Initializes the CPU, RAM, and USB stack during cold boot; communicates directly with the computer's VCOM drivers. (Hard brick risk) MBR / EBR1 0x00600000

: Dictates the exact order in which partitions like PRELOADER , BOOT , and SYSTEM must load.

The __NODL_ prefix (meaning wn L oad) is a critical safety flag. It tells flash tools to skip these partitions during normal flashing operations. This is vital because partitions like NVRAM are factory-calibrated for your specific device; overwriting or erasing them can lead to a broken cellular radio or loss of Wi-Fi connectivity. Always treat these partitions with extreme care.

: The label of the block (e.g., PRELOADER , BOOTIMG , RECOVERY , ANDROID ).

| Partition Name | Address (Hex) | Size | Purpose | ||---|---|---|---| | | 0x0 | 256KB | Bootloader stage 1 (initializes DRAM). Flashing this incorrectly = hard brick. | | DSP_BL | 0x40000 | 512KB | Digital Signal Processor bootloader. | | MBR | 0x60000 | 512KB | Master Boot Record for eMMC. | | EBR1 | 0x80000 | 512KB | Extended Boot Record 1 (for internal SD expansion). | | UBOOT | 0xA0000 | 384KB | U-Boot bootloader (fastboot interface). | | BOOTIMG | 0x100000 | 6MB | Kernel + ramdisk (boot partition). | | RECOVERY | 0x700000 | 6MB | Custom recovery (TWRP/CWM) sits here. | | SEC_RO | 0xD00000 | 5.5MB | Secondary security (S-BOOT). | | ANDROID | 0x1280000 | 500MB+ | System partition (/system). | | CACHE | 0x20000000 | 252MB | Cache partition. | | USRDATA | 0x28000000 | Remainder | User data (/data). |
