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.

no way to get a390 rooted
hi! i'm trying to root and setup a recovery on this phone but i cannot do it...
tried with no luck:
- scoutdriver73's method: sp flash tool hint me that it can download only a full image
- root with recovery method: script doesn't recognize when i confirm on smartphone for the reset, same for root option in mtk droid tools
- this guide http://forum.xda-developers.com/showthread.php?t=2332783 for extract boot.img and recovery.img and fix root permission with mtk droid tool, i get this error: 0 [main] gzip 4324 find_fast_cwd: WARNING: Couldn't compute FAST_CWD pointer when i load my recovery.img on mtk tool.
i noticed there is a size difference between TWRP img i downloaded from web (5640Kb) and the one i extrated directly from phone (6144kb)
any suggest?
thanks
(LATE REPLY) This is how I rooted my a390
I noticed the post is 10 months ago, but I'm replying right now because there may be other users hunting for root solutions for this device.
How to root your Lenovo a390:
1. Download Framaroot: http://forum.xda-developers.com/showthread.php?t=2130276
Framaroot is an Android app created by XDA user alephzain. It allows you to root your device directly from your Android device-please click on link above to view full compatibility list. Download and Install this app. If it says "Installation blocked", go to your phone's Settings>Security and tick the "Unknown Sources" box. (Believe me, there are n00bs )
2. Open Framaroot. For the a390, there is only one exploit-Boromir, since it's a Mediatek powered device. Select Boromir.
3. Now you see two buttons: Install Superuser and Install SuperSU. You need to select only one of them. Framaroot will then root your device and install Superuser/SuperSU. (Superuser/SuperSU are apps which control root operations on your device ie. ensure no app uses root features without your permission-it is a MUST.)
The choice is up to you, but I'd recommend Superuser since it's like the Industry standard of rooted Android phones.
4. Reboot your phone. You'll find Superuser installed. Open it, swipe from left to right to access Superuser settings. The su binary is outdated and it'll appear in a red font. Tap it to update su binary.
This is proof enough that your phone is rooted, but if you really need to see, here's one more step.
5. Install Root checker from Google Play Store: https://play.google.com/store/apps/details?id=com.joeykrim.rootcheck
Run this app, and if your phone is rooted, Superuser will come up automatically asking you whether Root Checker should be granted permission- press Yes and root Checker will deliver the result.
That's it-congratulations, you've rooted your a390 without any pain. Now you can flash a recovery, install Busybox, overclock your phone, get rid of the dumb apps Lenovo has included with the a390.... Enjoy! :laugh:
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
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.)
After rooting we instal busybox and SuperSU (or Superuser) and avail the benefits of rooting. When we unroot through SuperSU, is it possible that 'su' still remains inside '/system' folder? I came across a strange phenomenon : I rooted my Celkon Q 500 ( by Root Genius or One-click method or something else, I do not remember) and installed many root apps. After somedays, I decided to unroot, I uninstalled super su, busybox. Then, I tried to root it again. But, I noticed that one root checker says ur device is rooted(specifically through Root Genius PC software I got the message rooted and pressed the 'unroot' button, but it said failed), 2nd root checker says it is non-rooted, 3rd one says it has root access through ADB. I checked 'su' is present in some folder inside '/system', which could not be deleted , because I think, I do not have RW privilege. I had tried many method to root it again, but all failed. When I open Supersu, it throws an immediate message that 'su binary' needs to be updated and when I try it fails everytime. Can anyone meke me understand, what is the real proble.? Celkon Q 500 is Broadcom chip based, running android 4.4.2. Also I found One message in the root checker that "SELinux enforced".

reinstall super su from play store go to settings in super su app and unroot there
selinux enforced means that your kernel is not permissive. has nothing to do with root
