Absolutely not. The chipset is the same, but PCB layout, eMMC chip vendor (Samsung vs. Hynix), and partition mapping are board-specific. Using a cross-model scatter file will at best corrupt the nvram (losing IMEI) and at worst brick the device.
Use a hex calculator (e.g., HxD or command line):
# For ANDROID partition example:
Start = 0x4200000
Size = 0x27E00000 (from your scatter)
End = 0x4200000 + 0x27E00000 = 0x32000000
# Ensure no overlap with CACHE (starts at 0x2c000000) – it's fine if sequential.
Once you have a verified MT6755_Android_scatter.txt, follow this safe flash procedure.

[Revised] How to use SP Flash tool to flash Mediatek firmware
Different MT6755 phones (e.g., a Leagoo T5 vs. a BLU R1 HD) have drastically different partition tables. Using the wrong scatter file can overwrite the preloader—the first code executed by the CPU. A corrupted preloader = a dead phone (no charging, no boot, no detection).
In MediaTek’s ecosystem, a scatter file (extension: .txt) is a human-readable, structured configuration file that describes the exact memory layout of a device’s eMMC (embedded MultiMediaCard) or UFS storage.
Think of it as a GPS map for the SP Flash Tool. Without it, the tool would have no idea where to place the bootloader, kernel, Android system, or user data.
Leo connected the phone via USB. Nothing. He held the volume buttons. Nothing. He jumpered the test points on the motherboard—a tiny short between two capacitors—and finally, the PC chimed. USB Device Recognized: MTK USB Port (COM10). The preloader was alive, barely.
He opened SP Flash Tool v5. He needed the scatter file for the exact MT6755 variant—not the MT6755S (clocked lower), not the MT6755M (which had a faster GPU). This was the vanilla Helio P10.
A scatter file is a text-based map of the eMMC storage. It tells the flashing tool: "Here is the preloader. Here is the partition for NVRAM (where your IMEI lives). Here is the boot image, the recovery, the system. Do not cross the streams."
Without the correct scatter file, you’re a surgeon operating without an anatomy chart.
Leo found a generic "MT6755_Android_scatter.txt" on a Russian forum. He loaded it. The tool populated partitions: pgpt, proinfo, nvram, protect1, protect2, lk, boot, recovery, secro, system, cache, userdata.
He clicked Download (the infamous button that erases then writes).
