Fell into snow and haven’t turned on in about a year
Hello Ryan, If it fell into a snow, means it can be water damaged. I thing, it has a short circuit on HomeButton flex or Dock flex. Additionally, after a year of draining battery, that is a dead probably. A my advice in this case is that, if You known some about microsoldering & microelectronics open a phone, disconnect everything and try a start motherboard with no any accessories at all. I’m convinced that a phone will start normally. If you not, find a good repair shop and show them this instruction.
