Hey guys so I finally was able to fix my gta 5 freezing problem after 2 weeks. All these methods are all on the youtube… sorry I am too lazy.
Three best methods that helped me were….method 2, method 6 and method 7.
Method 1: deleting tons of game data and friends you don't play with anymore. I first started to delete my game files that I didn't use anymore. Eventually, I factory reseted my ps3 itself. NOTE: back up your data in to things like usb drive. Keep your game data to minimal when putting it back on the ps3. this did not help me much but it might help for you. this is the method that rockstar suggest but it did not have any effect on my ps3.
Method 2: Used the fan mode. what this does is it puts your ps3 fan to its max speed spin for a moment. this blows all your dust within ps3 away. My friend and I did this method and it had a lot of effect. I strongly recommend this.
Method 3: Getting rid of your corrupted files. You can either do this from safe mode or just plugging your power code out while you are at the main menu of ps3.( don't worry it wont damage your ps3) I recommend this one also.
Method 4: clean your ps3. Take your ps3 apart physically and clean it. It helps a lot. It makes the ps3 run smoothly without the chance of overheating. It didn't help me but it might help you.
Method 5: ok this method is not on the internet. One of the problem i had with my ps3 was that my ps3 was overheating. So I took the top cover off and just left it open. This way there are way more air ventilation. Make sure you put the cover on top of your ps3 when you are not using it since dust can get in your system. Also you can put four pieces of rubber beneath your ps3. it helps the keep the bottom part cool ( this rubber method is on the internet). I strongly recommend this one.
Method 6: Reinstall the patch and the game itself. I strongly recommend this.
Method 7: buy a new copy of the disc. my disc was semi scratched so I bought a new one and now it runs smoothly. This ended my problem. you can try disc cleaner too but i don't think it helped on mine.
Method 8: sign out of rockstar social club and your internet. Then sign back in. This did not help me but it may help you.
Method 9: if all the above doesn't work then it is either your internet strength or your ps3. I would replace the disc reader thing or your hard drive. there are a lot of guides out there in terms of how you can replace the specific parts of your ps3. It could also just be your internet strength being super weak. At this point though i suggest you get the ps4. but you can also send your ps3 to sony and fix it. I didn't have to do this.
Ways you can avoid freezing:
use only invite session. (less stress on your hard drive.)
try not call your mechanic. ( this helped me a lot)
drive slowly ( this kind of helped me)
Also try not to open your ps3 menu while your game is loading ( this helped me a lot)
If your ps3 freezes:
press eject button rather than turning it off.
