Hi @Patch0603,

Welcome to the community,

I am sorry to hear about the issues you have had

The first step I suggest would be to hold down the Power Button and the Volume + key together for around 10 seconds. This should restart the handset and may allow you to boot the device up.

However as this happened directly after being submerged, you may need to contact Customer Care within your region, as the device may need to be examined by a service agent.

Use my signature below to find contact details for your region.

I am sorry for any inconvenience.

I'm sorry to hear that, but you have to contact your Local support to get it inspected and/or repaired.
