Guide Steps
Confirm the firmware file is an .ofp package. Verify the filename includes your exact Realme model number (e.g. RMX3085, RMX3151).
Do not rename the file — the tool validates the filename against device information.
Run the Realme Flash Tool installer. During setup, it may prompt you to install additional USB drivers — accept all of them.
After installation, launch the tool as administrator.
In the Realme Flash Tool interface:
- Click Choose and browse to your
.ofpfirmware file. - Select the flash mode — Flash All is recommended for a full clean flash. "Flash All (Except Storage)" preserves user data but is less reliable for brick recovery.
Power off your device. To enter flash mode:
- Method A (most Realme devices): Hold Volume Up + Volume Down simultaneously and connect to USB while holding.
- Method B (Deep Test mode): Dial
*#899#in the dialer to enter Deep Test, then tap "Deep Flash".
The device screen may show an Android logo with a USB cable, or remain black. Realme Flash Tool detects the device automatically.
Click the Flash button. The tool validates the firmware, then begins flashing partition by partition.
Flashing typically takes 3–8 minutes.
When complete, the tool shows Flash Success and the device reboots automatically.
First boot after a full flash can take several minutes as realme UI optimizes applications. Leave the device plugged in and undisturbed.
After booting, complete the setup wizard and verify the Android version under Settings → About Device.
Congratulations! Flash Successful!
You've successfully completed all steps. Your device should now be running the new firmware. If it's booting normally — you're done! Check the troubleshooting section below if you encounter any issues.
Troubleshooting & FAQ
Common errors and their solutions. Read this before asking for help.
Most likely causes: wrong flash mode (try both Volume Up+Down and the *#899# Deep Test method), missing or outdated USB drivers, or the bootloader is still locked. Verify your model is supported by Realme Flash Tool — not all Realme models support PC flashing.
The firmware file is not authentic or is for a different device. Only use official .ofp files from Realme's firmware database. If your bootloader is locked, the tool will reject unofficial or mismatched firmware.
Flash again using "Flash All" mode (not "Except Storage") to ensure userdata is wiped clean. If it persists, the firmware may be corrupt — re-download from a verified source.
Realme Flash Tool officially supports only certain models. Using it on unsupported models risks bricking. Always verify support on the official Realme developer portal before attempting.
