Android Fastboot Operations
⚠️ DANGER ZONE - Fastboot operations write directly to device partitions. Wrong images or interrupted operations can brick devices. Always verify:
- Correct device (check
fastboot getvar product) - Correct images for exact device model
- Bootloader is unlocked (for flashing)
- Battery > 50%
Entering Fastboot Mode
bash
# From ADB (device running)
adb reboot bootloader
# Hardware buttons (most devices)
# Power + Volume Down (hold until fastboot screen)Basic Commands
bash

fastboot reboot recovery # Boot to recovery
fastboot reboot fastboot # Boot to fastbootd (Android 10+)Check Before Flashing
bash
# ALWAYS run these first
fastboot devices # Verify connection
fastboot getvar product # Verify device model
fastboot getvar unlocked # Must be "yes" for flashing

Modern devices have two copies of each partition (A and B).
bash
# Check current slot
fastboot getvar current-slot # Returns: a or b
# Set active slot
fastboot set_active a
fastboot set_active b
# Flash to specific slot

Large partitions (system, vendor, product) live inside a "super" partition.

# 1. Extract boot.img from your firmware
# 2. Transfer to device, patch with Magisk app
# 3. Pull patched image
adb pull /sdcard/Download/magisk_patched_*.img
# 4. Flash patched boot

fastboot erase userdata # Wipe user data
fastboot erase cache # Wipe cache (if exists)
fastboot -w # Format data + cache
# Full flash with wipe
fastboot -w flashall
fastboot -w update image.zipDanger Levels
| Level | Operations |
|---|---|
| ✅ SAFE | devices, getvar, reboot, boot (temp) |
| ⚠️ MEDIUM | flash boot/recovery/dtbo, set_active |
| 🔴 HIGH | flash system/vendor, erase, -w |
| ☠️ CRITICAL | flash bootloader, flash radio, flashing lock with custom OS |
Brick Prevention
Never:
- Flash images from different device models
- Interrupt a flash operation
- Lock bootloader with custom ROM installed
- Flash bootloader/radio without matching versions
Always:
- Verify device with
fastboot getvar product - Keep stock images available for recovery
- Use
fastboot bootto test beforefastboot flash - Maintain battery > 50%
Recovery from Soft Brick
bash
# 1. Enter fastboot (Power + Vol Down)
fastboot devices
# 2. Flash stock boot
fastboot flash boot boot.img
# 3. For dynamic partitions
fastboot reboot fastboot
fastboot flash system system.img
fastboot flash vendor vendor.img
# 4. Wipe if needed
fastboot -w
# 5. Reboot
