Keep holding the button until the screen displays an "Upgrading Software" progress bar or the indicator LED begins blinking rapidly. Release the button and wait for the process to finish. Safety and Best Practices

The final step is pushing your newly created MstarUpgrade.bin back to the device. Format a USB flash drive to .

Modifying and flashing firmware carries inherent risks, including the potential to "brick" (render your device unusable). The following risks are particularly significant: using the wrong firmware for your device can brick it; Secure Boot ensures only signed firmware runs, so a mismatch can prevent booting; corruption of the MBOOT.img (the primary bootloader) is often unrecoverable without specialized hardware. Also, incorrectly configured scripts can lead to a partial or failed flash. An incompatible checksum or CRC value can also cause boot failures. To dump firmware from an Mstar-based device: :

| Component | Function | |-----------|----------| | mstar_dump | Extracts raw NAND/NOR flash dumps into individual partitions (boot, kernel, rootfs, etc.) | | mstar_unpack | Decompresses and decodes MStar-specific packed filesystems (e.g., SquashFS with custom headers, LZMA chunks) | | mstar_repack | Rebuilds a valid firmware image from modified partition files | | ms_mkbootimg | Creates a boot image with MStar’s custom header (different from Android standard) | | cramfs-utils (modified) | Often needed because MStar uses altered CRAMFS or SquashFS variants |
