[Samsung Galaxy A3, A5, A7 (2017) Guides, News, & D] jnflos:
This device is more reasonable to buy as it is small and elegant at a decent price.

It is IP68 water-friendly device and the display is much better - higher FPS than on higher resolution OLEDs - good for action games.

Root using CF-autoroot

Download the file from CF-auto-root repository:

https://download.chainfire.eu/1090/CF-Root/CF-Auto-Root/CF-Auto-Root-a3y17lte-a3y17ltexx-sma320f.zip

Unzip the file

Run Odin from the unzipped folder

Browse by clicking AP button the *.md5 file from the unzipped folder

Connect the A320F in download mode (start the device by holding Power+Home+Volume DOWN)

After starting the device in download mode, press Volume UP one to allow the download

A new COM port should be recognized by Odin after the device is connected via USB

Press Start button in in Odin

Rooting will take place automatically and the device will restart twice.

After the first restart you can disconnect the cable from the PC.

Second restart might take a few minutes.

After that you will find the SuperSU app installed.

Other, more complicated methods:

Rooting using custom recovery:

You will need:

SM-A320F with Exynos CPU (waiting for updates on other model)

Android Marshmallow 6.0.1 on your device

Odin v3.0.4 (download link below)

Team Win Recovery Project - TWRP (download link here) or ClockWork Mod Custom Recovery - CWM (download link below)

(Recommended custom recovery: Team Win Recovery Project :good: - more features, newer, works better)

SuperSU-v2.79-201612051815 (latest ZIP version available today - download link below)

SM-A320F TWRP & CWM recovery installation procedure:

On your device enable developer options and then disable OEM lock (FRP lock) for the device to allow you to flash custom recovery

(Activate OEM unlock from developer options menu)

Boot your device in Odin downlaod mode (hold VolDOWN + Home + Power)

Flash the *.tar file of TWRP or for the CWM using Odin's PDA option

(Uncheck Auto Reboot and F. Reset Time)

Force reboot your device (hold VolDOWN + Power for 10 seconds)

SM-A320F SuperSU ZIP installation procedure:

Copy SuperSU-v2.79-201612051815.zip on a microSD card (trough USB data cable or any other method)

Unplug the USB data cable from the phone and shut down the device

Start your device in Recovery mode (Hold VolUP + Home + Power)

(RECOVERY IS NOT SEANDROID ENFORCED - this warning is normal when booting into CWM custom recovery but not with TWRP)

The recovery menu will appear

> Using TWRP Recovery:

Swipe to allow modifications

Tap on Install

Tap on Select Storage at the bottom and select MicroSDCard then tap OK

Browse for the SuperSU-v2.79-201612051815.zip and tap on it to install it

Swipe to install SuperSU (confirm Flash)

> Using CWM Recovery:

Select Install zip update package (use VolDOWN/VolUP to navigate and Power to select)

Select Choose zip from sdcard

Select SuperSU-v2.79-201612051815.zip and press Power to install Super SU

The installation will perform automatically and the device will reboot twice.

First reboot will take longer. Please be patient. After the second reboot you will have SuperSU and root.

Downsides/bugs:

Knox will be tripped the second you flash a custom recovery (Warranty void: 1 - non reversibile)

(That means that you will lose the warranty for your device and that can not be changed)

(Perhaps that's why I personally can't invest more than $300 in a Samsung cellphone ever)

You won't be able to use Knox-related functions including Secure Folder ever again

Because of a SuperSU bug you won't be able to use Smart View (Miracast, project the screen to smart TV) unless you make an edit as follows:

Special thanks to: ashyx for compiling and updating TWRP recovery for SM-A320F and to XN Logos for providing compatible CWM recovery with SM-A320F.

Please feel free to post your attempts on rooting this device and the results. If other methods will show-up I will include them up here.
