Custom recovery for the global Redmi Note 9 Pro, codename joyeuse, with the name pointing to TWRP 3.4.2b for Android 10. Supplied as a 32.9 MB zip that should contain the recovery image. Technicians use it to take full partition backups before repair, wipe user data, flash firmware packages or extract files. Installation needs an unlocked bootloader and fastboot. The global Note 9 Pro is distinct from the China Note 9 Pro 5G, so confirm joyeuse on the device before flashing, or the phone may fail to boot into recovery.
