⚠️ Flashing Risks & Disclaimer
Because this model uses the legacy MediaTek MT6580 platform, flashing an incorrect preloader or scatter layout can cause deep bricks where the phone no longer enumerates properly over USB without specialized repair equipment. A full scatter‑based flash may overwrite boot, system, userdata, and NVRAM partitions, and interrupting the process or loading images from another MT6580 device can lead to loss of IMEI, baseband issues, or permanent non‑booting behavior.
SP Flash Tool also allows low‑level operations such as formatting, which, if misused, can erase calibration and security data that are not contained in typical public firmware archives. All actions are performed at the user’s own risk, and a full backup of NVRAM/NVDATA and user files is strongly recommended before flashing whenever possible.

Flashing Requirements
This MT6580 device expects a classic MediaTek flashing workflow, typically using SP Flash Tool and a scatter file contained inside the ZIP archive. A Windows PC is strongly recommended, because most public MT6580 tools and drivers are distributed for Windows and expect VCOM/Preloader USB drivers to be installed.
- Install MediaTek VCOM or CDC drivers so that the powered‑off Onyx 1S is detected when connected in preloader mode.
- Extract the Eurostar_Onyx_1S_MT6580_09222016_6.0.zip file on the PC to reveal the scatter file (usually MT6580_Android_scatter.txt) and partition images.
- Use only the scatter and images from this archive for this phone; do not mix files from other MT6580 models to avoid NVRAM or modem incompatibilities.
- Whenever possible, back up NVRAM and user data partitions before flashing, because a full format + download cycle can erase IMEI and configuration data.
- Ensure the battery has sufficient charge (at least 50%) and avoid USB hubs or loose cables during the flash.
How to Flash the Firmware
The outline below describes a typical high‑level SP Flash Tool workflow for installing the Eurostar Onyx 1S Android 6.0 firmware on an MT6580 device.
- Download the Eurostar_Onyx_1S_MT6580_09222016_6.0.zip archive and extract it on the PC, locating the MT6580 scatter file and associated partition images.
- Install MediaTek USB VCOM drivers, then open SP Flash Tool on the PC and use the “Scatter‑loading” option to load the MT6580 scatter from the extracted firmware folder.
- After confirming the partition list, choose an appropriate mode (for example, “Download Only” for a typical system restore), and deselect preloader if a safer partial flash is preferred.
- Power the phone off completely, click “Download” in SP Flash Tool, then connect the Eurostar Onyx 1S to the PC via USB so that preloader mode is detected and the flash begins.
- Wait for SP Flash Tool to complete and show a success message, then disconnect the cable and power on the device; first boot after a full flash can take several minutes while Android 6.0 rebuilds caches.

Frequently Asked Questions (FAQs)
Is this firmware only for the Eurostar Onyx 1S MT6580?
The archive name explicitly references Eurostar_Onyx_1S_MT6580_09222016_6.0, indicating it targets the MT6580‑based Onyx 1S and should not be used on other brands or MT6580 models with different hardware layouts.
Does this ROM include a scatter file for SP Flash Tool?
Standard MT6580 factory ROM archives for tools like SP Flash Tool normally include an MT6580_Android_scatter.txt file together with partition images, and the naming of this package strongly suggests a similar layout, even though the scatter filename is not visible in the HTML snippet.
Will flashing this ROM update Android or just restore it?
This package is labeled “6.0” and dated 2016‑09‑22 in the filename, so it is intended to install or restore Android 6.0 Marshmallow, not to upgrade the device to a newer major Android version.
Can this firmware fix bootloops or a stuck logo on the Onyx 1S?
A correct full flash using SP Flash Tool can often resolve software‑induced bootloops or stuck logo issues by replacing corrupted system and boot partitions, but it cannot fix hardware faults or issues caused by damaged storage chips.
Is bootloader unlocking required on this MT6580 device?
Classic MT6580 phones like the Eurostar Onyx 1S typically use preloader‑based flashing through SP Flash Tool and do not require a user‑visible OEM unlock toggle, but enabling USB debugging while the phone is still bootable can help with preliminary backups.
