Realme 9i (RMX3491) Firehose Loader (Snapdragon 680) – Download
| Views: 3 | Basic | |
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.
