Step 5 – Open ODIN on your computer. Connect your phone to your computer while your phone is in the Download Mode.
Step 6 – If your phone is connected successfully, one of the ID:COM boxes will turn yellow with the COM port number. This step might take some time.
Step 7 – Now select the files that you have to flash/install on your phone. These files are to be found from the extracted files in Step 1.
- Click on ‘AP’ and select file with ‘AP’ in its name.
- Click on ‘CP’ and select file with ‘MODEM’ in its name. Ignore this step if there is no such file.
- Click on ‘CSC’ and select file with ‘CSC’ in its name. Ignore this step if there is no such file.
- Click on ‘PIT’ and select the .pit file. Ignore this step if there is no such file.
- Click on ‘BL’ and select file with ‘BL’ in it’s name. Ignore if there is no such file.
If you are using an older version of ODIN or flashing a firmware which doesn’t have the above mentioned file name format then look below for the abbreviations to the old name format. Do note that only file name changes, the functionality and back end process remains the same so don’t worry.
- AP = PDA
- BL = Boot Loader
- CP = Modem
Step 8 – In ODIN, check the Auto Reboot and F. Reset Time options. As for the Re-Partition option, check it ONLY if you selected a .PIT file in the above step.
Step 9 – Now click on the Start button in ODIN. Installation process will start and would take a few minutes to complete.
Step 10 – After the installation is completed, your phone will restart. After you see the home screen, unplug your phone from the computer.

Backup and Other Important Tips
Please take a look at the following tips and important points you need to take care of. These are important, as we don’t want anyone losing their personal data or apps.
Always backup your important data that you might need after you install a new custom ROM, an official software update or anything else. Make a backup for just in case, you never know when anything might go wrong. Read: How to Backup Android Apps, Text Messages, WhatsApp, Call History.
Samsung users can also back up data using Samsung Smart Switch to your computer. Smart Switch helps to move data across different Android devices i.e moving Samsung Galaxy S7 Edge backup data to Samsung Galaxy S9 / S9+.
If you already have a custom recovery (ClockworkMod, TWRP etc.) installed on your phone, we strongly recommend a backup using that as it creates a complete image of your existing phone set up. [Tutorial: How to Backup Android Phone using TWRP]
A few more optional tips that you should remember:
1. Having problems connecting your Android phone to the computer? You need to enable USB debugging mode. See here: How to Enable USB Debugging — for Gingerbread, Ice Cream Sandwich, Jelly Bean, KitKat, Marshmallow, Nougat and Oreo.
2. Make sure your Android device is charged up to 80-85% battery level. This might help you: How to Check Battery Percentage. Why? Because, if your phone goes off suddenly while installing a custom ROM, flashing an official firmware update or installing mods etc. — your phone might get bricked or go dead permanently. No one wants that, right?
3. Most of the tutorials and how-to guides on Team Android are for factory unlocked Android phones and tablets. We recommend NOT to try our guides if your phone is locked to a carrier, unless we have specified the carrier name or device model.
