What is the of your Galaxy A5 (e.g., SM-A500F, SM-A500H)?
The bootloader is the software that loads the operating system. You need to unlock it to allow unsigned code (a custom ROM) to run. For Samsung phones, you usually need to enable "OEM Unlock" in Developer Options. If you don't see this option, it may already be unlocked.
Tap and select the GApps zip file (this ensures you have the Google Play Store and Google services).
Versions range from 14.1 (Nougat) up to 17.1 (Android 10) depending on the specific sub-model.

Confirm your device is a 2015 variant of the Galaxy A5 (SM-A500 series). Do not flash these files on the 2016 or 2017 models.
Even with careful steps, you might encounter some hitches. Here’s how to handle them:
Stock Samsung firmware from 2015 is notoriously heavy. Clean, AOSP-based (Android Open Source Project) ROMs remove duplicate apps and useless background services, freeing up precious system RAM.
LineageOS is the gold standard of the custom ROM community. For the Galaxy A5 2015, unofficial builds ranging from LineageOS 14.1 (Android 7.1 Nougat) to LineageOS 17.1 (Android 10) have been maintained by independent developers on forums like XDA Developers.
Do not chase Android 14. Install LineageOS 18.1 (Android 11) or /e/OS . You will get 4+ hours of screen-on time, a snappy interface, and modern app support. The A5 2015 refuses to die, thanks to the dedicated developers on XDA.
