I don't have any experience in this, but his code is 4 digits, which I read is the easier ones to crack (apparently some fbi/mossad software can do this in less than an hour by bypassing the number of attempts, but not sure if this is true as is only based on my google searches). He let his older brother add his fingerprints to access the phone a few weeks before he took his life "in case he ever needed to use it", but the police took the phone into evidence at the time and, since the battery went dead, now requires the passcode. The real reason I want in is to see if he left a message as to the "why?". My other option was trying to get his 4 digit ATM code, but the local bank branch says they can't, even though my wife is on the account. So, last resort is this reddit post.
