Key concepts

Bootloader menu: device state allowing fastboot/EDL access; stuck here often due to corrupted boot image, partition table, or failed update. Repacking: extracting, modifying (if needed), and rebuilding Android boot/recovery/bootloader images or payload.bin so fastboot can flash them again. fastboot: primary tool to flash partitions when bootloader unlocked or in fastboot mode. EDL/Qualcomm tools: last resort if fastboot fails; often requires authenticated loaders for some devices.

Steps 1) Diagnose device state

Connect device to PC. From terminal:

adb devices (if device is in Android or recovery mode) fastboot devices (if in bootloader/fastboot mode)

Note messages shown in the bootloader menu (errors, fastboot mode, locked/unlocked). Title BlackBerry KeyOne Stuck in Bootloader Menu —
