5. Advanced Unbrick (Auth Bypass for MTK)
The INFINIX GT 20 Pro uses MediaTek SLA/DAA security (Secure Boot). SP Flash Tool may show: How to Unbrick INFINIX GT 20 Pro
ERROR: STATUS_SEC_AUTH_FILE_NEEDED (0xC0030005)ERROR: S_DL_GET_DRAM_SETTING_FAIL (0x13BE)
Solution:
- Use MTK Client (Python-based bypass) or Infinix Flash Tool with Auth File.
- Obtain the DA (Download Agent) and Auth File specific to X6851 from INFINIX firmware packages.
- In SP Flash Tool → Options →
Use HW-Auth File → load the auth_sv5.auth file.
Method 2: Boot into Recovery Mode (Stock Recovery)
The INFINIX GT 20 Pro has a recovery partition that can wipe caches or perform a factory reset. Disclaimer: The procedures described below can be risky
Phase 3: The Unbricking Process (Using SP Flash Tool)
This method works for both Soft Bricks and Hard Bricks.
- Launch SP Flash Tool: Open
flash_tool.exe as Administrator.
- Load the Scatter File:
- Click the "Choose" button next to "Scatter-loading File".
- Navigate to your extracted firmware folder and select the
scatter.txt file.
- The tool will populate a list of partitions.
- Select Download Type:
- For Soft Bricks (Stuck on Logo): Select "Firmware Upgrade" from the dropdown menu at the top. This keeps your data but fixes system errors.
- For Hard Bricks/Severe Errors: Select "Download Only". This wipes data but ensures a clean install.
- Warning: Do not select "Format All" unless you are an advanced user, as this can wipe the phone's NVRAM (IMEI numbers) and make the device unusable.
- Connect the Device:
- Power off the phone completely.
- Do not hold any buttons yet.
- Click the "Download" button in SP Flash Tool (it should start blinking yellow/green waiting for a connection).
- Plug the USB cable into the phone.
- If the connection is successful, the tool will detect the device and the progress bar will start moving.
- Troubleshooting: If nothing happens, try holding the Volume Up or Volume Down button while plugging in the cable.
- Wait for Completion:
- Do not touch the phone or cable until you see a green circle with a checkmark saying "Download Ok".
- Disconnect and Boot:
- Unplug the phone.
- Press and hold the Power button for about 10-15 seconds to turn it on.
- First Boot: The first boot after flashing stock firmware usually takes 5–10 minutes. Be patient.
What If Nothing Works? (Hardware Level)
If SP Flash Tool still fails with "BROM ERROR: S_BROM_CMD_STARTCMD_FAIL," your phone might have a corrupted preloader or a hardware short. Clear warnings about warranty voiding
- Contact INFINIX Service Center: The GT 20 Pro is relatively new; it should be under warranty. Tell them "firmware update failed." Do not mention rooting.
- Use the Test Point method: As a last resort, you can short specific test points on the motherboard to force BROM mode. Warning: This voids warranty and requires disassembly.
Conclusion
Most INFINIX GT 20 Pro bricks can be recovered using SP Flash Tool + correct firmware + MTK drivers. For auth errors, use MTK Client or official INFINIX Flash Tool with provided auth file. If the device is completely unresponsive (no PreLoader), a hardware test point or professional repair is required.
Recommended first step: Boot to recovery → factory reset. If that fails, proceed with SP Flash Tool in Download Only mode using stock firmware from INFINIX’s official update server or a trusted community source.
10. Legal, Warranty & Safety Notices
- Clear warnings about warranty voiding, data loss, and legal considerations.
- Minimal first-aid tips (disconnect, battery removal advice if applicable).
Method 1: Force Restart (Soft Brick)
If the phone is frozen or boot looping:
- Press and hold Power + Volume Up for 15–20 seconds.
- Release when the INFINIX logo appears.
- If it boots normally – you’re done.
