Step Install Custom ROM Recovery

Persiapan:

• Sudah unlock bootloader perangkat.
• Download file berikut:
• boot.img
• dtbo.img
• vendor_boot.img
• Firmware.zip (ROM yang mau diinstall)

Langkah-langkah:

1. Masuk ke Mode Fastboot

• Matikan HP.
• Tekan dan tahan tombol Volume Bawah + Power hingga masuk ke Fastboot Mode.

2. Flash Recovery Files

Buka Command Prompt di folder tempat file .img kamu berada, lalu jalankan perintah berikut satu per satu:

bash

fastboot -w                               # Wipe data (factory reset)
fastboot set_active a                     # Set partisi aktif ke slot A
fastboot flash boot boot.img              # Flash boot image
fastboot flash dtbo dtbo.img              # Flash dtbo image
fastboot flash vendor_boot vendor_boot.img  # Flash vendor_boot image
fastboot reboot recovery                  # Reboot langsung ke Recovery

Pastikan nama file sesuai. Kalau beda, ganti di perintahnya.

3. Install Firmware (ROM)

Setelah masuk ke Recovery Mode:

• Pilih Apply Update from ADB (di Recovery).
• Lalu di PC jalankan:

bash
adb sideload File-Firmware.zip

(Ganti File-Firmware.zip dengan nama file firmware yang kamu punya.)

Tunggu proses selesai, HP akan menginstal ROM baru.

Proses sideload stuck di 47%: Ini normal di ADB Sideload. Tunggu sampai HP selesai instalasi.

Setelah selesai, pilih Reboot System Now dari Recovery.
