Realme 9i (RMX3491) Firehose Loader (Snapdragon 680) – Download

Revive your device. Download the official Realme 9i (RMX3491) Firehose Loader. This specialized Snapdragon 680 programmer allows unbricking via EDL mode without authorized account access.

The Realme 9i (4G Model: RMX3491) is powered by the efficient Qualcomm Snapdragon 680 (SM6225) processor. While it is a reliable device, improper flashing, interrupted OTA updates, or trying to root can lead to a “Hard Brick.” In this state, the phone shows no sign of life and is only detected by the PC as Qualcomm HS-USB QDLoader 9008. To fix this, you need the specific Firehose Loader (Programmer) file tailored for the SM6225 platform.

⚠️ Note: This file is for the Realme 9i 4G (RMX3491) only. The Realme 9i 5G uses a MediaTek Dimensity chip and requires a completely different DA file. Do not use this on the 5G version.
