The Samsung Galaxy A7 2017 International models are now being upgraded to Android 8.0.0 Oreo.
These updates are being rolled out in stages for all users, but it will take a while before it reaches every single Galaxy A7 A720F devices. The updates are released over-the-air, but you can use the ODIN app below and flash the new firmware manually by following the instructions in this post.
The tutorial can be used by those that are running a custom ROM on their devices, as ODIN can install the official update over it, and then you simply factory reset the system partition for it to boot successfully.
Check the following guidelines before starting the manual update:
- the tutorial has to be applied only for the 2017 Samsung Galaxy A7 devices.
- the model of your phone has to be the SM - A720F.
- do not use the tutorial for other different models, as the guide will not work.
- download the Samsung USB drivers from here and install them on your PC.
- for the update process you need to use ODIN 3.13.3.
- for Odin to connect with your phone via usb cable you need to enable USB Debugging from Developer Options and to install the above usb drivers.
- the Developer Options might be hidden, so you will have to unhide that menu first: go to Settings> About Phone> Software Info and tap seven times on the Build Number text.
- return to Settings, find Developer Options and enable USB Debugging.
- you can flash the update over rooted firmware, but you need to know that root access won't survive the update process.
- if you also had a custom Recovery installed, then you will see it replaced by a stock Recovery after the update is done installing.
- you can flash the new update over custom ROMs, but you will have to Factory Reset the phone after the update is done installing.
- the custom ROM will be wiped by the Factory Reset and it will allow the Galaxy A7 2017 to boot in normal mode.
- the Factory Reset process steps are listed at the end of the guide.
- Factory Resetting the device won't remove any data from internal storage, but you will see the system partition getting wiped, so no installed apps will survive the update.
- if your phone is 100% stock Android 7.0 firmware, then you can continue to the next step of this post.
- read the whole post and do not skip any steps.
- this guide has to be applied by advanced users, we cannot be blamed in case you brick the phone nor in case you lose any data files.
How to install Android 8.0.0 Oreo official update for Galaxy A7 2017:
- Download the Android 8.0.0 Oreo A720FXXU3CRD3 archive file from here.
- When the download is done you need to extract the archived contents. Save all files on your PC.
The obtained files are all featuring the A720FXXU3CRD3 version in its name, and all of them are using a tar.md5 extension. Don't extract any further than that.
- Download Odin 3.13.1 zip from here.
Extract the files from the zip and save them on your PC.
- Power off the phone.
- Boot your device in Download Mode.
- the Download Mode boot guide linked above is for Galaxy A5, but it will work the same for Galaxy A7.
- Launch Odin 3.13.1 exe on your PC.
Connect the Galaxy A7 to PC via usb cable.
Wait for Odin to add the device, and then get to the next step.
- if the phone is not added you need to reinstall the usb drivers.
- Go back to Odin main screen and load the update files extracted at step 2:
Click BL and load the BL_A720FXXU3CRD3 tar.md5 file.
Click AP and load the AP_A720FXXU3CRD3 tar.md5 update file.
Click CP and load the CP_A720FXXU3CRD3 tar.md5 update file.
Click CSC and load the HOME_CSC_A720FXXU3CRD3 tar.md5 update file. Do not load the CSC-only named file, as that one tells Odin to wipe clean the phone.
- Press START to confirm the update process.
- wait for the update to be installed.
- When installation is done you can see the PASS message shown by ODIN and the phone will reboot.
Unplug the device and wait for first boot of Oreo OS to be completed.
These were all the steps you had to follow in order to complete the update.
If the FAIL message is displayed by the ODIN app, then you have to repeat the whole tutorial more than once. If you repeat installation you need to make sure the phone meets all requirements and that you won't skip any steps.
If the PASS alert is shown by ODIN, but your device enters in a boot loop or it gets stuck at the boot animation screen for more than 20 minutes without doing anything, then you are force to Factory Reset the device.
The Factory Reset process is going to wipe clean the system partition and that is why this has to be applied by those that have installed Android 8.0 official firmware over a custom ROM.
Here's how to factory reset the device:
- power off the Galaxy A7 2017.
- boot it in Recovery Mode.
- press and hold Volume UP + Home + Power buttons at the same time.
release the buttons when the Recovery Mode menu loads.
- select 'wipe data/ factory reset' option.
- reboot phone in normal mode and you are done.
