Question Mark folder after dropping it
I dropped my Mac slightly and it hit on the side. When I opened it right after it was on sleep mode, the next day the computer was slow and I could not log in. Then I shut it down and turned on again, a folder with a question mark appears. Then I restarted it pressing command R for Internet recovery, it shows my wifi network but I can't connect to it, after sometime it shows 2002f.
Could be that some cable has a bad connection or I really damaged my HD?
Any help would be really appreciated as now I'm in Brazil and there is only one Apple Store in my city which has no times available to fix my Mac. If anyone can also let me know the tools such as torx screwdriver number to open this model I will be very happy.
