Xiaomi Redmi Note 4 (nikel) Schematic

BIOS .7z 1.21 MB Shared

Xiaomi Redmi Note 4 schematic for the nikel codename, a compact 1.21 MB 7z archive. Despite the firmware category, its contents should be circuit diagrams, not a dump for programming. The sheets are handy for mapping supply rails, measuring expected voltages at test points, and following charge, backlight and audio circuits when hunting faults. Keep in mind that the Redmi Note 4X mido and this nikel device use different hardware, so match the codename and board markings before working from these pages.
