Agreed! NEVER, NEVER flash the firmware of any SSD to an old version.
If the SSD won't work for some reason with the new FW and all other fixes to moboard and Windows are exhausted it may be time to contact the SSD manufacturer to RMA the SSD.
Most SSD have at least a 3 year warranty and some are 5 years.
Fortunately for me, rolling back from this latest firmware 10G to 0F works fine. With the new 10G firmware, my m4 would sometimes not be recognized by the BIOS on boot, like others have experienced.
The improved TRIM response time for the 10G firmware appears to be at the cost of write latency.
If you really want to see some performance improvements, update to the latest official intel RST drivers
188.8.131.520. My 4k writes improved form low 80 MB/s to 110 MB/s with these.
