Xbox One analog drift but not the usual one

Common problem, the right stick is drifting upwards. However…

I desoldered the right stick, turned on the controller and even physically without the stick it was still drifting. Then I installed a new analog (entire new unit not just the potentiometers), and it still drifts like if we were in the 90s.

Send help, no visual problems on the board, however the main motor red cable was desoldered when i opened it up, but i dont see how it may affect the controller in any serious way. Btw the controller emits rather quiet buzzing sound tho I heard it’s normal.
