[Update: This method is working for some, and not working for others. If you are in the latter group, try out the rooting guide for Micromax A110. It has been reported working on Karbonn A21 too. You can even install the drivers in the exact same way, so all the steps are ditto for A21.]
Let's talk about what you are here for: Rooting the Karbonn A18. The guide is quite easy and the main part is installing the drivers. Before you start off with the guide, you might want to learn what rooting is, and its pros and cons. Without wasting your time, let's roll down the step you need to perform:
Downloads Required: A21 Drivers and Root Tool.zip
- Extract the zip file you downloaded above.
- Connect your phone to the PC using USB and install the drivers.
- Open unlockroot and let it install. (If your download stucks, download the offline version!)
Note: Your anti-virus might classify it as a threat (as it can potentially harm your phone), but don't worry, there is no virus in the file. Just deactivate your anti-virus temporarily.
- Start Unlockroot. It should detect your phone as drivers have already been installed.
- Click the big green root button. (Ignore any (if there's any) message that says your phone is already rooted.)
Click the Root button!
- Don't do anything now. On top of all, don't disconnect your device during the process. Just let it complete. You may use a laptop if you fear power interruption while using your PC.
- Once the process is completed, your phone will be rebooted.
- Disconnect and have fun with your rooted device!
