Keep in mind this isn't CFW when you try too update it will crash and tell you what you can downgrade to. If it is below 3.55 then you will be lucky.

Good, you must buy an E3 Flasher I recommend the E3 Flasher nothing else. Maybe from Aliexpress or eBay. Here are some tutorials for your Slim. The taking apart process might be different from models.
