Controller LED blinking blue but won't work properly

Hi, first time soldering. I just replaced my potentiometer sticks with Gulikit TMR sticks. After I reassembled it, it started blinking without me turning it on.

The buttons don't work and my pc won't detect it wired. Even if I connect it wired, it doesn't charge, LED doesn't turn orange. Pressing or holding the power button doesn't do anything, it just keeps blinking blue like in the video above.

Here's some pictures inside, did I mess up somewhere? Any help is appreciated.

Thanks
