My phone (Cherry Mobile Bubble Android 2.3.5) was rooted before through Mobogenie's One Click Root. I don't have any problem my apps gaining root access. But i can't do software update, so i thought that's because of being rooted. So I did permanent root at SuperSU settings, and I have successfully updated my phone. But when I rooted my phone again, I can't gain root access through SuperSu. It always shows "Installation failed". I do have an update zip file on my sd cards root. But to no avail.
Please help. I'm noob regarding on this.
