Hi there,
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)
Any other ideas?
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)?
Thank you for your help,
Tobias

are you rooted check with root checker if yes(as you alredy said)
install super su or super user to gain root acces controls
but iam not sure from your question you are rooted or not or are you trying to root
P.S deleting super su will not unroot you

Root checker says: "Sorry! This device does not have proper root access."
Right now, I am NOT rooted. So the device WAS rooted and then /system/xbin/su was deleted. Meaning: everything else is in place (SuperUser, Busybox, etc.) but I cannot execute anything as root, because I cannot switch the user to root (what su does). Although I am not really unrooted, I cannot do anything any more. So basically I would like to re-root my device.
The goal is to get fully rooted again.

I don't think you can root without any pc
If your phone has recovery just flash the root files :thumbup:

Have you tried looking in /system/bin/su instead of /system/xbin/su
As title, I'm trying to root a development board running 4.2.2. I do have root access and put busybox and su, but my problem is that whenever I start apps that require root access, superuser never gives me prompt asking whether root access is allow (yes, my setting in Superuser is to prompt for every apps that require root), as a result, the app would not run reporting that my device is not rooted. As an example, when I trying to run droidvncserver, it would tell me "could not start server", but if I start it as root on a shell, it would run and start server, this leads me to think that droidvncserver is not requesting root access or Superuser does not know that droidvncserver needs root access. I'm pretty sure I'm missing something in my system, but what is it. All this works on a rooted phone, but not on the development board. I've read through some of the rooting script for other phones, mostly include remounting /system as rw and put busybox and su onto the system, and that's what I've done on the board, but there's just no connection between those root-require apps and superuser. Anyone knows what I'm doing wrong/missing?
i am trying to root some cheap tablet. its based on arm9 wm8800 dual core ,running android 4.4. in developers options there is option to set super user permission (always ask,etc) but it doesnt do anything,when i ran root checker it shows its not rooted,and when i installed superuser from play store it says something about SU binary also apps that require root wont work etc.. so i tried several other options.. after running z4root there's no more su binary problem. root checker shows its not properly rooted,it shows that su binary is there in system/xbin/su but there's red text with some permissions .like i need to fix them,but dont know what to do.. i have rooted many devices,but this is hard.. any help??
I had rooted Celkon Q 500 with some method, I do not remember exactly. May be Root Genius. For some reason I unrooted using SuperSu. I wanted to re-root. But I am finding it difficult. ( I have not got any OTA update after rooting)One root checker says it is rooted, another says it is not. I can explore files in root explorer of ROM Tool Box Pro I had installed earlier. But I can not reboot through ROM Tool Box Pro. One root checker provided me this information : subinary available via $PATH null null, then in the next line it says : -rwsr -sr -x root root, subinary location is system/bin/su. Second thing it says : I have installed two busybox one at (a) data/local/busybox and another at /system/xbin/busybox. I had tried to un-install and re-install SuperSu and Busybox 2/3 times. Then after opening Supersu I got an erratic message : su binary needs updating and when Itried to update it , it failed several times. One root checker app says ADB root is available, Root Genius says root available. So, I am quite confused. I do not know how to go about it. I will be thankful, if somebody guides me in right direction.:crying: (I also found a root checker app said SELinux enforcing.)
I rooted my Micromax Bolt q324with kingoroot pc software successfully but after a few days i cant able to get root access for some apps like when i install a new root app it asks me for permission then i tap grant but the app shows unable to gain root access. how to fix this issue i tried flashing my phone with stock ROM then again rooting it with kingoroot but again no luck i was unable to gain root access for some apps but when i check root access with root checker it says root access properly installed and i can go to terminal with root access but when i try to mount system as rw it shows ''Mount: operation not permiited" how to fix this issue!!!
And yes the phone is a spreadtrum sc7731 chipset device so the rom file is in .pac format but i figured that how to flash it.So i am willing to install a Custom ROM if you provide me the link of it.......

I would try this. Kingoroot and Kingroot both have their own superuser app that doesn't always work that well.
