Have a D855 here. Phone is stock, not rooted. During file transfer, it frozen and rebooted into a white screen asking for "Enter pin/password to decrypt storage". Don't recall setting a pin thus have no clue what to input. Phone started making clicking sound after 10 seconds.
Did a VolDown+Power to entry Factory Reset but return with "e:failed to mount /cache (unknown error 150)"
Able to hold VolDown and enter Download Mode but as I have a Mac here, not sure which tool to execute. Can I recover with *.kdz?
