Installation Guide for Flashing TWRP

DO NOT FLASH TWRP IN BOOT PARTITION. Follow like in this method.

1. Save RK-Kernel-2.0-Twrp.zip in your nabu device.
2. Reboot to bootloader
3. fastboot boot twrp.img
4. Goto Advanced in twrp options then click "Flash current TWRP" as shown in the image, then hit back . Do not reboot.

5. Install the kernel.zip in recovery then reboot to system.

6. Now you have recovery installed as permanent. Easily accessible by adb/fastboot command or volume keys.

Note: Be sure not to flash any other recovery without TWRP patch which will otherwise lead to bootloop. You will need to restore stock boot.img, dtbo.img and vendor_boot.img to restore partitions.
