Want to clean & root old Galaxy A3 (SMA300-FU) but not sure how to do it

Ezek@sopuli.xyz to Android@lemmy.ml – 8 points –

I have an older Samsung Galaxy A3 with an already unlocked bootloader (it comes pre-unlocked) that I want to clean & root. I have a few apps like firefox, some games, DraStic, notesnook, etc. as well as my music. I want to keep all of this of course bug remove all the other bloat i dont need. I dont want a custom ROM or anything. The samsung ROM is good enough (android 6.0.1) I am very unaure on the process though & I dont want my old phone to get bricked so I'd appreciage it if somebody helped me out here, thanks.

Magisk is the root tool to use today.

Look for it on XDA.

Basic procedure:

Extract boot image from rom or phone

Install Magisk to phone.

Use magisk to patch boot image

Copy boot image to PC

Use PC to flash boot image to phone.

okay, exactly how should I flash that boot image to the phone? do I put it in download mode? & will this erase all the data?
