What did you change exactly ? Just the antenna or also the GPS module ? Changed both and everything came back to normal.

Awesome tutorial, great explanations and detailed pictures. Changed de GPS module and the Wifi/Bluetooth Antenna for 15€ (including a set of 21 repair tools), everything worked fine and it didn’t took more than an hour.

Tutorial was opened on my PC and I took an additional 3 blank pages, made separated horizontal lines and numbered them from 1 to 39. Taped them next to my working station (so no accident could move them) to affiliate every single removed screw/piece to its step (Ex: 2 screws on step 10, so between the lines of number 10 on my page, left screw on the left side of the paper and right screw on the right side). Made the backwards steps a lot easier and didn’t had to print out the pages, which saves a !&&* lot of ink.

I can just recommend repairing (with caution, it’s still a fragile object) your phone using such great tutorials, saves money and is eco-friendler than just tossing your phone away to buy a new one !
