Should I not give up hope?

So my phone Huawei p10 has fallen into the toilet (the display has many deep cracks) first you could not turn on the phone no matter what you tried. However, after about a week, the phone went back to work, unfortunately, only a maximum of 20-25 min and then it went out, then I tried to restart it came this vibrated noise when that is concerned, but screen is black (as before a few Days). Does this phone still have a chance or not?

If you put it in a bowl full of rice for 12 hours and it did not help No. But even if, it is rather less recommendable to use a mobile phone that has fallen into the toilet.

I would generally rather say a new phone.

R.I.P

the mobile phone Huawei P10 from Minona888. It lasted a long time and she had a good time with her mobile. Unfortunately, it died because of an accident. It's dead. It has to be buried if it has not been buried yet. Now we may say: rest in peace.

it's dead, buy yourself a new one.

P.S: my condolences

Hajajahhah well you can bother ahahahhaahha

You can already try it… What is broken in a water damage or something breaks is difficult to say.

First of all, you should disassemble it. Youtube typically shows how to do that. Simply your phone + disassemble or enter "teardown". The videos show how to do it step by step. You need a bit of "Handywerkzeug". Amazon or Ebay offers something for small money. Then bissel skill is in demand. Do this in the video.

Haste board battery and something in the hand, knock the battery aside, if necessary, the broken and it must be replaced (about 15 euro). Then get distilled water from the hardware store and bathe board in it (display not, there's water like between glass and display). Let the board dry out and repeat 1-2 times. Then build the phone back together. If display or backside have cracks you can also replace them. Just google for spare parts.

Do not be afraid to try for yourself, even without much technical knowledge you can save a lot here, as the replacement parts are affordable.

Try to open it and get rid of all the corruptions and get it dry
