So to reverse: If they typed 00ж30 with Russian layout active but intended English, then each Russian letter corresponds to the US key.

Then the original string "00ж30 дщфвук ьутг" is the garbled output. We need to guess: if you type English word in Russian keyboard layout, what word produces дщфвук ? 00ж30 дщфвук ьутг

So whole string: 00;30 l]aden meng — still not right. Maybe they intended Russian but typed in English layout.
