Cannot Boot Sony Ericsson W850i

[FelixCat]

I cannot boot my Sony Ericsson W850i. Either with or without battery and still using charger, it turns on but then turns off. See this video on YouTube: https://www.youtube.com/watch?v=_5oHq8I9fOQ

Thanks.

Try to reinstall the os with sus,if that it possible.

How can I do that if phone does not boot? It is not Android based phone and I don't know which OS it has but it is from old ones.

I thought SEUS had even the older phones in their list.
