Firmware

AXP.OS for the Samsung J5 does not include any firmware so you need to manually upgrade as described . Skipping this step might result in unexpected behavior and problems later on.

This step needs to be done only once.

Install / Upgrade

recovery

While not recommended you can use any other recovery of course but keep in mind that only the official one is able to verify the AXP.OS OTA signature and is hardened* like the OS itself. So it is HIGHLY recommended to use the official AXP.OS recovery.

Download the latest official AXP.OS recovery from here: leech server

Flashing the recovery should be done by using heimdall (a tool which is e.g. included in mAid):

heimdall flash --RECOVERY recovery.img

then boot to recovery and follow the next topic.

*) note: the hardened recovery by AXP.OS for the J5 includes all security patches and hardening as the OS except for being permissive. exploiting this recovery is not easy though as the only attack surface is the OTA or sideload mechanism (i.e. those must have vulnerabilities and then an attacker still might require additional vulns to get any further). In any case it is WAY more secure then using TWRP or any other custom recovery.
