[Trojan13]

I have a HTC One Max I want to crack. I want to get the data stored on it. The problem is, that it is locked with a pattern lock.
After some research I learned that the only way to get in is via USB Debugging -> adb -> delete key files or bruteforce the pattern. The bootloader is locked but this is only my guess because I can not get into recovery mode because the volume keys are apparently broken. Is there anything else I can try?

These are the methods ive tried:

• Use Android Device Manager
  My google account is not on this phone.
  
  


• Use the 'Forgot Pattern' feature
  My phone hasn't given me the option, not even with one attempt remaining.
  
  


• Perform a factory reset
  I cant use the volume buttons
  
  


• Enable USB Debugging
  Cant enable it without onlocking the phone
  
  


• Boot into Safe mode to bypass third-party lock screen
  its not third party lock screen
  
  


• Crash the lock screen.
  Tried this, can't copy and paste.
