HDC S7 SM-G9350 is a Samsung Galaxy S7 edge MT6580 clone running Android 5.1 or 6.0 on a quad‑core MediaTek platform with 1 GB RAM and 4 GB eMMC. On this class of clone devices, users frequently encounter bootloops after failed flashing, soft‑bricks from wrong ROMs, or instability following modifications, and reinstalling the correct scatter‑based firmware can help restore a clean system.
The three packages listed below are official‑style HDC stock ROMs for this model, built for MT6580 and distributed as SP Flash Tool scatter firmware for Android 5.1 Lollipop and Android 6.0 Marshmallow.

⚠️ Flashing Risks & Disclaimer
HDC S7 SM-G9350 uses MediaTek MT6580 hardware while the genuine Samsung SM-G9350 uses Qualcomm Snapdragon 820, so installing official Samsung Odin firmware on this phone is not compatible and can hard‑brick the device. Even among MT6580 clones, different board revisions and LCD/touchscreen configurations exist, and flashing a mismatched ROM (for example, wrong build ID or preloader) can cause loss of display, no boot, or complete non‑detection over USB.
All three ROMs below are full scatter packages that typically erase user data and may overwrite the preloader partition depending on SP Flash Tool settings, so backups are strongly recommended where possible. These firmware files can help resolve software‑level issues such as bootloops, system app crashes, or failed OTA attempts, but they cannot correct hardware defects like damaged screens, bad power ICs, or failed eMMC. Flashing is done at the user’s own risk and may void any remaining informal warranty from the seller or shop.

Flashing Requirements
- Operating system: Windows 7 or later recommended, with administrator rights to install MTK drivers and run SP Flash Tool.
- Flashing tool: Smartphone Flash Tool (SP Flash Tool v5.x) with MT6580 support, configured to use the scatter file included in the chosen HDC S7 SM-G9350 firmware package.
- Drivers: MediaTek VCOM / preloader USB drivers or dedicated HDC MTK USB drivers installed so the phone is detected in bootrom or preloader mode.
- Bootloader status: These are service‑oriented stock ROMs; flashing via SP Flash Tool normally does not require user‑visible bootloader unlock on MT6580 clones, but secure variants are possible in rare cases.
- Battery & cable: At least 50% battery charge and a reliable USB cable/port to minimize risk of disconnection during the download phase.
- Data backup: Internal user data and installed apps are usually erased by a full scatter flash (especially with “Firmware Upgrade”), so back up photos, contacts, and other files to a PC or SD card when the device still boots.
- Device verification: Confirm that the phone actually reports MT6580 hardware and an MTK‑style build string (for example, ALPS.L1.MP6 or hero2qltechn) using tools or Android settings; do not attempt to flash these ROMs to genuine Qualcomm SM-G9350 units.
- ROM selection: If the original phone ran Android 5.1 and stability is the main goal, one of the 5.1 builds (base or A.A_Y7B0623) is often safer; if it previously reported Android 6.0 with a 2016‑12 build date, the V0.0.2_20161205_6.0 package is a closer match.
How to Flash the Firmware
- Download and extract the correct HDC ROM: Choose the firmware that best matches the device (for example, the V0.0.2_MT6580_20161205_6.0 package if the phone previously ran Android 6.0) and extract the ZIP on the PC to reveal the MT6580 scatter file and partition images.
- Install MTK drivers and prepare SP Flash Tool: Install MediaTek VCOM / HDC USB drivers, then download and run a compatible SP Flash Tool build; inside the tool, open the “Download” tab and load the scatter file from the extracted HDC S7 SM-G9350 firmware folder.
- Select flash mode and partitions: For full recovery on this MT6580 clone, select “Download Only” or “Firmware Upgrade” depending on the situation, leaving all default partitions checked unless there is a specific reason to preserve userdata; avoid changing preloader settings unless confident about board compatibility.
- Enter preloader mode and start flashing: Power off the phone, disconnect and reinsert the battery if removable, then click the “Download” button in SP Flash Tool and connect the device via USB; if needed, hold Volume Up or Volume Down so the PC detects the MT6580 preloader and the download begins.
- Wait for completion and first boot: After the progress bar reaches 100% and SP Flash Tool shows a green confirmation dialog, disconnect the cable and boot the phone; the first boot after installing a full Android 5.1 or 6.0 stock ROM on this model can take several minutes while it initializes the system and optimizes apps.

Frequently Asked Questions (FAQs)
How can the HDC S7 SM-G9350 clone be distinguished from the real Samsung SM-G9350?
The clone runs on MediaTek MT6580 and typically reports MTK build IDs such as ALPS.L1.MP6 or hero2qltechn, while the genuine Samsung SM-G9350 uses Snapdragon 820 and is flashed with Samsung Odin firmware. Physical similarities can be close, so checking SoC and build strings via software or reading info with an MTK tool is important before flashing.
Which of the three ROMs is safest for a bricked device with unknown previous build?
If there is no record of the original version, the A.A_Y7B0623 5.1 ROM is often used as a general‑purpose repair firmware for this clone family, while the V0.0.2_20161205_6.0 build targets Marshmallow units produced later in 2016. When possible, matching the project string or compile date to a backup or box log is safer than guessing.
Can these MT6580 scatter ROMs be flashed with Samsung Odin?
No. Odin is designed for genuine Samsung Qualcomm/Exynos firmware and cannot flash MT6580 scatter packages. HDC S7 SM-G9350 clone firmware must be installed with an MTK‑oriented tool such as SP Flash Tool using the provided scatter file.
Will flashing the Marshmallow ROM upgrade performance compared to the Android 5.1 builds?
Moving from a 5.1 firmware to the 20161205 6.0 ROM changes the Android base and system partition layout but does not change the underlying MT6580 hardware limitations. Any perceived performance or stability differences will depend on how this particular build handles memory and pre‑installed apps rather than raw CPU capability.
Does SP Flash Tool require an unlocked bootloader on this MT6580 clone?
Clone devices like HDC S7 SM-G9350 generally allow service flashing of stock ROMs over preloader mode without an explicit OEM unlock step. However, secure boot variants exist in the MTK ecosystem, so mismatch or authentication errors can still occur if the firmware is not built for the exact hardware revision.
What common errors may appear when flashing these ROMs?
Typical SP Flash Tool issues include BROM or S_FT_ENABLE_DRAM_FAIL errors from incorrect scatter or DA settings, and status errors related to bad or missing VCOM drivers. Ensuring proper MTK driver installation, using a matching firmware for the board, and trying alternative USB ports usually resolves many of these problems.
Will flashing affect IMEI or network behavior?
Full scatter ROMs can overwrite NVRAM/NVDATA on some packaging styles, which may clear IMEI or radio configuration if those partitions are included in the flash. Many HDC firmware guides recommend backing up NVRAM or excluding it from the download list when only system repair is needed, then repairing IMEI with appropriate tools if required.
Can OTA updates still be used after installing one of these packages?
Clone devices rarely receive structured OTA updates comparable to official Samsung firmwares, so these HDC ROMs are typically used as static service images rather than part of an OTA upgrade path. Once a suitable ROM is installed and stable, future maintenance is usually done by reflashing rather than by incremental OTAs.
