Using TWRP, one can easily clean Wipe, Cache, and Data after flashing any image file to reflect the changes and rectify minor errors due to cache.
For installing the TWRP, your Lenovo K9 phone must have the Unlocked bootloader. That means you have to firstly unlock the bootloader to root your device as well doing any customization.
Rooting and flashing the Custom ROM firmware, certainly without any doubt voids the warranty of your device and AndroidWeblog.com in no way will be held responsible for warranty void or your bricked device.

adb reboot bootloader
Step 2: Now, open the Adb Terminal in PC, and then just enter this command:
fastboot oem unlock-go

Steps to Flash/ Install TWRP on Lenovo K9
Step 1: Assuming you have already downloaded the platform-tools from Android SDK (SDK Manager) platform-tools on your PC. The platform-tools contains the required ADB and fastboot binaries.
Step 2: Make sure that the drivers are installed on your computer. Then, skip to the next step.
Note: If Developer Settings and USB Debugging settings are already enabled on your device, as suggested in Prerequisite section, then simply skip the Step 3 and Step 4, and follow Step 5 directly.
Step 3: Now, enable the developer settings on your Lenovo K9 Device. To achieve the same, just navigate to the Settings -> About and then find the ‘Build Number ‘, and then tap on ‘Build Number’ for 7 times, this will enable the developer settings on your device.
Step 4: If you have USB Debugging already, then skip this step. If you have not, then open the Developer Options and then enable the USB debugging option.
Step 5: Now, open the command prompt in computer/ ADB Terminal, and simply type the command:
fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img
and then type:
adb reboot bootloader
Step 6: Your device should have not entered into fastboot mode. Now copy the TWRP.img file downloaded in prerequisite section, to the same folder where ADB and fastboot binaries are located. Rename the file to ‘twrp.img’ and then enter this command:
and then run this command, type:
Step 7 (Important): Some devices might not replace the custom recovery automatically during the first boot. You can search Google for key combinations to enter your device into recovery mode. After running the ‘fastboot reboot’ command, press and hold the proper key combination to enter the device into TWRP Mode. Once the device boots to TWRP mode, the TWRP will automatically patch the stock ROM, to prevent the chances of replacing TWRP with Stock Recovery.
After typing fastboot reboot, hold the key combo and boot to TWRP. Once TWRP is booted, TWRP will patch the stock ROM to prevent the stock ROM from replacing TWRP. If you don’t follow this step, you will have to repeat the install.
