Why is my phone stuck in factory mode? (Samsung galaxy s5)

[AC Question]

I accidently dropped my phone in the toilet and wuickly retrieved it. After a short time, i took it appart and put it into rice and left it for a day. When i tried to turn the phone on, it worked but wouldnt charge. I put it back in the rice but now its stuck on factory mode and says 'UDC START'. What do i do?

Welcome to Android Central! There may not be much you can do--it's likely due to water damage on the motherboard. Rice isn't a guaranteed fix--this technique might be better: http://forums.androidcentral.com/am...ow-s/477140-guide-oh-no-my-phone-got-wet.html
