Samsung ODIN If you would like to flash ROMs in the .tar format on your Samsung phone, you have to do it with Samsung’s own leaked factory software called “ODIN”. You can also make use of the open source Heimdall application, which works similarly, and is available on Mac and Linux as well.

   Samsung Kies should be installed for the drivers to get installed, if you don’t have Kies, don’t worry. Get the drivers from (SamFirmware Link). Go to the page, select your device, and select “Download” next to “Drivers”.
   Download Odin : (Dev Host Link)
   Download Samsung ROM file for your device. Official ones can be found here : (SamFirmware Link)
   Power off your device.
   Now while pressing volume down and home button simultaneously, keep the power button pressed
   This will bring you to the download mode custom binary warning screen
   Press volume up to confirm
   Phone will enter download mode. Connect to the computer.
   Drivers will be installed.
   Fire up Odin.
   Odin should show a blue text such as “0:[COM3]” written in the ID:COM box. [Note: The COM port will vary from system to system, so do not assume it to be always 3]
   Select the ROM you downloaded. (If its a single file, it should generally be PDA). Confirm that the files are selected in their respective boxes.
   Make sure “Auto Reboot” and “F. Reset Time” is checked and that “Phone EFS Clear” and/or “Flash Lock” is NOT checked.
   Take a deep breath and click “Start”.
   After the flashing process is complete there will be a green “PASS” displayed and the phone will reboot.
   Done! ROM succesfully flashed!

Troubleshooting If you experience a bootloop (phone constantly reboots and reboots on the boot screen) or a soft brick (powering on the phone shows an orange triangle with a phone and computer), don’t be afraid. XDA to the rescue! For a bootloop:

   Take out the battery.
   Wait for 3 min.
   Put the battery in. Do NOT power on the phone.
   Keep pressing Volume Up + Home simultaneously and press the power button to turn on the device.
   Once the phone shows the model number screen, leave the buttons.
   Your phone will boot into recovery.
   Select “Wipe data/ Factory reset”. (Volume Up for going up and Volume down to go down)
   After the reset is done, select “Reboot system now”.
   The phone will reboot and you should be all fine.

For a soft brick:

   You probably flashed some faulty firmware or firmware not meant for your device.
   If instead of “PASS” it shows “FAIL”, step 3 is the way out.
   Download the correct firmware and flash again.

Run It!

Kita dapat menjalankan image yang kita buat menggunakan emulator atau flash ke device. Perlu kita ketahui bahwa kita harus menentukan target build menggunakan lunch, biasanya akan sangat sukar di jalankan kalau image tersebut di jalankan ke target yang tidak di tujukan sebelumnya.

Cek Device


adb devices

Flash ke Device

Untuk flash ke device, kita butuh menggunakan fastboot yang biasanya sudah termasuk dalam path setelah kita telah sukses build. Buat device agar masuk dalam fastboot mode baik secara manual dengan cara menekan tombol yang benar saat booting, atau melalui shell menggunakan perintah

adb reboot bootloader

Tampaknya untuk mem-flash device harus dilakukan dari folder .zip dari product yang kita buat

cd ~/android-cyanogenmod/out/target/product/e980/

Cek fastboot mengenali device

fastboot devices

Jika device sudah dalam mode fastboot, jalankan

fastboot flashall -w

opsi -w akan menghapus partisi /data di device. Ini berguna jika kita melakukan flashing untuk pertama kali ke sebuah device, jika tidak maka cara ini tidak berguna.

Beberapa perintah fastboot lainnya

fastboot erase boot
fastboot erase cache
fastboot erase recovery
fastboot erase system
fastboot erase userdata
fastboot flash bootloader bootloader.img
fastboot reboot-bootloader
fastboot -w update namaimage.zip


  • Masukan device dalam mode recovery (CWM atau TWRP)

Cek dulu

adb devices

Hasilnya kira-kira

* daemon not running. starting it now on port 5037 *
* daemon started successfully *

  • pindah ke folder lokasi file zip image
  • Pilih di CWM
wipe data/factory reset
wipe cache partition
install zip > install zip from sideload
  • Lakukan di laptop
adb sideload <fileimageandroid>.zip

Lakukan beberapa kali untuk file.zip yang ingin kita instalasi

adb sideload cm-12.1-20160410-NIGHTLY-e980.zip 
adb sideload open_gapps-arm-5.1-nano-20160416.zip

adb reboot

Enable USB debugging on your android device. Install adb and USB driver for your device model Samsung, HTC, Sony, LG, Motorola, Google. Connect your device to PC by USB cable

To boot into download mode for Samsung devices type in cmd window :

adb reboot downloadreboot download

To boot into bootloader mode for most Android devices type in cmd window :

adb reboot-bootloaderreboot-bootloader

To boot into recovery mode for all Android devices type in cmd window :

adb reboot recovery

Emulate sebuah Android Device

emulator di tambahkan ke path kita secara automatis saat proses build. Untuk menjalankan emulator, ketik,

$ emulator

Fastboot is a command line tool used to directly flash the filesystem in Android devices from a host via USB. It allows flashing of unsigned partition images. It is disabled in production devices since USB support has been disabled in the bootloader. You must have an Engineering SPL, or an SPL that is S-OFF.

After installing the Android SDK or ADB Standalone you can use 'fastboot' in addition to the more common ADB.

Verify SPL S-OFF

With the exception of the Google Nexus One (which has an OEM unlock), when you boot the device into the bootloader, you should see S-OFF (security off) on the top line. If you see S-ON, or you see a four-color rainbow background, the SPL does not support fastboot. You will need to install a fastboot compatable SPL, such as HardSPL or any of the Engineering SPLs for various devices. See the device specific page for further instructions.

Access bootloader

  1. Make sure you have ADB or the SDK installed.
  2. Download fastboot for the appropriate operating system for your computer.
  3. Place the executable in the proper place, usually:
    • Linux: ~/android_sdk/tools/ or ~/bin/
    • OS X: ~/android-sdk-macosx/platform-tools/
    • Windows: C:\android-sdk-windows\tools
  4. Turn off the device.
  5. Boot device into bootloader
  6. Make sure the device is in FASTBOOT and not HBOOT
  7. Connect the device to the computer via USB.
  8. On your computer, open terminal and run (you may need elevated privileges for this):
    fastboot devices
You should see something similar to:

Typical Partition Layout

For Reference when flashing partitions

Name Nandroid .img Information Contained Mount Point Notes
splash1 N/A Boot image ("T-mobile G1" image) mtdblock0? size: 320x480x2. Different from bootanimation.zip.
recovery N/A A 'backup' kernel, initrd, and OS
for system recovery / maintenance
mtdblock1 Can flash custom recovery.img (Amon_Ra, ClockworkMod, etc).
Accessed by holding [home] while booting.
boot boot.img The main kernel and initrd mtdblock2 Can flash custom boot.img
system system.img The main OS mtdblock3 This is the /system partition
cache cache.img Temp storage mtdblock4 Unused. Can be re-partitioned.
userdata data.img User data and settings mtdblock5 This is the /data partition


Manual Nandroid restore

Make a Nandroid backup, and copy the folder off your SD card to your desktop.

cd ~/Desktop/path/to/backup/
fastboot flash userdata data.img
fastboot flash system system.img
fastboot flash boot boot.img
fastboot reboot

Flash Custom Recovery.img

fastboot flash recovery /path/to/<recovery>.img
fastboot reboot

Flash Custom boot.img

You should make a Nandroid backup first, in case you need to recover your boot.img

fastboot flash boot /path/to/<boot>.img
fastboot reboot


If you are developing a kernel, you may find it helpful to delete your boot.img and recovery.img to force booting into fastboot:

fastboot erase boot
fastboot erase recovery

You can then manually boot from your custom kernel and a ramdisk:

fastboot boot <kernel> <ramdisk>

Once you have a working kernel and ramdisk, you can automagically combine them within fastboot:

fastboot flash:raw boot <kernel> <ramdisk>
