After entering my passphrase multiple times. It did finally unlock. I noticed that when I was sending transaction it didn't seem to sync like a delay and no confirmation, after a couple of goes it when though. Just now went to send the remaining balance. And, I am locked out again! I have done nothing but copy past the same passphrase.
DEV?
Seems like either something wrong with your computer or your computer infected by virus. How can a copy and paste with same password works one minute before but failed one minute after
Yes, I know crazy stuff. I finally go it out. Basically had to manually DDoS myself, with my own passphrase. Then the same with sending the balance. It was a ride. Eventually I managed to send it to a new wallet. The new wallet is working correctly. But, any wallet I restored that .dat to was the same (and I tried all platforms).
So obviously the .dat was corrupted.
Dev, any ideas why?
Sorry, I don't quite get you... Do you mean that your new wallet.dat is working fine, but old wallet.dat could be corrupted?
Yes, original .dat file was corrupted.
There could be a lot of reasons for corrupted file, like fragmented issue that @civilufo mentioned, or computer did not shut down properly, or etc.
So, it is highly recommended to backup your wallet to external storage device such as thumb drive, external hard disk, or cloud storage, because you have no way to recover your coins inside the wallet if corrupted.
Cloud storage is one of the best to backup your wallet because it is an offsite backup, but your have to ensure tight security.
