I have tried to root lenovo a7000 a with kingo root application with no success. My computer will be infected due to this method as the download page for apk file forces me to download malicious file.SRS Root claims to support this device but is SRS Root safe? Is there any other way to root my device ?
Here's a link to the recovery file: A7000-CWM-Final.zip
Once you've flashed the CWM recovery, you'll need to get the latest version of SuperSU and flash it by booting into CWM recovery (do that by turning the phone off, depressing the volume keys and then pressing the power button until you boot into CWM) and selecting the ZIP update package.
You can get the latest version of SuperSU in ZIP format here: http://download.chainfire.eu/supersu
According to maxritz, you'll need to delete the
recovery-from-boot.p file from the root filesystem
/system as it may overwrite the recovery and undo your changes. You could do that by using a file manager app like AROMA Filemanager that works in Android recovery environment. Usage instructions and download links for AROMA are available here.
NOTE: Rooting your phone will most likely result in loss of warranty.
First, I’d like to recommend Framaroot. But it didn’t work for you. So try iRoot for PC version. iRoot has two versions for Android rooting, which are both safe and fast. Basically, the PC version has the higher success rate. But if your Lenovo A7000 is with Android 5.1 and up, it may be still useless.
