How to unlock the Lovable achievement in Fallout 4 - Definitive Guide
Now Codsworth loves it when you mod your weapons or armor. So every time you visit your preferred settlement to mod something you will make (or at least have a chance to make) Codsworth happy. Note that it has a cooldown until you receive a new like from him.
Old method, obviously patched, sadly:
If you want to boost it you can go sleeping for 48h and then mod something again and receive a new like from codsworth.
If you pay enough attention you can see a popup in the top left corner of the screen once the relationship increases. There are several stages of how much he likes you (neutral->respect->love->idolize). Every time it increases he will start a conversation with you by himself if he's somewhere around you.
If you have him at maximum it will net you the perk 'robot sympathy' which gives you +10 damage resistance for energy weapons from robots.
In case you have him with you as a companion, he also likes generosity, giving away items and nice or peaceful behavior.
What he doesn't like is selfish behavior, murdering non-hostiles, picking owned (red) locks, speech success, pickpocketing and theft.
If you don't switch between already owned mods you can make progress towards the 50 weapon mod achievement while increasing the relationship with Codsworth;
if you want to maximize any other companions relationship, you can find a list of what they like, what not and what perk they net you on this site;

note; sometimes it happens that you have to do something your companion doesn't like or you do it by accident and haven't saved your game recently to just load it and have it undone. But that's no reason to worry, it will not prevent you from reaching maximum relationship with them, it will just take a bit longer (except you do something to make them hostile like murdering them or someone friendly, try to avoid that ).
*if you're going to vote negative please tell why in the comments so I can improve the solution if needed (in case something gets patched or anything alike), thanks!
Thanks to TonySki for spell checking the solution by putting it through Microsoft Word spelling and grammar check!
Now, just totally undress yourself and fast-travel between a few locations (I fast-travelled to Goodneighbor, Diamond City market, Sanctuary Hills and Abernathy Farm). I chose settlements because you are safe upon arrving there. Each time you arrive at a location, and you are naked, Cait will like it.
Even better, if you stock up on booze and chems, if you drink alcohol or take a chem upon arrival at a location and waiting a few seconds, you will get a second like in most cases (beer doesn't count).
With this method, you will get 1-2 likes every couple of minutes, making this, I believe, the fastest way to improve a relationship with a companion. It took me only around 45 minutes to get Cait's personal quest, and another few minutes after I completed her quest, to reach the maximum level.
Edit: alternative solution with McCready, who you will find in the Third Rail in Goodneighbor. He likes when you steal something. Find a good spot for stealing (for me, the best one was the USS Constitution). Make sure you won't be caught by NPCs. Then, steal one item, Mc Cready will like it. Save and quit, reload your save, steal something again, rinse and repeat.
Each companion will chat with you 3-4 times as you get them to like you more, and when you get the achievement, you will see "[companion] idolizes you" in the top left of your screen. Once you see this, do the final dialog with the companion for a permanent perk AND the achievement.
First make sure you have good hacking and locksmith abilities by unlocking their perks. (You have to unlock them anyways for their related achievements)
Know, to get Piper as your companion, go to Diamond City and she will be outside of Diamond City. Interact with her after and agree to help her out. She will then ask you for an interview, accept and she will become your companion. Make her your companion and as you explore the wasteland you will encounter many things to lockpick and hack. Piper likes it when you pick locks and hack terminals, so keep her around as you explore and after enough lockpicking and hacking you will get the achievement.
Each companion has a set of likes and dislikes. I was with Piper for a long time in the game and was the companion I ended up getting max relationship level with. She liked it when I lockpicked doors and hacked Terminals, as well as being generally good to people in conversations. She didn't like, when I stole things from people, persuaded people or threatened people. It come up at the top left that "X Liked That", "X Loved That", "X Disliked That", "X Hated That". Once you reach a certain level of the relationship, they'll start a conversation with you about something. Always choose the "Flirt" option when it is there. Eventually they'll be a "Romance" option after around 4 or so different conversations. Choose this and you'll more than likely be rewarded the trophy. Piper turned me down but I still got the trophy for max relationship level. Unfortunately there is no way to check your current level with your Companion.
Dogmeat cannot be used for this achievement.
In order to reach the maximum relationship level with a companion you need to complete quests with the person, perform actions they like (Piper for instance likes me picking into things), and avoid doing things your particular companion does not like (Piper for instance does not like me persuading people).
For a full breakdown of likes/dislikes, check the Fallout 4 Wiki.
I'll tell you how I got the trophy.
I took Deacon as my partner, you can recruit him by completing 2 quests of the “community” Underground. In my opinion, it’s easier to take an achievement with him (if you play as a good guy.)
Deacon likes it when you pick locks, hack terminals, that's it. Plus, while you're hacking locks and terminals, boost your hacking trophies along the way. Secondly, Deacon likes it when you do good deeds and speak honestly with other NPCs.
Actually. There are 3 stages of relationships. Every new stage of a relationship begins when your partner tells you, “we need to talk.” If your partner wants to talk about something, then you are on the right track. When talking, be sure to support your partner. After 3 frank conversations you will receive an achievement.
