I just cannot resist.
What you have done here is create a thread about new firmware for the Micron C400, not the Crucial m4. Then another user has asked for links to PREVIOUS firmwares as there are potential issues with the LATEST firmware, 010G.
One of those links was to the PREVIOUS firmware 0309, which you have since overwritten with 010G.
So you have now re-downloaded 0309 and re-flashed your SSD backwards and then amended the thread title to "0309 firmware is out!!" not remembering it was actually released 11 months ago.
Words simply cannot begin to explain the level of complete stupidity which has just transpired.
