Please note that using ("Press "Shift +8" to enter password recovery mode"). "Shift+8" is equal to "*" character at the English keyboard.
In Turkish keyboard or German keyboard, "Shift+8" means "(" character. So, "Shift+8" doesn't work to enter the recovery mode.
Please press only "*", on foreign keyboard, it should work to enter to recovery mode.
