Can I install TWRP and root the bootloader locked by Xiaomi Redmi Note 3 Special Edition (Kate)? Sure, you can use the file here. The first step is to downgrade the firmware. Then install TWRP and SuperSU.
I once made a faux pas. I use Kenzo firmware to update Kate. Nightmare! The result is a lost IMEI that has no signal.
- MIUI ROM Global Developer 6.9.29 for KATE (Fastboot Firmware).
- TWRP Recovery ZCX for Kate and Kenzo. Extract the zip file using Winrar then copy the recovery.img file and paste it into the images folder MIUI ROM Global Developer 6.9.29.
- SuperSU 2.78 SR3, install by TWRP Recovery.
- Xiaomi Flash Tool.
- Backup Kate QCN if needed.
