iPhone x Water Bootloop Cable Touch Screen

Hi

Rice does not solve the problems caused by corrosion due to water coming into contact with electronics. Rice is for dinner, not repair

The impurities in the water causes corrosion and provides circuit paths for the electricity which were not in the phone's operating design and could damage the components. The corrosion starts immediately and is ongoing until it is completely cleaned away

First do not try to charge or to turn on your phone and then remove/disconnect the battery as soon as possible from the phone to minimize any further damage.

Given that it seems to work by only having to disconnect the digitizer flex cable hopefully all it needs is a screen replacement but time will tell.

Here is the ifixit iPhone X 屏幕面板更换 guide that will help with this

If this process seems too daunting, take your phone to a reputable, professional phone repair service, experienced in liquid damage repair and ask for a quote for a repair.
