I have about reached my limit of patience on this thing..I have 0 knowledge on rooting other than reading up why I would want it or the common steps which did not work obviously...
