Why Use SP Flash Tool for the OPPO A9 PCAM10 / PCAT10?
The OPPO A9 (PCAM10 / PCAT10) runs the MediaTek Helio P70 (MT6771) — a 12nm octa-core chipset. Because OPPO implements a strict secure boot (SLA/DAA) system, flashing stock firmware via SP Flash Tool requires combining the tool with an MTK Auth Bypass tool. SP Flash Tool communicates directly with the MT6771 Boot ROM (BROM) at the hardware level, completely bypassing the ColorOS environment. This makes it the ultimate utility for restoring completely bricked devices, fixing boot loops, or cleaning corrupted partition tables, without needing an officially unlocked bootloader.
SP Flash Tool accesses the MT6771 hardware directly via BROM. Bootloader lock status is completely irrelevant.
If your OPPO A9 is stuck in a boot loop, shows recovery errors, or is completely dead, BROM-level access allows a complete flash.
Flash raw factory images to clean corrupted sectors, repair damaged partition tables (PMT), and fix boot loops.
Restore the official stock ColorOS firmware to bring the device back to its fresh out-of-the-box factory state.
How to Flash the OPPO A9 PCAM10 / PCAT10 — Quick Overview
A condensed step-by-step summary specific to the OPPO A9 PCAM10 / PCAT10. Follow the full SP Flash Tool guide for screenshots, an interactive progress checklist, and complete troubleshooting.
-
Charge your device and back up data
Charge the OPPO A9 to at least 60%. Back up all photos, contacts, and files u2014 Format All + Download will erase everything on the device.
-
Install the MediaTek VCOM USB driver
Download and install the MTK VCOM USB Preloader driver on your Windows PC before connecting the phone. Without it, Windows cannot detect the A9 in BROM mode.
-
Extract SP Flash Tool
Extract SP Flash Tool v5.2216 or newer to a path with no spaces (e.g. C:\SPFlashTool). Right-click flash_tool.exe and choose Run as Administrator.
-
Extract firmware and load the scatter file
Extract the OPPO A9 firmware ZIP. In SP Flash Tool, click the Scatter-loading button, navigate to the extracted firmware folder, and select MT6771_Android_scatter.txt.
-
Select your flash mode
Choose "Format All + Download" for a complete clean restore, or "Download Only" (with userdata unchecked) to attempt a system repair without wiping personal data.
-
Enter BROM mode and connect
Power off the OPPO A9 completely. Click Download in SP Flash Tool first, then connect the Micro-USB cable while holding the Volume Down button. The tool will detect the MT6771V Boot ROM automatically.
-
Wait for the green OK circle
SP Flash Tool flashes all selected partitions and displays a green circle with OK when complete. Disconnect the USB cable and power on the device.
SP Flash Tool and MTK Bypass utilities require Windows 7, 8, 10, or 11. Run all software as administrator.
You must install both the MTK VCOM drivers and the LibUSB filter. The filter is crucial for capturing the OPPO BROM connection.
A free utility like MCT MTK Bypass, MTK Meta Utility, or similar is mandatory to bypass OPPO's MT6771 secure boot (SLA/DAA).
Extract the complete firmware containing MT6771_Android_scatter.txt. Ensure it matches your PCAM10 or PCAT10 model.
Ensure the built-in 4020mAh battery has sufficient charge. If the device dies mid-flash, it can result in a physical storage brick.
Flashing will wipe all user data. Back up anything essential before starting.
Deactivate Windows Defender and any local antivirus temporarily. They will flag MTK bypass tools as false positives.
Finding the Scatter File for MT6771V/CT
The OPPO A9 (PCAM10 / PCAT10) uses the MT6771 chipset. Its partition layout mapping file is included in the stock firmware and is named:
MT6771_Android_scatter.txt
This file is inside the firmware ZIP. After extracting, look for any file ending in _scatter.txt or _scatter.xml. If your package has no scatter file it is not compatible with SP Flash Tool — find the correct firmware package before continuing.
Caution: The OPPO A9 (2020) is a completely different device powered by the Qualcomm Snapdragon 665. Do not confuse the 2019 OPPO A9 (PCAM10 / PCAT10 / MT6771) with the Snapdragon-based A9 2020. Attempting to load a MediaTek scatter file on a Qualcomm device will fail, and flashing incompatible firmware will result in a hard brick. Always check your model number in Settings → About Phone or recovery mode before continuing.

Which Flash Mode Should You Use?
Format All + Download
Wipes the entire device and flashes everything fresh. Best for fixing bootloops, stuck logo, or performing a clean firmware restore. All personal data will be erased.
Erases all dataDownload Only
Flashes only selected partitions. Uncheck userdata and cache in the partition list to preserve personal data. Best for repairing a failed ColorOS OTA update.
May preserve dataFirmware Upgrade
Attempts to upgrade firmware while keeping data. Only reliable between very similar ColorOS versions. Not recommended for major version changes.
Least reliableOPPO A9 PCAM10 / PCAT10 — Important Notes
The OPPO A9 (PCAM10 / PCAT10) is heavily locked down. Official bootloader unlocking is not supported by OPPO for this model, which makes flashing stock firmware via the MTK hardware interface (BROM) the only way to recover from system corruption.
Because the PCAM10 and PCAT10 are primarily Chinese market models, flashing a global CPH1938 ROM can result in a hard brick or lose cellular network functions due to partition differences. Ensure you keep backups of your nvram and nvdata partitions if possible, as they contain device-specific calibration and IMEI numbers.
Always perform the LibUSB driver filter installation step. Without the LibUSB filter routing your device connection to the bypass utility, the auth bypass tool will fail to capture the BROM signal, leading to SLA/DAA authentication errors in SP Flash Tool.
Common Errors on the OPPO A9 PCAM10 / PCAT10
BROM ERROR: S_FT_ENABLE_DRAM_FAIL (4032)
The loaded firmware does not match the board revision or the memory init block is wrong; recheck that the package is specifically for OPPO A9 PCAM10 / PCAT10 and reload the correct scatter file.
BROM ERROR: S_CHIP_TYPE_NOT_MATCH (3168)
The firmware package is for another chipset family; switch back to a MediaTek MT6771 ROM package and never mix files from OPPO A9 2020 or other OPPO models.
STATUS_SEC_IMG_TYPE_MISMATCH
A signed partition image from another variant or software branch was selected; download a board-matched stock ROM and replace the mismatched image set.
STATUS_BROM_CMD_STARTCMD_FAIL
The preloader handshake failed because the driver, cable, or timing is wrong; reinstall the MTK driver, use a direct motherboard USB port, and reconnect the powered-off phone after pressing Download.
PMT changed for the ROM; it must be downloaded
The partition map on the phone differs from the loaded ROM package; use Firmware Upgrade only with the exact stock package for this board and avoid random partition combinations.
DA HASH MISMATCH
The download agent or firmware component does not match the expected security profile; switch to a cleaner stock package and use the bundled or known-compatible SP Flash Tool release.

Frequently Asked Questions — OPPO A9 PCAM10 / PCAT10
Format All + Download mode wipes all personal data, apps, and settings. If you only need to repair a corrupted system partition, use "Download Only" mode and uncheck the userdata partition u2014 this preserves personal data as long as the PRELOADER partition is still intact.
No. SP Flash Tool communicates directly with the MediaTek MT6771V Boot ROM (BROM) at the hardware level, completely bypassing Android and the bootloader. Bootloader lock status is irrelevant when flashing via SP Flash Tool.
Yes, in most cases. As long as the MT6771V USB Boot ROM is physically intact, SP Flash Tool can detect the chip and restore the firmware even if the device shows no signs of life. It cannot recover from physical damage to the USB port, eMMC storage, or other hardware components.
PCAM10 is the standard Chinese domestic market variant of the OPPO A9. PCAT10 is a regional sub-variant sold in some Asian markets. Both share the same MediaTek Helio P70 (MT6771V) chipset and use the same SP Flash Tool procedure. Always confirm your exact model in Settings u2192 About Phone before downloading firmware.
Download firmware specifically labelled for PCAM10. The OPPO A9 shipped with ColorOS 6 (Android 9). Some units received a ColorOS 7.1 (Android 10) OTA update. Using firmware intended for the CPH1938 (Snapdragon variant) or the OPPO A9x will cause a chipset mismatch and brick the device.
Yes. Use SP Flash Tool v5.2216 or newer. On Windows 11, you may need to disable Driver Signature Enforcement in Advanced Startup u2192 Troubleshoot u2192 Advanced Options if the VCOM driver installation fails. Always run flash_tool.exe as Administrator and use a USB 2.0 port directly on the motherboard.
